Description

The present invention relates to a management system.

Conventionally, an R-type disaster prevention receiver has been known as a device for managing a monitoring area (see, for example, Patent Document 1). This R-type disaster prevention receiver is generally electrically connected to disaster prevention equipment such as a bell device and a fire prevention door device, supplies electric power to the disaster prevention equipment side, and transmits an electric signal. Controlled the disaster prevention equipment.

However, the trunk line wiring is connected to the R-type disaster prevention receiver, and a plurality of branch wirings branching from the branch point of the trunk line wiring are provided for one trunk line wiring, and disaster prevention is provided for each of the plurality of branch wirings. Since the equipment was configured to be connected, if a short circuit occurs in one branch wiring, the adverse effect of the short circuit may spread to all the wiring connected to the one branch wiring. rice field.

Therefore, a short-circuit disconnection repeater connected in the middle of the branch wiring (that is, between the branch point of the trunk wiring and the disaster prevention equipment, for example) has been proposed. This short-circuit disconnection repeater electrically cuts off the branch wiring when a short-circuit occurs on the downstream side of the self, thereby preventing the adverse effect of the short-circuit from spreading to all the wiring.

Japanese Unexamined Patent Publication No. 2016-040685

However, in the conventional short-circuit disconnection repeater, for example, since it is necessary to install it for each disaster prevention equipment, a large number of them are required, which increases the installation space of the disaster prevention system or increases the cost of the disaster prevention system. There was a possibility that it would become bulky. In particular, from the viewpoint of more effectively preventing the adverse effects of a short circuit, it is necessary to provide two types of short-circuit disconnection repeaters, one that electrically cuts off electric power and one that electrically cuts off electrical signals. Therefore, there is a possibility that the installation space of the disaster prevention system will be further increased, or the cost of the disaster prevention system will be further increased.

Therefore, the inventor of the present application came up with the concept of manufacturing and using an integrated short-circuit disconnection repeater by aggregating a plurality of conventional short-circuit disconnection repeaters. When a take-off repeater was manufactured and used, there was a possibility that the time and effort required for operation would increase.

That is, in the conventional short-circuit disconnection repeater, there is no way to know whether or not the short-circuit disconnection repeater is electrically cut off. Therefore, in order to identify the short-circuit switching repeater that is electrically cut off, the user needs to know. It is necessary to check the voltage status of the wiring with a predetermined measuring instrument (for example, a hand tester, etc.), which is troublesome. There was a possibility that the number of points to check the voltage status would increase, and the time and effort required for operation would increase.

The present invention has been made in view of the above problems, and an object of the present invention is to provide a management system capable of reducing the time and effort required to operate a relay device.

The management system includes opening / closing determination means for determining an opening / closing state and determination result output means for outputting a determination result of the opening / closing determination means for at least a part of the opening / closing means among the plurality of opening / closing means.

Further, in the management system according to claim 2, in the management system according to claim 1, the relay device is set with a first address that uniquely identifies the relay device, and the plurality of opening / closing means are set. A second address that uniquely identifies each of the plurality of opening / closing means is set in each of the relay devices in which the first address is set, and the opening / closing determining means includes the first address and the opening / closing means. Based on the second address, the open / closed state of the plurality of opening / closing means is determined.

According to the management system according to claim 1, by determining the open / closed state and outputting the determination result, for example, the user confirms the voltage state of the wiring with a predetermined measuring instrument (for example, a hand tester or the like). Since the open / closed state can be grasped without doing so, it is possible to reduce the time and effort required to operate the relay device.

According to the management system according to claim 2, for example, the relay device can be inquired about the open / closed state by determining the open / closed state of the plurality of opening / closing means based on the first address and the second address. Therefore, it is possible to surely grasp the open / closed state. In particular, by using the second address in addition to the first address, for example, the open / closed state can be determined for each opening / closing means, so that the latest open / closed state of only the opening / closing means intended by the user can be determined. Can be output.

According to the management system according to claim 3, the open / closed state of the opening / closing means is determined based on the communication state between the address setting disaster prevention equipment and the management system and the disaster prevention equipment address, for example, to address the relay device. Since it is not necessary to set the number of addresses, it is possible to save the number of addresses to be used when the number of addresses that can be used in the disaster prevention system including the relay device is limited.

