Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of electric control test, in particular to an elevator electric control comprehensive test device. BACKGROUND

[0002] The elevator electric control is a collective term for all key components in the elevator electrical control system, responsible for the command, drive, safety and interaction of the elevator, including the main control board, frequency converter, sensor, floor switch key board, main power switch and the like.

[0003] Among them, the test of the floor switch key board is particularly important. The key board is the core contact point for the interaction between passengers and the elevator system, and its failure may directly cause danger or panic. The test of the floor switch key board is essentially a pre-preliminary, comprehensive and quantifiable physical examination and stress test on the elevator nerve endings and human-machine interface. The purpose is not only to see if it can be used, but also to scientifically predict whether it can work reliably, safely and continuously under various extreme but possible conditions during the entire service life.

[0004] In summer, the shaft is like a "chimney", producing a chimney effect, gathering roof heat, causing high temperature inside the elevator, in winter, the shaft is connected with outdoor air, especially the top hall door gap will pour in cold wind, causing low temperature inside the elevator, in summer in the coastal rainy area, high temperature superimposed high humidity, so that the inside of the elevator produces hot and humid air, in the coastal area with large diurnal temperature difference in winter, the surface temperature of low temperature object drops below the dew point, causing water vapor to condense into water droplets, causing the inside of the basement elevator to produce cold and humid air.

[0005] And the existing floor switch key board test is only to test whether it can normally connect power on and transmit signals, and cannot test the floor switch key board in different environments in real time, which may cause the plastic to become brittle, the component parameters to drift, and the key to have no response or automatic false triggering in severe cold areas, causing elevator layer landing disorder and causing people to be trapped, in the "May rain season" in Jiangnan, the unverified key board may fail on a large scale due to internal condensation and circuit corrosion. In the northern winter, the basement key board may be directly short-circuited due to condensation.

[0006] Therefore, it is necessary to design an elevator electric control comprehensive test device that can simulate different environmental use. SUMMARY

[0007] The purpose of the present application is to provide an elevator electric control comprehensive test device to solve the problems raised in the background.

[0008] To solve the above-mentioned technical problems, the present invention provides the following technical solution: a comprehensive testing device for elevator control panels, including a test bench, a display fixedly connected to one side of the test bench, a simulated elevator component simulating elevator operation on the upper side of the test bench, a support frame fixedly connected to one side of the simulated elevator component, a camera for taking pictures of elevator operation fixedly connected to one side of the support frame, a high-temperature chamber for providing hot air fixedly connected to the upper side of the test bench, a condensation chamber for providing cold air on one side of the high-temperature chamber, a humidification chamber for providing water particles on one side of the high-temperature chamber, an environmental conversion mechanism for respectively fusing and switching hot air, cold air, and water particles on one side of the condensation chamber, and a simulation mechanism for testing the floor switch control panel with simulated low temperature, high temperature, hot and humid air, and cold and humid air environments on one side of the environmental conversion mechanism.

An air intake hole is also provided on the other side of the conversion cylinder. The output end of the high-temperature chamber is connected to the hot air hole pipe. The output end of the condensation chamber is connected to the cold air hole pipe. The output end of the humidification chamber is connected to the water mist hole pipe.

[0010] According to the above technical solution, the simulation mechanism includes a first air pump fixedly connected to the other side of the conversion cylinder, a simulation box on the other side of the first air pump, the input end of the first air pump communicating with the air intake and the output end communicating with the interior of the simulation box, an electrical wire hole on one side of the simulation box, a second air pump fixedly connected to one side of the simulation box and the input end of the second air pump communicating with the interior of the simulation box, a second motor fixedly connected to one side of the simulation box, a door on the upper side of the simulation box, a rotating column fixedly connected inside the door, one end of the rotating column being rotatably connected to the simulation box and the other end being fixedly connected to the output end of the second motor, and a pressing component on the upper side of the door.

