Qingdao Zhiyuan InstrumentCentralized water supply 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 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.

Centralized water supply management system, heating wireless meter reading, IC card energy consumption management monitoringUpload valve position, flow rate and other data, and the upper computer can set the reporting method arbitrarily. Flexible communication parameter settings: The communication address and baud rate of the prepaid controller can be set as needed (address range: 1-128, baud rates: 2400, 4800, 9600). Communication function: Provides RS485 communication interface, which can be connected through wired, GPRS/CDMA, and other methods, using standard Modbus RTU protocol. At present, the values of various measuring devices are mostly manually reported by operators on a shift by shift basis. This simple and repetitive work inevitably brings some problems, such as unsynchronized meter reading, large human error, and high labor intensity. Manual meter reading has become an obstacle to the automation and informatization of data management in power plants. Therefore, the application of RS485 wired data remote meter reading system is necessary

　　1. On site training: During the implementation of the project, the client must assign technical personnel to participate in the construction and operation debugging of the project. Our company's engineering and technical personnel will provide on-site guidance and practical training for your company's personnel during implementation, ensuring that the progress of the project is synchronized with personnel training. Before the system trial run, we will provide system training to the customer. Through training, the customer's operational staff will understand the basic principles and learn system operation and maintenance, including a basic understanding of the software and hardware systems of this project. The training content is as follows: a. Basic knowledge and system configuration of the system, b. Courses on system installation, inspection, troubleshooting, online coordination and maintenance, and application training of human-machine interface. 2. Factory training: Our company conducts regular training for technical personnel of users who use our products every year. At that time, we will provide in-depth explanations of the company's software, hardware, and heating network technology, and conduct on-site practice according to the conditions. At the same time, we will answer any questions that users may have in various systems.

　　3Centralized water supply management systemReal time monitoring: It can achieve real-time data display function for multiple instruments. It is convenient to timely grasp the situation of each department's site, make corresponding adjustments and guidance, based on the GSM network, using packet switching transmission method to overcome the disadvantages of low conversion rate and poor resource utilization of GSM circuit, and make limited use of existing GSM network resources. It has a high transmission rate, short access time, and users are online in real time and charged based on traffic, quickly reducing service costs. It is particularly suitable for sudden small traffic data transmission

　　Heating metering is still more inclined towards smart heating, which is a direction and a development trend. Now heating metering has stepped on a key point in the development of the heating industry towards smart heating. It has virtually promoted the development of the industry. It has played a role in promoting the development of the heating industry through cloud computing measures such as big data, the Internet of Things, and the Internet.Centralized water supply management systemThe 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 step of manual operation. Therefore, with the help of this system, the cost of hot water and steam meters can be calculated. Valve adjustment function 2: over flow limit function, when the flow exceeds the set value, the valve opening will be automatically reduced. The small flow valve closing function automatically closes the valve when the flow rate remains below the set value for a period of time. The remote meter reading system software sends commands to the on-site instruments to transmit the data of each instrument to the corresponding data acquisition module through the RS-485 interface. The data acquisition module 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
