Description

The present invention relates to a lock shift monitor device and a lock shift monitor system, and in particular, a lock shift monitor device for determining the quality of the lock adjustment state of a turning machine, and a plurality of lock shift monitor devices and centralized management. It relates to a lock shift monitor system in which a room forms a network.

(Conversion function and lock function of the turning machine)
FIG. 5 shows a lock can 53 that operates in conjunction with the operation of the tongue rails 13a and 13b in the tumbling machine 30. The rolling machine 30 is provided with a conversion mechanism for switching the course of a train by branching a track by bringing a pair of tongue rails 13a and 13b into close contact with or separating from each other with respect to the basic rail. Further, the turning machine 30 connects the lock can 53 to the tongue rails 13a and 13b, moves the lock can 53 in conjunction with the operation of the tongue rails 13a and 13b, and at the end of the conversion operation, the tongue rail 13a, It has a lock function to maintain the state of 13b.

FIG. 6 shows a mechanism for detecting the deviation of the lock can 53. The tumbling machine 30 is locked by inserting the lock piece 51 into the notch groove 55 provided in the lock can 53, and can be moved by being pulled out. If the position of the lock can 53 deviates significantly from the reference position during the locking operation in the above-mentioned conversion, the lock piece 51 cannot be inserted into the notch groove 55 provided in the lock can 53. The cause is, for example, misalignment of the rail or the rolling machine 30 due to repeated passing of the train. In addition, foreign matter may be caught in the gap between the tongue rails 13a and 13b and the basic rail. In these cases, the tongue rails 13a and 13b cannot be locked normally, which hinders the safe running of the vehicle.

As shown in FIG. 6, the lock can 53 is provided with a lock mechanism by the lock piece 51 and the notch groove 55, and a shift amount measuring means by the linear sensor 54 and the measuring piece 52. As shown in FIG. 5, the linear sensor 54 is connected to the detector case 14, and the positions of the notch groove 55 and the measuring piece 52 follow the movement of the lock can 53. Therefore, when the lock can 53 is displaced by "a" in the direction indicated by the arrow in FIG. 6, the plunger 56 of the length (B) becomes the length (B + a). At the same time, the gaps (m) on both sides of the lock piece 51 and the notch groove 55 become gaps (m + a, ma). As described above, the offset amount in the lock mechanism including the lock piece 51 and the notch groove 55 can be measured by the offset amount measuring means by the linear sensor 54 and the measuring piece 52.

In the rolling machine 30, if the lock can 53 is largely displaced during locking, the lock piece 51 is not inserted into the notch groove 55 of the lock can and conversion becomes impossible. Therefore, a "monitoring device" that measures the amount of lock offset, which is the amount of displacement of the lock can 53, transmits information on the lock offset to the outside, and monitors the lock offset has been put into practical use.

The timing for measuring the lock offset amount is preferably immediately after the end of conversion, which is not affected by the passage of the train. In the past, for the convenience of measuring current and voltage as a tumbler monitor, information on the start of conversion of the tumbler was received from the interlocking device. Then, based on that information, the lock shift after the conversion was completed was measured. An interlocking device is a device that links a traffic light in a station yard with a rolling machine to realize an overall security function and operate a train safely.

Patent Document 1 discloses a turnout monitoring device that monitors the strain of a switch adjuster of a turnout. Here, it is described that the timing of starting the operation of the movable rail is correctly grasped, and the apparent strain is compensated without using the temperature sensor.

Patent Document 2 describes a lock state management method for managing the lock state of a turning machine, measuring the amount of displacement of the lock piece from the reference position of the lock can, and numerically managing the data by image processing. It is disclosed. Here, the displacement amount of the lock can is measured from the best shot image in the locked state, the read control number and the measured displacement amount of the lock can are converted into text data, and a management data list is created and stored and / or. Or it is described to output.

Patent Document 3 discloses a conversion state data collection system capable of continuously monitoring the conversion state of a turning machine without laying a communication line. Here, the conversion state measurement storage device is installed at the site where the turning machine is located, and the measurement related to the conversion state of the turning machine is executed for each conversion, and the data is accumulated and stored. After that, when maintenance personnel come to the site and the mobile terminal is connected, the data stored and stored up to now is copied to the mobile terminal. Then, when the maintenance personnel connects the mobile terminal brought back from the site to the conversion state management device, the data stored in the mobile terminal is taken into the conversion state management device, and it is stored and stored in addition to the previous one. Are listed.