[0011] According to the above technical solution, the interior of the box door is provided with a first sliding groove, the middle of the first sliding groove is provided with a first through groove, the upper side of the first sliding groove is slidably connected with a first slider, the upper side of the box door is fixedly connected with a second electric push rod, the output end of the second electric push rod is fixedly connected with a first positioning block, the first positioning block is fixedly connected with the first slider, and the middle of the interior of the first slider is provided with a second through groove.

[0012] According to the above technical solution, the pressing component includes a second positioning block fixedly connected inside the second through groove. A third electric push rod is fixedly connected to the upper side of the second positioning block. A second slider is fixedly connected to the output end of the third electric push rod, and the second slider is slidably connected to the second through groove. A fourth electric push rod is fixedly connected to the upper side of the second slider.

[0013] According to the above technical solution, the telescopic component includes several slide bars and several herringbone rubbers.

[0014] According to the above technical solution, a partition is fixedly connected inside the simulation box, and a slot is provided inside the partition.

[0016] According to the above technical solution, after the camera captures images of the surfaces of multiple conductors, it converts the images into electrical signals and sends them to the judgment module. The judgment module first compares them with the identification photos of different elevator operating states in the internal database to pre-identify the current elevator operating state. Based on the obtained elevator operating state photos, it distinguishes the contact resistance state of the floor switch button panel as normal and abnormal.

[0017] Compared with the prior art, the beneficial effects achieved by the present invention are:

[0018] 1. By using an environmental conversion mechanism to fuse and switch between hot air, cold air, and water particles, four different environments—low temperature, high temperature, hot and humid air, and cold and humid air—are brought into the simulation chamber. When used in conjunction with the floor switch control panel, this effectively prevents some floor switch control panels from being unable to adapt to different environments, thus avoiding the phenomenon of buttons not responding or automatically triggering falsely, causing the elevator to stop at random floors. This achieves a high level of testing accuracy.

[0019] 2. During the sliding of the first slider, the first through groove is always pressed by the first slider, preventing air from passing through. During the sliding of the second slider, each slider is driven to slide. When the two sliders approach each other, the herringbone rubber is compressed, and when the two sliders move away from each other, the herringbone rubber is stretched. Therefore, during the sliding of the second slider, air cannot pass through the second through groove, effectively preventing air leakage into the interior of the simulation box, affecting the accuracy of the environmental simulation of the simulation box, and thus affecting the accuracy of the floor switch button panel.

[0020] 3. In various simulated environments, the pressing component automatically presses each different button. At the moment of pressing, the camera automatically captures the elevator's operating status. This not only automatically tests the floor switch control panel under different environments, preventing delays or misreadings caused by human observation during testing, but also achieves automatic testing of the floor switch control panel with high accuracy. Furthermore, it prevents personnel from opening the box door, thus preventing the interior of the simulation box from being out of closed testing mode, affecting the internal simulated environment, and reducing test accuracy.

[0034] 10. Simulated elevator components. Detailed Implementation

[0035] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0036] Please see Figures 1-9The present invention provides a technical solution: an elevator control panel comprehensive testing device, including a test bench 1, a display 6 fixedly connected to one side of the test bench 1, a simulated elevator component 10 simulating elevator operation on the upper side of the test bench 1, a support frame 4 fixedly connected to the test bench 1 on one side of the simulated elevator component 10, a camera 3 for taking pictures of elevator operation fixedly connected to one side of the support frame 4, a high-temperature chamber 5 for providing hot air fixedly connected to the upper side of the test bench 1, a condensation chamber 7 for providing cold air on one side of the high-temperature chamber 5, a humidification chamber 2 for providing water particles on one side of the high-temperature chamber 5, an environment conversion mechanism 8 for respectively fusing and switching hot air, cold air and water particles on one side of the condensation chamber 7, and a simulation mechanism 9 for respectively testing the floor switch button panel with simulated low temperature, high temperature, hot and humid air and cold and humid air environments on one side of the environment conversion mechanism 8.

