Description :

Qingdao Zhiyuan InstrumentWireless data acquisition 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.

Wireless Data Collection System, GPRS Recharge Management, Hot Water Meter Reading System SpecificationBasic function: 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 tables correspond one-to-one and cannot be interchanged. If the password verification fails three times in a row, the IC card will be locked and cannot be used for data writing operations. The data transmission of high-level networks adopts fiber optic transmission with good compatibility, high reliability, fast data transmission speed, and long transmission distance

　　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.Wireless data acquisition systemOverdraft function: You can choose the "Overdraft" function. For individual special users, they are allowed to have a certain amount of 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 IC card prepaid system consists of a prepaid control box; Explosion proof (explosion-proof) electric control valve; Card reader/writer (including recharge software); Items 1, 2, and 3 are installed at the on-site measurement point, while item 3 is installed on the office computer of the management personnel. Curve analysis: It can compare the values of pressure, temperature, and instantaneous flow of each instrument at 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. The management center software has functions such as querying and displaying the remaining gas volume of gas units, and reporting insufficient remaining gas volume. Real time monitoring and display of user data electronic map (flow rate, pilot valve status, etc.), IC card prepaid flowmeter with RS485 communication, realizing remote data transmission and valve adjustment function

　　Qingdao Hesheng Zhiyuan Automation System Co., LtdWireless data acquisition systemIntelligent report 1. It can automatically generate daily reports, monthly reports, annual reports, and reports, and can print reports in real time. 2. It can query historical data reports for any hot user, any parameter, and any time period, and supports exporting statistical reports and analysis curves. 3. It can print daily, monthly, and detailed reports on gas consumption for each individual user and all users, as well as contemporaneous and annual reports, and can be archived as Excel files (*. xls). 4. The report format can be created according to the requirements of the bidding party, and the system needs to have monthly automatic settlement function to generate electricity meters. 5. The steam IC card prepaid APP GPRS wireless network provides a simple and effective communication transmission method for heating systems. 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 the existing network, shortening the construction period, and reducing construction costs. Moreover, the equipment is easy to install and maintain. In the management room, the network browsing function can provide a clear view of the entire system, enabling 24-hour operation of the heating network. All physical quantity data in the system is displayed on the screen, informing users of steam parameters and pipeline operating parameters. In the event of a malfunction, it can be easily accessed*

　　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.
