BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a barrier rod motion measuring device for measuring the motion of a barrier rod of a barrier such as a railroad crossing.

2. Description of the Related Art Conventionally, there is known a technique of measuring the operation of a barrier rod in order to determine whether there is an abnormality in a railroad crossing gate (see, for example, Patent Document 1). In the technique described in Patent Document 1, the presence or absence of an abnormality is determined by comparing two or more types of physical quantities detected by a sensor unit attached to a blocking rod with a criterion, and the determination result is sent to a higher management device. to be notified.

JP 2017-105336 A

Here, in the circuit breaker, some symptom may appear before an abnormality actually occurs. However, since the above-described technology only notifies the result of determination as to whether or not there is an abnormality, it is currently difficult for the notification destination to catch the signs of the abnormality prior to the occurrence of the abnormality.

SUMMARY OF THE INVENTION Accordingly, it is an object of the present invention to provide a blocking rod operation measuring device capable of detecting not only the occurrence of an abnormality in a circuit breaker but also the symptom of an abnormality at a notification destination.

In order to solve the above-mentioned problems, the blocking rod operation measuring device is a blocking rod operation measuring device that measures the movement of the blocking rod in the crossing machine, and includes a tilt detection unit that detects the tilt of the blocking rod, and a time A time measuring unit for measuring, and measurement data representing the operation time required for each operation of the lowering operation and the raising operation of the blocking rod, and the operation end inclination of the blocking rod at the end of each operation, are sent to the tilt detection unit. a data generation unit that generates data based on the detection result of and the time measurement result of the time measurement unit; an output unit that outputs the measured data to a predetermined output destination; the inclination detection unit; the time measurement unit; , and the output unit, wherein the housing is installed to move together with the blocking rod, and the tilt detection unit detects the movement of the blocking rod using an acceleration sensor or an angle sensor. is characterized by detecting the inclination of

Generally, in a circuit breaker, the breaking rod is moved up and down by a drive unit having a motor, a driving mechanism, etc., while being balanced by a balance weight attached to the rear end side of the breaking rod. If the operation time and operation end inclination of the breaking rod do not fall within a predetermined range, there is a possibility that the weight of the breaking rod is shifted due to some kind of failure or breakage in the driving section. The abnormalities and signs referred to below are phenomena that can be captured from the operation time and operation end inclination of the breaking rod, such as failure of the drive unit and deviation of the weight of the breaking rod. According to the above-described blocking rod operation measuring device, the measurement data representing the operation time required for each movement and the operation end inclination of the blocking rod at the end of each movement are output to the output destination. output to In other words, since measurement data that can be the source of abnormality determination is output, not only the occurrence of abnormality but also signs of abnormality can be captured using the measurement data at the output destination. In addition, abnormalities and signs thereof may appear separately when the blocking rod is lowered and when it is raised. On the other hand, according to the above-mentioned blocking rod operation measuring device, measurement data representing the operation time and the operation end inclination of each of the descending operation and the ascending operation are output, so that the abnormalities and symptoms that appear individually as described above are not leaked. can be captured without

Moreover, in the above-described blocking rod operation measuring device, a general timekeeping function in a component such as an MPU (Micro Processing Unit) responsible for generating measurement data may be used for timekeeping. That is, it suffices to prepare only one type of physical quantity, that is, the inclination of the blocking rod, as the hardware sensor. As described above, according to the blocking rod operation measuring device, the number of sensors can be reduced, so that the cost of parts can be reduced.

Further, according to the above-described blocking rod motion measuring device, the inclination of the blocking rod can be detected with high accuracy by using the acceleration sensor or the angle sensor which is housed in the housing and provided to move together with the blocking rod. Therefore, it is possible to further improve the accuracy of the measurement data.

Moreover, it is also preferable that the output unit wirelessly outputs the measurement data.

According to this configuration, it is possible to output the measured data to a desired output destination even at a railroad crossing where a long cable is undesirable.

Further, a radio communication unit having a rod-shaped antenna is further provided, the housing is installed on the blocking rod such that the longitudinal direction of the rod-shaped antenna is along the longitudinal direction of the blocking rod, and the output unit is the It is also preferable to wirelessly output the measurement data via the wireless communication unit when the blocking rod is in an upright state.

