GPRS remote meter reading platform, saturated steam energy charging, smart heating network technical specifications

Description :

Due to the relatively dispersed geographical distribution of various automobile enterprises and outdated means of measuring data collection and transmission, manual reading is adopted, with a reading frequency of once a day. This mode results in poor real-time performance of steam metering data, with only one data per day, which is not conducive to data analysis; After instrument malfunctions or unexpected power outages are not detected in a timely manner, they can only be discovered during inspections or meter readings, and the exact time of the malfunction cannot be determined, resulting in delayed maintenance and management. Some companies, for their own interests, manipulate on-site instruments or display devices, which is not conducive to timely problem detection and analysis. This leads to significant discrepancies between the export summary table of the thermal power company and the sub meters of various gas consuming enterprises, resulting in occasional metering and other situations at the end of the month settlement. Qingdao HeshengGPRS remote meter reading platform, saturated steam energy charging, smart heating network technical specificationsReal time dynamic monitoring and management of gas users can be achieved. Provide a more timely data foundation and support platform for steam metering management work.

　　Qingdao Zhiyuan InstrumentTechnical specifications for smart heating networkMain functions: 1. Anti theft function, 2. Prepaid function, 3. Remote meter reading function, 4. Anti strong magnetic, 5. Anti lightning function, 6. Generate various reports, 7. Arrears, reminders, and report information prompt function, 8. GPRS remote meter reading platform, saturated steam energy charging, intelligent heating network technology specification valve position, flow rate and other data upload. The upper computer can set the reporting method arbitrarily. Flexible communication parameter settings: The communication address and baud rate of the prepaid controller can be set as needed (address range: 1-128, baud rates: 2400, 4800, 9600). Data recovery function: In the event of accidental damage to the controller, internal data (mainly user recharge balance) can be restored, effectively avoiding the occurrence of both parties. Report function: automatically generates * *, monthly report, annual report, and can also be used for statistical reporting and printing at any time. Automatic printing function can be set

　　Qingdao Hesheng Zhiyuan Automation System Co., LtdGPRS remote meter reading platform, saturated steam energy charging, smart heating network technical specificationsSystem 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 identity verification, the system can enter. The system defines access permissions based on different access users. The wireless meter reading system terminal adopts a B/S structure and supports intelligent terminals with internet access functions to access, enabling the operation of the heating network anytime, 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. According to the actual situation where various meters are relatively concentrated, the low-level network of the smart heating network technology specification adopts RS485 bus. It has the characteristics of simple structure, low cost, and low wiring requirements. After the system is established, it realizes the unified reading time of meter values, changes the 15-30 minute manual reading time, achieves fairness in assessment while reducing the labor intensity of personnel, reasonably allocates resources such as personnel, finance, and materials, improves efficiency, and realizes the transformation of economic benefits
