  FIG. 3 is a diagram illustrating an example of setting items that can be block-displayed by the block selection display function 13 c of the display unit 13. The display unit 13 can specify a function group for each block, with one function group as one block. That is, in the figure, it is shown that the setting corresponding to the mark 18 can be changed, and the function whose setting is changed can be selected depending on whether or not this mark is displayed. In this example, the setting is divided into a block 1 setting and a block 2 setting. The block 1 setting includes, for example, “pressure type micro leak warning function stop”, “pressure abnormal warning function stop”, “flame registration”, and the like. The function group is included, and the block 2 setting includes, for example, “20 minutes fixed for categories 5 and 6”, “stop of unconnected detection function”, “extended 1”, “extended 2”, “fixed category 2”, “ A function group including “continuous use time cutoff value fixed table setting” and the like is included.

  Here, an outline of the function group included in the block 1 setting and the block 2 setting will be described. In general, gas meters are standardized by the Japan Gas Meter Industry Association. Microcomputer type flow detection type automatic gas shut-off device (II type) for liquefied petroleum gas, microcomputer type flow rate detection type automatic gas shut-off device for liquefied petroleum gas ( L type), microcomputer type flow detection type automatic gas shut-off device (C type) for liquefied petroleum gas, microcomputer type flow rate detection type automatic gas cutoff device (B type) for liquefied petroleum gas, microcomputer type flow rate detection type automatic for liquefied petroleum gas The gas meter 1 according to the present invention is classified as a safety gas meter such as a gas shut-off device (S type) and a microcomputer type flow rate detection type automatic gas shut-off device (SB type) for liquefied petroleum gas. To do.

  First, in Block 1 setting, “Pressure type micro leak warning stop” means that the pressure in the supply pipe is measured every certain time (15 minutes, etc.) when the gas is not used, and the pressure immediately after the gas use is stopped. When the pressure difference measured every time is not continuously observed for a predetermined number of days (for example, 30 days), the function of stopping the leakage warning is stopped. The “Pressure Abnormal Warning Function Stop” measures the pressure of the gas meter 1 during use of the gas, and warns when the value frequently deviates from an appropriate value (for example, 2.3 kPa to 3.3 kPa). This is a function to stop the function to be issued. In addition, “flame registration” is a function that registers the fire at the consumer's house that continuously uses the fire of the gas consuming equipment in the microcomputer and displays the leak warning only in the case of a slight leak, distinguishing it from the flow-type micro leak warning. is there.

In Block 2 setting, “Fixed for 20 minutes in sections 5 and 6” means that carbon monoxide generated by incomplete combustion of type 4 and type 5 open instantaneous water heaters that do not have an incomplete combustion prevention function. In order to prevent gas accidents due to (CO), this is a function for fixing the time limit (20 minutes here) of the usage time monitoring sections 5 and 6. In addition, the said division is a flow rate monitoring division, and is defined for every standard of the gas meter. “Non-connection detection function stop” is a function for stopping the non-connection detection function when there is no gas appliance indoors and the gas meter 1 is installed in a gas supply facility or the like outside the installation target of the gas leak alarm. “Expansion 1” is a facility that uses a solar hot water supply system, and the automatic setting function cannot be followed in response to changes in the use of appliances. This is a function to increase the lower limit of the value. “Expansion 2” is a function that cancels the continuous use time blocking function in order to deal with special usage forms of business facilities of 2.5 m ³ / h or less such as resort facilities, and is unlimited in all categories.

  “Category 2 fixed” means that the S type microcomputer meter category 2 is longer than the time limit of the type II microcomputer meter category 2 and is fixed to the II type setting value of 160 minutes or less. As a measure to prevent the pot from being burnt, it has been added so that it can also select a hot fire cutoff function. “Continuous usage time cutoff value fixed table setting” means that when the gas meter 1 determines that the usage state of the gas appliance is not normal, forgetting to turn off the gas appliance or incomplete closing of the appliance plug, etc. This is a function of determining a gas leak by driving the shutoff valve to shut off the gas passage, displaying the reason for shutoff, and setting a fixed shutoff value for outputting a signal to the communication terminal in the table.

