Description

Technical Field

[0001] The present invention relates to the technical field of monitoring systems, and in particular to a DDC integrated monitoring system based on a unified application support platform. Background Art

[0002] The DDC controller is a communication protocol and controller for display devices. It is based on the I2C communication protocol and communicates with the display device through the I2C bus to monitor the display device. This controller defines the specifications for two-way communication between the computer and the display, allowing the computer to send commands and requests through the display's connection interface (such as VGA, DVI, HDMI, etc.) to obtain information about the display and perform corresponding control.

[0003] DDC controllers are commonly used in monitoring systems. The monitoring backend serves as the daily operational interface for process control system users. Its ease of use, responsiveness, and stability largely determine user reputation. When backend function development and maintenance are separate software systems from controller development and maintenance, a communication configuration text interface is suitable for typical applications. However, industrial control requires extensive on-site debugging. Improving efficiency requires reducing user judgment and intervention, providing users with a system perspective, and leveraging classification, hierarchical management, guidance, and real-time prompts to help them complete projects. Existing technologies struggle to meet these requirements. Traditional DDC monitoring systems have low integration levels and typically manage different monitoring modules (such as automatic fire alarm systems and environmental and equipment monitoring systems) in a decentralized manner. The lack of a unified monitoring platform and application support platform makes data exchange and communication between system modules difficult, making comprehensive and efficient real-time monitoring and management impossible. Therefore, the present invention proposes a DDC integrated monitoring system based on a unified application support platform to address the problems of the existing technology. Summary of the Invention

[0004] In response to the above problems, the present invention proposes a DDC comprehensive monitoring system based on a unified application support platform. The DDC comprehensive monitoring system based on a unified application support platform facilitates unified management, makes data interaction and communication more convenient, and realizes comprehensive monitoring and overall perception of the system.

[0005] To achieve the objectives of the present invention, the present invention is implemented through the following technical solutions: a DDC integrated monitoring system based on a unified application support platform, including a DDC controller and a system hardware architecture and a system software architecture based on the DDC controller, wherein the system hardware architecture includes a data interface layer, a data processing layer, and a human-machine interface layer, and the system software architecture includes functional modules and monitoring modules, wherein the monitoring modules include an automatic fire alarm system, an environment and equipment monitoring system, an access control system, a closed-circuit television system, a broadcasting system, a personnel positioning system, and a clock system, and the functional modules include a human-machine interface, an alarm module, and a permission management module;

[0006] The human-machine interface layer is a graphical interface for human-machine interaction, and monitoring data is exchanged between the human-machine interface layer and the operator. The data interface layer is used to connect all monitoring sensors and exchange data. The data processing layer is used to centrally collect and process the interaction data of the data interface layer and the human-machine interface layer and input it into the system software architecture. The system software architecture is used to subdivide the data into different unit systems in the monitoring module and display the data in a unified manner on the human-machine interface. The alarm module is used to issue an alarm when the monitoring data is abnormal.

[0007] A further improvement is that the data processing layer consists of a regional server and a central server. The regional server is used to process and collect data in a specified area, centralize and process the data for display and operation on the human-machine interface of the area, and the central server is used to centralize and process data in the entire range of all areas for display and operation on the human-machine interface of the control center.

[0008] Further improvements are: the human-machine interface layer is a graphical interface for human-machine interaction, through which equipment status information, operation information, fault information, alarm information, and statistical report information are displayed to the operator. The operator monitors, sets, and controls remote equipment on the workstation based on the human-machine interface layer, and divides personnel responsibilities and the scope of monitoring and jurisdiction of equipment through authority and responsibility areas.

[0009] Further improvements include: the DDC controller is connected to the data interface layer, and the operating status, energy consumption and device parameter information of various devices are collected in real time through monitoring sensors. The DDC controller is equipped with a configuration tool, including the IEC61131-3 standard configuration language, which is used to customize data structures and functional modules and match the control logic of different sites and different devices for data collection.

