IC card prepaid metering box, heating enterprise card recharge, intelligent heating management design

Description :

　　Qingdao Hesheng Zhiyuan Automation System Co., LtdIC card prepaid metering boxEquipped with RS232/RS485 standard communication interface and MODBUS RTU, MODBUS ASC Ⅱ industrial standard communication protocol, it can communicate with intelligent flow meters, read various measurement parameters and working parameters in intelligent flow meters.

　　1. The device has automatic dialing and disconnection redialing functions. In case of unstable network conditions, it has the ability to automatically restore communication, and the system works stably without human intervention; When the signal in the area is weak, the module can communicate normally by changing the signal reception and transmission strength of the module.

　　2. Online query function can be achieved through the Internet, and users only need to provide their username and password. The real-time online query function can be completed.

　　3. Equipped with data cable and 12VDC power supply.IC card prepaid metering box, heating enterprise card recharge, intelligent heating management designBased on the GSM network, packet switching transmission method is adopted to overcome the disadvantages of low conversion rate and poor resource utilization of GSM circuits, and to maximize the utilization of existing GSM network resources. It has a high transmission rate, short access time, and users are online in real time and charged by traffic, quickly reducing service costs. It is particularly suitable for sudden small traffic data transmission. The permissions of the sub center are limited to data monitoring and do not allow downward operations, ensuring system security. The data of each sub center in the main center is fully synchronized and displayed in real-time

　　Distributed energy management system is relative to traditional centralized energy supply systems. Traditional centralized energy supply systems use large capacity equipment, centralized production, and then transmit various types of energy to numerous users over a large area through door transmission facilities (such as large power grids, large heat grids, etc.); Distributed energy systems, on the other hand, are small and medium-sized energy conversion and utilization systems that directly face users, produce and supply energy on-site according to their needs, have multiple functions, and can meet multiple objectives.IC card prepaid metering boxMoreover, the long-distance transmission distance can reach 1200 meters, which can reliably meet the needs of low-level data acquisition and transmission. At the same time, it also helps to reduce the distributed capacitance generated between the two 485 communication lines and the data generated from around the communication lines. Various meters transmit data to the on-site acquisition terminal through RS485 lines, and then transmit the data to the control room through independent and networked access to the system main station, avoiding external signals and network interference. The stability and security of data transmission are ensured. At the same time, it also has interfaces and redundancy with other networks

　　Qingdao Hesheng CompanyIC card prepaid metering box, heating enterprise card recharge, intelligent heating management designAdvantage:

　　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. Real time monitoring of steam prepayment system in the park: It can achieve real-time data display function for multiple instruments. Easy to timely grasp the situation of various department sites, make corresponding adjustments and guidance, lightning protection function: The box machine is equipped with lightning protection modules, but the control box must be reliably grounded. The composition of the IC card gas sales management system includes: main hardware such as IP network cables, servers, IC card readers, etc. The main software includes: operating system software, database software, heat network data IC card management system software, firewall software

　　Distributed energy systems, as energy supply centers serving the local area, directly face the needs of local users and are deployed near them. This simplifies the energy transmission process for users, reducing energy losses and transmission costs, and increasing the safety of energy supply for users. Due to its lack of large-scale and long-distance energy output mode, it mainly targets the energy needs of local users,IC card prepaid metering boxThe scale will be constrained by user demand, and compared to traditional centralized energy supply systems, it is of medium to small capacity. After the system was established, the unified reading time of meter values was achieved, changing the original 15-30 minute manual reading time, achieving fairness in assessment while reducing the labor intensity of personnel. Resources such as personnel, finance, and materials were reasonably allocated, improving efficiency and achieving economic benefits. The wireless remote intelligent meter reading system is built on the network of the GPRS data management center established within the enterprise, and all incoming traffic data is transmitted to the data center through a mobile GPRS network
