Elevator failure will bring inconvenience to people's travel and affect people's normal life. Elevator dampness or flooding is an important cause of elevator failure. Elevator dampness or flooding may not only cause damage to the equipment at the top or bottom of the elevator, but also cause electrical failures and even cause the elevator to stop operating.

[0003] There are many reasons for elevator flooding, which may be: water accumulation in the garage on rainy days, which backflows into the elevator car or the pit at the bottom of the shaft; the resident's water pipe breaks, and water flows into the shaft, causing the car to be flooded or water to accumulate in the pit, etc. The general reasons for the elevator to be damp are: a small amount of accumulated water flows into the pit along the side wall of the shaft, and the accumulated water cannot be discharged after evaporation in the pit, and accumulates in the pit; the pit is not blown dry after a large amount of accumulated water is discharged; the surface is wet due to continuous rainy days, etc.

[0004] The existing method of dealing with water ingress in elevators is usually to manually inspect the elevator shaft regularly, and then use drainage equipment to drain the water after water ingress is found.

[0050] In the present invention, by adopting the method of selecting sample shafts, the environmental conditions of other elevator shafts in the entire monitoring and management area are judged according to the environmental conditions of the sample shafts.

[0052] In some embodiments, step S5 is also included: the shaft monitoring platform obtains each monitoring management area Weather data from each monitoring management area Weather data from each monitoring area Internal sample well The number of and the frequency of data collection for multiple types of monitoring devices.

[0053] Specifically, for step S1, combined with Figure 2 The monitoring and management area distribution diagram shown in the figure shows that there are usually multiple residences in a property service area. The property service area can be a city or an administrative district, etc. Usually, there are corresponding monitoring and management areas according to the different geographical locations of these residences in the property service area. As Figure 2 As shown in the figure, the multiple residences located in the northwest corner of the property service area are northwest monitoring area B1, the multiple residences located in the southwest corner of the property service area are southwest monitoring area B2, and the multiple residences located in the east of the property service area are east monitoring area B3. Different property service areas will also have different monitoring management areas according to the location of the residences. division.

[0054] Monitoring management area The division is not only based on the different geographical locations of the residences, but also on the climate characteristics and weather change patterns of the residences, and the climate characteristics and weather change patterns can be used as monitoring and management areas. The reference basis for the division is that these climate characteristics and weather change laws are the main factors affecting the elevator shaft environment. The multiple residential buildings in the area are basically in the same climate environment, that is, in the same monitoring and management area. All residential buildings within the area are subject to the same climate characteristics and weather patterns, so that The elevator shafts of some residential buildings were selected as sample shafts. For these sample wells Collect and analyze environmental data, and then use it to judge the entire monitoring management area The environmental conditions of all elevator shafts within the building.

[0055] Specifically, for step S2, combined with Figure 3 The schematic diagram of the elevator shaft shown in FIG. 1 shows an elevator shaft, that is, a sample shaft. Then divide it into car units , Hoistway side wall unit and shaft pit unit The car unit Mainly refers to the elevator car as a whole, the shaft side wall unit Mainly refers to the four side walls of the elevator shaft, the shaft pit unit Mainly refers to the pit at the bottom of the elevator shaft.

[0056] Specifically, in step S2, the multiple types of monitoring equipment used include humidity sensors, liquid level sensors, infrared cameras, water sensors and infrared detectors. These sensors correspond to the environmental data sets collected. Including from the car unit Personnel data inside, car unit Liquid level data in the car unit Water flooding data of the bottom and shaft side wall units Water seepage data, shaft pit unit Humidity data and shaft pit units The liquid level data.

[0057] Corresponding, combined Figure 3-Figure 6 As shown, multiple types of monitoring equipment are used to collect car unit , Hoistway side wall unit and shaft pit unit Environmental data collection , including: in the car unit An infrared detector 1 is installed on the top of the inner wall. A first liquid level sensor 2 is provided at the bottom of the inner wall. A water-sensitive sensor 3 is provided at the bottom of the outer wall, and an infrared detector 1 is used to collect the cabin unit The first liquid level sensor 2 is used to collect the personnel data of the car unit. The first liquid level data in the car unit is collected by the water-sensitive sensor 3. Water immersion data in the car unit The bottom of the outer wall is provided with an infrared camera 4, which is used to The movement of the hoistway side wall unit Take snapshots to obtain the shaft side wall unit Water seepage data; in the shaft pit unit A humidity sensor 5 is provided at the bottom of the shaft pit unit. A second liquid level sensor 6 is provided at the lower part of the side wall of the well pit unit. The third liquid level sensor 7 is arranged at the upper end of the side wall, and the humidity sensor 5 is used to collect the humidity of the well pit unit. Humidity data, the second liquid level sensor 6 and the third liquid level sensor 7 are used to collect the humidity data of the pit unit The second liquid level data and the third liquid level data.