[0010] Further improvements are: the system software architecture relies on a unified application support platform, including distributed real-time database management, historical data management, human-computer interaction, network message transmission, system management, and alarm service functions, and establishes a comprehensive monitoring system panoramic model to integrate and interconnect the various unit systems in the monitoring module. The comprehensive monitoring system panoramic model is based on SOA architecture cross-hardware platform system integration and panoramic view technology.

[0011] Further improvements are: the system software framework is used for object-oriented real-time database modeling, unified data display, and unified system management, integrating the automatic fire alarm system, environment and equipment monitoring system, access control system, closed-circuit television system, broadcasting system, personnel positioning system, and clock system to carry out business integration and information integration.

[0012] Further improvements are as follows: the human-machine interface is used to provide an HMI screen, and the operator performs monitoring functions, remote control and remote adjustment operations on the HMI screen, and monitors each unit system in the monitoring module through the human-machine interface. The HMI screen layout includes: a menu bar: for customized operations; a navigation area: for displaying the currently controlled unit system; a monitoring area: for displaying the screens of each unit system and monitoring the equipment status; a function area: for customizing the display of user information, login node information, time, alarm, screen switching, printing, and forward and backward functions.

[0013] Further improvements are: the alarm module is used to provide an alarm function. When the status of the equipment or point reaches the state predefined by the alarm rules, the integrated monitoring system will automatically generate an alarm and notify the operating personnel through the HMI screen. The alarm is displayed in different levels with different colors according to the severity of the event. Each alarm level is associated with a different sound of the operator station speaker, and the corresponding alarm entry is automatically displayed according to the operator's authority.

[0014] Further improvements are: the alarm categories of the alarm module include unit switch position change alarm, double-position switch quantity alarm, analog quantity over-limit alarm, equipment failure alarm, network communication failure alarm, and control operation alarm; the alarm modes of the alarm module include: function area alarm bar, important alarm table and event table, sound alarm, image alarm and text alarm.

[0015] A further improvement is that the authority management module is used to configure a user name and a predefined user password for each qualified operator, log in and enter the system through the user name and predefined user password, and simultaneously assign an approved user mode. After successfully logging into the system, different interfaces and operating functions are opened according to the authority of the logged-in user. The authority levels are divided into three categories: system management level, operation level and browsing level.

[0016] The beneficial effects of the present invention are:

[0017] 1. The present invention is based on a DDC controller. Through the human-machine interface layer, data interface layer, and data processing layer, it accesses the data of all monitoring sensors, centrally collects and processes them, conducts monitoring interaction with operators, and inputs them into the system software architecture. It subdivides the data into different unit systems in the monitoring module and presents unified data on the human-machine interface.

[0018] 2. The present invention realizes layer-by-layer progressive processing of data in designated areas and all areas through the functional allocation of servers and central servers at the data processing layer, and cooperates with the operator responsibility division function at the human-machine interface layer to make the system comprehensive and sophisticated.

[0019] 3. In the data processing layer of the present invention, the regional server is used to process and collect data in the designated area for display and operation on the human-machine interface of the area. The central server is used to concentrate and process data of all areas and ranges for display and operation on the human-machine interface of the control center. The human-machine interface layer displays various information to the operator. The operator monitors, sets and controls the remote equipment on the workstation based on the connection of the human-machine interface layer. This is beneficial from the perspective of decoupling, separating the interfaces and functions that are directly connected to the user and handing them over to the application department for maintenance. At the same time, the mature components of the monitoring background are reused to the greatest extent possible, thereby improving efficiency, ensuring safety and controllability, and facilitating more direct and efficient service to customers and improving product performance.

[0022] In order to deepen the understanding of the present invention, the present invention will be further described in detail below with reference to the examples. The examples are only used to explain the present invention and do not constitute a limitation on the scope of protection of the present invention.

