Description
Technical field
The present invention relates to a kind of methods that generating set parallel controller quickly distributes communication id automatically, are applied to generator
Group parallel controller.
Background technique
1, due to Sciences productivity progress, large capacity electrical equipment is more and more, and small power generator group is difficult to meet life
Production demand is powered so more generating sets need to be often together in parallel, together in addition with to power supply reliability and economical operation
Property require, be usually also required to more parallel operation of generator get up use, so generating set it is used in parallel meeting it is more and more.So
It when unit is used in parallel, needs to control it using parallel controller, needs to carry out by communication modes between controller
Data transmission and shared, if ID setting is not right, will cause to communicate ID conflict, lead to data corruption and mistake, can not identify institute
Belong to controller, further result in power distribution and the control of unit Automatic dispatching, so commissioning staff will before carrying out equipment debugging
ID is set, and confirms whether there is identical ID in bus.
2, to solve the above-mentioned problems, later people increase ID collision alert function in parallel module, prevent from being equipped with phase
With ID, if having identical ID if module issue ID collision alert, remind people's parallel system in have ID conflict, need to re-start
ID is set.Although a possibility that identical this solves setting ID, need to increase unit when having unit running in bus
Or maintenance replacement parallel controller, it is possible to which ID has on the unit or the maintenance more ID of parallel controller module and bus newly increased
Conflict will lead to go out ID collision alert using unit in bus in this way, compressor emergency shutdown operation made to lead to power failure accident.
3, later someone has invented one kind and has been randomly assigned ID method: as " a kind of unit parallel controller is randomly assigned ID
Method " the patent No.: 201610775805.2, such method may be implemented when single unit controller puts into communication bus in 0-3S
ID distribution is carried out in time, but it is not due to having arbitration mechanism, when more generator set controllers put into communication bus simultaneously, nothing
Method carries out quickly distribution ID, and is possible to by can not also be distributed for a long time, because sending ID at random, everybody has can
It all can send out ID identical always, and be difficult to obtain the distribution of ID.
Summary of the invention
1, the purpose of the present invention is being directed to the deficiency of currently available technology, so that bus time can be occupied by providing one kind
It is short, without waiting for the time, fast automatic distribution ID can be carried out at any time under any state of bus.
2, the present invention is realized by following technical solution: a kind of fast automatic point of generating set parallel controller
Method with communication ID, this method comprises:
Step 1, when device power, then enter the address ID distribute state；
Step 2, the cpu factory of each equipment are preceding internal provided with the unique code in the whole world 64bit, when equipment enters address distribution
State Shi Huixiang bus issues ID application order, and which includes unique codes；
Step 3, after all devices in bus receive the order that this contains unique code, had the equipment meeting of ID
Issue the respective address ID；
Step 4 without the equipment of the address ID then will record the address ID, while can use the unique code received and oneself
Oneself unique code compares, and the priority distributed if the code of oneself is relatively more preferential can obtain ID distribution, other
Equipment will then wait until the distribution arbitration cycle of next round；
After step 5, preference faciltiy obtain ID, the ID shared by oneself can be issued to bus to make to confirm, while notifying other
The equipment of unallocated ID can enter next ID assignment period；
Step 6 repeats 2-5 step, the ID distribution of multiple equipment can be rapidly completed, into normal operating status.
2. it is internal before the CPU factory of each equipment to be provided with the unique code in the whole world 64bit in step 3 based on above-mentioned, to set
It is standby to carry out providing secondary load condition when automatic distribution ID.
3. ID application order is issued to communication bus when equipment enters address distribution state based on above-mentioned, wherein application life
It include unique code.
4. based on above-mentioned, the equipment of ID is not received after unique codes of other equipment and unique code is compared self, secondary
Carry the priority of ID distribution.
5. based on above-mentioned, each equipment distributes the time to obtaining ID again to secondary carry of ID priority after issuing ID apply order
﹤ 0.01S.
Detailed description of the invention
Fig. 1 is implementation flow chart of the invention；
Specific embodiment
1, logical below that charger of the present invention is described in further detail in conjunction with attached drawing:
The method of the fast automatic distribution communication ID of a kind of generating set parallel controller as shown in Figure 1:, this method comprises:
Step 1, when device power, then enter the address ID distribute state；
Step 2, the cpu factory of each equipment are preceding internal provided with the unique code in the whole world 64bit, when equipment enters address distribution
State Shi Huixiang bus issues ID application order, and which includes unique codes；
Step 3, after all devices in bus receive the order that this contains unique code, had the equipment meeting of ID
Issue the respective address ID；
Step 4 without the equipment of the address ID then will record the address ID, while can use the unique code received and oneself
Oneself unique code compares, and the priority distributed if the code of oneself is relatively more preferential can obtain ID distribution.Other
Equipment will then wait until the distribution arbitration cycle of next round；
After step 5, preference faciltiy obtain ID, the ID shared by oneself can be issued to bus to make to confirm.Notify other simultaneously
The equipment of unallocated ID can enter next ID assignment period；
Step 6 repeats 2-5 step, the ID distribution of multiple equipment can be rapidly completed, into normal operating status.
2, when stating step on the implementation, the unique code in the whole world 64bit is provided with before the CPU of each equipment factory, be equipment into
Row provides secondary load condition when distributing ID automatically.
3, illustrate the time required to when revolving above-mentioned steps in fact: above method controller is communicated with CANBUS to be implemented, and setting is total
Line communication baud rate is 250Kps, then the time of every transmission 1Bit is 1/250000=0.000004 seconds, transmits a byte
The time of (1byte) is 0.000004 × 10=0.00004 seconds, and each CAN data packet shares 8 bytes, so transmission one
Packet time is 0.00004 × 8=0.00032 seconds.3 data packets need to only be received and dispatched by completing ID distribution address, referring to implementation stream
Cheng Tu is to issue ID application order to bus, obtain ID and unique code, the distribution address ID respectively, completes a controller and obtain
The time of ID distribution is 0.00032 × 3=0.00096 seconds, is less than 0.01S, it is believed that controller can be quickly obtained ID points
Match.