[0058] Furthermore, the sample well Environmental data collection It is installed in the car unit , Hoistway side wall unit and shaft pit unit Environmental data collected by various types of monitoring equipment The environmental data set is collected by various monitoring devices and then transmitted to the well monitoring platform, which analyzes and judges it.

[0059] Specifically, these multi-type monitoring devices can upload data to the data processor in the residence through communication cables or wireless transmission, and the data processor in each residence can then upload the data to each monitoring management area. The cloud server then uploads the data to the shaft monitoring platform. The shaft monitoring platform here mainly refers to a professional service platform for data analysis and alarm linkage. Through this shaft monitoring platform, all elevator shafts in the entire property service area can be monitored and managed, so that each monitoring management area can be understood through this shaft monitoring platform. situation, so as to rationally allocate human and material resources and improve property management efficiency.

[0060] Further, combined with Figure 3-Figure 6 As shown, for steps S3 and S4, the well monitoring platform collects environmental data Analyze and judge to obtain the sample well The real-time environmental report is described in detail.

[0061] Specifically, the alarm terminal in step S3 includes a sample well The sound and light alarm in the property monitoring room corresponding to the residence, the sample well Car unit Internal sound and light alarms and mobile phones of property management personnel of corresponding residences, etc.

[0062] Specifically, the linkage maintenance terminal in step S4 includes a device disposed in the pit unit of the well. Drainage equipment, drying equipment and car units wait.

[0063] First, the unit set in the pit The data collected by the second liquid level sensor 6 and the third liquid level sensor 7 on the side wall are analyzed, such as Figure 4 As shown, the second liquid level sensor 6 and the third liquid level sensor 7 are both arranged in the pit unit of the well. The second liquid level sensor 6 is set at a height H1, which is usually a distance from the bottom pit unit of the well. The third liquid level sensor 7 is set at a height of H2 at the bottom 2cm-3cm of the well. The height H2 is the height of the well pit unit. At the top of the shaft, the second level sensor 6 and the third level sensor 7 only collect trigger signals during the actual collection process, that is, when the shaft bottom pit unit When the liquid level in the well reaches the height H1, the second liquid level sensor 6 generates a trigger signal; When the liquid level in the container reaches the height H2, the third liquid level sensor 7 generates a trigger signal.

[0064] Furthermore, two liquid level sensors can be installed at the same height, that is, two second liquid level sensors 6 are set at the height H1, and two third liquid level sensors 7 are set at the height H2. The two liquid level sensors at the same height are connected in series, and a trigger signal is generated only when the two liquid level sensors at the same height are operated at the same time, so as to prevent some water droplets from splashing onto the liquid level sensor and causing malfunction of the liquid level sensor.

[0065] Specifically, if the shaft monitoring platform only receives the trigger signal of the second liquid level sensor 6, it indicates that the shaft bottom pit unit Water has entered the shaft pit unit The liquid level is higher than height H1 and lower than height H2, and the amount of water entering is not much. At this time, the shaft monitoring platform sends a first-level pit water inflow alarm signal to all alarm terminals. All alarm terminals alarm and link the corresponding shaft pit units at the same time. The drainage equipment in the pit unit is used to drain water until the liquid level is lower than the height H1. The drainage equipment stops working and the drying equipment is used to blow water to the bottom pit unit. Continue to dry. At the same time, the unit installed in the pit The humidity data collected by the humidity sensor 5 is analyzed. The warning humidity value can be set in the shaft monitoring platform. The size of the warning humidity value can be adjusted by the relevant management personnel. The warning humidity value is used as the threshold. The collected humidity data is compared with the warning humidity value. When the humidity data is greater than the warning humidity value, it indicates that the current shaft pit unit is The humidity is high, and there is a risk of corrosion to some metal structural parts inside the elevator shaft. When the humidity data is lower than the warning humidity value, it indicates that the current shaft pit unit Low humidity and no water ingress, no environmental risk. Continue to dry until the humidity data is lower than the warning humidity value, and then the drying equipment stops working.

