The outdoor escalator is arranged outdoors and can be wetted by rain and snow when raining or snowing. The outdoor escalator comprises a driving assembly, a lubricating assembly, steps, a handrail belt, a detection module, a weather acquisition assembly and a control system. The steps are mobile platforms for passengers to stand. The handrail belt is a belt-shaped part for passengers to hold. The driving assembly is connected to the steps and the handrail belt and is used for driving the steps and the handrail belt to synchronously move.
The drive assembly includes a motor and a transmission mechanism. The motor is connected to the transmission mechanism, and the transmission mechanism is connected to the steps. The torque output by the motor is output to the steps after being reduced in speed and increased in torque through the transmission mechanism, so that the steps are driven to move. In this embodiment, the transmission mechanism includes a plurality of sprockets and a drive chain. The sprocket wheel is meshed with the transmission chain. A plurality of sprockets tightens the drive chain. The transmission chain is connected with the steps and can pull the steps to do rotary motion.
The lubrication assembly is used to deliver lubricant to the transmission to reduce friction and wear of the transmission. The lubrication assembly includes a pump, a container, a first delivery tube, a second delivery tube, and a brush. The container is for holding a lubricant. The lubricant may be in a liquid state. The pump may be an oil pump. The pump includes an inlet and an outlet, and the pump is capable of drawing fluid from the inlet and outputting the fluid from the outlet. The two ends of the first conveying pipe are respectively connected with the container and the inlet of the pump, and the inlet of the pump is communicated with the container through the first conveying pipe. The two ends of the second conveying pipe are respectively connected with the outlet of the pump and the brush, and the outlet of the pump is communicated with the brush through the second conveying pipe. The bristles of the brush are in flexible contact with the transmission mechanism. In this embodiment, the bristles on the brush are in flexible contact with the drive chain. In this way, the pump can pump lubricant in the container to the brush, and the lubricant on the brush is coated on the transmission chain along the bristles of the brush. The links on the drive chain can be coated with lubricant sequentially through the bristles of the brush.
The detection module is used for detecting the load of the motor. The frictional resistance of the transmission mechanism increases significantly when the transmission mechanism lacks lubricating oil, which results in an increase in the load of the motor. The detection module determines whether the transmission mechanism lacks lubricating oil by detecting the load of the motor.
The weather acquisition component is used for acquiring weather information. The weather acquisition assembly includes a communication module and a rain and snow sensor. The communication module may communicate with one or more information networks such as a Local Area Network (LAN), a Wide Area Network (WAN) and/or a public network such as the Internet. The communication module can acquire weather information of the outdoor escalator from an information network. The weather information may include weather type, precipitation amount, and precipitation time. The rain and snow sensor is used for measuring whether precipitation exists.
The control system is a logic control unit of the outdoor escalator. The control system can be a cloud computing server or a singlechip. The control system is electrically connected to the motor of the drive assembly, the pump of the lubrication assembly, the communication module of the weather acquisition assembly and the rain and snow sensor. The control system may be a pump connected to the motor of the drive assembly and the lubrication assembly through the internet of things.
The application also provides a control method of the outdoor escalator, and the control method is implemented based on the outdoor escalator. The control method comprises the following steps:
step S1: the control system acquires current weather information of the outdoor escalator location, and the step S2 is entered;
the control system can inquire weather information of the outdoor escalator on the information network through the communication module. For example, the address of the outdoor escalator is sent to the weather network, the local weather information can be queried on the weather network, and then the current weather information can be obtained from the local weather information according to the current time.
Weather information includes weather types including sunny, cloudy, light, medium, heavy, extremely heavy, light, medium, heavy, and snowy; wherein, the rain is light, medium, heavy, extremely heavy, light, medium, heavy and heavy, and the snow is precipitation weather.
Step S2: judging whether the outdoor escalator is in a rainy or snowy weather or not according to the current weather information, if so, entering a step S3, otherwise, entering a step S1;
when the weather type of the current weather information is any one of light rain, medium rain, heavy rain, extra heavy rain, small snow, medium snow, large snow and riot snow, the outdoor escalator is considered to be in the current rainy and snowy weather.
Step S3: acquiring the current load of the motor, and entering step S4;
the control system detects the load of the motor through the detection module. The load of the motor may be characterized by the output torque of the motor. The output torque of the motor can be directly used for representing the load of the motor, and can be converted into the load of the motor. The detection module measures the output torque of the motor, and the control system determines the load size of the motor according to the output torque of the motor. The output torque of the motor is positively correlated with the load of the motor.
The load of the motor may also be characterized by the current of the motor. The current of the motor may be directly used to represent the load of the motor, or the current of the motor may be converted into the load of the motor. The detection module measures the current of the motor, and the control system determines the load of the motor according to the current of the motor. The current of the motor is positively correlated to the load of the motor.
