Description

Technical Field

[0001] The present invention belongs to the technical field of equipment monitoring, and in particular relates to an intelligent control system and a control method for a confidential exhibition hall. Background Art

[0002] The existing exhibition hall control system does not involve the intelligent control of confidential exhibition halls. This type of control system generally uses wired network or wireless network technology to connect the various equipment in the exhibition hall to the monitoring background through a complex cascade network system, which is easy to cause information leakage. The security and interactive performance of this type of system are poor, and it is impossible to isolate confidential equipment from the service network from a physical level, which has the risk of confidential information leakage. Alternatively, a separate control module is added to each device or a timing program is set. This type of control method cannot achieve intelligent control. If the power on and off time of a certain exhibition hall or all equipment needs to be adjusted, the administrator needs to reset and test the equipment one by one, which is a complicated and time-consuming process. In addition, this type of system does not involve scheduled inspections of equipment status, operation and maintenance plan management, electronic drawing management, personnel maintenance permissions, and regional control, which causes great inconvenience to the inspection and maintenance of exhibition hall equipment.

[0042] During specific implementation, through the interaction within the local area network of the local server, intelligent gateway and each control terminal, unified status monitoring and control of the equipment in each exhibition hall in the confidential exhibition hall can be achieved, thereby improving the monitoring and control efficiency of the equipment in each exhibition hall in the confidential exhibition hall.

[0043] like Figure 2As shown, the control terminal includes a first 485 communication unit, a voltage and current detection unit and a first execution unit. The 485 communication unit establishes a 485 bus connection with the intelligent gateway, and is used to transmit the status detection information to the intelligent gateway through the RS485 bus protocol, and receive the control instruction from the intelligent gateway. The voltage and current detection unit is used to collect the voltage and current information of the corresponding exhibition hall equipment, and the status detection information includes voltage and current information. The first execution unit is used to control the reclosing circuit breaker of the corresponding exhibition hall equipment to close or open according to the control instruction. Further, the control terminal also includes a first status detection unit, and the first status detection unit is used to collect the opening and closing state and the operating state of the reclosing circuit breaker, and integrate the opening and closing state and the operating state of the reclosing circuit breaker into the status detection information. The control terminal can use a corresponding embedded processing chip to process the collected data, such as voltage and current data, and execute the corresponding control instructions, such as the opening and closing control of the reclosing circuit breaker. The control terminal can be designed with protection functions such as overvoltage, undervoltage, overcurrent, and short circuit. The control terminal collects the voltage and current information of the exhibition hall equipment in real time and reports it to the local server. The local server will record the voltage and current information of each exhibition hall equipment in normal mode. When the corresponding voltage and current exceed the normal range, the local server will feedback the abnormal status to the user.

The device control management unit is used to generate control instructions for the corresponding exhibition hall equipment according to the determination result of the device power status monitoring unit and the set device control logic, such as setting the exhibition hall operation and closing date, setting the operation and closing time of the whole hall on weekdays, grouping the various equipment in the exhibition hall or managing them in different exhibition areas, one-key on / off of the whole hall equipment, one-key on / off by area, one-key on / off by equipment type, single device on / off, etc.

[0046] Furthermore, the local server also includes an operation and maintenance management unit, which is used to provide fault and operation and maintenance prompts for the exhibition hall equipment according to the judgment results of the equipment power status monitoring unit and the set equipment maintenance logic. For example, the operating status of each exhibition hall equipment is displayed; the equipment maintenance cycle is set and reminders are given when it is due; when the equipment fails during operation, the equipment failure information is entered to remind the maintenance personnel of the equipment failure and timely repair. The maintenance management unit can realize efficient fault and operation and maintenance management for each exhibition hall equipment, regular maintenance of equipment, equipment failure and fault solution and other operation and maintenance prompt information, which can provide reference for the subsequent timely resolution of equipment problems.

[0047] Furthermore, the local server also includes a drawing management unit, which is used to store and manage exhibition hall electronic drawings and exhibition hall equipment and control terminal wiring electronic drawings. The drawing management unit can realize electronic archiving management of confidential exhibition hall electronic drawings, exhibition hall equipment and control terminal and other electrical equipment wiring electronic drawings, so as to prevent the trouble of subsequent exhibition hall equipment maintenance caused by the loss of paper documents.

The rights management unit is used to authenticate and manage the rights of the login personnel, such as the rights allocation of ordinary personnel and management personnel, and the use of special encryption authorization for viewing and controlling more important equipment status information to prevent ordinary personnel from unauthorized viewing and operation, management or control personnel account password management, etc. The log management unit is used to record the login and operation information of the login personnel. The rights management unit can be used to realize the authentication and management of the local server login personnel, and the log management unit can be used to record the login and operation information of the login personnel to ensure the safe operation and use of the local server.

[0049] The local server can be a general-purpose processor, including a central processing unit (CPU), a network processor (NP), etc.; it can also be a digital signal processor (DSP), an application specific integrated circuit (ASIC), a field programmable gate array (FPGA) or other programmable logic devices, discrete gate or transistor logic devices, discrete hardware components, etc.
