[0042] The following is a description of the implementation of the present application by specific specific embodiments. People familiar with the technology can easily understand other advantages and effects of the present application from the contents disclosed in this specification. Obviously, the described embodiments are part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in the field without creative work are within the scope of protection of the present application.

[0043] In addition, the technical features involved in the different embodiments of the present application described below can be combined with each other as long as they do not conflict with each other.

[0044] like Figure 1 As shown, an embodiment of the present invention discloses a data collection and analysis method for a wire rope elevator weighing sensor, the method comprising the following steps:

[0045] When an elevator door opening instruction is received, a target elevator door is determined according to the elevator door opening instruction; wherein the target elevator door is any elevator door configured in the elevator shaft where the wire rope elevator is located;

[0046] Sending a first control instruction to a camera associated with the target elevator door, receiving first area image data corresponding to the target elevator door fed back by the camera, and identifying a plurality of elevator objects and their corresponding elevator feature information from the first area image data;

[0047] Sending a second control instruction to the first weighing sensor according to each of the elevator riding characteristic information, and receiving a plurality of first weighing data fed back by the first weighing sensor, and receiving second weighing data fed back by the second weighing sensor; wherein the first weighing sensor is arranged in the passage area of ​​the target elevator door entering the wire rope elevator, and the second weighing sensor is arranged in the wire rope elevator;

[0048] Whether the wire rope elevator has an overload risk is determined according to the first weighing data and the second weighing data, and an overload warning is issued when it is determined that the wire rope elevator has an overload risk.

[0049] In this embodiment, refer to Figure 2The present invention improves the weighing system of the traditional wire rope elevator. In addition to arranging the second weighing sensor in the wire rope elevator, the present invention also arranges the first weighing sensor in the passage area entering the wire rope elevator from the elevator door. Therefore, the weight of the person to be on the elevator is predicted by the first weighing sensor. At the same time, the weight that the elevator has carried at this time is detected by the second weighing sensor arranged in the elevator. According to the carried weight and the safe carrying weight, the remaining carrying weight that the elevator can receive for the person to enter the target elevator door can be calculated, and an early warning can be issued in time when an overload is determined. Therefore, the scheme of the present invention realizes the prediction of the weight of the person to be on the elevator and timely overload alarm by arranging weighing sensors in the elevator and in the elevator entrance passage area outside the elevator car door, which effectively reduces the probability of damage to the wire rope elevator caused by the alarm being issued only after the person has entered the elevator.

[0050] It should be noted that the first weighing sensor and the second weighing sensor preferably use pressure-sensitive weighing sensors, which are pre-installed in the corresponding grooves, and the surface is covered with a cover plate that is connected to the pressure-sensitive weighing sensor and can move up and down. When a person or object passes through the cover plate, the cover plate will drop. After the cover plate drops to a certain extent, it will generate pressure on the pressure-sensitive weighing sensor, thereby realizing the detection of gravity. Of course, weighing sensors based on other principles can also be selected, and the present invention is not limited thereto.

[0051] Optionally, sending a first control instruction to a camera associated with the target elevator door comprises:

[0052] Obtain a node timing table that can characterize the running state of the elevator, and calculate the remaining time to the next elevator stop and door opening node in the node timing table according to the real-time running speed of the wire rope elevator and the preset stop time;

[0053] When the remaining time is less than the remaining time threshold, the first control instruction is generated and sent to the camera associated with the target elevator door.

[0054] In this embodiment, during the operation of the elevator, a node timing table is formulated in real time according to the elevator signals sent by the elevator buttons ("↑" button, "↓" button) arranged at the elevator door of each floor and the preset elevator operation logic, which is used to characterize the next stop and door opening plan of the wire rope elevator. The next stop and door opening node can be determined according to the node timing table. Since the distance between the stop points of each floor is known in advance, the remaining time to the next stop and door opening node can be calculated according to the real-time operation speed of the wire rope elevator and the preset stop time (fixed value) and the distance between adjacent stop points. When the remaining time reaches the remaining time threshold, the generation of the first control instruction will be triggered. Cameras are arranged at the height of the elevator entrance area on each floor. After receiving the aforementioned first control instruction, the camera will capture the real-life image of the object to be boarded in the elevator entrance area.

[0055] Optionally, the remaining time threshold is determined in the following manner:

[0056] When the wire rope elevator runs to the previous elevator stop and door opening node adjacent to the next elevator stop and door opening node in the node timing table, a third control instruction is generated and sent to the camera, and second area image data fed back by the camera is received;

[0057] The image data of the second area is roughly extracted to obtain the number of passengers, and the remaining time threshold is calculated based on the number of passengers and the corresponding positive correlation function.

