Detailed Description
In order to make the objects, technical solutions and advantages of the present invention more apparent, the present invention is described in further detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the invention and are not intended to limit the invention.
The elevator control method based on the pit ponding provided by the application can be applied to the application environment as shown in figure 1. The application environment includes a main controller 101 and a water accumulation detection device 102, which communicate via a network. According to the accumulated water detection device 102, the information of the accumulated water in the pit is obtained, and the main controller 101 judges whether the accumulated water can affect the running state of the elevator component or not according to the information of the accumulated water in the pit, so that the elevator is controlled, and the safe running of the elevator is ensured. The main controller 101 may be implemented by a server or a terminal, where the terminal may be, but is not limited to, various personal computers, notebook computers, smart phones, tablet computers, and portable wearable devices, and the server may be implemented by an independent server or a server cluster composed of multiple servers; the water accumulation detection device 102 may be, but is not limited to, a millimeter wave radar, a water immersion sensor, a water level sensor.
The embodiment of the invention provides an elevator control method and device based on pit ponding, computer equipment and a storage medium. The following are detailed below.
In one embodiment, as shown in fig. 2, a method of elevator control based on pit ponding is provided. Taking the application of the method to the master controller 101 in fig. 1 as an example for explanation, the method includes the following steps:
s201, acquiring pit accumulated water information and part height; the pit accumulated water information is obtained by monitoring a well pit by an accumulated water detection device; the component height includes the height of the elevator component relative to the hoistway pit.
The accumulated water detection device is a device capable of detecting whether accumulated water exists in a pit of the well and detecting the severity of the accumulated water (such as accumulated water depth, accumulated water area, accumulated water rising speed, accumulated water falling speed and the like), and can be realized through a millimeter wave radar, a water sensor, a water level sensor and the like. The accumulated water detection device can monitor the accumulated water condition of the pit in real time and send the accumulated water information of the pit to the master control in real time. When detecting that the pit has accumulated water, the accumulated water detection device can also send prompt information to the main controller.
An elevator component (also referred to as an elevator device) refers to a component related to the operation of an elevator, and may be a component inside a car, a component inside a hoistway outside the car, or a component outside the hoistway; the whole of the car, the counterweight, and the like may be used as an elevator component. Further, the embodiment of the invention mainly studies components susceptible to pit standing water. Specifically, the method may include: the pit buffer switch, the counterweight buffer switch, the speed governor tensioning wheel switch, the pit emergency stop switch, the pit illuminating lamp (power socket integration), the traction host machine and the like are arranged on the pit; it may also include components disposed on the bottom of the car, such as: a detection switch, a detection component, a diversion wheel, a guide wheel and the like. The elevator component receives the influence of ponding and can cause the maloperation of safety circuit etc. to cause the security threat for elevator, passenger and maintenance personnel.
Further, for elevator components fixedly installed on a pit or a hoistway, the height of the components can be determined according to the installation position, and the height of the components can also be detected by detectors such as millimeter wave radars and the like. For elevator components such as an elevator, a counterweight, a diversion sheave, a guide wheel and the like which move in real time, the height of the components can be detected by a detector. In addition, the height of the lowest position of the elevator component can be determined as the component height.
S202, determining the state influence information of the accumulated water on the elevator component according to the accumulated water information of the pit and the height of the component.
The hoistway pit surface may be used as a reference surface for determining height, for example: component height refers to the height of the component relative to the hoistway pit surface. And the height of the water surface of the accumulated water relative to the surface of the well pit can be determined according to the pit accumulated water information. Comparing the height of the water surface of the ponding with the height of the component, whether the height of the water surface exceeds the height of the component can be determined.
