Embodiment
Below in conjunction with accompanying drawing the present invention is further described fully from hardware composition, dual-computer redundancy heat.The hardware configuration of Fig. 1 embodiment of the invention.
Communications Management Units is made up of cabinet and various function module.Wherein, except that the panel module is installed in the front panel, other function modules all adopt the back of the body to insert the formula mode and install.CPU module, motherboard and power supply module are essential module, and serial ports module, accident signal module, KVM module, GPS module etc. can freely customize according to the function needs at other interior module, are distributed in 8 slots at device subrack back.CPU and power supply module can redundant configuration constitute Dual-Computer Hot-Standby System.Be equipped with the implementation description emphatically of part below with regard to dual-computer redundancy heat:
CPU module design: adopt technical grade ETX module loading plate to constitute.More than the dominant frequency 500M, internal memory 512M-1G DDR, solid-state storage 2G-8G, configuration can be upgraded with market.Contain 1 road USB2.0 interface, 1 road RS232C debug port and 4 road 10/100M self adaptation Ethernet interfaces, the Ethernet optical fiber interface is optional, and optical fiber interface meets the 100Base-FX standard.Ethernet interface 1 and 2 generally is used for communicating by letter in the institute, and it is standby to constitute two nets.Ethernet 3 generally is used for telemechanical and communicates by letter with 4 mouthfuls, supports a plurality of scheduling, supports that binary channels is standby.Usb compatible 2.0 and 1.0 standards are used to insert the generic USB peripheral hardware, comprise USB flash disk, portable hard drive etc.The CPU module has 4 tunnel USB interface in addition, draws by the KVM plate.1 tunnel inner RS232C serial port is used to connect the GPS module.8 road RS232C/485 serial ports are drawn with two blocks of serial ports plates.These are drawn interface and link to each other at other interior module with serial ports module, accident signal module, KVM module, GPS module etc. by motherboard, can freely customize according to the function needs, and CPU and power supply module can redundant configuration constitute Dual-Computer Hot-Standby System.
The design of panel module: panel has liquid crystal and no liquid crystal version.When the little display interface of needs, adopt liquid crystal panel, the touch-screen pattern manipulation interface.When the big display interface of needs, use no liquid crystal panel, external stand alone display, QWERTY keyboard and mouse.Use if only do Communications Management Units, can cancel display interface.Have only indicator lights such as a spot of operation, main frame prompting, fault above the no liquid crystal panel, can understand A, B redundancy switching mechanism more intuitively by indicator light.
For understanding A, B redundancy switching mechanism more intuitively, at first two-shipper A, B machine indicator light are done to introduce:
The signal lamp explanation:
The operation green light: long bright during the electrifying startup, enter running status after about 30 seconds, be 1 second flicker at interval;
The main frame green light: long bright expression is current to be main frame, and not working is expressed as standby host;
The fault red light: the bright or flicker expression of red light has dissimilar faults.Obtain accurately with reference to running log information.Failure cause.
The design of power supply module: this module is the dc inverter plug-in unit.The input of direct current 220V or 110V voltage behind the anti-interference filtration loop, four groups of direct voltages that utilize inversion and rectification principle output device to need, i.e. 1 road 5V, 1 road 12V, 2 road 24V.
A) 5V is the main power source of each module;
B) 12V is used for powering to panel liquid crystal.
B) the 24V first via is the power supply that is used to drive internal relay; 24V the second tunnel for outside open into power supply.
Switch electrical schematic diagram as Fig. 2 motherboard power supply; Fig. 3 motherboard expansion interface switches electrical schematic diagram.
Power supply switch circuit: all modules of supervisor link to each other by the cabinet motherboard, design has dual power supply switching circuit on the motherboard, power supply hardware realizes by PANASONIC DSP1-DC24V, the interlocking of DSP2a-DC24V relay node, guarantee synchronization only host CPU have the control right to use of serial ports.
Cooperate hardware competition logic, implementation is:
After powering on, the flicker of the run indicator of A/B machine can be asynchronous.After main frame (A or B) obtains effective clock, can to standby host to the time, the flicker of assisted running this moment lamp should be synchronous.Be running indicator glimmer synchronously the expression to the time function normal.Long bright this machine of the expression CPU of main frame green light is current to be main frame.Do not work and be expressed as standby host.After this machine CPU entered operation, by the software control of hardware competition logic OR, one of CPUA or B entered Host Status.Cooperate host signal and hardware commutation circuit, main frame obtains the control of serial ports, set up and institute in install communicate to connect.
A, B machine 1 second at interval power on successively, and the A machine should be main frame, running indicator is long bright in the start-up course, and startup is finished, after the main program operation, the running indicator flicker, the main frame indicator light A captain of CPU A and B is bright, and the B machine does not work, expression A is a main frame, B is a standby host, and Shutdown Hosts A, panel main frame should automatically switch to B machine (switch and do not have time-delay), this moment, public resource electric power loops such as serial ports module also automatically switched to B dynamo-electric source power supply by motherboard hardware relay node interlock function.
Dual-computer redundancy hardware switches shown in the two CPU wiring of accompanying drawing 4 motherboards electrical schematic diagram, the two CPU of software control are known masterslave state by internal communication protocol using, if working machine repeatedly resets or main commentaries on classics of controlled software is equipped with instruction, then discharge control automatically, after guest machine knows that the offside change is equipped with being instructed by the alternation of hosts of information or controlled software, provide the control that active and standby switch pulse obtains common source at once, backstage or telemechanical promptly automatically switch and cause new main computer unit operation.
External cabling pattern: after two-shipper powers on, it is standby that CPUA, B machine insert institute's two nets of interior switch formation by Ethernet interface or optical fiber interface 1 and 2 respectively, Ethernet 3 generally is used for telemechanical and communicates by letter with 4 mouthfuls, support a plurality of scheduling, the support binary channels is standby, public serial ports module in corresponding port configuration loading station or dispatching communication stipulations module, can be realized the operating scheme that dual-computer redundancy heat is equipped with after putting into operation as required.
Below announced the present invention with preferred embodiment, so it is not in order to restriction the present invention, and all technical schemes that scheme obtained of taking to be equal to replacement or equivalent transformation all drop in protection scope of the present invention.
