DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an electric switchgear, and more particularly to an electric switchgear having a plurality of switchgears and a controller for collectively controlling the operation of these switchgears.

[0002]

2. Description of the Related Art In the technique disclosed in Japanese Patent Application Laid-Open No. 1-192986, a plurality of electric blinds are centrally controlled by a single controller, so that the heights of the plurality of blinds and the angles of the blades can be adjusted for lighting and cooling / heating efficiency. By providing the correct values for both sides and aligning the blinds, an electric blind system is shown that helps to save on heating and cooling costs and maintain the aesthetics of the entire building.

[0003] The electric blind disclosed in this publication will be described. In this electric blind, a plurality of blinds are provided in each of a plurality of zones.

In each zone, one of a plurality of blinds is determined as a parent device, and the rest is determined as a child device. In each zone, the blind of the master unit is connected to the blind of one slave unit via a signal line, and the blind of this slave unit is connected to the blind of the next slave unit via another signal line.

[0005] In this way, the blinds of the master unit and the blinds of the slave unit are connected in series. The blinds of each master unit in each zone are connected to a centralized controller that can control each blind individually or collectively.

[0006] In the electric blind constructed as described above, the central controller instructs the raising and lowering of the blinds and the opening and closing of the blades of the master unit and the slave unit collectively or individually for each zone or all zones. Then, the master unit first receives the command signal. If the command signal is for collectively or individually instructing vertical movement and opening and closing in the zone to which the parent machine belongs, the parent machine raises and lowers the blinds of the parent machine and opens and closes the blades.

If the command signal is a command for collectively or individually raising and lowering and opening and closing the slaves in the zone to which the master belongs, the master outputs the command to the slaves. Each child device raises / lowers the blinds and opens / closes the wings of the child device if it is a command for raising / lowering and opening / closing the blind to the child device.

When a signal for instructing the vertical movement of the blinds and the opening and closing of the blades for all the zones is output from the centralized controller, all the blinds are set to the same height and the same blade angle. If you apply such an electric blind to a blind pointing in the same direction to the sun,
By operating all the blinds in the proper state as described above, the cost of cooling and heating can be saved and the appearance of the entire building can be maintained.

[0009] In addition to the electric blind system described above, electric blind systems for controlling a plurality of electric blinds from a plurality of controllers are also commercially available.

In this electric blind system, when a command signal is output from a plurality of controllers to a plurality of blinds, a situation may occur where the command signal is not reliably transmitted to the blinds due to interference or the like. If the operator manually outputs the command signal by operating the controller, the same operation can be performed again to output the command signal, and the blind can be reliably brought into the state as instructed.

[0011]

However, if the above-mentioned situation requiring the re-output of the command signal occurs during the automatic operation using the timer function, the command signal is surely output. There is a problem that the blind is not transmitted to the blind and does not go to the commanded state.

In addition, when the controller outputs a command signal to the blind and the blind is moving up and down or opening and closing the blades accordingly, the blind hits an obstacle or the like and stops in the middle of the operation. .

FIG. 3 is a flowchart of a main routine showing the operation of the controller and control unit of FIG.
In the flowchart of FIG. 3, the transmission and reception of signals between the controller and the control unit are associated with each other.

In FIG. 3, the controllers (1a to 1e) perform a command content and time setting process T1 and a command signal output process T1.
2. The control unit (3a) repeatedly executes a response signal input process T3 and a notification / notification process T4 according to the response signal.
3e) repeatedly executes a command signal transmission process T5, a command signal reception process T6, and a response signal output process T7.

Each of FIGS. 4 to 10 shows a detailed flowchart of each of the processes T1 to T7 of FIG. Next, the operation of the electric blind system of FIG.
This will be described with reference to the flowcharts of FIGS.

Now, assume that the controller 1a is used to control the blind device 2e to open.

First, a command content and time setting process T1 is performed. When the operator inputs from the timer input unit 13 of the controller 1a to open the blind device 2e at a predetermined time, if the input is correct, it is stored in the timer storage unit 14 (S1 to S3 in FIG. 4).

