Description
Technical field
The present invention relates to a kind of vehicle safety safeguards technique, a kind of tire pneumatic pressure detector based on RF IC card technology specifically。
Background technology
In vehicle travel process, tire pressure too low or cross metropolis affect vehicle safety, it is very necessary for therefore developing a kind of tire pressure on-line real-time measuremen device。Existing tire pneumatic pressure detector adopts wireless receiving and dispatching formula or electromagnetic type。Its shortcoming is that circuit structure is complicated, and battery often to be changed。
Summary of the invention
It is an object of the invention to provide a kind of tire pneumatic pressure detector based on RF IC card technology, adopt RF IC card circuit, card reading circuit and press button to carry out a kind of tire pneumatic pressure detector detected。This tire pneumatic pressure detector is without installing power supply at wheel tyre cavity, and circuit is simple, easy for installation。
The present invention includes RF IC card circuit, card reading circuit and press button, the technical scheme adopted is in that: the upper static contact of press button is connected with RF IC card circuit by wire with lower stationary contact, RF IC card circuit is connected with RF IC card antenna, card reading antennas is connected with system, control circuit by card reading circuit, and system, control circuit is also connected with warning circuit。Press button is arranged between automotive hub and interior tire, and RF IC card antenna is arranged on the lower end of axletree, and card reading antennas is arranged in brake hubs, and corresponding with the position of the RF IC card antenna on axletree, and wire is inlayed and is arranged in axletree。
The present invention, by adopting RF IC card circuit, card reading circuit and press button, solves needs of the prior art and installs battery problems at tire, and circuit is simple。
Accompanying drawing explanation
Below in conjunction with drawings and Examples, the present invention is described in further detail。
Fig. 1 is the structural representation of the present invention。
Fig. 2 is the car wheel structure cut-away view of the present invention。
In figure: 1. upper static contact, 2. descend static contact, 3. wire, 4. RF IC card circuit, 5. RF IC card antenna, 6. card reading antennas, 7. card reading circuit, 8. warning circuit, 9. system, control circuit, 10. spring, 11. connecting rod, 12. movable contacts, 13. press buttones, 14. automotive hubs, 15. axletrees。
Detailed description of the invention
Shown in Fig. 1: the upper static contact 1 of press button 13 is connected with RF IC card circuit 4 by wire 3 with lower stationary contact 2, RF IC card circuit 4 is connected with RF IC card antenna 5, card reading antennas 6 is connected with system, control circuit 9 by card reading circuit 7, and system, control circuit 9 is also connected with warning circuit 8。
Shown in Fig. 2: press button 13 is arranged between automotive hub 14 and interior tire, RF IC card antenna 5 is arranged on the lower end of axletree 15, card reading antennas 6 is arranged in brake hubs, and corresponding with the position of the RF IC card antenna 5 on axletree 15, and wire 3 is inlayed and is arranged in axletree 15。
The operation principle of the present invention is as follows: when tire pressure is when normal pressure, the spring 10 of press button 13 makes movable contact 12 in the centre position of upper stationary contact 1 with lower stationary contact 2, cause that RF IC card circuit 4 can not work, RF IC card antenna 5 can not launch radiofrequency signal to card reading antennas 6, card reading antennas 6 does not have signal to receive, warning circuit 8 is not reported to the police, and vehicle normally continues to travel。
If in the process of moving, tire pressure is excessive, the connecting rod 11 making press button 13 drives movable contact 12 and lower stationary contact 2 to close, cause that RF IC card circuit 4 works, RF IC card antenna 5 launches a radiofrequency signal to card reading antennas 6, card reading circuit 7 sends one to system, control circuit 9 after reading this radiofrequency signal and starts alarm signal, and system, control circuit 9 starts warning circuit 8, and warning circuit 8 sends warning。
If in the process of moving, tire pressure is too small, spring 10 makes the connecting rod 11 of press button 13 drive movable contact 12 and upper stationary contact 1 to close, cause that RF IC card circuit 4 works, RF IC card antenna 5 launches a radiofrequency signal to card reading antennas 6, card reading circuit 7 sends one to system, control circuit 9 after reading this radiofrequency signal and starts alarm signal, and system, control circuit 9 starts warning circuit 8, and warning circuit 8 sends warning。
So, RF IC card circuit 4, card reading circuit 7 and press button 13 are adopted, it is achieved that the on-line real-time measuremen of tire pressure。
