Abstract
A kind of novel electromagnetic tire inflation pressure determining system, comprises magnet coil, pull back spring, permanent magnet, AD conversion module, MCU, alarm display module composition.Pull back spring directly and wheel rim be fixedly connected, and communicate with automotive tire pressure, when inner tyre pressure changes, gas push pull back spring in tire moves around, induction coil is made to induce different electric current wire sizes, by the current signal of change by A D conversion module analog signal changed into current signal pass to micro controller system, micro controller system is presented on attention display by the pressure of analyzing and processing by tire.
Description
Technical field
The utility model relates to a kind of novel electromagnetic tire inflation pressure determining system, belongs to field of automobile safety.
Background technology
Along with auto trade develop rapidly, arteries of communication problem is faced with huge challenge.In vehicle traveling process, tire too expands or is in underinflation state all can affect vehicle safety, how carries out Clinical significance of detecting to tire pressure in automotive operation great.Vehicle tire pressure detection system is for real-time, automatic monitoring measuring wheel air pressure in vehicle traveling process.Tire flat and infrabar are reported to the police, with a kind of systems technology of guarantee driving safety.
Summary of the invention
The purpose of this utility model is to solve the problem, and provides a kind of novel electromagnetic tire pressure monitoring method.Be achieved through the following technical solutions:
A kind of novel electromagnetic pressure detecting system, comprise pull back spring, permanent magnet, magnet coil, AD conversion module, MCU and warning, the direct wheel rim of described pull back spring is fixedly connected, and communicate with automotive tire pressure, the change of inner tyre pressure promotes pull back spring and moves around thus cause induction coil to induce different current signals.Induction coil and A D conversion module be connected, A D conversion module be connected with micro controller system, meanwhile, micro controller system is connected with alarm display module.
The utility model compares the advantage of prior art:
1. the utility model is simple and practical, Stability Analysis of Structures, has longer work life, good operating stability than traditional mechanical tire pressure sensor.
2. take off data is accurate, convenient signal treatment process is convenient, because directly driven the change of sensor voltage signal and current signal by the change of tire pressure, the signal of change is directly passed to micro controller system directly to be carried out calculating tire pressure value accurately by micro controller system.
3. the corresponding time is short, highly sensitive, and antijamming capability is strong, little at the annoyance level of running car when different road conditions for test result.
4. the mechanical type tire pressure sensor cost compared with traditional is low, and price is more cheap, reduces cost.
Accompanying drawing explanation
Fig. 1 is electromagnetic type tire inflation pressure determining system schematic diagram described in the utility model.
Detailed description of the invention
1-magnet coil; 2-wheel rim; 3-tire tube valve; 4-pull back spring; 5-permanent magnet;
6-AD modular converter; 7-MCU; 8-alarm display module.
Below in conjunction with embodiment accompanying drawing, the utility model is described further.
As shown in Figure 1, the utility model is a kind of novel electromagnetic tire inflation pressure determining system, comprises magnet coil 1, pull back spring 4, permanent magnet 5, AD conversion module 6, MCU7, alarm display system 8 form.Pull back spring 4 directly and wheel rim 2 be fixedly connected, and communicate with automotive tire pressure, when inner tyre pressure changes, gas push pull back spring 4 in tire moves around, induction coil is made to induce different electric current wire sizes, by the current signal of change by A D conversion module 6 analog signal changed into current signal pass to micro controller system 7, the pressure of tire is presented on attention display 8 by analyzing and processing by micro controller system, alerting signal will be sent when the pressure of tire is greater than some predetermined values time, prompting driver notes driving, and maintenance and inspection.
Claims (2)
