Description :

　　Qingdao Hesheng Zhiyuan Automation System Co., LtdSteam prepaid remote rechargeSystem Introduction:

　　1. Establishment of a prepaid steam metering management center;

　　2. Installation, commissioning, and data transmission of 100 sets of prepaid steam metering equipment;

　　3. The pre charging system for the heating network has opened 100 remote metering points, with N metering points used in the first phase. The excess points will be reserved for future expansion;

　　4. According to the steam parameters provided by Party A, the rated pressure is 2.5Mpa, the upper temperature limit is 320 ℃, the working pressure is 1.2Mpa, and the working temperature is 300 ℃. This data is an important parameter for us to choose a flow meter.

　　5. The steam metering management system can automatically generate various production reports and statistical reports of users' 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 passive management mode to the active management mode, replace it with a new computer information management, based on the gsm network, adopt the packet exchange transmission mode, overcome the shortcomings of the low conversion rate of gsm circuit, poor resource utilization rate and other shortcomings, and limit the use of existing gsm network resources. It has a high transmission rate, short access time, and users are online in real time and charged based on traffic, quickly reducing service costs. It is particularly suitable for sudden small traffic data transmission

Steam prepaid remote recharge, wireless data collection, cloud platform remote meter reading frameworkReal time and historical curves: It can combine topographic maps and monitoring point distribution maps, use real-time or historical data from monitoring points to provide real-time data for management personnel, and play a certain role in managing resources for management personnel. It has the characteristics of being fast, real-time, etc., and can complete the entire meter reading task. Generally composed of a system master station and measuring instruments, valve regulation function 2: over flow limiting function. When the flow exceeds the set value, the valve opening will be automatically reduced. The small flow valve closing function automatically closes the valve when the flow rate remains below the set value for a period of time

　　Qingdao Hesheng Zhiyuan Automation System Co., LtdSteam prepaid remote recharge, wireless data collection, cloud platform remote meter reading frameworkSystem functions:

　　a. Can query historical data of any hot user, any parameter, and any time period, and support the export and printing functions of statistical reports and analysis curves; Rich report customization printing and archiving functions, which can print hot user daily, monthly, and steam consumption detail reports, parent pipe daily, monthly, and summary reports, and can be archived as EXCEL format files (*. xls). b. Hot user management data system, including flow rate, pressure, temperature, upper and lower limit report settings, current operating parameters of instruments, unit price, special policies, responsible person information, etc., to prevent users from modifying settings; c. Access control function: Operators need to apply for a login name with their personal ID when logging in (non ID cannot be applied for), and achieve real name login; After entering the password and passing the identity verification, the system can enter. The system defines access permissions according to different access users. d. The steam charging of the thermal power plant adopts a B/S structure, supporting intelligent terminals with internet access functions to access, enabling the operation of the heating network anytime and anywhere, and achieving mobile office; e. Geographical distribution map of heating network users and routing map of heating network pipelines, which can be drawn according to the needs of the network and marked with steam flow direction (green line in the figure), locate the coordinate points of heating network users, and display the pipeline distance between heating customers and heat sources;

　　f. The security permission setting function of the steam prepaid remote recharge system: The permission setting provides complete security authentication, and users cannot enter the system. Legitimate users can perform corresponding operations according to their permissions. The wireless remote intelligent meter reading system is built on the network of the GPRS data management center established within the enterprise, and transmits all incoming traffic data to the data center through the mobile GPRS network
