Description

Technical Field

[0001] The present invention relates to the field of computer technology, and in particular to a multi-mode intelligent control device and method for a command center. Background Art

[0002] With the development and application of information technology, various industries usually build unified command and comprehensive management command centers, dispatch centers, operation centers and other comprehensive infrastructure and supporting systems that integrate control, operation and service in order to solve the problems of "data chimneys" and "information islands" in the process of development and management, such as fragmentation, poor information communication, and promote information sharing and efficient use of resources. Especially in the field of social public security and urban management, with the development of information construction, all cities and prefectures have built command centers with functions such as command and dispatch, centralized control, comprehensive management, analysis and judgment, and emergency disposal.

[0003] Since the command center is where information resources are relatively concentrated and has good practical effects, in addition to daily work, it usually has the functions of visitor reception and external display during operation. When the command center is used for visits and displays, in order to achieve the best display effect, various facilities in the command center will be turned on in various states different from the normal working mode. Combined with different external environmental factors, each device will make adaptive adjustments to the switch state according to external conditions.

[0004] In actual use, the application scenario system of the command center includes the basic environment system and the intelligent information system. Among them, the basic environment system usually includes the indoor ceiling lamps of the command center, the indoor wall lamps of the command center, the ground (step) decorative lamps of the command center, the decorative lamps of the command center console, as well as the indoor air conditioning system of the command center, the curtain system of the command center, etc. The intelligent information system includes the command center display large screen system, the command center indoor broadcasting system, the command center multimedia playback workstation, the command center console seat workstation, etc. At present, during the operation and use of the command center, according to the needs of the application scenario, each system basically adopts the method of independent operation and control to meet the needs of the actual scenario.

[0005] Since the command center has many systems and equipment, the operation process is cumbersome and easy to forget. Even in the same application scenario, different personnel operate the systems and equipment in different ways. The reasons are mainly:

[0006] (1) Each application scenario system or entity in the command center is independent of each other, and each system and entity is managed independently;

[0007] (2) When functional customization and expansion are required, the existing practice is usually to expand and develop based on the existing system of a certain system supplier. Therefore, it lacks universality and has limited expansion capabilities;

[0008] (3) Currently, the existing smart home mode control methods in the market lack unified standards, so most of them are based on proprietary products to achieve interconnection, and there are relatively few access devices and access methods, and they are rarely used in industries and corporate production.

[0009] (4) In terms of the application of modes for different scenarios, the relevant modes are mostly fixed in a certain system device of many systems. The determined modes cannot be modified during user use, which lacks flexibility and results in a poor user experience. Summary of the invention

[0010] In order to reduce the workload of personnel in the application process of various scenarios in the command center, improve the comfort of application scenarios, optimize resource allocation, and achieve the best practical effect, according to the application scenarios, the present invention adopts an intelligent way to comprehensively manage the many systems and equipment of the command center, and provides a multi-mode intelligent control device and method for the command center.

[0016] A multi-mode intelligent control method for a command center is based on the multi-mode intelligent control device for the command center: after the intelligent control device is powered on,

[0017] 1) Embedded operating system startup:

[0018] First, load the boot program Bootloader to initialize the device's onboard processor and peripheral components;

[0035] In order to make the technical solutions and advantages of the present invention more clearly understood, the present invention is further described in detail below in conjunction with its embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not used to limit the present invention. For those skilled in the art, other system uses or features of this embodiment will become apparent after reviewing the following detailed description.

[0036] In the command center multi-mode intelligent control device of this embodiment:

[0037] The hardware of the control device adopts a low-power, high-performance microprocessor based on the ARM9 RISC reduced instruction set, and manages SDRAM and NAND FLASH storage expansion through the internal bus. 2 C, UART, USB and other buses and channels for peripheral circuit interface expansion. The control device board is based on the ARM9 RISC microprocessor, and a power converter is set to realize the power conversion from the input AC 220V power supply to the onboard components and circuits, and a cooling fan is set to remove the internal heat of the device in time. The control device is equipped with a power management unit PMU to coordinate with the microprocessor to monitor and manage the energy consumption of the onboard components, and adjust and shut down unnecessary system components according to the working status of the device. The control device expands the storage of the processor chip bus, stores the application programs and configuration data related to the command center working mode in FLASH, and DDR and EEPROM are used to temporarily store data during the operation of the device, communicate with external systems and equipment through the device port, and forward data when communicating with the application client.