According to this configuration, the measurement data is wirelessly output when the rod-shaped antenna with high communication performance is erected together with the blocking rod and communication failure is suppressed. can be sent to any destination. The reason why communication failure is suppressed when the bar antenna is erected together with the blocking rod is that when the blocking rod is erected, that is, when the blocking rod is raised, the train, a metal shield, blocks the line between the rod antenna and the output destination. This is because it does not exist between them. In recent years, trains often employ motor control by VVVF inverter control (Variable Voltage Variable Frequency inverter control). When a train passes by, there is a high possibility that harmonic noise generated by this VVVF inverter control will be radiated from the train. By wirelessly outputting measurement data in such a state, for example, the risk of retrying when wireless outputting fails can be reduced, and an increase in power consumption due to retrying can be suppressed.

Further, the data generation unit generates the descent operation time measured by the clock unit when the detection result of the tilt detection unit changes from the descent start threshold to the descent end threshold, and the detection result of the tilt detection unit. It is also preferable to generate measurement data representing, as the operation time, a rise operation time measured by the timer unit when C changes from the rise start threshold to the rise end threshold.

According to this configuration, by comparing the detection result of the inclination detection section and each threshold value, the measurement data representing the operation time of the blocking rod can be generated with high accuracy while suppressing the processing load.

Further, the data generation unit generates an average value of the detection results of the inclination detection unit over a first measurement time after a first waiting time has passed since the detection result of the inclination detection unit reaches the descent end threshold value. , and an average value of the detection results of the tilt detection unit over a second measurement time after the second waiting time has passed after the detection result of the tilt detection unit reaches the rising end threshold, as the operation end tilt It is also preferred to generate measurement data expressed as .

According to this configuration, by generating the measurement data representing the average value of the detection results of the inclination detection section as the operation end inclination, the detection results may not fluctuate due to shaking of the blocking rod at the end of the operation. stable measurement data can be obtained.

Further, it is preferable to further include a sleep control section that, when a predetermined sleep period arrives, suspends the operations of the tilt detection section, the timer section, the data generation section, and the output section during the sleep period. .

According to this configuration, it is possible to reduce the power consumption of the tilt detection section, the clock section, the data generation section, and the output section during the sleep period, so that a power saving effect can be obtained.

According to the above-described blocking rod operation measuring device, not only the occurrence of an abnormality in the circuit breaker but also signs of the abnormality can be detected at the notification destination.

The operation instruction R and the drop signal R are sent from the overall control device 13-1 to the main unit 13a through the contact input/output section 13c. When the train approaches, the operation instruction R changes from H to L, and the warning device 12 starts sounding the warning sound, and after the descent waiting time has elapsed, the barrier 11 starts to lower the barrier rod 11a. It is recognized by the unit 13a. After the descent is completed, the descent state of the crossing gate 11 is recognized by the main unit 13a through the contact input/output section 13c of the railroad crossing equipment box 13 by the descent signal R changing from L to H. When the train has passed, the operation instruction R changes from L to H, so that the alarm device 12 stops ringing the alarm sound and the barrier device 11 starts to raise the barrier rod 11a. recognized by When the descent signal R changes from H to L at the start of the ascent, the body unit 13a recognizes the end of the descent state of the circuit breaker 11.

The change in inclination of the breaking rod 11a in the barrier 11 is shown in the barrier chart TC14. The blocking rod 11a, which stands vertically and has a tilt angle of 0° when no train is present, descends toward a horizontal state with a tilt angle of 90° after the descent standby time elapses after the start of the alarm sound. Start. When the tilt angle reaches 90° in a predetermined descent time, it waits for the passage of the train, and when the train passes and the alarm sound ends, it starts to rise. The operation of the blocking rod 11a is completed when the device is placed vertically with an inclination angle of 0° in a predetermined rising time.

Here, the excessively rapid descent or rise operation of the blocking rod 11a may cause a pedestrian crossing the railroad crossing 1 or a pedestrian standing in front of the railroad crossing 1 to be hit, or the pedestrian's clothing to be caught. may lead to an accident. In addition, excessively slow descent or ascent of the blocking rod 11a prolongs the blocking time of the road R12 passing through the railroad crossing 1, which may cause traffic congestion. Therefore, the descending time and ascending time are appropriately determined in consideration of the safety of pedestrians, traffic conditions, the structure of the gate 11, and the like.

