Description

The present invention relates to a barrier rod operation measuring device that measures the operation of a barrier rod in a barrier such as a railroad crossing.

Conventionally, there is known a technique for measuring the operation of a barrier rod in order to capture the presence or absence of an abnormality in a railroad crossing barrier (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 determination standard, and the determination result is a higher-level management device. Will be notified to.

JP-A-2017-105336

Here, in the barrier, some signs may appear before the abnormality actually occurs. However, since the above-mentioned technique only notifies the determination result as to whether or not there is an abnormality, it must be said that it is difficult to catch the sign at the notification destination prior to the occurrence of the abnormality.

Therefore, an object of the present invention is to pay attention to the above circumstances and to provide a barrier rod operation measuring device capable of catching not only the occurrence of an abnormality but also a sign of an abnormality in the barrier at the notification destination.

In order to solve the above problem, the blocking rod motion measuring device is a blocking rod motion measuring device that measures the operation of the blocking rod in the breaking machine, and has a tilt detecting unit for detecting the tilt of the blocking rod and a time. The time measuring unit to be measured, the operation time required for each operation for the descent operation and the ascending operation of the cutoff rod, and the measurement data indicating the operation end inclination of the cutoff rod at the end of each operation are obtained by the inclination detection unit. A data generation unit that is generated based on the detection result in the above and the timekeeping result in the timekeeping unit, an output unit that outputs the measurement data to a predetermined output destination, the inclination detection unit, the timekeeping unit, and the data generation unit. , And a housing for accommodating the output unit, the housing is installed so as to move together with the blocking rod, and the tilt detecting unit uses an acceleration sensor or an angle sensor to mount the blocking rod. It is characterized by detecting the inclination of.

Generally, in a barrier, the barrier rod is moved up and down by a drive unit having a motor, a drive mechanism, or the like while being balanced by a balance weight attached to the rear end side of the barrier rod. If the operating time and the end inclination of the blocking rod do not fall within the predetermined range, there is a possibility that some kind of failure in the drive unit or the weight of the blocking rod is deviated due to breakage or the like. The following abnormalities and signs are events that can be captured from the operation time of the cutoff rod and the inclination of the end of operation, such as a failure of the drive unit and a deviation in the weight of the cutoff rod. According to the above-mentioned blocking rod operation measuring device, measurement data indicating the operation time required for each operation and the operation end inclination of the blocking rod at the end of each operation is output to the descent operation and the ascending operation of the blocking rod. Is output to. That is, since the measurement data that can be the source of the abnormality judgment is output, not only the occurrence of the abnormality but also the sign of the abnormality can be captured by using the measurement data at the output destination. In addition, abnormalities and their signs may appear individually 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 indicating the operation time and the operation end inclination of each of the descent operation and the ascending operation is output, so that the abnormalities and signs appearing individually as described above are leaked. Can be caught without.

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

Further, according to the above-mentioned blocking rod motion measuring device, the inclination of the blocking rod is detected with high accuracy by using an acceleration sensor or an angle sensor housed in a housing and provided so as to move together with the blocking rod. Therefore, the accuracy of the measurement data can be further improved.

It is also preferable that the output unit wirelessly outputs the measurement data.

According to this configuration, the measurement data can be output to a desired output destination even at a railroad crossing where it is not desirable for the cable to be arranged for a long time.

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

According to this configuration, the measurement data is output wirelessly when the rod-shaped antenna having high communication performance is erected together with the blocking rod and the communication failure is suppressed. Therefore, the measurement data is desired with high reliability. Can be sent to the output destination of. Communication failure is suppressed when the rod-shaped antenna is erected together with the blocking rod. When the blocking rod is erected, that is, when the blocking rod is raised, a metal shield called a train is used between the rod-shaped antenna and the output destination. This is because it does not exist in between. Further, in recent trains, motor control by VVVF inverter control (Variable Voltage Variable Frequency) is often adopted. When the train passes, the harmonic noise generated by the VVVF inverter control is likely to be radiated from the train, but when the train is absent, the communication failure due to the harmonic noise is also suppressed. By wirelessly outputting the measurement data in such a state, the risk of retries when the wireless output fails, for example, can be reduced, and it is possible to suppress an increase in power consumption due to the execution of retries.

Further, the data generation unit has a descent operation time measured by the timekeeping unit when the detection result of the inclination detection unit changes from the descent start threshold to the descent end threshold, and a detection result of the inclination detection unit. It is also preferable to generate measurement data representing the ascending operation time timed by the timekeeping unit as the operating time when is changing from the ascending start threshold to the ascending end threshold.