[0023] Example 1

[0024] according to Figure 1 、 2As shown, this embodiment proposes a DDC integrated monitoring system based on a unified application support platform, including a DDC controller and a system hardware architecture and system software architecture based on the DDC controller. The system hardware architecture includes a data interface layer, a data processing layer, and a human-machine interface layer. The system software architecture includes functional modules and monitoring modules. The monitoring modules include an automatic fire alarm system, an environment and equipment monitoring system, an access control system, a closed-circuit television system, a broadcasting system, a personnel positioning system, and a clock system. The functional modules include a human-machine interface, an alarm module, and a permission management module.

[0025] The human-machine interface layer is a graphical interface for human-machine interaction. Monitoring data is exchanged between the human-machine interface layer and the operator. The data interface layer is used to connect all monitoring sensors and exchange data. The data processing layer is used to centrally collect and process the interaction data between the data interface layer and the human-machine interface layer and input it into the system software architecture. The system software architecture is used to subdivide the data into different unit systems in the monitoring module and display the data in a unified manner on the human-machine interface. The alarm module is used to alarm when the monitoring data is abnormal. When in use, based on the DDC controller core, through the human-machine interface layer, data interface layer, and data processing layer, data from all monitoring sensors are accessed, centrally collected and processed, and monitoring interaction is carried out between the human-machine interface layer and the operator, and input into the system software architecture. The data is subdivided into different unit systems in the monitoring module and displayed in a unified manner on the human-machine interface. It covers multiple systems such as automatic fire alarm, environment and equipment monitoring, access control, closed-circuit television, broadcasting, personnel positioning, clocks, etc., which facilitates unified management, makes data interaction and communication more convenient, and realizes comprehensive monitoring and overall perception of the system. The connection structure of fire alarm system (FAS), environment and equipment monitoring system (BAS), access control system (ACS), closed circuit television system (CCTV), broadcasting system (PA), personnel positioning system, and clock system (CLK) is shown in Figure 1 .

[0026] The data processing layer is composed of regional servers and central servers. Regional servers process and collect data for a specific region, centralizing and processing the data for display and operation on the human-machine interface of that region. Central servers centralize and process data from all regions for display and operation on the human-machine interface of the control center. The data processing layer primarily consists of regional servers and central servers. Regional servers perform secondary data processing and collection, centralizing and processing data for display and operation on the human-machine interface of the monitoring system, collecting data within their respective regions. Central servers, in addition to processing and collecting data for their own regions, also perform tertiary data centralization and processing for display and operation on the human-machine interface of the control center, collecting data from the entire region.

[0027] The human-machine interface layer is a graphical interface for human-machine interaction, through which the operator is displayed equipment status information, operation information, fault information, alarm information, and statistical report information. The operator monitors, sets, and controls remote equipment on the workstation based on the connection of the human-machine interface layer, and limits the division of personnel responsibilities and the scope of monitoring and control of equipment through authority and responsibility areas. The human-machine interface layer is a graphical interface for human-machine interaction provided by the integrated monitoring system. The integrated monitoring system can display equipment status information, operation information, fault information, alarm information, statistical report information, etc. to the operator through this interface. At the same time, the operator can monitor, set, and control remote equipment on the operator workstation with the help of a series of tools provided by the system. The human-machine interface layer is mainly reflected in various user workstations, deployed in and centers, and limits the division of personnel responsibilities and the scope of monitoring and control of equipment through authority and responsibility areas.