In the present embodiment, the only communication event sent from the main unit 13 a to the blocking rod operation measuring device 100 is notification of confirmation of receipt of the measurement data output from the blocking rod operation measuring device 100 .

A measurement chart TC161 and an output chart TC162 are shown in the blocking rod operation measurement chart TC16.

The measurement chart TC161 shows the measurement process performed by the data generator 113 with respect to the change in the inclination angle of the blocking rod 11a.

In the data generation unit 113, first, the descent operation time TS11 measured by the clock unit 112 when the detection result of the inclination detection unit 111 changes from the descent start threshold value L11 to the descent end threshold value L12 is obtained. Furthermore, the rise operation time TS12 measured by the clock unit 112 when the detection result of the inclination detection unit 111 changes from the rise start threshold value L13 to the rise end threshold value L14 is obtained. Here, the descent start threshold value L11 is the inclination angle when the blocking rod 11a is tilted by a predetermined amount from the vertical (0°) state, and the descent end threshold value L12 is the descent end threshold value L12. (90°) is the inclination angle at a stage a predetermined degree before it falls down to (90°). An example of the descent start threshold L11 is an angle of 5°, and an example of the descent end threshold L12 is an angle of 85°. The rising start threshold value L13 is the angle of inclination when the blocking rod 11a rises up by a predetermined degree from the horizontal (90°) state, and the rising end threshold value L14 is the vertical (0 °) is the tilt angle at a stage before a predetermined degree. An example of the rising start threshold L13 is an angle of 85°, and an example of the rising end threshold L14 is an angle of 5°. Specific values of the descent start threshold L11, the descent end threshold L12, the rise start threshold L13, and the rise end threshold L14 can be arbitrarily set according to, for example, the detection resolution of the tilt detection unit 111. .

Further, in the data generation unit 113, the detection result of the inclination detection unit 111 over the first measurement time TS14 after the first waiting time TS13 has passed after the detection result of the inclination detection unit 111 reaches the descent end threshold value L12. is obtained as the descent operation end slope L15. Further, the average value of the detection results of the tilt detection unit 111 over the second measurement time TS16 after the second waiting time TS15 has passed after the detection result of the tilt detection unit 111 reaches the rising end threshold value L14 is raised. It is obtained as the ending slope L16.

Then, the data generator 113 generates measurement data representing the descending operation time TS11, the ascending operation time TS12, the descending operation end slope L15, and the ascending motion end slope L16 thus obtained.

Processing related to the generation of such measurement data will be described with reference to the flowcharts of FIGS.

The process of this flowchart is started when the blocking rod operation measuring device 100 is activated after the sleep period defined by the sleep control unit 116 described above ends. Then, each element is initialized (step S11), and then enters a standby state (step S12). During this time, it is determined whether or not the detection result of the inclination detection unit 111 exceeds the descent start threshold value L11 (step S13). If it is less than the descent start threshold value L11 (NO determination in step S13), the process returns to step S12 to enter a standby state.

When the descent start threshold value L11 is exceeded (YES determination in step S13), the timing result is recorded by the timing unit 112 (step S14). Next, it is determined whether or not the detection result of the inclination detection unit 111 exceeds the descent end threshold value L12 (step S15). If it is less than the descent end threshold value L12 (NO determination in step S15), the determination in step S15 is repeated so that the data generator 113 waits for the breaking rod 11a to descend.

When the descent end threshold value L12 is exceeded (YES determination in step S15), the descent operation time TS11 is obtained from the time measurement result of the time measuring unit 112 at this time and the time measurement result recorded in step S14 (step S16). ).

Note that the method of acquiring the descent operation time is not limited to the method of obtaining from the time measurement results at two points in time as in the present embodiment. For example, a method of starting time measurement at the time of step S14 and ending time measurement at the time of step S16 to acquire the elapsed time between the two time points as the descent operation time may be employed.