[0066] If the well monitoring platform receives the trigger signals of the second liquid level sensor 6 and the third liquid level sensor 7 at the same time, it indicates that the sample well The liquid level has exceeded the pit unit , the amount of water inflow is large, at this time the shaft monitoring platform sends a secondary pit water inflow alarm signal to all alarm terminals, all alarm terminals alarm, and link the corresponding shaft pit unit Drainage equipment within and adjacent shaft pit units The drainage equipment in the well is used to drain water until the liquid level is lower than the height H1. The drainage equipment stops working and the drying equipment is used to blow water to the well pit unit. Continue to dry until the humidity data is lower than the warning humidity value, and then the drying device stops working.

[0067] If the shaft monitoring platform does not receive the trigger signal of the second liquid level sensor 6 and the third liquid level sensor 7, but the humidity data collected by the humidity sensor is greater than the warning humidity value, it indicates that the shaft pit unit There is no water ingress, but it is quite humid, which poses a safety hazard. At this time, the shaft monitoring platform sends an alarm signal to the mobile phone of the property management personnel, and links the drying equipment to the shaft pit unit. Continue to dry until the humidity data is lower than the warning humidity value, and then the drying equipment stops working.

[0068] If the shaft monitoring platform does not receive the trigger signal of the second liquid level sensor 6 and the third liquid level sensor 7, and the humidity data collected by the humidity sensor is less than the warning humidity value, it indicates that the shaft bottom pit unit The environment meets the standards and there are no safety hazards.

[0069] It should be noted that when the shaft pit unit When the liquid level in the car reaches the height H2, it will not affect the car unit. Impact, car unit When running to the bottom, the distance from the pit unit There must be at least one space no smaller than 0.50m×0.60m×1.0m.

[0070] Further, such as Figure 5 As shown, it is arranged in the car unit Infrared cameras at the bottom of the outer wall 4 pairs of shaft side wall units Take a snapshot and upload the captured image information to the shaft monitoring platform, which analyzes and judges the image information and finally sends out an alarm signal.

[0071] Specifically, first, the infrared camera 4 is connected to the car unit The movement of the hoistway side wall unit The four side walls are connected and captured, and the captured image information is uploaded to the shaft monitoring platform;

[0072] The shaft monitoring platform identifies the liquid traces in the image information to obtain an identification pattern;

[0073] According to the recognition pattern, a multidimensional feature vector is formed, each dimension of which represents the feature of the corresponding part of the above recognition image. The feature extraction can adopt the HOG feature extraction algorithm. These features include the direction density and grayscale of the edge, etc., which will not be repeated here;

[0074] The multidimensional feature vector is compared with the standard feature vector of the predetermined graphic model, wherein the predetermined graphic model is obtained by pre-shooting multiple images with liquid traces by the infrared camera 4, and the standard feature vector is obtained by pre-identifying the predetermined graphic model by the shaft monitoring platform, wherein the liquid traces include water droplets, water drops and water flow, wherein the water droplets here refer to static and dispersed water droplets, water droplets refer to multiple water droplets that flow according to a certain rule and have intervals between each other, and water flow refers to liquid that flows according to a certain rule and has no intervals between each other. Correspondingly, there are three types of standard feature vectors, namely, water drop feature vector, water drop feature vector and water flow feature vector. When comparing, the multidimensional feature vector is compared with the above three standard feature vectors respectively. When the multidimensional test vector matches the water drop feature vector, it indicates that water droplets may appear in the shaft side wall unit; when the multidimensional test vector matches the water drop feature vector, it indicates that water droplets may appear in the shaft side wall unit; when the multidimensional test vector matches the water flow feature vector, it indicates that water flow may appear in the shaft side wall unit.

[0075] When the shaft side wall unit When water drops appear, the humidity data collected by the humidity sensor 5 is analyzed. If the humidity data is greater than the warning humidity value, the well pit unit is ventilated according to the above method. Perform maintenance; if the humidity data is less than the warning humidity value, it indicates that the shaft side wall unit The water droplets that appear do not exist on the shaft pit unit There is no need to raise an alarm for potential hazards, just wait until it dries naturally.

[0076] When the shaft side wall unit When water drops appear, the shaft monitoring platform sends a first-level side wall water ingress alarm signal to the corresponding manager's mobile phone, reminding the manager to promptly investigate the cause of water ingress and monitor the shaft pit unit in real time. The humidity sensor 5, the second liquid level sensor 6 and the third liquid level sensor 7 collect environmental data to prepare for linkage maintenance.

