In electric power system, temperature is a key parameter that represents the normal or abnormal operating condition of the devices. With the progress of science and technology, the social electrical load shows an increasing momentum, and to prevent the fire breakout or explosion caused by equipments heat rising, the automatic monitoring of temperature becomes one of the important measures to maintain safety production and cut loss for all various industries. The traditional temperature monitoring method posses a series of disadvantages: long cycle, complicated construction, low efficiency, inconvenient management, and when malfunction occurs, it will cost a large amount of manpower and material resources to locate the trouble and lay the cables. However, under particular circumstances of monitoring points decentralization, environmental isolation or the existing high voltage, plenty of monitoring methods cannot realize the measurement purpose at all.

AT-II wireless temperature monitoring system is an independent research and development product designed by our company with a sequence of advantages: high measuring accuracy, high reliability, easy installation. It adopts advanced and mature sensor technology and unique advanced wireless communication technology to conduct high voltage isolation & signal transmission, by utilizing its inherent insurability and anti-electromagnetic interference ability, fundamentally solves the temperature monitoring difficulty of electrical contacts in high voltage switch cabinet.

The system mainly comprises of three parts: the front end temperature acquisition device (wireless temperature sensor), the temperature measurement communication terminal (wireless temperature displays), and the temperature monitoring & warning workstation, as shown in figure 1-1-1. AT-II wireless temperature sensor(s) first measure the temperature of the monitoring points, and then send the temperature data to the temperature measurement communication terminals (wireless temperature displays) via wireless mode. Through bus connection, the temperature monitoring computer collects all the operating temperature data of different monitoring points from the temperature measurement communication terminal, and saves it in the database for long term storage, real-time displays the temperature variation curves of the monitoring points and for analysis, once a discovery of temperature overheat or temperature surge to the preset alarm temperature value, alert will be launched promptly. Meanwhile, the access to network for the host computer that saves the temperature data is convenient and feasible, reserved for web page publishing.

The application of this system could be classified into two aspects: civil use and industrial use. Civil use mainly suits for indoor temperature monitoring fields, while industrial use is mainly applicable for electrical power, iron and steel smelting, petrochemical etc. fields; it is capable to conduct real-time temperature monitoring on the high voltage cable joints and high voltage switchgear electric contacts etc., facilitates the operation and maintenance personnel to have a command of the on-site operating situations remotely. 

Wireless Temperature Sensors/Transmitters

¿. Brief Introduction of the AT-II Wireless Temperature Sensors

AT-II wireless temperature sensors are independent research and development front end temperature acquisition devices designed by our company. Thereinto, the AT-II wireless temperature sensors are composed of three parts: the control unit (CU), the wireless data transmission module & the temperature detection part. When the AT-II wireless temperature has measured the temperature, it will then send the relevant temperature data to the temperature measurement communication terminal (wireless temperature display) via wireless mode. The AT-II wireless temperature sensors are mainly installed on the surface of the following objects that are easy to generate heat: cable joints, transformers and switches. Each wireless temperature sensor enjoys a unique ID number. During the practical installation or use, the installation site of each sensor needs to be recorded, and together with its ID number, inputted into the database of temperature monitoring workstation. The sensors automatically transmit the monitoring points’ temperature data one time at regular intervals (measurement cycle could be set in advance); an alarm will be given immediately once a discovery of abnormal temperature, no restriction to the transmission cycle.

Real Time Remote Indoor Temperature Wireless Monitoring System



Wireless temperature acquisition system rose in recent years. It is mainly used for central heating, central cooling, and storage. It can be used in industrial areas as well. Its advantage is monitoring different temperature in the wire unreachable points with low cost; therefore it controls air conditions and heating apparatus to achieve Low Energy Consumption, High Efficiency. Presently, many property companies use manual surveying ways to acquire data during heating (cooling) period, the laborious data collection is not timely and cannot be connected with automatic equipments as well. This system will help operators get the temperature conditions online from remote areas, formulate the reasonable automatic operation scheme, thus adjusting the operation of heat points, and controlling the temperature, which decreases the energy consumption from 8% to 15%.
Owning to the rapid development of economy, energy shortage is becoming increasingly conspicuous. It becomes one of the most important factors that constrain economic development. On one hand, energy supply is in tense situation; on the other hand, due to boosting economy, the low efficiency of energy utilization, high waste, and heavy environmental burden, the energy efficiency rate of our country is 33%, which is 10% lower than international advanced standard Main units energy consumption is 40% higher than international advanced standard. With the expansion of residential area, the scale of its heating (cooling) supply system is increasing, so is its complexity. Operation adjustment and management present many more complexities. If there is a lack of necessary monitoring devices and technical measures, energy waste is unavoidable. Practices in Shanghai and Guangzhou prove that energy consumption increases 8% when the indoor temperature changes -1 ¿¿ in the summer or +1 ¿¿ in winter. What's more, it is not in accord with the requirements of Hygiene if temperature increases are different between indoor and outdoor air. It is better that the ideal temperature indoor is of 5 — 8¿¿ lower than the outdoor, which requires the heating (cooling)supply system to adjust the  heating (cooling)  scientifically  to the change of temperature both indoors and outdoors.              
Remote wireless temperature acquisition system adopts radio frequency and GPRS wireless communication Technology. It can monitor the real-time temperature in long-distance, then transmit the temperature data to Web server at regularintervals, and publish data through this web server. The user can check the real-time temperature curve of the spot from IE browser just indoors. Remote wireless temperature acquisition system includes site temperature terminal and monitoring software. Site temperature terminal includes temperature sensor and wireless transmission module. Site temperature terminal can setup the temperature acquisition period in accordance with customers' requirements, so as to transfer data to remote data center in specified time interval. After that, it can be showed in data and graph through Web. In this way, you can check the temperature when you login internet. It is a convenient and practical way to get temperature information.
