である。Description: BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention
The present invention relates to a so-called automatic meter reading system for acquiring meter information such as gas, electricity, and water. 2. Description of the Related Art A conventional automatic meter reading system generally uses a telephone line from a communication center to call an automatic meter reading meter to acquire meter information. [0003] For this reason, if there is a trouble in the telephone line or the telephone exchange facility, it becomes difficult to call the automatic meter reading meter from the communication center side and acquire the meter information. Therefore, conventionally, a retry is performed after a while, and if communication is still not possible, a meter reader goes to a customer and performs meter reading. Therefore, when a trouble occurs in a telephone line or the like, labor is required. [0004] In addition, when the telephone number of the customer is changed, there is no problem if this change notification is sent immediately.
Usually, there are many delays, and sometimes there is no notification. In this case as well, it becomes impossible to obtain meter information by telephone, so that meter reading must be performed manually. SUMMARY OF THE INVENTION The object of the present invention is to solve the above-mentioned problems, and the structure thereof is as follows. In the automatic meter reading system that calls the customer's automatic meter reading meter from the communication center using a telephone line and acquires the meter information recorded in this automatic meter reading meter, a communication monitoring circuit and a self-calling circuit are provided on the automatic meter reading meter side. The communication monitoring circuit monitors whether or not the meter information has been transmitted from the automatic meter reading meter in response to a call from the communication center side, and if the transmission has not been performed, drives the self-originating circuit. Automatic meter reading system that calls the communication center side from the meter reading side and sends meter information. The normal automatic meter reading obtains meter information by calling the automatic meter reading meter from the communication center side. This communication is performed, for example, every month at the same time on the same day. The communication monitoring circuit on the automatic meter reading meter checks whether there is a call this month and whether or not the meter information has been transmitted.If the call and the transmission of meter information have not been performed, the self-originating circuit is driven. Call the communication center from the automatic meter reading side and transmit the meter information. FIG. 1 is a conceptual diagram of an automatic meter reading system embodying the present invention. 1 is a communication center, 2 is a transmission control system, 3 is a reception control system, 4 is a transmission telephone line, 5 is a reception telephone line, 6 is a telephone office, 7 is a terminal telephone line, 8 is a T-NCU, and 9 is a T-NCU. The telephone 10 is an automatic meter reading meter. The automatic meter reading device 10 records, for example, data such as an integrated flow rate of gas used for one month and a gas use state. Reference numeral 11 denotes a transmission circuit for transmitting meter information in the automatic meter reading meter 10 in response to a call from the communication center 1, 12 a communication monitoring circuit for monitoring the transmission status of the transmission circuit 11, and 13 a communication monitoring circuit. Reference numeral 12 denotes a spontaneous call circuit that drives the transmission circuit 11 to call the communication center 1 and automatically transmit the meter information when it is confirmed that the call of this month and the transmission of the meter information are not performed. As described above, according to the present invention, when the meter information is not obtained from the communication center side for some reason,
The meter reading side calls the communication center by the self-calling method and transmits the meter information, so even if there is a trouble in the telephone line or the telephone number is changed as before, it is necessary to perform the meter reading work manually. Disappears. Therefore, it is possible to improve the meter information collection rate and reduce the meter reading cost.