According to this configuration, the measurement data representing the operating time of the blocking rod can be generated with high accuracy while suppressing the processing load by comparing the detection result of the inclination detection unit with each of the above threshold values.

In addition, the data generation unit is an average value of the detection results of the inclination detection unit over the first measurement time after the first waiting time elapses after the detection result of the inclination detection unit reaches the descent end threshold. , And the average value of the detection results of the inclination detection unit over the second measurement time after the second waiting time elapses after the detection result of the inclination detection unit reaches the rise end threshold. It is also preferable to generate measurement data expressed as.

According to this configuration, by generating measurement data that represents the average value of the detection results in the tilt detection unit as the operation end inclination, the detection results may vary due to the shaking of the blocking rod at the end of the operation. However, stable measurement data can be obtained.

Further, when a predetermined sleep period arrives, it is also preferable to further include a sleep control unit that stops the operation of the tilt detection unit, the timekeeping unit, the data generation unit, and the output unit during the sleep period. ..

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

According to the above-mentioned blocking rod operation measuring device, not only the occurrence of an abnormality but also the sign of the abnormality of the barrier can be detected at the notification destination.

After that, after waiting for the train to pass, the end of the sounding of the alarm sound after the passage, the start of ascending of the blocking rod 11a, and the end of ascending are indicated. After the ascending of the blocking rod 11a is completed, the measurement result is output from the blocking rod operation measuring device 100 to the main body unit 13a after the measurement by the blocking rod operation measuring device 100 is completed, as will be described later.

The breaker chart TC14 shows a change in the inclination of the breaker rod 11a in the breaker 11. The blocking rod 11a, which stands vertically when the train is absent and has a tilt angle of 0 °, descends toward a horizontal state where the tilt angle becomes 90 ° when the descent standby time elapses after the start of the alarm sound. Start. When the tilt angle reaches 90 ° in the predetermined descent time, the train waits for passage, and when the train passes and the alarm sound ends, the ascent starts. The operation of the blocking rod 11a ends when the tilt angle becomes 0 ° vertically in a predetermined rising time.

Here, the excessively abrupt descent and ascent movement of the blocking rod 11a may hit a pedestrian crossing the railroad crossing 1, a pedestrian standing in front of the railroad crossing 1, or catch a pedestrian's clothes. It may bring about a situation. Further, if the blocking rod 11a is lowered or climbed too slowly, the blocking time of the road R12 passing through the railroad crossing 1 becomes long, which may cause traffic congestion. Therefore, the above-mentioned descent time and ascending time are appropriately determined in consideration of pedestrian safety, traffic conditions, the structure of the barrier 11, and the like.

The main unit chart TC15 shows a communication event performed from the main unit 13a to the blocking rod operation measuring device 100 according to a communication standard such as Zigbee (registered trademark). In the present embodiment, the communication event performed from the main unit 13a to the blocking rod motion measuring device 100 is only a notification of receipt confirmation of the measurement data output from the blocking rod motion measuring device 100.

The cutoff rod operation measurement chart TC16 shows a measurement chart TC161 and an output chart TC162.

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

First, the data generation unit 113 obtains the descent operation time TS11 measured by the timekeeping 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. Further, when the detection result of the inclination detection unit 111 changes from the ascending start threshold value L13 to the ascending end threshold value L14, the ascending operation time TS12 timed by the timing unit 112 is obtained. Here, the descent start threshold value L11 is an inclination angle when the blocking rod 11a is tilted to a predetermined degree from a state in which the blocking rod 11a is erected vertically (0 °), and the descent end threshold value L12 is that the blocking rod 11a is horizontal. It is the tilt angle at a stage before a predetermined degree of tilting to (90 °). As the descent start threshold value L11, for example, an angle such as 5 ° is given as an example, and as the descent end threshold value L12, an angle such as 85 ° or the like is given as an example. Further, the ascending start threshold value L13 is an inclination angle when the blocking rod 11a rises to a predetermined degree from a state where the blocking rod 11a is tilted horizontally (90 °), and the ascending end threshold value L14 is that the blocking rod 11a is vertical (0). It is the tilt angle at the stage before a certain amount of rise to °). As the ascending start threshold value L13, for example, an angle of 85 ° or the like can be mentioned as an example, and as the ascending end threshold value L14, for example, an angle of 5 ° or the like can be mentioned as an example. The specific values of the descent start threshold value L11, the descent end threshold value L12, the ascending start threshold value L13, and the ascending end threshold value L14 can be arbitrarily set according to, for example, the detection resolution in the inclination detection unit 111. ..