According to the management system according to claim 4, by outputting the determination result of the open / close determination means on the relay device side, for example, when performing maintenance work of the relay device, the open / closed state is determined around the relay device. Since it can be grasped quickly, it is possible to improve the efficiency of maintenance work.

The control unit 15 in FIG. 6 is a control means for controlling the disconnection relay device 1. The processing performed by each unit of the control unit 15 will be described later.

(process)
Next, the separation process and the open / close control process executed by the disaster prevention system 100 configured as described above will be described.

(Processing-Disconnecting process)
First, the separation process will be described. FIG. 7 is a flowchart of the separation process (steps are abbreviated as “S” in the following description of each process). FIG. 8 is a connection diagram of a disaster prevention system showing a short-circuit position. The "disengagement process" is generally a process executed by the disconnection relay device of the disaster prevention system 100, and specifically, downstream of each open / close switch of the disconnection relay device of the disaster prevention system 100. This is a process of opening the open / close switch to electrically shut off when an abnormality occurs on the side. Since the disengagement processing performed by each of the disengagement relay devices of the disaster prevention system 100 is the same as each other, the processing performed by the disengagement relay device 1 will be described here. The timing for executing this disconnection process is arbitrary, but for example, after electrically connecting each branch line to each primary side terminal and each secondary side terminal of the disconnection relay device 1 of FIG. It is assumed that the execution is started when the power of the relay device 1 is turned on and the execution is repeated, and the description will be made from the point where the execution is started. The method of electrically connecting each branch line to each primary side terminal and each secondary side terminal of the disconnection relay device 1 is arbitrary, but for example, the user can use the wiring connection diagram of the disconnection relay device 1. It will be connected by wiring based on.

In addition, "abnormality" is a state different from normal, and specifically, it is a state in which continuous use may adversely affect the operation of other devices in the same system, for example. , Short circuit, etc. Here, for example, a case where a short circuit occurs in the second control branch line L23 on the downstream side of the disconnection relay device 1 shown in FIG. 8 will be described as an example. Further, it will be described below that when the power of the disconnection relay device 1 is turned on, each open / close switch of the disconnection relay device 1 is closed and electrically connected. Further, the receiver 5 of FIG. 1 periodically repeatedly outputs an electric signal via the transmission trunk line L11, and power is supplied via the first control trunk line L12, the second control trunk line L13, and the third control trunk line L14. Will be described as being continuously supplied.

In SA1 of FIG. 7, the control unit 15 determines whether or not an abnormality has occurred on the downstream side of each open / close switch of the disconnection relay device 1. Specifically, it is arbitrary, but for example, it may be determined by focusing on the fact that the voltage drops when an abnormal short circuit occurs, or by focusing on the flow of overcurrent. However, here, for example, a case where the determination is made by paying attention to the decrease in voltage will be described. Specifically, the disconnection relay device 1 is provided with a voltmeter (not shown) that measures the voltage of each branch line on the upstream side (receiver 5 side) and downstream side (each disaster prevention equipment side) of each open / close switch. Further, the voltage threshold value for the transmission branch line, which is a threshold value to be compared with the voltage value of the electric signal for determining whether or not a short circuit has occurred in the transmission branch line L21, is recorded in the recording unit 14, and the first The voltage threshold for the control branch line, which is a threshold to be compared with the voltage value of the electric power in order to determine whether or not a short circuit has occurred in the control branch line L22, the second control branch line L23, and the third control branch line L24, is set in the recording unit 14. It is assumed that it has been recorded, and processing is performed as follows.

First, the control unit 15 accesses a voltmeter (not shown), acquires the voltage on the downstream side of each open / close switch of the disconnection relay device 1 (hereinafter referred to as the downstream voltage) for each branch line, and records the voltage. After acquiring the transmission branch line voltage threshold and the control branch line voltage threshold of the unit 14, the acquired downstream voltage is compared with the transmission branch line voltage threshold or the control branch line voltage threshold, which is the threshold of the voltage, and compared. Based on the result, a short circuit is determined for each branch line as described later. Then, when it is determined that no short circuit has occurred on the downstream side of each open / close switch of the disconnection relay device 1 in any of the branch lines, it is determined that no abnormality has occurred (NO of SA1), and the abnormality has occurred. SA1 is repeatedly executed until it is determined that the above has occurred. Further, when it is determined that a short circuit has occurred on the downstream side of each open / close switch of the disconnection relay device 1 in any of the branch lines, it is determined that an abnormality has occurred (YES of SA1), and SA2 is determined. Transition.