[0058] In this embodiment, when there are more objects waiting to take the elevator at the next elevator stop and door opening node, the more difficult it is to identify a number of elevator objects and their corresponding elevator feature information from the first area image data, and the corresponding time consumption is longer, so it is necessary to generate and send the first control instruction in advance. In this regard, when the wire rope elevator runs to the previous elevator stop and door opening node adjacent to the next elevator stop and door opening node (that is, the wire rope elevator first runs to the adjacent previous elevator stop and door opening node, and then runs to the next elevator stop and door opening node), that is, when it runs to the previous node of the next elevator stop and door opening node, the third control instruction is sent to the camera in advance, and the camera feeds back the second area image data of the next elevator stop and door opening node. The number of elevator objects at a elevator stop and door opening node can be roughly obtained by the rough extraction algorithm, and the remaining time threshold is calculated according to the number of elevator objects and the corresponding positive correlation function. It can be seen that the more the number of elevator objects, the longer the corresponding remaining time threshold, that is, the earlier the first control instruction is generated, and vice versa, the later the first control instruction is generated. The positive correlation function can be y=kx, where k is the correction coefficient, x is the number of passengers, and k is the conversion coefficient; multiplying the correction coefficient k calculated above by the preset remaining time threshold will give a new remaining time threshold.

[0059] It should be noted that the above-mentioned rough extraction is compared with the precise extraction, that is, only a simple connected domain segmentation is performed on the elevator objects, and then the number of connected domains is counted and used to refer to the number of elevator objects. The elevator objects include both the elevator passengers and the goods carried by the elevator passengers, such as suitcases, carts, and trolleys.

[0060] Optionally, the identifying a plurality of elevator objects and their corresponding elevator feature information from the first area image data includes:

[0061] identifying a plurality of objects from the first region image data;

[0062] If the corresponding floor is equipped with an elevator, each of the objects is regarded as an elevator-riding object, and the elevator-riding feature information of each of the objects is extracted from the first area image data;

[0063] If the corresponding floor is equipped with multiple elevators, the body orientation information of each object is further extracted from the first area image data, and the elevator object associated with the target elevator door is determined based on the body orientation information, and the elevator feature information of each elevator object is extracted from the first area image data.

[0064] In this embodiment, each floor may be equipped with one or more elevators, and the camera will capture the real-life image of the entire elevator area. Obviously, not all objects contained in the real-life image need to enter the wire rope elevator from the target elevator door. In this regard, when it is determined that the corresponding floor is equipped with only one elevator, the identified objects should all be elevator objects, and then all objects extracted from the first area image data are identified as elevator objects, and then their corresponding elevator feature information is extracted. If it is determined that the corresponding floor is equipped with multiple elevators, the body orientation information of each object is extracted from the first area image data, and the object with the body facing the target elevator door is confirmed as an elevator object (other objects are elevator objects riding other elevators), and then their elevator feature information is obtained.

[0065] It should be noted that the number of elevators on the corresponding floors can be obtained through real-life image recognition captured by a camera, or can be directly retrieved from the building structure database, which will not be elaborated here.

[0066] Optionally, sending a second control instruction to a first weighing sensor according to each of the elevator riding characteristic information, and receiving a plurality of first weighing data fed back by the first weighing sensor, comprises:

[0067] The elevator riding characteristic information includes lower characteristic information of each of the elevator riding objects, and each of the elevator riding objects is divided into a first type, a second type and a third type according to the lower characteristic information; wherein the first type is a foot type, the second type is a wheel type, and the third type is a type other than the first type and the second type;

[0068] If each of the objects riding the elevator includes only the first type or only the first type and the third type, activating a plurality of third weighing sensors in the first weighing sensors at a first spacing distance;

[0069] If each of the objects riding the elevator includes only the second type or only the second type and the third type, activating a plurality of the third weighing sensors in the first weighing sensors at a second spacing distance;

[0070] If each of the objects riding the elevator includes at least the first type and the second type, all of the third weighing sensors in the first weighing sensors are activated;

[0071] Wherein, the first weighing sensor includes a plurality of strip-shaped third weighing sensors arranged in parallel, and the first spacing distance is smaller than the second spacing distance.

[0072] In this embodiment, refer to Figure 3 As shown, the first weighing sensor in the present invention is composed of a plurality of third weighing sensors arranged in parallel and in a strip shape. Adjacent third weighing sensors have a certain interval and can be activated separately.

