Wuhai Huatong Property is the largest property management company in Wuhai City. The company provides water supply services for industrial manufacturers and residential areas in Pinggou, Laoshidan, Huayuan and other areas. Our company (Beijing Juying Electronics) cooperated with the company and developed a water supply control system and a boiler operation monitoring system tailored for the company. Using our company’s RTU, the two systems were integrated into a large enterprise-level data management platform. , realizes the remote monitoring of all water supply equipment in the three areas under the enterprise, improves the automation of production operations, improves the reliability of system operation, and reduces human resources; realizes information management integrating measurement, measurement and alarm system.

1. System Features

The property management system has the characteristics of practicability, integration, scalability, advancement, professionalism, openness, security, and economy.

1. Practicality

It meets the requirements of the equipment under various operating conditions, ensures the safe, economical and stable operation of the unit, and is simple to operate, convenient and practical to maintain.

2. Economical

System construction should always implement the application-oriented, pragmatic policy, adhere to the principles of practicality and economy, and its economy should include the following:

1). The price of the system itself (including the system, technical services and training) is economical;

2). The system operating cost is economical;

3). The cost of implementing the system is economical;

4). The relevant expenses required for system integration are economical.

3. Advanced

Advanced and mature technologies are mainly used in system safe operation, personnel operation management, automatic control theory, field bus scheme, and later equipment maintenance.

There is an appropriate margin in the hardware configuration for future expansion of the system.

The monitoring and management system software has interfaces with enterprise production execution systems and other application systems based on middleware and OPC technology.

4. Professionalism

The whole set of testing system is highly professional, designed in strict accordance with the relevant national and professional standards, and fully considers the actual needs of the pump area and boiler room, so as to achieve the purpose of complete functions, optimized performance and advanced technology.

5. Security and Confidentiality

It mainly includes construction safety, operation safety, system and equipment safety, and data safety.

1), construction safety

Information such as daily work tasks, workflow, staffing, and safe use of incidental equipment will be issued.

2) Operational safety

Design specifications for the operation process, as well as system safety tips.

3), system-level device security

It mainly includes equipment installation safety, fault self-checking, and emergency measures safety. Taking into account the dangerous environment in the boiler room, all equipment is explosion-proof, and the alarm double backup redundant monitoring ensures production safety.

4), data security

In the system design, not only should the full sharing of information resources be considered, but also the protection and isolation of information should be paid attention to. Therefore, the system should take different measures for different applications and different communication environments, including system security mechanisms, data access and control measures. Permission control, etc.

6. Reliability

Implement strict quality management specifications in design, production, installation and commissioning, improve the anti-interference ability of the system, consider the security of mutual visits and access in the system, and ensure that the system has long-term stable working ability.

The system has an average trouble-free operating time of more than 10,000 hours.

2. Functions realized by the system:

1. Geographic information system (GIS) monitoring, which can mark the location of each well, pool, etc. on the map;

2. You can see each remote measurement and control terminal on the map, and read simple device information;

3. The central control room server and printer are configured nearby, with data storage and report printing functions;

4. Remotely monitor the working status of the pump, and can remotely control the start and stop of the pump;

5. When the liquid level of the reservoir exceeds the predetermined range, the local and central control room sound and light alarm;

6. The equipment has a self-checking function, and the equipment faults can be alarmed in time;

7. Be able to access the company’s local area network, and remotely view system information from any place in the company;

8. Monitor the operation of the boiler, including power consumption, water consumption, steam output, etc.;

9. Collect the working parameters of the return heat exchange station, including the temperature of the effluent and the return water, and the pressure of the effluent and the return water;

10. All instruments in the boiler room are explosion-proof;

11. Equipped with UPS backup power supply to supply the whole monitoring system with 2 hours of power supply.