[0038] The onboard microprocessor of the control device is expanded through the interface chip module. The Ethernet management unit and the microprocessor are expanded through the address bus AB and the data bus DB. The RS485 management unit is expanded through the UART serial bus. The wireless interface between the control device and the wireless application client (such as PAD) is expanded through the WIFI management unit based on the USB bus. The I / O expansion unit is expanded through the I of the microprocessor. 2 C bus for DI / DO port expansion.

[0039] The structure of the control device and the layout of the main components on board are shown in the figure below: Figure 1As shown. Among them, 1001 is the control device chassis, 1002 is the control device installation ear, and the ear is provided with a mounting hole. The device can be fixed on the rack with screws through the ears on the left and right sides of the device. On the front side of the device, a power switch 1003 is set to turn the device on and off. When the device is in the on state, the power switch indicator light 1004 is lit green, and the indicator light 1004 is off when it is off. A working mode indicator light 1005 is set on the front side of the device to identify the current working mode of the device (such as when the command center application scenario system works in the reception mode, the second indicator light of 1005 is lit green, otherwise it is off). 1006 is the reset button of the device embedded operating system, which is used to reset and restart the software system of the device, and 1007 is the reset indicator light. In order to avoid misoperation caused by inadvertent touch, 1006 uses an embedded button. When the device is reset and restarted in the software system, the indicator light 1007 flashes, and the indicator light 1007 is off after the restart is completed. The front panel of the device is provided with a debugging console port 1008 and a debugging status indicator light 1009, which are used by development and debugging personnel to develop and debug the software of the device. Through the console port, operations such as onboard program download, debugging, program running status monitoring, onboard application program parameter configuration and modification, and onboard component parameter modification can be performed.

[0040] The I / O expansion unit of the control device to the DI / DO terminal circuit adopts optical coupling isolation. Figure 1 Among them, 1010 is the input signal optocoupler isolator, 1016 is the DI input signal wiring terminal, 1015 is the DI input signal indicator, 1014 is the output DO signal wiring terminal, 1013 is the DO output relay, 1012 is the output DO signal indicator, and 1011 is the output signal optocoupler isolator. The DI / DO output optocoupler isolation to the wiring terminal row adopts a double-layer circuit board design according to the number of signals, such as Figure 1 In order to facilitate use and wiring, the device adopts the rear panel wiring method. In addition to the above DI / DO terminals, the rear panel of the device is equipped with RJ45 network interface, RS485 serial data interface, and WIFI wireless interface, as shown below: Figure 11019, 1020, 1021. Signal indicators 1017 and 1018 are set between the network interface, RS485 interface, wireless interface and interface management unit to identify the current communication and data transmission status between the device and the external system and equipment. When the communication with the external system and equipment is established normally, the first row 1017 corresponding port indicators light up green. If the communication cannot be established, the first row 1017 corresponding port indicators flash green, and the buzzer 1023 beeps intermittently (when the WIFI wireless port communication cannot be established, the port communication indicator flashes, and the 1023 buzzer beeps continuously). At this time, the buzzer is turned off by pressing the 1022 buzzer button, and the first row 1017 corresponding port indicators continue to flash green. When the communication failure between the corresponding port and the external system and equipment is eliminated and can communicate normally, the first row 1017 corresponding port indicators stop flashing and become green. The network interface, RS485 interface, wireless interface and external system and equipment communication are established normally, and control command transmission and reception are started. When the command data transmission and reception are normal, the second row 1018 corresponding port indicator lights up yellow. When the control command data transmission and reception are abnormal, the second row 1018 corresponding port indicator lights flash yellow, and the buzzer 1023 beeps intermittently (no buzzer does not beep when the WIFI wireless port data transmission and reception are abnormal). At this time, the buzzer is turned off by pressing the 1022 buzzer button, and the second row 1018 corresponding port indicator lights continue to flash yellow. When the corresponding port and the external system, equipment communication fault is eliminated and the control command data can be transmitted and received normally, the second row 1018 corresponding port indicator lights stop flashing and turn into a yellow light state.

[0041] The control device system uses an embedded operating system based on LINUX, which is responsible for the configuration and driver management of the onboard system hardware and software of the control device, the resource scheduling and management of the onboard components, the task and process management of the operating system and applications, and the real-time and historical data storage and management of the system and applications. Figure 3 As shown in the figure, the system software is functionally divided into the interface driver layer, operating system layer, application protocol layer and application service layer. The interface driver layer is the LINUX-related interface driver, responsible for the management of network, RS485, WIFI and other onboard interface chips, and the operating system layer coordinates system tasks and processes.