Step S4: judging whether the current load of the motor is greater than a preset threshold value, if so, entering a step S5, otherwise, entering a step S3;
the predetermined threshold is a predetermined value. The preset threshold value is slightly larger than the load of the motor when the transmission mechanism is in a normal lubrication state. The value range of the preset threshold value can be 1.05-1.25 times of motor load when the transmission mechanism is in a normal lubrication state. The normal lubrication state can be the lubrication state of the transmission mechanism which is just added with the primary lubricating oil.
The control system compares the current load of the motor with a preset threshold value, and if the current load of the motor is larger than the preset threshold value, the control system indicates that the lubrication of the transmission mechanism is insufficient and the lubricant needs to be supplemented; and if the current load of the motor is not greater than the preset threshold value, the transmission mechanism is sufficiently lubricated, and the lubricant does not need to be supplemented.
Step S5: the drive lubrication assembly adds lubricant to the transmission.
When the lubrication of the transmission mechanism is insufficient, the control system drives the lubrication assembly to output lubricant to the transmission mechanism so that the lubrication of the transmission mechanism is normal. Specifically, the control system drives the pump of the lubrication assembly to operate, the pump pumps lubricant in the container to the brush, and the brush coats the lubricant on the drive chain of the drive mechanism as the drive chain passes through the brush. The duration of the control system driving the pump may be one revolution of the drive chain, so that the brush may just coat the drive chain with lubricant and the coating may be uniform.
Therefore, in rainy and snowy weather, the outdoor escalator can be added with the lubricant as required, so that the outdoor escalator is ensured to keep a good lubrication state all the time, poor lubrication and too fast abrasion caused by too low lubricant adding frequency can be avoided, and the lubricant waste caused by too high lubricant adding frequency can be avoided.
In one illustrative embodiment, in step S3, the current load of the motor is obtained when the outdoor escalator is in an empty state.
The no-load state of the outdoor escalator is a state that the steps of the outdoor escalator are not loaded with people or things. In step S4, the preset threshold is 1.05-1.25 times of the load of the motor when the outdoor escalator is in an idle state and the transmission mechanism is in a normal lubrication state.
Therefore, the influence of the load of the motor caused by the carrying of people and objects on the outdoor escalator can be eliminated, and whether the lubrication of the transmission mechanism is insufficient or not is judged more accurately in the subsequent steps through the load of the motor.
In one illustrative embodiment, an outdoor escalator includes a normal operating condition and an energy saving operating condition. The outdoor escalator runs in a normal running state when carrying people and/or objects. The outdoor escalator runs in an energy-saving running state when people and objects are not carried. The rotating speed of the motor is lower in the energy-saving running state than in the normal running state, so that the energy-saving purpose is achieved.
In step S3, the idle state is an energy-saving operation state of the outdoor escalator. After the outdoor escalator enters an energy-saving running state, the control system detects the load of the motor through the detection module.
When the outdoor escalator enters an idle energy-saving running state, the load of the motor is triggered and measured, and the control is simpler.
In an exemplary embodiment, the control method further includes steps S6 to S10 after step S5.
Step S6: the lubricant filling times are increased once, and the step S7 is carried out;
the number of lubricant injections is the number of lubricant additions to the transmission. The control system controls the lubrication assembly to count the number of lubricant injections each time lubricant is added to the transmission.
Step S7: judging whether the filling times of the lubricant are larger than or equal to preset times, if so, entering a step S8, otherwise, entering a step S3;
the preset times are preset values, and the value range is more than or equal to 2 times.
In this way, the control system may control the lubrication assembly to add lubricant to the transmission multiple times until the number of lubricant injections reaches a preset number or it is detected that the load of the current load of the motor is below a preset threshold. The time interval between two adjacent additions of lubricant to the transmission is greater than the time required to add lubricant to the transmission in a single pass. For example, in step S5, the time required for adding the lubricant to the transmission is 180S, and the process proceeds to step S3 at a time interval of 300S after the lubricant is added once to the transmission.
Step S8: acquiring the current load of the motor, and entering step S9;
step S9: judging whether the current load of the motor is greater than a preset threshold value, if so, entering a step S10;
after the number of lubricant filling times reaches the preset number of times, detecting again whether the load of the current load of the motor is below a preset threshold value. If the current load of the motor is below a preset threshold value, the lubrication of the outdoor escalator is normal, and the lubricant does not need to be added again. If the current load of the motor is greater than the preset threshold value, the lubrication of the outdoor escalator is still abnormal, and the problem that the lubricant can not be added is solved.
Step S10: an alarm message is issued.
The control system can send alarm information to maintenance personnel of the outdoor escalator through the communication module, and can send the alarm information to a terminal of the maintenance personnel. The terminal can be a desktop computer, a mobile terminal such as a mobile phone and a tablet personal computer. After receiving the alarm information, maintenance personnel can timely go to the outdoor escalator site to overhaul the outdoor escalator. For example, to check whether a pump in the lubrication assembly is damaged or a blockage in a flow passage in the lubrication assembly that carries lubricant occurs.
