Embodiment for Carrying Out the Invention

[0020] <Alarm sound measuring device 100> Figure 1 shows a warning sound measuring device 100 according to one embodiment of the present invention. The warning sound measuring device 100 includes a control unit 110, a sound pressure detection unit 120, a storage unit 130, and a communication unit 140. The warning sound measuring device 100 measures the warning sound of a railroad crossing and transmits the measured values ​​of the railroad crossing warning sound (for example, measured values ​​of the sound pressure and ringing cycle of the warning sound) to an external device 200.

[0021] The alarm sound measuring device 100 is installed for each level crossing device 300 of the level crossing, for example, as shown in Figure 2. In the example shown in Figure 2, the level crossing has two level crossing devices 300-1 and 300-2, which are installed on either side of the railway track 400. The alarm sound measuring device 100-1 is installed on level crossing device 300-1 to measure the physical quantity of the alarm sound generated by the alarm sound generator 310-1 of level crossing device 300-1, and the alarm sound measuring device 100-2 is installed on level crossing device 300-2 to measure the physical quantity of the alarm sound generated by the alarm sound generator 310-2 of level crossing device 300-2. The external device 200 is installed near level crossing device 300-1.

[0022] The control unit 110 is an information processing device (computer) for processing information, and for example, it has an MPU. The sound pressure detection unit 120 is a device for detecting the sound pressure of an alarm sound, and for example, it is composed of a sound pressure sensor and a detection circuit. The storage unit 130 is a storage device (for example, memory) for storing information. The communication unit 140 is a communication device for transmitting information, and for example, it performs wireless communication (for example, wireless communication using a short-range communication standard (for example, ZigBee® standard)).

[0023] Figure 3 shows an example of the control unit 110. The control unit 110 includes a measurement processing unit 111 and a transmission processing unit 112.

[0024] The measurement processing unit 111 measures the physical quantities of the level crossing alarm sound based on the sound pressure of the alarm sound detected by the sound pressure detection unit 120, and stores the measured values ​​in the storage unit 130. As part of measuring the physical quantities of the alarm sound, the measurement processing unit 111 measures, for example, the sound pressure value of the alarm sound (e.g., peak sound pressure value) and the alarm sounding period.

[0025] At this time, the measurement processing unit 111 measures the physical quantity of the warning sound for each level crossing operation. Here, the level crossing operation is a series of operations of the level crossing device 300 from the start of the warning sound and the illumination of the warning lights to the end of the warning sound and illumination of the warning lights. As shown in Figure 4, some level crossing warning sounds decrease in volume after the level crossing gates close. In this case, it is preferable for the measurement processing unit 111 to measure the physical quantity of the warning sound when it is attenuated, in addition to measuring the physical quantity of the warning sound under normal conditions.

[0026] The transmission processing unit 112 transmits the measured values ​​stored in the storage unit 130 to the external device 200 using communication via the communication unit 140. At this time, the transmission processing unit 112 transmits measurement information, which is a compilation of the measured values ​​of the physical quantity of the alarm sound for a predetermined number of level crossing operations, to the external device 200 for each of the predetermined number of level crossing operations.

[0027] The measurement information transmitted by the transmission processing unit 112 includes level crossing operation identification information, which is information for identifying the level crossing operation for which the measured value included in the measurement information was measured. The level crossing operation identification information may include, for example, time related to the level crossing operation (for example, the time when the alarm sound measuring device 100 started measuring the physical quantity of the level crossing operation, or the time when the measured value was stored in the storage unit 130).

[0028] Furthermore, if a level crossing includes multiple level crossing devices 300, and a warning sound measuring device 100 is installed for each level crossing device 300, it is preferable that the measurement information transmitted by the transmission processing unit 112 also includes measuring device identification information, which is information for identifying the warning sound measuring device 100 that measured the measurement value included in the measurement information.