Regarding the determination of a short circuit for each branch line, first, for the transmission branch line L21, access a voltmeter (not shown) and acquire the voltage of the electric signal of the secondary side transmission branch line L212 in FIG. 5 as the downstream voltage. Further, after acquiring the voltage threshold for the transmission branch line, if the acquired downstream voltage is equal to or higher than the voltage threshold for the transmission branch line, it is determined that a short circuit has not occurred in the transmission branch line L21. On the other hand, when the acquired downstream voltage is less than the voltage threshold for the transmission branch line, the voltage of the portion connected to the short-circuited position drops as a whole. It is necessary to distinguish whether the side voltage has dropped or whether the downstream voltage has dropped due to a short circuit on the upstream side of the transmission open / close switch Sw1. For example, it is separated as follows. Specifically, focusing on the fact that the voltage other than the disconnected position rises when the short-circuited position is separated from the upstream side, the transmission open / close switch Sw1 is opened and electrically cut off. , Access the voltmeter (not shown) again to acquire the voltage of the electric signal of the primary side transmission branch line L211 in FIG. 5 as the upstream side voltage, and after acquiring the transmission branch line voltage threshold, the acquired upstream side. When the voltage is equal to or higher than the voltage threshold value for the transmission branch line, the short-circuited position is cut off by the above-mentioned cutoff. The transmission open / close switch Sw1 is closed and electrically connected. On the other hand, when the acquired upstream voltage is less than the voltage threshold value for the transmission branch line, the short-circuited position is not disconnected by the above-mentioned cutoff, so that a short circuit occurs on the downstream side of the transmission open / close switch Sw1 in the transmission branch line L21. It is determined that the signal has not been set, and the transmission open / close switch Sw1 is closed and electrically connected.

Further, the first control branch line L22 is the same as the case of the transmission branch line L21, but by accessing a voltmeter (not shown), the voltage of the power of the secondary side first control branch line L222 in FIG. 2 is set to the downstream side voltage. If the acquired downstream voltage is equal to or higher than the control branch line voltage threshold, it is determined that no short circuit has occurred in the first control branch line L22. On the other hand, when the acquired downstream voltage is less than the voltage threshold for the control branch line, it may be that the downstream voltage has dropped due to a short circuit on the downstream side of the first control switch Sw2, or the upstream side of the first control switch Sw2. It is necessary to isolate whether the downstream voltage has dropped due to the short circuit in, but for example, it is isolated in the same manner as in the case of the transmission branch line L21. Specifically, after opening the first control open / close switch Sw2 and electrically shutting it off, the voltage meter (not shown) is accessed again to obtain the voltage of the power of the primary control branch line L221 in FIG. Is acquired as the upstream voltage, and when the acquired upstream voltage is equal to or higher than the control branch voltage threshold, the downstream of the transmission open / close switch Sw1 in the first control branch line L22. It is determined that a short circuit has occurred on the side, and the first control open / close switch Sw2 is closed and electrically connected. On the other hand, when the acquired upstream voltage is less than the voltage threshold value for the control branch line, the short-circuited position is not separated by the above-mentioned cutoff, so that the downstream side of the first control open / close switch Sw2 in the first control branch line L22. It is determined that no short circuit has occurred, and the first control open / close switch Sw2 is closed and electrically connected. Since the determination of the short circuit between the second control branch line L23 and the third control branch line L24 can be performed in the same manner as in the case of the first control branch line L22, detailed description thereof will be omitted. Then, as described above, by determining the short circuit for each branch line in this way, it is determined whether or not an abnormality has occurred on the downstream side of each open / close switch of the disconnection relay device 1.