  4 is a diagram showing the relationship between the function group included in the block 1 setting shown in FIG. 3 and its setting pattern, and FIG. 5 is the function group included in the block 2 setting shown in FIG. 3 and its setting pattern. It is a figure which shows the relationship.

  In FIG. 4A, the function group included in the block 1 setting, that is, the function group consisting of “pressure-type microleakage warning function stop”, “pressure abnormality warning function stop”, and “flame registration” has a setting pattern 0. 8 patterns of setting pattern 7 are set. In each setting pattern, “◯” means that function setting is present and “−” means that function setting is not present. FIG. 4B shows a display form by the block selection display function 13c of the display unit 13, and a mark 18 is given corresponding to the setting pattern 0 to the setting pattern 7 shown in FIG. The position of the mark 18 matches the arrangement order of the setting items of the block 1 setting shown in FIG. 3. For example, “flame registration” and “pressure abnormality warning function stop” are set in the setting pattern 6. Therefore, the mark 18 is given to two corresponding places.

  Similarly, in FIG. 5A, the function groups included in the block 2 setting, that is, “Fixed for 20 minutes in sections 5 and 6”, “Non-connection detection function stop”, “Extended 1”, “Extended 2”, Twelve patterns of setting pattern 0 to setting pattern 11 are set in the function group composed of “category 2 fixed” and “continuous use time cutoff value fixed table setting”. With function setting, “-” means no function setting. FIG. 5B shows a display form by the block selection display function 13c of the display unit 13, and a mark 18 is given corresponding to the setting pattern 0 to the setting pattern 11 shown in FIG. The position of the mark 18 matches the arrangement order of the setting items of the block 2 setting shown in FIG. 3. For example, “extension 1” and “unconnected detection function stop” are set in the setting pattern 7. Therefore, the mark 18 is given to two corresponding places.

  FIG. 6 is a diagram for explaining a flow of setting change processing of various functions using an existing operation switch provided in the gas meter 1. The setting change means 16 provided in the gas meter 1 is an operation switch (test cutoff switch 10d, container reset) provided in the gas meter 1 in a test cutoff state by the test cutoff switch 10d or a cutoff valve opened by the cutoff valve opening switch 14b. In accordance with a predetermined operation (for example, the number of times the switch is pressed or the pressing time) for the switch 10e and the shut-off valve opening switch 14b), a plurality of types of setting patterns for changing the setting of the function are switched and displayed on the display unit 13. The setting data of the setting value storage means 17 is changed based on the setting pattern selected from the inside. The specific processing flow will be described below. In the following description, plural types of setting patterns are displayed divided into two blocks. However, the present invention is not limited to this, and a display form that is not divided into blocks may be used, or a display form that is divided into three or more blocks. It is good.

  In FIG. 6, first, in the test cutoff state of the gas meter 1, when the test cutoff switch 10d is continuously pressed to confirm the input (S1) and the test cutoff occurs, the display unit 13 displays “Block 1 setting mode”. ”Is displayed. In this case, a portion corresponding to the block 1 setting shown in FIG. 3 is displayed surrounded by a frame. When the input is confirmed by pressing the container reset switch 10e continuously for 2 seconds or more during the “block 1 setting mode” (S2), the setting pattern 0 to the setting pattern 7 (total) shown in FIG. 8 patterns) are sequentially switched and displayed every second, for example.

