Design of Steam Prepaid Metering Terminal, Thermal Network Valve Control System, and Smart Heating Network Management Platform

Description :

Design of Steam Prepaid Metering Terminal, Thermal Network Valve Control System, and Smart Heating Network Management PlatformIt combines computer technology, sensor technology, data communication technology, and incorporates prepaid management functions. This prepaid management system is mainly used for monitoring and managing the metering systems of various heat users in industrial parks. It uses the GPRS wireless network platform to send the parameters of each heat network user in the park to the data database on the heat network server in the heat network center through secondary instruments and wireless measurement and control communication modules. And through software, real-time monitoring of user data in the heating network is carried out, with functions such as reporting reminders, trend recording, report statistical analysis, remote recharging, and real-time control of remote electric valves for overdue payments. It assists heating network dispatch and maintenance personnel in ensuring the safety, stability, and energy-saving operation of the heating network, which is a basic prepaid system for remote meter reading in the heating network. The steam metering management terminal purchases gas, recharges heat, inserts cards, and queries with IC card technology. With just one insert, it is easy to handle, transforming the traditional manual meter reading and pricing into user card based gas and heat purchases. This achieves automation in the collection and management process of gas and heating fees, with data storage and backup functions. The system database can be stored locally, and its storage time is determined by demand and computer configuration

Qingdao Zhiyuan Instrument Steam Prepaid Measurement TerminalThe 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. Moreover, the long-distance transmission distance can reach 1200 meters, which can reliably meet the needs of low-level data acquisition and transmission. At the same time, it also helps to reduce the distributed capacitance generated between the two 485 communication lines and the surrounding areas of the communication lines. The GPRS wireless data remote meter reading system was designed and developed by our company to solve the above problems. It ensures the safe operation of the heating network system, facilitates the rational allocation of energy, is economical and practical, and can detect problems in a timely manner to reduce losses. The phenomenon of "confusion of steam (water)" has taken the management to a higher level, achieving the goal of seeking benefits from management. In the late 1980s and early 1990s, the pilot work of automated meter reading system began. 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

　　Qingdao Zhiyuan InstrumentSteam prepayment metering terminalService commitment:

　　From the date of delivery of the heating network system, it enters the after-sales service period. The after-sales service period includes a free warranty period and a quality maintenance period.

　　Free warranty period: Within 12 months from the date of normal use of the product or system, it is a free warranty period. During the free warranty period, any quality issues within the warranty scope will be repaired and replaced by Party B free of charge.

　　Quality maintenance period: After the quality assurance period, we will continue to provide lifetime preferential services. The maintenance services carried out during the quality maintenance period will be charged material and labor costs based on the spare parts product price (not higher than the contract price) and maintenance situation set by the company.

　　The specific service items during the after-sales service period are as follows: receiving letters from users, providing responses or handling suggestions within 24 hours, and ensuring user satisfaction. And store the corresponding information in the user maintenance record sheet.

Automatic printing function and automatic fault reporting function can be set: the monitoring point automatically reports the fault information to the monitoring center and prints the report information automatically. The faults detected automatically include communication failures of flow meters, 220V AC power outages, IC card failures, etc. Various meters transmit data to the on-site collection terminal through RS485 lines, and then transmit the data to the control room through independent and networked access to the system main station, avoiding external signals and network interference, ensuring 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 metering terminalReal 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.