Further, in the data generation unit 113, the detection result of the tilt detection unit 111 over the first measurement time TS14 after the first waiting time TS13 elapses after the detection result of the tilt detection unit 111 reaches the descent end threshold value L12. The average value of 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 elapses after the detection result of the tilt detection unit 111 reaches the rise end threshold value L14 increases. It is obtained as the end slope L16.

Then, the data generation unit 113 generates measurement data representing the descent operation time TS11, the ascending operation time TS12, the descent operation end inclination L15, and the ascending operation end inclination L16 obtained in this way.

The process related to the generation of such measurement data will be described with reference to the flowcharts of FIGS. 11 and 12, although the contents slightly overlap with the above description.

The processing of this flowchart is started when the cutoff rod operation measuring device 100 is activated after the sleep period defined by the sleep control unit 116 is completed. Then, first, the initialization of each element is performed (step S11), and then the standby state is set (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 the descent start threshold value is less than L11 (NO determination in step S13), the process returns to step S12 and the standby state is set.

When the descent start threshold value L11 is exceeded (YES determination in step S13), the timekeeping result is recorded in the timekeeping 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). When the descent end threshold value is less than L12 (NO determination in step S15), the determination in step S15 is repeated, so that the data generation unit 113 is in a state of waiting for descent of the blocking rod 11a.

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

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

Further, unlike the present embodiment, a time-out may be provided not only for the acquisition of 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 the pinching of an object such as a vehicle between the blocking rod 11a and the ground has occurred. As a result, the abnormality may be detected. In this case, when an abnormality is detected, the process is stopped, the detection result by the tilt detection unit 111 at the time of abnormality detection, the time measurement result by the time measurement unit 112, and the error information indicating that the abnormality has occurred. Measurement data representing, is generated. Then, the measurement data is output to the main unit 13a without waiting for the output process described later.

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

When the first waiting time TS13 has not elapsed (NO determination in step S17), the determination in step S17 is repeated, so that the data generation unit 113 is in the elapsed waiting state of the first waiting time TS13. When the first waiting time TS13 has elapsed (YES determination in step S17), the detection result by the tilt detection unit 111 is recorded (step S18). Following this recording, the data generation unit 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 inclination detection unit 111 is repeated.

When the first measurement time TS14 has elapsed (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).

With the processing up to this point, the measurement regarding the descent operation of the blocking rod 11a is completed, and then the measurement proceeds to the ascending operation.

When shifting to the measurement of the ascending motion, first, it is determined whether or not the detection result by the tilt detecting unit 111 is below the ascending start threshold value L13 (step S21). When the rise start threshold value L13 or more (NO determination in step S21), the determination in step S21 is repeated, so that the data generation unit 113 is in a state of waiting for the rise of the blocking rod 11a.

When the rise start threshold value L13 is exceeded (YES determination in step S21), the timekeeping result is recorded in the timekeeping unit 112 (step S22). Next, it is determined whether or not the detection result of the inclination detection unit 111 is below the rise end threshold value L14 (step S23). When the rise end threshold value L14 or more (NO determination in step S23), the determination in step S23 is repeated, so that the data generation unit 113 is in a state of waiting for the rise of the blocking rod 11a.

When the rise end threshold value L14 is exceeded (YES determination in step S23), the rise operation time TS12 is obtained from the time measurement result in the time measurement unit 112 at this point and the time measurement result recorded in step S22 (step S24). ).

As in the method of acquiring the ascending operation time, the method of acquiring the ascending operation time is also the same as the method of acquiring the descending operation time described above. It may be a method or the like to acquire the elapsed time of the above as an ascending operation time.

Further, unlike the present embodiment, a time-out may be provided not only for the acquisition of the ascending operation time but also for the operating time until the ascending end threshold value L14 is exceeded. That is, if the rise end threshold value L14 is not exceeded by the upper limit time, it may be assumed that an abnormality such as the blocking rod 11a not being completely 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, the detection result of the tilt detection unit 111 at the time of abnormality detection, the time measurement result of the timing unit 112, and error information indicating that the abnormality has occurred. And, the measurement data representing is generated. Then, the measurement data is output to the main unit 13a without waiting for the output process described later.