  Further, when the input of the test cutoff switch 10d is confirmed during the “block 1 setting mode” (S3, S4), the display shifts to the “block 2 setting mode”. In this case, a portion corresponding to the block 2 setting shown in FIG. 3 is displayed surrounded by a frame. At the same time, the set value of the “block 1 setting mode” is stored. If the input is confirmed by pressing the container reset switch 10e continuously for 2 seconds or more during the “block 2 setting mode” (S5), the setting pattern 0 to the setting pattern 11 (total) shown in FIG. 12 patterns) are sequentially switched and displayed every second, for example. At this time, if the input of the test cutoff switch 10d is confirmed during the “block 2 setting mode” (S6, S7), the display shifts to the “block 1 setting mode”. At the same time, the setting value of the “block 2 setting mode” is stored. However, when setting patterns 1, 3 and 6 for setting the block 2, that is, a pattern including the “fixed category 2” function, the display shifts to “select category 2 time” (S8). The steps after (S8) are referred to as “block 2 hour setting mode”.

  When the input is confirmed by continuously pressing the container reset switch 10e during this “block 2 hour setting mode (section 2 time selection)” (S9), time data that can be set in the “section 2 fixed” function (for example, 160 minutes, 30 minutes, etc.) are sequentially switched and displayed at predetermined positions on the display unit 13 by the sub-counter display function 13d. When the input of the test cutoff switch 10d is confirmed during the “block 2 hour setting mode (section 2 hour selection)”, the display shifts to “block 1 setting mode”. At the same time, the set value of “block 2 hour setting mode (section 2 hour selection)” is stored.

  Here, in the display states of the “block 1 setting mode”, the “block 2 setting mode”, and the “block 2 time setting mode (section 2 time selection)”, a shipping mode is required unless operated for a predetermined time (for example, 30 seconds). Transition to transition state. At the same time, the setting values in each mode are saved. The shipping mode is a mode in which various functions at the time of shipment of the meter such as an automatic setting function are selected and set to minimize the battery consumption of the gas meter 1. In addition, when the shut-off valve open switch 14b is confirmed to be input in each of the display states of the “block 1 setting mode”, “block 2 setting mode”, and “block 2 time setting mode (section 2 time selection)”, the return safety confirmation is performed. Transition to the state. At the same time, the setting values in each mode are saved. In this return safety confirmation state, when the shutoff valve is returned after shutting off the gas passage, it is checked whether there is a gas leak on the downstream side of the shutoff valve, and if there is a gas leak, it is shut off and shut off again. A state where the reason is displayed and a signal can be output to the communication terminal. When these settings are saved, if they cannot be saved due to setting conditions, etc., the contents before the setting remain unchanged.

  FIG. 7 is a flowchart for explaining an example of setting change processing of various functions of the gas meter 1 to which the present invention is applied. In addition, this example shall be demonstrated referring the screen transition of the display part 13 of the gas meter 1 shown in FIG. First, the gas meter 1 determines whether or not the test cutoff switch 10d has been pressed twice in succession (step S11), and when it detects that the test cutoff switch 10d has been pressed twice (YES), “block 1 The display shifts to “setting mode” (step S12). In step S11, when it is not detected that the test cutoff switch 10d is continuously pressed twice (in the case of NO), an input standby state is entered.

  Next, in the “block 1 setting mode”, the gas meter 1 determines whether any one of the operation switches (the test shut-off switch 10d, the container reset switch 10e, and the shut-off valve opening switch 14b) is pressed (step S13). When the pressing of the switch is detected (in the case of YES), it is determined whether the pressed operation switch is the test cutoff switch 10d, the container reset switch 10e, or the cutoff valve opening switch 14b (step S14). In step S13, if pressing of the operation switch is not detected (in the case of NO), the process returns to step S12 and enters an input standby state in the “block 1 setting mode”.

  Next, in step S14, when it is determined that the pressed operation switch is the container reset switch 10e (in the case of the container in the figure), the process proceeds to block 1 selection, and the setting pattern 0 corresponding to the block 1 setting is set. To setting pattern 7 (eight patterns in total) are sequentially switched and displayed, for example, every second (step S15). When it is determined that the pressed operation switch is the shut-off valve opening switch 14b (in the figure, in the case of valve opening), the process proceeds to step S25 to select and confirm the setting pattern selected at that time. (Step S25). When it is determined that the pressed operation switch is the test cutoff switch 10d (in the case of a test in the figure), the display shifts to “block 2 setting mode” (step S16).