[0077] When the shaft side wall unit When water flows, the shaft monitoring platform sends a secondary side wall water inflow alarm signal to all alarm terminals. The alarm terminals sound an alarm, reminding management personnel to promptly investigate the cause of water inflow, remind passengers to pay attention to the elevator operation status, and monitor the shaft pit unit in real time. The humidity sensor 5, the second liquid level sensor 6 and the third liquid level sensor 7 collect environmental data to prepare for linkage maintenance.

[0078] Further, combined with Figure 5 and Figure 6 As shown, it is arranged in the car unit Water-sensitive sensors at the bottom of the outer wall 3 pairs of car units Specifically, when the water level in the elevator shaft exceeds the water-sensitive sensor 3, the water-sensitive sensor 3 generates a trigger signal and transmits the trigger signal to the shaft monitoring platform. The shaft monitoring platform sends a control signal to the elevator controller in the corresponding residence, and the elevator controller controls the car unit. Rise to the designated floor, which can be pre-set by the management personnel in the shaft monitoring platform, usually the 3rd or 4th floor.

[0079] Further, combined with Figure 5 and Figure 6 As shown, in some embodiments, the car unit is provided The infrared detector 1 at the top of the inner wall detects the car unit Is there a passenger in the car? If there are passengers in the car, the car unit is controlled After ascending to the nearest floor, open the car unit The car door of the elevator is opened and an alarm signal is sent to the corresponding car unit. The sound and light alarm inside the car unit ; If the car unit If there are no passengers in the elevator, the car unit is directly controlled. Just go up to the designated floor.

[0080] In some embodiments, in combination Figure 5 and Figure 6 As shown, it is arranged in the car unit The first liquid level sensor on the inner wall 2 pairs of car units The water ingress inside is monitored. Specifically, the first liquid level sensor 2 is arranged in the car unit. On the inner side wall, the first liquid level sensor 2 is set at a height H3, which is usually the distance from the car unit 2cm-3cm from the bottom, when the car unit When water enters the elevator car and the water level reaches the height H3, the first liquid level sensor 2 is triggered and transmits the trigger signal to the shaft monitoring platform. The shaft monitoring platform sends a water ingress alarm signal to all alarm terminals, and combines the passenger information collected by the infrared detector 1. If the elevator unit If there are passengers in the car, open the car door at the nearest floor; if the car unit If there are no passengers in the car, the car door is always closed and the car unit is controlled. Descend to the lowest level.

[0081] Specifically, for step S4, the weather data can be the monitoring management area The weather changes within a monitoring cycle, which can be one week or half a month, can be adjusted based on the expected monitoring frequency. The first sample threshold and the second sample threshold are pre-set in the shaft monitoring platform. The first sample threshold and the second sample threshold can also be adjusted according to the different monitoring frequencies. For example, the first sample threshold can be that the number of rainy days in a monitoring cycle is greater than the total number of days in the monitoring cycle, and the second sample threshold can be that the number of rainy days in a monitoring cycle is equal to the total number of days in the monitoring cycle. When the monitoring management area When the weather data reaches the first sample threshold, it will be The number of sample wells selected in the monitoring management area is adjusted to twice the original number; When the weather data reaches the second sample threshold, the shaft monitoring platform will monitor the management area The multi-type monitoring devices corresponding to all elevator shafts in the system are sampled to realize the monitoring of the elevator shafts.

[0082] In addition, whenever there is a danger in the environment inside the elevator shaft, the shaft monitoring platform controls the alarm terminal to alarm according to the real-time environmental report, indicating that the sample shaft Monitoring and management area Other elevator shafts may also be dangerous, so the corresponding monitoring management area will also be adjusted The sample wells sampled within The number of to exclude the monitoring management area The specific number of additional samples can be pre-set on the shaft monitoring platform to identify potential safety hazards in other elevator shafts. The number of additional samples can be increased by multiples of the original number of samples, or the number of additional samples can be increased for the entire monitoring management area. All elevator shafts in the facility are monitored.