Here, for example, as shown in FIG. 8, when a short circuit occurs in the second control branch line L23 on the downstream side of the second control open / close switch Sw3, the voltage of the power of the secondary side second control branch line L232 is controlled. When the voltage becomes less than the branch line voltage threshold, the second control open / close switch Sw3 is opened and electrically cut off for isolation. In this case, since the short-circuited portion of the second control branch line L23 is disconnected, the voltage of the power of the primary side second control branch line L231 rises and becomes equal to or higher than the voltage threshold value for the control branch line, so that the second control It is determined that a short circuit has occurred in the second control branch line L23 on the downstream side of the open / close switch Sw3, and it is determined that an abnormality has occurred (YES of SA1).

In SA2 of FIG. 7, the control unit 15 disconnects. Specifically, although it is arbitrary, for example, each branch line determined to have a short circuit in SA1 is specified, and each open / close switch of the disconnection relay device 1 electrically connected to each branch line is set. Open and electrically shut off. Here, for example, the second control branch line L23 is specified, and the second control open / close switch Sw3 electrically connected to the second control branch line L23 is opened to electrically shut off. By performing such processing, the short-circuited position is separated, so that the power of the second control trunk line L13 on the upstream side of the second control open / close switch Sw3 can be maintained in a normal state. It is possible to prevent the adverse effect of the short circuit on the second control branch line L23 from spreading to other devices in the same system (for example, devices on the second device group 92 side). This completes the separation process.

(Processing-Open / close management process)
Next, the opening / closing management process will be described. FIG. 9 is a flowchart of the opening / closing management process. The "open / close management process" is generally a process executed by the disconnection relay device and the receiver 5 of the disaster prevention system 100, and specifically, each of the disconnection relay devices of the disaster prevention system 100. This is a process for managing the open / closed state of the open / close switch. Since the opening / closing management processing performed by each of the disengagement relay devices of the disaster prevention system 100 is the same as each other, the processing in the disengagement relay device 1 will be described here. The timing of executing this separation process is arbitrary, but for example, the execution is started when the power of each device of the disaster prevention system 100 is turned on, and the execution is started at a relatively short time interval (for example, 5 minutes to 10 minutes). It shall be executed repeatedly, and the explanation will be given from the point where the execution is started. Here, for example, the case where the short circuit of FIG. 8 occurs will be described as an example.

In SB1 of FIG. 9, the open / close determination unit 561 of the receiver 5 transmits a request signal requesting a response communication indicating the open / close state. Specifically, although it is arbitrary, the request signal is transmitted to the disconnection relay device 1 via, for example, the communication unit 51, the transmission trunk line L11, and the transmission branch line L21.

On the other hand, in SC1 of FIG. 9, the control unit 15 of the disconnection relay device 1 receives the request signal. Specifically, although it is arbitrary, for example, the request signal is received via the transmission primary terminal Ti11 in FIG.

In SC2 of FIG. 9, the control unit 15 of the disconnection relay device 1 confirms the open / closed state of each open / close switch in response to the request of the request signal. Specifically, although it is optional, for example, it is assumed that a confirmation circuit (not shown) for confirming the open / closed state of the open / close switch is provided, and the confirmation circuit is accessed for confirmation. Here, for example, when the short circuit of FIG. 8 occurs, as described above, the transmission open / close switch Sw1 = “closed”, the first control open / close switch Sw2 = “closed”, and the second control open / close switch Sw3 = “ "Open" and the third control open / close switch Sw4 = "closed", but it is confirmed that the open / closed state is specified.

In SC3 of FIG. 9, the control unit 15 of the disconnection relay device 1 transmits a response signal that responds in the open / closed state in response to the request of the request signal. Specifically, although it is arbitrary, for example, first, the device address and each switch address are acquired from the recording unit 14, and after the confirmation result of SC2 is acquired, each acquired switch address and the acquired confirmation result are obtained. After associating with each other, a response signal including each of the associated switch addresses and the confirmation result and the above-mentioned device address is generated. Next, the generated response signal is transmitted to the receiver 5 via the transmission primary side terminal Ti11, the transmission branch line L21, and the transmission trunk line L11. Here, for example, "Ad1" as a device address and "As1" to "As4" as switch addresses are acquired from the recording unit 14, and "closed", "closed", "open", and "open" are obtained as confirmation results. After acquiring "closed", a response signal including "Ad1-As1: closed-As2: closed-As3: open-As4: closed" is generated and transmitted.

