Problems solved by technology

[0005] For the existing wired remote devices, most of them are bus-type structures, and the number of supported nodes is small. The bus-type structure is limited by the transmission distance of the bus. At most, only one sensing device can be 1200m away from the host device. The structure of the T-head interconnection node has poor stability, is easy to be damaged, and has application limitations such as irregular wiring, so it is difficult to popularize and use

Abstract

The invention discloses a temperature and humidity sensing networking system, which comprises at least one computer, central equipment and a plurality of sensing nodes. The central equipment comprises a serial port and a plurality of node interfaces. The serial port is connected to the computer. The plurality of sensing nodes are connected to the plurality of node interfaces of the central equipment by adopting a star bus. Each sensing node comprises a sensing host and a plurality of sensor modules. The sensing host comprises a micro control unit (MCU) processor, a display and a first communication interface. Each sensor module comprises a temperature and humidity data acquisition chip and a second communication interface. The plurality of sensor modules are concatenated in form of tail-biting structure by the second communication interfaces, and then are connected to the first communication interface of the sensing host. The temperature and humidity sensing networking system can conveniently monitor distributed temperature and humidity information in real time, has high reliability, high cost performance, high extensibility and high portability, and enables a user to realize corresponding temperature and humidity data acquisition and transmission functions only by arranging required sensing modules.

Description

【Technical field】 [0001] The invention relates to the technical field of monitoring, and more specifically, relates to a system capable of simultaneously measuring temperature and humidity. 【Background technique】 [0002] Temperature and humidity monitoring has been widely used in human daily life, and its application fields include crop production, medicine and health, food and other industries. With the rapid development and popularization of science and technology, there are more and more high-performance equipment, and the requirements for temperature and humidity in all walks of life are also getting higher and higher. At present, there are two main types of real-time temperature and humidity detection: [0003] 1. Manually measure the temperature and humidity on the spot. This method is labor-intensive and lacks economic effectiveness; [0004] 2. Use wireless or wired remote automatic real-time temperature and humidity collection. Usually, a computer terminal will b...