Further, unlike the present embodiment, a timeout may be provided not only for obtaining the descent operation time but also for the operation time until the descent end threshold value L12 is exceeded. That is, if the descent end threshold value L12 is not exceeded by the upper limit time, an abnormality such as the blocking rod 11a not being completely closed due to an object such as a vehicle being caught between the blocking rod 11a and the ground occurs. , the abnormality may be detected. In this case, when an abnormality is detected, the process is stopped, and the detection result of the tilt detection unit 111 at the time of abnormality detection, the time measurement result of the time measurement unit 112, and error information indicating that an abnormality has occurred are sent. , is generated. Then, the measured data is output to the main unit 13a without waiting for the output processing described later.

In the present embodiment, following acquisition of the descent operation time TS11, the data generator 113 determines whether or not the first waiting time TS13 has elapsed (step S17).

If the first waiting time TS13 has not elapsed (NO determination in step S17), the determination in step S17 is repeated so that the data generator 113 waits for the first waiting time TS13 to elapse. When the first waiting time TS13 has elapsed (YES determination in step S17), the detection result of the tilt detection unit 111 is recorded (step S18). Following this recording, the data generator 113 determines whether or not the first measurement time TS14 has elapsed (step S19). If the first measurement time TS14 has not elapsed (NO determination in step S19), the process returns to step S18, and the recording of the detection result by the tilt detection unit 111 is repeated.

When the first measurement time TS14 has passed (YES determination in step S19), the average value of the detection results of the inclination detection unit 111 over the first measurement time TS14 is obtained as the descent operation end inclination L15 (step S20).

By the processing up to this point, the measurement of the lowering motion of the blocking rod 11a is completed, and then the measuring of the rising motion is started.

When the measurement of the rising motion is started, first, it is determined whether or not the detection result of the inclination detecting section 111 is below the rising start threshold value L13 (step S21). If it is equal to or greater than the rise start threshold value L13 (NO determination in step S21), the determination in step S21 is repeated so that the data generator 113 waits for the breaking rod 11a to rise.

When it is less than the rise start threshold value L13 (YES determination in step S21), the time measurement result is recorded by the time measurement unit 112 (step S22). Next, it is determined whether or not the detection result of the inclination detection unit 111 is below the rising end threshold value L14 (step S23). If the value is equal to or greater than the rise end threshold value L14 (NO determination in step S23), the determination in step S23 is repeated so that the data generator 113 waits for the breaking rod 11a to rise.

If it is less than the rising end threshold value L14 (YES determination in step S23), the rising operation time TS12 is obtained from the time measurement result of the time measuring unit 112 at this time and the time measurement result recorded in step S22 (step S24). ).

Note that the method of acquiring the rising operation time is similar to the method of acquiring the descending operation time described above. A method or the like of acquiring the elapsed time of as the rising operation time may be used.

Further, unlike the present embodiment, a timeout may be provided not only for obtaining the rising operation time but also for the operation time until the value falls below the rising end threshold value L14. That is, if the rise end threshold value L14 is not reached by the upper limit time, it may be determined that an abnormality such as the blocking rod 11a not being fully opened due to a fallen tree or the like has occurred, and the abnormality may be detected. In this case, when an abnormality is detected, the measurement process is stopped, and the detection result of the tilt detection unit 111 at the time of detection of the abnormality, the time measurement result of the time measurement unit 112, and error information indicating that an abnormality has occurred. and measurement data is generated. Then, the measured data is output to the main unit 13a without waiting for the output processing described later.

In the present embodiment, following acquisition of the rising operation time TS12, the data generator 113 determines whether or not the second waiting time TS15 has elapsed (step S25).

If the second waiting time TS15 has not elapsed (NO determination in step S25), the determination in step S25 is repeated so that the data generator 113 waits for the second waiting time TS15 to elapse. When the second waiting time TS15 has elapsed (YES determination in step S25), the detection result of the tilt detection unit 111 is recorded (step S26). Following this recording, the data generator 113 determines whether or not the second measurement time TS16 has elapsed (step S27). If the second measurement time TS16 has not elapsed (NO determination in step S27), the process returns to step S26, and the recording of the detection result by the tilt detection unit 111 is repeated.