On the other hand, in SB2 of FIG. 9, the open / close determination unit 561 of the receiver 5 receives the response signal. Specifically, although it is arbitrary, for example, the response signal is received via the communication unit 51. Here, for example, a response signal including "Ad1-As1: closed-As2: closed-As3: open-As4: closed" is received.

In SB3 of FIG. 9, the open / close determination unit 561 of the receiver 5 determines the open / closed state. Specifically, although it is arbitrary, for example, the specification information of the device information in FIG. 2 and the open / closed state address information (specifically, the device ID, the device address information, and the switch address information) in FIG. 4 are acquired. Further, the information included in the response signal received by the SB2 is acquired, and the open / closed state of each open / close switch is determined based on the acquired information. Here, for example, for the disconnection relay device 1, the transmission open / close switch Sw1 = "closed", the first control open / close switch Sw2 = "closed", the second control open / close switch Sw3 = "open", and the third. Control open / close switch Sw4 = "closed" is determined.

In SB4 of FIG. 9, the open / close determination unit 561 of the receiver 5 stores open / close information. Specifically, although it is arbitrary, for example, the determination result of SB3 is acquired, and the opening / closing information of FIG. 4 is stored so that the acquired determination result is reflected. Here, for example, "ON", "ON", "OFF", and "ON" corresponding to "Ad1" in the opening / closing information of FIG. 4 are stored.

In SB5 of FIG. 9, the control unit 56 of the receiver 5 determines whether or not to issue an abnormality alarm. The "abnormality alarm" is an alarm for notifying that the above-mentioned abnormality has occurred, and is, for example, an alarm for notifying that a short circuit has occurred. The SB5 is specifically arbitrary, but for example, the opening / closing information stored in the SB4 is acquired, and the determination is made based on the acquired opening / closing information. Then, when "OFF" is not included in the open / close information (that is, when all are "ON"), it is determined that the abnormality alarm is not performed (NO of SB5), and the process proceeds to SB8. Further, when the opening / closing information includes "OFF" (that is, not all of them are "ON"), it is determined that an abnormality alarm is to be performed (YES of SB5), and the process proceeds to SB6. Here, for example, since "OFF" is included in the opening / closing information of FIG. 4 stored in SB4, it is determined that an abnormality alarm is issued.

In SB6 of FIG. 9, the abnormality occurrence position output unit 563 of the receiver 5 identifies the abnormality position which is the position where the abnormality has occurred. Specifically, although it is arbitrary, the judgment result of SB3 is acquired by paying attention to the fact that each open / close switch of the disconnection relay device 1 opens when an abnormal short circuit occurs on the downstream side of the switch. Further, the connection diagram of the device information of FIG. 2 is acquired, and the downstream side of the open open / close switch is specified as an abnormal position based on the acquired information. Here, for example, between the portion marked with the short-circuit position in the second control branch line L23 in FIG. 8 (that is, between the disconnection relay device 1 and the smoke prevention repeater 32 in the second control branch line L23). Part) is specified as an abnormal position.

In SB7 of FIG. 9, the control unit 56 of the receiver 5 issues an abnormality alarm. FIG. 10 is a display example of the alarm screen. Specifically, although it is arbitrary, for example, the abnormality occurrence position output unit 563 acquires the specific result of SB6 and the connection diagram of the device information of FIG. 2, and an alarm that displays the abnormal position based on the acquired information. A part of the screen is generated, and the judgment result output unit 562 acquires the judgment result of SB3 and superimposes the judgment result on the above-mentioned generated part of the warning screen to complete the warning screen. Next, the control unit 56 issues an abnormality alarm by displaying the alarm screen completed in this way on the display unit 54. The "alarm screen" is a screen for issuing an abnormality alarm, and is, for example, a screen for displaying information for specifying an abnormal position and an open / closed state. Here, for example, the alarm screen of FIG. 10 is generated and displayed. Specifically, the abnormality occurrence position output unit 563 generates and displays the connection diagram image G1 that specifies the connection diagram, and also generates and displays the abnormality position image G2 (for example, a highlighted image) that indicates the abnormality position. Also, an abnormality notification image G3 (for example, a message image and an arrow image indicating an abnormality position) indicating that an abnormality has occurred is generated and displayed, and the determination result output unit 562 displays the open / closed state. An open / close state image G4 to be specified (for example, an image showing "open" indicating that it is open or an image showing "closed" indicating that it is closed at a position corresponding to each open / close switch) is generated and displayed.

