Qingdao Zhiyuan InstrumentCloud platform measurement management systemService commitment:

　　From the date of delivery of the heating network system, it enters the after-sales service period. The after-sales service period includes a free warranty period and a quality maintenance period.

　　Free warranty period: Within 12 months from the date of normal use of the product or system, it is a free warranty period. During the free warranty period, any quality issues within the warranty scope will be repaired and replaced by Party B free of charge.

　　Quality maintenance period: After the quality assurance period, we will continue to provide lifetime preferential services. The maintenance services carried out during the quality maintenance period will be charged material and labor costs based on the spare parts product price (not higher than the contract price) and maintenance situation set by the company.

　　The specific service items during the after-sales service period are as follows: receiving letters from users, providing responses or handling suggestions within 24 hours, and ensuring user satisfaction. And store the corresponding information in the user maintenance record sheet.

Cloud platform measurement management system, intelligent charging for automotive enterprises, and smart heating network designQuery and Statistics: Each instrument can be queried and displayed for data at any time during a certain period of time, making it easy to assess and query each shift. The wired data acquisition system is based on the RS485 bus. The RS485 wired data remote meter reading system is a system that uses modern communication and computer network technology to automatically read remote data

Cloud platform measurement management system, intelligent charging for automotive enterprises, and smart heating network designA 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 cloud platform metering 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 to receive instructions and control the data acquisition module and communication module response through its main control module. Users can receive payment reminders and view water/electricity/gas/heat information based on the user terminal. The traditional meter reading method is highly susceptible to factors such as weather conditions and errors or omissions in reading. However, the intelligent meter reading system directly eliminates the unstable link of manual operation. Therefore, with the help of this system, the cost of hot water and steam meters can be calculated. Therefore, gradually establishing a remote meter reading system for cities and using technological means to improve the measurement and management level of hot water, steam, tap water, gas, etc. has become a consensus among people. Moreover, the remote transmission distance can reach 1200 meters, which can reliably meet the needs of low-level data collection and transmission. At the same time, it also helps to reduce the distributed capacitance generated between two 485 communication lines and the distributed capacitance generated from around the communication lines

　　Qingdao Hesheng Zhiyuan Automation System Co., LtdCloud platform measurement management system, intelligent charging for automotive enterprises, and smart heating network designMeaning: In the context of vigorously building a smart city and promoting the development of "Internet plus" smart energy, the concept of smart heating came into being as an important branch of the energy industry. existingUrban Smart Heating Network SystemThere are still some issues during operation, such as insufficient remote points, relatively outdated control technology, high energy consumption, and low energy metering. Urban heating belongs to the main content of energy conservation and emission reduction. The development of contemporary heating systems must effectively combine traditional engineering with modern data science and technology, and improve the effectiveness of energy efficiency management by predicting the operation status of the heating network. The design of heating systems is often driven by demand, and predicting the demand for heat load on the consumer side plays a crucial role in improving the overall efficiency of the heating network operation.

　　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.