When the water level is higher than the height of the components, the elevator components are wetted by water, which may affect the normal operation of the elevator components and even threaten the personal safety. For example: firstly, a 110V safety circuit and a 220V maintenance circuit are laid in a pit; very easily electric leakage under the moist condition of pit ponding not only can cause the maintenance personal to electrocute, moreover because the elevator is holistic metallic structure, the electric current can directly pass to the car, causes the passenger to electrocute. Secondly, abnormal operation of the elevator can be caused; after water is accumulated in the pit, due to the fact that the humidity in the elevator shaft is too high, the safety contacts of the elevator door locks of all layers are corroded, the safety loop of the elevator pit is aged, the elevator cannot normally judge the safe operation condition, the door is opened and started, and the risk of shearing passengers exists; the basic safety mechanism can be disabled; can lead to the overspeed governor take-up pulley that is located the elevator pit to rust to die or skid behind the elevator pit ponding, and the compensation chain that is located elevator car bottom can take ponding to elevator track, room door, sedan-chair top and wire rope in high-speed motion on, in case the wire rope skids, the overspeed governor is exactly one last safety measure, because the overspeed governor take-up pulley can not normally work, the overspeed governor just also can't start, can directly cause and weigh down the ladder. In addition, the accumulated water in the pit can also influence the service life and the comfort level of the elevator; in the pit of long-term ponding, too high humidity can cause elevator main part metal structure serious corrosion, and each metal contact corrosion inefficacy, the elevator is very easily produced abnormal sound, blocks and pause, excessive friction scheduling problem, causes elevator part and whole ladder life-span to shorten.
Therefore, whether the accumulated water exceeds the height of the elevator component is determined according to the information of the accumulated water in the pit and the height of the component, and the information of the influence of the accumulated water on the state of the elevator component is obtained.
And S203, controlling the operation of the elevator according to the state influence information.
When judging that the accumulated water can affect the normal operation of elevator components, the elevator needs to be controlled to stop operation and the accumulated water is removed. On the other hand, if the fact that the water is not accumulated in the pit is determined, or the water accumulation condition does not influence the normal operation of the elevator slightly, the elevator can be controlled to continue the current operation state.
The elevator control method based on the accumulated water in the pit can automatically acquire the information of the accumulated water in the pit, effectively avoid the interference of human factors, prevent the occurrence of safety accidents caused by the fact that elevator components are immersed in water due to untimely manual detection, and ensure the safety of elevator operation.
In one embodiment, the water accumulation detection device comprises a millimeter wave radar; the method for acquiring the pit ponding information comprises the following steps: receiving first monitoring information of a hoistway pit sent by a millimeter wave radar; the first monitoring information comprises the height of water surface accumulated relative to a shaft pit and the lifting speed of the water surface; and obtaining the accumulated water information of the pit according to the height of the accumulated water and the lifting speed. Wherein, the ponding height also can be called the ponding depth.
The millimeter wave radar can detect whether or not liquid exists in a non-contact manner, and can detect the liquid level. As shown in fig. 3, millimeter wave radar 301 may be located on a side wall of hoistway 302 to detect the presence of water in hoistway pit 303. The millimeter wave radar 301 can transmit radar signals to the pit in real time, determine the water accumulation condition of the pit according to the reflected radar signals, obtain first monitoring information, and obtain pit water accumulation information according to the first monitoring information.
Fig. 4 is a schematic diagram of the determination of the water height by the millimeter wave radar (the angle of the millimeter wave radar with respect to the pit surface is not considered here). Wherein a represents the surface of the ponding water and b represents the surface of the pit. The level of the pit surface may be used as a reference surface and in the absence of standing water at the pit surface, the millimeter wave radar determines its distance H0 from the pit surface to determine standing water level height and component height. When the ponding is detected, the millimeter wave radar detects the distance H1 between the millimeter wave radar and the surface of the ponding water; the height of the ponding water surface relative to the reference surface can be determined by comparing the distance H1 with the distance H0, and the ponding height delta H is obtained.
Further, the rising and falling speeds of the water surface include an ascending speed and a descending speed. Particularly, the rising speed or the falling speed needs to be determined by combining the actual situation of accumulated water, and when the accumulated water is more and more serious, the corresponding speed is the rising speed. The real-time height of the accumulated water in a period of time is obtained, so that the height change of the accumulated water in the period of time can be analyzed, and the rising speed or the falling speed of the accumulated water can be obtained.
