Description

technical field

[0001] The present invention relates to a reversing radar device without a control box, in particular to a reversing radar composed of master / slave sensors; The function of slave sensors to work and collect their detection results. Background technique

[0002] Due to the development of electronic technology, the general public can enjoy the convenience and assistance brought by the development of technology. For example, reversing radar is a very specific example. The car owner installs the reversing radar on his car. When reversing or parking on the roadside, the obstacle detection function of the reversing radar can be used to assist him to complete the reversing or parking smoothly. The sensitivity of the reversing sensor and the installation setting and sensing There is a direct relationship between the number of devices.

[0003] like Figure 4 As shown, a control box 80 is generally used to connect several ultrasonic sensors 81 to 84 in a parking ra...
