The role of the cooling tower is to exchange heat with the cooling water that carries the waste heat inside the tower body, so that the waste heat is transferred to the air and dispersed into the atmosphere. Widely used in air conditioning cooling systems, frozen series, injection molding, leather, foaming, power generation, steam turbines, aluminum processing, air compressors, industrial water cooling and other fields. In the cooling tower operation, sudden accidents such as oil leakage and vibration have caused great harm. With the development of the technology of the Internet of Things, the cooling tower remote monitoring system has emerged as a result of the problem of cooling tower failure.
System function overview: After data collection of the cooling tower equipment, the data is transmitted to the server in real time through the GPRS network, and the user can view the running status of the equipment anytime anywhere. At the same time, when the equipment is running abnormally, the system will automatically send warning information to the user, allowing the user to repair the equipment in advance to prevent further damage to the equipment and ensure safe production.
The system is mainly composed of three parts:
The upper computer software of the control center computer runs, and the cooling tower parameter settings of each area are performed. The real-time data of the site is reported via the GPRS network active online machine. The upper computer software analyzes and reports the reported field data, and on the page The real-time running status is displayed by icons and the corresponding historical data is stored, and special operations can be performed manually.
2, GPRS wireless acquisition controller (4 letter 3G industrial wireless RTU)Sixin 3G Industrial Wireless RTU ---- F2X64 series wireless remote measurement and control terminal is a high-performance monitoring and control device that integrates analog signal acquisition, digital input, digital output, counting and wireless data communication, and can directly access various The analog signals, level signals, dry contacts, and pulse signals output by sensors, standard transmitter signals, meters, etc., are transmitted to the monitoring center via the GPRS wireless network, and the digital transmission function of the direct monitoring center is realized by on-site acquisition.
The topology is as follows:
Nowadays, users buying a new type of Bluetooth Speaker are not only based on functional considerations to meet product requirements, but their biggest purchase motivation, their inner psychological appeal and emotional resonance are one of the motives.
What are the characteristics/attributes of Bluetooth speakers?