[0037] The specific explanation based on the above structure is as follows: The simulated elevator component 10 is a transparent simulated elevator model. Its core structure is exactly the same as that of a real elevator and can be regarded as a miniaturized real elevator. The internal motor output terminal simulates the traction machine in forward and reverse rotation, driving the car to accurately rise and fall and level on the track. In order to realize the linkage between the car door and each floor door, the model usually adopts a "car door drive mechanism" and a corresponding "floor door drive mechanism" for each floor. When the car is leveled, the control box 992 will trigger the linkage mechanism according to the precise timing sequence to realize the synchronous opening and closing of the doors. The simulated elevator component 10 is an existing structure and will not be described in detail here.

[0038] The interior of the high-temperature chamber 5 is equipped with a resistance heating wire or a metal heating tube. When powered on, heat is generated due to the resistance effect. There is a high-power centrifugal fan near the heating element, which blows hot air violently throughout the entire chamber and circulates it continuously to prevent heat from accumulating at the top, thereby ensuring the temperature uniformity within the space. The high-temperature chamber 5 is an existing structure and will not be described in detail here.

[0039] The working principle of the condenser box 7 is that the refrigerant inside evaporates in the evaporator, absorbing a large amount of heat from the air inside the box, causing the temperature of the air flowing through the evaporator to drop sharply, becoming a "cold source". The fan then blows the cold air throughout the interior of the condenser box 7. The condenser box 7 is an existing structure and will not be described in detail here.

[0040] The working principle of humidifier 2 is that the transducer generates high-frequency mechanical vibration, which violently tears the water into ultra-fine water mist with a diameter of 1-5 micrometers, thereby increasing the humidity in the air. Humidifier 2 is an existing structure and will not be described in detail here.

[0041] The environmental conversion mechanism 8 includes a support plate 85 fixedly connected to the upper side of the test bench 1. A conversion cylinder 82 is fixedly connected to the upper side of the support plate 85. Hot air holes 81 and cold air holes 84 are respectively provided on one side of the conversion cylinder 82. A water mist hole 83 is provided above one side of the conversion cylinder 82. A first motor 88 is fixedly connected to the other side of the conversion cylinder 82. The output end of the first motor 88 passes through the conversion cylinder 82 and is fixedly connected to a rotating shaft 86. A semi-circular baffle 87 is fixedly connected to the other end of the rotating shaft 86 and is slidably connected to the inner wall of the conversion cylinder 82. An air intake hole is also provided on the other side of the conversion cylinder 82. The output end of the high temperature chamber 5 is connected to the hot air hole 81 pipe. The output end of the condensation chamber 7 is connected to the cold air hole 84 pipe. The output end of the humidification chamber 2 is connected to the water mist hole 83 pipe.

[0042] The specific description of the above structure is as follows: water mist hole 83 is used for water particles generated by humidification box 2, hot air hole 81 is used for hot air generated by high temperature box 5, and cold air hole 84 is used for cold air generated by condensation box 7.

[0043] The rotation of the output end of the first motor 88 drives the rotating shaft 86 to rotate, thereby indirectly driving the semi-circular baffle 87 to rotate. Please refer to [link / reference]. Figure 4 The semi-circular baffle 87 is in its initial position. The hot air vent 81 and the water mist vent 83 can be vented, while the cold air vent 84 cannot be vented. When the output end of the first motor 88 rotates counterclockwise by 90 degrees, the cold air vent 84 and the water mist vent 83 cannot be vented, while the hot air vent 81 can be vented. When the output end of the first motor 88 rotates counterclockwise by 180 degrees, the hot air vent 81 and the water mist vent 83 cannot be vented, while the cold air vent 84 can be vented. When the output end of the first motor 88 rotates clockwise by 90 degrees, the cold air vent 84 and the water mist vent 83 can be vented, while the hot air vent 81 cannot be vented.

