Abstract

The system for determining domestic consumption of electricity, heat, water and gas includes: a number of measuring units (2) for measuring consumption of electricity, heat, water and gas; a concentration unit (4) connected to the measuring units (2) to acquire consumption data from the measuring units (2) and transmit the consumption data via radio; a mobile collecting unit (6) for collecting consumption data transmitted by the concentration unit (4); and a remote central processing unit (8) for collecting and processing the consumption data supplied by the mobile collecting unit (6).

Claims

1. A system for determining consumption, characterized by comprising:

a number of measuring units (2) for measuring consumption of at least one quantity selected from electricity, heat, water or gas;

each of said measuring units comprise a prepayment interface for interacting with a chip card containing memorized user identification data and a memorized sum prepaid by a user;

a concentration unit (4) connected to the measuring units (2) to acquire consumption data from the measuring units (2) and selectively transmit the consumption data via one of radio and a hard-wired data communication network;

a mobile collecting unit (6) for collecting the consumption data transmitted by the concentration unit (4); and

remote processing means (8) for collecting and processing the consumption data supplied by at least one of the mobile collecting unit (6) and the concentration unit (4),

whereby said user is prevented from consuming said at least one quantity selected from electricity, heat, water or gas until said chip card interacts with said prepayment interface.

2. A system as claimed in claim 1, characterized in that each of said measuring units (2) comprises:

measuring means (10) for continuously determining consumption data relative to consumption of said quantity;

first line receiving and transmitting means (16) for transmitting said consumption data and identification data identifying the measuring unit (2) to said concentration unit (4) over electric lines; and

first memorizing means (22) for memorizing said consumption data.

3. A system as claimed in claim 2, characterized in that each of said measuring units (2) also comprises:

programming interface means (18) for connection to an external programming unit (60).

4. A system as claimed in claim 2, characterized in that each of said measuring units (2) also comprises:

display means (14) for displaying consumption data; and

enabling means (12) for enabling said display means (14).

5. A system as claimed in claim 1, characterized in that said concentration unit (4) comprises:

second line receiving and transmitting means (30) for transmitting instructions to said measuring units (2), and for receiving said consumption data and said identification data identifying the measuring units (2) transmitted by said measuring units (2) over electric lines;

second memorizing means (36) for memorizing the received said consumption data and said identification data; and

first radio receiving and transmitting means (32) for receiving an incuiry signal from said mobile collecting unit (6) and transmitting said consumption data and said identification data over a radio channel to said mobile collecting unit (6) in response to said inquiry signal.

6. A system as claimed in claim 5, wherein said hard-wired data communication network defines a first communication interface means (34) for communicating with said remote processing means (8) to exchange data and instructions via said hard-wired data communication network in addition to said radio.

7. A system as claimed in claim 5, characterized in that said concentration unit (4) also comprises:

radio transmitting means (35) for transmitting a signal containing information concerning the position of said concentration unit (4).

8. A system as claimed in claim 1, characterized in that said mobile collecting unit (6) comprises:

a vehicle (40); and

a device (41) for radio transmitting an inquiry signal to said concentration unit (4), and for receiving and memorizing the consumption data and identification data radio transmitted by the concentration unit (4) in response to said inquiry signal.

9. A system as claimed in claim 8, characterized in that said device (41) comprises:

second radio receiving and transmitting means (42) for transmitting an inquiry signal over a radio channel to said concentration unit (4), and for receiving the consumption data and identification data transmitted by the concentration unit (4) in response to said inquiry signal; and

third memorizing means (48) for memorizing the received said consumption data and said identification data.

10. A system as claimed in claim 9, characterized in that said device (41) also comprises:

second communication interface means (43) for transmitting said consumption data and said identification data to said remote processing means (8).

11. A system as claimed in claim 9, characterized in that said device (41) also comprises:

second display means (46); and

first data entry means (44).

12. A system as claimed in claim 3, characterized in that said external programming unit (60) comprises:
