Description
Technical field
The utility model relates to a kind of device that can monitor safety status of tire in vehicle traveling process automatically, belongs to monitoring technical field.
Background technology
Tire explosion in the vehicle ' process is the one of the main reasons of bringing out traffic accident.Statistics shows that in the annual traffic accident, the accident that causes because of tire fault accounts for more than 70%, and wherein tyre break accident has accounted for 80% of tire accident total amount.Therefore, the vehicle tyre situation is monitored in real time,,, reduce traffic accident and have crucial meaning prevention tyre break so that in time change dangerous tire.
But present tyre break instrument provides warning in the time of can't being in criticality to tire, and the dangerous situation of Yin Faing is failed to report the safety that is seriously threatening driver and conductor and vehicle thus; And the implication of display data representative is not directly perceived, and the user is difficult for being directly acquainted with tire current safety situation.
The utility model content
The purpose of this utility model is to overcome the deficiencies in the prior art, a kind of vehicle tyre safety monitoring device that can monitor in real time tire in vehicle traveling process is provided.
Problem described in the utility model realizes with following technical proposals:
A kind of vehicle tyre safety monitoring device, be made up of main frame and extension set, it is indoor that described main frame is installed on vehicle drive, and described extension set is provided with a plurality of, be installed on respectively in each tire of automobile, communicate contact by radio-frequency transmissions circuit and radio-frequency (RF) receiving circuit between each extension set and the main frame;
Described main frame is made up of host-processor, radio-frequency (RF) receiving circuit, keyboard, telltale and warning circuit, wherein, be provided with radio frequency receiver in the radio-frequency (RF) receiving circuit, radio frequency receiver connects the P5.0～P5.3 end of host-processor, described keyboard connects the PORT3 interface of host-processor, described telltale connects the PORT2 interface of host-processor, and described warning circuit is made up of five LED alarm lamps, and they connect the P1.0～P1.4 end of host-processor respectively through bus transceiver.
Above-mentioned vehicle tyre safety monitoring device, described extension set is made up of extension set treater, tire parameter sensor and radio-frequency transmissions circuit, the P0.0 of described tire parameter sensor extension treater～P0.3 end, in the described radio-frequency transmissions circuit radiofrequency launcher is set, P1.0, the P1.1 end of described radiofrequency launcher extension treater.
The utility model utilizes the tire parameter sensor in each extension set to gather tire pressure in real time, temperature signal, and this signal delivered to the extension set treater, extension set treater may command radiofrequency launcher is with tire pressure, temperature signal and epicycle casing part identifying information pass to main frame with the wireless signal form, radio frequency receiver in the main frame is used to receive the signal from each extension set, host-processor is analyzed the signal from each extension set, judge whether tire exists the dangerous and concrete hazard level (also can finish) of explosion in extension set, and the control warning circuit sends early warning signal.Keyboard is used for the input operation order, and telltale is used to show details.The utility model can be monitored in real time to the safety case of motor tire, makes chaufeur in time change dangerous tire, stops the generation of tyre break phenomenon, greatly reduces traffic accident rate.
Description of drawings
The utility model is described in further detail below in conjunction with accompanying drawing.
Fig. 1 is an electric functional block diagram of the present utility model;
Fig. 2 is the electrical schematic diagram of main frame;
Fig. 3 is the electrical schematic diagram of extension set.
Each label is among the figure: MCU1, host-processor; MCU2, extension set treater; U1, radio frequency receiver; U2, bus transceiver; U3, tire parameter sensor; U4, radiofrequency launcher; LED1～LED5, alarm lamp; LCD, telltale; KB, keyboard.
The specific embodiment
Extension set of the present utility model is gathered supplemental characteristics such as the gentle tire pressure of tire in real time, MCU2 carries out intellectual analysis, processing to these data by the extension set treater, and the judgement signal (also can finish by host-processor MCU1) of reasoning output tyre break probability, by radiofrequency launcher U4 tire pressure, tire temperature, the two rate of change, explosion probability and the tire identity identification information (position of foetus ID sign indicating number) of tire sent to main frame at last.Main frame carries out verification, parsing to signal, calculates the tire risk grade, when the dangerous situation grade is higher, and corresponding alarm lamp high frequency flicker warn (still warning simultaneously) with buzzer phone; All the other parameters all show in real time by liquid crystal display.
Referring to Fig. 2, for improving the Scalable Performance of system, host-processor MCU1 adopts the microprocessor of 16 bit MSP430 of TI company, is provided with radio frequency receiver in the radio-frequency transmissions circuit, is provided with radio frequency receiver in the radio-frequency (RF) receiving circuit.Radio frequency receiver U1 adopts TDA5210.
