Embodiment
Below in conjunction with the drawings and specific embodiments, the present invention is further detailed.
Shown in Figure 1, a kind of based on full networked centralized control system, comprise user operation terminal 1, centralized control main frame and controlled module, wherein controlled module comprises control interface equipment 5 and controlled plant 6, centralized control main frame is at least two, for master redundancy Hot Spare in centralized control system, two i.e. the first main frame 2 and the second main frames 3 are adopted in the present embodiment, user operation terminal 1, first main frame 2, second main frame 3 and control interface equipment 5 are all connected with the network switch by wireless network (also can select wired connection, the present embodiment adopts wireless mode), build a full networked centralized control system.
User operation terminal 1, for man-machine interactive operation, generates corresponding instruction code according to user operation, and this instruction code comprises control command and other Business Processing instructions.First user operation terminal 1 establishes a communications link with the first main frame 2 in centralized control main frame, after successful connection, first main frame 2 is set to work at present main frame, the instruction code of generation, as the redundancy backup of the first main frame 2, to be sent to by user operation terminal 1 by network with the form of packet on work at present main frame i.e. the first main frame 2 in centralized control system by the second main frame 3.In the process, user can also carry out grand recording function, when user operates the corresponding control command code of generation in user operation terminal 1, carry out mode of operation switching, be switched in grand recording process, by control command code record in the grand object created, preserve this grand object, upgrade corresponding grand log file, macro operation according to user is repainted operation interface by user operation terminal 1, by this process, can the control command of the controlled plant 6 used be needed to be kept in grand object the user of generation, when user is again with these equipment of identical pattern, do not need successively to these operates, only need to perform the grand object preserved, automatically these equipment can be operated successively, decrease the process of the complicated repetitive operation of user, decrease the operating time, native system is made more to be close to the users day with changeable specific requirement.
In the present embodiment, centralized control main frame is two, i.e. the first main frame 2 and the second main frame 3, wherein, first main frame 2 is work at present main frame, for receiving the packet that user operation terminal 1 sends, and packet is resolved, judgement is control command or other Business Processing instructions, if other Business Processing instructions, then carry out other business associative operations, if control command, then parse destination address or the port information of the output of this control command, then this instruction of Reseal, after Reseal by ICP/IP protocol by data packets to destination (also transmitting by other host-host protocols).Second main frame 3 is as the redundancy backup of the first main frame 2, when the first main frame breaks down, when cannot work, such as the first main frame 2 is lost suddenly with the connection of user operation terminal 1, by wireless network (or cable network), work is seamlessly switched to second main frame 3 from First main frame 2, thus do not affect whole system work, improve the reliability of whole system.In actual mechanical process, the number of host for redundancy backup can be selected according to the work requirements of reality.
The packet that control interface equipment 5 sends for receiving work at present main frame, and this packet is resolved, judge whether these data are valid data, if valid data then take out control command, control command is put in outgoing queue, send to controlled plant 6 successively.Needing the regular hour because controlled plant 6 responds an instruction, for preventing control command from exceeding controlled plant response speed, after one period of stand-by period is set, then next control command being sent in controlled plant 6.The control command that controlled plant 6 sends for receiving control interface equipment, completes corresponding control action according to control command.Wherein, the stand-by period of setting determines according to the controlled plant response speed of reality and time.
In the present embodiment, control interface equipment 5 comprises serial server, infrared emission server, dry contact control device and volume controller, dissimilar according to controlled plant 6, is connected electrically in respectively by serial server, infrared emission server, dry contact control device and volume controller on corresponding controlled plant 6.In real work, can dissimilar according to controlled plant 6, suitable increase or reduce dissimilar control interface equipment 5.
See Fig. 2, based on full networked centralized control method, it is characterized in that, comprise the following steps:
Step one: read local profile in user operation terminal, set up centralized control main frame to be connected with the communication network of user operation terminal, centralized control main frame is set to work at present main frame, check the system file version between user operation terminal and work at present main frame, work at present main frame reads user property and device attribute, draw out user interface, enter man-machine interactive operation.Be connected setting up the communication network of centralized control main frame with user operation terminal, centralized control main frame is set in work at present host process, comprise user operation terminal and the first main frame in centralized control main frame and set up communication network when being connected unsuccessful, user operation terminal is set up communication network with next backup host in centralized control main frame be connected, and this main frame is set to work at present main frame.
Step 2: user carries out control operation at operating terminal, generates corresponding control command, and control command is sent on work at present main frame by network by user operation terminal.User is when operating terminal carries out control operation, also the control command of generation can be carried out grand recording operation, be recorded in grand object by control command, preserve this grand object, macro operation according to user repaints operation interface at user terminal, when user uses these equipment with identical pattern again, do not need successively to these operates, only need the grand object that executable operations interface generates, automatically these equipment can be operated successively, decrease the process of the complicated repetitive operation of user, decrease the operating time.When control command is sent on work at present main frame by network by user operation terminal, if do not send successfully, then control command is sent to next backup host in centralized control main frame, and this main frame is set to work at present main frame.
Step 3: work at present main frame is resolved this instruction after receiving the control command of operating terminal transmission, parses the destination address that this instruction exports, then this instruction is encapsulated, and sends to the control interface equipment connecting controlled plant.
Step 4: after control interface equipment receives the instruction of current main control system transmission, this instruction is checked whether to be valid data, if this instruction is put in outgoing queue by valid data again, send to the controlled plant with this control interface equipment connection successively, controlled plant completes corresponding control action according to control command.For preventing control command from exceeding controlled plant response speed, the built-in instruction queue buffer of control interface equipment, after arranging one period of stand-by period, then is sent to next control command in controlled plant.Wherein, the stand-by period determines according to the controlled plant response speed of reality and time.
