Abstract
The utility model belongs to the field of tyre pressure detection devices and in particular relates to a tyre pressure sensor. The tyre pressure sensor comprises a sensor chip, wherein the sensor chip is mounted on a tyre valve; a microprocessor, a low-frequency receiver and a radio-frequency emitter are integrated on the sensor chip. According to the technical scheme of the utility model, the tyre pressure sensor can monitor parameters, such as tyre pressure and temperature, of the tyre in real time, can receive an external low-frequency magnetic field signal and can transmit a wireless high-frequency signal to transfer information to a controller, so that a driver can know information such as the tyre pressure and the tyre temperature of a vehicle in real time; the tyre pressure sensor can send out light ray or sound alarm prompt when the tyre is in a tytre punctured premonition states of air deficiency, air leakage or overhigh tyre temperature and the like, so that the driver can actively take preventive measures of deceleration, stopping, air supply and the like to avoid accidents.
Description
Technical field
The utility model belongs to the tire inflation pressure determining apparatus field, relates in particular a kind of tyre pressure sensor.
Technical background
Motor tire is the constituent elements that automobile is wanted most, it has vital effect for the safety traffic that ensures automobile, system for monitoring pressure in tyre (Tire Pressure Monitoring System, TPMS) be by adopting tire pressure sensing unit and the tire pressure monitoring unit of twireless radio-frequency communication, having realized the real-time monitoring to tire pressure.At present, the tyre pressure sensor used on market is because the rotation that is subject to tire and other parts stops, the signal received has very to the decay on degree, cause receptor to receive signal stable not, the accuracy of impact monitoring, can not implement instant alarming, the safety traffic of motor tire is existed to very large impact.
The utility model content
The technical problems to be solved in the utility model is to provide a kind of stronger tyre pressure sensor of signal that can realize transmission over radio and receive signal and transmission and reception.
For solving the problems of the technologies described above, the utility model provides a kind of tyre pressure sensor, comprises sensor chip, and sensor chip is arranged on tire valve, is integrated with microprocessor, low frequency receptor, radio frequency sending set on sensor core plain film.
Preferably, also be integrated with random number generator in sensor chip.
Preferably, also be integrated with battery in sensor chip.
Preferably, battery is lithium cell.
Preferably, the radio frequency output of radio frequency sending set is connected on tire valve.
Preferably, tire valve is metallic material.
Preferably, the sensor chip outer wrap has one deck epoxy resin.
Adopt the beneficial effect of technique scheme to be: to be arranged on the wheel hub of motor tire by the valve door by tyre pressure sensor, the tyre pressure sensor chip is placed in motor tire inside, carry out the information such as the air pressure of instant monitoring motor tire inside and temperature, and the information exchange that monitoring is collected is crossed radio frequency sending set and is outputed on the valve door, by valve goalkeeper signal, launch on controller because tyre pressure sensor can be along with tyre rotation, so tyre pressure sensor can not be used the power supply of automobile self, so self be integrated with battery in the tyre pressure sensor chip, for the work of this tyre pressure sensor improves electric energy, integrated random number generator on tyre pressure sensor, prevent a plurality of sensors data continuous collision interference during the radio frequency transmission data simultaneously, on tyre pressure sensor integrated microprocessor can self judgment work at present pattern and radio frequency send condition, the low frequency receptor, for triggering, test and change mode sensor, because inside tires is because the change of air pressure and temperature has produced smuggled goods steam, so parcel one deck epoxy resin on induction chip, played the effect of waterproof.
The accompanying drawing explanation
The structural representation that Fig. 1 is a kind of tyre pressure sensor of the utility model,
Wherein, 1, the cranked tire valve door, 2, microprocessor, 3, the low frequency receptor, 4, battery, 5, random number generator, 6, sensor chip, 7, radio frequency sending set, 8, epoxy resin.
The specific embodiment
Below in conjunction with Figure of description, the technical solution of the utility model and structure are described, so that those skilled in the art understand.
As shown in Figure 1, a kind of tyre pressure sensor, comprise sensor chip 6, sensor chip 6 is arranged on tire valve 1, be integrated with microprocessor 2, low frequency receptor 3, radio frequency sending set 7 on sensor core plain film 6, also be integrated with random number generator 5 in sensor chip 6, also be integrated with battery 4 in sensor chip 6, battery 4 is lithium cell, the radio frequency output of radio frequency sending set 7 is connected on tire valve 1, tire valve 1 is metallic material, and sensor chip 6 outer wrap have one deck epoxy resin 8.
Adopt the beneficial effect of technique scheme to be: to be arranged on the wheel hub of motor tire by the valve door by tyre pressure sensor, the tyre pressure sensor chip is placed in motor tire inside, carry out the information such as the air pressure of instant monitoring motor tire inside and temperature, and the information exchange that monitoring is collected is crossed radio frequency sending set and is outputed on the valve door, by valve goalkeeper signal, launch on controller because tyre pressure sensor can be along with tyre rotation, so tyre pressure sensor can not be used the power supply of automobile self, so self be integrated with battery in the tyre pressure sensor chip, for the work of this tyre pressure sensor improves electric energy, integrated random number generator on tyre pressure sensor, prevent a plurality of sensors data continuous collision interference during the radio frequency transmission data simultaneously, on tyre pressure sensor integrated microprocessor can self judgment work at present pattern and radio frequency send condition, the low frequency receptor, for triggering, test and change mode sensor, because inside tires is because the change of air pressure and temperature has produced smuggled goods steam, so parcel one deck epoxy resin on induction chip, played the effect of waterproof.
Adopt a kind of tyre pressure sensor of technical solutions of the utility model, tire pressure in real-time monitoring tyres, the parameters such as temperature, and receive the external low frequency field signal, can send the wireless high-frequency signal information is passed to controller, relative barometric pressure value in tyre pressure sensor measured automobiles tire, gas temperature value in the measured automobiles tire, centripetal acceleration when testing automobile rotates, make the understanding vehicle tire air pressure that navigating mate can be real-time, the information such as temperature, and at tire, deficency appears, gas leakage or tire temperature are excessively high blows out during the omen state, emit beam or the audible alarm prompting, make navigating mate initiatively take in advance to slow down, stop, the preventive such as tonifying Qi avoid accident to occur.
Above-mentionedly by reference to the accompanying drawings utility model is exemplarily described; obviously the utility model specific implementation is not subject to the restrictions described above; as long as this non-essential improvement that has adopted method design of the present utility model and technical scheme to carry out; or without improving, the design of utility model and technical scheme are directly applied to other occasions, all within protection domain of the present utility model.
