It is a figure showing an example of measuring device 10 which is one embodiment of the present invention. 3 is a diagram showing details of a microcomputer 21. FIG. 3 is a flowchart for explaining the operation of a microcomputer 21.

At least the following matters will become apparent from the description of this specification and the accompanying drawings.
FIG. 1 is a diagram showing a configuration of a measuring apparatus 10 according to an embodiment of the present invention. The measuring device 10 is a device that measures the wetting time based on the temperature and humidity around the steel tower 100 provided in the power system. Here, the wetting time is, for example, a time when the temperature is 0 ° C. or higher and the humidity is 80% or higher.

  The measuring device 10 includes a sensor 20, a microcomputer 21, an electromagnetic counter 22, a battery 30, and a power supply circuit 31.

  The sensor 20 (measuring device) is a sensor that measures the temperature and humidity around the steel tower 100. Further, the sensor 20 converts the measured temperature and humidity into digital data based on an instruction from the microcomputer 21 and outputs the digital data to the microcomputer 21.

  Based on the output from the sensor 20, the microcomputer 21 (determination device) has a predetermined time T1 (for example, 1 hour) as the accumulated time TA of the time when the temperature is 0 ° C. or higher and the humidity is 80% or higher. It is repeatedly determined whether or not. Specifically, when the microcomputer 21 determines that the accumulated time TA becomes the predetermined time T1, the microcomputer 21 initializes the accumulated time TA (for example, the accumulated time TA is zero), and the accumulated time TA becomes the predetermined time T1 again. It is determined whether or not. Further, the microcomputer 21 increments the count value CNT1 of the electromagnetic counter 22 when the accumulated time TA reaches the predetermined time T1. Details of the microcomputer 21 will be described later.

  The electromagnetic counter 22 (storage device) is a counter that mechanically updates and displays the count value CNT1 in accordance with an instruction from the microcomputer 21. Note that the electromagnetic counter 22 continues to hold the count value CNT1 when there is no instruction from the microcomputer 21, and thus operates as a storage device that stores the count value CNT1.

  The battery 30 is a battery for operating the measuring apparatus 10, and the power supply circuit 31 generates a predetermined power supply for operating the sensor 20 and the microcomputer 21.

== Details of the microcomputer 21 ==
Here, the details of the microcomputer 21 will be described with reference to FIG. The microcomputer 21 includes a timer 50, a memory 51, and a CPU 52.

  The timer 50 (timer) starts measuring time when power is supplied to the microcomputer 21. The memory 51 stores program data executed by the CPU 52 and various data.

  The CPU 52 implements various functional blocks by executing the program data stored in the memory 51. Specifically, the CPU 52 implements determination units 60 and 62, a counter 61, a control unit 63, and an activation unit 64.

  The determination unit 60 (first determination unit) acquires the output from the sensor 20 every predetermined time T2 shorter than the predetermined time T1, and determines whether the temperature is 0 ° C. or higher and the humidity is 80% or higher. Determine. The time T2 is assumed to be a sufficiently short time (for example, 6 minutes) such that changes in temperature and humidity around the steel tower 100 can be ignored.

  The counter 61 (storage unit) increments the count value CNT2 every time the determination unit 60 determines that the temperature is 0 ° C. or higher and the humidity is 80% or higher. Therefore, when the count value CNT2 increases by “1”, the time when the temperature is 0 ° C. or more and the humidity is 80% or more is increased by the predetermined time T2. Thus, the counter 61 accumulates the time T2 and stores it as the accumulated time TA.

  The determination unit 62 (second determination unit) determines that the accumulated time TA becomes the predetermined time T1 when the count value CNT2 of the counter 61 reaches the predetermined value indicating the predetermined time T1, and the count value of the counter 61 Reset CNT2. In the present embodiment, the predetermined value is determined such that the product (T2 × predetermined value) of the predetermined time T2 and the predetermined value is the predetermined time T1.

  When it is determined that the cumulative time TA becomes the predetermined time T1, the control unit 63 increments the count value CNT1 of the electromagnetic counter 22. Further, when power is supplied to the microcomputer 21, the control unit 63 increments the count value CNT1 in order to make the user determine whether the electromagnetic counter 22 operates normally.

  The starting unit 64 repeatedly starts and stops the determination units 60 and 62 every predetermined time T2 based on the output of the timer 50. Specifically, the activation unit 64 causes the determination units 60 and 62 to execute the above-described determination process when the determination units 60 and 62 are activated. In addition, when the determination process described above is executed, the activation unit 64 stops the operation of the determination units 60 and 62 so that the current consumed by the determination units 60 and 62 becomes substantially zero. The activation unit 64 temporarily stops the determination units 60 and 62 when detecting that the timer 50 has been activated.