When the second measurement time TS16 has elapsed (YES determination in step S27), the average value of the detection results of the slope detection unit 111 over the second measurement time TS16 is obtained as the rising operation end slope L16 (step S28).

When the measurement of the upward motion of the breaking rod 11a is completed as described above, measurement data representing the downward motion time TS11, the downward motion end slope L15, the upward motion time TS12, and the upward motion end slope L16 are generated and stored in a memory (not shown). It is stored (step S29). After that, the process returns to step S12 to enter a standby state in preparation for the next operation of the blocking rod 11a.

When the measurement data is generated and stored in this way, the output section 114 and the wireless communication section 115 follow the progress shown in the output chart TC162 in the blocking rod operation measurement chart TC16 in FIG. measurement data is output. First, the output unit 114 and the wireless communication unit 115 are in a standby state in which the communication board 104 is powered off until the end waiting time TS17 including the second measurement time TS16 elapses. When the end waiting time TS17 has elapsed, the power of the communication board 104 is turned on, and the output unit 114 and the wireless communication unit 115 enter a startup standby state. This activation standby state continues for a predetermined activation standby time TS18. After that, the output unit 114 reads out the measurement data from the memory and sends it to the main unit 13a in the railroad crossing equipment box 13 by wireless communication in the wireless communication unit 115 in accordance with a wireless communication standard such as Zigbee (registered trademark). output. After the output, it will be in a state of waiting for a response from the main unit 13a in the railroad crossing equipment box 13. FIG.

During this time, the main unit 13 a and the short-range wireless module 13 e in the railroad crossing equipment box 13 are waiting for measurement data from the blocking rod operation measuring device 100 . When receiving the measurement data from the blocking rod operation measuring device 100, the main unit 13a returns a response signal SR11 to the blocking rod operation measuring device 100 via the short-range wireless module 13e. In the output unit 114, when the response signal SR11 is received, the power of the communication board 104 is turned off after a predetermined end processing time TS19 has passed, and the communication board 104 returns to the standby state.

The processing executed by the output unit 114 regarding the output of such measurement data will be described with reference to the flow chart of FIG. 13, although it includes some overlap with the description so far.

The processing of this flowchart is started when the output unit 114 in the blocking rod operation measuring device 100 is activated after the sleep period defined by the sleep control unit 116 ends. Then, the output unit 114 is initialized (step S31), and then enters a standby state (step S32). This standby state (step S32) ends when the end waiting time TS17 described above elapses, and the process proceeds to the next step S33.

In step S33, the power of the communication board 104 is turned on to activate the wireless communication unit 115. Subsequently, the wireless communication unit 115 is initialized (step S34), and the output unit 114 and the wireless communication unit 115 are put into an activation standby state. . After that, the output unit 114 determines whether or not the startup standby time TS18 has elapsed (step S35). If the activation standby time TS18 has not elapsed (NO determination in step S35), the determination in step S35 is repeated to wait for the activation standby time TS18 to elapse. When the startup standby time TS18 has passed (YES determination in step S35), the output unit 114 reads the measurement data from the memory and outputs it to the main unit 13a by wireless communication via the wireless communication unit 115 (step S36).

Thereafter, the output section 114 determines whether or not the response signal SR11 has been returned from the main unit 13a within a predetermined time (step S37). If the response signal SR11 has not been returned (NO determination in step S37), the communication board 104 is powered off (step S38), and the output unit determines whether or not the measured data has been output three times. 114 (step S39). If the number of times has reached 3 (YES determination in step S39), the process returns to step S32, and the output unit 114 and the wireless communication unit 115 give up data output this time and prepare for the next operation of the gate. If it has not reached three times (NO determination in step S39), it is determined whether or not a predetermined delay time has elapsed (step S40). If the delay time has not elapsed (NO determination in step S40), the determination in step S40 is repeated to wait for the delay time to elapse. If the delay time has elapsed (YES determination in step S40), the process returns to step S33, and data output is retried by repeating the subsequent processes.

On the other hand, when the response signal SR11 is returned after the data output (YES determination in step S37), the output processing in the output unit 114 and the wireless communication unit 115 is completed (step S41), and the communication board 104 is turned off. It becomes OFF (step S42). After that, the process returns to step S32, and the output section 114 and the wireless communication section 115 prepare for the next operation of the gate.

