Abstract
The invention discloses an automatic recognition method for an overhaul running state of an elevator. The method comprises the following steps of: detecting current or power variation of a main circuit of the elevator and judging whether the elevator is in the overhaul running state according to the detected current or power variation; and triggering a remote data transmission function and recording data of time and current for occurring the overhaul running state by performing remote real-time monitoring on the elevator. By adopting the method, the current variation condition of a main circuit of the elevator can be accurately analyzed, the overhaul running state is more reliably and timely judged, a working state of maintenance is remotely and dynamically monitored, the automation degree and the accuracy are high, and the efficiency is favorably increased and the labor investment is favorably reduced.
Description
Technical field
The present invention relates to the elevator field, relate in particular to a kind of elevator inspection travel state identification method.
Background technology
At present, in order to strengthen the security control of elevator and supervisory to the service work quality to be needed and carry out the technical study of identification automatically of elevator inspection travel state pointedly.The existing technology in elevator field does not comprise the recognition methods of elevator inspection travel state, lacks the possibility of repair and maintenance reliably being traced to the source by technological means.
Summary of the invention

Description of drawings
Fig. 1 is an elevator inspection travel state automatic identifying method diagram of circuit;
Fig. 2 is an elevator inspection travel state automatic identifying method particular flow sheet.
The specific embodiment
For making the purpose, technical solutions and advantages of the present invention clearer, embodiment of the present invention is described further in detail below in conjunction with accompanying drawing:
Present embodiment provides a kind of elevator inspection travel state automatic identifying method, and this method comprises:
Step 20 triggers the remote data transmission function, and by elevator being carried out remote real time monitoring, the time that record inspection travel state occurs and the data of electric current.
Elevator inspection travel state is divided into starting and moves, travels at the uniform speed, runs slowly etc., and when stopping at the uniform velocity state, main circuit current remains unchanged substantially, such as the inspecting state electric current about 4.5A, various types of elevator inspecting state electric current differences.
Said method specifically may further comprise the steps:
Holding current during 101 detection inspection travel states, apparatus for initializing, and set initiation parameter.
102 learn to adjust automatically, determine a pulsation-free aviation value promptly: the inspecting state current threshold.
103 detect elevator main circuit current changing value in real time.
104 judge whether current detection value approaches in inspecting state current threshold ± 5% scope, and after all be in inspecting state current threshold ± 5% scope in 1 second the sense cycle; If judge to satisfy condition that then execution in step 105.
Above-mentioned mode of learning can pass through artificial or pass through inspecting state current threshold of system's self study mode automatic setting.After installing at elevator, holding current when detecting the inspection travel state, apparatus for initializing, automatically learn to adjust, determine that a stable aviation value is the inspecting state current threshold, wherein the inspecting state current threshold can need to prove for a value among 7.5A, 5.0A, the 4.5A, can come correspondence to determine according to different elevator type in the practical application of inspecting state current threshold, be not limited to the occurrence that present embodiment is enumerated.
When elevator is in the state that travels at the uniform speed of inspection travel state, its main circuit current value is in a stable aviation value substantially, and the time ratio that the state of traveling at the uniform speed accounts for the inspection travel state is bigger, the time of promptly keeping is longer, present embodiment is exactly to judge that whether the current value of elevator power circuit is in inspecting state current threshold ± 5% scope that sets up on their own or self study is set, and after all be in inspecting state threshold value ± 5% scope in one second the sense cycle, if show that then elevator is in the inspection travel state.The electric current of power circuit is 20A during such as the elevator normal operation, when being in the inspection travel state, main circuit current is stabilized in about 5A, and after at least 1 second in remain on the inspecting state threshold value ± 5% scope, judge when satisfying these two conditions that elevator is in the inspection travel state.
The above only is preferred embodiment of the present invention, and is in order to restriction the present invention, within the spirit and principles in the present invention not all, any modification of being done, is equal to replacement, improvement etc., all should be included within protection scope of the present invention.
