Implementation Rules for Smart Heating, Smart Heating Network for Thermal Power Plants, Introduction to Superheated Steam Data CollectionPrepaid function

　　Prepaid function, divided into automatic mode and manual mode. Automatic mode: The valve with a remaining capacity is open, and the valve with a remaining capacity of 0 is closed; Manual mode: The valve opening can be adjusted with or without a margin, but when there is no margin, the valve can be manually opened, and the negative value of the margin will be automatically deducted after resetting.

　　Recharge requires 2 people to complete. After the personnel submit the recharge request and confirm its accuracy, they will review and approve it on their own. If there are any errors, the recharge will be rejected; If the personnel confirm that their recharge is correct and approved, then the recharge is successful; If the confirmation is incorrect, the recharge will be rejected. After successful recharge, the recharge information will be sent to the customer via duanxin.

　　For incorrect recharge, if the recharge has been successful, you can operate the red flush setting to clear the recharge. The recharge of -6 in the picture is the red flush setting.

　　Settlement reports can be generated based on custom time periods

　　Rate modification function to meet the demand for adjusting gas source prices in different periods;

Implementation Rules for Qingdao and Shengzhiyuan Smart HeatingPrinciples of Measurement Software Design:

　　The system design follows the basic principles of "mature technology, real-time and fast, economical and practical, easy to expand, and easy to upgrade".

　　2. The on-site measuring instrument technology meets the standard design, and adopts computer remote mode or assisted management mode.

　　3. Adopting a mature fully open, layered, and fully distributed system structure, the system configuration and equipment selection facilitate the expansion of hardware and functionality, and adapt to the rapid development of computer technology. By fully utilizing the technology in the computer field, the system performance can reach the domestic level, ensuring long-term continuous operation of software and hardware, and achieving the goal of "unmanned and few personnel on duty".

　　4. The main network topology of the system adopts DDN network to enable communication between each station system and the central workstation, realizing data monitoring and functions. Information publishing is achieved through IE browsing through WEB Server, supporting remote access by intelligent terminals.

The modern energy management reform is innovative, and data such as valve position and flow rate can be uploaded. The upper computer can set the reporting method arbitrarily. Flexible setting of communication parameters: The communication address and baud rate of the prepaid controller can be set according to needs (address range: 1-128, baud rates: 2400, 4800, 9600). 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 "confusion of steam (water)" has taken the management of the heating network to a higher level, achieving the goal of seeking benefits from management

Implementation Rules for Smart Heating, Smart Heating Network for Thermal Power Plants, Introduction to Superheated Steam Data CollectionThe gradually established thermal user management system includes thermal user data, such as industry classification, gas usage characteristics (intermittent, continuous), and gas usage periods. Through analysis of thermal user data, it guides thermal users to develop reasonable steam usage plans and promotes the day night balance of the total heating load provided by the bidding party; In addition, by understanding the management of heating users and analyzing the possible fluctuations in steam load caused by market and industry influences on heating users in the future, the total steam supply load of the bidding party can be predicted and corresponding steam supply plans can be formulated.

Qingdao Zhiyuan Instrument Intelligent Heating Implementation RulesThe 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. Overdraft function: You can choose the "Overdraft" function, which allows a certain amount of overdraft limit for individual special users. In the event that the user's balance is exhausted, the valve will not be closed, and a certain amount of gas can be overdrawn for use. It has the characteristics of being fast, real-time, etc., and can complete the entire meter reading task. It is generally composed of a system master station and measuring instruments. In the management room, the entire system can be viewed at a glance with the network browsing function, which can achieve 24-hour operation of the heating network. All physical quantity data in the system are displayed on the screen, and users are informed of the parameters of steam and pipeline operation. In the event of a fault*