In the circuit breaker 11, the breaking rod 11a is moved up and down by a driving portion 11b having a motor, a driving mechanism, etc., while being balanced by a balance weight attached to the rear end side of the breaking rod 11a. If the operation time and operation end inclination of the breaking rod 11a do not fall within a predetermined range, there is a possibility that the weight of the breaking rod 11a is shifted due to some kind of failure or breakage in the driving portion 11b. There is Abnormalities and symptoms such as the failure of the driving portion 11b and the deviation of the weight of the breaking rod 11a can be detected from the operation time and the operation end inclination of the breaking rod 11a. According to the blocking rod motion measuring device 100 of the above-described embodiment, the operation time required for each motion and the motion end inclination of the blocking rod 11a at the end of each motion are determined for the descending motion and the rising motion of the blocking rod 11a. The measurement data that represents is output to the output destination. In other words, since the measurement data that can be the source of abnormality judgment is output, the main unit 13a in the railroad crossing equipment box 13, which is the output destination, can capture not only the occurrence of abnormality but also the signs of abnormality using the measurement data. . In addition, abnormalities and signs thereof may appear separately when the blocking rod is lowered and when it is raised. On the other hand, according to the blocking rod operation measuring device 100 of the present embodiment, measurement data representing the operation time and the operation end inclination of each of the descending operation and the ascending operation are output. You can catch the signs without omission.

In addition, in this embodiment, the timekeeping function of the MPU 102f responsible for generating measurement data is used for timekeeping. That is, it is sufficient to prepare only the three-axis acceleration sensor 102a for detecting one type of physical quantity, namely the inclination of the blocking rod 11a, as a sensor as hardware. As described above, according to this embodiment, the number of sensors can be reduced, so that the cost of parts can be reduced.

Further, in the present embodiment, the resin case 100a, which is the housing of the blocking rod operation measuring device 100, is fixed to the mounting structure fixed to the driving portion 11b side of the blocking rod 11a. According to this configuration, compared with the case where the resin case 100a, that is, the blocking rod operation measuring device 100 is installed near the tip of the blocking rod 11a, the detection result of the inclination detection section 111 is more accurate than that of the blocking rod 11a. Since it is less likely to be affected by bending, shaking, etc., it is possible to improve the accuracy of measurement data based on this detection result. The method of attaching the resin case 100a to the breaking rod 11a, that is, the breaking rod operation measuring device 100, is not limited to the indirect method via the mounting structure as in the present embodiment, but directly to the breaking rod 11a. A fixing method or the like may be used.

Further, in the present embodiment, the tilt detector 111 detects the tilt of the blocking rod 11a using the three-axis acceleration sensor 102a. According to this configuration, the tilt of the breaking rod 11a can be detected with high precision by using the three-axis acceleration sensor 102a which is housed in the resin case 100a installed on the breaking rod 11a and moves together with the breaking rod 11a. Therefore, the accuracy of the measurement data can be further improved. Further, by using the three-axis acceleration sensor 102a, it is possible to detect, for example, twisting and positional deviation of the mounting state caused by loosening of the mounting portion of the three-axis acceleration sensor 102a. Furthermore, if breakage or the like occurs in the breaking rod 11a, an angle detection result in a direction that cannot occur in a normal state in which the breaking rod 11a extends straight can be obtained, and an event such as breakage can be detected with high accuracy. You can also

Moreover, in this embodiment, the output unit 114 wirelessly outputs the measurement data. According to this configuration, it is possible to output the measurement data to the main unit 13a in the railroad crossing equipment box 13, which is the output destination, even at the railroad crossing 1 where it is undesirable to route a long cable.

Further, in this embodiment, the resin case 100a is installed on the blocking rod 11a so that the longitudinal direction D11 of the rod-shaped antenna 105 is aligned with the longitudinal direction D12 of the blocking rod 11a. Then, the output unit 114 wirelessly outputs the measurement data via the wireless communication unit 115 when the breaking rod 11a is in a raised and standing state. According to this configuration, the rod-shaped antenna 105 with high communication performance is erected together with the blocking rod 11a, which serves as a metal shield, and there is no train, which tends to be a source of harmonic noise due to VVVF inverter control, and communication failure is prevented. Measurement data is wirelessly output when in the suppressed state. Therefore, the measurement data can be sent to the main unit 13a with high reliability. In addition, the risk of retrying when wireless output fails is also reduced, making it possible to suppress an increase in power consumption due to the implementation of retrying.

