Fig. 2 is embodiment 1 circuit control principle figure of the present utility model.
Fig. 3 embodiment 2 circuit control principle figure of the present utility model.
Fig. 4 is the utility model embodiment 3 circuit control principle figure.
Among the figure: 1, bolt, 3, nut, 4, pad, 5, pressure sensor
The specific embodiment
Information acquisition unit is a pressure sensor, and pressure sensor is arranged between the nut and pad of automotive wheel binding bolt, the input end of its output termination signal processing unit.
As shown in Figure 1: on automotive wheel, bolt 1 passes the tapped bore on the wheel, and is fixing by nut 3 again, is provided with pad 4 between bolt 1 and nut 3, and the pressure sensor 5 as the information acquisition unit of native system is installed between nut 3 and the pad 4.
Signal processing unit is for amplifying the signal of pressure sensor amplifier and the A/D converter with digitized processing, the mouth of amplifier input terminal and sensor communicates to connect, the output termination A/D converter of amplifier, the digital signal output end of A/D converter connects control unit.
Information acquisition unit adopts the micro capacitance pressure sensor, integrated thereon the amplification and the A/D converting unit, be installed in together between nut 3 and the pad 4, the output digital signal, because the amplification and the A/D converter of signal are integrated in one, avoid outside electromagnetic interference, sensitivity is better than traditional sensor, thereby obtains information more accurately.
Control unit is a micro controller system, and micro controller system links to each other with the digital signal output end of the A/D converter of signal processing unit.
Performance element comprises warning, brake system and indicating member, and corresponding with the micro controller system respectively delivery port of the control end of warning, brake system and indicating member links to each other.
Because, capacitive pressure transducer need rotate with automotive wheel, therefore, adopt radio communication between micro controller system and the micro capacitance pressure sensor in the present embodiment, be provided with wireless signal transmitting device in sensor one side, be provided with radio receiver in micro controller system one side, will be sent in the micro controller system by the number pressure that sensor one side is collected.In micro controller system, handle, if pressure is too little or too big, the side control warning sound or, send indicator signal by indicating member, allow chaufeur handle, perhaps by automobile brake system with the car processing of stopping.
Embodiment 2 is as shown in Figure 3: present embodiment sensor mounting means is with embodiment 1, at this moment, when bolt 1 and nut 3 under tightening state, pressure sensor 5 amplifies by lead the pressure signal of gathering by amplifier, flowing to micro controller system after signal after will amplifying is again changed by A/D converter handles, micro controller system is after judging the signal after the conversion, determine to be between the screw bolt and nut tightening state, pressure sensor output be normal signal the time, then the indicator lamp in the indicating member is shown as green light.If have loosening between the screw bolt and nut, pressure sensor is no longer by pressurized, in the time of can't collecting pressure signal, micro controller system this moment can't picked up signal, when perhaps obtaining more weak signal, in time the indicator lamp in the control indicating member be red, and starts warning prompting chaufeur and stop immediately and check.Perhaps under urgent situation by the brake system of micro controller system direct control automobile own or ignition device, make it flame-out, allow car stop immediately, to guarantee chaufeur and Che Nei passenger's safety.