  Next, in the “block 2 setting mode”, the gas meter 1 determines whether any of the operation switches (the test shutoff switch 10d, the container reset switch 10e, and the shutoff valve opening switch 14b) has been pressed (step S17). When pressing of the switch is detected (in the case of YES), it is determined whether the pressed operation switch is the test shutoff switch 10d, the container reset switch 10e, or the shutoff valve opening switch 14b (step S18). In step S17, when pressing of the operation switch is not detected (in the case of NO), the process returns to step S16 and enters an input standby state in the “block 2 setting mode”.

  Next, when it is determined in step S18 that the pressed operation switch is the container reset switch 10e (in the case of a container in the figure), the process proceeds to block 2 selection, and the setting pattern 0 corresponding to the block 2 setting is set. To setting pattern 11 (12 patterns in total) are sequentially switched and displayed, for example, every second (step S19). When it is determined that the pressed operation switch is the shut-off valve opening switch 14b (in the figure, in the case of valve opening), the process proceeds to step S25 to select and confirm the setting pattern selected at that time. (Step S25). Further, when it is determined that the pressed operation switch is the test cutoff switch 10d (in the case of a test in the figure), whether or not there is a time setting in the function included in the selected setting pattern (for example, the category 2 fixed function) In such a case, it is determined that there is a time setting (step S20).

  In step S20, if there is no time setting (in the case of NO), the process proceeds to the display of “block 1 setting mode” in step S12. In step S20, if there is a time setting (in the case of YES), the process proceeds to the display of “block 2 time setting mode” (step S21).

  Next, in the “block 2 hour setting mode”, the gas meter 1 determines whether any one of the operation switches (the test shutoff switch 10d, the container reset switch 10e, and the shutoff valve opening switch 14b) has been pressed (step S22). When the pressing of the operation switch is detected (in the case of YES), it is determined whether the pressed operation switch is the test cutoff switch 10d, the container reset switch 10e, or the cutoff valve opening switch 14b (step S23). If it is not detected in step S22 that the operation switch has been pressed (NO), the process returns to step S21 to enter an input standby state in the “block 2 hour setting mode”.

  Next, when it is determined in step S23 that the pressed operation switch is the container reset switch 10e (in the case of a container in the figure), the process proceeds to block 2 time selection and the time that can be set for the corresponding function. Data (for example, 160 minutes, 30 minutes, etc.) is sequentially switched and displayed at a predetermined position on the display unit 13 by the sub-counter display function 13d (step S24). When it is determined that the pressed operation switch is the shut-off valve opening switch 14b (in the figure, in the case of valve opening), the process proceeds to step S25 to select and confirm the setting pattern selected at that time. (Step S25). If it is determined that the pressed operation switch is the test cutoff switch 10d (in the figure, in the case of a test), the process returns to step S12 to enter an input standby state in the “block 1 setting mode”.

  In the display states of the “block 1 setting mode”, the “block 2 setting mode”, and the “block 2 time setting mode”, if no operation is performed for a predetermined time (for example, 30 seconds), the mode shifts to the shipping mode transition state. At the same time, the setting values in each mode are saved. Further, when the input of the shut-off valve open switch 14b is confirmed in the display states of the “block 1 setting mode”, “block 2 setting mode”, and “block 2 time setting mode”, the state shifts to the return safety confirmation state. At the same time, the setting values in each mode are saved.

  According to the present invention, a plurality of types of setting patterns for changing the setting of the function can be automatically switched and displayed in accordance with a predetermined operation (for example, the number of times the operation switch is pressed or the pressing time). Thus, the operator's operability can be improved, and by displaying a settable numerical value such as time data on the sub-counter, the operator's selection load can be reduced. Furthermore, since the setting pattern can be displayed divided into blocks, the operator can easily perform the selection operation.