[0029] Figure 5 shows an example of measurement information transmitted by the alarm sound measuring devices 100-1 and 100-2 shown in Figure 2. In the example shown in Figure 5, the transmission processing unit 112 of the control unit 110 of the alarm sound measuring devices 100-1 and 100-2 transmits measurement information summarizing the measured values ​​of the physical quantity of the alarm sound for three level crossing operations to an external device 200 for each of the three level crossing operations. Figure 5 shows an example of measurement information summarizing the measured values ​​of the physical quantity of the alarm sound for three level crossing operations (level crossing operations 1 to 3). The upper part of Figure 5 shows the measurement information summarizing the measured values ​​of the physical quantity of the alarm sound for level crossing operations 1 to 3 from the alarm sound measuring device 100-1, and the lower part of Figure 5 shows the measurement information summarizing the measured values ​​of the physical quantity of the alarm sound for level crossing operations 1 to 3 from the alarm sound measuring device 100-2. In the example shown in Figure 5, the measurement information for level crossing operations 1 to 3 includes the time the measurement started (X111, X121, X131, X211, X221, X231) as level crossing operation identification information, the IDs of the alarm sound measuring devices 100-1 and 100-2 (X112, X122, X132, X212, X222, X232) as measurement device identification information, and the peak sound pressure values ​​of the alarm sound (X113, X123, X133, X213, X223, X233) and the alarm sound period (X114, X124, X134, X214, X224, X234) as physical quantities of the alarm sound. If there are normal and reduced sound conditions, the peak sound pressure values ​​and alarm periods for each may also be included. In level crossing operation 1, alarm sound measuring device 100-1 collects measured values ​​of alarm sounds from X111 to X114, and alarm sound measuring device 100-2 collects measured values ​​of alarm sounds from X211 to X214, and stores them in the storage unit 130. By performing this until a predetermined number of times is reached (3 times in one example), alarm sound measuring device 100-1 generates a data matrix of X111 to X134, and alarm sound measuring device 100-2 generates a data matrix of X211 to X234 as measurement information.

[0030] As described above, in this embodiment, measurement information summarizing the measured values ​​of the physical quantity of the alarm sound for a predetermined number of level crossing operations is transmitted to an external device 200 for each of the predetermined number of level crossing operations. Therefore, in this embodiment, the number of times measurement information is transmitted is reduced, making it possible to suppress the power consumption of the alarm sound measuring device 100. As a result, in this embodiment, if the alarm sound measuring device 100 is powered by a battery, it is possible to reduce the consumption of the battery.

[0031] Figure 6 shows an example of the processing operations performed by the control unit 110 when the transmission processing unit 112 transmits measurement information, which summarizes the measured values ​​of the physical quantity of the alarm sound for N times (where N is a natural number greater than or equal to 2), to an external device for each of the N level crossing operations. The processing operations shown in Figure 6 are performed for each of the N level crossing operations.

[0032] The measurement processing unit 111 measures the physical quantity of the alarm sound (step S601). Until the measurement of the physical quantity of the alarm sound for the Nth level crossing operation is completed (step S602, NO), the measurement processing unit 111 measures the physical quantity of the alarm sound for each level crossing operation and stores the measured value in the storage unit 130 (step S601). Once the measurement of the physical quantity of the alarm sound for the Nth level crossing operation is completed (step S602, YES), the measurement information summarizing the measured values ​​of the physical quantity of the alarm sound for the N level crossing operations is transmitted to an external device (step S603).

[0033] <Timing of sending measurement information> The transmission processing unit 112 is configured to transmit the measurement information for a predetermined number of level crossing operations only after all of the predetermined number of level crossing operations to be transmitted together (i.e., all of the predetermined number of level crossing operations to be included in the measurement information) have been completed. By doing so, the measurement information will be transmitted after the train has passed the level crossing, making it possible to transmit the measurement information without interference from train radio communication.