Patent Document 4 discloses a lock offset amount detector of a turning machine that enables display corresponding to a narrow range closer to 0 points while maintaining the conventional stepwise display function of the lock offset amount. Has been done. Here, a display is provided for displaying the detected lock offset amount in stages by dividing it into a plurality of ranges, and the range closest to the 0 point of the lock offset amount is switched between a relatively wide range and a relatively narrow range. It is described that it has a display mode switching means.

Although the above-mentioned "monitoring device" that monitors the lock shift has been put into practical use as a part of the function of the "rotating machine monitor" that measures the operating current and voltage during the operation of the turning machine, it is locked. It has not been put into practical use as a dedicated "monitoring device" for monitoring deviations. That is, the conventional "monitoring device" does not exist as a single unit and can be used only as a set with the "rotating machine monitor" having a function of measuring the operating current and voltage during operation of the rolling machine.

Further, the conventional "monitoring device" receives the conversion condition from the interlocking device, polls the data after a predetermined time from the start of the conversion operation, and measures the lock offset amount. However, in the method of receiving the conversion condition from this interlocking device, the interlocking device itself must be modified for connection with the lock shift monitoring device.

Further, in the conventional "monitoring device", a transmission unit is provided outside the lock shift detector, and information is transmitted to the equipment room or the station via the transmission unit. Therefore, there is no device that can monitor the lock deviation by itself, and the configuration for monitoring the lock deviation becomes complicated.

Further, one of the causes of the lock shift is that the rail expands and contracts due to the temperature change, and the relative position between the rolling machine and the rail changes accordingly. Therefore, it is preferable to measure the temperature of the tumbler to verify the correlation with the lock shift. In addition, the lock shift is affected by the flapping of the lock can when the train passes. Therefore, it is preferable to measure the vibration when the train passes and verify the influence on the lock shift.

Further, since the lock offset amount can be measured only at the timing when the turning machine changes, the information obtained by continuously collecting the data cannot be measured. In particular, the relationship between the above-mentioned temperature change and the lock offset amount, and the influence on the lock offset by measuring the vibration when the train passes cannot be verified.

An object of the present application is to provide a lock shift monitor device and a lock shift monitor system that solves such a problem, is independent of the tumbling machine monitor, and can monitor the lock shift by itself without the need for information from the interlocking device. That is.

Furthermore, another object of the present application is a lock shift monitor that can automatically detect the conversion operation of the turning machine and simultaneously measure and monitor external environmental conditions such as temperature and vibration around the turning machine. It is to provide a device and a lock shift monitor system.

In order to achieve the above object, the lock shift monitor device according to the present invention is a lock shift monitor device that receives a conversion operation command of a turning machine from an interlocking device and detects a lock shift.
And detecting the lock deviation point lock unit from the change in output voltage with a change in the stroke of the sensor which occurs due to the conversion operation of the point lock device.

With the above configuration, the timing of the conversion operation of the tumbler, which has been conventionally received from the interlocking device, can be determined from the change that occurs with the conversion operation of, for example, a linear sensor. As a result, the lock shift monitor device according to the present invention does not need to be used as a set with the "rolling machine monitor" having a current and voltage measuring function of the turning machine, and can measure by itself. In addition, information on the conversion operation of the turning machine from the interlocking device becomes unnecessary. That is, the lock shift monitoring device according to the present invention can monitor the lock shift by itself, and can be a cheaper and more functional device.

Further, it is preferable that the lock shift monitoring device determines whether the conversion operation of the turning machine is normal or abnormal from the lock shift and transmits it to the central control room. As a result, it is possible to remotely monitor the normality or abnormality of the conversion operation of the turning machine in the central control room based on the data measured by the lock shift monitoring device.

Further, it is preferable that the lock shift monitoring device detects the lock shift immediately after the conversion operation of the turning machine is completed. That is, the lock shift determines the quality of the lock adjustment state of the rolling machine based on the state immediately after the conversion is completed. This is because, after the conversion is completed, the state after the train has passed is that the lock lock flutters and moves due to vibration, and it is not possible to judge whether the lock adjustment state of the rolling machine is good or bad. As a result, it is possible to judge whether the lock adjustment state is good or bad without being affected by the vibration generated by passing the train.

Further, it is preferable that the lock shift monitoring device calculates at the end of the conversion operation of the turning machine from the start of the detected conversion operation. That is, it is possible to estimate the end time of the conversion operation by adding the time assumed until the end of the conversion operation of the turning machine to the start time of the conversion operation, and set the timing for detecting the lock deviation.

