Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of sensors, and more particularly to an induction structure for a microwave intelligent sensor. Background Art
[0002] The microwave intelligent sensor can accurately measure parameters such as the position and distance of a target object by emitting microwaves and receiving the reflected signals. This high-precision measurement feature enables the microwave intelligent sensor to be widely used in fields such as industrial automation and logistics tracking. Different from traditional contact sensors, the microwave intelligent sensor can perform detection without directly contacting the target object, avoiding wear and errors caused by contact. The microwave intelligent sensor utilizes the Doppler effect to accurately identify and measure the speed and direction of a moving object. When an object moves within the detection area, the frequency of the reflected microwave signal will change, and the sensor analyzes this change to determine the motion state of the object.
[0003] Deficiencies of the prior art: Poor received signal means that the microwave signal reflected from the target object by the sensor is weak or interfered, which will cause errors when the sensor measures parameters such as the position, distance, and speed of the target object. A significant advantage of the microwave intelligent sensor is its strong environmental adaptability, enabling it to work normally in harsh environments. However, poor received signal will weaken this advantage, resulting in a decline in the performance of the sensor in environments such as fog, rain, and dust. A microwave intelligent sensor without a backup battery completely relies on external power supply. Once the external power supply is interrupted, the sensor will not be able to work normally, which may lead to the interruption of the monitoring or control system and affect the stability and reliability of the entire system. The external power supply system itself also has the risk of failure, such as power outages, short circuits, and overloads. Once the external power supply system fails, it will directly affect the normal operation of the sensor and may even lead to the paralysis of the entire monitoring or control system. Summary of the Utility Model
[0004] To overcome the above-mentioned defects of the prior art, the utility model provides an induction structure for a microwave intelligent sensor to solve the problems existing in the above background art.

[0022] Among them, a metal antenna sleeve disk 109 is movably sleeved on the outer sidewalls of the microwave transmitter 201, the first microwave receiver 202, and the second microwave receiver 203.
[0023] Among them, a buckle 108 is fixedly connected to the top end of the fixed disk 111.
[0024] Among them, a data power supply line 207 is fixedly connected to the bottom end of the relay 208. A battery fixing block 3 is fixedly connected to the inner sidewall of the inner ring of the sensor 1. An electric contact interface 301 is fixedly connected to the bottom end of the battery fixing block 3.
[0025] Among them, a spare battery 302 is movably connected to the bottom end of the electric contact interface 301.
[0026] Among them, anti-slip patterns 101 are provided on the outer sidewall of the sensor 1. A first thread 102 is provided on the outer sidewall of the sensor 1. A second thread 103 is provided on the outer sidewall of the sensor 1. A battery electric contact housing 106 is threadedly connected to the outer sidewall of the second thread 103. A device connection head 107 is fixedly connected to the bottom end of the battery electric contact housing 106. Anti-slip patterns 101 are provided on the outer sidewall of the sensor 1, which is convenient for holding and installation. At the same time, the protective cover 104 and the battery electric contact housing 106 can be conveniently installed through the first thread 102 and the second thread 103 to protect the internal components from the external environment. A device connection head 107 is provided at the bottom end of the battery electric contact housing 106 for connecting and exchanging data with external devices or systems.
[0027] Among them, a protective cover 104 is threadedly connected to the outer sidewall of the first thread 102.

[0028] Working principle of the present utility model: The sensor 1 receives power supply from an external power source through the data power supply interface 206. At the same time, the backup battery 302 is connected to the main circuit through the contact interface 301 and the battery fixing block 3 and is in a standby state. When the external power source is normal, the backup battery 302 does not work; when the external power source is cut off or the power supply is unstable, the relay 208 will switch to the backup battery 302 for power supply to ensure that the sensor 1 continues to work. The microwave transmitter 201 emits microwave signals to the surrounding environment under the control of the circuit board 2. After the microwave signals encounter the target object, they are reflected back and received by the first microwave receiver 202 and the second microwave receiver 203. These two receivers are located at different positions or angles to obtain more comprehensive reflected signal information. The metal antenna sleeve plate 109 is sleeved outside the microwave transmitter 201, the first microwave receiver 202, and the second microwave receiver 203. As a signal concentrator, it guides the reflected microwave signals more intensively onto the receiving element, thereby improving the sensitivity and quality of the received signals. The microwave detector 204 conducts preliminary detection on the received microwave signals, including measuring parameters such as signal strength and frequency. The signal processor 205 further processes the detected signals, including steps such as filtering, amplification, and demodulation, to extract useful information, such as the distance, speed, and direction of the target object. The processed data is transmitted to an external device or system through the data power supply interface 206 or wirelessly if a wireless communication module is designed for further analysis and application. When the external power source is cut off or the power supply is unstable, the relay 208 automatically switches to the backup battery 302 for power supply to ensure that the sensor 1 can continue to work normally, avoiding data loss and system downtime. For the microwave intelligent sensor 1 device that needs to be frequently moved or carried, the backup battery 302 provides a convenient power solution, making the device more portable and practical.
