Embodiment Construction

[0032] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only some, not all, embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without creative efforts fall within the protection scope of the present invention.

[0033] Such as image 3 As shown, the embodiment of the present invention provides a hostless reversing radar system, which includes 2-4 sensors and alarm devices. Each sensor includes an ID pin, a ground pin, a data pin, and a power pin. The data pins of each sensor are respectively connected to a communication bus, and the ground pins and power supply pins of each sensor are ground wires and power wires respectively;

[0034] One of the sensors is used as the ma...

Abstract

A hostless parking sensor system comprises two to four sensors and a warning device, wherein each sensor comprises an ID pin, a grounding pin, a data pin and a power pin, the data pin of each sensor is connected with a communication bus, the grounding pin and the power pin of each sensor are connected with a grounding line and a power line respectively, one sensor serves as the main sensor, and other sensors serve as auxiliary sensors; the ID pin of the main sensor is connected with the warning device, the ID pins of the auxiliary sensors are connected with the grounding line or the communication buses or not wired, and the sensors allocate addresses to themselves according to the wiring states of the ID pins of themselves. According to the system, the main sensor is connected with the auxiliary sensors in parallel, so that normal work of other sensors is not affected when any auxiliary sensor fails; the main sensor acquires the operating states of the auxiliary sensors in real time, so that the position of the auxiliary sensor which fails is judged accurately after the auxiliary sensor fails.

Description

technical field [0001] The invention relates to a vehicle-mounted radar system, in particular to a reversing radar system without a host. Background technique [0002] With the development of automotive electronics, car reversing safety has become an important development direction of automotive electronics. The reversing radar has been widely used in various levels of vehicles, and the reversing radar system provided by the existing technology is mostly connected in series. Sensors, So there are the following flaws: [0003] 1. If any one sensor fails, the communication of the whole system will be interrupted and the system will not work. [0004] 2. After a fault occurs, it is impossible to accurately locate the location of the fault, and it is impossible to eliminate and repair it in time. [0005] like figure 1 As shown in FIG. 1 , it is a hostless radar system in which communication lines are connected in series provided in the prior art, and the sensors are connect...