[0028] The DDC controller accesses the data interface layer and uses monitoring sensors to collect real-time information on the operating status, energy consumption, and device parameters of various devices. The DDC controller's accompanying configuration tool, including the IEC61131-3 standard configuration language, allows for customizing data structures and function modules to match data collection with the control logic of different sites and devices. The DDC supporting configuration tool supports the IEC61131-3 standard configuration language, allowing for customizable data structures and function modules, providing high flexibility and adaptability to the control logic of different sites and devices. The configuration language, or functional interface, is described as follows: Programming Language - FBD: Function Block Diagram, which connects various function blocks to achieve the desired control function. It is a graphical, high-level programming language, similar to an electronic circuit diagram, using graphical I / O connection lines to assign input and output signals and determine data flow. Programming Language - LD: Ladder Diagram, inspired by relay control circuits, is a simplified version of commonly used relay and contactor logic control symbols. Ladder diagrams are visually appealing, intuitive, and practical, making them easily accepted by electrical technicians. Programming language - ST: Structured file, similar to PASCAL and C language, uses text-type high-level language programming to implement complex logical calculations and function implementation (such as for loops, etc.). The DDC supporting configuration tool supports incremental update mode to achieve non-disruptive update of the configuration, which can minimize the impact of configuration changes on equipment operation during debugging and operation. The DDC supporting configuration tool supports offline / online hardware configuration, software configuration, logic simulation and operation debugging of controllers and IO, which is convenient for debugging and easy to use. It supports output fail-safe state. AO and DO modules can maintain fail-safe by setting safety mode and safety value in the configuration tool, reducing the impact of occasional failures on on-site operating equipment and improving the reliability and stability of the system.

[0029] The system's software architecture relies on a unified application support platform, encompassing distributed real-time database management, historical data management, human-computer interaction, network messaging, system management, and alarm services. It also establishes a comprehensive monitoring system panorama model, integrating and interconnecting the various unit systems within the monitoring modules. This panorama model leverages SOA architecture for cross-hardware platform system integration and panoramic view technology. The system utilizes a modular design, allowing users to select modules and combine them into applications as needed. Comprehensive applications can be built in phases, and the integrated platform facilitates tight integration of subsystems, providing technical support for comprehensive monitoring business and information integration.

[0030] The system software framework is used for object-oriented real-time database modeling, unified data display, and unified system management. It integrates the automatic fire alarm system, environment and equipment monitoring system, access control system, closed-circuit television system, broadcasting system, personnel positioning system, and clock system to carry out business integration and information integration.

[0031] The human-machine interface (HMI) provides an HMI screen, allowing operators to perform monitoring, remote control, and remote adjustment operations on the HMI screen. The HMI screen layout includes a menu bar for customizable operations; a navigation area for displaying the currently controlled unit system; a monitoring area for displaying individual unit system screens and monitoring device status; and a function area for customizing user information, logged-in node information, time, alarms, screen switching, printing, and forward and backward functions. Operators can perform basic monitoring, remote control, and remote adjustment operations on the HMI screen. In the control center, each operator's workstation utilizes a unified and user-friendly graphical user interface (GUI), enabling operators to more conveniently and efficiently monitor the various subsystems of the integrated monitoring system. The GUIs on each workstation adopt a consistent style, with standardized display layout, graphical representation, and color definitions. Login controls ensure operational authority and security. Control commands can be entered using either the mouse or keyboard. While mouse operation is generally the primary method, shortcut keys can be assigned to frequently used commands and key operations to provide a quick alternative.

[0032] The alarm module is used to provide an alarm function. When the status of a device or point reaches the state predefined by the alarm rules, the integrated monitoring system will automatically generate an alarm and notify the operator through the HMI screen. The alarm is displayed in different levels with different colors according to the severity of the event. Each alarm level is associated with a different sound from the operator station speaker. The corresponding alarm entry is automatically displayed according to the operator's authority.

[0033] Alarm color definition

[0034] Alarm level Alarm name Display Color content Level 0 event green Alarm Events Level 1 Priority 4 blue Four-level alarm Level 2 Priority 3 yellow Three-level alarm Level 3 Priority 2 orange color Secondary alarm Level 4 Priority 1 red Level 1 alarm

[0035] The alarm categories of the alarm module include single-position switch change alarm, double-position switch alarm, analog over-limit alarm, equipment failure alarm, network communication failure alarm, and control operation alarm. The alarm modes of the alarm module include: function area alarm bar, important alarm table and event table, sound alarm, image alarm and text alarm.

