Next, the operation will be explained. In the current automatic meter reading system, a center dials the relevant user and establishes a communication line, but if no action is taken, the user's phone will ring when a call is received. In order to prevent this, a so-called "No-Ringing" method has been devised. For this reason, when automatic meter reading is performed, the procedure is roughly as follows. NCU 3 for the center that receives instructions from the automatic processing device 31 or 31 of the center 30
2, the NRT 35 once connected to the user side exchange 4
sends the phone number it has. This communication route is 31,3
2, 36, 33, 37, 34, 38, 35, and N
RT35 recognizes the phone number sent as one for automatic meter reading. Next, the center confirms the transmission approval signal sent back from NRT, and then sends the phone number of the user to whom the meter is being read,
Sends NCU selection number, etc. The exchange 34 that received the contact from NRT connects the telephone line 11 of the received number,
After slowly reversing the voltage polarity of the telephone line, No-R
The NCU 14 within the user is called without ringing the telephone bell with the calling signal. This NCU1
4 returns a response, a line between the center and the user NCU is set up, data communication begins, and the center receives the value of the automatic meter reading meter 12 and stores it in the automatic processing device 31.

The operational flow of the system of the present invention will be explained with reference to FIG. 1. When the specified meter reading date is reached,
The user NCU transmits a meter reading command 1 to the automatic meter reading meter to transmit a measured value, and the automatic meter reading meter returns meter reading data 2. The user NCU memorizes this, and when the predetermined time arrives, it confirms that the user is not busy, automatically dials the predetermined center's telephone number, and connects the line to the center via the central office exchange. do. If communication is possible, the center transmits a transmission command 4 to the user NCU. Upon receiving the transmission command 4, the user NCU transmits meter reading data 5 and the like to the center. Next, the center examines the data content 5 received from the user NCU, and if it is good, sends that fact, the next meter reading date and transmission time, and if necessary, the interim contact date etc. to the user NCU in step 6. . When the user NCU receives 6, it sends a reply of acknowledgment to the center in 7, completing the series of transmission and reception.

FIG. 2 shows a functional block diagram of the user-side NCU 14 for realizing the system operation flow shown in FIG. A switching unit 15 is connected to the user (subscriber) line 11,
It is connected to the telephone 13 using the telephone cord 22. Switching section 15
is normally connected to the telephone side, and switches to the transmitting section 18 and receiving section 19 when transmitting/receiving meter reading data. 16 is an automatic processing unit, which automatically processes meter reading meter 1 at the time specified by the center.
2, the meter reading values are received and stored in the memory via connection lines 20 and 21, and the meter reading data is transmitted at a predetermined time.The data received from the center is also checked here, and if the line is disconnected while the meter reading data is being sent or received. If there is, the automatic dialing unit 17 is restarted to restore the line. Reference numeral 17 denotes an automatic dialing section, which performs automatic dialing to the center based on instructions from the automatic processing section 16. 18 is a transmitting unit, which transmits the telephone number and meter reading data. Reference numeral 19 denotes a receiving section, which receives telephone line connections and data from the center and transmits it to the automatic processing section. Arrows in the figure indicate the direction of flow of data, etc. Note that the hardware of the equipment in the center 30 in Figure 3 enables standby reception, and the software allocates transmission time so that transmissions from multiple users do not overlap, and sends information such as the next meter reading date. When necessary, contact the user NCU.
