Description

DETAILED DESCRIPTION OF THE INVENTION Field of Industrial Application The present invention relates to a gas shut-off device that uses a microcomputer to externally write the internal mode of a gas shut-off device that has recently become popular in the pipes of major city gas supply companies. This invention relates to a mode writing device.

2. Description of the Related Art An example of a conventional gas cutoff device will be described below with reference to the drawings.

FIG. 4 shows a configuration diagram of a conventional gas cutoff device. In Fig. 4, 1 is a gas cutoff device, 2 is a gas meter,
3 is a flow rate sensor attached to the gas meter 2, 4 is a shutoff valve that shuts off the gas passage, 6 is a control unit, 6 is a group of switches that switches the mode of the control unit 6, and 7 is an LED display that displays the reason for shutoff and an alarm. Sections 8 and 8 are reed switch input sections that are turned on by a magnet from the outside to cut off the gas passage. The function of the gas cutoff device 1 is to transmit the flow rate flowing through the gas meter 2 as shown by the arrow to the control unit 6 using the flow rate sensor 3.
The presence or absence of an abnormal flow rate pattern is checked, and if an abnormality is found, the shutoff valve 4 is operated to shut off the gas passage, and the LED of the display section 7 is turned on to notify the outside of the reason for the shutoff. It is. The switch group 6 is the gas cutoff device 1
The control unit 5 includes an input switch for changing the set value (judgment value) depending on the type of gas flowing through the gas meter 2 and the meter number, and an input that allows the set value to be changed to a certain extent according to the consumption pattern of each household. It's a switch. The former input switch is a switch that is set in advance before installing the printed circuit board into the meter. The latter input switch is a switch that is changed after the meter is installed in each home. FIG. 6 is a diagram showing a printed circuit board having the above structure installed on the upper part of the gas meter. 17 is the back butt, 18 is L
The LED window 21 is a printed circuit board that allows the ED light to pass through to the outside. The LEDs on the display can be checked from the outside via the LED window.

Problems to be Solved by the Invention However, according to the above configuration, when changing the gas after setting the gas type and meter number once and installing it in the meter, it is necessary to remove the back cover and remove the printed circuit board. You have to take it out and change the settings. The same applies to changes in setting values according to consumption patterns. Gas meters are often installed in narrow spaces, making it difficult to change set values, and causing problems such as the possibility of incorrect settings.

Means for Solving the Problems In order to solve the above problems, the present invention provides a receiving section that receives a signal from the outside, a determining section that determines whether the information inputted from the receiving section is incorrect, and a result of the determination. A gas cutoff device includes a transmitting section for transmitting data to the outside, a storage means for storing input information according to a determination result, and a control section for controlling gas cutoff, and a receiving section of the gas cutoff device is provided with a predetermined internal mode. a transmitting unit for inputting information to write the information, a receiving unit for receiving the output of the transmitting unit of the gas cutoff device, a control unit for controlling the transmission and reception, an input unit for the control unit, and a display unit for displaying the reception results. This is a gas cut-off mode writing device.

Operation: By the above means, write information of a predetermined internal mode is inputted to the input section of the gas cutoff device by the transmitting section, the information is checked by the determining means, and if there is no error, it is stored in the storage means and the contents are stored in the gas cutoff device. The transmitter of the cutoff device allows
The internal mode can be rewritten from outside the gas meter by transmitting the information to the receiving section and displaying on the display section that the writing was successful.

EXAMPLE An example of the present invention will be described below with reference to FIGS. 1, 2, and 3.

In FIG. 1, the same reference numerals as in FIG. 4 represent the same parts as in the conventional example, and detailed explanation thereof will be omitted, and the explanation will focus on the different parts. Reference numeral 8' indicates a receiving section which also functions as a conventional reed switch input section, 10 indicates a determining means for checking whether there is an error in the received information pattern, 9 indicates a storage means for storing information according to the information pattern, and 7' indicates a receiving section. This transmitter also serves as a conventional LED display unit for transmitting the results of the determination means 10.

16 is an external device, and 11' is the receiving section 8 of the gas cutoff device 1.
A transmitter that transmits information to the reed switch input section by turning on and off the electromagnetic coil.

Reference numeral 13' denotes a receiving section that receives lighting/blinking of the transmitting section 7' (LED) of the gas cutoff device 1 using a phototransistor. 12
is a control section that controls the transmitting section 11' and the receiving section 13'. 14 is an input section for setting which internal mode is to be rewritten, and 16 is a display section for notifying whether or not the rewriting has been performed normally. Figure 2 shows a reed switch 8 for transmitting and receiving information. LIED7. The positional relationship between the phototransistor 13 and the electromagnetic coil 11 is shown. 19 is a unit containing the phototransistor 13 and the coil 11;
20 is a cable line. FIG. 3 shows an example of a format for transmission and reception between the gas cutoff device 1 and the external device 16.

In Figures 1 and 2, when performing gas conversion or changing set values according to consumption patterns, place the unit on the front of the upper case of the gas meter 2, and set which internal mode to rewrite using the input section 14 of the external device 16. Then, the information is given to the reed switch 8 via the electromagnetic coil 11, and the determining means 10 determines the error check code in the format shown in FIG. 3 within one hour to determine whether there is any error in the information. , the results are stored in the storage means 9 according to the information, and the results are transmitted to the phototransistor 13 by turning on the LED 7 for two predetermined times, and displayed on the display section 15 of the external device 16.
The results will be displayed and notified.

In this way, the internal mode can be converted and it can be known whether the rewriting has been performed normally.

In addition, by using the unit 19 and the format used, setting values can be changed remotely, and connection with home automation etc. is easy and expandable. Also, unit 1
As 9, LED 7 of the gas cutoff device, reed switch 8
You can save energy by using both.

Effect of the invention According to the present invention described above, the following effects can be expected.

(1) Easily convert the internal mode of set values during gas conversion and consumption patterns by applying an external device to the gas cutoff device while it is actually installed, without opening the back cover of the gas cutoff device. can be done.

(2) When rewriting, the gas cutoff device determines whether the information is incorrect and stores it only if it is correct, and notifies the result. There are no setting errors and reliability is improved.
