Title: Detection system and method based on wireless network type salinity and temperatureApplicant: Univ JiangsuPatent number: CN101315361Publication date: December 3, 2008

Abstract

The invention discloses a salinity and temperature detection system based on a wireless network type, as well as a detection method. Wireless salinity and temperature sensors are connected to a signal conditioning circuit, the signal conditioning circuit is connected in series with a singlechip and a radio-frequency module to form a sensor node of a pool; the output signals of a plurality of sensor nodes and a plurality of control nodes are sent to a gathering node through the radio-frequency module; the input of each control station is connected with the output of a monitoring center in parallel; and the control nodes are connected with an actuating mechanism. The detection system arranges the gathering node, and the sensor nodes and control nodes within the coverage area to form a star network, and has the high precision sensor signal conditioning circuit and an automatic temperature compensation effect on the salinity detection; the wireless sensor network uses the common 2.4 GHz global public free frequency range; the interference of wireless communication on other equipment are reduced, and the sending power is reduced at the same time.

A reader uses the RFID protocol to wirelessly read the data from the tag.

Title: Embedded type wireless sensing network intelligent platformApplicant: Shanghai Evoc Intelligent TechPatent number: CN101232417Publication date: July 30, 2008

Abstract

An embedded wireless sensing network intelligent platform comprises network nodes, a base station, a wireless gateway, and a central control computer, and carries out communication according to an IEEE802.15.4-based Zigbee communication protocol standard. The technique provides an intelligent platform for an embedded wireless sensing network, which can combine required different sensors according to practical control requirement to develop wireless sensing network systems meeting different requirements. The intelligent platform can thoroughly get rid of a wire access manner adopted in conventional sensing control system, and overcome disadvantages such as wiring difficulty, high cost, and maintenance/management difficulty caused by the wire control manner. The platform has high development flexibility, wide operation and application ranges, low cost of system construction and maintenance. Compared with other wireless control manners, the system networking manner has the advantages of combined short-range multihop and grid manner, high intellectualization and reliability, high stability, low power consumption, and long service life.
