Description :

Qingdao Hesheng Zhiyuan Automation System Co., LtdPrepaid intelligent control system, intelligent thermal testing, wireless remote transmission prepaid protocolTechnical specifications for measuring instrument stations: The measuring station is installed in the factory of the steam unit, with one set per unit, including intelligent flow integrator, 4G module, antenna, data cable, unboxing equipment, DC backup power supply (UPS), wall mounted instrument box, and power distribution system. All devices should have replaceability and universality. The above devices need to be integrated into one chassis, and the connections between devices have been integrated and debugged as a whole before leaving the factory; Protection level IP65. Adopt protective measures such as pressure-sensitive and TVS to deal with and solve potential accidents such as voltage fluctuations, vibrations, electromagnetics, and lightning strikes in the power grid.

　　Qingdao Zhiyuan InstrumentPrepaid intelligent control systemFunction Introduction:

　　1. Dynamic display of valve status, unboxing status, instantaneous flow rate, pressure, temperature, cumulative flow rate, etc. for each hot user, with different colors used to represent different statuses; When each user point is in normal state, it is displayed in blue. When the parameters exceed the limit, it is reported, or there is a fault, it is displayed in red and flashes, and information is synchronously sent to notify personnel; 2. Real time historical data and curves of flow rate, pressure, temperature, density, differential pressure, and frequency are displayed in the same coordinate system, and can be freely compared. The mouse follows and displays the current data, which is intuitive and easy to analyze; 3. Smart heating information management can directly add heating customers through the front-end webpage, with convenient and fast operation, sorted by number, and the order of customer arrangement can be freely adjusted; Provide detailed information on thermal units, establish maintenance information for measuring equipment, and facilitate management personnel to query the history and current status of instruments; 4. Automatically generate daily, monthly, annual, and report forms, and be able to print reports in real time. Reports can be made according to the requirements of the thermal company. 5. Thermal user management data system, including flow rate, pressure, temperature, upper and lower limit report settings, instrument current operating parameters, unit price, special policies, responsible person information, etc., to prevent users from modifying settings; 6. Multi level operation permissions for GPRS meter reading and metering terminals are set and controlled by administrators to prevent unauthorized operations by personnel at different levels;

　　Qingdao Hesheng CompanyPrepaid intelligent control system, intelligent thermal testing, wireless remote transmission prepaid protocolAdvantage:

　　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. The cloud platform steam prepaid system has a debugging function. In the debugging state, the valve can be opened without recharging. The above functions can be enabled or disabled through the function menu of the controller. Facilitate the coordination and management of heat user loads. The balance of the gas bill is insufficient. After reaching the set value for stopping the gas, the electric valve will automatically close and send a signal

　　Qingdao Zhiyuan InstrumentPrepaid intelligent control systemMain 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. Prepaid intelligent control system, intelligent thermal measurement, wireless remote transmission of prepaid protocol system to transmit recharge records, instantaneous flow, cumulative flow, pressure, temperature, differential pressure, frequency, power outage frequency, power outage cumulative, remaining amount, valve opening, instrument box status, power supply status, etc. It also has remote recharge, valve control adopts simulated output control mode or switch control mode, one meter, one card, cannot be exchanged, system security, remote meter reading system software to the site. Instrument transmission commands enable data from various instruments to be transmitted through RS-485 The interface is transmitted to the corresponding data acquisition module, which automatically reads various data information from each meter according to the meter reading task issued by the management center, such as pressure, temperature, flow rate, power outage information, hour, day, month data, etc. The permissions of the sub center are limited to data monitoring and are not allowed to operate downwards. For the security of the system, the data of each sub center in the main center is fully synchronized and displayed in real time