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

When the second waiting time TS15 has not elapsed (NO determination in step S25), the determination in step S25 is repeated, so that the data generation unit 113 is in the elapsed waiting state of the second waiting time TS15. When the second waiting time TS15 has elapsed (YES determination in step S25), the detection result by the tilt detection unit 111 is recorded (step S26). Following this recording, the data generation unit 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 inclination 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 inclination detection unit 111 over the second measurement time TS16 is obtained as the ascending operation end inclination L16 (step S28).

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

When the measurement data is generated and stored in this way, the output unit 114 and the wireless communication unit 115 follow the process as shown in the output chart TC162 in the cutoff rod operation measurement chart TC16 of FIG. The 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 turned off until the end waiting time TS17 including the second measurement time TS16 elapses. When the end waiting time TS17 elapses, the power of the communication board 104 is turned on, and the output unit 114 and the wireless communication unit 115 are in the start-up standby state. This start-up standby state is continued for a predetermined start-up wait time TS18. After that, the output unit 114 reads the measurement data from the above memory and directs the measurement data to the main unit 13a in the railroad crossing equipment box 13 by wireless communication in the wireless communication unit 115 conforming to a wireless communication standard such as Zigbee (registered trademark). And output. After the output, the state waits for a response from the main body unit 13a in the railroad crossing equipment box 13.

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

The process executed by the output unit 114 regarding the output of such measurement data will be described with reference to the flowchart of FIG. 13, although the contents slightly overlap with the description so far.

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

In step S33, the power of the communication board 104 is turned on, the wireless communication unit 115 is activated, the wireless communication unit 115 is subsequently initialized (step S34), and the output unit 114 and the wireless communication unit 115 are in the activation standby state. .. After that, the output unit 114 determines whether or not the start-up standby time TS18 has elapsed (step S35). If the start-up waiting time TS18 has not elapsed (NO determination in step S35), the determination in step S35 is repeated, so that the start-up standby time TS18 is in an elapsed waiting state. When the start-up standby time TS18 has elapsed (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).

After that, the output unit 114 determines whether or not the response signal SR11 has been returned from the main unit 13a within a predetermined time (step S37). When the response signal SR11 is not returned (NO determination in step S37), the power of the communication board 104 is turned off (step S38), and the output unit determines whether or not the number of times the measurement data has been output has reached three. It is performed in 114 (step S39). When it reaches three times (YES determination in step S39), the process returns to step S32, and the output unit 114 and the wireless communication unit 115 give up the data output this time and prepare for the operation of the next breaker. If the number of times has not reached three (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, so that the delay time is in a waiting state. When the delay time has elapsed (YES determination in step S40), the process returns to step S33, and the subsequent processes are repeated to retry the data output.

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 powered by the power supply. It is turned off (step S42). After that, the process returns to step S32, and the output unit 114 and the wireless communication unit 115 prepare for the operation of the next breaker.

In the breaker 11, the breaker 11a is moved up and down by a drive unit 11b having a motor, a drive mechanism, and the like, while being balanced by a balance weight attached to the rear end side of the breaker 11a. If the operation time and operation end inclination of the blocking rod 11a do not fall within the predetermined range, there is a possibility that some kind of failure in the drive unit 11b or the weight of the blocking rod 11a is displaced due to breakage or the like. There is. Abnormalities and signs such as a failure of the drive unit 11b and a deviation in the weight of the blocking rod 11a can be captured from the operating time of the blocking rod 11a and the operation end inclination. According to the cutoff rod operation measuring device 100 of the above-described embodiment, regarding the descent operation and the ascending operation of the cutoff rod 11a, the operation time required for each operation and the operation end inclination of the cutoff rod 11a at the end of each operation are determined. The represented measurement data is output to the output destination. That is, since the measurement data that can be the source of the abnormality judgment is output, the main body unit 13a in the railroad crossing equipment box 13 that is the output destination can capture not only the occurrence of the abnormality but also the sign of the abnormality by using the measurement data. .. In addition, abnormalities and their signs may appear individually when the blocking rod is lowered and when it is raised. On the other hand, according to the cutoff rod operation measuring device 100 of the present embodiment, measurement data indicating the operation time and the operation end inclination of each of the descent operation and the ascending operation is output. You can catch all the signs.

