In another preferred embodiment, described step (3), be specially: described digital control system changes to idle condition with system's stop means from lock-out state, and described step (6) is specially: described digital control system changes to lock-out state with system's stop means from idle condition.
In a kind of further preferred embodiment, the digital control system in the described step (7) is abandoned this manual stepless control signal, is specially: described digital control system should manual stepless control signal be set to invalid.
In an application of the invention, the present invention is based on user's operation of using the automatic spacing release function, provide a kind of advantages of simplicity and high efficiency spacing automatic method for releasing.Because spacing automatic release is only used under the manual continuous function in digital control system, so manually adding a submodule in the continuous function module among the present invention, as shown in Figure 3, this submodule is accepted the manually continuously input of user to digital control system.When spacing, spacing if user's manual continued operation continues to cause, the then not operation of process user and provide prompting; If user's manual continued operation does not produce spacing or removes existing spacingly, then user's operation is passed to the kernel of digital control system, and at after once manually continued operation finishes of user, the lock-out state of retrieval system.Whole submodule only uses the spacing port value of hardware and the interface operation content of digital control system.
Therefore, the present invention's complexity and workload in realization only is equivalent to carry out the very little part that spacing automatic release is handled in kernel, and faster to user's operation response, and gives the upper strata processing continuing spacing work, saved system overhead.The present invention has been also from having found the user demand of spacing automatic release function in essence, and designs at this demand, is the most direct implementation of spacing automatic release function.
In practical application of the present invention, the spacing automatic release function after the simplification is a subfunction of manual continuous function, no longer is main functional modules in the digital control system kernel.Under the spacing alarm state, whole digital control system user can only use manual continuous function controller bed motion.Based on this physical condition, under digital control system limitation locking state, utilize this method manual continued operation processing procedure as shown in Figure 4, it specifically may further comprise the steps:
The first step, user make manual continued operation on the interface, the background process logic of system user interbedded formation can receive this operation, and judges whether the spacing pairing spacing port that this operation may cause has signal;
Second step, if signal is arranged, show that the axle motion due to the current operation still can be limited, then send prompting to the user interactions layer, illustrative system is in spacing state, and current operation is changed to invalid;
The 3rd step, if no signal, show that current operation can be not limited, then remove the lock-out state of current system, carry out the manual continued operation of this step, treat that operation finishes, the lock-out state that the system that returns is previous prepares to receive user's input next time.
The lock-out state of deactivation system in the above-mentioned steps three is to use condition managing mechanism in the digital control system to realize.The system that unlocks is only open to current manual continued operation, so can not cause the situation of system state confusion to take place.
Adopted the method that realizes spacing automatic release function in the digital control system of this invention, under its spacing state, digital control system is only when receiving manual stepless control signal, judge whether this signal is limited by the spacing release submodule in the manual stepless control module, if it is not spacing, then release is spacing automatically, carries out this manual stepless control signal, recovers spacing state then.Owing to this method fully at the reason of spacing generation and release, only when receiving manual stepless control signal, spacing the judging of release to whether automatically, therefore it can effectively reduce system kernel data processing work amount, promote the overall data process performance of digital control system, and the method for the spacing automatic release function of realization of the present invention is swift in response, and uses easyly, and range of application is comparatively extensive.
In this instructions, the present invention is described with reference to its certain embodiments.But, still can make various modifications and conversion obviously and not deviate from the spirit and scope of the present invention.Therefore, instructions and accompanying drawing are regarded in an illustrative, rather than a restrictive.