Further, it is preferable that the lock shift monitoring device determines from the change generated by the conversion operation at the end of the conversion operation of the turning machine. That is, for example, the conversion operation of the turning machine can be determined by the operation of two linear sensors for measuring the lock offset amount. As a result, it is not necessary to obtain the timing for measuring the lock offset amount from the interlocking device, and the lock offset can be monitored by itself.

Further, the lock shift monitor device preferably includes a sensor for measuring the internal temperature or vibration. As a result, in addition to the lock offset amount, external environmental conditions such as temperature and vibration can be measured at the same time, and the influence of the external environmental conditions on the lock offset amount can be confirmed.

Further, in the lock shift monitor system, a plurality of lock shift monitor devices and a centralized control room form a network, and the lock shift monitor device stores the lock shift after the conversion operation of the turning machine is completed. A communication management unit that includes a lock shift storage unit and a transmission / reception unit of a monitor device that performs data communication with the central control room, and the centralized control room manages data communication with a plurality of lock shift monitor devices, and a plurality of It is preferable to include a lock shift monitor device and a transmission / reception unit for data communication. As a result, the centralized control room stores data such as lock shift measured at the timing of conversion of the turning machine in the memory of the lock shift storage unit, and centrally manages it together with the current value data at the time of regular periodic polling. Can be sent to the room. Further, the lock shift monitor device can collectively manage a plurality of lock shift monitor devices by the centralized control room.

Further, in the lock shift monitor system, the transmission / reception unit of the central control room polls each lock shift monitor device at a fixed cycle, and each lock shift monitor device responds to the poll and the lock shift storage unit. It is preferable to transmit the lock shift data stored in the monitor device and the current value data of the lock shift from the transmission / reception unit of the monitoring device. By adjusting the polling cycle in this way, it is possible to accurately measure the fluttering state of the lock can, especially when the train passes.

Further, in the lock shift monitor system, it is preferable that the communication management unit sets the polling cycle in advance for each of the plurality of lock shift monitor devices. As a result, when a plurality of lock shift monitor devices are provided, the communication management unit can set the polling cycle according to the characteristics of each lock shift monitor device and collect efficient data. it can.

As described above, according to the lock shift monitor device and the lock shift monitor system according to the present invention, the lock can be independently monitored by the lock shift monitor without the need for information from the interlocking device. A shift monitor device and a lock shift monitor system can be provided.

Furthermore, a lock shift monitor device and a lock shift monitor system that can automatically detect the conversion operation of the turning machine and simultaneously measure and monitor external environmental conditions such as temperature and vibration around the turning machine. Can be provided.

(Configuration of lock shift monitor device)
Hereinafter, the lock shift monitoring device 1 according to the present invention will be described in detail with reference to the drawings. FIG. 1 shows a schematic configuration of one embodiment of the lock shift monitoring device 1 according to the present invention. The lock shift monitor device 1 includes a lock shift processing unit 2, a monitor display unit 12, and a transmission / reception unit 11. Further, the lock shift processing unit 2 is composed of a lock shift control unit 6, a lock shift storage unit 7, a data output unit 8, a temperature data processing unit 9, and a vibration data processing unit 10. With this configuration, the lock shift monitor device 1 according to the present invention becomes a device independent of the monitor of the turning machine 30. Further, the information from the interlocking device is not required, and the lock offset monitor device 1 can monitor the lock offset amount by itself.

The lock shift control unit 6 receives the output voltages from the N-side sensor 3a and the R-side sensor 3b provided on the rotary machine 30, and receives the output voltages of these two N-side sensors 3a and the R-side sensor 3b. The conversion operation of the turning machine 30 is determined from the operation, and the lock deviation amount immediately after the completion of conversion is detected at a predetermined timing. Then, the lock offset storage unit 7 stores the lock offset amount immediately after the end of conversion in the memory as "data immediately after the end of conversion". Further, the lock offset control unit 6 detects the "current value data" of the offset amount at the time of polling at a fixed cycle set arbitrarily.

The temperature data processing unit 9 transmits and receives to and from the temperature sensor 4 provided in the turning machine 30. Then, the temperature sensor 4 monitors the temperature data around the turning machine 30 together with the above-mentioned "data immediately after the conversion is completed" and the current value data of the lock offset amount. Then, the relationship between the lock shift data and the temperature data can be verified.

The vibration data processing unit 10 transmits and receives to and from a vibration sensor 5 provided in the turning machine 30. Then, the vibration sensor 5 monitors the vibration data around the rolling machine 30 together with the above-mentioned "data immediately after the conversion is completed" and the current value data of the lock offset amount. Then, the relationship between the lock shift data and the vibration data is verified.

