Mine hydrological monitoring system, coal prices hydrological monitoring system, coal hydrological monitoring system manufacturers Tarzan opened Electric Company is a specialized production of coal mining equipment company, located at the foot of Mount Tai, has a 15 year history, the company as Shandong University, Shandong University of Science and Technology The research base, relying on years of college talent and strong technical strength, to "improve the lives of people with advanced automatic control technology, work environment" for business purposes, the development of the "hydrological monitoring system" product users all over the country 25 provinces (including autonomous regions and municipalities), for the industrial and mining production safety, energy consumption and improve productivity to provide effective protection. I. System Overview With the development of modern communications technology and test and measurement technology, the "digital water hydrology," the time has come. Using Ethernet, GPRS and GSM and other advanced communication methods, real-time monitoring rivers, water conservancy operation of lakes, reservoirs, and timely response to the hydrological characteristics of each waters to the relevant departments to make arrangements to prevent the occurrence of floods accident. While improving observation, measurement staff work environment, so that unattended, achieve real-time, accurate, efficient, centralized management results. Second, the principle of water conservancy system components automatic hydrological monitoring and alarm system monitoring sub-station by the observation point and control room monitoring center. Each observation point monitoring sub-station communication with the monitoring center can choose Ethernet, GPRS and GSM communication method according to need. Each observation point monitoring sub-station according to the actual needs of the corresponding sensor, remote terminal (including acquisition modules, memory modules and communication modules), batteries, lightning protection and grounding equipment systems and other components. There are a host control center monitoring and management software. Taian Electric Co. opened to the advanced management model and philosophy, highly qualified professional personnel and excellent product quality and service philosophy to ensure that customers provide the best quality service.