Further, the determination result output unit 562 of the receiver 5 outputs the open / close information in the SB 8 after it is determined in the determination of the SB 5 in FIG. 9 that the abnormality alarm is not performed (NO of the SB 5). FIG. 11 is a display example of the open / closed state display screen. Specifically, although it is arbitrary, for example, the opening / closing information is output by acquiring the connection diagram of the device information in FIG. 2 and the determination result of SB3, generating an open / closed state display screen, and displaying it on the display unit 54. .. The "open / close state display screen" is a screen that outputs the determination result of the open / close determination unit 561. Here, for example, the open / closed state display screen of FIG. 11 is generated and displayed. Specifically, a connection diagram image G11 is generated and displayed, a normal notification image G13 (for example, a message image) indicating normality is generated and displayed, and an open / closed state image G14 is generated. indicate. The connection diagram image G11 and the open / closed state image G14 here are the same as the connection diagram image G1 and the open / closed state image G4 of FIG. This ends the open / close management process.

(Effect of embodiment)
As described above, according to the present embodiment, by determining the open / closed state and outputting the determination result, for example, the user confirms the voltage state of the wiring with a predetermined measuring instrument (for example, a hand tester or the like). Since the open / closed state can be grasped without any need, it is possible to reduce the time and effort required to operate the disconnection relay device 1.

Further, by determining the open / closed state of each open / close switch based on the device address and the switch address, for example, the open / closed state can be inquired to the disconnection relay device 1, so that the open / closed state can be reliably grasped. It becomes possible.

Further, by outputting the position where the abnormality has occurred, for example, it is possible to easily grasp the position where the abnormality has occurred, so that the abnormality can be quickly recovered.

[Variation example with respect to the embodiment]
Although the embodiments according to the present invention have been described above, the specific configuration and means of the present invention shall be arbitrarily modified and improved within the scope of the technical idea of each invention described in the claims. Can be done. Hereinafter, such a modification will be described.

(About the problem to be solved and the effect of the invention)
First, the problem to be solved by the invention and the effect of the invention are not limited to the above-mentioned contents, and may differ depending on the implementation environment and the details of the configuration of the invention, and only a part of the above-mentioned problems. May be resolved or only some of the above effects may be achieved.

(About distribution and integration)
Further, the above-mentioned configuration is a functional concept, and does not necessarily have to be physically configured as shown in the figure. That is, the specific form of dispersion or integration of each part is not limited to the one shown in the figure, and all or a part thereof can be functionally or physically dispersed or integrated in any unit. Further, the "device" in the present application is not limited to a device composed of a single device, but includes a device composed of a plurality of devices.

(About communication)
Further, regarding the communication between the receiver 5 and the disconnection relay device 1 related to the transmission / reception of the request signal (SB1 and SC1) and the transmission / reception of the response signal (SC3 and SB2) of FIG. Although it has been described that the transmission is performed via the transmission trunk line L11 and the transmission branch line L21, the present invention is not limited to this. For example, a transmission line other than the transmission trunk line L11 and the transmission branch line L21 is provided, and the communication unit of each device is configured to communicate via this transmission line, or communication is performed so as to perform wireless communication between the devices. By configuring the unit, it may be configured to perform wired communication or wireless communication by this transmission line. With this configuration, even if an abnormal short circuit occurs in each transmission branch line connected to the transmission trunk line L11, it is possible to reliably perform the open / close management process.

(About the branch line connected to the disconnection relay device)
Further, in the above embodiment, the case where two types of branch lines are connected to the disconnection relay device 1 has been described, but the present invention is not limited to this. For example, it may be configured so that only branch lines of the same type are connected. That is, it may be configured so that only four control branch lines are connected, or it may be configured so that only four transmission branch lines are connected.

(About output of abnormal position)
Further, in the above embodiment, as shown in FIG. 10, the case where the abnormal position is displayed and output in the connection diagram has been described, but the present invention is not limited to this, and for example, for the abnormal position, the abnormality occurrence position output unit 563 , Each device may be displayed at the location specified by the installation location information in FIG. 3 on the map specified by the map information, and then the wiring shown in the connection diagram may be superimposed and displayed and output on this map. Audio may be output from the speaker.

