KC700 Electrical contact wireless temperature measuring device consists of a wireless temperature sensor, a temperature measurement communication terminal (temperature receiver), and a temperature monitoring and warning workstation.
Wireless temperature sensor: measures the temperature of the contact point. Mainly installed in places that are prone to heat. Each wireless temperature sensor has a unique ID number, and the location where each sensor is installed is recorded during actual installation and stored in the temperature monitoring workstation computer database along with the number. The sensor automatically transmits the temperature data of the monitoring point at regular intervals (can be set in advance), but if the temperature is abnormal, it will immediately alarm and is not subject to the transmission cycle limit.
Temperature measurement system
For the substation that has been put into use, the power distribution room has added a wireless temperature measurement system. The previous solution has to open holes in the switchgear cabinet, install the receiving device, consume a lot of manpower, material and financial resources, and the power outage takes a long time, and requires professionals. Construction is very inconvenient.
The new centralized wireless temperature measurement system is mainly for substations that have been put into use, and the special situation of the wireless temperature measurement system transformation is added to the power distribution room. The new solution is especially suitable for retrofitting existing stations and outdoor equipment for temperature measurement. It is also suitable for new stations. .
1. The amount of the project is small and the switch cabinet is free of holes and wiring, which greatly saves the time and cost of the transformation.
2. Can be displayed in the transformer room, power distribution room, and can be connected to the main station through a variety of communication methods, such as RS-485, fiber, Ethernet communication networking.
3. Powerful, a centralized display device can be configured to receive up to 299 wireless temperature sensors, display intuitive, with database management, historical curve query and other functions. 7-inch large-screen color LCD display, more clear and intuitive.
Working principle
Through the single-chip microprocessor control of the wireless temperature sensor, the temperature of the device under test is converted into a digital signal by the temperature sensor, and then transmitted to the reader through the wireless transmitting and receiving module, and the collected temperature information is transmitted through the 485 through the microprocessor. The module is uploaded to a PC computer.
A plurality of sensing electronic tags are distributed around the reader, and the temperature measuring terminal can be added, deleted, and moved freely within an effective communication range. The reader is installed in the control center. The control center computer software monitors the temperature change at each point in real time. The temperature monitoring computer collects the operating temperature data of each monitoring point from the temperature measuring communication terminal, and saves it in the database for long-term storage. The temperature change curve is analyzed and once the temperature is overheated, or the temperature rises rapidly to the alarm temperature, the alarm is immediately issued, so that the heat of the whole system can be grasped without leaving the house.
