Referring to FIGS. 1 and 2, a remote meter reading apparatus using wireless data communication and a wired network will be described. First, a pulse generator, which is a pulse generating means for generating a pulse signal according to the gas usage, is used for the gas meter 10 for remote meter reading. (Not shown) is provided, and the pulse generated from the pulse generator is detected by the pulse detector 12 and applied to the pulse signal processor 14. The pulse signal processing unit 14 removes the noise of the pulse, makes the pulse a sinusoidal wave, eliminates the chattering phenomenon, and counts it by the counting means. The count value counted by the pulse signal processing unit 14 is controlled by the storage means of the first control unit 18 and stored in the memory unit 16.

The first control unit 18 detects the clock generated from the clock circuit 18 by the meter determining means and determines whether the meter is the meter reading date for the gas meter 10. The first control unit 18 counts the number of clocks applied from the clock circuit 18 and determines the meter reading date if the counted value corresponds to the set value, and the meter reading stored in the memory unit 16 by the wireless transmission means. Data corresponding to the information (reading amount and unique number of the gas meter) is wirelessly transmitted to the data transmission unit 30.

Data transmitted through the wireless data transmitter 22 by the wireless transmitter of the remote meter reading gas meter 10 is received through the wireless data receiver 32 by the receiver of the data transmitter 30. Data received through the wireless data receiver 32 by the receiving means is stored in an auxiliary memory (not shown) under the control of the second controller 34. The data temporarily stored in the auxiliary memory by the auxiliary storage means is transmitted to the switching system 40 via the wired telephone network by the transmission means.

Referring to the remote meter reading method using a wireless data communication and a wired network according to an embodiment of the present invention, it is determined whether the pulse signal generated from the pulse generator is input (S10). When the pulse signal is input in the step S10, the pulse signal processor 14 counts the input pulse signal (S12). The count value counted in step S12 is stored in the memory unit 16 (S14). After the step S14, the clock signal applied from the clock circuit 18 is counted to determine whether or not a meter reading date is applied to the gas meter 10 (S16). In step S16, if it does not correspond to the meter reading date, the step S10 of determining whether a pulse signal is input is continued. If the meter reading date corresponds, the wireless data transmitter 22 wirelessly transmits meter reading information (S18). .

When the wireless data transmitter 22 of the remote meter reading gas meter 10 transmits the metering information in step S18, it is determined whether the meter data is received by the radio data receiver 32 of the data transmitter 30 ( S20). If the meter reading information is received in the step S20, data corresponding to the meter reading information received in the auxiliary memory is temporarily stored (S22). After the step S22, it is determined whether the hook of the wireline network is in an on state (S24). If the hook is turned on in the step S24, data corresponding to the meter reading information is transmitted to the switching system 40 through the DTMF TONE method (S26). The exchange system 40 classifies and processes data and transmits the data to the main computer 50 (S28), and the main computer 50 issues a notice to the user according to the data transmitted from the exchange system 40 (S30). )do.
