  Hereinafter, the safety monitoring system according to the present embodiment will be described with reference to the drawings. In the following description, components having substantially the same function and configuration are given the same reference numerals, and repeated description will be made only when necessary.

  As shown in FIG. 1, the safety watching system has a safety watching server device 11. The server device 11 is connected to the Internet network 13. Connected to the Internet network 13 are a smart meter management server device 17 of a power company that manages the smart meter 12, a portable information processing terminal 29 such as a smartphone, and an information processing terminal 31 of a security company. Furthermore, a plurality of battery-type communication devices 23 and 24 are connected to the Internet network 13 via the gateway device 21. The gateway device 21 and the battery-type communication devices 23 and 24 are wirelessly connected as a short distance wireless communication standard typically under the Bluetooth (registered trademark) standard.

  The plurality of battery-type communication devices 23 and 24 stored in the television remote control etc. in the target household watching safety are not limited to the form connected to the Internet network 13 via the gateway device 21. The battery-type communication devices 23 and 24 May be directly connected to the Internet network 13, or the battery type communication devices 23, 24 may be connected to the Internet network 13 via a portable information processing device of a smartphone owned by the watching target. May be

  The battery-type communication devices 23, 24 have a shape and a size conforming to the battery standard, and are housed in the battery box of the battery-driven devices 25, 26 provided with the manual operation unit. It is preferable that the battery-powered devices 25 and 26 have essentially different operation frequencies. As the battery-powered devices 25 and 26, for example, a battery remote control system having a relatively high frequency of operation in one day, and a battery ignition type gas range in which a relatively regular operation is assumed although the frequency of operation of the television remote control is low. It is illustrated.

  The battery-type communication devices 23, 24 have a shape and a size according to the battery standard. The battery-type communication device 23 is configured as, for example, an AA, and the battery-type communication device 24 is configured as, for example, a single type. The shape, size, etc. of the battery-type communication devices 23, 24 are arbitrary according to the battery-driven devices 25, 26.

  As shown in FIG. 2, the battery-type communication device 23 has a cylindrical housing 41 having a height and a diameter conforming to AA battery standards. The outer positive electrode terminal 43 and the outer negative electrode terminal 44 are attached to the front and rear end surfaces of the housing 41 in accordance with AA battery standards. Inside the housing 41, a battery storage portion 42 for storing a smaller standard AAA battery (internal battery) is provided. The inner positive terminal 45 and the inner negative terminal 46 connected to the positive and negative terminals of the storage battery of the battery storage portion 42 are connected to the outer positive terminal 43 and the outer negative terminal 44 respectively.

  The battery housing 42 is radially offset with respect to the cylinder center axis of the housing 41. This offset secures a small space inside the housing 41. An electronic circuit board 47 for realizing various functions of the battery-type communication device 23 is accommodated in this small space. The circumferential surface portion of the housing 41 opposite to the electronic circuit board 47 is cut in an oval shape. The length of the notch is equal to or slightly shorter than that of the AAA battery, and the width is slightly larger than that of the AAA battery. As a result, the AAA internal battery can be inserted into and removed from the battery storage unit 42 through the notch.

  FIG. 3 is an equivalent circuit diagram of an electronic circuit mounted on the electronic circuit board 47 of the battery type communication device 23. As shown in FIG. The inner positive electrode terminal 45 and the outer positive electrode terminal 43 are electrically connected, and the inner negative electrode terminal 46 and the outer negative electrode terminal 44 are also electrically connected. When a manual operation button such as a channel of the television remote control 25 is pressed, the internal current value of the electronic circuit board 47, here, the current value between the inner negative electrode terminal 46 and the outer negative electrode terminal 44 fluctuates according to the load fluctuation. In order to detect the internal current, a detection resistor 401 is provided to convert the internal current into a voltage. The voltage across the detection resistor 401 (detection voltage) is applied to the input terminal (inversion input terminal) of the comparator 407. The positive electrode voltage of the internal battery 48 is divided by the voltage dividing resistors 402 and 403 and applied as a reference voltage to the other input terminal (non-inverted input terminal) of the comparator 407. The comparator 407 compares the detected voltage with the reference voltage. When a manual operation button such as a channel of the television remote control 25 is pressed, the detected voltage fluctuates. The voltage dividing resistors 402 and 403 are adjusted so as to detect that the comparison result of the comparator 407 is changed according to the fluctuation of the detection voltage and the manual operation button is pressed. The DCDC converter 404 generates the power supply voltage Vdd of the comparator 407 and the RFIC 405 using the battery voltage of the internal battery 48 stored in the battery storage unit 42. When it is detected from the comparison result of the comparator 407 that a manual operation button such as the channel of the television remote control 25 has been pressed, the RFIC 405 identifies the battery type communication device 23 with an identification number (hereinafter referred to as battery type communication device ID). Operation data including a time code indicating a time when the television remote control 25 is operated is transmitted to the gateway device 21 through the antenna 406. The operation data is transmitted from the gateway device 21 to the safety monitoring server device 11 via the Internet 13.

  The distribution board 14 installed in the house of the watching target household is connected to the pole transformer TR via the smart meter 12. The distribution board 14 is equipped with a master breaker 16 and a plurality of branch breakers 18. The smart meter 12 periodically measures the power consumption data of the target household, for example, every 30 minutes, and transmits it together with a time code. The power consumption data is transmitted to the safety monitoring server 11 directly from the smart meter 12 or via the smart meter management server 17 of the power company.

  FIG. 4 shows functional blocks of the safety monitoring server device 11. In addition, a program for causing the safety monitoring server device 11 to realize these functions (means) as a computer is installed.

  Operation data reception unit 115, power consumption data reception unit 117, storage unit 113 for storing operation data, power consumption data, etc. centering on control unit 111, timer unit 119 for measuring elapsed time, reset of timer unit 119, etc. The timer control unit 121 controls the operation of the power consumption variation calculation unit 123, the safety confirmation condition determination unit 125, and an alarm signal transmission unit 118.

  The operation data receiving unit 115 receives operation data by channel operation or the like from the battery-type communication device 23 accommodated in the television remote control 25 via the gateway device 21, and the battery accommodated in the ignition battery box of the gas range 26 Operation data regarding the ignition operation is received from the communication device 24 via the gateway device 21.

  The power consumption fluctuation calculation unit 123 uses the power consumption data received every 30 minutes, for example, from the smart meter 12 or the smart meter management server device 17 of the power company, to calculate the current power consumption relative to the previous power consumption. And calculating the absolute value of the difference (variation value) and comparing the variation value to a predetermined threshold value. For example, by using household appliances such as oven toaster, microwave oven, electric kettle, washing machine, vacuum cleaner, iron, electric stove, etc., the fluctuation value of power consumption exceeds the threshold, based on the lifestyle of the target household The threshold is preset.

  The timer control unit 121 receives the operation data related to the ignition operation of the gas range 26 when the operation data by the channel operation of the television remote control 25 is received from the battery type communication device 23 when the fluctuation value of the power consumption exceeds the threshold. The timer unit 119 is reset at each time when received from the battery type communication device 24, and measurement of elapsed time is zero-started. Therefore, the time measured by the timer unit 119 indicates that the channel remote control 25 is not operated, the ignition operation of the gas range 26 is not performed, and the variation of the power consumption is less than the threshold. It becomes.

  The safety required confirmation status judgment unit 125 is in a situation where the resident (safety watching target person) needs the safety confirmation when the measurement time of the timer unit 119 exceeds a predetermined time, typically 12 hours (safety safety confirmed status) Determine what it would be. When the safety signal confirmation unit 125 determines the safety confirmation status, the alarm signal transmission unit 118 typically carries the alarm signal, typically a portable phone such as a smartphone owned by a close relative of the safety target person's family, etc. The information processing terminal 29 is transmitted to the information processing terminal 31 of the security company for which the resident or his / her family has contracted. The family or security company of the subject who has received the alarm signal can contact the subject by telephone or the like, or rush to the home of the household to confirm the safety.

  FIG. 6 shows a safety watching process procedure by the safety watching server device 11 according to the present embodiment. Along with the activation of the process, the timer unit 119 is activated (step S1), reset by the timer control unit 121, and measurement of the elapsed time is started (step S2). In FIG. 7, the start time of the safety watching process is denoted as "t0".

