Abstract
The invention discloses an intelligent automobile tire pressure early warning system. The intelligent automobile tire pressure early warning system comprises a tire pressure sensor for testing pressure of each tire, a noise detector for testing noises generated when an automobile is started, a signal transmitting device which is connected with the tire pressure sensor and the noise detector respectively, and a signal receiving device, a control device and a display device which are located in a seat cabin; the signal transmitting device is used for transmitting signals sent by the tire pressure sensor and the noise detector to the signal receiving device; the signal receiving device is used for transmitting the signals to the control device; the control device comprises a TPMS (Tire Pressure Monitor System) main engine and a judging circuit; the TPMS main engine is used for converting the signals into digital signals; and the digital signals are judged by the judging circuit and corresponding signals are output to the display device. The intelligent automobile tire pressure early warning system, tire pressure signals are received and noise signals obtained by testing the sensitive degree to angular displacement by a tire; and the signals are automatically fed back into the control device in the seat cabin, and are automatically judged and displayed by the control device, and the intelligent degree is high.
Description
Technical field
The present invention relates to a kind of vehicle tire pressure intelligent early-warning system.
Background technology
The safe driving of pressure to automobile of motor tire is extremely important, easily threatens to safe driving if tire pressure is unstable or temperature is too high.Tire pressure method for early warning requires to realize carrying out detection alarm to tire flat and infrabar, thus guarantees the safety of driving.The system designing a kind of intelligent early-warning vehicle tire pressure situation is extremely important.
Summary of the invention
The object of this invention is to provide a kind of vehicle tire pressure intelligent early-warning system.
To achieve these goals, the technical solution of employing is in the present invention:
A kind of vehicle tire pressure intelligent early-warning system, comprise the Creak detector of noise be located at tyre pressure sensor, the testing vehicle of testing each tire pressure and produced when starting, the sender unit be connected with tyre pressure sensor and Creak detector respectively, and the signal receiving device, control setup, the read out instrument that are positioned at passenger cabin; The signal that tyre pressure sensor and Creak detector send is sent to signal receiving device by described sender unit, and signal is sent to control setup by signal receiving device; Described control setup comprises TPMS main frame, decision circuitry, and signal is converted into digital signal by TPMS main frame, and digital signal judges through decision circuitry, exports corresponding signal to read out instrument.
In advance tire magnitude of voltage, noise figure being divided into several threshold ranges is respectively kept in decision circuitry, and when the digital signal that decision circuitry receives is in respective range, control setup drives read out instrument open and show corresponding information.
Also be provided with warning phonation unit, when tire magnitude of voltage or noise figure exceed the threshold value of safe range, start warning phonation unit.
Beneficial effect of the present invention: the noise signal that the sensitivity that the present invention receives tire pressure signal and testing tire diagonal displacement obtains, is automatically fed in the control setup in passenger cabin, and automatically judged to show by control setup, intelligence degree is high.
Detailed description of the invention
A kind of vehicle tire pressure intelligent early-warning system, comprise the Creak detector of noise be located at tyre pressure sensor, the testing vehicle of testing each tire pressure and produced when starting, the sender unit be connected with tyre pressure sensor and Creak detector respectively, and the signal receiving device, control setup, the read out instrument that are positioned at passenger cabin; The signal that tyre pressure sensor and Creak detector send is sent to signal receiving device by described sender unit, and signal is sent to control setup by signal receiving device; Described control setup comprises TPMS main frame, decision circuitry, and signal is converted into digital signal by TPMS main frame, and digital signal judges through decision circuitry, exports corresponding signal to read out instrument.
In advance tire magnitude of voltage, noise figure being divided into several threshold ranges is respectively kept in decision circuitry, and when the digital signal that decision circuitry receives is in respective range, control setup drives read out instrument open and show corresponding information.Threshold range determines according to pressure of tire and vehicle performance determines.In the present embodiment, multiple threshold range comprises: (1) is greater than normal data more than 10%, (2) be greater than normal data less than 10% to being greater than normal data more than 5%, (3) be greater than that less than 5% of normal data is less than normal data less than 5%, (4) be less than normal data more than 5% to being less than normal data less than 10%, (5) are less than normal data more than 10%.When during (1) (2) (4) (5) situation, tire pressure condition being shown by read out instrument more than occurring.
Also be provided with warning phonation unit, when tire magnitude of voltage or noise figure exceed the threshold value of safe range, and belong to (1) (5) and start warning phonation unit prompting driver parking checking when planting situation and remove a hidden danger.
Certainly, above-mentioned explanation is not limitation of the present invention, and the present invention is also not limited in above-mentioned citing, and the change that those skilled in the art make in essential scope of the present invention, remodeling, interpolation or replacement also should belong to protection scope of the present invention.