In an exemplary embodiment, in step S5, the lubricant loading is controlled, the first time the lubricant is added the lubricant loading being equal to the preset lubricant amount. Starting with the second lubricant addition, the lubricant filling amount is adjusted according to the magnitude of the current load of the electric motor, and each lubricant filling amount is positively correlated with the current load.
From the second time of adding the lubricant, the larger the current load is, the larger the lubricant charge amount is, and the smaller the current load is, the smaller the lubricant charge amount is.
For example, after the first addition of the preset lubricant amount, the load value of the motor is reduced from 1.2 times the load value of the motor at the time of normal lubrication to 1.05 times the load value of the motor at the time of normal lubrication, and the lubricant amount is preset by controlling the rotation speed of the pump so that the amount of the lubricant to be added for the second time is one-half the preset lubricant amount at the time of the second addition of the lubricant.
The lubricant filling amount is adjusted according to the current load of the motor, so that the lubricant can be saved.
In an exemplary embodiment, step S2 includes S21-S25.
Step S21: judging whether the precipitation amount of the outdoor escalator is larger than or equal to the preset precipitation amount according to the current weather information, if so, entering a step S22, otherwise, entering a step S23;
the preset precipitation amount is a preset value and can be set according to the waterproof grade of the outdoor escalator. The higher the waterproof level of the outdoor escalator, the higher the preset precipitation amount can be set.
The precipitation amount of the outdoor escalator can be obtained according to the weather type in the current weather information. For example, the daily precipitation of light rain is 0.1-9.9 mm, the daily precipitation of medium rain is 10.0-24.9 mm, the daily precipitation of heavy rain is 25.0-49.9 mm, the daily precipitation of heavy rain is 50.0-99.9 mm, the daily precipitation of heavy storm is 100-250 mm, and the daily precipitation of extra heavy storm is more than 250 mm. The daily precipitation of the small snow is 0.1-2.5 mm, the daily precipitation of the medium snow is 0.1-5.0 mm, and the daily precipitation of the large snow is more than 5.0 mm.
The preset precipitation amount may take a value of 50.0 mm for daily precipitation. And when the precipitation amount of the outdoor escalator is above the heavy rain, namely the current weather type is heavy rain, heavy rain or extra heavy rain, the step S22 is carried out.
Step S22: the power supply of the outdoor escalator is cut off, and the process advances to step S21.
The control system can cut off the power supply of the outdoor escalator when the precipitation amount of the outdoor escalator is larger than or equal to the preset precipitation amount, and short circuit or electric leakage of the outdoor escalator due to invasion of rainwater is prevented.
Step S23: judging whether the power supply of the outdoor escalator is cut off, if so, entering a step S24, otherwise, entering a step S25;
step S24: switching on the power supply of the outdoor escalator, and entering step S25;
and the control system is used for switching on the power supply of the outdoor escalator again when the precipitation amount of the outdoor escalator is smaller than the preset precipitation amount.
Step S25: and judging whether the outdoor escalator is in a rainy or snowy weather or not according to the current weather information, if so, entering a step S3, otherwise, entering a step S1.
Therefore, when the current precipitation amount is smaller than the preset precipitation amount, the outdoor escalator only works, so that the outdoor escalator can be prevented from being damaged due to short circuit, and the outdoor escalator can be prevented from being leaked to hurt people.
In an exemplary embodiment, step S25 includes steps S251-S252.
Step S251: judging whether the outdoor escalator is in a rainy or snowy weather or not according to the current weather information, if so, entering a step S252;
step S252: and (3) measuring whether the outdoor escalator is subjected to precipitation or not through a rain and snow sensor, if so, entering a step (S3), otherwise, entering a step (S1).
After the control system judges whether the outdoor escalator is in rainy or snowy weather or not through the current weather information, the control system further verifies the current weather information by measuring whether the outdoor escalator is in precipitation or not through the rainy or snowy sensor.
If the rain and snow sensor detects rainfall, such as rainfall or snowfall, at the outdoor escalator location, the current weather information is accurate, and the outdoor escalator location is in rainy and snowy weather. If the rain and snow sensor detects that the outdoor escalator is not precipitation, the current weather information is inaccurate, and the outdoor escalator is likely not to rainfall or fall snow.
By further verifying the current weather information, the accuracy of judging whether the outdoor escalator is in the rainy or snowy weather can be improved.
The foregoing description is only of the preferred embodiments of the present invention and is not intended to limit the scope of the invention, and all equivalent structural changes made by the specification and drawings of the present invention or direct/indirect application in other related technical fields are included in the scope of the present invention.
