Embodiment Construction

[0011] The present invention will be further described below in conjunction with the accompanying drawings, but not as a limitation of the present invention.

[0012] Such as figure 1 As shown, the combined instrument system that shields mobile phone signals includes: brake control module BSM, which can detect vehicle speed and collect vehicle speed signals; body control module BCM, which has a gateway that can connect The signal is transferred to the low-speed network (B-CAN), where for C-CAN, the baud rate is greater than or equal to 125kbps, and for B-CAN, the baud rate is less than 125kbps; the microprocessor (ICM) of the vehicle instrument cluster, which can Carry out logical judgment; the wireless transmission module that emits radio signals is set in the combination instrument and is a part of the combination instrument. Compared with other ordinary instruments, the electronic components required by the wireless transmission module are added to the PCB of the instrument...

Abstract

The invention provides a combined instrument system capable of shielding mobile phone signals for a vehicle. The system comprises a vehicle brake control module (BSM) for acquiring speed signals, a body control module (BCM) connected with the BSM, a combined instrument connected with the BCM, and a system switch, wherein the combined instrument is provided with a microprocessor and can read the speed signals and perform logic judgment on the received data, and a radio transmission module for transmitting radio signals is also arranged in the combined instrument; and when the switch is started and the speed is more than 5km / h, the radio transmission module is activated to transmit the mobile phone shielding signals. The system has stable working performance, simple structure and low cost, and can effectively reduce the risks of traffic accidents.

Description

technical field [0001] The invention relates to a mobile phone signal interference system, in particular to a combined instrument system capable of shielding mobile phone signals for vehicles. Background technique [0002] Statistics from the transportation department show that the use of mobile phones while driving has the same impact on the driver's judgment and reaction time as drunk driving. In the case of increasing car ownership year by year, vehicle accidents are also emerging one after another, among which traffic accidents caused by answering and calling while driving account for a considerable proportion. The driver answers the phone while driving, which has constituted a potential hazard to road traffic and personal safety. Contents of the invention [0003] The present invention is proposed in view of the above problems, and provides a combination instrument system for vehicles that can shield mobile phone signals with stable working performance, simple struct...