[0034] In this case, the control unit 110 may further include a termination detection processing unit 113. The termination detection processing unit 113 detects the end of the alarm sound after all of the processing by the measurement processing unit 111 (measurement processing for the predetermined number of level crossing operations and storage processing of the measured values ​​in the storage unit 130) for a predetermined number of level crossing operations for which the measured values ​​of the physical quantity of the alarm sound are compiled into measurement information has been completed. Then, the transmission processing unit 112 may transmit the measurement information for the predetermined number of level crossing operations using communication by the communication unit 140 after the termination detection processing unit 113 has detected the end of the alarm sound. In other words, the transmission processing unit 112 may transmit the measurement information for the predetermined number of level crossing operations when all of the predetermined number of level crossing operations that are transmitted together (i.e., all of the predetermined number of level crossing operations that are compiled into measurement information) have been completed. By doing so, it becomes possible to transmit the measurement information immediately after the level crossing operations are completed.

[0035] The termination detection processing unit 113 detects the end of the alarm sound based, for example, on the sound pressure of the alarm sound detected by the sound pressure detection unit 120. At this time, the termination detection processing unit 113 determines that the alarm sound has ended when, for example, the sound pressure of the alarm sound detected by the sound pressure detection unit 120 falls below a first sound pressure value (that is, when the sound pressure value falls from a value equal to or greater than the first sound pressure value to a value less than the first sound pressure value).

[0036] Furthermore, in order to further reduce the power consumption of the alarm sound measuring device 100, the alarm sound measuring device 100 may further include an alarm sound detection unit 150, and the control unit 110 of the alarm sound measuring device 100 may further include a pause processing unit 114 and a start processing unit 115.

[0037] The alarm sound detection unit 150 is a device for detecting alarm sounds and, for example, has a vibration power generation element that generates electricity by vibrations in the frequency range of the alarm sound (for example, 700 to 750 Hz). If the voltage of the power generated by the vibration power generation element is equal to or greater than a first voltage value, the unit determines that an alarm sound has been detected and outputs a signal (for example, a High signal) to the control unit 110 indicating that an alarm sound has been detected. If the voltage of the power generated by the vibration power generation element is less than the first voltage value, the unit determines that an alarm sound has not been detected and outputs a signal (for example, a Low signal) to the control unit 110 indicating that an alarm sound has not been detected.

[0038] The pause processing unit 114 puts the control unit 110 into a pause state if, when the processing of the measurement processing unit 111 is completed, all of the processing of the measurement processing unit 111 for a predetermined number of level crossing operations for which the measured values ​​of the physical quantity of the alarm sound are included in the measurement information containing the measured values ​​from that processing has not been completed. In other words, if the number of level crossing operations has not reached a predetermined number (less than N level crossing operations and measurement processing in Figure 6), the control unit 110 is put into a pause state after the measurement and storage processing of the measurement processing unit 111 is completed until the next level crossing operation is started. The pause processing unit 114 also puts the control unit 110 into a pause state after the transmission processing by the transmission processing unit 112 is completed. In other words, the pause processing unit 114 puts the control unit 110 into a pause state when processing by the measurement processing unit 111 is completed during level crossing operations in which measurement information is not transmitted by the transmission processing unit 112 (i.e., when the number of level crossing operations has not reached a predetermined number), and puts the control unit 110 into a pause state when processing by the transmission processing unit 112 is completed during level crossing operations in which measurement information is transmitted by the transmission processing unit 112 (i.e., when the number of level crossing operations has reached a predetermined number). Here, the pause state is a state in which power consumption is reduced by reducing the amount of processing that can be executed compared to the normal state, and includes, for example, a STOP mode that stops the clock signal, an IDLE mode that stops the supply of the clock signal, and a HALT mode that stops the execution of instructions.

[0039] If the alarm sound detection unit 150 detects an alarm sound while the control unit 110 is in a paused state, the start processing unit 115 will return the control unit 110 from the paused state to the normal state (i.e., terminate the paused state of the control unit 110). For example, if the alarm sound detection unit 150 receives a signal (e.g., a High signal) indicating that an alarm sound has been detected while the control unit 110 is in a paused state, the start processing unit 115 will return the control unit 110 from the paused state to the normal state.