In addition, in the present embodiment, the data generator 113 generates measurement data representing the descending motion time TS11 and the ascending motion time TS12. The descent operation time TS11 is the operation time when the detection result of the inclination detection unit 111 changes from the descent start threshold value L11 to the descent end threshold value L12. This is the operation time when changing to the threshold value L14. According to this configuration, by comparing the detection result of the inclination detection unit 111 with each of the thresholds, the measurement data representing the operation time of the blocking rod 11a can be generated with high accuracy while suppressing the processing load. .

Further, in the present embodiment, the data generator 113 generates measurement data representing the descending motion end slope L15 and the ascending motion end slope L16. The descent operation end slope L15 is the average value of the detection results over the first measurement time TS14 after the first waiting time TS13 has passed after the detection result of the slope detection unit 111 reaches the descent end threshold value L12. The rise operation end slope L16 is the average value of the detection results over the second measurement time TS16 after the second waiting time TS15 has elapsed after the detection result reaches the rise end threshold value L14. According to this configuration, by generating the measurement data representing the average value of the detection results of the inclination detection unit 111 as the operation end inclination, the detection results are prevented from varying due to shaking of the blocking rod 11a at the end of the operation. stable measurement data can be obtained.

Further, in the present embodiment, when a predetermined sleep period arrives, sleep control is performed to stop the operations of the tilt detection unit 111, the timer unit 112, the data generation unit 113, the output unit 114, and the wireless communication unit 115 during the sleep period. A section 116 is provided. According to this configuration, it is possible to suppress power consumption during the sleep period, so that a power saving effect can be obtained.

It should be noted that the embodiments described above merely show typical forms of the present invention, and the present invention is not limited thereto. That is, various modifications can be made without departing from the gist of the present invention. Even with such a modification, as long as it still has the configuration of the blocking rod operation measuring device of the present invention, it is of course included in the scope of the present invention.

For example, in the above-described embodiment, as an example of the blocking rod operation measuring device, the measurement data is output to the main unit 13a in the railroad crossing equipment box 13, and the abnormality of the blocking rod 11a and its signs are entrusted to the main unit 13a. A rod motion measurement device 100 is illustrated. However, the blocking rod operation measuring device is not limited to this, and in addition to generating measurement data, it may also capture abnormalities and signs based on the measurement data, and output the capture results together with the measurement data. In addition, the acquisition of abnormalities and symptoms is not limited to being performed by either the blocking rod operation measuring device or the output destination of the measured data, but by both the blocking rod operation measuring device and the output destination. It may be done.

Here, as an example of a technique for detecting anomalies and symptoms, the following techniques are available. That is, there is a method of predetermining a determination range for each of a plurality of values, such as the operation time of the blocking rod 11a represented by the measurement data and the average value of the operation end inclination, and comparing each value. An example of the determination range is to provide a first range for capturing anomalies and a second range for capturing signs of anomalies set wider than the first range. In addition, regarding the determination, if any one of the multiple values represented by the measurement data is out of the determination range, it is determined that there is an abnormality in the circuit breaker, or a sign thereof is present. .

In addition, as described above, when an object is caught between the breaking rod 11a and the ground, or when the breaking rod 11a cannot be moved up or down completely due to a fallen tree or the like, it is possible to set a time-out for the breaker operating time. This is an example of a technique for capturing signs and symptoms. If the fall or rise threshold is not reached within this time, it will be detected as a switching fault.

Further, in the above-described embodiment, the body unit 13a in the railroad crossing equipment box 13 installed next to the alarm 12 is illustrated as an example of the output destination of the measurement data. However, the output destination of the measurement data is not limited to this.

