Description
Technical field
The utility model relates to a kind of foot-operated sensor.
Background technology
At present, the field of examining is driven in intelligence, driving and examining what automobile is used for pair stops is a kind of stretcher, respond on this stretcher whether have footbrake action by the infrared facility be fixed on brake pedal plate anchor shaft, namely, when the people of copilot station is put pin on the footrests, the infrared facility be fixed on brake pedal plate anchor shaft just can sense foot-operated action.
But easily there is cheating in this device gathering brake in examination process, when the people of copilot station taps below this stretcher with tiptoe, also intentional brake operation can be carried out, but the infrared facility that the position stepped on can not be fixed on brake pedal plate anchor shaft senses, just cause examination student achievement higher or lower than normal level phenomenon.
Utility model content
For the weak point existed in the problems referred to above, the utility model provides a kind of foot-operated sensor.
For achieving the above object, the utility model provides a kind of foot-operated sensor, comprising:
Foot-operated sensor housing, is provided with circuit card and sensor in described foot-operated sensor housing inside;
Described circuit card is provided with amplifying circuit, wireless CPU, antenna and power input;
Described power input and described amplifying circuit are connected with described sensor respectively;
Described wireless CPU is connected with described antenna.
Preferred as the utility model, described sensor is semibridge system LOAD CELLS.
Preferred as the utility model, described foot-operated sensor housing comprises upper casing and lower casing, and described upper casing and described lower casing are screwed.
Preferred as the utility model, described upper casing upper surface is suppressed with multiple anti-skidding projection.
Preferred as the utility model, described lower casing lower surface is suppressed with multiple fixed lobe.
Preferred as the utility model, described fixed lobe is T-shaped.
The beneficial effects of the utility model are: have foot-operated action just can sense and brake above stretcher, as long as there is foot-operated action, server end just can obtain the size of the power ridden, substantially increase and drive the secondary accuracy rate and fairness of passing judgment on item of stopping in examination process, the plurality of advantages such as structure is simple, convenient to use.

In figure: 1, foot-operated sensor housing; 2, circuit card; 3, power input; 4, sensor; 5, amplifying circuit; 6, wireless CPU; 7, antenna; 8, upper casing; 9, anti-skidding projection; 10, lower casing; 11, fixed lobe.
Detailed description of the invention
As shown in Figure 1, the one described in the utility model embodiment rides sensor, comprising: foot-operated sensor housing 1, is provided with circuit card 2 and sensor 4 in described foot-operated sensor housing 1 inside; Described circuit card 2 is provided with amplifying circuit 5, wireless CPU 6, antenna 7 and power input 3; Described power input 3 and described amplifying circuit 5 are connected with described sensor 4 respectively; Described wireless CPU 6 is connected with described antenna 7.Described sensor 4 is semibridge system LOAD CELLS.Be built-in with the stretcher of semibridge system LOAD CELLS circuit card, when pin is trampled above this stretcher, semibridge system LOAD CELLS just senses trample action by strain-gauge and deformation occurs, thus cause resistance sizes to change, thus cause voltage to change, the variable quantity of voltage is collected by wireless singlechip NRF24LE1-2.4G AD after amplifier is amplified, and output to capture card, simultaneously, server just detects the size of the power stepped on the footrests in real time by wireless communication mode by the built-in aerial on circuit card, can judge whether pair position of stopping has brake.
There is foot-operated action just can sense and brake above stretcher, as long as there is foot-operated action, server end just can obtain the size of the power ridden, and substantially increases and drives the secondary accuracy rate and fairness of passing judgment on item of stopping in examination process, the plurality of advantages such as structure is simple, convenient to use.
As shown in Figure 2, described foot-operated sensor housing 1 comprises upper casing 8 and lower casing 10, and described upper casing 8 is screwed with described lower casing 10, and described upper casing 8 upper surface is suppressed with multiple anti-skidding protruding 9.Anti-skidding projection is evenly distributed, prevents from riding skidding above.
As shown in Figure 3, described lower casing 10 lower surface is suppressed with multiple fixed lobe 11, and described fixed lobe 11 is T-shaped, and its fixed effect is better.
During concrete use: comprise foot-operated sensor housing 1, circuit card 2 and semibridge system LOAD CELLS 4, it is inner that circuit card 2 and semibridge system LOAD CELLS 4 are arranged on foot-operated sensor housing 1, power panel 2 comprises power input 3, amplifying circuit, wireless CPU 6 and antenna 7, wherein, power input 3 is connected with semibridge system LOAD CELLS 4, semibridge system LOAD CELLS 4 is connected with amplifying circuit 5, and amplifying circuit 5 is connected with wireless CPU 6, and wireless CPU 6 is connected with antenna.Semibridge system LOAD CELLS 4 can bear the power of 50KG, and when acting on effectively, the strain-gauge in semibridge system LOAD CELLS 4 deformation will occur, thus causes semibridge system LOAD CELLS 4 resistance to change.The change of semibridge system LOAD CELLS 4 resistance, causes voltage to change, and through the amplification of amplifying circuit, is input to wireless CPU 6 and carries out AD collection, and export.Meanwhile, wireless CPU carries out wireless telecommunications by antenna and server end, the size of power can be detected in real time.
The foregoing is only preferred embodiment of the present utility model, be not limited to the utility model, for a person skilled in the art, the utility model can have various modifications and variations.All within spirit of the present utility model and principle, any amendment done, equivalent replacement, improvement etc., all should be included within protection domain of the present utility model.