[0040] Then, when the resting state of the control unit 110 ends, the measurement processing unit 111 starts measuring the physical quantities of the alarm sound (for example, measuring the sound pressure value of the alarm sound (for example, the peak sound pressure value) and the alarm sounding period).

[0041] In this way, in level crossing operations where measurement information is not transmitted, the control unit 110 enters a dormant state from the end of the alarm sound measurement process until the end of the level crossing alarm sound, thereby suppressing power consumption in the alarm sound measuring device 100.

[0042] Furthermore, once the control unit 110 has obtained the necessary measurement values ​​for physical quantities such as the sound pressure and ringing period of the alarm sound in the measurement processing unit 111, it may execute the processing of the measurement processing unit 111 (measurement processing and storage processing of measurement values ​​in the storage unit 130) and then transition to a pause state. For example, a level crossing continues to ring until a train passes, and no significant fluctuations occur in sound pressure or ringing period while the level crossing is in operation. Therefore, by ending the measurement and transitioning to a pause state as soon as the necessary physical quantities are obtained during the operation of the level crossing, it is not necessary to operate the alarm sound measuring device 100 during the operation of the level crossing. In cases where the level crossing is installed in a location where the operation of the level crossing continues for a long time, such as a so-called "level crossing that is always closed" in an urban area, it is possible to suppress the power consumption of the alarm sound measuring device 100 by acquiring measurement values ​​immediately after the start of the operation of the level crossing and then transitioning to a pause state.

[0043] Figure 7 is an example of a time chart showing the state changes of the control unit 110 and communication unit 140 of the alarm sound measuring device 100. Figure 7 is an example of a time chart when the transmission processing unit 112 transmits measurement information, which summarizes the measured values ​​of the physical quantity of the alarm sound for three level crossing operations, to an external device 200 after each of the three level crossing operations. In the example shown in Figure 7, the transmission processing unit 112 uses communication by the communication unit 140 to transmit measurement information, which summarizes the measured values ​​of the alarm sound for three level crossing operations (level crossing operations 1 to 3), to the external device 200 after the three level crossing operations (level crossing operations 1 to 3) have finished.

[0044] When the alarm sound for level crossing operation 1 starts at t=t1, the start processing unit 115 terminates the pause state of the control unit 110 and returns the control unit 110 to the normal state, the measurement processing unit 111 starts measuring the physical quantity of the alarm sound, and at t=t2, after the processing for level crossing operation 1 by the measurement processing unit 111 (measurement processing of the alarm sound of level crossing operation 1 and storage processing of the measured value in the storage unit 130) is completed, the pause processing unit 114 returns the control unit 110 from the normal state to the pause state.

[0045] When the alarm sound for level crossing operation 2 starts at t=t3, the start processing unit 115 terminates the pause state of the control unit 110 and returns the control unit 110 to the normal state, the measurement processing unit 111 starts measuring the physical quantity of the alarm sound, and at t=t4, after the processing for level crossing operation 2 by the measurement processing unit 111 (measurement processing of the alarm sound of level crossing operation 2 and storage processing of the measured value in the storage unit 130) is completed, the pause processing unit 114 returns the control unit 110 from the normal state to the pause state.

[0046] When the alarm sound for level crossing operation 3 starts at t=t5, the start processing unit 115 terminates the pause state of the control unit 110 and returns the control unit 110 to the normal state, and the measurement processing unit 111 starts measuring the physical quantity of the alarm sound. At t=t6, after the measurement processing unit 111 has finished processing level crossing operation 3 (measurement processing of the alarm sound for level crossing operation 3 and storage processing of the measured value in the storage unit 130), the control unit 110 enters a standby state, and the termination detection processing unit 113 starts detecting the end of the alarm sound. At t=t7, when the termination detection processing unit 113 detects the end of the alarm sound, the transmission processing unit 112 uses the communication unit 140 to transmit measurement information summarizing the measured values ​​of the physical quantities of the alarm sounds for level crossing operations 1 to 3 to an external device 200. At t=t8, when the transmission processing by the transmission processing unit 112 is completed, the pause processing unit 114 returns the control unit 110 from the standby state to the pause state.