(About abnormality judgment)
Further, the determination of the abnormality of the above embodiment has been described on the premise that the receiver 5 repeatedly outputs an electric signal and continuously supplies electric power, but the present invention is not limited to this, and for example, It is assumed that the disconnection relay device 1 is provided with a voltage application circuit that applies a voltage for confirming whether or not the branch line on the downstream side of the disconnection relay device 1 is short-circuited, and after opening each open / close switch. , An arbitrary value of voltage is applied from this voltage application circuit to the branch line on the downstream side, and as described in the embodiment, the voltage of the branch line on the downstream side is compared with each threshold value, and based on the comparison result. You may judge. In this case, when each open / close switch is closed, a voltage of an arbitrary value is applied to the branch line on the downstream side from the voltage application circuit, and the voltage of the branch line drops, and there is a possibility of a short circuit. After opening each open / close switch, apply voltage again from the voltage application circuit to the branch line on the downstream side, compare the voltage of the branch line on the downstream side with each threshold, and short-circuit based on the comparison result. Confirmation may be determined. When processing in this way, it is possible to reduce the frequency of opening the open / close switch.

(About restoration)
Further, after SA2 in FIG. 7, the control unit 15 of the disconnection relay device 1 may determine the restoration. Specifically, it is arbitrary, but for example, in the same manner as in the case of "(about abnormality determination)" in the modified example, a voltage of an arbitrary value is applied from the voltage application circuit to the branch line on the downstream side, and the downstream side is used. The voltage of the branch line of is compared with each threshold value, and it is judged whether or not the judgment is restored (that is, whether or not the short circuit is resolved) based on the comparison result. May be closed.

(About omission of processing)
Further, although each open / close switch is opened / closed in the determination of SA1 in FIG. 7 of the above embodiment, for example, when it is determined that a short circuit has occurred, the open state is maintained without closing. The processing of SA2 may be omitted.

(About output in open / closed state)
Further, in the above embodiment, as shown in FIG. 10 or 11, a case where the open / closed state, which is the determination result of the open / close determination unit 561, is displayed and output in the connection diagram has been described, but the present invention is not limited to this, for example. Regarding the determination result of the open / close determination unit 561, the determination result output unit 562 may be configured to output on each disconnection relay device side of the disaster prevention system 100. Specifically, an indicator light (for example, an indicator light corresponding to each open / close switch) for displaying the status of the own open / close switch is provided in a housing (not shown) of each disconnection relay device of the disaster prevention system 100. Then, the determination result output unit 562 transmits information for specifying the open / closed state of each open / close switch to each disconnection relay device of the disaster prevention system 100, and displays each indicator lamp so that the open / closed state can be specified. The determination result of the open / close determination unit 561 may be output on each disconnection relay device side of the disaster prevention system 100. Here, for example, a total of four indicator lights corresponding to each open / close switch are provided in the housing of the disconnection relay device 1, and then green light is emitted when the switch is closed and red light is emitted when the switch is open. It may be configured to do so. When configured in this way, by outputting the determination result of the open / close determination unit 561 on the disconnection relay device 1 side, for example, when performing maintenance work on the disconnection relay device 1, the disconnection relay device Since the open / closed state can be quickly grasped around No. 1, it is possible to improve the efficiency of maintenance work.

(About the output of the open / closed state of the disconnection relay device itself)
Further, after providing at least a part of the functions of the receiver 5 of the above embodiment to the disconnection relay device 1, the technique of the indicator lamp of the above-mentioned "(about the output in the open / closed state)" is applied. It may be configured so that the open / closed state is determined and the determination result is displayed by the indicator lamp only on the disconnection relay device 1 side without communicating with the receiver 5.

(Regarding individual inquiries regarding open / closed status)
Further, in the above embodiment, the case where the receiver 5 inquires about the open / closed state of each open / close switch for each disconnection relay device of the disaster prevention system 100 has been described. However, for example, by designating the device address and the switch address. , The open / closed state may be inquired for each open / close switch in the disconnection relay device of the disaster prevention system 100. Specifically, for example, the receiver 5 transmits a request signal including "Ad1" and "As1", so that the disconnection relay device 1 transmits a response signal indicating an open / closed state of the transmission open / close switch Sw1. It may be configured to do so. In this configuration, in particular, by using the switch address in addition to the device address, it is possible to determine the open / closed state for each open / close switch, so that the latest open / close switch only intended by the user can be determined. It is possible to determine the open / closed state and output it.