The water surface height of the water surface relative to the shaft pit included in the first monitoring information can be understood as the current water surface height. This embodiment passes through the current ponding height of millimeter wave radar detection and the lifting speed of ponding, just can determine the ponding change condition of present ponding condition and pit in a period of time in the future according to these information, and then can determine whether ponding can cause the influence to the normal operating of elevator part. In addition, the millimeter wave radar can actively detect the accumulated water condition of the pit, and compared with the passive detection condition, the accumulated water treatment timeliness can be ensured by the aid of the treatment mode, and the influence of the accumulated water in the pit on normal operation of elevator components is prevented.
Further, in one embodiment, the step of determining information about the effect of water accumulation on the condition of the elevator component based on pit water accumulation information and component height comprises: determining the predicted water accumulation height at a set time point according to the water accumulation height and the lifting speed; if the predicted accumulated water height is higher than the component height, determining the state influence information as influence; and if the predicted accumulated water height is lower than the component height, determining the state influence information as no influence.
Wherein, the forecast water accumulation height refers to the height of the water accumulation in a future period of time determined according to the known water accumulation height and the lifting speed. The set time point refers to a certain time point in the future, and can be determined according to actual conditions, and specifically, the set time point may be a time point corresponding to a time period of 1min, 5min, 1h and the like.
When the state influence information is judged to be influenced, the specific influence of the accumulated water on each part can be further determined. In addition, because the height of different elevator components is different, when the height of the accumulated water is predicted to be different, the affected elevator components are different. Based on the above, if A, B, C elevator components are provided, when the accumulated water height is predicted to exceed the component height of the elevator component A, the influence situation of the accumulated water on the running state of the elevator component A can be determined in a targeted manner, and the state influence information is determined as the influence; and the influence of the standing water on the operating state of the elevator components B and C is not determined for a while. Of course, the influence of the water accumulation on the individual elevator components can also be determined for each predicted water accumulation height.
On the other hand, the state influence information may be determined to be not influenced when the accumulated water height is predicted to be higher than the height of some elevator components (for example, components with good waterproof performance and components which do not influence the operation of the elevator even if the accumulated water influence) according to the importance degree and the influence degree of the elevator components.
In order to further prevent the accumulated water from causing safety influence on the running of the elevator, a prompt height can be arranged below the height of the part. If the predicted accumulated water height is lower than the prompt height, the safety of the elevator and elevator components is judged; if the predicted accumulated water height is higher than the prompt height and lower than the component height, the safety of the elevator and the elevator component is judged to be possibly threatened; if the predicted water accumulation height is higher than the component height, the elevator and the elevator component are judged to be influenced by the water accumulation.
According to the embodiment, the prediction of the height of the accumulated water is determined according to the height of the accumulated water and the lifting speed, and then the influence condition of the accumulated water on an elevator component in a future period is predicted, so that the elevator is controlled. The whole process can be automatically carried out, is not easily interfered by human factors, can obtain accurate ponding information, accurately controls the elevator, and ensures the safety of the elevator, passengers and maintenance personnel.
In one embodiment the step of controlling the operation of the elevator on the basis of the status impact information comprises: and controlling the elevator to normally run according to the state influence information.
In another embodiment the step of controlling the operation of the elevator on the basis of the status impact information comprises: and controlling the elevator to run to a safety floor and stopping elevator calling response according to the state influence information.
Wherein a safety floor means that as many elevator components as possible are not affected by water accumulation when the elevator is moving to the floor. The safety layer can be determined in real time according to actual conditions; for example, if the 1 st floor is soaked by accumulated water, the 2 nd floor, the 3 rd floor and the like can be used as safety floors; if the-1 st floor is soaked by the accumulated water, the 1 st floor, the 2 nd floor and the like can be used as safety floors.
Further, the step of controlling the operation of the elevator based on the state impact information comprises: if the state influence information is influence; acquiring running state information of an elevator; when the running state information is in a standby state, controlling the elevator to run to a safety floor, and stopping elevator calling response; when the running state information is in a passenger carrying state, controlling the elevator to run to the nearest floor, outputting prompt information, and stopping elevator calling response; wherein the prompt message is used for prompting passengers to evacuate the elevator.