[0047] Furthermore, the transmission processing unit 112 may transmit the measurement information using communication via the communication unit 140 when it detects the alarm sound for the next level crossing operation following a predetermined number of level crossing operations for which the measurement values ​​are compiled into the measurement information. In other words, the transmission processing unit 112 may transmit the measurement information for a predetermined number of level crossing operations when the next level crossing operation following a predetermined number of level crossing operations that are to be transmitted together begins. In this case, the pause processing unit 114 may put the control unit 110 into a pause state after the processing of the measurement processing unit 111 is completed.

[0048] When the alarm sound is detected, it is at the beginning of the alarm sound, the level crossing gates are not yet closed, and the train has not yet reached the level crossing. Therefore, by doing so, it is possible to transmit measurement information without interference from train radio communications. In addition, by doing so, it becomes unnecessary to detect the end of the alarm sound (end of the level crossing operation), and the control unit 110 can be put into a dormant state when processing is not being performed by the measurement processing unit 111. As a result, it becomes possible to further reduce the power consumption of the alarm sound measuring device 100.

[0049] Figure 8 is an example of a time chart showing the state changes of the control unit 110 and communication unit 140 of the alarm sound measuring device 100. Figure 8 is an example of a time chart when the transmission processing unit 112 transmits measurement information, which summarizes the measured values ​​of the physical quantity of the alarm sound for three level crossing operations, to an external device 200 for each of the three level crossing operations. In the example shown in Figure 8, the transmission processing unit 112 uses communication by the communication unit 140 to transmit measurement information, which summarizes the measured values ​​of the physical quantity of the alarm sound for three level crossing operations (level crossing operations 1 to 3), to the external device 200 when the next level crossing operation 4, following the three level crossing operations (level crossing road operations 1 to 3), begins. Figure 8 is a time chart from the start of level crossing operation 4, which follows level crossing operations 1 to 3, to the end of level crossing operation 7, which is the next level crossing operation after the next level crossing operation 4.

[0050] When the alarm sound for level crossing operation 4 starts at t=t1, the start processing unit 115 terminates the pause state of the control unit 110 and returns the control unit 110 to the normal state, the measurement processing unit 111 starts measuring the physical quantity of the alarm sound, and the transmission processing unit 112 uses the communication unit 140 to transmit measurement information summarizing the measured values ​​of the physical quantities of the alarm sounds for level crossing operations 1 to 3 to an external device 200. At t=t2, after the processing for level crossing operation 4 by the measurement processing unit 111 (measurement processing of the alarm sound for level crossing operation 4 and storage processing of the measured values ​​in the storage unit 130) is completed, the pause processing unit 114 returns the control unit 110 from the normal state to the pause state.

[0051] When the alarm sound for the level crossing operation 5 starts at t=t3, the start processing unit 115 terminates the pause state of the control unit 110 and returns the control unit 110 to the normal state, the measurement processing unit 111 starts measuring the physical quantity of the alarm sound, and at t=t4, after the processing for the level crossing operation 5 by the measurement processing unit 111 (measurement processing of the alarm sound of the level crossing operation 5 and storage processing of the measured value in the storage unit 130) is completed, the pause processing unit 114 returns the control unit 110 from the normal state to the pause state.

[0052] When the alarm sound for the level crossing operation 6 starts at t=t5, the start processing unit 115 terminates the pause state of the control unit 110 and returns the control unit 110 to the normal state, the measurement processing unit 111 starts measuring the physical quantity of the alarm sound, and at t=t6, after the processing for the level crossing operation 6 by the measurement processing unit 111 (measurement processing of the alarm sound of the level crossing operation 6 and storage processing of the measured value in the storage unit 130) is completed, the pause processing unit 114 returns the control unit 110 from the normal state to the pause state.