Further, in the present embodiment, the timekeeping function of the MPU 102f, which is responsible for generating measurement data, is used for timekeeping. That is, as the sensor as hardware, it is sufficient to prepare only the triaxial acceleration sensor 102a that detects one kind of physical quantity called the inclination of the blocking rod 11a. As described above, according to the present embodiment, since the number of sensors can be reduced, the component cost 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 near the drive unit 11b in the blocking rod 11a. According to this configuration, as 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 by the tilt detecting unit 111 is that of the blocking rod 11a. Since it is not easily affected by bending and shaking, the accuracy of measurement data based on this detection result can be improved. The method of attaching the resin case 100a to the blocking rod 11a, that is, the blocking rod operation measuring device 100 is not limited to the indirect method via the mounting structure as in the present embodiment, but is directly attached to the blocking rod 11a. It may be a fixing method or the like.

Further, in the present embodiment, the inclination detection unit 111 detects the inclination of the blocking rod 11a by using the triaxial acceleration sensor 102a. According to this configuration, the inclination of the blocking rod 11a can be detected with high accuracy by using the triaxial acceleration sensor 102a housed in the resin case 100a installed on the blocking rod 11a and moving together with the blocking rod 11a. Therefore, the accuracy of the measurement data can be further improved. Further, by using the triaxial acceleration sensor 102a, for example, it is possible to detect twisting, misalignment, etc. of the mounting state caused by loosening of the mounting portion of the triaxial acceleration sensor 102a. Further, when the blocking rod 11a is broken, for example, an angle detection result in a direction that cannot occur when the blocking rod 11a is extended straight can be obtained, and an event such as a break can be detected with high accuracy. You can also do it.

Further, in the present embodiment, the output unit 114 wirelessly outputs the measurement data. According to this configuration, even at the railroad crossing 1 where it is not desirable that the cable is arranged for a long time, the measurement data can be output to the main body unit 13a in the railroad crossing equipment box 13 which is the output destination.

Further, in the present 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 along 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 blocking rod 11a is in the raised and upright state. According to this configuration, a rod-shaped antenna 105 having high communication performance is erected together with a blocking rod 11a to serve as a metal shield, and there is no train that tends to generate harmonic noise due to VVVF inverter control, resulting in communication failure. The measurement data is output wirelessly when it is in a suppressed state. Therefore, the measurement data can be sent to the main unit 13a with high reliability. In addition, the risk of retries when the wireless output fails is also reduced, and it is possible to suppress an increase in power consumption due to the execution of retries.

Further, in the present embodiment, the data generation unit 113 generates measurement data representing the descent operation time TS11 and the ascending operation time TS12. The descent operation time TS11 is the operation time when the detection result by the tilt detection unit 111 changes from the descent start threshold value L11 to the descent end threshold value L12, and the ascending operation time TS12 is the ascending operation time TS12 when the detection result is ascended from the ascending start threshold value L13. This is the operation time when the threshold value is changed to L14. According to this configuration, by comparing the detection result of the tilt detection unit 111 with each of the above threshold values, measurement data representing the operating time of the blocking rod 11a can be generated with high accuracy while suppressing the processing load. ..

Further, in the present embodiment, the data generation unit 113 generates measurement data representing the descent operation end inclination L15 and the ascent operation end inclination L16. The descent operation end inclination L15 is an average value of the detection results over the first measurement time TS14 after the first waiting time TS13 elapses after the detection result by the inclination detection unit 111 reaches the descent end threshold value L12. The ascending operation end inclination L16 is an average value of the detection results over the second measurement time TS16 after the second waiting time TS15 elapses after the detection result reaches the ascending end threshold value L14. According to this configuration, by generating measurement data representing the average value of the detection results of the tilt detection unit 111 as the operation end inclination, the detection results may vary due to the shaking of the blocking rod 11a at the end of the operation. Even if there is, stable measurement data can be obtained.

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

It should be noted that the embodiments described above merely show typical embodiments of the present invention, and the present invention is not limited thereto. That is, it can be modified in various ways without departing from the gist of the present invention. As long as the structure of the blocking rod operation measuring device of the present invention is still provided by such deformation, it is, of course, included in the category of the present invention.

For example, in the above-described embodiment, as an example of the blocking rod operation measuring device, measurement data is output to the main body unit 13a in the crossing instrument box 13, and the capture of an abnormality or a sign of the blocking rod 11a is entrusted to the main body unit 13a. The rod motion measuring device 100 is illustrated. However, the blocking rod operation measuring device is not limited to this, and in addition to generating the measurement data, it may also capture abnormalities and signs based on the measurement data and output the capture result together with the measurement data. In addition, the capture of abnormalities and signs is not limited to one of the blocking rod motion measuring device and the output destination of the measurement data, but both the blocking rod motion measuring device and the output destination. You may do it.

