Detailed Description
The following description of the preferred embodiment of the present invention will be given with reference to fig. 1, so that the function and features of the present invention can be better understood.
Referring to fig. 1 to 4, an embodiment of the present invention includes a tamper-proof wireless remote diaphragm gas meter, which includes a housing 1. The shell 1 is provided with an opening, an upper cover 2 is arranged at the opening, and the upper cover 2 is used for shielding a circuit board 3 in the shell 1. The circuit board 3 is arranged in parallel with the inner surface of the upper cover 2, the front surface of the circuit board 3 facing the inner surface of the upper cover 2.
In order to avoid the upper cover 2 from being deliberately disassembled, a lateral pressure type key 4 is arranged in the shell 1, and a probe 5 is arranged on the inner surface of the upper cover 2, wherein the position relationship between the upper cover 2 and the probe 5 is satisfied that when the upper cover 2 is arranged on the shell 1, the probe 5 presses the lateral pressure type key 4 from the side, and when the upper cover 2 is normal, the lateral pressure type key 4 is in a normally closed state.
When the upper cover 2 is detached, the probe 5 is separated from the lateral pressure type key 4, and whether the upper cover 2 is detached can be monitored by monitoring the state of the lateral pressure type key 4. In some embodiments, the circuit board 3 is provided with a controller (integrated on the circuit board, not shown) connected to the side pressure key 4 and a motor valve 6 connected to the controller. The side pressure type key 4 is also not shown in fig. 3 and 4.
The controller is configured to send out a disassembly alarm signal when the side pressure type key 4 is sprung up, and control the motor valve 6 to be closed. The motor valve 6 is connected between the air inlet pipe and the air outlet pipe, and the gas meter can not normally use gas when the motor valve is closed, so that the safety of a gas meter pipeline system is ensured, meanwhile, the gas is prevented from being stolen, the supply and sales difference can not be generated, and a gas company can not have loss.
The controller is connected with the wireless communication module, and when detecting that upper cover 2 is taken apart through side pressure formula button 4, upload to gas meter management platform through wireless communication module, gas company can in time receive this gas meter and receive the information of tearing open the machine for gas company can in time master the state information that the gas meter was torn open the machine. In this embodiment, the operation logic of the controller is simple, and only one switching signal and one fixed digital signal sequence need to be generated according to the state of one key, so that the method can be implemented by adopting a simple digital logic circuit, special software is not needed, and the improvement of the method is not involved.
In some embodiments, the side pressure type key 4 and the controller are provided on the back surface of the circuit board 3 (the circuit board 3 is directed toward the upper cover 2). The side-pressing key 4 has a key shaft 7 extending in a direction parallel to the circuit board 3. The front surface of the circuit board 3 faces the upper cover 2, the circuit board 3 is provided with through holes corresponding to the key shafts 7, and the through holes 8 are used for the probes 5 to penetrate through so as to press the key shafts 7 of the side press type keys 4.
To further improve the safety, in a specific embodiment, the shape of the through hole on the circuit board 3 is adapted to the cross-sectional shape of the probe 5. The ratio of the width d of the key shaft 7 to the width at the narrowest point of the cross-sectional shape of the probe 5 is less than 1:2. The arrangement positions of the side press keys 4 are randomly selected around the through holes of the circuit board 3 and are satisfied that the probes 5 press the key shafts 7 of the side press keys 4 when the upper cover 2 is mounted on the housing 1. As shown in fig. 5, a1, a2, a3 around the through hole 8 are all optional positions of the side pressure type key 4. Fig. 2 shows the key shaft 7 when not pressed. During the pressing, the key shaft 7 is contracted along its axis toward the inside of the main body of the side pressure type key 4 until the end of the key shaft 7 is flush with the side of the main body of the side pressure type key 4.
In some embodiments, the through hole 8 on the circuit board 3 is circular, and the cross section of the probe 5 is also circular 2, and the two can form a clearance fit. In this case, the side pressure type key 4 may be arbitrarily selected along the circumferential direction. The circular through-hole 8 allows a larger range of optional installation of the side pressure type key 4 than the square through-hole 8.
The installation position of the lateral pressure type key 4 is randomly selected, and the lateral pressure type key 4 is arranged on the back of the circuit board 3, so that the position of the key shaft 7 can not be observed by the disassembling robot, and the situation that the disassembling robot uses objects such as sheets and the like to take targeted measures according to the position of the lateral pressure type key 4 in the disassembling process is avoided. The adoption of the key shaft 7 with a narrow width makes it difficult for the dismantling robot to block the rebound of the key shaft 7 according to the position of the key shaft 7.
In addition, in this embodiment, the lateral press key 4 adopts a smaller trigger stroke (the trigger stroke refers to that the lateral press key 4 is disconnected by a smaller rebound distance of the key shaft 7), so that even if the probe 5 is inserted into the through hole 8 in the disassembling process, the posture of the probe 5 is difficult to keep unchanged, the lateral press key 4 is disconnected by slight swing of the probe 5, and the disassembling difficulty is increased.
In some embodiments, the probe 5 is perpendicular to the inner surface of the upper cover 2; the end of the probe 5 is wedge-shaped or conical, and the inclined surface of the end of the probe 5 is used for pushing the key shaft 7 of the side pressure type key 4 to shrink.
The present invention has been described in detail with reference to the embodiments of the drawings, and those skilled in the art can make various modifications to the invention based on the above description. Accordingly, certain details of the illustrated embodiments are not to be taken as limiting the invention, which is defined by the appended claims.