[0053] When the alarm sound for level crossing operation 7 starts at t=t7, the start processing unit 115 terminates the pause state of the control unit 110 and returns the control unit 110 to the normal state, the measurement processing unit 111 starts measuring the physical quantity of the alarm sound, and the transmission processing unit 112 uses the communication unit 140 to transmit measurement information summarizing the measured values ​​of the physical quantities of the alarm sounds for level crossing operations 4-6 to an external device 200. At t=t8, after the processing for level crossing operation 7 by the measurement processing unit 111 (measurement processing of the alarm sound for level crossing operation 7 and storage processing of the measured values ​​in the storage unit 130) is completed, the pause processing unit 114 returns the control unit 110 from the normal state to the pause state.

[0054] <Processing when an abnormality is detected in the measurement value> The alarm sound measuring device 100 should transmit abnormality information, including the abnormal measurement value, if it detects an abnormality in the measurement value of the physical quantity of the alarm sound. In this way, it is possible to notify the external device 200 that an abnormality has been detected in the measurement value of the physical quantity of the alarm sound. An abnormality here refers to cases where the sound pressure of the alarm sound is above or below a predetermined sound pressure (sound is too quiet / too loud), or the alarm sound is not sounding (speaker is disconnected), or the period of the alarm sounding is longer / shorter than a predetermined cycle, or is not intermittent, etc., where the alarm sound deviates from the allowable value or specified value and exhibits behavior different from a normal railroad crossing alarm sound.

[0055] For example, the termination detection processing unit 113 may be configured to detect the end of the alarm sound if an abnormality is detected in the measured value of the alarm sound. Then, the transmission processing unit 112 may be configured to transmit abnormality information to an external device 200 using communication via the communication unit 140 once the termination detection processing unit 113 has detected the end of the alarm sound. At this time, the pause processing unit 114 puts the control unit 110 into a pause state from the normal state not after the processing by the measurement processing unit 111 when the abnormally detected measured value was measured (the alarm sound measurement process and the storage process of the measured value in the storage unit 130), but after the transmission of abnormality information by the transmission processing unit 112 has finished. By doing so, it becomes possible to notify the external device 200 more quickly that an abnormality has been detected in the measured value of the physical quantity of the alarm sound.

[0056] The transmission processing unit 112 may also transmit recovery information, which includes information indicating that the measured value has recovered to a normal value, if the measurement processing by the measurement processing unit 111 after an abnormality has been detected in the measured value of the alarm sound becomes normal. In this way, it becomes possible to notify the external device 200 that the measured value of the physical quantity of the alarm sound has recovered to a normal value.

[0057] In this case, the termination detection processing unit 113 may detect the end of the alarm sound if the measured value of the alarm sound becomes normal during the measurement processing by the measurement processing unit 111 after an abnormality has been detected in the measured value of the alarm sound. If the measured value of the alarm sound becomes normal during the measurement processing by the measurement processing unit 111 after an abnormality has been detected in the measured value of the alarm sound, the transmission processing unit 112 may transmit recovery information using communication by the communication unit 140 after the termination detection processing unit 113 has detected the end of the alarm sound. Furthermore, if the measured value of the alarm sound becomes normal during the measurement processing by the measurement processing unit 111 after an abnormality has been detected in the measured value of the alarm sound, the pause processing unit 114 will put the control unit 110 from the normal state to the pause state not after the processing by the measurement processing unit 111 when the normal measured value was measured (the alarm sound measurement processing and the storage processing of the measured value to the storage unit 130), but after the transmission of recovery information by the transmission processing unit 112 has finished. By doing so, it becomes possible to notify the external device 200 more quickly that the measured value of the physical quantity of the alarm sound has recovered to a normal value.