Here, as an example of the method of capturing an abnormality or a sign, the following method can be mentioned. That is, there is a method in which a determination range is set in advance 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 the values are compared with each value. As an example of the determination range, a first range for capturing an abnormality and a second range for capturing signs of abnormality set wider than the first range are provided as an example. As an example of the determination, if any one of the plurality of values represented by the measurement data is out of the determination range, it is determined that the breaker is abnormal or a sign thereof appears. ..

Further, as described above, it is also abnormal to set a time-out for the operation time of the barrier for abnormality detection such as the blocking rod 11a being caught between the blocking rod 11a and the ground, the blocking rod 11a not being able to move up and down completely due to a fallen tree, or the like. It is given as an example of a method for capturing signs and signs. If the descent or rise threshold is not reached within this time, it will be detected as an open / close abnormality.

Further, in the above-described embodiment, as an example of the output destination of the measurement data, the main body unit 13a in the railroad crossing equipment box 13 installed next to the alarm 12 is exemplified. However, the output destination of the measurement data is not limited to this, and for example, a command server connected via a predetermined network may be set as the output destination and directly output to this command server.

Further, in the above-described embodiment, the blocking rod operation measuring device 100 in which the resin case 100a, which is a housing, is installed near the drive unit 11b in the blocking rod 11a via a mounting structure is exemplified. 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 result can be improved by installing the housing closer to the drive unit 11b in the blocking rod 11a.

Further, in the above-described embodiment, the blocking rod operation measuring device 100 including the tilt detecting unit 111 for detecting the tilt of the blocking rod 11a using the triaxial acceleration sensor 102a is exemplified. However, this is not a question about the specific sensor mode in the tilt detection unit. For example, an acceleration sensor other than the three axes may be used, or an angle sensor such as an optical or magnetic encoder may be used. However, with an encoder or the like, it takes time and effort for detailed individual adjustment and individual setting at the time of installation, and only detection can be performed in the operating direction of the breaker. It is advantageous in that it can be detected in a direction other than the operating direction. Further, by using the triaxial acceleration sensor 102a, it is possible to detect twisting, misalignment, etc. in the mounted state, and it is possible to detect events such as breakage of the blocking rod 11a with high accuracy, as described above. be.

Further, 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 cutoff rod operation measuring device is not limited to this, and for example, the measurement data may be output by wire. However, as described above, it is possible to output even at the railroad crossing 1 where it is not desirable that the cable is arranged for a long time by outputting wirelessly.

Further, 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 wirelessly transmitted when the blocking rod 11a is in a raised and erected state. The cutoff rod operation measuring device 100 to output is exemplified. 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, and the measurement data is wirelessly transmitted when the blocking rod 11a is in the lowered state. It may be output. However, the measurement data can be obtained with high reliability by wirelessly outputting from the rod-shaped antenna 105 provided along the blocking rod 11a when the blocking rod 11a is in an upright state, that is, when the train is absent. The point that it can be sent to the unit 13a is also as described above. Further, as described above, this makes it possible to suppress an increase in power consumption due to the execution of the retry.

Further, in the above-described embodiment, the data generation unit 113 generates measurement data representing the descent operation time TS11 and the ascending operation time TS12 by comparing the detection result of the inclination detection unit 111 with various threshold values. Device 100 is illustrated. However, the blocking rod operation measuring device is not limited to this, and what kind of time is obtained as the operating time of the blocking rod can be arbitrarily set by what method. However, as described above, the measurement data representing the operating time of the blocking rod 11a is generated with high accuracy while suppressing the processing load by comparing the detection result of the tilt detecting unit 111 with each of the above threshold values. It's a street.

Further, in the above-described embodiment, the data generation unit 113 generates measurement data representing the descent operation end inclination L15 and the ascent operation end inclination L16 by obtaining the average value of the detection results over a predetermined measurement time. The measuring device 100 is illustrated. However, the cutoff rod operation measuring device is not limited to this, and what kind of value is obtained as the operation end inclination of the cutoff rod by what method can be arbitrarily set. However, as described above, stable measurement data can be obtained by obtaining the average value as described above.

Further, in the above-described embodiment, the cutoff rod operation measuring device 100 provided with the sleep control unit 116 is exemplified. However, the cutoff rod operation measuring device is not limited to this, and may be configured to constantly perform processing such as tilt detection, measurement data generation, and data output without providing, for example, a sleep control unit.
