[Prior Art]

 A propane gas cylinder installed in a user's home such as an ordinary household by a gas supply company is attached and managed by the gas supply company by assigning a number to each cylinder. As a management method, a cylinder delivery worker reads the cylinder number on the spot and writes it on a designated form, and after returning to the gas supply company, inputs predetermined data such as a host computer. In addition, if there are any deficiencies in the safety inspection items for the supply equipment such as measures to prevent the cylinder from falling over, the worker will check it on site and write it on a specified form, and after returning to the office, enter it on the host computer. However, since such a method is mainly manual work, there are problems in accuracy of input data and efficiency of paperwork.

On the other hand, as shown in FIG. 14, a handy memory 51 receives an input of a cylinder number and a safety inspection item and stores the input data in a RAM, and an input of data read by the handy memory 51. There is a gas equipment management data processing device including a transmission repeater 53 and a host computer 57 that receives data input from the transmission repeater 53 via a transmission cable 55.

The handy memory 51 is a pocket-sized data input device, and data is input by using the keyboard 51a or reading a bar code by the hand scanner 51b. Such data input operation is performed for each cylinder on site, and after returning to the gas supply company, the handy memory 51 is connected to the transmission repeater 53 and the memory data stored in the handy memory 51 is stored in the host computer. 57 through optical communication. The host computer 57 performs processing such as outputting the sent data as a hard copy 59 by a printer (not shown). The handy memory 51 is operated by a rechargeable battery, and is connected to a charger 61 to be charged as shown in FIG.

[0005]

[Problems to be solved by the device]

 However, although such a conventional gas appliance management data processing device improves the accuracy of input data and the efficiency of clerical processing compared to a manual operation-based device, it has the following problems.

(1) A worker has to carry the handy memory 51, which is a small size but hinders the delivery work of the cylinder.

(2) When the data processing at the gas supply company after returning to the office is concentrated, the processing work cannot be performed smoothly and becomes troublesome, and when a dedicated data processing member is assigned, It costs a minute.

(3) If the battery of the handy memory 51 runs out in the middle of the process, it becomes impossible to perform the input work, and there is also a risk that the data input at other sites up to that point will be lost.

(4) The work of charging the handy memory 51 is a trifle, but it is troublesome. Therefore, the present invention does not require a dedicated input device for inputting management data, and aims to enable smooth data processing at a gas supply company.

【Example】

 An embodiment of the present invention will be described below with reference to the drawings.

FIG. 2 is a circuit configuration block diagram of a gas equipment management data processing device A showing a first embodiment of the present invention, and FIG. 3 is a front view of a microcomputer gas meter 1 equipped with this gas equipment management data processing device A. It is a figure. As shown in FIG. 4 and FIG. 5, the microcomputer gas meter 1 is provided in the body 3 to measure the gas flow rate, and in the front of the upper case 5 mounted on the upper part of the body 3, the microcomputer gas meter 1 is provided. In addition to being equipped with a totalization indicator 7 that cumulatively displays the gas flow rate measured in step 1, the abnormal gas flow rate is detected, and an alarm is issued and control such as closing the built-in shutoff valve is performed. It has a built-in control circuit consisting of a microcomputer with a monitoring function. On the front surface of the body 3, there is arranged a terminal box 9 provided with terminals for connecting with a communication line for transmitting gas flow rate information to a gas supply company having an information management facility. The gas equipment management data processing device A shown in FIG. 2 is mounted on the inner surface. However, a telephone line network controller (NCU) 27, which will be described later and is included in the gas equipment management data processing unit A, is not mounted on the inner surface of the lid 11 of the terminal box 9, but is installed inside the house.

In addition to the NCU 27, the gas equipment management data processing device A includes an operation switch 13 as an input means for inputting management data of the gas equipment, and a liquid crystal display 15 as a display means capable of displaying the inputted data. It is composed of a communication interface circuit 17 capable of transmitting the input data to the NCU 27 and a micro computer for displaying the data input from the operation switch 13 on the liquid crystal display 15 and sending the data to the communication interface circuit 17. And a control circuit 19 as control means. Reference numeral 21 is a battery serving as a drive power source for the gas equipment management data processing apparatus A.