The data output unit 8 transmits information to the monitor display unit 12 to display the lock shift data, the temperature data, and the vibration data. Specifically, the lock shift data immediately after the conversion by the lock shift control unit 6 is completed, and the temperature data and vibration data which are external environmental conditions.

The monitor display unit 12 displays a numerical value of the displacement amount of the lock piece 51 based on the data input from the N side sensor 3a, the R side sensor 3b, the temperature sensor 4, and the vibration sensor 5, and displays the N side sensor 3a and the R side sensor 3b. The conversion direction with and the determination result of whether or not the lock shift is normally performed are displayed, and the temperature, vibration, etc., which are external environmental conditions, are displayed.

In this way, the lock offset monitor device 1 determines whether the conversion operation of the turning machine 30 is normal or abnormal based on the lock offset amount, and transmits it to the central control room 20. That is, the transmission / reception unit 11 of the lock shift monitor device 1 transmits the data transmitted to the monitor display unit 12 to the transmission / reception unit 22 of the centralized control room 20.

(Conversion operation of the turning machine)
FIG. 2 shows changes in the output voltages of the R side sensor 3b and the N side sensor 3a in the conversion operation of the turning machine 30. It is preferable that the lock shift monitoring device 1 detects the lock shift immediately after the conversion operation of the turning machine 30 is completed. That is, the lock shift determines whether the lock adjustment state of the rolling machine 30 is good or bad based on the state immediately after the conversion is completed. This is because, after the conversion is completed, the state after the train has passed is that the lock can flutter and move due to vibration, and it is not possible to judge whether the locked state of the rolling machine 30 is good or bad. The timing for determining the quality of the locked state of the turning machine 30 will be described with reference to FIG.

In this embodiment, a plunger type linear sensor is used as the sensor. It is known that the relationship between the stroke amount from the center position of the sensor characteristic of this plunger type sensor and the output voltage of the sensor is linear. Therefore, the stroke amount of the plunger type sensor can be detected by measuring the output voltage (V) of the plunger type sensor. In the present embodiment, a plunger type linear sensor is used as the sensor, but the sensor is not limited to the sensor capable of detecting the conversion operation of the turning machine 30, and an optical sensor, a magnetic sensor, an ultrasonic sensor, or the like is used. You may. In the present embodiment, the plunger type linear sensor includes the N side sensor 3a and the R side sensor 3b.
Since it is composed of and, it is displayed as "N side sensor 3a" and "R side sensor 3b". The stroke amount of each of the N-side sensor 3a and the R-side sensor 3b can be measured from their respective output voltages. Further, from the movement of the N-side sensor 3a and the R-side sensor 3b, the conversion operation of the turning machine 30 can be known.

The vertical axis of FIG. 2 shows the output voltage (V) of the sensors 3a and 3b. The horizontal axis of FIG. 2 represents time (T). At the start, the output voltage (V) of the N-side sensor 3a is Va (= 4.975V to 5,025V), and the output voltage (V) of the R-side sensor 3b is Vb (= 1.3V to 3,7V). Deviation-1.5 mm to +1.5 mm), 0.9V to 4.1V (deviation -2.0 mm to +2.0 mm)). At this time, the N-side sensor 3a is in a “bra” state in which it is not converted and locked, and the R-side sensor 3b is in a state in which it is converted and locked. When the conversion operation is started at the time (T ₀ ), the R-side sensor 3b is in the “blurred” state and becomes Va in the same manner as the output voltage (V) of the N-side sensor 3a. When the lock is converted, the lock can move, so that the plunger of the sensor is returned by the spring and is not pushed, and both the N-side sensor 3a and the R-side sensor 3b are in the "bra" state.

The timer starts operating when both sensors 3a and 3b exceed the threshold value (4.5V) for detecting this conversion operation. Then, when both the N-side sensor 3a and the R-side sensor 3b continue in the "bra" state for the determination time "tβ", it is determined that "conversion has started". In the present embodiment, this determination time “tβ” is 1 second. Further, the lock shift control unit 6 is switched to the lock shift detection timing (P) after a certain period of time “tα” has elapsed since both the N side sensor 3a and the R side sensor 3b are in the “blurred” state. The lock deviation after the end is measured and stored in the lock deviation storage unit 7. In the present embodiment, this constant time "tα" is 15 seconds.

After the conversion is completed, the R-side sensor 3b and the N-side sensor 3a remain in the bra state, and the output voltage (V) of the N-side sensor 3a is Vb (= 1.3V to 3.7V (shift-1.). 5 mm to +1.5 mm), 0.9V to 4.1V (deviation -2.0 mm to +2.0 mm)), and the output voltages of the N-side sensor 3a and the R-side sensor 3b are reversed with respect to the start time.

