Overheated steam prepayment system, hot water intelligent heating network, terminal function of thermal power plant

Description :

Qingdao Zhiyuan Instrument Overheated Steam Prepaid SystemThe task undertaken by the metering station is to measure various operational parameters of the flow meter system on site. Measurement: Measure the instantaneous flow rate, pressure, and temperature signals of on-site sensors, perform compensation density calculations, and calculate the required cumulative flow rate according to algorithms. Collect on-site power status, valve status, power-off/power on time, prepaid steam balance, settlement balance, instrument parameter report information, programming times, etc., and package these data together with measurement information. Within the same time granted by GPS, transmit the data of each point to the GPRS/CDMA communication module through data lines. The core of the RS485 wired data remote meter reading system is computer network and communication technology. Currently, the most commonly used communication methods include twisted pair cables, optical fibers, and other communication methods. In the late 1980s and early 1990s, pilot work began on automated meter reading systems. Various power supply enterprises across the country have basically established wireless power load control systems. Although their main construction purpose is to control loads, they are gradually being used for reading electricity meters for large users

Establish equipment ledger, record and provide equipment information, reflect the basic parameters, operation and maintenance history of equipment, provide necessary information for daily maintenance and management of equipment, and analyze and manage equipment life and inspection cycle based on the online operation status and equipment ledger of equipment. 2. The equipment ledger should include: basic equipment information, equipment technical specifications, equipment defect records, measurement equipment inspection records, equipment changes, equipment spare parts, equipment ledger queries, and other functions. 3. The seamless integration of equipment ledger and real-time system enables the static and dynamic information of online devices. 4. Defect management includes: defect registration through the inspection system, defect information flow (upgrading, downgrading, forwarding, extension, etc.), defect information statistics, etc; The processed defects are automatically archived in the corresponding equipment ledger, and the phenomena, causes, and defect elimination measures of the faults during the defect handling process can be archived in the equipment fault library. 5. The responsible department and person for defect review and handling can be defined in the system, and the reported defect information will be automatically transmitted to the department for personnel to verify the defects. For confirmed defects, a defect elimination process can be generated for processing.

　　6. The operation of steam metering management equipment on cloud platforms requires the insertion of a device card to modify parameters, which is more password protected than usual. The IC card prepaid system consists of a prepaid control box; Explosion proof (explosion-proof) electric control valve; Card reader/writer (including recharge software); Items 1, 2, and 3 are installed at the on-site measurement point, while item 3 is installed on the office computer of the management personnel.

　　Qingdao Hesheng Zhiyuan Automation System Co., LtdOverheated steam prepayment system, hot water intelligent heating network, terminal function of thermal power plantTechnical specifications for measuring instrument stations: The measuring station is installed in the factory of the steam unit, with one set per unit, including intelligent flow integrator, 4G module, antenna, data cable, unboxing equipment, DC backup power supply (UPS), wall mounted instrument box, and power distribution system. All devices should have replaceability and universality. The above devices need to be integrated into one chassis, and the connections between devices have been integrated and debugged as a whole before leaving the factory; Protection level IP65. Adopt protective measures such as pressure-sensitive and TVS to deal with and solve potential accidents such as voltage fluctuations, vibrations, electromagnetics, and lightning strikes in the power grid.

　　Qingdao Hesheng Zhiyuan Automation System Co., LtdOverheated steam prepayment systemEquipped with RS232/RS485 standard communication interface and MODBUS RTU, MODBUS ASC Ⅱ industrial standard communication protocol, it can communicate with intelligent flow meters, read various measurement parameters and working parameters in intelligent flow meters.

　　1. The device has automatic dialing and disconnection redialing functions. In case of unstable network conditions, it has the ability to automatically restore communication, and the system works stably without human intervention; When the signal in the area is weak, the module can communicate normally by changing the signal reception and transmission strength of the module.

　　2. Online query function can be achieved through the Internet, and users only need to provide their username and password. The real-time online query function can be completed.

　　3. Equipped with data cable and 12VDC power supply.Overheated steam prepayment system, hot water intelligent heating network, terminal function of thermal power plantWhen the cumulative flow rate of the accumulator increases by one ton, the remaining amount (recharge quantity) in the IC card controller decreases by one ton, and the pressure changes within the parameter range set by the user, improving the efficiency of pipeline operation. At the same time, it should also have the function of opening the electric control valve according to the time setting, effectively preventing water hammer and cavitation caused by excessively long pipelines, and increasing or extending the service life of electric actuators and valves
