[0050] According to the first embodiment of the present invention, the present invention claims a safety management method for elevator operation, referring to Figure 1 ,include:

[0051] Acquire attribute information of the elevator to be safely managed, and adopt a corresponding safety management strategy according to the attribute information of the elevator to be safely managed;

[0052] triggering the monitoring sensor of the elevator to be safely managed based on the safety management strategy, and collecting sensing information of the monitoring sensor;

[0053] Performing a first management control on the elevator to be safely managed according to the sensing information and the historical operation data to obtain a first operation state of the elevator to be safely managed;

[0054] Modifying the first operating state based on the building attribute data of the elevator to be safely managed to obtain a second operating state of the elevator to be safely managed;

[0055] The elevator to be safely managed is controlled to operate in a second operating state within a preset period and historical operating data of the elevator to be safely managed is synchronized.

[0056] Among them, the embodiment of the present invention is program-controlled by the elevator installation department according to actual elevator needs.

[0057] Further, the property information of the elevator to be safely managed is obtained, and a corresponding safety management strategy is adopted according to the property information of the elevator to be safely managed, referring to Figure 2 , also includes:

[0058] Acquiring attribute information of an elevator to be safely managed, and determining category information of the elevator to be safely managed based on the attribute information of the elevator to be safely managed;

[0059] Determining a safety management strategy corresponding to the elevator to be safely managed according to the category information of the elevator to be safely managed;

[0060] The key nodes of the elevator to be safely managed are parsed and extracted from the safety management strategy.

[0061] Among them, in this embodiment, the category information of the elevator to be safely managed is handrail type elevator and car type elevator;

[0062] When the category information of the elevator to be safely managed is an escalator, the first safety management strategy is adopted, and the corresponding key node is each step node of the escalator;

[0063] When the category information of the elevator to be safely managed is a car-type elevator, the second safety management strategy is adopted, and the corresponding key node is the stop node on each floor of the car-type elevator.

[0064] Furthermore, the triggering of the monitoring sensor of the elevator to be safely managed based on the safety management strategy and collecting sensing information of the monitoring sensor also includes:

[0065] Determining a set of monitoring sensors corresponding to the elevator to be safely managed according to a safety management policy corresponding to the elevator to be safely managed;

[0066] The sensing information of the monitoring sensor set is collected and the sensing information is prioritized according to the attribute information of the elevator to be safely managed to obtain a monitoring priority scheme.

[0067] Among them, in this embodiment, when the category information of the elevator to be safely managed is an escalator, the first safety management strategy is adopted, and the corresponding key node is each step node of the escalator, it is determined that the monitoring sensor set corresponding to the elevator to be safely managed includes a speed sensor, a fall sensor, and a displacement sensor;

[0068] When the category information of the elevator to be safely managed is a car-type elevator, the second safety management strategy is adopted, and the corresponding key node is the parking node of each floor of the car-type elevator, it is determined that the monitoring sensor set corresponding to the elevator to be safely managed includes a speed sensor, a gravity sensor, and a gas sensor;

[0069] The priority of the sensing information is configured according to the attribute information of the elevator to be safely managed, and is set according to the historical accident information and service life information of the elevator to be safely managed;

[0070] For example, when any relevant risk appears in historical accident information, the sensor category corresponding to the most serious accident is used as the monitoring sensor with the highest priority;

[0071] When the service life of an elevator reaches a preset time, the monitoring priority of each sensor of the elevator to be safely managed is adjusted. The specific order can be set according to the service life of each sensor of the elevator to be safely managed, and the one with the shorter remaining service life has the highest priority.

[0072] Furthermore, the first management control of the elevator to be safely managed is performed based on the sensing information and the historical operation data to obtain the first operation state of the elevator to be safely managed, and further includes:

[0073] Based on the monitoring priority scheme, collecting historical operation data at different times and extracting historical operation attribute information of the historical operation data;

[0074] A first management control is performed on the elevator to be safely managed according to the sensing information and the historical operation attribute information, a first operation attribute value of the elevator to be safely managed is set, and a first operation state of the elevator to be safely managed is obtained.

[0075] Among them, in this embodiment, the specific time of collecting historical operation data is determined according to the sensor with the highest priority in the monitoring priority;

[0076] For example, when the sensor with the highest priority in the monitoring priority of an escalator is the speed sensor, it is necessary to focus on the crowded time. Therefore, the specific collection time of historical operation data is set as 17:00-21:00 on weekdays and 10:00-21:00 on weekends and holidays;

[0077] When the highest priority sensor in the monitoring priority of escalators is the fall sensor, it is necessary to focus on the passage time of the elderly or children. Therefore, the specific collection time of historical operation data is set to 10:00-17:00 on weekdays;

[0078] The historical operation attribute information includes the running speed and running acceleration of handrail elevators at the corresponding time, and the running speed, running acceleration, ventilation status and load-bearing characteristics of car elevators;

[0079] A first management control is performed on the elevator to be safely managed according to the historical operation attribute information, and a first operation attribute value of the elevator to be safely managed is set to an average value of specific historical operation attribute information to obtain a first operation state of the elevator to be safely managed.

[0080] In this embodiment, the first operating state needs to be corrected based on the building attribute data of the elevator to be safely managed to obtain the second operating state of the elevator to be safely managed;

[0081] The building attribute data includes the internal scene of the specific building where the elevator is placed, including the decoration construction status and the internal scene category;

[0082] Take a large-scale integrated shopping mall as an example. The specific elevator to be managed safely is an escalator. When most of the shops on the third floor of the mall are under renovation and construction, the probability of customers visiting this floor decreases. Therefore, it is determined that the speed and acceleration of the elevators on the 2nd and 3rd floors need to be increased in appropriate proportions.

[0083] When most of the stores on the 4th floor of the mall have recently changed their preset cycles, the probability of customers visiting this floor increases. In this case, it is determined that the speed and acceleration of the elevators on the 3rd and 4th floors need to be reduced in appropriate proportions to facilitate customers' browsing.

[0084] When most of the stores on the 5th floor of the mall are toys, the elevator detects that the proportion of children in the real-time crowd exceeds the preset value. At this time, the speed and acceleration of the elevators on the 4th and 5th floors need to be reduced in an appropriate proportion to facilitate browsing by child target customers.

[0085] Further, the controlling the elevator to be safely managed to operate in the second operating state within a preset period and synchronizing the historical operating data of the elevator to be safely managed includes:

[0086] When the elevator to be safely managed is operated in the second operating state within a preset period, the operating state performance information of the elevator to be safely managed is collected in real time;

[0087] The second operating state and operating state performance information of the elevator to be safely managed are synchronously stored in the historical operating data of the elevator to be safely managed.

[0088] According to a second aspect of the present invention, the present invention claims a safety management device for elevator operation, referring to Figure 3 ,include:
