Description

  The present invention relates to a gas shut-off device that outputs various data information at the end of the device life to the outside in a shut-off device that monitors the usage state of a gas appliance that uses city gas, LP gas, or the like.

  This type of conventional shut-off device is configured as shown in FIG. 2 for a gas shut-off device, for example (see, for example, Patent Document 1). FIG. 2 shows a control block diagram of a conventional gas shut-off device.

Reference numeral 3 denotes a shut-off valve, which stops or supplies gas in the flow path. Reference numeral 4 denotes a voltage drop detection unit, which detects a battery voltage taking into account a predetermined time that goes back from the operation guarantee voltage in which the capacity of the battery power supply unit 2 capable of operating the gas shut-off device 1 remains. Signal A is output.

  5 is an opening acceptance unit that accepts opening of the shut-off valve from the time when the voltage drop signal A is input, and opens when there is an opening request (opening request switch or input of an opening signal by communication). A stopper request signal C is output. A timer unit 6 counts a predetermined operation guarantee time from when the voltage drop signal A is input, and outputs a plug opening completion signal D. Reference numeral 7 denotes an opening function stop unit which outputs a closing stop signal E for stopping the opening according to the opening request signal C when the opening end signal D is input. Reference numeral 8 denotes a gas shut-off control unit, which shuts off the shut-off valve 3 when the battery voltage drop signal A or the closure stop signal E is inputted, and when the opening request signal C is inputted before the input signal of the closure stop signal E. The shut-off valve 3 is opened.

  Next, the operation of the configuration of the conventional example will be described. When the voltage drop detection unit 4 checking the consumption level of the battery power supply unit 2 detects the battery consumption voltage, the battery voltage drop signal A is output to the unplugging reception unit 5, the timer unit 6 and the gas cutoff control unit 8. . The gas cutoff control unit 8 to which the voltage drop signal A has been input outputs the first cutoff command signal B1 to operate the cutoff valve 3 and close the gas passage.

When the timer section 6 finishes counting, the plug opening end signal D is output, so the plug opening function stop section 7 outputs the plug opening stop signal E and stops accepting the plug opening request. The gas cutoff device 1 to which the closing stop signal E is inputted outputs the second cutoff command signal B2 to close the cutoff valve 3.

In the gas shut-off device 1 attached to the flow path through which medium gas such as city gas and LP gas flows, the voltage drop detection unit 4 measures the voltage of the battery power supply unit 2 at a predetermined time interval and monitors the degree of battery consumption. ing. A lower limit voltage at which the gas shut-off device 1 can be operated is set in advance as an operation guarantee voltage, and a voltage value when the voltage is reversed for a required number of days from here is set as a battery consumption voltage. The voltage drop detection unit 4 monitors the battery voltage and detects the battery voltage when the battery is consumed. That is, after the battery consumption voltage is detected for the required number of days, the shutoff valve 3 can be opened only during the period when the voltage of the battery power supply unit 2 drops to the operation guarantee voltage, and a grace period is provided until the gas shutoff device 1 is replaced. It is a thing.

  In FIG. 1, there are 9 power supply voltage units. Reference numeral 10 denotes an external output unit. Reference numeral 11 denotes a voltage drop detection unit that monitors the battery voltage of the battery power supply unit 9 at regular time intervals. Reference numeral 12 denotes a display unit that displays a battery voltage drop or the like in the power supply voltage unit 9 if there is any. A shut-off valve 13 shuts off the gas passage when an abnormality occurs. Although not shown in the figure, the battery power supply unit 9 and the external output unit 10 are connected to a microcomputer, which is a processing device that performs flow rate measurement and various security determinations. Similarly, although not shown in the figure, this apparatus and an external apparatus with a separate power source are configured to receive and store various data information.

  The operation and action of the gas shut-off device configured as described above will be described below.

  First, the voltage drop detection part 11 monitors the voltage of the power supply voltage part 9 for every predetermined time. Then, the battery voltage drop is determined because the battery consumption voltage is lower than the battery consumption voltage set in consideration of battery consumption for a predetermined time that goes back from the operation guarantee voltage that is the lower limit value at which the shut-off valve 13 can be operated. By outputting an operation signal to the shut-off valve 13, the life of the apparatus is completed. The voltage drop detection unit 11 outputs a signal so that various data information at that time is output to the outside via the external output unit 10 when the shut-off valve operation signal is output after the battery voltage drop determination. Upon receiving the signal from the voltage drop detection unit 11, the external output unit 10 connected to the microcomputer outputs various data stored in the microcomputer at that time to the outside. Here, since the battery consumption for the external output unit 10 to output various data to the outside is extremely small, it is ignored.

Further consideration can be made when designing the next product based on this data, and it is possible to improve the gas shutoff device with higher safety and cost.

  In addition, the voltage drop detection unit 11 determines a battery voltage drop and outputs a signal to output various data information at the time of battery voltage drop determination to the outside via the external output unit 10, and to the shut-off valve 13 after a predetermined time. An operation signal may be output.

  As a result, some abnormality occurs in the battery power supply unit 9 and battery consumption rapidly proceeds. By a predetermined time after the voltage drop detection unit 11 determines the battery voltage drop, the voltage drop of the battery power supply unit 9 advances and the microcomputer Even if the various data stored in the above are destroyed, the external device receives and stores various data information at the time of battery voltage drop determination, and the external device receives the various data information at the time of battery voltage drop determination. By analyzing this data, it is possible to analyze the cause of the rapid battery consumption of the apparatus. Based on this data, further considerations can be made when designing the next product, and it is possible to improve the gas shutoff device with higher safety.

  The voltage drop detection unit 11 determines a battery voltage drop and outputs a signal to output various data information at the time of battery voltage drop determination to the outside via the external output unit 10. The operation signal may be output to 13 and the signal may be output so that various data information at that time is output to the outside.

  As a result, some abnormality occurs in the battery power supply unit 9 and battery consumption rapidly progresses. By a predetermined time after the voltage drop detection unit 11 determines the battery voltage drop, the voltage drop of the battery power supply unit proceeds and the microcomputer enters the microcomputer. When the stored various data is destroyed, the external device receives and stores various data information at the time of battery voltage drop determination by the external device. By analyzing this data, it is possible to analyze the cause of the rapid battery consumption of the apparatus. In addition, when the voltage drop detection unit 11 outputs an operation signal to the shut-off valve 13 after the battery voltage drop determination that is the end of the life of the apparatus, various data information at that time is again output to the outside via the external output unit. Give a signal. Upon receiving the signal from the voltage drop detection unit 11, the external output unit 10 connected to the microcomputer outputs various data stored in the microcomputer at that time to the outside. After that, even if the battery power consumption 9 causes a voltage drop and the various data stored in the microcomputer are destroyed, the external device not described here receives and stores the various data information. When performing the analysis, data at the end of the life of the device can be obtained. In this way, various data can be analyzed regardless of whether the battery power supply is abnormal or normal. Further consideration can be made when designing the next product based on this data, and it is possible to improve the gas shutoff device with higher safety and economy.

  As described above, the gas shutoff device according to the present invention receives and stores various data information by the external device even when the battery power consumption causes the voltage drop of the battery power supply unit to proceed and the various data stored in the microcomputer is destroyed. Therefore, since various data at the end of the life of the device remains stored, it is possible to perform data analysis, so that it can be applied not only to gas but also to battery voltage determination devices such as water supply, power, and combustion fuel. .