[0042] The application program of the control device is built on the application protocol and application service layer based on the operating system. The control device communicates with the wireless client application terminal (such as PAD) through the WIFI wireless interface, accepts the mode control instructions issued by the PAD client application terminal, and feeds back the communication and device status of the external system and equipment to the PAD terminal. The application program includes the command center's working mode logic judgment and execution program in different application scenarios, and the control instruction communication protocol data packet conversion program for different external systems and equipment in different working modes. The control device sends and receives control instructions according to the communication protocol corresponding to the external system and equipment it communicates with, and sends the feedback of the external system and equipment status information (such as dry contact DI information) to the PAD client application terminal.

[0043] Through the Console debugging interface, you can download and debug system programs based on the LINUX development environment, monitor their running status online, and configure the parameters of onboard devices. At the same time, through the debugging interface, you can program the application, modify and set parameters, and monitor the program running status online.

[0044] After the above intelligent control device is powered on, it first loads the boot program Bootloader to initialize the device's onboard processor and peripheral components, then starts the LINUX kernel program to initialize each kernel module, then mounts the root file system, configures system files and application database files, and initializes the onboard component drivers to complete the device system startup. During the startup self-test, if a fault is found, the onboard buzzer (such as Figure 1 1023) will emit a continuous beeping sound to remind you that you can press the button ( Figure 1 1022) temporarily turns off the buzzer alarm. If the onboard fault is not resolved, press the buzzer switch button again, the onboard buzzer will continue to emit continuous buzzer alarm prompts. When the onboard fault is eliminated, the buzzer alarm prompt is completely eliminated.

[0045] After the embedded operating system of the control device is started, the control device automatically starts the multi-mode intelligent control application and initializes the mode parameters, and then attempts to communicate and connect with external systems and devices through the network and RS485 interface in turn. The communication connection request between the control device and the external system and device follows the custom protocol. For example, when the control device makes a connection request through network port 1, it sends a hexadecimal data packet "66 (frame header) + AC (connection request identifier) ​​+ XX (external system, device address number, length is 1 Byte, address range is 00~FF) + EE (frame tail)". If the external system or device is successfully connected, the hexadecimal data packet "55 (frame header) + CB (connection response identifier) ​​+ XX + EE (frame tail)" is fed back. If the external system or device does not respond or feeds back a hexadecimal data packet "55 (frame header) + C0 (connection cannot be established identifier) ​​+ XX + EE (frame tail)", it indicates a connection error. The communication status between the network port 1 of the control device and the external system and device can be seen through the above Figure 1 The indicator light and buzzer sound alarm of the corresponding port of network port 1 in row 1017 can be used to identify it.

[0046] The control device can send connection requests to multiple external systems and devices on the network connected to it through network port 2. The hexadecimal data packet it sends is "66 (frame header) + AE (connection request identifier) ​​+ XX (external system, device address number, length is 1 Byte, address range is 00~FF) + EE (frame tail)". If the external system or device is successfully connected, the hexadecimal data packet "55 (frame header) + EB (connection response identifier) ​​+ XX + EE (frame tail)" will be fed back. If the external system or device has no response or feeds back the hexadecimal data packet "55 (frame header) + E0 (connection cannot be established identifier) ​​+ EE (frame tail)", it indicates a connection error. The communication status between the control device network port 2 and the external system and device can be checked through the above Figure 1 The corresponding port indicator light and buzzer sound alarm of network port 2 in row 1017 can be used to identify it.

[0047] When the control device sends a connection request to an external system or device via RS485 bus, the data packet format is "66 (frame header) + AA (connection request identifier) ​​+ XX (external system or device address number, length is 1 Byte, address range is 00~FF) + EE (frame tail)". If the external system or device is successfully connected, a hexadecimal data packet "55 (frame header) + BB (connection response identifier) ​​+ XX + EE (frame tail)" is fed back. If the external system or device does not respond or feeds back a hexadecimal data packet "55 (frame header) + 00 (connection cannot be established identifier) ​​+ XX + EE (frame tail)", it indicates a connection error. The communication status between the RS485 port of the control device and the external system or device can be checked through the above Figure 1The corresponding port indicator light and buzzer sound alarm of RS485 in row 1017 can be used for identification.