The input data from the operation switch 13 is the number assigned to each cylinder for the installation and recovery management of the propane gas cylinder installed in the user's house, or the supply equipment such as the cylinder fall prevention measure. There are code numbers corresponding to various safety inspection items. Of the above input data, the cylinder number shall be displayed in 4 digits using alphabets and arithmetic figures, and the code number of the safety inspection item shall be 2 digits of arithmetic figures only. The cylinder number consists of 26 letters of alphabet and 10 letters of arithmetic number, and even if it has 4 digits, 36 ⁴ = 1679616 can be expressed, which is sufficient. On the other hand, for safety inspection items, the delivery staff carries the inspection item table containing the inspection items 1 to 13 as shown in Fig. 6 and inputs the code number of the item in which the equipment is deficient.

The operation switch 13 includes an item selection key SW ₁ for selecting an input item, data keys SW ₂ and SW ₃ for inputting data such as a cylinder number, and a data determination key SW ₄ for determining input data. It consists of four keys. When the item selection key SW ₁ and the data key SW ₃ are pressed at the same time, the control circuit 19 activates the gas equipment management data processing device A, and the liquid crystal display 15 displays 0 when the data key SW ₂ is pressed. → 1 → 2 → ... → 9 → A → ... → Z are displayed in sequence, and every time the data key SW ₃ is pressed, the liquid crystal display 15 reversely displays Z → Y → ... → A → 9 → 8 → ... → 0 is displayed sequentially. Further, when the data determination key SW ₄ is pressed at the time when the desired data is displayed on the liquid crystal display 15 for each digit by the above operation, the control circuit 19 determines the alphabet or the numeral for that digit, When the data determination key SW ₄ is pressed for 1 second or longer after all digits have been determined, the data is stored in the memory in the control circuit 19.

As shown in the schematic configuration diagram of the entire system including the gas device management data processing device A of FIG. 7, the microcomputer gas meter 1 has a communication signal line 23 dedicated to the gas device management data processing device and a conventional communication signal line 23. Is connected to the NCU 27 by a signal line 25 for gas flow communication. The NCU 27 and the communication interface circuit 17 form a transmission means. The control circuit 19 sends the input data stored in the memory to the NCU 27 as an electric signal when the item selection key SW ₁ and the data determination key SW ₄ are pressed at the same time after completing all the input operations. At this point, the gas appliance management data processing device A stops operating. The NCU 27 dials the telephone number of the management center 28, which is the information management facility of the gas supply company, which has been set in advance, and calls various input data together with the ID number of the user who has been set in advance by telephone line. It is transmitted to the host computer 30 installed in the management center 28 via the station 29.

The operation of the gas equipment management data processing device A thus configured will be described with reference to the flowcharts shown in FIGS. 8 and 9. First, by simultaneously pressing the item selection key SW ₁ and the data key SW ₃ (step S101), the gas equipment management data processing apparatus A is activated (step S103). The reason that the two keys SW ₁ and SW ₃ are simultaneously pressed for activation is to prevent the device from being activated unnecessarily due to mischief. After starting, the first input item is displayed on the liquid crystal display 15. For example, when the input item is a gas cylinder attachment, the liquid crystal display 15 displays “Tricket” indicating the attachment of the gas cylinder, the numeral “1” indicating the attachment of the first gas cylinder, and the cylinder as shown in FIG. A 4-digit blank symbol indicating the input position of the number is displayed (step S105).

Next, the process proceeds to the data input operation (step S107). As shown in FIG. 9, the data input operation is performed by pressing the data keys SW ₂ and SW ₃ to select an alpha bet or a numerical value for each digit (step S201) and pressing the data determination key SW ₄ to select. The operation of determining the alphabet and the numeral to be used (step S203) is repeated. Then, when the input operation of the number of the attached cylinder is completed (step S205) and the data determination key SW ₄ is pressed for 1 second or longer (step S207), the displayed input data is stored in the memory of the control circuit 19. (Step S209).

After inputting the data of the first mounting cylinder, as shown in FIG. 10B, the liquid crystal display 15 is provided with a display for data input of the second mounting cylinder. In this state, the data input operation of FIG. 9 is performed in the same manner as the first operation. Such data input operation is repeated until all mounting cylinders are completed. After completing the data input operation for all the attached cylinders, it is judged whether or not the item selection key SW ₁ has been pressed (step S109), and if so, the operation for inputting the number of the gas cylinder to be recovered is performed. In order to move, as shown in Fig. 10 (c), "Kaishu" indicating the collection of the gas cylinder, "1" indicating the collection of the first cylinder, and a 4-digit blank symbol indicating the input position of the cylinder number are displayed. (Step S111). After that, the operation shifts to the data input operation of FIG. 9, and the input operation is repeated until the item selection key SW ₁ is pressed, in other words, until the data input of all the cylinders to be collected is completed, similarly to the mounting cylinder. ..