[0083] Based on the same inventive concept, Figure 7 and Figure 8 As shown, the present invention also discloses an elevator shaft environment monitoring system, comprising

[0084] A shaft monitoring platform 10 is used to centrally monitor and manage the environment of multiple elevator shafts in a wide area;

[0085] The environmental monitoring module 20 is used to collect the liquid level data and humidity data of the pit of each elevator shaft, the water seepage data of the side wall of the elevator shaft, and the water infiltration data, liquid level data and personnel data of the elevator car in the elevator shaft;

[0086] The data transmission module 30 is used to transmit the liquid level data, humidity data, water seepage data, water immersion data and personnel data collected by the environment monitoring module 20 to the well monitoring platform 10;

[0087] The alarm module 40 is used to respond to the control of the well monitoring platform 10 and send out an alarm signal.

[0088] Each elevator shaft is equipped with an environmental monitoring module 20, a data transmission module 30 and an alarm module 40. The environmental monitoring module 20 located in each elevator shaft collects environmental data of the pit, side walls and elevator cars of each elevator shaft, wherein the environmental monitoring module 20 is composed of various types of sensors; the environmental data collected by the environmental monitoring module 20 is uploaded to the data transmission module 30, and the data transmission module 30 transmits various environmental data to the shaft monitoring platform 10. The shaft monitoring platform 10 centrally monitors the environmental data and analyzes and judges the environmental data. When there is an environmental hazard in the elevator shaft, the alarm module 40 is controlled by the data transmission module 30 to send an alarm signal. The shaft monitoring platform 10 can monitor multiple elevator shafts at the same time, which reduces labor costs, is more efficient, and is convenient for centralized management by management personnel.

[0089] Each elevator shaft corresponds to an environmental monitoring module 20. The shaft monitoring platform 10 can be divided into different monitoring and management areas according to the geographical locations of the elevator shafts. There are multiple elevator shafts in one monitoring and management area. The environmental data of the elevator shafts in one monitoring and management area is collected by sampling, and then the environmental conditions of other elevator shafts in the entire monitoring and management area are judged based on the sampled elevator shafts, thereby reducing the monitoring pressure of the shaft monitoring platform 10 and reducing the energy consumption cost of multiple environmental monitoring modules 20 for collecting environmental data of multiple elevator shafts respectively.

[0090] In some embodiments, Figure 7 and Figure 8 As shown, it also includes a linkage maintenance terminal 50, which is used to respond to the control of the well monitoring platform 10 and maintain the environment of the elevator well to eliminate the dangers and hidden dangers of the elevator well. The linkage maintenance terminal 50 can automatically maintain the environment of the elevator well when there is danger in the elevator well, so as to quickly eliminate potential dangers and hidden dangers. Compared with manual maintenance, the response speed is faster and the effect is better.

[0091] In some embodiments, Figure 8 As shown, the linkage maintenance terminal 50 includes a drainage device 501, a drying device 502 and a car controller 503. The drainage device 501 is used to drain the water in the pit, and the drying device 502 is used to blow air into the pit to keep it dry; the car controller 503 is used to control the movement of the elevator car. When water accumulates in the pit, the drainage device 501 automatically opens to drain the water in the pit; after the water is drained, the drying device 502 blows air into the pit again to prevent the humid environment of the pit from affecting the metal equipment in the elevator shaft; when an unexpected situation occurs in the drainage device 501 and the water is not drained in time, resulting in the water rising continuously and contacting the bottom of the elevator car, the car controller 503 automatically controls the elevator car to move to the upper floor to prevent the water from flooding into the elevator car, which is safer.

[0092] It can be seen that the present invention discloses a method for monitoring the environment of multiple elevator shafts in a wide area.

[0093] The system divides and determines different monitoring and management areas according to the different geographical locations of the residences where the elevator shafts are located. Sample shafts are selected in the monitoring and management areas, and the environmental data sets of the car units, shaft sidewall units and shaft pit units of the sample shafts are collected using multiple types of monitoring equipment. The shaft monitoring platform analyzes and judges the environmental data sets to obtain real-time environmental reports of the sample shafts. When the sample shafts are in environmental danger, the alarm terminal is controlled to alarm and the number of sample shafts sampled in the corresponding monitoring and management area is adjusted. By selecting sample shafts, the environmental conditions of other elevator shafts in the entire monitoring and management area are judged according to the environmental conditions of the sample shafts. When monitoring the environments of multiple elevator shafts in a wide area, the shaft monitoring platform can realize centralized management of multiple elevator shafts, which is more efficient and has lower monitoring costs. In addition, the number of sample shafts can be adjusted according to feedback, ensuring the reliability of monitoring.

Any equivalent structural transformations made using the contents of the present invention's specification and drawings, or directly or indirectly applied in other related technical fields, are also included in the patent protection scope of the present invention.