Next, a command signal output process T2 is performed. The microcomputer 11 determines whether or not there is any content stored in the timer storage unit 14 (S4). If not, the microcomputer 11 returns to the main routine. It is determined whether or not the current times match (S5), and if they do match, it is determined whether or not transmission of the command signal IS based on the contents stored in the timer storage unit 14 has been performed for the first time after a predetermined time (S6). ).
If it is the first time, the microcomputer 11 converts the content stored in the timer storage unit 14 into a command signal IS and outputs it to the control unit 4a via the command signal output unit 16 (S7), and shifts to the input signal preparation process for the response signal RS. (S8), and returns to the main routine.

On the other hand, if the predetermined time has not come (NO in S5), or if the command signal IS is not transmitted for the first time after the predetermined time (NO in S6), it is determined whether or not the command signal IS is to be re-output. (S9). If the re-output wait Chinara determines whether or not count a predetermined wait time for the re-output of the command signal IS (S10), if the waiting time during the count, and determines whether the count has been completed (S11 ), The command signal IS is output again if the counting of the waiting time is not completed or the counting of the waiting time is not being performed (S7, S7).
8).

If the transmission is not the first transmission after a predetermined time (NO in S6) and the command signal IS is not to be output again (NO in S9), the process returns to the main routine.

Next, a command signal transmission process T5 is performed by the control unit 4a corresponding to the controller 1a.
The microcomputer 21 determines whether or not the command signal IS has been input via the command signal input unit 28 (S30). When it is determined that the command signal IS has been input, the microcomputer 21 uses the transmission path signal receiving unit 26 to perform signal transmission on the transmission line 6. Is checked (S31).

When the transmission line signal receiving section 26 confirms that the transmission line 6 is in a no-signal state (YES in S32), the microcomputer 21 stores the destination designation information IF from the contents of the input command signal IS. , The command signal IS is transmitted to the transmission line 6 via the transmission path signal transmission unit 25 (S3
3) It is determined whether the transmission has been completed (S34). If the transmission is completed, the response signal RS in which the transmission completion state information is set
Is output to the controller 1a via the response signal output unit 27 (S35), and the process returns to the main routine.

On the other hand, if the command signal IS has not been input from the controller 1a , the process returns to the main routine. Or transmission line 6 by Den sending passage signal receiving unit 26 that is in signal congestion is confirmed (NO in S32), or command signal IS
Has not been transmitted to the transmission line 6 (N in S34).
O), response signal RS in which transmission incomplete state information is set
Is output to the controller 1a via the response signal output unit 27 (S36), and the process returns to the main routine.

Next, reception processing T6 of the command signal is performed. The control unit (4) of the blind device (2a to 2d)
Each of the microcomputers 21a to 4d receives the command signal IS from the transmission line 6 via the transmission line signal receiving unit 26 (YES in S37), but it is not a signal addressed to itself, that is, the transmission destination of the reception signal IS. Since the specified information does not match the identification information ID (NO in S38), the signal is ignored and the process returns to the main routine.

The microcomputer 21 of the control unit 4e of the blind device 2e transmits the command signal IS to the transmission line 6.
Is received via the transmission line signal receiving section 26 (YES in S37), the signal is addressed to itself, that is, since the destination designation information of the received signal IS matches the identification information ID stored in advance (YES in S38). ), A process corresponding to the command signal IS is performed. Hereinafter, this processing will be described.

When the microcomputer 21 of the control unit 4e of the blind device 2e confirms that the protection function of the motor 23 has not been activated (NO in S39),
The motor 23 is driven via the drive unit 22 according to the content of "open" which is the operation designation information of the command signal IS (S40),
The status signal SS in which the operation start status information and the transmission source designation information are set is transmitted to the transmission line 6 via the transmission line signal transmission unit 25 (S41). If any abnormality occurs during the operation, the state signal SS in which the abnormal state information and the transmission source designation information are set is transmitted in the same manner (S43), and the process returns to the main routine.

