Specific embodiment
For the ease of using, the embodiment of the invention provides TMR magnetic resistance sensor proof mechanisms.Below in conjunction with this hair
Attached drawing in bright embodiment, technical scheme in the embodiment of the invention is clearly and completely described, it is clear that described
Embodiment is only a part of the embodiment of the present invention, instead of all the embodiments.Based on the embodiments of the present invention, this field
Those of ordinary skill's every other embodiment obtained without making creative work, belongs to protection of the present invention
Range.
Embodiment 1
Fig. 1-5 is please referred to, TMR magnetic resistance sensor proof mechanism, including anti-clipping system 1, anti-clipping system 1 are present embodiments provided
It include isolation shaping circuit 11, display circuit 10, warning circuit 9 and single-chip microcontroller 2, the signal input port connection of single-chip microcontroller 2
There are TMR speed probe 8, TMR current sensor 6 and infrared scan inductor 3, the signal output port of single-chip microcontroller 2 is connected with
The signal output port of relay 4, relay 4 is connect with motor 5, and motor 5 includes rotor 7, and motor 5 is fixed by mounting plate
It is located at doorframe top side wall, motor 5 is connected with transfer roller 13, and the top side wall of the other end of transfer roller 13 and doorframe is rotatablely connected,
Anti-theft shutter 12 is wrapped on transfer roller 13, buffer board 14, infrared scan is fixedly mounted in the bottom face level of Anti-theft shutter 12
Inductor 3 is equipped with several, and uniform intervals are embedded in the upper surface of buffer board 14 respectively.
In the present embodiment, in order to not only be able to achieve pinch resistant functionality, but also it can be existed with final plant closure automatically-controlled door by anti-clipping system 1
Two sections are divided within the scope of from top dead-centre to bottom dead centre in section:
One, the non-anti-clip area of Intelligent cargo cabinet electrically operated gate: from automatically-controlled door top dead-centre to following a certain range (the non-anti-pinch of general automatically-controlled door
Area is automatically-controlled door top dead-centre to following 10mm or so), barrier, motor are encountered when even if Anti-theft shutter 12 rising in the region
5 will not invert, can stop when guaranteeing that Anti-theft shutter 12 encounters the automatic door guide rail adhesive tape on the doorframe of upside rather than anti-
Turn；
Two, the anti-clip area of Intelligent cargo cabinet electrically operated gate, the region other than non-anti-clip area: in the region, Anti-theft shutter 12 is met when rising
To barrier, (such as 20-150mm) stops after motor 5 can invert a distance, if the body for encountering object or person hinders
(anti-grip force is greater than 100N), motor 5 allows for detecting and inverting operation, to ensure to crush a part of human body such as
Hand, arm etc.；Self-shield effect is also functioned to simultaneously, and motor 5 will not be damaged because of overload；
Three, the acquisition of regional signal locating for the identification of anti-clip area and non-anti-clip area and automatically-controlled door: when motor 5 just starts, due to electricity
The counter electromotive force of machine 5 is established not yet, thus electric current has the higher magnitude of short time, and current amplitude at this moment is often than set
Fixed anti-pinch current threshold is also big, needs by the biggish state of this current amplitude and in 12 closing process of Anti-theft shutter
Obstacle produce are encountered to come；Motor 5 is delayed after 50 ms after starting, then carries out current detecting, avoids 5 initial start stage electric current of motor
The shadow noon that transient overshoot sets anti-pinch current threshold.
Small magnet block is fixed on the rotor 7 of motor 5, by TMR speed probe 8 near small magnet, when motor 5
After rotation, magnet can be primary close to TMR speed probe 8 within certain period, and such TMR speed probe 8 will output
One high level, when small magnet is far from TMR speed probe 8, TMR speed probe 8 exports a low level；Utilize monolithic
2 timer internal of machine calculates the time of pulse a cycle, detects the revolving speed of motor 5, mechanism anti-pinch design scheme uses will
TMR speed probe 8, TMR current sensor 6 detect 5 revolving speed of motor and detection 5 curent change situation of motor combines realization
Pinch resistant functionality, it is ensured that anti-pinch effect is reliable, and cost is relatively low；
Wherein, the signal of single-chip microcontroller 2 is AT89c51, model MMGB015, the TMR current sensor 6 of TMR speed probe 8
The equal TMR2703 of model, the model LZR-U9010 of infrared scan inductor 3, the model 110MB120C- of motor 5
501000。
Embodiment 2
Please refer to Fig. 1-5, be further improved on the basis of embodiment 1: anti-clipping system 1 is connected by conducting wire and external power supply
It connects, is that entire circuit connects electricity by external power supply, motor 5 is servo motor, TMR speed probe 8 and TMR current sensor 6
It is located at the two sides up and down of rotor 7, in this way revolving speed and electric current of the setting convenient for induction detection motor 5, TMR speed probe 8
The two sides up and down of rotor 7 are located at TMR current sensor 6, several infrared scan inductors 3 are apart from Anti-theft shutter 12
Front end face distance be 1.5cm, such purpose is in order to enable several infrared scan inductors 3 are during scanning
The influence of Anti-theft shutter 12 is not will receive, that is to say, that in anti-clip area, infrared scan inductor 3 is equipped with respective range
Scanning area does not scan in non-anti-clip area, does not influence Anti-theft shutter 12 in this way and fasten, once there is barrier to enter infrared sweep
When retouching the scanning induction range of inductor 3, then also mean that the body of customer is likely to be exposed on Anti-theft shutter 12,
Single-chip microcontroller 2 will be switched off relay 4 at this time, then motor 5 then stops operating, in order to avoid customer's body is caused to abrade, buffer board 14
