Embodiment Construction

[0019] According to the attached figure 1 , give a preferred embodiment of the present invention, and give a detailed description, so that the functions and characteristics of the present invention can be better understood.

[0020] see Figures 1 to 4 As shown, the embodiment of the present invention includes a tamper-proof wireless remote transmission membrane gas meter, which includes a housing 1 . The casing 1 is provided with an opening, and an upper cover 2 is installed at the opening, and the upper cover 2 is used to shield the circuit board 3 inside the casing 1 . The circuit board 3 is arranged parallel to the inner surface of the upper cover 2 , and the front of the circuit board 3 faces the inner surface of the upper cover 2 .

[0021] In order to prevent the upper cover 2 from being intentionally disassembled, a side-press button 4 is provided inside the housing 1, and a probe 5 is provided on the inner surface of the upper cover 2. The positional relationship be...

Abstract

The invention provides an anti-disassembly wireless remote transmission diaphragm gas meter. The anti-disassembly wireless remote transmission diaphragm gas meter comprises a shell and an upper coverarranged at an opening of the shell, wherein a probe is arranged on the inner surface of the upper cover, and a side pressing type key is arranged in the shell; the position of the side pressing typekey meets the condition that when the upper cover is arranged on the shell, the probe presses the side pressing type key; a controller connected with the side pressing type key and a motor valve connected with the controller are arranged in the shell; the controller is configured to send out a disassembly alarm signal and control the motor valve to be closed when the side pressing type key bouncesup. By means of the structure of the high-sensitivity and high-reliability side pressing type key and the probe, the wireless remote transmission function of the controller and the function of controlling the built-in motor valve are combined, and thus a gas company can master the state of the gas meter in time.

Description

technical field [0001] The invention relates to the field of sensor instruments, in particular to an anti-demolition wireless remote transmission membrane gas meter. Background technique [0002] Membrane gas meter—mainly used for user terminal metering of civil and industrial pipeline natural gas. The gas meter body usually has a seal structure to prevent users from dismantling the meter, or leaving traces of disassembly in the case of malicious demolition. At present, the traditional gas meter anti-dismantlement in the industry mainly adopts mechanical lead seals, and this method has been continued to wireless remote transmission membrane gas meters. There are many disadvantages in this method: for example, the gas meter cannot be found in time after being dismantled, and the timeliness is very poor; gas leakage may be caused after dismantling, which affects the safety of gas consumption; data may be tampered with after dismantling, affecting the poor supply and marketing...
