Abstract
The utility model relates to a wireless monitoring and automatic control device for tire pressure, which is provided with a control host. The control host is provided with a receiving antenna, a pressure measuring auxiliary machine is arranged near a tire valve, and the control host controls an air supply by an electromagnetic valve. The utility model has the advantages that a wireless technology is adopted to reduce body wiring, the tire pressure is detected in time, and a pressure value is wirelessly sent to the control host in a cab. A driver sets current road conditions and vehicle load conditions according to actual situation, and the control host judges whether the tire pressure is normal or not according to the set road conditions and load conditions. If the tire pressure is lower than a standard value, a tire is automatically inflated. If the tire pressure is higher than the standard value, the tire is deflated. The tire pressure can be automatically adjusted according to the road conditions and load conditions, and the whole process can be carried out without parking, so the safety and the mobility of vehicles can be enhanced.
Description
Affiliated technical field
The utility model relates to the speciality car safety device, relates in particular to automobile is not stopped in the way of advancing and can and charge and discharge the controlled atmosphere joint automatically to the tire pressure wireless monitor.
Background technology
Existing vehicle tyre checking system just detects advance notice to vehicle tyre pressure, and road pavement, load etc. are effect not, therefore is not suitable for heavy special vehiclees such as battlebus.Also can only detect simultaneously, can't regulate unsuitable pressure.
Summary of the invention
The purpose of this utility model provides the tire pressure wireless monitor of a kind of safety that can strengthen vehicle and manoevreability and automatic control device to remedy the deficiency of prior art.
The utility model for realizing the technical scheme that purpose adopts is: a kind of tire pressure wireless monitor and automatic control device is characterized in that: be provided with the secondary machine of main control system and pressure measurement; Receiving wire is arranged on the main frame, be used to receive the signal of the secondary machine of pressure measurement; Main control system is by solenoid control source of the gas break-make.
The beneficial effects of the utility model: adopt wireless technology to reduce the vehicle body wiring, detection wheel tire pressure in good time is wirelessly transmitted to force value the main control system of operator's compartment.Navigating mate is provided with current road conditions and car load situation according to actual conditions.Main control system judges according to the road conditions and the load condition that are provided with whether tire pressure is normal.If tire pressure is lower than standard value then automatically tire is put on the air, if tire pressure is higher than standard value to bleeding a tire.To the tire pressure automatically regulating, whole process dispense with parking can be strengthened the safety and the manoevreability of vehicle according to road conditions and load condition.
Below in conjunction with accompanying drawing, the utility model is further described by embodiment:
Description of drawings
Fig. 1 is the structural representation that the utility model is implemented.
A kind of tire pressure wireless monitor and automatic control device are provided with main control system 3 at operator's compartment, and receiving wire 4 is arranged on the main control system 3; Being provided with the secondary machine 11,5,6,7,8,9,10 of pressure measurement near tire valve is six tires, air pump 1 be vehicle itself from carrying device, the pressure of 0.8MPa can be provided for this device; Solenoid valve box 2 is fabricate blocks of 12 electromagnetic valves, and each tire all has a corresponding inflation electromagnetic valve and a pressure-releasing electromagnetic valve, and main control system 3 is positioned at operator's compartment, is the parts that show and operate.
The specific embodiment
Embodiment 1:
Taking turns battlebus with six is example, supposes that the present deadhead operation of vehicle is on the expressway.Chaufeur is provided with the road surface and is " at a high speed " on main control system 3, load is " zero load ", and the tire pressure scope that this device will settle the standard according to " at a high speed " and " zero load " these two conditions this moment is 0.48---0.5MPa.The pressure of the secondary machine 11 periodic monitor tires of pressure measurement, and the radio signal of force value with 433MHz sent out is by receiving wire 4 acceptance and pass to main control system 3, if the force value that monitors is 0.45MPa.Obviously this moment, tire pressure was lower than standard value.The inflation electromagnetic valves that main control system 3 just drives in the solenoid valve box 2 are opened, air pump 1 and tire 5---10 connect, to inflation of tire, up to the pressure that monitors to reaching 0.48---0.5MPa.Inflation closed electromagnetic valve in the clack box 2 stops inflation.
And when car two is sailed down the expressway to cross-country highway.Chaufeur is provided with the road surface and is " cross-country ".The range of pressure that this moment, this device settled the standard is 0.44---0.46MPa.Obviously, the pressure in tire this moment has been higher than standard value.Main control system is opened by the pressure-releasing electromagnetic valve in the clack box with regard to sending electric signal, and tire is outwards exitted.When monitoring pressure 0.44---in the time of in the 0.46MPa scope, main control system control pressure-releasing electromagnetic valve is closed, and stops venting.
Whole device can be divided into three parts.Receiving wire 4 is car gage antennas.Main control system 3 is centers of device.CPU lpc2220 is operated on the uc/OS II operating system, accepts the pressure signal that antenna 4 transmits, and it is presented on the LCDs, simultaneously also control electromagnetic valve case 2 work.
Another part of device is the secondary machine 11 of pressure measurement, utilizes nRF905 that pressure data is sent out by CPU mega8 behind the pressure sensor MPXY8040 monitoring pressure of the secondary machine 11 employing Freescales of pressure measurement.
