に確認して設定条件の入力が完了する。As described above, the main body 1 is driven by the built-in battery 2 in order to prevent a power failure or the like that occurs when the main body 1 is driven by a commercial power supply and to improve operational reliability. is there. The operation of the fluid fuel cutoff control device is as follows. First, the setting condition is input to the control unit 3 of the main body 1 by the setting device 20. In this case, the setting device 20
Can be operated close to the main body 1, the reed switch 11 of the main body 1 can be operated by the operation magnet 24, and the main body 1 can be operated by the light receiving element 22.
The optical signal input from the light-emitting element 6 is set in a state where it can be received. Then, the controller 21 outputs a setting condition composed of, for example, a binary signal, and the transistor 25 is turned on / off in accordance with the setting condition, and the operation magnet 24 is excited or de-energized. The reed switch 11 of the main body 1 is turned on / off by excitation or non-excitation of the operation magnet 24, and the setting condition is input to the signal input terminal P1 of the control unit 3. In this case, following the setting conditions like the transmission protocol shown in the timing chart of FIG.
An error detection code is output to detect an error (for example, a signal that contradicts a set condition is continuously output, and an error is detected by comparing the set condition with the contradictory signal). The control section 3 of the main body 1 outputs the input setting conditions from the signal output terminal P0. The transistor 9 is turned on / off in response to the output, and an optical signal corresponding to the on / off of the transistor 9 is emitted from the light emitting element 6. This optical signal is received by the light receiving element 22 of the setting unit 20, amplified by the amplifier 23, and input to the signal input terminal Q1 of the control unit 21. Also in this case, as shown in FIG. 3, an error detection code is output following this set condition to detect an error. Then, the control unit 21 of the setting device 20 sets the setting conditions input to the main body 1 and the main body 1 first.
Is compared with the setting conditions output in step (1), and further confirmation that there is no error is completed.

When the flow rate detection signal from the flow rate sensor 4 is, for example, equal to or less than the set flow rate under the set conditions, the control unit 3 does not output the control signal and the cutoff valve 5 is in the “open” state. Here, for example, when it is determined that a continuous gas outflow occurs and the flow rate detection signal from the flow rate sensor 4 exceeds the set flow rate and there is a large amount of gas leakage leading to an explosion accident, the control unit 3 controls the signal output terminal P3. Outputs a control signal to the transistor 12 to turn on the transistor 12. When the transistor 12 is turned on, the operation coil 5A of the shut-off valve 5 is energized, and the shut-off valve 5 is switched from "open" to "closed" to shut off the gas supply path. At the same time, for example, a pulse signal is output from the signal output terminal P0, the transistor 9 is turned on and off, the light emitting element 6 is turned on and off, and an operation signal indicating that the gas supply path is cut off is displayed. When there are a plurality of setting conditions, a plurality of operation signals are displayed by changing the pulse width or the pulse period of the pulse signal in accordance with each setting condition.

No problem. However, this signal input means is mainly used, for example, when inputting setting conditions at the start of use of the device, and its use frequency is low, and a reed switch which is mechanically "open" and has no leakage current is built in. This is effective in reducing battery consumption.

度が高いので特に問題となる。In the above-described control device, the light-emitting element is used for both transmitting the set condition input when the set condition is input and displaying an operation signal when the control device is operated. ing. Normally, the luminous intensity of this light-emitting element may be a fraction of the luminous intensity at the time of displaying the operation signal (the luminous intensity required for visual observation) as compared to the luminous intensity at the time of transmitting the set conditions. That is, the current of the light emitting element at the time of transmitting the setting conditions requires, for example, 10 mA, but the current of the light emitting element at the time of displaying the operation signal is sufficient to be 3 mA. However, this light-emitting element has only one energizing current path, so the energizing current is set to the current value at the time of transmission of the setting condition having a large current value. The built-in battery drains faster. This is a particular problem because the display of the operation signal is frequently used for transmitting the setting conditions.
