1. Program overview

As the scale of production increases, the area of ​​the site continues to increase. The safety risks of the factory, the environmental quality of the workshop and the smooth operation of the factory facilities are the keys to ensuring continuous production. The smart factory digital platform should be able to comprehensively monitor the key indicators of the factory, give early warning and Linkage, intuitively displays the real-time operating status of the plant's on-site hazards, environment and plant affairs, realizes self-detection, self-defense, and has a configurable digital system for security environment situation awareness.

2. Program highlights

Independent and configurable: adopting a completely independent and controllable localization plan, based on a fully-configured platform development, and enabling online production line layout and other configurations, with flexible management and reducing repeated project investment;

Comprehensive perception: Each part of the data link is opened, the access protocol is unified, and the overall data access and global time-space perception are realized;

Self-defense: closed-loop early warning and alarm management, automatic update and maintenance of the knowledge base, to realize self-detection and defense.

3. system architecture

1) Data collection layer

Realize data sharing and application integration between different application subsystems and different device interface protocols, with a distributed architecture to ensure stability and scalability.

2) Platform layer

BS architecture system, with integrated operation management, data analysis and processing, module component library, centralized development and remote deployment capabilities. Provide background service support for the system to ensure stable operation of the system.

3) Presentation layer

Realize cross-platform display, visual space switching, model and data linkage, and improve users' understanding of operations and overall business.

4.1 Cockpit

As a management visualization solution, the management cockpit allows corporate managers to intuitively monitor corporate operations, as well as early warning and mining analysis of abnormal key indicators, just like the dashboard in the cockpit of an airplane or car. The management cockpit is intuitive, comprehensive, convenient, multi-dimensional and configurable, which can greatly assist enterprise managers to understand relevant decision-making information, grasp the main problems and main aspects of the problem, and early warning of potential problems, thereby To enable enterprises to better achieve business and management objectives.

According to different management rights, you can configure customized cockpit content to comprehensively view the park safety, operating parameters and energy consumption.

4.2 An all-Management

Monitor the status of various hazard sources (smoke, temperature, current fire, combustible gas, acid mist, liquid leakage, formaldehyde, etc.) and high-risk equipment in the plant area, combined with the panoramic view of the plant area, real-time monitoring of the hazard source status, and view the hazard source warning Status, current monitoring values, warning limits and historical records.

Dangerous sources are monitored by classification and classification, and can be configured online. When an early warning occurs, you can jump to remind you in the overview map, click on the hazard source logo to enter the local area display screen. Severe alarms are automatically popped up, and video and equipment are linked to take emergency measures.

4.3 Environmental Management

Combined with AGV trolley and on-site sensors, real-time monitoring of various environmental parameters (cleanliness, temperature and humidity, noise, lighting, etc.), and through three-dimensional graphical display, can automatically calculate the regional difference. The inspection route and production line support online configuration to meet flexible production requirements.

4.4 Power System

The power supply and distribution system is the lifeblood of the park, so the monitoring and management of the power supply and distribution equipment is very important. This solution monitors the operating status of the circuit breakers or contactors in the power supply and distribution in real time, and uses different monitoring interfaces on the monitoring interface. The icons and colors indicate the operating status of connected, disconnected, short-circuit or overload faults, and contain sound alarms and text prompts to facilitate the on-duty personnel to deal with faults in time.

4.5 HVAC system

Mainly for centralized central air-conditioning system. The air-conditioning system consists of fresh air, return air, filters, cooling and heating coils, blowers, air conditioning units, etc. The main monitoring content of air conditioning units: air supply volume, return air volume, fresh air volume, delivery Air temperature, supply air humidity, start and stop of blower, return blower, air purifier, etc.

4.6 Pneumatic system

Combined with the air pressure process chart, the air pressure data is monitored in real time, and the space switching list is provided. Monitor data such as pressure, temperature, flow, dew point and loading status, and automatically alarm when abnormalities occur, and switch backup plans.

4.7 Alarm management

The system records the alarm information of each subsystem, and the historical alarm is stored in the database for query use. The operator can confirm, mute, and clear the real-time alarm information. When the alarm point returns to the normal state, the system will automatically restore the alarm system and display it as an alarm recovery state. The alarm information is classified as follows:

1. Equipment automatic control system: mechanical and electrical equipment failure alarm, controller failure alarm.

2. Fire alarm system: failure alarm of fire host and failure alarm of fire broadcast.

3. Closed-circuit television monitoring system: host failure alarm, pan-tilt controller failure alarm, video image failure alarm;

4. Anti-theft alarm system: alarm of anti-theft probe and fault alarm of controller.

4.8 Knowledge Base Management

Equipped with knowledge base management of the plan, automatically matching the plan after an alarm occurs, and guiding on-site disposal. At the same time, according to the on-site disposal situation, the plan can be re-improved and updated and optimized continuously.