[0073] The elevator feature information extracted by the aforementioned method includes the lower feature information of each elevator object. The lower feature information refers to the feature information extracted from the area below the middle position in the longitudinal direction of the elevator object. This feature information is used to characterize the walking method of the corresponding elevator object. In-depth analysis of the above lower feature information can divide the elevator objects into foot-type, wheel-type and other walking methods. For example, when the elevator object is a person, it belongs to the first type. When the elevator object is a cart (especially a self-movable smart cart or transport robot), a wheeled suitcase, etc., it belongs to the second type. When the elevator object is a cardboard box, it belongs to the third type. The third type is the type other than the first type and the second type. In fact, elevator objects such as carts are generally carried into the elevator by people or carts.

[0074] Therefore, when only the first type or only the first and third types of objects are included, it means that the objects are only people who walk on their feet and objects that cannot move by themselves, such as cartons that need to be carried by people. Since the step length during foot walking is large and the stepping point cannot be uniquely determined, a number of third weighing sensors with a smaller first spacing distance of the first weighing sensor are activated, so that it can be ensured that the footsteps of the person are accurately detected, and the person's feet will not fail to step on the third weighing sensor due to the large spacing. At the same time, the power consumption of the first weighing sensor can also be effectively reduced (because the third weighing sensor is not fully activated). When only the second type or only the second and third types of objects are included, it means that the objects are only objects that walk on wheels (the objects in this case are self-walking smart carts or transport robots, etc.) and objects that cannot move by themselves, such as cartons that need to be carried by objects that walk on wheels. Since objects that walk on wheels are always in contact with the ground, only a few third weighing sensors need to be activated, for example, only one third weighing sensor needs to be activated. When both the first type and the second type (with or without the third type) are included, all the third weighing sensors in the first weighing sensor are activated, which simplifies the activation principle of the third weighing sensors and prevents weighing omissions.

[0075] Optionally, judging whether the wire rope elevator has an overload risk according to the first weighing data and the second weighing data includes:

[0076] Calculate the remaining load data according to the second weighing data and the rated load data of the wire rope elevator, and update and calculate the remaining load data according to the first weighing data detected and transmitted in real time by the first weighing sensor;

[0077] When the remaining load data obtained by updating the calculation is lower than the overload threshold, it is determined that the wire rope elevator has an overload risk.

[0078] In this embodiment, after the wire rope elevator stops, the second weighing sensor in the elevator is activated to detect the real-time load data of the elevator, i.e., the second weighing data. The rated load data of the elevator is known in advance, and the difference between the two can be calculated to obtain the remaining load data. After the elevator door is opened, the passengers pass through the area where the first weighing sensor is located in turn. The first weighing sensor detects and obtains the corresponding first weighing data, and calculates and updates the remaining load data in real time. As the passengers gradually enter the elevator car, the remaining load data becomes smaller and smaller. When the remaining load data is lower than the overload threshold, it is determined that the wire rope elevator is at risk of overloading, and an overload warning signal is output in time accordingly. The overload warning signal is used to remind the passengers who have not yet entered the elevator car not to enter the elevator car again. Therefore, the present invention avoids the defect of the traditional method that the warning can only be given after the overload by weighing and warning in advance, and reduces the probability of the wire rope elevator being damaged due to overloading.

[0079] The overload threshold can be determined in the following way:

[0080] The number of passengers of the third type is counted, and the overload threshold is determined according to the number; wherein the overload threshold is positively correlated with the number.

[0081] Although the weight of the passengers entering the elevator can be predicted in advance and an early warning can be issued, these passengers may not pay attention to the early warning, so it is necessary to determine an appropriate overload threshold to ensure that even if the last passenger to enter does not comply with the overload warning, the elevator will not be damaged by overload. At the same time, the more the number of the third type of passengers, i.e., boxes, the greater the probability that they are carried into the elevator car by the first type and the second type of passengers, and the weight of the box itself cannot be detected by the camera, and it is obvious that the probability of the elevator being damaged by overload is also greater at this time. In this regard, the present invention sets the overload threshold to be positively correlated with the number of the third type of passengers, i.e., the number of the third type of passengers, i.e., the greater the overload threshold, i.e., when the remaining load data calculated by real-time update still has sufficient values, an early warning is issued to prevent the first type and the second type of passengers from carrying boxes exceeding the expected weight into the elevator; otherwise, the smaller the overload threshold is set.

[0085] The third processing module is used to send a second control instruction to the first weighing sensor according to each of the elevator riding characteristic information, and receive a plurality of first weighing data fed back by the first weighing sensor, and receive second weighing data fed back by the second weighing sensor; wherein the first weighing sensor is arranged in the passage area of ​​the target elevator door entering the wire rope elevator, and the second weighing sensor is arranged in the wire rope elevator;
