Description of drawings
Fig. 1 is the structural representation of the control module of specific embodiments of the invention;
Fig. 2 is the structural representation of the control module of certain communication equipment of specific embodiments of the invention.
Embodiment
Below in conjunction with the drawings and specific embodiments the present invention is done to introduce further, but not as a limitation of the invention.
In communication equipment, control module comprises the master control module and from control module, when the master control module was working properly, the uplink communication Interface and Communication link of master control module connected, and was used for standby and be in idle condition from each uplink communication interface of control module; When the master control module breaks down, directly automatically the uplink communication interface of master control module is connected with uplink communication interface from control module, realize the master control module thus and from the switching between the control module.At this moment.Master control module uplink communication interface not only is connected with communication link, also with from control module uplink communication interface is connected, and makes the upstream data reality of network by exporting from control module uplink communication interface.
Certainly, when the master control module broke down, it also can be to initiate through webmaster to the switching from control module, at this moment, carries out following step successively:
A. the master control module sends a warning message to outside webmaster;
B. after webmaster receives the warning information of master control module, to sending switching command from control module;
C. after receiving switching command from control module, its uplink communication interface is connected with described master control module uplink communication interface.
Accordingly, as shown in Figure 1, also propose a kind of master control module in the embodiments of the invention and from the switched system of control module, this system can realize the master control module and from the reliable switching of control module.In the system except the master control module with from control module, also increase a handover module is set, described handover module is used at the primary importance state uplink communication Interface and Communication link of master control module being connected, make from the uplink communication interface of control module at second place state and to be connected with the uplink communication interface of master control module, it switches to second place state with location status from the primary importance state after knowing that the master control module breaks down.
Illustrate a bit: in above-mentioned handover module, it knows that it can be to be obstructed by the networking transmitting uplink data directly to judge that the master control module breaks down, can also be by the master control module, realize alternately, be specially from the signal between control module, handover module and the outside webmaster:
Handover module receives after the connection signal of control module in this system, and location status is switched to second place state from the primary importance state;
At this moment, described master control module is used for when breaking down, and sends a warning message to outside webmaster;
Described from control module, after being used to receive switching command, send the connection order to handover module; Wherein said switching command is after outside webmaster receives the warning information of master control module, to what send from control module.
From said method and system, as can be seen, when the master control module breaks down, it is with when control module switches, link to each other with the uplink communication interface of master control module from the uplink communication interface of control module, the upstream data of network is actual in exporting from control module, and still the physics output interface of network uplink data remains the master control module at this moment, this has just kept the data link of uplink network interface not change, thereby has guaranteed the reliability service of system.
Further, with reference to master control module in certain communication equipment control module shown in Figure 2 with from the embodiment more specifically of system that control module is switched, control module adopts the mode of 1+1 master-slave back-up in this communication equipment, at this moment, adopt the line switching of a plurality of high speeds in the handover module, (Complex Programmable Logic Device, CPLD) realize according to its control signal that receives by circuit by programmable logic device for each above-mentioned high-speed line on off state.Data link is connected to the uplink communication interface of master control module in actual networking, when the master control module is normally moved, each high-speed line switch is connected the uplink communication interface and the uplink communication link of master control module, when the master control module breaks down, master control module and switch from control module, by the CPLD circuit high-speed line position of the switch state is changed, to be connected to from the uplink communication interface of control module on the physical channel of uplink network interface of master control module, do not having under technical staff's situation at the scene like this, also need not change networking, just can realize the master control module and, avoid the communicating interrupt of uplink network interface from the switching of control module.
From the foregoing description as can be seen, master control module proposed by the invention and when between control module, switching, what switch is the physical link of uplink communication interface, the data path that does not relate to the uplink communication interface, and the master control module can not have influence on the physical link of uplink communication interface owing to fault crashes, thereby switches the reliability height; On the other hand, the switching that handover module proposed by the invention carries out between primary importance state and the second place state is to realize according to its control signal that receives, do not need technical staff's execute-in-place, shortened the equipment switching time that causes because of the control module fault.
In addition, also carry out following supplementary notes for the foregoing description: (1) is though just carry out the master control module when master control module breaks down in the foregoing description and from the switching between the control module, but in other embodiments, above-mentioned switching also can be with other incidents as trigger condition; (2) proposing handover module in the foregoing description can be realized by CPLD, also can adopt application-specific integrated circuit (ASIC) (Application Specific Integrated Circuit in other embodiments, ASIC) or programmable gate array (FieldProgrammable Gate Array, FPGA) etc. method realizes.
Should be understood that; concerning the those of ordinary skill in field, the technology of the present invention place; can be equal to accordingly according to technical scheme of the present invention and design thereof and change or replace, and all these changes or replacement, all should belong to the protection range of claims of the present invention.
