Abstract

A monitoring apparatus for tanks and the like, comprising detecting means (4; 506) to detect the filling level of a tank, detecting means (5, 106; 206) to detect the opened and closed states of opening/closing means (6) of said tank, and gathering and processing means (106) to gather and process the detected data, characterized in that said processing means (106) are integrated with an RFID unit (116) which can communicate said data with at least one appropriate remote transceiver unit (7).

Claims

1. A monitoring apparatus for a tank or the like, comprising

detecting means (5, 106;

206;

17, 101) to detect the opened and closed states of opening/closing means (10;

6) of said tank, and

gathering and processing means (1;

106) to gather and process the detected data,

wherein

said gathering and processing means (106;

1) are integrated with an RFID unit (116;

221) which communicates said data with at least one suitable remote transceiver unit (7).

2. The apparatus of claim 1, wherein said detecting means for the state of said opening/closing means comprise an RFID unit (5) which is arranged near said tank and which communicates with said RFID unit (116) integrated into said processing means (106), the said processing means (106) being arranged in said opening/closing means (6) of said tank, and provided with powering means (306).

3. The apparatus of claim 1, wherein said detecting means for the state of said opening/closing means (6) of said tank comprise sensing means (206;

17, 101) which are positioned on said opening/closing means (6;

10), the said processing means (106) being arranged in said opening/closing means (6;

10) of said tank, and provided with powering means (401;

306).

4. The apparatus according to claim 3, wherein said opening/closing means comprise a filler cap (6;

10) comprising two portions (11, 12) which are coupled to each other and can be in relative motion with each other, said relative motion being associated with the opened or closed state of said filler cap.

5. The apparatus of claim 4, wherein said gathering and processing means (1;

106) is positioned within one of said portions (11, 12) of said filler cap (10).

6. The apparatus of claim 5, wherein one of the said portions is provided with a permanent magnet, and said sensing means comprises a Hall effect sensor (206).

7. The apparatus of claim 5, wherein said portions (11, 12) are coupled to switching means (101, 17) which can switch on or switch off a circuit component of the powering circuit (401) of said processing means (1), said circuit component being adapted to modify the electrical features of the power supply for said processing means (1).

8. The apparatus of claim 7, wherein said portions (11, 12) of said filler cap (10) are provided with blocking means (13, 16, 14, 15) to block said relative motion, said blocking means (13, 16, 14, 15) being arranged to securely and detachably block said portions (11, 12) in positions which correspond to the opened and closed states of said filler cap (10) respectively.

9. The apparatus of claim 7, wherein said switching means comprise two contacts (101) which are arranged on one of said portions (11), said contacts cooperating with a metal plate (17) which is arranged on the other portion (12).

10. The apparatus of claim 7, wherein said circuit component adapted to modify the electrical features of the power supply for said processing means (1) is a resistor (501).

11. The apparatus of claim 1, wherein said apparatus further comprises detecting means (4;

506) for the filling level of the tank.

12. The apparatus of claim 11, wherein said detecting means for the filling level of the tank comprise means (4) which is positioned inside the tank itself and communicates with said RFID unit (116) integrated into said processing means (106) through an RFID unit (5) which is connected to said means (4).

13. The apparatus of claim 11, wherein said detecting means for the filling level of the tank comprises sensing means (506) arranged in said opening/closing means of the tank, said sensing means being connected to said processing means (106).

14. The apparatus of claim 13, wherein said sensing means (506) to sense the filling level and said sensing means (206) to sense the state of said opening/closing means are connected to said processing means (106) through a multiplexer (606).

15. The apparatus of claim 11, wherein said tank is a fuel tank of a motor vehicle, said motor vehicle being provided with an electronic control unit (20) in communication with suitable peripheral devices (3, 4) through a suitable CAN/LIN network (2), an RFID card (5) being provided with an interface (105) to said network, said interface being able to communicate with said RFID unit (116) integrated into said processing means (106).
