Problems solved by technology
The radar system with the host has a dedicated controller to configure multiple ultrasonic probes, but configuring the controller will increase the cost and increase the power consumption of the vehicle, and all the ultrasonic probes are connected to the controller in parallel through the wiring harness, resulting in the design of the wiring harness. , The installation of the whole vehicle and the layout of the wiring harness are complex and cumbersome, which is contrary to the current development trend of automotive electronics towards low energy consumption, lightweight, and miniaturization
The hostless radar system uses the LIN (Local Interconnect Network) communication method to assign addresses to determine the main sensor and auxiliary sensor, which need to communicate with the vehicle through the controller of the vehicle body or other controllers. The signal transmission speed is slow, the signal is unstable, and the scalability and compatibility of the radar system are also poor

The embodiment of the invention discloses a radar sensor and a hostless multi-probe radar system, and relates to the technical field of electronic safety detection. The radar sensor comprises a connector, an addressing circuit, a power supply voltage stabilizing circuit and a micro-control unit; the connector is provided with a PWR port, a DATA port, an ID port and a GND port; the connector is connected to the addressing circuit, and the addressing circuit is connected to the micro-control unit; and the addressing circuit is used for providing a sampling level for the micro-control unit so asto identify the position of the radar sensor. According to the radar sensor and the hostless multi-probe radar system, a plurality of combination modes of connection between the port of the connectorand the signal wire harness are used, so the radar system can achieve addressing discrimination of radar sensors in all directions, is simple in structure, convenient to install, short in developmentperiod and good in expandability and compatibility, can be configured with a large number of radar sensors at the same time, can support two-way communication of various communication protocols, and is high and stable in signal transmission speed.
Description
technical field [0001] The embodiment of the present application relates to the technical field of electronic safety detection, in particular to a radar sensor and a hostless multi-probe radar system. Background technique [0002] With the development of electronic technology, radar systems are now widely used, especially in vehicles. Vehicle radar systems are mainly used in ADAS (Advanced Driver Assistance Systems, Advanced Driver Assistance Systems) to detect the orientation of obstacles around the vehicle body. and distance to provide operational reference for the driver of the vehicle. The traditional vehicle radar system is mainly based on the ultrasonic reversing radar. The ultrasonic vehicle radar transmits an ultrasonic wave of a specific frequency to the surroundings of the vehicle body through the ultrasonic probe, and receives the ultrasonic signal reflected by the obstacle, and then amplifies the returned ultrasonic signal through the amplifier. The central proc...