== Operation of the microcomputer 21 ==
Here, the operation of the microcomputer 21 will be described with reference to FIG. First, when power is supplied to the microcomputer 21 and the microcomputer 21 is activated, the control unit 63 increments the count value CNT1 in order to determine whether the operation of the electromagnetic counter 22 operates normally. (S100). Then, the timer 50 is activated to start timing (S101), and the activation unit 64 stops the determination units 60 and 62 (S102). Thereafter, the activation unit 64 determines whether or not the predetermined time T2 has elapsed based on the time measurement result of the timer 50 (S103). The starting unit 64 continues to stop the determination units 60 and 62 until the predetermined time T2 elapses after the determination units 60 and 62 are stopped (S103: NO). On the other hand, the activation unit 64 activates the determination units 60 and 62 when the predetermined time T2 has elapsed since the determination units 60 and 62 were stopped (S103: YES) (S104).

  The determination unit 60 acquires the output from the sensor 20, and determines whether the temperature is 0 ° C. or higher and the humidity is 80% or higher (S105). When the determination unit 60 determines that the temperature is 0 ° C. or higher and the humidity is not 80% or higher (S105: NO), the process S102 is executed. On the other hand, when the determination unit 60 determines that the temperature is 0 ° C. or higher and the humidity is 80% or higher (S105: YES), the counter 61 increments the count value CNT2 (S106). Then, the determination unit 62 determines whether or not the count value CNT2 is a predetermined value, that is, whether or not the accumulated time TA is equal to the predetermined time T1 (S107). When the count value CNT2 is not the predetermined value, that is, when the accumulated time TA is not the predetermined time T1 (S107: NO), the process S102 is executed. On the other hand, when the count value CNT2 becomes the predetermined value, that is, when the accumulated time TA becomes the predetermined time T1 (S107: YES), the control unit 63 increments the count value CNT1 of the electromagnetic counter 22 (S108), and the determination The unit 62 resets the count value CNT2 of the counter 61 (S109). Thereafter, the process 102 is executed again. As described above, the microcomputer 21 of the present embodiment continues to increment the count value CNT1 of the electromagnetic counter 22 every time the accumulation time TA of the wetting time reaches the predetermined time T1. Incidentally, as described above, in the present embodiment, the count value CNT1 is incremented to determine whether the electromagnetic counter 22 operates normally when the measuring apparatus 10 is started. Therefore, the total amount of wetting time since the measurement device 10 is started is represented by the product of the value obtained by subtracting “1” from the count value CNT1 and the predetermined time T1.

  The measurement apparatus 10 according to the present embodiment has been described above. For example, when a lightning strike occurs on the steel tower 100, the microcomputer 21 may be destroyed. However, the electromagnetic counter 22 mechanically stores the number of times the wetting time becomes the predetermined time T1. Therefore, in the present embodiment, it is possible to prevent the wetting time stored in the electromagnetic counter 22 from being lost even if a lightning strike occurs.

  Moreover, the microcomputer 21 acquires the output from the sensor 20 every predetermined time T2, and determines whether the temperature is 0 ° C. or higher and the humidity is 80% or higher. For this reason, for example, the power consumption of the microcomputer 21 can be reduced as compared with the case where the output from the sensor 20 is continuously acquired and the determination is made as to whether the temperature is 0 ° C. or higher.

  Moreover, since the starting part 64 repeats starting and a stop of the determination parts 60 and 62 every predetermined time T2, the power consumption of the microcomputer 21 can be reduced.

  For example, the electromagnetic counter 22 may be incremented every predetermined time T2 shorter than the predetermined time T1, but in that case, the number of times the count value of the electromagnetic counter 22 is updated increases. In general, when the case where the count value CNT2 of the counter 61 in the microcomputer 21 is incremented is compared with the case where the count value CNT1 of the electromagnetic counter 22 is incremented, the latter consumes more power. In the present embodiment, the count value CNT1 of the electromagnetic counter 22 is not incremented every predetermined time T2, but the count value CNT2 of the counter 61 is incremented. Therefore, an increase in power consumption of the microcomputer 21 can be suppressed even when the temperature or the like is measured at short intervals of the predetermined time T2.

  In general, it is difficult to secure a commercial power source or the like for operating the measuring device 10 around the steel tower 100. Since the measuring device 10 of this embodiment is operated by the battery 30, the measuring device 10 can be installed regardless of the surrounding environment of the steel tower 100.

  For example, when only the number of times the cumulative time TA of the wetting time becomes the predetermined time T1 is stored, a general mechanical counter may be used. In that case, a device for changing the count value of the mechanical counter based on the output of the microcomputer 21 is required. However, since the electromagnetic counter 22 is used in this embodiment, the number of parts can be reduced.

  The microcomputer 21 increments the count value CNT1 of the electromagnetic counter 22 when power is supplied. For this reason, for example, when the measuring apparatus 10 is installed, it can be confirmed whether or not the electromagnetic counter 22 operates normally. In the present embodiment, the count value CNT1 is incremented, but may be decremented after the increment, for example. That is, the count value CNT1 may be changed so that it can be confirmed whether or not the electromagnetic counter 22 operates normally.

  The above-described embodiment is intended to facilitate understanding of the present invention, and is not intended to limit the present invention. The present invention is changed and improved without departing from the gist thereof, and the present invention includes equivalents thereof.
