If number of patent application is the fuel tank truck manhole of CN201611206578.8 and its port lid open detection device, in port lid top board Travel switch is set between lower platen, its travel switch sends out switching signal when top board or lower platen are opened.But stroke Switch is a kind of mechanical switch, and in top board or the small unlatching of lower platen, small displacement is also not enough to cause switch shape The variation of state, and top board or the small unlatching of lower platen have been enough the manual priming from manhole, have stolen oil, detection sensitivity It is low, anti-theft performance is poor.
Invention content
The purpose of the present invention is in view of the shortcomings of the prior art, provide the tool that a kind of detection sensitivity is high, anti-theft performance is good There is the manhole cover of aperture monitoring device.
Technical scheme of the present invention includes cover, manhole, top board, lower platen, and manhole is arranged in cover in plane, on Pressing plate and lower platen are mounted in manhole, and monitoring device is set between top board and cover;Mainly monitoring device is using suddenly That electromagnetic induction sensor, the Hall electromagnetic induction sensor is by babinet, case lid, displacement transformation mechanism, permanent magnet and Hall Element forms;Babinet is fixedly mounted in cover in plane, the input terminal of displacement transformation mechanism and the rotation axis connection of top board, Output terminal is fixedly connected with permanent magnet;Hall element is mounted on the cabinets cavity of permanent magnet end face side, in Hall element side Installation signal processing apparatus in babinet;The signal processing apparatus is made of proportional amplifier, positive input terminal by resistance with Hall element output terminal connects, and negative input end is connect by divider resistance with working power negative terminal, in negative input end and output terminal Between connect adjustable resistor, connect the first filter condenser between output terminal and working power negative terminal, positive input terminal and work The second filter condenser is connected between power supply negative terminal.
Preferably, displacement transformation mechanism is made of runner, axis pin, connecting plate and sliding block, the rotation center of runner and upper pressure The rotary shaft end of plate is fixedly connected, and axis pin one end is mounted on runner in the plane at outer circle, and the axis pin other end is with connecting The pin hole of plate one end moves cooperation, and cooperation is moved in the axis hole of the connecting plate other end and one end of fixing axle, and sliding block one end, which is mounted on, to be fixed On axis, sliding block both sides are inlaid in sliding slot made on babinet and cover wall,.
It is an advantage of the invention that monitoring device uses the Hall electromagnetic induction sensor being made of permanent magnet and Hall element, When top board is opened, rotary shaft drives runner, axis pin and the connecting plate rotation that one end is connect with axis pin, and connecting plate is another End pulls sliding block to move linearly in cabinets cavity wall sliding slot by fixing axle, makes the distance between permanent magnet and Hall element hair Changing changes hall element output voltage, obtains intellectual monitoring signal by signal processing apparatus and microprocessor, has inspection Survey high sensitivity, the features such as anti-theft performance is good.
