Wireless device and method for detecting space object and temperature

Abstract

The invention relates to a wireless detecting method and device for a space object and a temperature. The wireless device comprises a local area network composed of a plurality of wireless modules; each wireless module is configured to determine whether a change in a received signal strength is greater than a reference value, thereby determining whether there is an object present or moving betweenthe wireless modules, and collected sensing data is transmitted to other wireless modules. The wireless detecting method and device for the space object and the temperature of the present invention detect the distribution state of an object in a limited space (whether an object exists or moves) and the temperature of a plurality of locations through a plurality of wireless modules, and directly or indirectly wireless-transmit and collect the detection data of each wireless module, so that the status of a specific space can be known at any time.

Description

Technical field [0001] The present invention relates to the field of detection technology, in particular to a wireless detection device and method for space objects and temperature. Background technique [0002] The current methods of detecting space objects are mainly divided into 1.) Active: Use photographic records or ultrasonic sensors to measure distance changes or transmit infrared and receive reflected signals to know whether there are objects in space. 2.) Passive: The object emits a specific radio wave (infrared rays of the human body), the sensor receives it to determine the presence of the person, or the pressure sensor detects the weight of the object. Each method has its own limitations and difficulty in implementation, and most of the data collection is wired or additional wireless transmission transceivers to collect the sensing data, facing the complexity of the layout, cost and energy consumption, and there is no wireless ( RF) own signal (RSSI) as a suitable me...

AI Technical Summary

Problems solved by technology

Various methods have their own limitations and difficulties in implementation, and data collection is mostly done in a wired way or by additionally adding a wireless transmission transceiver to collect sensing data, facing problems such as layout complexity, cost, and energy consumption, and there is no wireless ( RF) own signal (RSSI) as a suitable method for detecting space objects and the practice of planning suitable networks

[0003] The mainstream of short-distance wireless low-power transmission technology includes Wi-Fi, ZigBee and Bluetooth, which is a short-distance (within 100m) transmission communication specification using 2.4G public wireless spectrum, mainly used for data transmission communication applications, Has been widely used in various fields, Wi-Fi, Bluetooth 4.0 and above have indoor positioning specifications and applications (beacon), but there is no standard solution and application for space object detection
