By the transmission control device 38 of the (500) via the public line (L) of the telephone It transmits to the support center C. 4 shows an operation flowchart of transmission control of an automatic dial.

First, in step 701, it is judged whether or not it is the transmission timing timer time at the time of meter reading in the automatic dial set for each house. In other words, since there is no need to send gas every hour during the meter reading, one house transmits the information to the information center (C) at 10:00 am on the first day of the month, and another house transmits at 10:05 am on the first day of the month. . The interval between the scheduled time of transmission of a house and another house is at least 5 minutes and is set between 1st and 28th of each month. In the present embodiment, when the gas leak setting report, which is abnormal information, is output, transmission can be performed at any time regardless of the transmission timing timer. When the transmission timing timer time is NO (NO) in step 701, step 701 is repeated. When it is the transmission timing timer time YES in step 702, it is judged whether or not the general subscription telephone T is in use (step 702). When in use (YES) in step 702, step 702 is repeated.

When not in use (NO), it is determined whether or not an incoming call is being made from a telephone outside the house (step 703). When calling (YES) in step 703, step 703 is repeated. When not in call (NO), the NCU 500 is converted to connect the public line L of the telephone and the IC 400 (step 704). Next, the DC line (not shown) in the NCU 500 is connected (ON) (step 705), and it is judged whether or not it has passed for 3 seconds thereafter (step 706). When 3 seconds have not elapsed (NO), step 706 is repeated. When 3 seconds have elapsed (YES), automatic dialing is performed to the information center C (step 707).

Next, it is judged whether or not the information transmission instruction signal (MF signal "#" in later) is received from the information center C (step 708). When it is received in step 708 (YES), the transmission form shown in Table 1 described later is transmitted based on the transmission protocol flow chart according to each regulation of the transmission control apparatus (step 709). Then, it is judged whether or not the information retransmission request signal (MF signal "#") is received from the information center C (step 710). When it is not received in step 710 (NO), it is determined whether or not the transmission form has elapsed 3 seconds after transmission (step 711).

In step 711, transmission control ends when 3 seconds have elapsed (YES), and when step 3 has not elapsed (NO), step 710 is repeated. When the information retransmission request signal is received from the information center C in step 711 (YES), it is judged whether or not the number of times of reception of the information retransmission request signal is applied (step 712). When it is not the second time (NO), the DC circuit is opened (step 713), and it is determined whether 5 seconds have elapsed thereafter (step 714). In step 714, step 714 is repeated when 5 seconds have not elapsed (NO), and when step 5 has elapsed (YES), step 702 or less is repeated again.

When the information transmission instruction signal is not received from the information center C in step 708 (NO), it is determined whether or not the number of reception times has been three times after the automatic dialing (step 715). In step 715, when it is not three times (NO), the DC circuit is opened (step 716), and it is then judged whether 5 seconds have elapsed (step 717). When 5 seconds have elapsed (YES) at step 717, step 702 or less is repeated again. When 5 seconds have not elapsed (NO), step 717 is repeated.

When the number of receptions reaches three times (YES) in step 715, it is determined whether 15 seconds have elapsed (step 718). When 15 seconds have not elapsed (NO) at step 718, the process proceeds to step 716. FIG. When 15 seconds have elapsed (YES) and when the number of reception times is YES at step 712, the DC circuit is opened (step 719). Next, it is determined whether automatic dialing is performed again (step 720). When automatic dialing is not performed again in step 720 (NO), it is determined whether 5 minutes have elapsed since the DC circuit was opened (step 721).

When 5 minutes have passed (YES) at step 721, step 702 or less is repeated again. When 5 minutes have not passed (NO), step 721 is repeated. After the automatic dialing is performed again in step 720 (YES), it is determined whether or not the recognition is performed after the third automatic dialing is performed (step 722). In step 722, when the third autodial is performed (YES), transmission control ends.

When the third automatic dial is not performed in step 722 (NO), it is determined whether 5 minutes have elapsed since the opening of the DC circuit (step 723). When 5 minutes have passed (YES) at step 723, the above step 702 or less is repeated, and when 5 minutes have not passed (NO), step 723 is repeated.

TABLE 1

TABLE 2

Table 1 shows the transmission format used for transmission control. In Table 1, all of the selection signals used in the transmission format are MF signals (multi frequency code). For example, numbers 0 to 9 and # and B symbols are used. At the time of receiving and transmitting the abnormality information, the gas meter reading, which is the meter reading information, is also transmitted.

The MF signal " B " at the left end of Table 1 is a Start of text, and since the " B "

The ID of Table 1 contains the user code number of six digits (0-9). As a result, the information center C can quickly determine which house the transmission signal is from. A delimiter "B" in Table 1 is shown at the end of a delimitation following the user number sent previously.

03 in Table 1 shows the relationship with the code number for each type of information. The code number is extracted from Table 2, and the number of two rows is entered. In this embodiment, data is provided for notifying that gas leakage has occurred in the house and for transmitting information on gas reading. The gas meter reading of Table 1 is a meter reading detected by the said automatic meter reading system of the said gas, and the number of 6 rows (any of 0-9) enters. When the sensor group 1 detects the abnormality information and does not depend on each timer at the time of transmission timing, the meter reading of the gas is simultaneously transmitted. The CK (Character Check Code) shown in Table 1 contains only the first number (any of 0 to 9) of the number obtained by counting all the numerical information in the above transmission. Here, the CK is used to detect an error of the transmission information. For example, when the data is B123456B03123456CK ##, the CK = 5, that is, 1 + 2 + 3 + 4 + 5 + 6 + 0 + 3 + 1 + 2 + 3 + We use the number 5 of units at 4 + 5 + 6 = 45. The right end "##" symbol in Table 1 is an end text, indicating the end of information transmission.

Here, after the transmission form Table 1 is transmitted to the information center C (after receiving the start text signal), the information retransmission request signal is sent to the terminal device 100 in the case of a transmission form error or a MF signal error. If there is a mistake after receiving the division code, the information retransmission request signal is sent within 2 seconds. If no code is received, the information retransmission request signal is transmitted within 2.5 seconds. If another code is received without receiving the information start code, it is determined as invalid information and the DC circuit is opened. The number of requests for retransmission of information shall be twice.

In the present embodiment, the public line of the telephone is used as the transmission path when the information is transmitted from the terminal apparatus to the information center, but other communication lines or radios via satellites may be used.

In this embodiment, a lithium battery is used as the power source, but a home AC power source (100 V 50/60 Hz) may be used.

In this embodiment, the metering unit may be assembled to the general subscription telephone. In addition, a display device such as a lamp or a buzzer may be attached to the meter reading unit when a general subscription telephone is used or when the sensor group is output.
