Referring to fig. 1, an embodiment of the present invention provides an elevator monitoring method based on a night imaging technology, where the monitoring method includes:
s10) acquiring normal position information of a moving part of the elevator;
s20) acquiring operation position monitoring information of the moving part, wherein the operation position monitoring information includes daytime position monitoring information and nighttime position monitoring information;
s30) analyzing the use state of the moving part based on the normal position information and the running position monitoring information to obtain an analysis result;
s40) if the analysis result is that the moving part is abnormal, generating and feeding back corresponding abnormal alarm information.
In the embodiment of the present invention, preferably, the moving member includes, but is not limited to, at least one of a wire rope, a traction machine, a rope turning wheel, a guide shoe, and a safety gear.
In an embodiment of the present invention, the acquiring normal position information of a moving part of an elevator includes: judging whether the ambient brightness of the current environment is greater than a preset brightness threshold value or not; if the environmental brightness of the current environment is greater than the preset brightness threshold, judging whether the moving part normally operates; if the moving part normally operates, acquiring daytime moving image information of the moving part; generating normal position information of the moving part based on the daytime moving image information.
In one possible embodiment, the elevator control system first acquires normal position information of the moving part of the elevator during normal operation before the elevator is used normally. For example, an image acquisition device (e.g., a camera) based on a night imaging technology is installed in a machine room and/or a hoistway of an elevator, and image information of a moving part is acquired in an environment with strong illumination intensity.
In the collecting process, the image collecting device or the elevator control system firstly judges whether the ambient brightness of the current environment is greater than a preset brightness threshold value, for example, the elevator control system can detect the ambient brightness near the moving component through the brightness detecting device arranged near the moving component, if the ambient brightness of the current environment is greater than the preset brightness threshold value, whether the moving component normally runs is judged, for example, whether each moving component normally runs can be determined by acquiring the state information of each moving component in the elevator control system, if each moving component or the currently monitored moving component normally runs, the day moving image information of the moving component in the running process is acquired, for example, technicians respectively drive the elevator to run under the conditions of no load, half load and full load, and the day moving image information of the elevator in the running process is collected by the image collecting device, and uploaded to the elevator control system.
It should be noted that, the step of obtaining the normal position information of the moving component of the elevator may be performed at any time during the use of the elevator, and should not be limited to the time before the elevator normally runs, and the above technical effect can be achieved, so as to solve the above technical problem, and therefore, the step of obtaining the normal position information of the moving component of the elevator also belongs to the protection scope of the present invention, and is not described herein in detail.
In the embodiment of the invention, the normal position information of each moving part in the running process is obtained under the normal illumination intensity and the normal working state of the elevator, so that accurate comparison information is provided for the subsequent automatic analysis of each moving part, and the elevator control system can directly compare the image information acquired in real time during the running of the elevator with the normal position information without performing additional data conversion or data analysis, thereby reducing the operation complexity of the elevator control system, improving the analysis accuracy, reducing the response time of faults and improving the use safety of the elevator.
In an embodiment of the present invention, the acquiring the operation position monitoring information of the moving component includes: judging whether the ambient brightness is smaller than the preset brightness limit value or not; if the ambient brightness is greater than or equal to the preset brightness limit value, acquiring daytime moving image information of the moving part, and generating corresponding daytime position monitoring information based on the daytime moving image information; if the ambient brightness is smaller than the preset brightness limit value, acquiring night motion image information of the motion part, and generating corresponding night position monitoring information based on the night motion image information; and generating the operation position monitoring information of the moving part based on the daytime position monitoring information and the night position monitoring information.
In one possible embodiment, the elevator control system monitors each moving part in real time during operation after acquiring the normal position information of the moving part. Since the illumination intensity of most areas in the elevator machine room or the hoistway is low, it is first determined whether the ambient brightness around the moving part is less than a preset brightness limit. For example, in the process of monitoring the position of the guide wheel, the elevator control system firstly judges whether the ambient brightness near the guide wheel is smaller than a preset brightness limit value or not, and finds that the ambient brightness is larger than the preset brightness limit value, so that the daytime moving image information of the guide wheel is directly acquired through the image acquisition device, corresponding daytime position monitoring information is generated according to the daytime moving image information, for example, the daytime moving image information within 2s of a certain time period is identified to acquire vibration information of the guide wheel, and then the corresponding daytime position monitoring information is generated according to the vibration information.
In another possible embodiment, the elevator control system monitors the position of the traction machine in real time, because the traction machine is located in the machine room, and the ambient brightness in the machine room is smaller than the preset brightness limit value, the image acquisition device acquires the traction machine image in the machine room in real time according to the preset night imaging technology, analyzes the acquired night motion image information of the traction machine to generate corresponding night position monitoring information, and then the elevator control system automatically combines the acquired day position monitoring information and the night position monitoring information to obtain the running position monitoring information of the moving part.
In the embodiment of the invention, by adopting the image acquisition device based on the night imaging technology, the elevator control system can directly monitor the position of the moving part on the basis of ensuring the monitoring accuracy without being influenced by the ambient brightness, and obtain a direct rather than auxiliary monitoring result, thereby greatly improving the monitoring accuracy of the elevator.
Further, in an embodiment of the present invention, the analyzing the use state of the moving component based on the normal position information and the operation position monitoring information to obtain an analysis result includes: comparing the running position monitoring information with the normal position information; judging whether the running position monitoring information has an abnormal deviation value of which the deviation from the normal position information is greater than a preset deviation threshold value; if the abnormal deviation value exists in the running position monitoring information, obtaining a name of the moving part corresponding to the abnormal deviation value, and taking the name of the moving part, the abnormal deviation value and the abnormal use of the moving part as an analysis result.
In a possible embodiment, after acquiring the running position monitoring information of the steel wire rope, the elevator control system compares the running position monitoring information with the normal running position information of the steel wire rope to obtain a deviation value (for example, the deviation value is 2cm) of the steel wire rope from a normal running position in the use process, and further determines whether the deviation value is greater than a preset deviation threshold value (for example, the preset deviation threshold value is 1.8cm), and finds that the deviation value is greater than the preset deviation threshold value, so that the elevator control system immediately takes "abnormal component is the steel wire rope", "abnormal deviation value is 2 cm", and "abnormal use of the steel wire rope" as analysis.
Further, after the analysis result is obtained, because the analysis result determines that the steel wire rope is abnormal in use, the elevator control system immediately generates steel wire rope abnormal alarm information and feeds the information back to relevant technical personnel, for example, the steel wire rope abnormal alarm information is immediately fed back to the technical personnel through a wireless transmission device, so that the technical personnel is prompted to take corresponding maintenance or repair operation in time.
In the embodiment of the invention, the image acquisition device based on the night imaging technology is adopted to directly monitor and analyze the moving parts in the elevator machine room and/or the shaft, and the elevator control system can directly perform safety analysis according to the actual use condition of each moving part.