On the other hand, if it is confirmed that the protection function of the motor 23 is operating (NO in S39), the status signal SS in which the operation non-start status information and the transmission source designation information are set is transmitted to the transmission line 6 via the transmission line 6. Transmission via the signal transmission unit 25 (S4
2) Return to the main routine.

Next, a response signal output process T7 is performed. Control units 4b to 4 of blind devices 2b to 2e
The microcomputer 21e receives the status signal SS from the transmission line 6 via the transmission line signal receiving unit 26 (S4).
5) Since the status signal SS is not a signal from the blind device of the transmission destination of the command signal IS, that is, the stored transmission destination specification information IF does not match the transmission source specification information of the received status signal SS (S46). NO), ignores the signal, and returns to the main routine.

The microcomputer 21 of the control unit 4a of the blind device 2a transmits the status signal SS to the transmission line 6
From the transmission line signal receiving unit 26 (S4
5) Since the status signal SS is a signal from the blind of the transmission destination of the command signal IS, that is, since the stored transmission destination specification information IF matches the transmission source specification information of the received status signal SS (S46). (YES), the status signal SS is converted into a response signal RS, output to the signal line 5a via the response signal output unit 27 (S47), and the process returns to the main routine.

Next, a response signal input process T3 is performed. When the microcomputer 11 of the controller 1a is in a state of waiting for the input of the response signal RS (Y in S12)
ES), when response signal RS is input from signal line 5a via response signal input unit 17 (YES in S13), response signal R
It prepares to analyze the contents of S and notify the notifying unit 19 (S14). When it is confirmed that the blind of the command target is abnormal, that is, when the received signal RS includes abnormal state information (YES in S15), the content of the response signal RS is reported to the management center or the like via the reporting unit 18. (S20) and return to the main routine.

If it is confirmed that the blind of the command target has started the command operation without any abnormality, that is, when the received signal RS includes the operation start state information (Y in S16)
ES), the command to the blind device 2e is completed by the timer operation, and the process returns to the main routine. If it is confirmed that the blind of the connection destination has not completed transmission of the command signal IS, that is, if the reception signal RS includes the transmission uncompleted state information (NO in S17), the command signal IS is immediately transmitted again. (S21, S19), the process returns to the main routine. When it is confirmed that the blind of the command target has not started the command operation by the protection function of the motor 23, that is, when the reception signal RS includes the operation non-start state information (YES in S17), a predetermined standby time has elapsed. Later, the command signal IS is output again (S18, S19), and the process returns to the main routine.

As described above, while the transmission of the command signal IS is not completed, or while the blind device at the target is not operated by the command signal IS, the transmission operation of the command signal IS is repeatedly performed. The probability that the blind device can receive the command signal IS can be increased.

Next, a report / notification process T4 according to the response signal
Is performed. If the microcomputer 11 of the controller 1a is waiting for the notification of the response signal RS (YE in S2)
S), the content of the input response signal RS is transmitted via the notification unit 18 to notify the operator of the management center or the like (S2).
3) If not waiting for notification (NO in S22), determine whether to wait for notification of response signal RS (S24), and if waiting for notification, notify the operator of the content of input response signal RS via notification unit 19 to the operator. (S25), and returns to the main routine. Therefore, the operator can quickly respond to the abnormal state.

In the above-described embodiment, the microcomputer 11 of the controller 1a sends the command signal IS when the time stored in the timer storage unit 14 and the time counted in the calendar unit 12 match. Although the signal is output once to the line 5a via the command signal output unit 16, the signal may be output a plurality of times at regular intervals.

In the above-described embodiment, when the microcomputer 21 of the control unit 4a of the blind device 2a receives the command signal IS from the signal line 5a via the command signal input unit 28, the microcomputer 21 receives the command signal IS from the transmission line signal receiving unit 26. The transmission state of the transmission line 6 is checked, and when it is confirmed that there is no signal, the command signal IS is transmitted to the transmission line 6. Is also good.