  During the safety monitoring process, the power consumption data receiving unit 117 consumes power from the smart meter 12 or the smart meter management server device 17 of the electric power company at time t1, t2, t3, ... at predetermined time intervals such as 30 minutes. Receive volume data continuously. When the power consumption is received, the power consumption fluctuation calculation unit 123 calculates the absolute value (fluctuation value) of the difference between the power consumption and the power consumption received last time, and sets the fluctuation value as a predetermined threshold value. The comparison is performed, and the comparison result is output to the timer control unit 121. Further, the timer control unit 121 receives operation data regarding the channel operation and the like from the battery type communication device 23 stored in the television remote control 25 through the operation data receiving unit 115, and the battery stored in the ignition battery box of the gas range 26. It waits for reception of operation data relating to the ignition operation from the type communication device 24.

  The data of the elapsed time measured by the timer unit 119 is supplied to the required safety confirmation status determination unit 125. The safety confirmation status determining unit 125 compares the elapsed time with a preset time, for example, 12 hours (step S3). When the elapsed time has not reached 12 hours (No), the process proceeds to step S3. When the elapsed time reaches 12 hours (Yes), the process moves to step S7. In step S7, the alarm signal transmission unit 118 sends an alarm signal to the portable information processing terminal 29 such as a smartphone owned by the family of the watching target, such as a smartphone, and the information processing terminal 31 of the security company whose contractor or the family has contracted. Will be sent.

  The timer control unit 121 determines whether or not operation data (remote control operation data) related to channel operation and the like of the television remote control 25 is received from the battery type communication device 23 (step S4). If remote control operation data is received (Yes), the process returns to step S2, the timer unit 119 is reset to zero, and measurement of elapsed time is restarted. When the remote control operation data is not received (No), the process proceeds to the next step S5.

  In step S5, the timer control unit 121 determines whether or not operation data (ignition operation data) related to the ignition operation of the gas range 26 is received from the battery type communication device 24. When the ignition operation data is received, the process returns to step S2, the timer unit 119 is reset to zero, and measurement of the elapsed time is restarted. When the ignition operation data is not received (No), the process proceeds to the next step S6.

  In step S6, the timer control unit 121 uses the comparison result of the power consumption fluctuation value from the power consumption fluctuation calculation unit 123 and the threshold to determine whether the power consumption fluctuation value exceeds the threshold or not. judge. If the variation value of the power consumption amount exceeds the threshold (Yes), the process returns to step S2, the timer unit 119 is reset to zero, and measurement of the elapsed time is restarted. When the fluctuation value of the power consumption does not exceed the threshold (No), the process returns to step S3.

  As described above, the timer unit 119 is reset to zero as long as either remote control operation of the channel of the television remote control 25 or the like, ignition operation of the gas range 26, or exceeding of the threshold of fluctuation of power consumption occurs. The time measured by the timer unit 119 indicates the elapsed time from the latest time point among remote control operation, ignition operation, and exceeding the threshold of fluctuation of the power consumption amount. In other words, remote control operation is not performed either. Indicates a time during which the situation where the fluctuation of the power consumption is less than or equal to the threshold is continued.

  When this time reaches a preset time, for example, 12 hours, the alarm signal transmission unit 118 contracts a portable information processing terminal 29 such as a smartphone owned by the family of the watching target, the subject or the person A warning signal is sent to the information processing terminal 31 of the security company that has already been used, and safety confirmation can be made.

  According to the present embodiment, the presence or absence of the confirmation of the safety requirement is determined not only by the change in the power consumption of the target household but on the basis of the presence or absence of the manual operation of the television remote control or the like. The accuracy of can be significantly improved. Furthermore, the safety determination accuracy is further improved by increasing the number of battery-type communication devices 23, 24. As the battery-operated devices 25 and 26 to which the battery-type communication devices 23 and 24 are attached, those whose operation frequency is essentially different, for example, those whose operation frequency is relatively high in one day, and relatively regular operation are assumed By selecting one, it is possible to expect a marked improvement in safety determination accuracy. Of course, since the safety monitoring system can be introduced by attaching the battery-type communication devices 23 and 24 to the battery-driven devices 25 and 26, it is possible to greatly reduce the introduction burden.
