Embodiment
Below in conjunction with the drawings and specific embodiments, the online upgrading method and apparatus of the power line carrier equipment of embodiments of the invention is described in further detail, but not as a limitation of the invention.
Fig. 1 is the schematic flow sheet of online upgrading method of the power line carrier equipment of embodiments of the invention; Fig. 2 is the configuration diagram of program storage of the power line carrier equipment of embodiments of the invention.In the present invention, power line carrier equipment comprises program storage, as shown in Figure 2, program storage comprises application storage unit (comprising receiving the interrupt routine of normal carrier signal redirect) and upgrading control programs memory cell, with and corresponding interrupt address entrance; Also comprise electrification reset address entrance simultaneously.The online upgrading method of the power line carrier equipment of embodiments of the invention comprises the following steps:
S1: receive and comprise device address after interior starting and upgrading signal, enter interruption;
S2: judge whether the device address of himself conforms to the device address in starting and upgrading signal, if it is exit and interrupt and enter circular wait state execution step S3, if otherwise exit and interrupt and continue the former instruction of execution;
S3: receive and comprise upgrade information after interior online upgrading signal, upgrade according to the upgrade information in online upgrading signal;
S4: whether judgement upgrading completes, if so, execution step S5; If not, return to step S3;
S5: exit circular wait state and restart.
The method of the online upgrading power line carrier equipment software by embodiments of the invention, can in the situation that the strip of paper used for sealing of not sabotage of electrical power equipment or equipment cabinet by remote computer, control and send the electric-power wire communication signal that contains device upgrade software data.Meanwhile, by addressing system, specify one in the on-the-spot all multi-carrier communication apparatus that move to carry out online upgrading, and other carrier equipments are not exerted an influence.
As a kind of improvement, upgrade information comprises new application program and corresponding memory address thereof, and step S3 is specially: new application program is wiped and write to the former bytecode corresponding to memory address in application storage unit.By such improvement, the software of the power carrier equipment in equipment is write with a brush dipped in Chinese ink again, and without reality contact carrier equipment, thereby make the software error reparation at the power carrier equipment of site of deployment, to normal carrier communication system application design no requirement (NR), without adding the part that coordinates online upgrading in the application software in Customer-Demand-Oriented exploitation.
As further improvement, online upgrading signal also comprises device address, step S3 is specially: receive and comprise upgrade information enter interruption after interior online upgrading signal, judge whether the device address of himself conforms to device address in online upgrading signal and/or whether himself is in circular wait state, if it is exit and interrupt and upgrade according to the upgrade information in online upgrading signal, if otherwise exit and interrupt and continue the former instruction of execution.In startup and escalation process, by addressing system, specify one in the on-the-spot all multi-carrier communication apparatus that move to carry out online upgrading, and other carrier equipments are not exerted an influence like this.
As further improving, the implementation that enters interruption can adopt in S1 step, receives after starting and upgrading signal, by jumping to the interrupt address entrance of upgrading control programs, enters interruption; And/or in S3 step, receive after online upgrading signal, by jumping to the interrupt address entrance of upgrading control programs, enter interruption.By the setting of combined with hardware interrupt address entrance, make to debug in escalation process easy, workable.
As another kind, improve, in order further other carrier equipments not to be exerted an influence, to receive, do not comprise device address after interior Restart Signal, when the device address of himself is when device address in Restart Signal conforms to, execution is restarted.
The present invention also provides a kind of power line carrier equipment of the online upgrading method based on power line carrier equipment as above, it is configured to identify electric-power wire communication signal and starting and upgrading signal and the online upgrading signal receiving, and comprising device address at interior Restart Signal, program storage is configured to can bytecode be wiped and be write.Carrier telecommunication of the present invention, can identify two kinds of electric-power wire communication signals, and a kind of is the electric-power wire communication signal of curstomer-oriented application, for normal electricity line carrier communication; Another kind is the electric-power wire communication signal for online upgrading, i.e. starting and upgrading signal and online upgrading signal, and Restart Signal.Both are difference to some extent on signal characteristic, and for example frame synchronization first code sequence is different.Power line carrier equipment can, by control device of the prior art (as writing corresponding control register), be wiped and byte write a part for program storage (as EEPROM or Flash).
Below pass through an embodiment to the power line carrier equipment of embodiments of the invention and online upgrading method thereof.
1), computer sends and comprises device address at the online upgrading power line signal (starting and upgrading signal) of interior online upgrading starting command.All equipment that receives this signal all jumps to upgrading interrupt address entrance and enters interruption, the carrier equipment that meets device address enters a circular wait state, the carrier equipment that does not meet device address directly exits and interrupts the work that continuation is interrupted, thereby unaffected.
2), computer sends and comprises device address at interior online upgrading power line signal (online upgrading signal), wherein comprised the bytecode of new client applications and the address that these bytecodes should be stored in client applications space.All equipment that receives this signal all jumps to upgrading interrupt address entrance and enters interruption, meet the carrier equipment of device address according to the address and the data that receive, the former bytecode of application space is wiped, and rewrite the bytecode of the new procedures receive, and continuing to enter circular wait state. the carrier equipment that does not meet device address directly exits and interrupts continuing the work that interrupted.
3), repeating step 2), until new application program has all been received and completed by carrier equipment to be upgraded, wipe accordingly and rewrite process.
4), computer sends and comprises device address and restart power line signal (Restart Signal) in interior system, the carrier equipment that meets device address is restarted system by stopping feeding the modes such as house dog, and the system application reentering after upgrading is carried out. and other equipment are unaffected.So just completed specifying the on-line software updating of carrier telecommunication.
Compared with prior art, the beneficial effect of power line carrier equipment of the present invention and online upgrading method thereof is:
1, can to device systems operating software, upgrade upgrading by including the power line signal of online upgrading signal.
2, can specify one in the on-the-spot all multi-carrier communication apparatus that move to carry out online upgrading, and other carrier equipments not exerted an influence.
3, to normal carrier communication system application design no requirement (NR), without adding the part that coordinates online upgrading in the application software in Customer-Demand-Oriented exploitation.
Above embodiment is only exemplary embodiment of the present invention, is not used in restriction the present invention, and protection scope of the present invention is defined by the claims.Those skilled in the art can make various modifications or be equal to replacement the present invention in essence of the present invention and protection range, this modification or be equal to replacement and also should be considered as dropping in protection scope of the present invention.