[0048] The communication between the control device and the client wireless application terminal is initiated by the application terminal. After clicking the APP on the client wireless application terminal to start running, the PAD terminal APP application automatically requests to establish a connection with the control device via wireless. The client application terminal application APP sends a hexadecimal data packet "88 (frame header) + AA (connection request identifier) ​​+ FF (frame tail)" to request to establish a WIFI wireless connection with the control device. The control device feeds back a data packet "77 (frame header) + BB (connection response identifier) ​​+ FF (frame tail)" to indicate that the connection is successful. At this time, Figure 4 The 4004 part of the display shows the "Current: Connection Success!" field, where the "Connection Success!" field is displayed in green. If the control device does not respond or feedbacks a hexadecimal data packet "77 (frame header) + 00 (connection cannot be established mark) + FF (frame tail)", it means a connection error. Figure 4 The 4004 part displays the "Current: Connection Failed!" field, where the "Connection Failed!" field is displayed in red and flashes.

[0049] After the control device establishes communication with the connected external system and equipment through the network port and RS485 port, it controls the application scenario-related systems and equipment according to the operation mode selected by the PAD wireless application client terminal. The control device sends a data packet format of "66 (frame header) + CX (control instruction identifier, length is 1 Byte) + XX (external system, device address number, length is 1 Byte, address range is 00~FF) + EE (frame tail)" to the external system and device connected to it through network port 1. The CX field in the data packet is defined as needed (such as C0 indicates shutdown, C1 indicates startup, C3 indicates playing audio and video file 1, C4 indicates playing audio and video file 2, etc.). The external system and device respectively feedback "55+CE (control instruction execution success identifier) ​​+ XX (external system, device address number) + EE", or "55+CF (control instruction execution failure identifier) ​​+ XX (external system, device address number) + EE" data packets to the control device network port 1 to indicate whether the execution of the instruction sent by the control device is successful or not. The execution of the instruction is indicated by Figure 1 The corresponding indicator light and buzzer alarm sound of the network port 1 in row 1018 can be known. At the same time, the execution status of the external system and device instructions can be displayed on the PAD wireless application client terminal interface, such as Figure 4 As shown in the 4006 area.

[0050] Similarly, the control device sends a data packet through network port 2 in the format of "66 (frame header) + EX (control instruction identifier, length is 1 Byte) + XX (external system, device address number, length is 1 Byte, address range is 00~FF) + EE (frame tail)" to control the external system and device connected to it. The field EX is defined as needed (such as E0 indicates shutdown, E1 indicates startup), and the external system and device respectively feedback the data packet in the format of "55+EE (control instruction execution success identifier) ​​+ XX (external system, device address number) + EE" or "55+EF (control instruction execution failure identifier) ​​+ XX (external system, device address number) + EE" to network port 2 to indicate whether the execution of the instruction sent by network port 2 is successful. Figure 1 The corresponding indicator lights and buzzer alarm sounds of network port 2 in row 1018 can show the execution status of network port 2 commands. At the same time, the execution status of external system and device commands is displayed on the PAD application client terminal interface, such as Figure 4 As shown in the 4006 area.

[0051] The control device controls the external system and device connected to it by sending a data packet in the format of "66 (frame header) + 1X (control instruction type identifier, length is 1 Byte) + XX (control instruction parameter identifier, length is 1 Byte) + XX (external system, device address number, length is 1 Byte, address range is 00~FF) + EE (frame tail)" through the RS485 port. The external system and device respectively feedback a data packet in the format of "55+B1 (control instruction execution success identifier) ​​+ XX (external system, device address number) + EE" or "55+B0 (control instruction execution failure identifier) ​​+ XX (external system, device address number) + EE" to network port 2 to indicate whether the execution of the sent instruction is successful. Similar to the above, the execution status of the control instruction sent by the control device through the RS485 port can be viewed through the device port indicator light and the wireless client terminal interface.

[0052] After the control device establishes communication with the client wireless application terminal, the application mode control instruction between the control device and the client wireless application terminal is initiated by the application terminal. The client wireless application terminal sends the application scenario system working mode control instruction according to the user's selection, and accepts the mode execution result instruction fed back by the control device. For example, the client wireless application terminal sends the mode selection data packet instruction of "88 (frame header) + 1X (first-level mode identifier, X is 0~F, length is 1Byte) + 2X (second-level mode identifier, X is 0~F, length is 1Byte) + FF (frame tail)". At this time, if the control device feeds back "77+BX (X is 0~F, control mode execution success identifier) ​​+ FF (frame tail)", it means that the control mode X is executed successfully, and the feedback "77+BF (control mode instruction execution failure identifier) ​​+ XX (external system and device address number where execution failed) + EE" means that the control mode execution failed. The execution status of the mode selected by the client wireless application terminal can be viewed in real time on the APP application interface, such as Figure 4 As shown in part 4004.