Wherein, the running state information of the elevator can refer to the current state of the elevator, and can include: fault, standby, passenger, etc. More specific operational status information may also be included, such as: high speed uplink state, flat layer state, etc.
In addition, the step of controlling the operation of the elevator according to the state influence information includes: if the state influence information is no influence, acquiring the running state information of the elevator; and controlling the elevator to continuously run according to the current running state. For example, if the elevator is currently in the passenger-carrying uplink state, the passenger-carrying uplink state is continued and the elevator travels to the destination floor.
Further, the following information is now assumed: when the depth of the accumulated water is less than delta H1, each elevator component is above the water level, so that the safety influence on the operation of the elevator can not be caused in a short time, and the risk of misoperation of a safety loop can not exist; when the depth of accumulated water is higher than delta H2, the elevator components on the pit safety loop have the risk of water soaking, and the elevator safety loop may malfunction, so that the elevator is stopped suddenly during operation; a margin region is arranged between the delta H1 and the delta H2, and can be set according to actual conditions. Where Δ H2 may correspond to a part height and Δ H1 may correspond to a position below the part height.
If the main controller calculates that the height of the accumulated water is delta H (delta H < delta H1), the elevator can be controlled differently according to different change conditions of the accumulated water.
1. If the water level does not have rising trend, it is judged that the accumulated water cannot cause the fault of the elevator component, and the elevator can continue to normally carry passengers.
2. If the water level has a rising trend and the elevator is in a standby state; the main controller controls the elevator to rise to a safety floor, stops responding to an external call, and avoids the situation that the water level rises to the height of delta H2, so that a safety loop acts or the electric leakage risk exists; if the water level stops rising after the elevator runs to the safety floor, and the height of accumulated water is still less than delta H1, the elevator can be controlled to return to normal operation.
3. If the water level has a rising trend and the elevator is in a passenger carrying state; suppose the time for the water level to rise to Δ H2 is t1 and the running time for the elevator to reach the nearest floor in the current running direction is t 2; when the elevator runs to the nearest floor, the height of a device at the bottom of the elevator car from the surface of the pit is H; if t1> t2 and H > delta H2, the elevator is controlled to move to the nearest floor, the door is opened, people are released, passengers are reminded to evacuate the elevator quickly, and after all elevator people evacuate, the main controller can control the elevator to stop at the safety floor. If the elevator is in a descending state at present and the elevator reaches the nearest floor and has the risk of water soaking or false operation of a safety loop, the elevator is controlled to reversely ascend after being decelerated, people are placed on the nearest floor, and the risk of passengers being trapped is reduced.
According to the elevator control method based on the pit ponding, the depth variation of the elevator ponding is detected, the ponding variation trend is predicted, the operation of the elevator is controlled by combining the operation state of the elevator, the ponding variation trend and the influence of the ponding on elevator components, and the safety of the elevator components, passengers and maintenance personnel can be guaranteed to the greatest extent.
In one embodiment, the step of determining the information about the effect of standing water on the condition of the elevator component further comprises: if the state influence information is influenced, sending accumulated water indication information to a maintenance terminal; the accumulated water indicating information is used for indicating maintenance personnel to process the accumulated water.
The maintenance terminal can be an interphone, a smart phone, a personal computer and the like. The maintenance personnel may refer to persons related to elevator control, such as building managers and maintainers. The water accumulation indicating information can be output in the modes of voice, video, characters and the like. In addition, for the elevator in the passenger carrying state, when the elevator reaches a safety floor, the passengers can be prompted to leave the elevator area through voice broadcasting, character output, video broadcasting and the like. The method for controlling an elevator based on sump ponding of the present embodiment can be implemented by the structure shown in fig. 5. Specifically, the millimeter wave radar 501 sends pit ponding information to the main controller 502; when the main controller 502 determines that the accumulated water affects elevator components according to the pit accumulated water information, the main controller sends accumulated water indication information to the maintenance terminal 503 to prompt maintenance personnel to process the accumulated water; meanwhile, the main controller 502 controls the elevator to run to a safe floor and prompts passengers to evacuate the elevator through the voice broadcasting device 504. The voice broadcasting device can be a sound box, an elevator video player and the like.
