System overview Wtf1300 series high integrated intelligent water quality automatic monitoring system, based on the normal surface water quality automatic monitoring function, highly integrated main function units of fixed water quality automatic monitoring system, strengthened intelligent means such as remote video, remote sensing field operation environment, remote diagnosis, remote maintenance, etc., in order to achieve the goal of unattended and remote management. It is mainly used to automatically monitor the water quality pollution of the administrative areas at all levels, the target management waters and other important water sections, timely grasp the water quality pollution status of the key sections of the main river basin, early warning, forecast major or watershed water pollution accidents, solve the disputes of water pollution accidents in cross-border administrative areas, and supervise the implementation of the total control system. System composition The automatic water quality station includes water collection unit, water distribution unit, pretreatment unit, detection unit, data acquisition and transmission unit, system control unit and station room, etc. the automatic water quality monitoring system is composed with the data collection and control system of central station. Performance characteristics Ø It has video monitoring system and power environment monitoring system: through setting liquid level sensor, pressure sensor, voltage sensor, temperature and humidity sensor, professional video camera, etc., the operation parameters, environmental parameters of water station and safety of water station are automatically and comprehensively monitored; Ø High remote management and maintenance: it has the functions of equipment operation monitoring, remote control, dynamic display and data management, reducing maintenance quantity, and effectively improving the operation rate and data efficiency of equipment; Ø Simple and practical: the station room adopts container or integrated station room, with an area of not more than 30 square meters, which is convenient for transportation and movement. The station room is made of color steel plate, which has perfect water supply and power supply, lightning protection and grounding, sealing and warmth preservation and network telephone; Ø The installation method is simple: the automatic monitoring system and analysis instrument are the same as the fixed water station, and the instrument is mostly wall mounted; Ø Wide application scope: it is applicable to the construction of water station with limited land area, complex geographical situation, short construction period, relocation or adjustment demand; Ø Safe, stable and reliable ¨ The protection measures of circuit and water circuit shall be strict, effectively preventing circuit fire and pipe bursting; ¨ All designs follow the principle of system stability first, and save manual maintenance workload to the maximum extent; ¨ The system is reliable, durable, anti freezing and lightning protection measures are perfect, and normal operation in harsh environment is guaranteed for a long time; ¨ Advanced multi-level comprehensive lightning protection measures effectively protect system equipment, communication system and instruments from lightning damage; Ø Standard detection principle and analysis method: the monitoring instrument adopts mature analysis method and advanced detection principle to ensure the consistency of measurement results and national standard methods; Ø Accurate monitoring data ¨ The water extraction unit is equipped with cleaning and algae removal functions to ensure the representative of water samples; ¨ Two automatic calibration modes, regular standard liquid comparison and over standard liquid comparison, are provided, which ensure the accuracy of the instrument and greatly reduce the intensity of online monitoring instrument comparison and test by the monitoring department; ¨ The remote quality control system has the function of linear correction to the water quality online monitoring instrument. It can modify the linear coefficient of the instrument itself according to the comparison of standard liquid, and ensure the accuracy of the instrument data; Ø Simple operation: manual and automatic process operation is simple, only five system control buttons can be used to realize the single step work of the system at any time; Ø Automatic sample retention over the standard: when any monitoring factor data exceeds the standard, the sampler can automatically save the test water sample, which provides strong evidence for subsequent cause analysis and responsibility identification. The water samples can be saved by setting the parameters of the sampler. This method is often used to obtain multiple time samples at one time when comparing the data of online monitor and verifying the validity of data; Ø High compatibility and scalability: compatible with the instruments and instruments of various manufacturers in the mainstream market, with stable performance, reasonable structure, low operating cost and small maintenance workload; Ø Multiple transmission modes: support a variety of transmission modes, Ethernet, 3G, GSM, GPRS wireless transmission and satellite communication interface, remote asynchronous multi-point acquisition, data acquisition and monitoring; Ø Small maintenance workload: unattended, automatic operation, automatic algae removal, remote monitoring and automatic calibration, automatic, stable and long-term operation, and professional operation services.