[0053] According to the actual use of the command center in operation, the application scenarios of the command center basically include reception waiting state, normal reception state, normal working state, and idle cleaning state. Therefore, the corresponding application control modes of the command center application scenario system include reception waiting mode, reception mode, working mode, sleep mode, and several first-level modes such as single (control) mode. The application scenario systems involved include air conditioning system, electric curtain system, command center indoor lighting system, command center projection screen system, command center background music system, command center media workstation system, command center seat workstation system, and command center operation desk lighting system. According to the use of the command center in different seasons and day and night, the working mode of the command center can be further subdivided into several second-level modes, such as the waiting mode can be subdivided into spring and autumn daytime waiting mode, summer daytime waiting mode, winter daytime waiting mode, night waiting mode, etc. The reception mode can be subdivided into spring and autumn reception mode, summer reception mode, and winter reception mode. The working mode is subdivided into spring and autumn working mode, summer working mode, and winter working mode.

[0054] During the use of the control device, by selecting the mode on the client wireless application terminal, the control device establishes communication with each system of the application scenario through Ethernet, RS485, dry contact DI / DO, and controls the equipment and controllers of the relevant system to achieve the equipment working state (application mode) that is not set by the application scenario. Figure 4The application interface selects the summer daytime waiting mode (secondary mode) under the waiting mode (level 1 mode). According to the mode setting, the PAD wireless application terminal sends control instructions to the control device. The control device communicates with the external system and equipment and sends control instructions according to the internal summer daytime waiting mode parameter settings. At this time, the air-conditioning system turns on cooling and sets the temperature to 26°C. The electric curtain system curtains are opened; the ceiling main lighting, auxiliary lighting, blue light strip rendering lighting, warm light strip rendering lighting, and indoor surrounding blue light strip rendering lighting of the indoor lighting system, floor warm light strip rendering lighting, and blue light strip rendering lighting are all turned off; the command center projection screen system, background music system, media playback workstation system, and operating desk seat workstation system are turned off; the front panel interior lights and front panel surrounding decorative lights of the operating desk lighting system are turned off, and the side panel LOGO lights are turned on. Similarly, when the customer application terminal passes Figure 4 When you select the winter daytime reception mode (secondary mode) under the reception mode (first-level mode) in the application interface, according to the mode setting, the control device will send control instructions to the external systems and equipment according to the internal mode parameter settings, and automatically operate. At this time, the air-conditioning system turns on the heating and sets the temperature to 20°C, and the electric curtains are automatically closed; the indoor lighting system's ceiling main lighting, auxiliary lighting, blue light strip rendering lighting, warm light strip rendering lighting, and indoor surrounding blue light strip rendering lighting, floor warm light strip rendering lighting, and blue light strip rendering lighting are all turned on; the command center's large-screen projection system, background music system, media playback workstation system, and operating desk seat workstation system are all turned on, and the media playback workstation starts playing video promotional film files; the front panel interior lights, front panel surrounding decorative lights, and side panel LOGO lights of the operating desk lighting system are all turned on. Similarly, when in Figure 4 When the shutdown mode is selected in the application interface, the control device sends instructions to the external systems and devices according to the internal setting mode, and all the related devices of the above application systems are shut down and enter the dormant state.

[0055] Figure 4 The schematic diagram of the wireless application terminal mode control operation interface is given, where 4001 is the set 5 first-level mode selection buttons. Click different operation buttons and further select the corresponding second-level mode. The application terminal will send the corresponding mode command to the intelligent control device. The intelligent control device receives the mode control command and performs logical judgment according to the internally stored application mode control program, and controls the relevant equipment and controllers through the interface with the external system and equipment. Among the above 5 first-level modes, when the waiting mode, working mode, and reception mode are clicked, the operation interface enters the second-level mode selection interface. After the user selects the second-level mode, the application interface will be Figure 4Area 4004 of the display shows the current mode information, such as "Current: Reception mode -> Summer reception mode". At the same time, areas 4003 and 4002 show the system name and communication status of each external system and device in this mode. When the communication is normal, it will be green, and when the communication fails, it will be red. Area 4006 shows the real-time switch status of the controllers and devices under each external system and device.

[0056] When Figure 4 When the single mode button is selected on the interface, the application terminal enters the single control mode of the external system and device. By selecting the external system and device to be controlled, it can be individually controlled. At this time, after the wireless application terminal sends instructions to the controller, the controller will not make logical judgments, but will directly perform independent control according to the control protocol between it and the external system and device. Figure 4 The wireless application terminal operation interface sets the shutdown mode, which is used for comprehensive control when the command center is idle or cleaning. When this mode is selected, the control device will send control instructions to the application scenario systems of the command center to put them in a shutdown and dormant state.
