In the prior art, the warning device of existing multiple supervision, detection wheel air pressure, be called " tire pressure autoalarm " as name, the patent No. is the disclosed technical scheme of Chinese utility model patent of ZL02254489.5, one baroswitch is installed on the valve of tire, and baroswitch is linked to each other with projector by lead, and projector is installed on the tire, what cooperate with projector is a receptor, and receptor determines whether to report to the police according to data that receive and relevant being provided with.Another name is called " tire pressure detection alarm device ", the patent No. is the disclosed technical scheme of the utility model patent of ZL200320111224.7, warning device is made up of press detection sensor, transmission circuit and reception warning circuit, and press detection sensor and transmission circuit are assemblied in the tire air chamber.The deficiency of these two kinds of tire pneumatic pressure detectors mainly contains: 1, be installed on tire or the wheel hub owing to projector, tire is bigger to the decay of radiofrequency signal, like this signal that receives of receptor a little less than, receptor usually can not correctly receive the emission data, thereby makes receptor can receive the close together of the signal of projector emission exactly; 2, projector is not connected with tire tube valve, is not easy to the fixing of projector like this, for fixed launcher, also must adopt other method to solve the installation question of projector.
Summary of the invention
The utility model at the projector in the existing tire inflation pressure determining system through signal behind the tire a little less than, receptor correctly receives this nearer defective of signal distance of projector emission, and a kind of detection and feedway that utilizes tire tube valve as the tire pressure temperature of emitting antenna is provided.
The technical solution of the utility model: the detection of tire pressure temperature and feedway, comprise tire tube valve and tire pressure temperature detection and launch-box, its improvements are: described tire tube valve is provided with insulating barrier, the metal tube of described tire tube valve is electrically connected with described launch-box, utilizes tire tube valve as antenna;
Above-mentioned metal tube is electrically connected with the prevention at radio-frequency port of described detection and transmission circuit through connecting lead-in wire;
Mode for flexibly connecting between described tire tube valve and tire pressure temperature detection and the launch-box.
The detection and the feedway of the utility model tire pressure temperature, utilize tire tube valve to launch the pressure and temperature value of detected tire as emitting antenna, not only the signal that is sent is strong, anti-interference resistance is good, thereby the signal that receiver is received is strong, can judge the abnormal condition of tire pressure and temperature in time, exactly; Simple in structure, do not increase extra cost basically; Adapt to widely, can be applied to the vehicle that all adopt the radial vacuum tires.
Description of drawings
