Description
Technical field
The present invention relates to a kind of vehicle safety safeguards technique, specifically a kind of displacement magnetic coupling type tire pneumatic pressure detector.
Background technology
In vehicle travel process, tire pressure too low or cross big city affect vehicle safety, it is very necessary for therefore developing a kind of tire pressure Real-time and On-line.Existing tyre pressure detecting system adopts wireless receiving and dispatching formula or electromagnetic type.Its shortcoming is that circuit structure is complicated, and battery often will be changed.
Summary of the invention
The object of the present invention is to provide a kind of displacement magnetic coupling type tire pneumatic pressure detector, employing mutual inductor, expanded film carry out a kind of tire pneumatic pressure detector detected.This tire pneumatic pressure detector is without the need to installing power supply at wheel tyre cavity, and circuit is simple, easy for installation.
The present invention includes expanded film, output primary, first secondary coil and alternating current sample circuit, the technical scheme adopted is: expanded film and gas circuit are fixedly connected, expanded film and connecting rod are fixedly connected, connecting rod and output primary are fixedly connected, first secondary coil is connected with signal conditioning circuit by alternating current sample circuit, signal conditioning circuit is connected with system, control circuit by comparator circuit, and system, control circuit is also connected with warning circuit.
The present invention is by adopting mutual inductor, expanded film, and solve needs of the prior art and install battery problems at tire, circuit is simple.
Accompanying drawing explanation
Below in conjunction with drawings and Examples, the present invention is described in further detail.
Fig. 1 is structural representation of the present invention.
In Fig. 1: 1. expanded film, 2. output primary, 3. first secondary coil, 4. alternating current sample circuit, 5. comparator circuit, 6. system, control circuit, 7. warning circuit, 8. signal conditioning circuit, 9. connecting rod, 10. gas circuit.
Detailed description of the invention
Shown in Fig. 1: expanded film 1 and gas circuit 10 are fixedly connected, expanded film 1 and connecting rod 9 are fixedly connected, connecting rod 9 and output primary 2 are fixedly connected, first secondary coil 3 is connected with signal conditioning circuit 8 by alternating current sample circuit 4, signal conditioning circuit 8 is connected with system, control circuit 6 by comparator circuit 5, and system, control circuit 6 is also connected with warning circuit 7.
Principle of work of the present invention is as follows: output primary 2 is closing coils.When tire pressure is in standard pressure, output primary 2 passes through the expansion of expanded film 1 just in time an appropriate position, output primary 2 and first secondary coil 3 carry out magnetic coupling, electric current in first secondary coil 3 is sampled by alternating current sample circuit 4, this sampled signal compares after signal conditioning circuit 8 is nursed one's health in comparator circuit 5, export a signal more afterwards to system, control circuit 6, system, control circuit 6 sends to warning circuit 7 forbids alerting signal, and vehicle normally continues to travel.
If in the process of moving, tire pressure is excessive, by the expansion of expanded film 1, connecting rod 9 drives output primary 2 to move right, first secondary coil 3 is strengthened with output primary 2 magnetic coupling, ER effect in first secondary coil 3 is large, electric current in first secondary coil 3 is sampled by alternating current sample circuit 4, this sampled signal compares after signal conditioning circuit 8 is nursed one's health in comparator circuit 5, export a signal more afterwards to system, control circuit 6, send one by system, control circuit 6 to warning circuit 7 and start alerting signal, warning circuit 7 is reported to the police.
If in the process of moving, tire pressure is too low, by the contraction of expanded film 1, connecting rod 9 drives output primary 2 to be moved to the left, first secondary coil 3 weakens with output primary 2 magnetic coupling, electric current in first secondary coil 3 diminishes, electric current in first secondary coil 3 is sampled by alternating current sample circuit 4, this sampled signal compares after signal conditioning circuit 8 is nursed one's health in comparator circuit 5, export a signal more afterwards to system, control circuit 6, send one by system, control circuit 6 to warning circuit 7 and start alerting signal, warning circuit 7 is reported to the police.
Like this, adopt expanded film 1 and alternating current sample circuit 4, utilize the magnetic coupling of mutual inductor, achieve the on-line real-time measuremen of tire pressure.