Then, when the item selection key SW ₁ is pressed (step S113), as shown in FIG. 10D, in order to shift to the input operation of the safety inspection item of the supply facility which is the next input item, The liquid crystal display 15 displays each of "Setsubitenken" and a two-digit blank symbol (step S115). After that, the process shifts to the data input operation (step S107) in FIG. 9 and receives the code number of the defective inspection item. This input operation is performed by the delivery worker with reference to the inspection item table of FIG. Finally, when the item selection key SW ₁ and the data determination key SW ₄ are pressed at the same time (step S117), the input and stored data is sent to the NCU 27 as an electric signal (step S119). The NCU 27 to which the input data is sent dials the telephone number of the management center 28 and transmits various input data together with the ID number of the user to the host computer 30 via the telephone station 29 via the telephone line.

In this way, the management data of the gas equipment, such as the number of the gas cylinder that has been installed and recovered and the points of insufficiency in the safety inspection items of the supply equipment such as the gas cylinder fall prevention measures, are stored in the management center 28. When managed by the host computer 30, the delivery worker only needs to input predetermined data from the operation switch 13 provided on the microcomputer gas meter 1, so it is not necessary to carry around an input device such as a handy memory as in the conventional case. Instead, you can concentrate on the delivery work. Further, since the input data is automatically dialed and transmitted to the management center 28 side by the NCU 27 and processed in real time, no data processing work is required after the work is completed, the data processing is smoothly performed, and the dedicated data is processed. Since there is no need to allocate a data processor for the data, the cost is reduced accordingly. Further, even if the drive battery 21 is discharged, only one case cannot input data, and the work loss is reduced.

11 and 12 show a second embodiment of the present invention. This embodiment is a control circuit composed of a conventional microcomputer gas meter function, that is, a microcomputer having a safety monitoring function of a gas usage state such as detecting a gas flow rate and closing a built-in shutoff valve. In addition, the gas appliance management data processing device A shown in the above embodiment is also provided with the function. Specifically, as shown in the front view of the microcomputer gas meter 31 in FIG. 11, the liquid crystal display 33 displays the integrated value of the gas flow rate and the input data when the gas equipment management data processing device is used. Is possible. In addition, as shown in FIG. 12 as a schematic configuration diagram of the entire system including the gas equipment management data processing device, the microcomputer gas meter 31 and the NCU 27 are the input data signal and the gas flow rate in the gas equipment management data processing device. They are connected by a signal line 35 capable of transmitting both signals.

In this embodiment, the liquid crystal display 33 normally displays the gas flow rate, and when the item selection key SW ₁ and the data key SW ₃ are simultaneously pressed in this state, the liquid crystal display 33 functions as a gas equipment management data processing device. The liquid crystal display 33 functions and the integrated value display of the gas flow rate disappears, and the liquid crystal display 33 displays as a gas device management data processing device. When the input data is transmitted to the management center 28 side, the liquid crystal display 33 returns to the original integrated display. However, even when functioning as a gas equipment management data processing device, the gas flow rate is measured, and at the same time, a safety monitoring function such as the gas usage state is working, and when an abnormality occurs, this is processed preferentially. ..

With such a configuration, as in the first embodiment, the control circuit as the gas equipment management data processing device is also used as the control circuit having the function of the conventional microcomputer gas meter. The cost can be reduced as compared with the first embodiment.

In the first and second embodiments, the NCU 27 may be built in the microcomputer gas meters 1 and 31, respectively.

FIG. 13 shows a third embodiment of the present invention. In this embodiment, the gas equipment management data processing device including the operation switch 13, the liquid crystal display 15, the communication interface circuit 17, the control circuit 19 and the battery 21 shown in FIG. Connected to. With such a configuration, the gas device management data processing device can be installed at any position without depending on the installation position of the microcomputer gas meter, and operability can be improved.

[Effect of the device]

 As described above, according to the present invention, the management data of the gas equipment is input from the input means, and the input data is transmitted to the information management facility by the transmission means. Since it suffices to input predetermined management data from the input means on site, it is not necessary to carry an input device such as a handy memory as in the conventional case, and the work becomes easy. In addition, the input data is automatically transmitted to the information management facility and processed in real time, eliminating the need for data processing work after the work is completed, facilitating data processing, and providing dedicated data processing personnel. Since there is no need to distribute it, the cost can be reduced accordingly. Furthermore, even if the drive power is cut off in the middle of the process, data cannot be input only for that one case, which reduces work loss.
