Embodiment Construction

[0022] The present invention will be further described below in conjunction with accompanying drawing.

[0023] see figure 1 , the figure shows a sensor network system for on-site signal detection of the present invention, which includes current and voltage sensors 1, carbon dioxide sensors 2, light intensity sensors 3, temperature and humidity sensors 4, and the four sensors are respectively connected through series Network terminal CPU5 and wireless network transceiver module 6 are connected with a router or coordinator 7, wherein:

[0024] The current and voltage sensor 1 completes the sampling of the current and voltage signals, outputs an analog signal, converts it into a digital signal through A / D (analog / digital) and transmits it to the network terminal CPU3;

[0025] The carbon dioxide sensor 2 completes the sampling of the carbon dioxide concentration signal, outputs an analog signal, and converts it into a digital signal through A / D and transmits it to the network t...

Abstract

The invention discloses a sensor network system for detecting a signal on site. The system comprises a current and voltage sensor, a carbon dioxide sensor, an illumination intensity sensor and a moisture and temperature sensor, wherein the four sensors are connected with a route or coordinator through a network terminal CPU and a wireless network transmitting and receiving module which are serially connected. By using the sensor network system for detecting the signal on site of the invention, the sensors can be arranged flexibly on site, real-time data and historic records of the sensor can be stably, reliably and randomly sampled, and particularly the system contributes to the on-line detection and wide area measurement of intelligent power grids and intelligent buildings.

Description

technical field [0001] The invention relates to a wireless sensor network system, in particular to a sensor network system for field signal detection. technical background [0002] On-line detection and wide-area measurement are extremely important components in the smart grid and smart building systems. A sensor system is needed to overcome the disadvantages of traditional systems: [0003] The installation arrangement is limited by the location structure. [0004] Synchronization, stability and reliability of sampling data. [0005] Real-time data and historical records cannot be sampled at the same time. Contents of the invention [0006] The purpose of the present invention is to overcome the defects of the prior art, and provide a sensor network system for on-site signal detection, which can flexibly arrange and install sensors on the site, and provide stable and reliable real-time data and historical records of arbitrary sampling sensors, which is especially helpf...