[0036] The permissions management module assigns each qualified operator a username and predefined password. Each operator then logs into the system using this username and password, and is assigned a recognized user profile. After successful login, different interfaces and operational functions are available based on the logged-in user's permissions. Permission levels are categorized into three main levels: system management, operational, and browsing. To provide authorized login access, operators must first log in with a valid username and password. The system then assigns them a recognized user profile, known as a "user category," before allowing them access to system functions.

[0037] The user class defines the permissions of the logged-in user, which determines the user's read, write, control and alarm confirmation permissions for the application and data areas.

[0038] Read: The user has the right to observe objects in this area (such as a sensor value, device status, or alarm).

[0039] Write: The user has the right to update the object properties of the region (such as setting a flag on a data point).

[0040] Control: The user has the authority to issue commands to objects in the area (such as closing a circuit breaker).

[0041] Alarm confirmation: The user has the right to confirm and delete alarms from objects in this area.

[0042] After a user successfully logs into the system, the workstation opens different interfaces and operating functions based on the logged-in user's permissions. At this point, the user can perform corresponding operations according to the authorization, execute the monitoring and control of related equipment, and effectively prevent unauthorized operations.

[0043] Example 2

[0044] according to Figure 1 、 2 As shown, this embodiment proposes a DDC integrated monitoring system based on a unified application support platform, including a DDC controller.

[0045] The main parameters of the DDC controller are shown in the following table:

[0047]

[0048] The main parameters of the IO module are shown in the following table:

[0049] Main parameters of DDC supporting IO module

[0050]

[0051] The DDC performance indicators meet the technical requirements of GB / T15969.1-2007, GB / T15969.2-2008, GB / T15969.3-2017, GB / T15969.4-2007, GB / T15969.5-2002, GB / T15969.6-2015, GB / T15969.7-2008, GB / T15969.8-2007 and other standards.

[0052] Based on the complementary technology of discrete devices and integrated circuits, software-enhanced error detection and recovery technology, through multi-point compensation, power frequency multiplication sampling, and combined device complementation, the software adds error detection and correction mechanisms to ensure that the controller and I / O modules can operate stably for a long time in the complex environment of the project site. Accuracy tests were conducted on the analog input AI module and analog output AO module at 25°C:

[0054]

[0055]

[0056] The accuracy of AI and AO modules is higher than 0.1% of the full range, meeting the technical index requirements.

[0057] In addition, to improve the reliability of DDC and correct memory bit error flips caused by factors such as radiation, the CPU has locked in the selection of storage devices with ECC (memory error checking and correction technology) function during the selection process.

[0058] This DDC integrated monitoring system, based on a unified application support platform, utilizes a DDC controller. Through the human-machine interface layer, data interface layer, and data processing layer, it accesses data from all monitoring sensors, centrally collects and processes it, interacts with operators, and inputs it into the system software architecture. This data is then subdivided into different unit systems within the monitoring module, and presented uniformly through the human-machine interface. This system encompasses multiple systems, including automatic fire alarms, environmental and equipment monitoring, access control, closed-circuit television, broadcasting, personnel location, and clocks, facilitating unified management and making data interaction and communication more convenient, enabling comprehensive monitoring and overall perception of the system. Furthermore, through the functional allocation of servers and central servers in the data processing layer, the present invention enables layer-by-layer progressive processing of data across the entire range of designated areas and all regions. This, combined with the operator responsibility division function of the human-machine interface layer, makes the system comprehensive and sophisticated. At the same time, in the data processing layer, the server is used to process and collect data in the specified area for human-machine interface display and operation in the area. The central server is used to concentrate and process data in all areas and ranges for human-machine interface display and operation in the control center. The human-machine interface layer displays various information to the operator. The operator monitors, sets and controls the remote equipment on the workstation based on the connection of the human-machine interface layer. From the perspective of decoupling, it is beneficial to separate the interfaces and functions that directly connect to the user and hand them over to the application department for maintenance. At the same time, it reuses the mature components of the monitoring background to the greatest extent possible, improves efficiency, is safe and controllable, and is convenient to serve customers more directly and efficiently, thereby improving product performance.