The predicted water accumulation height refers to a height in a future period of time. At present, assuming that the predicted water accumulation height is the water accumulation height after t min, and the predicted water accumulation height is equal to the height of the part, the maintenance personnel can be instructed to clean the water accumulation within t min. If the accumulated water cannot be completely cleaned, the accumulated water is ensured not to be higher than the height of the part after t min.
According to the embodiment, when the situation that the accumulated water affects the normal operation of the elevator component is judged, the information that the accumulated water exists in the pit is notified to relevant personnel, and the relevant personnel are reminded to clear the accumulated water in the pit in time. The problem that other electrical devices in the well are subjected to moisture erosion to accelerate aging due to too high humidity of the well is avoided; meanwhile, the device of the water accumulation pit is prevented from being soaked by water and the risk of electric leakage is avoided, and the safety of the elevator, maintenance personnel and passengers is guaranteed.
In one embodiment, the main controller can record information such as the depth of accumulated water, the occurrence time of the accumulated water, the elevator fault type and the fault frequency during the accumulated water period and the like at each time, and the information is provided for the maintenance terminal platform, so that maintenance personnel can analyze the reason of the accumulated water and the influence of the accumulated water on the elevator conveniently. If the determined reason for the water accumulation is that the pit is waterproof, performing waterproof treatment on the pit; if the reason for water accumulation is that rainwater is poured from the bottom layer, corresponding rainproof measures and the like can be taken in advance; and the corresponding device can be checked in a targeted manner according to the fault condition.
In addition, after the main controller acquires the information that the elevator pit has ponding, the terminal platform can be sent ponding height, prediction ponding height and state influence information and the like so that relevant personnel can make the best emergency scheme to handle: if the accumulated water in the pit can not cause safety threat to the elevator in a short time, controlling the elevator to normally run, and simultaneously informing related personnel to clear the accumulated water in time; and if the accumulated water still exists in a period of time, continuously sending alarm information to urge related personnel to treat the accumulated water. If the accumulated water threatens the normal operation of the elevator, related personnel are informed to carry out emergency treatment, and the situation that the elevator cannot be taken and the use of a client is influenced is avoided.
In one embodiment, after the step of sending the water accumulation indication information to the maintenance terminal, the method further includes: receiving second monitoring information sent by the millimeter wave radar; if the fact that no accumulated water exists in the shaft pit is judged according to the second monitoring information, a safety inspection instruction is sent to the maintenance terminal; the safety inspection command is used for instructing maintenance personnel to perform safety inspection on elevator components in a shaft pit.
The second monitoring information and the first monitoring information can contain the same content, and the purpose of numbering and distinguishing the second monitoring information and the first monitoring information is to distinguish the functions of the second monitoring information and the first monitoring information, namely the first monitoring information refers to the monitoring information in the ponding detection process and is used for detecting whether the bottom pit has ponding or not; and the second monitoring information refers to the monitoring information after the accumulated water indicating information is sent to the maintenance terminal and is used for detecting whether the accumulated water in the pit is removed or not.
Specifically, after the millimeter wave radar detects that accumulated water is removed, the main controller sends information to relevant personnel to remind the personnel to perform safety inspection on the elevator pit device and dry the elevator pit device, so that the elevator part is prevented from being corroded by water; and related personnel can be prompted to perform trial run inspection on the elevator. After confirming that the elevator runs without abnormity, the elevator can be started to run normally.
The embodiment detects the ponding condition of pit to control elevator, dimension guarantor terminal etc. in view of the above, realize the unified cooperation in each aspect, guarantee elevator, passenger, dimension guarantor personnel's safety.
In order to better understand the above method, an application example of the elevator control method based on pit ponding of the present invention is explained in detail below.
1. And (3) monitoring the water accumulation condition of the well pit in real time by a millimeter wave radar installed on the side wall of the well to obtain pit water accumulation information, wherein the pit water accumulation information comprises the height of the water accumulation and the lifting speed of the water surface. And the millimeter wave radar sends the pit accumulated water information to the main controller.
