Embodiment Construction

[0034] Please refer to Figure 1A , Figure 1A is a schematic diagram of a blind spot detection system 10 . The blind spot detection system 10 is installed on a vehicle, and is used to sense whether there are vehicles, people and other obstacles in a specific blind spot area, and to issue a warning signal accordingly, so as to avoid traffic accidents caused by drivers' negligence or blind spots. occur. The blind spot detection system 10 includes a control host 100 , wireless signal transceivers TR_1 ˜ TR_n and alarms ALM_1 ˜ ALM_m. The wireless signal transceivers TR_1˜TR_n are installed in the rear (and / or front) bumper of the vehicle, and are used to detect whether there is an obstacle in the blind spot area for the driver using radar sensing technology. Wherein, the wireless signal transceiver TR_1 is a main wireless signal transceiver, which can integrate the data of the wireless signal transceivers TR_2 ˜ TR_n and transmit the data to the control host 100 . The control ...

Abstract

The invention discloses a wireless signal transceiver and a blind spot detection system. The wireless signal transceiver is used for the blind spot detection system, and comprises a first substrate, a radio frequency processing unit and a complex programmable logic device, wherein the radio frequency processing unit is arranged on the first substrate and used for transmitting a wireless signal and receiving a reflected signal of the wireless signal; and the complex programmable logic device is controlled by a digital signal processor and used for controlling the operation of the radio frequency processing unit according to at least one control command of the digital signal processor so as to detect whether an object exists in a specific range. According to the wireless signal transceiver and the blind spot detection system, the manufacturing cost can be reduced, and the volume of the wireless signal transceiver can be effectively reduced.

Description

technical field [0001] The invention relates to a wireless signal transceiver and a blind spot detection system, in particular to a wireless signal transceiver and a blind spot detection system that can reduce manufacturing costs and effectively reduce volume. Background technique [0002] According to statistics, most traffic accidents are related to drivers being distracted while driving. If the driver gets an early warning 0.5 seconds before a possible collision risk, at least 60% of accidents of chasing the vehicle ahead, 30% of head-on collisions or 50% of road-related accidents can be avoided; if the driver gets the early warning one second earlier, 90% of traffic accidents can be avoided. These statistical data show that if the driver's reaction time is improved, the occurrence of traffic accidents will be effectively reduced, and the blind spot detection (Blind Spot Detection, BSD) system is an intelligent vehicle equipment developed under this demand. The blind sp...