FIG. 2 shows how the output voltages (V) of the N-side sensor 3a and the R-side sensor 3b are disturbed by the vibration of the train passing when the train passes after the lock shift detection timing (P). There is. Information such as the amplitude of vibration when the train passes is stored in the lock shift storage unit 7 because it becomes information such as "whether there is a lot of backlash or little" when servicing or inspecting the rolling machine 30. It is preferable to keep it.

As described above, the lock shift monitoring device 1 sets the lock shift detection timing (P) at the end of the conversion operation of the turning machine 30 after a certain period of time “tα” has elapsed from the start of the detected conversion operation. Calculate. Then, this fixed time "tα" can be set to an empirically reasonable time. However, the lock shift monitoring device 1 may determine the lock shift detection timing (P) of the turning machine 30 from the change generated with the conversion operation. For example, it may be a predetermined time after the reversal of the output voltage values of the N-side sensor 3a and the R-side sensor 3b is detected.

(Lock shift monitor system)
FIG. 3 shows a schematic configuration of one embodiment of the lock shift monitor system 40 according to the present invention in a block diagram. The lock shift monitor system 40 is a system in which a plurality of lock shift monitor devices 1 and a centralized control room 20 form a communication network to transmit and receive. In FIG. 3, the number of lock shift monitor devices 1 of the lock shift monitor system 40 is n lock shift monitor devices 1 corresponding to the turning machine 30a to the turning machine 30n. In this embodiment, only three lock shift monitoring devices 1a, 1b, and 1c are described for the turning machine 30a to the turning machine 30c.

The lock shift monitor device 1 of the lock shift monitor system 40 includes a transmission / reception unit 11 that performs data communication with the central control room 20, and the central control room 20 manages data communication with the lock shift monitor device 1. It includes a management unit 21 and a transmission / reception unit 22 that performs data communication with the lock shift monitor device 1.

The transmission / reception unit 22 transmits polling information (Y) to each lock shift monitor device 1 at regular intervals, and measures the lock shift and external environmental conditions such as temperature and vibration. Each lock shift monitor device 1a, 1b, 1c responds to this polling information (Y), and is a lock shift composed of the lock shift data stored in the lock shift storage unit 7 and the current value data of the lock shift. Data (X) is transmitted from the transmission / reception unit 11 of the lock shift monitor device 1 to the transmission / reception unit 22 of the central control room 20.

The communication management unit 21 sets the polling cycle in advance for each lock shift monitoring device 1. As a result, the communication management unit 21 can set the polling cycle according to the characteristics of each lock shift monitoring device 1 and collect efficient data.

(Lock shift detection method)
FIG. 4 shows a flow diagram of a lock shift detection method according to the present invention. Each step of the lock shift detection method is shown in (S1) to (S10).

As shown in FIG. 5, the lock shift monitor device 1 has an output voltage (V) from the N-side sensor 3a and the R-side sensor 3b, which are linear sensors 54 provided in the lock can 53 of the tumbling machine 30. Is measured (S1). Then, it is determined whether or not it is detected that the start of rolling-over operation of the point lock device 30 (S2). Then, if it is not detected (in the case of No.), the process returns to step 1, and if it is detected (in the case of Yes), the process proceeds to step 3.

In step 3, it is determined whether or not to directly detect the end of the conversion operation and detect the lock offset amount. If the end of the conversion operation is directly detected (in the case of Yes), the process proceeds to step 5. In step 5, it is determined whether or not the end of the conversion operation is detected. Then, when the end of the conversion operation is detected (in the case of Yes), the process proceeds to step 6. On the other hand, if the end of the conversion operation is not detected (No), the process returns to step 3. On the other hand, if No in step 3, it is determined whether or not a predetermined time has elapsed after the start of the conversion operation (S4). Then, the lock offset amount is converted from the output voltage of the sensor (S6).

Next, it is determined whether or not temperature data or vibration data is also required (S7). If necessary (in the case of Yes), the measured temperature data or vibration data is attached to the lock shift data (S8). Proceed to step 9. If it is not necessary (No), the process proceeds to step 9 as it is. Further, the normal / abnormal state of the lock shift is determined and the process ends (S10). When an abnormality of the lock shift is determined in step 10, the abnormality determination information is transmitted from the transmission / reception unit 11 of the lock shift monitor device 1 to the transmission / reception unit 22 of the central control room 20.
