Device start-up microwave transmit with passive card

Abstract

The present invention relates to a device which uses a passive power card to start-up a microwave transmitting, and comprises a SCM, a power supply module, a card-reading module of the passive power card, a watchdog, a memorizer module and a microwave transmitting module, wherein the SCM is respectively connected with the power supply module, the card-reading module of the passive power card, the microwave transmitting module, the watchdog and the memorizer module. The power supply module supplies power for the SCM, the card-reading module of the passive power card, the watchdog, the memorizer module and the microwave transmitting module. The controlling method of the device is that the SCM reads the card number in a radio frequency card and judges whether the information in the card is valid. If the information is valid, the microwave transmitting module is provided with power, otherwise, the microwave transmitting module is not provided with power. After the microwave transmitting module is provided with power, the unique microwave identity identifying code which is solidified is transmitted by the microwave transmitting module. The present invention has the advantages that the vehicle identification can obtain twice affirmance by using the radio frequency, the phenomenon of vehicle losing caused by the false identification of a random card is avoid. At the same time, the energy conservation and the environmental protection are realized, and a universal card can be used in the distribution park management.

Description

Technical field [0001] The invention relates to the technical field of vehicle identification, in particular to a device that uses a passive card to start microwave transmission. Background technique [0002] With the improvement of living standards, all kinds of vehicles in our country have been greatly popularized, and automobiles have penetrated into all aspects of people's lives. However, the management of vehicles in the park has a low degree of intelligence and is still in its infancy. At present, in the park, most of the management of vehicles uses passive cards or active cards for identification. Various vehicles are often misidentified. When the weather is bad, reliable identification cannot be guaranteed. Therefore, the safety in the park is poor and easy There is a phenomenon of vehicle loss. Among them, the active card recognition consumes a lot of power, causing users to use trouble and environmental pollution. Summary of the invention [0003] Aiming at the deficie...

[0002] With the improvement of living standards, all kinds of vehicles in our country have been greatly popularized at present, and cars have penetrated into all aspects of people's lives, but the intelligent management of vehicles in the park is still in its infancy.

At present, in the park, the management of vehicles mostly uses passive cards or active cards for identification. Misidentification of various vehicles often occurs, and reliable identification cannot be guaranteed when the weather is bad. Therefore, the security in the park is poor and easy The phenomenon of vehicle loss

Among them, active card identification consumes a lot of power, causing troubles for users and environmental pollution