Further, in the above-described embodiment, the blocking rod operation measuring device 100 is illustrated in which the resin case 100a, which is a housing, is installed near the drive portion 11b of the blocking rod 11a via a mounting structure. However, the blocking rod operation measuring device is not limited to this, and the installation location of the housing may be any location including the tip of the blocking rod. However, as described above, the accuracy of the measurement data based on the detection results can be improved by arranging the housing closer to the driving section 11b in the blocking rod 11a.

Further, in the above-described embodiment, the blocking rod motion measuring device 100 including the tilt detection unit 111 that detects the tilt of the blocking rod 11a using the triaxial acceleration sensor 102a is illustrated. However, this does not matter as to the specific sensor mode of the tilt detection section. For example, an acceleration sensor other than three-axis may be used, and an angle sensor such as an optical or magnetic encoder may be used. However, with the encoder or the like, detailed individual adjustment and individual setting are required at the time of installation, and detection is only possible in the operating direction of the crossing gate. , it is advantageous in that it enables detection in directions other than the movement direction. Furthermore, by using the three-axis acceleration sensor 102a, it is possible to detect torsion in the mounting state, positional deviation, etc., and it is possible to detect events such as breakage of the breaking rod 11a with high precision as described above. be.

Moreover, in the above-described embodiment, the blocking rod operation measuring device 100 in which the output unit 114 wirelessly outputs the measurement data is exemplified. However, the blocking rod operation measuring device is not limited to this, and for example, measurement data may be output by wire. However, as described above, wireless output also enables output at railroad crossing 1 where a long cable is undesirable.

In the above-described embodiment, the resin case 100a, which is a housing, is installed so that the rod-shaped antenna 105 is along the blocking rod 11a, and the measurement data is transmitted wirelessly when the blocking rod 11a is raised and erected. An output blocking rod operation measuring device 100 is illustrated. However, the blocking rod operation measuring device is not limited to this, and the housing may be installed in any posture with respect to the blocking rod. It may be output. However, when the blocking rod 11a is in an upright state, i.e., when the train is absent, wireless output from the rod-shaped antenna 105 provided along the blocking rod 11a enables measurement data to be transmitted to the main unit with high reliability. The point that it can be sent to the unit 13a is also as described above. Also, as described above, this makes it possible to suppress an increase in power consumption due to the execution of retries.

In the above-described embodiment, the data generation unit 113 compares the detection result of the inclination detection unit 111 with various threshold values to generate measurement data representing the descending operation time TS11 and the ascending operation time TS12. Apparatus 100 is illustrated. However, the blocking rod operation measuring device is not limited to this, and it is possible to arbitrarily set what kind of time and what method to obtain as the operating time of the blocking rod. However, by comparing the detection result of the inclination detection unit 111 with each of the above thresholds, it is possible to generate measurement data representing the operation time of the blocking rod 11a with high accuracy while suppressing the processing load. Street.

Further, in the above-described embodiment, the data generation unit 113 calculates the average value of the detection results over a predetermined measurement time, thereby generating measurement data representing the descent operation end slope L15 and the rise operation end slope L16. A measurement device 100 is illustrated. However, the blocking rod operation measuring device is not limited to this, and it is possible to arbitrarily set what kind of value and what kind of method are obtained as the movement end inclination of the blocking rod. However, as described above, stable measurement data can be obtained by obtaining the average value as described above.

Moreover, in the above-described embodiment, the blocking rod operation measuring device 100 provided with the sleep control section 116 is exemplified. However, the blocking rod operation measuring device is not limited to this. For example, the sleep control section may not be provided, and processing such as tilt detection, measurement data generation, and data output may be performed all the time. However, as described above, the power saving effect can be obtained by providing the sleep control unit.

Further, in the above-described embodiment, the device for measuring the operation of the barrier rod 11a in the railroad crossing gate 11 is used, but the measurement target is not limited to the railroad crossing gate. For example, it may be applied to gate barriers for toll roads and toll parking lots. In this way, for circuit breakers that require regular inspection work by maintenance personnel, the load of inspection and maintenance work can be reduced when the number of items to be inspected is enormous or when the location is difficult to enter. be. Further, by automatically acquiring the measurement data and transmitting it to the command server, changes in the data can be grasped one by one, and an effect of predicting and preventing failure can be obtained.
