Description :

Qingdao Hesheng Zhiyuan Automation System Co., LtdSteam prepayment remote management, smart heating network for thermal power plants, general steam energy charging methodTechnical 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 Zhiyuan Instrument Steam Prepaid Remote ManagementThe 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 GPRS wireless data remote meter reading system is designed and developed by our company to solve the above problems. It ensures the safe operation of the heating network system, facilitates the reasonable allocation of energy, is economical and practical, and can detect problems in a timely manner to reduce losses. The phenomenon of "steam (water) confusion" has taken the management of the heating network to a higher level, achieving the goal of seeking benefits from management. If there is a gas flow meter on site, we do not need to use our flow integrator. Only the on-site flow meter needs to have RS485 communication function. We have developed communication software based on the communication protocol of the meter, and directly connected it to the IC card controller with RS485 line. The main station software is based on the Windows XP system, with intuitive interface and simple operation. Implement timed data collection for data collection

　　Qingdao Hesheng Smart Heating Network Heating User Management: 1. Basic information management of heating users, including user name, number, person, method, pipe diameter and wall thickness, metering equipment form (vortex street, orifice plate, etc.), declared steam consumption, commonly used steam consumption, etc. 2. Analyze the proportion of key users in branch lines, main lines, and overall thermal users, and provide scheduling optimization suggestions based on historical data and other factors to assess the impact of key user start stop on corresponding pipeline parameters. 3. Analysis report on peak and valley flow of hot users, statistics on load situation, and analysis to assist in formulating business plans. 4. Comparative analysis of temperature, pressure, and flow curves of thermal users with similar pipelines and diameters to assist in identifying pipeline anomalies.

　　fiveSteam prepayment remote managementIt can automatically generate various production reports and statistical reports of user's steam consumption, so that the supervisor can timely grasp the thermal production situation, timely solve various problems encountered in production, calmly realize the centralized dispatching management of colleges and universities, change the past passive management mode to the active management mode, and replace it with a new computer information management, query and statistics: it can query and display the data of each instrument at any time in a certain period, so as to facilitate the assessment and query of each shift. All meters transmit data to the on-site acquisition terminal through the rs485 line, and then transmit the data to the control room through independent and network access to the system master station, avoiding the external signals and the * * * * * * * of the external network, and the stability and security of data transmission. At the same time, it also has interfaces and redundancy with other networks

　　At present, most heating companies supply steam first and then settle monthly when selling steam, but this may result in some user units defaulting on steam payments, causing inconvenience to heating companies. The steam IC card prepayment control system developed by Qingdao Hesheng Company can effectively eliminate the above-mentioned problems. The steam users of this system must pay in advance and recharge before opening the valve to use steam. They must also renew and recharge before the balance is exhausted. When the balance is insufficient, local and remote notifications will be sent to remind users to pay in a timely manner. If the balance is not renewed in time, the system will automatically close the valve and stop steam when the balance is zero, eliminating the phenomenon of overdue payment by the steam users. combineSteam prepayment remote managementReal time customer gas usage status, the system control box has unboxing and disconnection reports. Once a customer opens the metering box or system control box without authorization, the data will be immediately transmitted to the control center to remind the staff of the time, and the electric valve will be remotely controlled to close and stop the steam supply, which will have a deterrent effect on malicious behavior by users.
