Smart heating management system, steam metering terminal, heating wireless meter reading terminal

Description :

　　Qingdao Zhiyuan Instrument Prepaid Calculator complies with the JJG1003-2016 standard and meets the trade settlement requirements of the new metering regulations for integrated calculators.

　　A. Instrument model EF-II/TCP, LCD display screen.

　　B. The instrument has an accuracy of ± 0.2% and is capable of outputting 4-20mA analog signal current (output category can be freely defined).

　　C. The function of intelligent accumulation instrument is to measure pressure, temperature, instantaneous flow rate, cumulative flow rate, frequency, differential pressure, steam balance, power outage frequency, power outage and incoming call time, daily cumulative monthly cumulative query, etc. It is programmable and can set parameters according to actual needs;

　　D. Multiple cumulative methods (lower limit flow, over flow), cumulative coefficient (percentage) can be set. It can be set that when the flow rate is less than a certain percentage of the range (such as 10%), the lower limit flow rate will be accumulated according to this fixed value. It can also be set that when the flow rate is greater than a certain percentage of the range (such as 110%), the excess flow rate will be accumulated according to the set multiplier, thus solving the problem of low flow rate in small flow and excess flow measurement and meeting the actual needs of heat network calculation.

　　Qingdao Hesheng Zhiyuan Automation System Co., LtdSmart Heating Management SystemSystem 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. Open 100 remote metering points for online monitoring of the thermal pipeline network, with N metering points used in the first phase and the excess 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. If the smart heating network valve control site has a gas flow meter, it is not necessary to use our flow integrator. Only the on-site flow meter needs to have RS485 communication function. Based on the communication protocol of the meter, we have developed communication software and directly connected it to the IC card control instrument through RS485 line. Curve analysis: It can achieve numerical comparison of pressure, temperature, and instantaneous flow of each instrument in different time periods. Furthermore, obtain their fluctuation situation, clarify the reasons for their fluctuations, in order to formulate corresponding measures

Smart heating management system, steam metering terminal, heating wireless meter reading terminalA remote meter reading system based on low-power Internet of Things, comprising a terminal meter reading node, a centralized procurement node, a cloud server, a centralized meter reading management platform, and user terminals. The terminal meter reading node of the intelligent heating management system collects user meter data, sends the data packet to the centralized acquisition node, the centralized acquisition node and the terminal meter reading node establish a one to many communication mode, and wirelessly transmits the data collected by multiple terminal meter reading nodes to the cloud server. The centralized reading management platform connects the cloud server through the Internet, processes the data collected by the terminal meter reading node, and sends instructions according to the status of the terminal meter reading node. The terminal meter reading node sets a wake-up mechanism, receives instructions, and controls the data acquisition module and communication module responses through its main control module. Users can receive payment reminders and view water/electricity/gas/heat information based on the user terminal. Curve analysis: It can compare the pressure, temperature, and instantaneous flow values of each instrument over different time periods. Furthermore, their fluctuation situation can be obtained, and the reasons for their fluctuations can be clarified in order to formulate corresponding measures. Currently, the main operating parameters and equipment operations in the factory production process can be collected and managed through a distributed system. After the system is established, the value reading time of the meter is unified, changing the original 15-30 minutes of manual reading, achieving fairness in assessment while reducing the labor intensity of personnel, reasonably allocating resources such as personnel, finance, and materials, improving efficiency, and realizing economic benefits

　　At present, most heating companies supply steam first and then settle monthly when selling steam, but this may result in some user units defaulting on steam payments, causing inconvenience to heating companies. The steam IC card prepayment control system developed by Qingdao Hesheng Company can effectively eliminate the above-mentioned problems. The steam users of this system must pay in advance and recharge before opening the valve to use steam. They must also renew and recharge before the balance is exhausted. When the balance is insufficient, local and remote notifications will be sent to remind users to pay in a timely manner. If the balance is not renewed in time, the system will automatically close the valve and stop steam when the balance is zero, eliminating the phenomenon of overdue payment by the steam users. combineSmart Heating Management SystemReal time customer gas usage status, the system control box has unboxing and disconnection reports. Once a customer opens the metering box or system control box without authorization, the data will be immediately transmitted to the control center to remind the staff of the time, and the electric valve will be remotely controlled to close and stop the steam supply, which will have a deterrent effect on malicious behavior by users.
