Abstract
The invention discloses an upgrade control method. The upgrade control method includes the steps that a circuit is selected according to a current working condition of a communication system, a suitable processor is selected to control output signals, namely, when the communication system is in a normal working state, a master processor controls the output signals; when the communication system is in an upgrade state, a co-processor controls the output signals. The advantage that the co-processor is not needed to be upgraded is used by the upgrade control method and a control module, the advantages of the co-processor and the advantages of the master processor are combined, and the hidden danger that in the prior art the output signals cannot be controlled when a system is upgraded is removed.
Description
Technical field
The present invention relates to upgrade technique, particularly relate to a kind of upgrade control method and control module, belong to communication technical field.
Background technology
In prior art, when upgrading to communication system, directly adopting pin to latch mode, part output pin state being kept, reaches the state of stable output signal with this.
But when communication system is in escalation process, namely new content covers in the program of old content, the primary processor being equivalent to communication system carries out format manipulation to old content, and the output signal of communication system cannot the control of host processor.
Summary of the invention
The object of this invention is to provide a kind of upgrade control method and control module, communication system can be made when primary processor empties old content, output signal is controlled.
In order to realize described object, the invention provides upgrading and controlling control module, comprising primary processor, coprocessor, the first digital to analog converter, the second digital to analog converter, selection circuit; Primary processor connects the first end of the first digital to analog converter and coprocessor respectively; The other end of the first digital to analog converter connects the first end of selection circuit; Second end of coprocessor connects the second digital to analog converter; The other end of the second digital to analog converter connects the second end of selection circuit; 3rd end of the three-terminal link selection circuit of coprocessor.
Wherein, preferred implementation is: coprocessor is set to CPLD or FPGA.
The present invention provides the upgrade control method based on above-mentioned upgrade control module simultaneously, and first, the 3rd end of coprocessor will select signal to export the receiving end of selection circuit to; Secondly, selection circuit judges according to selection signal the duty that communication system is current; Again, selection circuit, according to the current operating state of communication system, selects suitable processor to control output signal; Finally, selection circuit outputs signal to communication system.
Wherein, preferred implementation is: when communication system is in normal operating conditions, and primary processor controls output signal.
Wherein, preferred implementation is: when communication system is in upgrade status, and coprocessor control outputs signal.
Wherein, preferred implementation is: after primary processor returns termination signal to coprocessor, communication system exits upgrade status; Then coprocessor outputs control signals to the receiving end of selection circuit, and communication system carries out normal operating conditions.
Upgrade control method of the present invention and control module achieve when communication system upgrading, what output signal is stable and controlled, compared with prior art, upgrade control method of the present invention and control module make use of the advantage that coprocessor does not need to upgrade, the advantages of primary processor and coprocessor is got up, when solving system upgrade of the prior art, output signal uncontrollable hidden danger.
Accompanying drawing explanation
Below in conjunction with drawings and Examples, structure of the present invention is further illustrated.
Fig. 1 is the structural representation of upgrade control module of the present invention.
Fig. 2 is the schematic flow sheet of upgrade control method of the present invention.
Embodiment
Below in conjunction with accompanying drawing, upgrade control method of the present invention and control module are described further.
Fig. 1 is the structural representation of upgrade control module of the present invention.Upgrade control module of the present invention comprises primary processor 11, coprocessor 12, first digital to analog converter 21, second digital to analog converter 22, selection circuit 30, wherein, primary processor 11 connects the first end 121 of the first digital to analog converter 21 and coprocessor 12 respectively, the other end of the first digital to analog converter 21 connects the first end 301 of selection circuit 30, second end 121 of coprocessor 12 connects the second digital to analog converter 22, the other end of the second digital to analog converter 22 connects the second end 302 of selection circuit 30, 3rd end 123 of coprocessor 12 is connected with the 3rd end 303 of selection circuit 30 simultaneously.
Wherein, the 3rd end 123 of coprocessor 12 exports the 3rd end 303 selecting signal to selection circuit 30, and when communication system is in normal operation, the selection signal behavior primary processor 11 that selection circuit 30 exports according to coprocessor 12 controls output signal; When communication system is in upgrade status, the selection signal behavior coprocessor 12 that selection circuit 30 exports according to coprocessor 12 controls output signal; Wherein, coprocessor 12 can be set to CPLD (Complex Programmable Logic Device, CPLD), or coprocessor 12 is FPGA (Field-Programmable Gate Array, field programmable gate array).
Fig. 2 is the schematic flow sheet of upgrade control method of the present invention.Upgrade control method of the present invention comprises the following steps:
First, the 3rd end 123 of coprocessor 12 will select signal S
xexport the receiving end 303 of selection circuit 30 to;
Secondly, selection circuit 30 is according to selection signal S
xjudge the current operating state of communication system, work as S
x=S
1time, communication system is in normal operating conditions; S
x=S
2, communication system is in upgrade status.
Again, selection circuit 30 is according to selection signal S
xthe current operating state of the communication system judged, selects suitable processor to control output signal; Wherein, when communication system is in normal operating conditions, primary processor 11 controls output signal; When communication system is in upgrade status, coprocessor 12 controls output signal;
Wherein, at the end of communication system upgrading, primary processor 11 returns termination signal S
pto coprocessor 12, coprocessor 12 receives the termination signal S of primary processor 11
pafter, communication system exits upgrade status; Then coprocessor 12 exports control signal S
1to the receiving end of selection circuit 30, communication system recovers normal operating conditions.
Finally, selection circuit 30 outputs signal back in communication system.
Upgrade control method of the present invention and control module are mainly used in EDFA (Erbium-Doped OpticalFiber Amplifier, Erbium-Doped Fiber Amplifier) etc. in product, still need to control in the communication products of output signal when being applicable to control module upgrading.
Upgrade control method of the present invention and control module achieve when communication system upgrading, what output signal is stable and controlled, compared with prior art, upgrade control method of the present invention and control module utilization factor coprocessor 12 do not need the advantage of upgrading, the advantages of primary processor 11 and coprocessor 12 is got up, when solving system upgrade of the prior art, output signal uncontrollable hidden danger.
As described above, be only preferred embodiment, and not for limiting the scope of the invention, all equivalences done according to the present patent application the scope of the claims change or modify, and are all the present invention and contain.
