Problems solved by technology

Due to the differences in batches, circuit parameters, and use environments of the sensing modules themselves, it is difficult to make an accurate judgment on the short-range blind spots of each moving object sensing module, including the sensing angle and range.
If the product is in use, such as improper installation and debugging, sometimes even the short-distance induction failure occurs

Embodiment Construction

[0018] The technical solutions of the present invention will be described in detail below in conjunction with the accompanying drawings and embodiments.

[0019] see figure 1 , figure 2 and image 3 As shown, the moving object sensing module according to the embodiment of the present invention is a circuit module that senses moving objects and outputs low-frequency sensing signals; the circuit module includes an aluminum shell 3 and double-sided circuit boards 1 and 2 . The aluminum shell 3 supports and fixes two circuit boards, which are located in the center of the module. The space between the shell and the circuit board 23 generates a high-frequency detection signal of 8-12GH, which is output to the induction antenna circuit board 1 through 25, and the induction signal passes through the circuit The board 26 is input to the mixer 24, and the mixed frequency difference signal is output by 22-3. The induction antenna circuit board 1 is placed in front of the aluminum she...

Abstract

A moving object sensor module is a circuit module which can sense a moving object and output a low frequency induction signal. The circuit module includes an aluminum housing, and two double-sided circuit boards, wherein the aluminum housing supports and fixes the two circuit boards; one circuit board is a high-frequency signal detection circuit board, and the other circuit board is an inductive antenna circuit board; the inductive antenna circuit board is positioned on the front side of the aluminum housing, a copper foil on the inductive antenna circuit board forms inductive antennas, and the inductive antennas are arranged on intersection points between a X and Y axis coordinate and a circle, wherein the X axis and Y axis have a slant angle of 45 degrees; a square antenna allows the dead centre of the circuit board to form a cross-shaped inductive zone; the radius of the circle can be adjusted to change the positions of the intersection points between the circle and the coordinate so as to change the arrangement positions of the inductive antennas; the sensor module can adjust the induction angle and the induction range of the moving object by changing the positions of the inductive antenna.

Description

technical field [0001] The invention relates to a detection and induction technology for moving objects, in particular to a moving object induction module of an independent induction antenna circuit board. Background technique [0002] According to the Doppler principle, high-frequency microwave detection signals are used to transmit and receive antennas through the copper foil on the circuit board to realize the sensing module for detecting moving objects, which is currently widely used. Generally, the high-frequency detection circuit and the induction antenna circuit are designed on the same circuit board. The middle part of the circuit board is a high-frequency circuit, and the induction antenna is arranged on the left and right sides. This design structure makes the horizontal angle and vertical angle of the module's induction of moving objects The angles are not equal, generally the horizontal angle is greater than the vertical angle, and the sensing range of the module...
