Distributed heating network management system, smart heating network for power plants, saturated steam energy charging software

Description :

　　Qingdao Hesheng Zhiyuan Automation System Co., LtdDistributed Heat Network Management SystemUninterruptible 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, and send the power-off signal status to the control center for reporting. GPRS/CDMA wireless data transmission module (DTU): The wireless communication device used utilizes 3G/4G mobile network as the carrier network to achieve remote wireless transmission of data. It connects the remote control station with the central control system and is used to remotely transmit steam metering data to the steam metering system, achieving remote access between industrial Ethernet network devices. Using RS485 interface and communicating with its compensator, the collected signals are transmitted to the central control system to achieve machine to machine data communication based on standard TCP/IP protocol. GPRS/CDMA data cards are required, and the specific requirements for the data cards will be proposed by the seller, which will be handled by the buyer at the communication company. Qingdao Zhiyuan Instrument STR/EF-II/TCP Fault Automatic Reporting Function: 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. The report function automatically generates * * *, monthly reports, annual reports, and can also be used for statistical reporting and printing at any time. Automatic printing function can be set, and the backup power supply is flexible: an external battery is used, and different battery capacities can be selected according to actual needs. When the external power supply (AC220V) is interrupted, the system's instruments (flow integrator, prepaid meter), GPRS or CDMA modules can be maintained to work continuously.

　　With the trend of informationization and intelligence development in the heating network, the existing heating network collection system is no longer suitable for new intelligent management requirements. It is necessary to upgrade and add functions to the existing hardware and software systems to build a smart heating network management system.Distributed Heat Network Management SystemThe intelligent meter reading system is developed using modern scientific technology, and can directly rely on system calculations in both the reading and cost measurement stages. Therefore, the automation level of the intelligent meter reading system is much higher than that of traditional meter reading, and the backup power source is flexible. It adopts an external battery, which can be selected with different battery capacities according to actual needs. When the external power supply (AC220V) is interrupted, it can maintain the continuous operation of the system's instruments (flow integrator, prepaid meter), GPRS or CDMA modules. Lightning protection function: The box machine is equipped with lightning protection module, but the control box must be reliably grounded. Valve adjustment function 1: In manual mode, after inserting the equipment card, the valve opening can be adjusted through the keyboard. In automatic mode, Method: After recharging, the valve will automatically and slowly open. Equipped with remote control mode, the valve opening can be adjusted through the upper computer.

　　Qingdao Hesheng CompanyDistributed heating network management system, smart heating network for power plants, saturated steam energy charging softwareAdvantage:

　　1. On site operation data 4G real-time upload: 4G wireless communication terminals are responsible for the important task of data transmission, and can upload on-site data to the heating network service center in real time to track and monitor the thermal parameters (pressure, temperature, flow rate, etc.) of the heating network, and grasp the heating status of the entire heating network management line. 2. Flexible networking and rapid deployment: Wireless networking mode has the characteristics of flexible networking, high data transmission rate, wide signal coverage, strong real-time performance, high security, low operating cost, and low maintenance cost; Suitable for situations where equipment is widely distributed and it is inconvenient to install network cables, wireless networking can achieve data transmission without geographical limitations as long as the operator's network coverage is available, shortening the project deployment cycle. 3. Fault diagnosis and analysis, timely fault reminder: on-site collection and measurement instrument failures can also be detected in a short period of time, and the fault time can be recorded and filed to avoid measurement losses and eliminate the idea of users stealing steam. In case of power outages or abnormal collection parameters at the hot user end, information can be timely predicted and personnel can be reminded to handle them through platforms or methods. 4. Remote operation and maintenance management, reducing operation and maintenance costs: Management personnel can see the steam usage of users in various places in the management background, without the need for on-site manual meter reading. Fault report information is convenient for maintenance personnel to check and repair in a timely manner, reducing and saving a lot of manpower and material resources

　　5. IC card prepaid management overdraft function: You can choose the "overdraft" function, which allows individual special users to have a certain overdraft limit. 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 RS485 wired data remote meter reading system uses a combination of computer technology, modern communication technology, network technology, and microelectronics technology. It is mainly a meter reading method that collects data through remote intelligent terminals and transmits the data to a specific system through wired networks, and completes other forms of operation in the system. The heating network center also has a series of functions such as remote control of valves and remote recharge
