Wireless adaptive temperature sensor with functions of network testing and displaying

Abstract

The invention discloses a wireless adaptive temperature sensor with functions of network testing and displaying, which is sensor equipment with a network signal monitoring function belonging to the technique of low-consumption wireless sensors and developed to meet requirements of common families and institutions on real-time environment monitoring. The sensor program adopts a design scheme including a universal single-chip microcomputer, a liquid control circuit and a wireless ZIGBEE network module. The single-chip microcomputer realizes displaying and intelligent environment monitoring at low consumption by means of enabling management and hibernation algorithm of a power chip, and functions of acquiring the current status of network communication by users, managing a power switch of the sensor, transmitting current displayed temperature readings and the like can be realized easily with external keys. The more advanced ZIGBEE network in wireless sensor networks is adopted, so that data reliability and networking scale adaptability are guaranteed. A display module is designed to better realize a user interaction function of the sensor, while the Kalman filtering algorithm is added to achieve intelligent adjustment of transmitting intervals of nodes, and accordingly true risks of data with transmitting intervals are lowered greatly, operation of a real-time system is more benefited, a function of indoor environment alarming is realized for users, and accordingly the wireless adaptive temperature sensor is capable of detecting temperature and assuming important responsibility of family security.

Description

technical field [0001] The patent of this invention is a device that uses ZIGBEE wireless network technology to monitor the temperature and humidity of the environment. The main technologies include ZIGBEE wireless network communication and control, low-power system architecture, real-time sensor data processing and adaptive periodic transmission algorithm And realize the humanized human-computer interaction interface. Background technique [0002] At present, there are two main applications in the field of environmental monitoring, one is household heating temperature and humidity detection, and the other is temperature and humidity detection in agricultural and industrial production environments. Among them, the indoor heating detection of the family is related to the vital interests of both the residents and the heating party. According to the current heating regulations in Beijing, if the indoor heating temperature does not meet the standard, the household has the right ...

Problems solved by technology

In this way, although the power is saved, many unexpected problems may occur. For example, when the ambient humidity suddenly rises, the sensor fails to alarm in time and causes the loss of goods in the warehouse, or when the temperature in the home rises abnormally, The sensor did not alarm in time, resulting in more serious consequences such as fire
