Description
Technical field
The present invention relates to a kind of vehicle safety safeguards technique, specifically a kind of tire pneumatic pressure detector based on wireless charging technology.
Background technology
In vehicle travel process, tire pressure is too low or crosses metropolis' impact vehicle safety, and it is very necessary for therefore developing a kind of tire pressure on-line real-time measuremen device.Existing tire pneumatic pressure detector adopts wireless receiving and dispatching formula or electromagnetic type.Its shortcoming is that circuit structure is complicated, and battery often will be changed.
Content of the invention
It is an object of the invention to provide a kind of tire pneumatic pressure detector based on wireless charging technology, a kind of tire pneumatic pressure detector being detected using electric energy transmitting circuit, electric energy receiving circuit and pressure transducer.This tire pneumatic pressure detector need not install power supply in wheel tyre cavity, and circuit is simple, easy for installation.
The present invention includes electric energy transmitting circuit, electric energy receiving circuit and pressure transducer, and the technical scheme being adopted is：Pressure transducer is connected with cpu circuit, cpu circuit is connected with signal transmitting antenna by signal transmission circuit, electric energy receiving coil is connected with cpu circuit by electric energy receiving circuit, signal receiving antenna is connected with system, control circuit by signal receiving circuit, system, control circuit is connected with electric energy transmitting coil by electric energy transmitting circuit, and system, control circuit is also connected with warning circuit.
The present invention passes through using electric energy transmitting circuit, electric energy receiving circuit and pressure transducer, solves needs of the prior art and installs battery problems in tire, circuit is simple.
Brief description
With reference to the accompanying drawings and examples the present invention is described in further detail.
Fig. 1 is the structural representation of the present invention.
In Fig. 1：1. pressure transducer, 2.CPU circuit, 3. signal transmission circuit, 4. signal transmitting antenna, 5. signal receiving antenna, 6. signal receiving circuit, 7. warning circuit, 8. system, control circuit, 9. electric energy transmitting circuit, 10. electric energy transmitting coil, 11. electric energy receiving coils, 12. electric energy receiving circuits.
Specific embodiment
Shown in Fig. 1：Pressure transducer 1 is connected with cpu circuit 2, cpu circuit 2 is connected with signal transmitting antenna 4 by signal transmission circuit 3, electric energy receiving coil 11 is connected with cpu circuit 2 by electric energy receiving circuit 12, signal receiving antenna 5 is connected with system, control circuit 8 by signal receiving circuit 6, system, control circuit 8 is connected with electric energy transmitting coil 10 by electric energy transmitting circuit 9, and system, control circuit 8 is also connected with warning circuit 7.
The operation principle of the present invention is as follows：System, control circuit 8 controls electric energy transmitting circuit 9 to deliver the power to electric energy receiving circuit 12 by electric energy transmitting coil 10 and electric energy receiving coil 11, electric energy receiving circuit 12 arranges to received electric energy as appropriate voltage, uses for cpu circuit 2 and signal transmission circuit 3.
When tire pressure is in normal pressure, signal on pressure transducer 1 is after cpu circuit 2 collection calculates and signal transmission circuit 3 is modulated, launched by signal transmitting antenna 4, after signal receiving antenna 5 receives this signal, calculate through signal receiving circuit 6 demodulation system, control circuit 8 and judge.Due to now signal amplitude, within prescribed limit, system, control circuit 8 does not start warning circuit 7, and warning circuit 7 is not reported to the police, and vehicle normally continues to travel.
If in the process of moving, tire pressure is excessive, and the signal on pressure transducer 1, after cpu circuit 2 collection calculates and signal transmission circuit 3 is modulated, is launched by signal transmitting antenna 4, after signal receiving antenna 5 receives this signal, calculate through signal receiving circuit 6 demodulation system, control circuit 8 and judge.Because now signal amplitude is on prescribed limit, system, control circuit 8 starts warning circuit 7, and warning circuit 7 is reported to the police.
If in the process of moving, tire pressure is too small, and the signal on pressure transducer 1, after cpu circuit 2 collection calculates and signal transmission circuit 3 is modulated, is launched by signal transmitting antenna 4, after signal receiving antenna 5 receives this signal, calculate through signal receiving circuit 6 demodulation system, control circuit 8 and judge.Because now signal amplitude is under prescribed limit, system, control circuit 8 starts warning circuit 7, and warning circuit 7 is reported to the police.
So, using electric energy transmitting circuit 9, electric energy receiving circuit 12 and pressure transducer 1 it is achieved that the on-line real-time measuremen of tire pressure.
