Detailed Description
The technical solution of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention, and the following embodiments are only some, but not all embodiments of the present invention. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention.
Referring to fig. 1 and fig. 2, for the embodiment of the present invention provides a basic structure schematic diagram and a circuit principle schematic diagram of an anti-dismantling intelligent gas meter. The utility model discloses a prevent tearing open intelligent gas table includes: the gas meter comprises a shell 1 of the gas meter, an upper cover 2, a PCB main control circuit board 3, a base 4, a photosensitive element 5, a light emitter 6, a light receiver 7, a central processing unit 8, a wireless communication module 9 and a valve control module 10.
Specifically, the PCB main control circuit board 3 is fixed on the base 4; the light emitter 6 is arranged on the inner side of the upper cover 2; the photosensitive element 5 and the optical receiver 7 are arranged on the PCB main control circuit board 3; the central processing unit 8, the wireless communication module 9 and the valve control module 10 are also installed on the PCB mainboard 3; the CPU 8 is used for determining whether there is a table-detaching action, the wireless communication module 9 is used for sending an abnormal message, and the valve control module 10 is used for controlling the closing of the valve. The base 4 is installed in the shell 1; the upper cover 2 is fixed on the housing 1.
Referring to fig. 1, the optical transmitter 6 corresponds to an installation position of the optical receiver 7, and the optical receiver 7 receives an optical signal transmitted by the optical transmitter 6.
Referring to fig. 1, the photosensor 5 is located at a certain distance from the light emitter 6, the photosensor 5 cannot receive the light signal emitted by the light emitter 6, and the photosensor 5 can only receive the light signal of an external light source.
The photosensitive element 5 is a sensor which converts an optical signal into an electrical signal by using the photosensitive element 5, and judges the action of detaching the meter by sensing the change of an external optical fiber. The method specifically comprises the following steps: in a normal working state of the utility model, the upper cover 2 is sealed with the shell 1, the photosensitive element 5 in the gas meter can not sense light, and no light signal is generated; when the watch is detached, the upper cover 2 is separated from the shell 1, the photosensitive element 5 detects external light, the change of the physical quantity of the photosensitive element 5 can be caused, and the circuit transmits the change to the central processing unit 8, so that the aim of detecting the external light is fulfilled.
