Host-free parking radar system of series structure

Abstract

The invention discloses a host-free parking radar system of a series structure. The system is provided with a plurality of sensors, at least one alarm, an internal network and an external network; each sensor comprises a microprocessor, a communication module, an ultrasonic sensor, a driving transmitting module and an ultrasonic receiving module; the communication module comprises a first interface module, a second interface module and an analog switch, wherein the first interface module and the second interface module are led outwards respectively to form a first terminal and a second terminal, and the analog switch is connected between the first terminal and the second terminal and enables information of the first terminal and the second terminal to be interconnected; and the first terminal of each sensor is connected with the second terminal of the adjacent sensor through the internal network to form the series structure, and the first terminal or the second terminal of the sensor positioned at the end is connected with the alarm through the external network. The host-free parking radar system has the effects of simplifying wiring harness connection, reducing vehicle body weight, reducing cost and improving the production efficiency and the installation efficiency.

Description

technical field [0001] The invention relates to the field of parking assistance systems, and more specifically relates to a series-structured hostless parking radar system. Background technique [0002] Such as figure 1 As shown, a conventional parking radar system generally includes a control box 81, a plurality of sensors 82 and at least one reminder 83, and the plurality of sensors 82 are respectively connected to the control box 81, and under the control of the control box 81 And mutual coordination work, wherein each sensor 82 respectively detects the data of obstacle and all transmits to control box 81 processing, and this control box 81 analyzes above-mentioned data and judges the distance of obstacle, when the obstacle distance does not satisfy predetermined condition , the control box 81 notifies the reminder 83 and reports to the police. The multiple sensors 82 need to be arranged on the outside of the vehicle body due to work requirements, such as on the front a...