(About output in open / closed state)
Further, in the above embodiment, an address is set for the disconnection relay device of the disaster prevention system 100, and the open / close determination unit 561 of the receiver 5 uses the address for the disconnection relay device in SB3 of FIG. The case of determining the open / closed state has been described, but the present invention is not limited to this, and for example, the address of the disaster prevention equipment other than the disconnection relay device of the disaster prevention system 100 (hereinafter referred to as the disaster prevention equipment address) and the disaster prevention equipment address are used. The open / closed state may be determined based on the communication between the set disaster prevention equipment and the disaster prevention receiver. FIG. 12 is a connection diagram of a disaster prevention system of a modified example. The concept here can be applied to any disaster prevention system, but here, for example, a case where it is applied to the disaster prevention system 100a of FIG. 12 will be described. Addresses are not set for the disconnection relay devices 1a and 4a of the disaster prevention system 100a, and the detectors 61 to 63 are connected to the transmission branch line L21 or the like. The detectors 61 to 63 are disaster prevention equipment, specifically, an address setting disaster prevention equipment in which a disaster prevention equipment address that uniquely identifies oneself is set. In this case, the open / close determination unit (open / close determination means) of the receiver 5a, which is a disaster prevention receiver, is based on the communication state between the detectors 61 to 63 and the receiver 5a and the disaster prevention equipment address of the detectors 61 to 63. Then, among the open / close switches of the disconnection relay devices 1a and 4a, the open / close state of the open / close switch electrically connected to the detectors 61 to 63 is determined.

Specifically, the open / close determination unit of the receiver 5a attempts to communicate with the detectors 61 to 63 by using the disaster prevention equipment addresses of the detectors 61 to 63, and determines based on whether or not the communication can be performed. Specifically, it is arbitrary, but for example, when communication with the sensor 63 cannot be performed, it is determined that at least the transmission open / close switch of the disconnection relay device 4a is open, and the detection is performed. When communication with the device 63 is possible, it is determined that at least the transmission open / close switch of the disconnection relay device 4a is closed. Further, for example, when communication cannot be performed with the detectors 61 and 63, it is determined that at least the transmission open / close switch of the disconnection relay device 1a is open, and the detectors 61 and 63 are used. If communication is possible between the two, it is determined that at least the transmission open / close switch of the disconnection relay device 1a is closed. In this configuration, the open / closed state of each open / close switch is determined based on the communication state between the detectors 61 to 63, which are the address setting disaster prevention equipment, and the receiver 5a, which is the management system, and the disaster prevention equipment address. Therefore, for example, since it is not necessary to set an address for the disconnection relay devices 1a and 4a, it is used when the number of addresses that can be used in the disaster prevention system 100a including the disconnection relay devices 1a and 4a is limited. It is possible to save the number of addresses.

The sensors 61 to 63 are configured to operate based on the electric power from the first control branch line L22, the second control branch line L23, and the third control branch line L24, and then the above technique is applied. It is possible to determine not only the open / closed state of the transmission open / close switch but also the open / closed state of each control open / close switch. Further, after setting the disaster prevention equipment address for the bell repeater 31, the smoke prevention repeater 32, and the gas repeater 33, the above-mentioned technique may be applied to determine the open / closed state.

(Other features)
Further, other functions may be implemented in the main body built-in type or the plug-in type for the disconnection relay device 1 of the above embodiment, for example, a lightning protection function may be implemented, or. A noise prevention function for preventing noise due to MRI electromagnetic waves from being transmitted to the upstream side may be implemented.

(About abnormality)
Further, in the above embodiment, the case where the "abnormality" is a short circuit has been described as an example, but the present invention is not limited to this, and the disconnection, the noise associated with the disconnection, the chattering, etc. are defined as the "abnormality" and the noise. In order to prevent the spread of adverse effects such as noise and chattering, it may be configured to perform electrical disconnection.

(About features)
Further, the features of the above-described embodiment and the features of the modified examples may be arbitrarily combined.