[0058] Figure 9 is an example of a time chart showing the state changes of the control unit 110 and communication unit 140 of the alarm sound measuring device 100. Figure 9 is an example of a time chart when the transmission processing unit 112 transmits measurement information, which summarizes the measured values ​​of the physical quantity of the alarm sound for three level crossing operations, to an external device 200 for each of the three level crossing operations. In the example shown in Figure 9, the transmission processing unit 112 uses communication by the communication unit 140 to transmit measurement information, which summarizes the measured values ​​of the alarm sound for three level crossing operations (level crossing operations 1 to 3), to the external device 200 after the three level crossing operations (level crossing operations 1 to 3) have finished. Also, Figure 9 is a time chart when an abnormality is detected in the measured value of the physical quantity of the alarm sound for level crossing operation 2. In the example shown in Figure 9, the abnormality information is transmitted to the external device 200 after level crossing operation 2 has finished.

[0059] When the alarm sound for level crossing operation 1 starts at t=t1, the start processing unit 115 terminates the pause state of the control unit 110 and returns the control unit 110 to the normal state, the measurement processing unit 111 starts measuring the physical quantity of the alarm sound, and at t=t2, after the processing for level crossing operation 1 by the measurement processing unit 111 (measurement processing of the alarm sound of level crossing operation 1 and storage processing of the measured value in the storage unit 130) is completed, the pause processing unit 114 returns the control unit 110 from the normal state to the pause state.

[0060] When the alarm sound for level crossing operation 2 starts at t=t3, the start processing unit 115 terminates the pause state of the control unit 110 and returns the control unit 110 to the normal state, and the measurement processing unit 111 starts measuring the physical quantity of the alarm sound. At t=t4, after the measurement processing unit 111 has finished processing for level crossing operation 2 (measurement processing of the alarm sound for level crossing operation 2 and storage processing of the measured value in the storage unit 130), the control unit 110 enters a standby state, and the termination detection processing unit 113 starts detecting the end of the alarm sound. At t=t5, when the termination detection processing unit 113 detects the end of the alarm sound, the transmission processing unit 112 transmits abnormal information to an external device 200 using communication via the communication unit 140. At t=t6, when the transmission processing by the transmission processing unit 112 is completed, the pause processing unit 114 returns the control unit 110 from the standby state to the pause state.

[0061] When the alarm sound for level crossing operation 3 starts at t=t7, the start processing unit 115 terminates the pause state of the control unit 110 and returns the control unit 110 to the normal state, and the measurement processing unit 111 starts measuring the physical quantity of the alarm sound. At t=t8, after the measurement processing unit 111 finishes processing for level crossing operation 3 (measurement processing of the alarm sound for level crossing operation 3 and storage processing of the measured value in the storage unit 130), the control unit 110 enters a standby state, and the termination detection processing unit 113 starts detecting the end of the alarm sound. At t=t9, when the termination detection processing unit 113 detects the end of the alarm sound, the transmission processing unit 112 uses the communication unit 140 to transmit measurement information summarizing the measured values ​​of the physical quantities of the alarm sounds for level crossing operations 1 to 3 to an external device 200. At t=t10, when the transmission processing by the transmission processing unit 112 is completed, the pause processing unit 114 returns the control unit 110 from the standby state to the pause state.

[0062] <Transmission at a predetermined time or at predetermined time intervals> The transmission processing unit 112 may also transmit measurement information, which summarizes the measured values ​​of the physical quantities of the alarm sounds of multiple level crossing operations, to an external device 200 at a predetermined time. Doing so also reduces the number of times measurement information is transmitted, making it possible to suppress the power consumption of the alarm sound measuring device 100.

[0063] Furthermore, the transmission processing unit 112 may also transmit measurement information, which summarizes the measured values ​​of the physical quantity of the alarm sound of the level crossing operation during a predetermined time interval, to an external device 200 at each predetermined time interval. Doing so also reduces the number of times measurement information is transmitted, making it possible to suppress the power consumption of the alarm sound measuring device 100.

Although the present invention has been described with reference to specific examples, various modifications and changes can be made to these examples without departing from the spirit and scope of the invention as described in the claims.
