Background technology
Present communication product is realized jointly by hardware and software.Because the designing and developing in the process of product, paid attention to functional, security, stability and maintainable high-quality requirement to hardware, the relative software of the probability that makes hardware break down after batch process is little.Because software itself always has problem unresolved when the development and Design of software, and the maintenance of software and upgrading also can be introduced new problem.Therefore, a kind of measure of product needed can make its when operation occurring can carrying out self-regeneration when wrong, return to initial optimum condition after the initialization.
At this problem, if product mistake occurs when operation, prior art provides following two kinds of solutions.
Wherein, first kind of run-time error solution be by software make master cpu (central processing unit) thus producing reseting controling signal makes master cpu (central processing unit) reset, then master cpu (central processing unit) be configured again again read, a series of actions that power on such as port initialization, so just from original run-time error, return to initial state.The characteristics of this method are that product is kept power supply always; Except that master cpu (central processing unit), other processor and chip do not reset.
Second kind of run-time error solution is to occur when wrong manually product being operated by operating personnel when product moves resetting, and realizes the following electricity of product and powers on.The characteristics of this scheme are: product itself need not increase hardware, software cost; Finish corresponding operating by operating personnel.
In above-mentioned first kind of run-time error solution, reset signal is provided by master cpu (central processing unit), and reset time is uncontrollable; Product keeps power supply in reseting procedure, can not realize pure hardware reset; The back product running status that resets is undesired, needs repeatedly reset operation.
In above-mentioned second kind of solution about run-time error, reset operation is finished by operating personnel, needs to increase human cost; The promptness of fault processing is not enough; Because the 26S Proteasome Structure and Function difference of different product is difficult to realize in some products; Do not meet the Long-distance Control of industry, the demand for development of controlling automatically.
Summary of the invention
The embodiment of the invention provides the control method that resets, device and system, can the Long-distance Control mode realize resetting of product and self-regeneration, and realize the robotization of operating process.
On the one hand, provide a kind of control method that resets, received control signal, replied a signal by cable and export to the product power supply under producing, made under the product and reply the position by cable from the product monitoring client.
On the other hand, provide a kind of repositioning control device, comprised reset signal generating circuit, described reset signal generating circuit is used to receive the control signal from the product monitoring client, replies a signal by cable and exports to the product power supply under producing.
Again on the one hand, provide a kind of reset controlling system, replied a control module comprising under by cable, replied a control module by cable described time to link to each other with product monitoring module and product power module in the mode that can communicate by letter,
Described product monitoring module is used for replying a control module output products monitoring client control signal by cable under described when the product run-time error.
Reply a control module under described by cable and be used to receive described product monitoring client control signal, reply a control signal by cable under producing, export to described product power module.
Described product power module is used to receive replies a control signal by cable under described, stops the power supply to product, so that reply the position by cable under the product.
The embodiment of the invention has realized the following position of replying by cable of product, has avoided personnel's participation when realizing the self-regeneration of product run-time error, has realized the robotization of operating process; Have very big versatility, in product, use and carry out corresponding parameter adjustment and get final product; Do not need the product internal circuit is done extra process the harmful effect of having avoided internal circuit hardware and software extra process to cause.
