Abstract

A number of remote terminals are connected to various utility meters to store the readings therein. A central terminal sequentially transmits signals to the remote terminals to actuate the same to transmit the meter readings to the central terminal. Each remote terminal comprises storage units to store the readings of the meters respectively. Each storage unit is designed to store the number of digits required for the meter reading, and also a code digit which indicates the type of meter (gas, electric, etc.) or instructions (skip to next meter, remote terminal address, user number, etc.). The code digit is transmitted as if it were a part of the meter reading. A connector card is insertable into a receptacle to detachably set the codes into the storage units of the remote terminals.

Claims

1. A utility meter reading system comprising:

a remote terminal having a plurality of storage means respectively connected to utility meters and adapted to store meter readings of the utility meters therein, each of the storage means respectively having a predetermined number of meter reading storage elements for storing the meter readings and a code storage element for storing a code;

a central terminal;

communication link means connecting the central terminal to the remote terminal;

the central terminal being operative to transmit storage means selection signals to sequentially energize the storage means and storage element selection signals to sequentially actuate the storage elements of an energized storage means, whereby the central terminal is operative to sequentially actuate the meter reading and code storage elements of the remote terminal to transmit the meter readings and the code to the central terminal;

decoder means adapted to receive the storage means and storage element selection signals, the decoder means having outputs connected to enable inputs of the storage elements of the storage means; and

code setting means for reversibly setting the codes into the code storage elements of the storage means, said code setting means comprising a receptacle having terminals connected to the code storage elements and a connection member detachably insertable into the receptacle, the connection member being adapted to connect desired terminals of the receptacle together and thereby set the codes into the code storage elements.

2. The utility meter reading system of claim 1, in which the receptacle comprises input terminals connected to outputs of the decoder means and output terminals connected to outputs of the storage elements of the storage means.

3. The utility meter reading system of claim 2, in which the input terminals of the receptacle are constituted by first elongated parallel conductors and the output terminals of the receptacle are constituted by second elongated parallel conductors, the first elongated parallel conductors being arranged perpendicular to the second elongated parallel conductors, the connection member being constituted by a card formed of an electrical insulating material with electrically conducting members extending therethrough to connect desired input terminals to desired output terminals.

4. The utility meter reading system of claim 1, further comprising a data terminal having a plurality of storage means and code setting means identical to the storage means and code setting means of the remote terminal, all of the storage elements of the data terminal being adapted to store data required in the utility meter reading system, the central terminal being operative to sequentially actuate the storage elements of the data terminal in an identical manner as the storage elements of the remote terminal.

5. The utility meter reading system of claim 4, in which the central terminal comprises a printer to print out data in the data terminal and the meter readings in the remote terminal.
