Pre paid heating system for the park, smart heating network for heating, and meter reading system for the heating industry

Description :

Pre paid heating system for the park, smart heating network for heating, and meter reading system for the heating industryOperation and maintenance management: 1. Establish equipment ledger, record and provide equipment information, reflect the basic parameters, operation and maintenance history of equipment, provide necessary information for daily maintenance and management of equipment, and analyze and manage equipment life and inspection cycle based on the online operation status and equipment ledger of equipment. 2. The equipment ledger should include: basic equipment information, equipment technical specifications, equipment defect records, measurement equipment inspection records, equipment changes, equipment spare parts, equipment ledger queries, and other functions. 3. The seamless integration of equipment ledger and real-time system enables the static and dynamic information of online devices. 4. Defect management includes: defect registration through the inspection system, defect information flow (upgrading, downgrading, forwarding, extension, etc.), defect information statistics, etc; The processed defects are automatically archived in the corresponding equipment ledger, and the phenomena, causes, and defect elimination measures of the faults during the defect handling process can be archived in the equipment fault library. 5. The responsible department and person for defect review and handling can be defined in the system, and the reported defect information will be automatically transmitted to the department for personnel to verify the defects. For confirmed defects, a defect elimination process can be generated for processing.

　　6. Introduction to Smart Heating Network Functions: When a user manually invades the workstation and changes the working status of on-site sensors, the control box can make logical judgments, issue execution commands, and close valves. Its main functions are as follows: file management function (1) operator file: establish login username and password, and grant corresponding operation permissions. (2) Terminal profile: Information parameters for registering a terminal. (3) Meter file: Register information of all meters, real-time and historical curves: can combine topographic maps and monitoring point distribution maps, use real-time or historical data of monitoring points to provide real-time data for management personnel, and play a certain role in managing resources for management personnel

　　Distributed energy systems, as energy supply centers serving the local area, directly face the needs of local users and are deployed near them. This simplifies the energy transmission process for users, reducing energy losses and transmission costs, and increasing the safety of energy supply for users. Due to its lack of large-scale and long-distance energy output mode, it mainly targets the energy needs of local users,Pre paid heating system for the parkThe scale will be constrained by user demand, and compared to traditional centralized energy supply systems, it is of medium to small capacity. Overdraft function: You can choose the "Overdraft" function, which allows certain overdraft limits 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. The pressure change is within the parameter range set by the user, improving the efficiency of the network operation. At the same time, it should also have the function of opening the electric control valve according to the time setting, effectively preventing water hammer and cavitation caused by long pipelines, increasing or extending the service life of electric actuators and valves, and small flow protection function: when the actual flow rate of the user is lower than the small limit value (lower limit of the flow meter), it will automatically meter and charge according to the lower limit flow rate. When the user's actual traffic returns to normal, automatic billing will be based on the actual traffic measurement

　　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.

Automatic printing function can be set, and extended functions can be compatible with any flow sensor, electric control valve, etc. for easy replacement in the future

　　Qingdao Zhiyuan InstrumentPre paid heating system for the parkWorking Principle:

　　The prepayment system for heating in the park reads data (instantaneous flow, cumulative flow, pressure, temperature, etc.) from the flow accumulator, inputs the pre purchased steam consumption (tons) into the specific memory of the control instrument, and processes the two sets of data through internal CPU calculation, comparison, logical judgment, and a series of other processes. When the cumulative flow of the accumulator increases by one ton, the remaining amount (recharge quantity) in the IC card controller decreases by one ton. When the remaining amount decreases to the reported amount (set according to the user's actual situation), the buzzer inside the instrument will sound an alarm to notify the user in advance to recharge in a timely manner. When the remaining amount decreases to zero, the IC card controller will automatically close the control valve and stop the steam supply. Uninterruptible power supply: The equipment shall operate for no less than 3 days after power failure. When the working power supply fails, the system should be able to automatically switch to uninterrupted power supply at the same time as reporting, without affecting the normal operation of other modules in the cabinet. The power-off signal status should be sent to the control center for reporting. Based on a microprocessor, it has complete functions, communication capabilities, and can cooperate with various flow transmitters and sensors for steam flow measurement. It has good electromagnetic compatibility and reliability
