GPRS wireless meter reading system, thermal power plant metering, hot water intelligent heating network solution

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.

　　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.

GPRS wireless meter reading system, thermal power plant metering, hot water intelligent heating network solutionThe 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 and displayed, including instantaneous flow rate, cumulative flow rate, remaining gas volume, differential pressure or frequency, pressure, temperature, valve position, etc. Prompt function: When the IC card is used incorrectly (when the IC card function does not match the operation being performed), the LCD screen displays a prompt message, and the operation is invalid

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. Basic functions of the comprehensive energy system in the industrial park: recharge first, then use gas, and automatically close the valve after use; Security: Three types of IC cards are used for management and operation, including equipment management card, user gas purchase card, and maintenance card; Cards and meters correspond one-to-one and cannot be interchanged. If the password verification fails three times in a row, the IC card will lock and cannot be used for data writing operations. The GPRS remote meter reading system has functions such as system maintenance, real-time monitoring, query statistics, curve analysis, etc. GPRS wireless network provides a simple and effective communication transmission method for the heating system. The GPRS system can provide wide area wireless IP connectivity. The wireless data transmission of on-site instrument data has the advantages of fully utilizing existing networks, shortening construction periods, and reducing construction costs. Additionally, the equipment is easy to install and maintain

GPRS wireless meter reading system, thermal power plant metering, hot water intelligent heating network solutionThe mobile data transmission network is a critical part of the system, connecting the past and the future, directly determining the operational effectiveness of the entire system. This part is built and maintained by mobile operators, ensuring reliability and stability, and users do not need to invest any additional funds. The mobile data transmission system of the smart energy management system connects the station and the center through GPRS/LTE communication modules and the Internet (static IP network cable) as a medium. The intelligent heating network management station packages various data and transmits it to the GPRS/LTE communication module through communication lines. The GPRS/LTE communication module encodes and processes the data, converts it into a format for public network data transmission, and sends it to the data network location of the mobile operator. The static IP extracts the data and finally transmits it to the central server.