[0044] The simulation mechanism 9 includes a first air pump 92 fixedly connected to the other side of the converter cylinder 82. A simulation box 91 is provided on the other side of the first air pump 92. The input end of the first air pump 92 is connected to the air intake port and the output end is connected to the inside of the simulation box 91. A wire hole 911 is provided on one side of the simulation box 91. A second air pump 93 is fixedly connected to one side of the simulation box 91 and the input end of the second air pump 93 is connected to the inside of the simulation box 91. A second motor 94 is fixedly connected to one side of the simulation box 91. A door 95 is provided on the upper side of the simulation box 91. A rotating column 97 is fixedly connected inside the door 95. One end of the rotating column 97 is rotatably connected to the simulation box 91 and the other end is fixedly connected to the output end of the second motor 94. A pressing component 96 is provided on the upper side of the door 95.

[0045] The specific description of the above structure is as follows: the wire hole 911 is used to pass wires through, so that the control box 992 is connected to the simulated elevator component 10 by signal; the first air pump 92 is used to draw gas from the inside of the converter cylinder 82 into the inside of the simulated box 91; the second air pump 93 is used to draw air out of the inside of the simulated box 91; the rotation of the output end of the second motor 94 is used to drive the rotating column 97 to rotate, thereby driving the box door 95 to rotate along the rotating column 97, and thus opening or closing the box door 95.

[0046] The interior of the door 95 is provided with a first sliding groove 954, the middle of the first sliding groove 954 is provided with a first through groove, the upper side of the first sliding groove 954 is slidably connected with a first slider 953, the upper side of the door 95 is fixedly connected with a second electric push rod 951, the output end of the second electric push rod 951 is fixedly connected with a first positioning block 952, the first positioning block 952 is fixedly connected with the first slider 953, and the middle of the interior of the first slider 953 is provided with a second through groove.

[0047] The specific explanation of the above structure is as follows: the extension and retraction of the output end of the second electric push rod 951 is used to drive the first slider 953 to slide along the first slide groove 954, thereby driving the simulated pressing head 967 to move, and thus moving it between the left and right floor buttons 984.

[0048] The pressing assembly 96 includes a second positioning block 962 fixedly connected inside the second through groove. A third electric push rod 961 is fixedly connected to the upper side of the second positioning block 962. The output end of the third electric push rod 961 is fixedly connected to a second slider 966, and the second slider 966 is slidably connected to the second through groove. A fourth electric push rod 963 is fixedly connected to the upper side of the second slider 966. The output end of the fourth electric push rod 963 passes through the second slider 966 and is fixedly connected to a simulated pressing head 967. Both ends of the second slider 966 are provided with telescopic assemblies. One end of one telescopic assembly is connected to the second positioning block 962 and the other end is connected to the second slider 966. One end of the other telescopic assembly is connected to the second through groove and the other end is connected to the second slider 966.

[0049] The specific explanation of the above structure is as follows: the extension and retraction of the output end of the third electric push rod 961 is used to drive the second slider 966 to slide along the second through groove, thereby driving the simulated pressing head 967 to move, and thus moving it between the upper and lower floor buttons 984. The extension of the output end of the fourth electric push rod 963 is used to drive the simulated pressing head 967 to move up and down, so that it presses on the emergency button 981, the door opening button 982, the door closing button 983 and several floor buttons 984 respectively.

[0050] The telescopic assembly includes several slide bars 965 and several herringbone rubbers 964. Herringbone rubbers 964 are fixedly connected to both sides of each slide bar 965, and the two ends of the slide bar 965 are slidably connected to the inside of the second through groove.

[0051] The specific explanation based on the above structure is as follows: During the sliding of the first slider 953, the first through groove is always pressed by the first slider 953, preventing air from passing through. During the sliding of the second slider 966, each slider 965 is driven to slide. When the two sliders 965 approach each other, the herringbone rubber 964 is compressed, and when the two sliders 965 move away from each other, the herringbone rubber 964 is stretched. Therefore, during the sliding of the second slider 966, air cannot pass through the second through groove, effectively preventing air leakage into the interior of the simulation box 91, affecting the accuracy of the environmental simulation of the simulation box 91, and thus affecting the accuracy of the floor switch button panel.

[0052] The simulation box 91 is internally fixedly connected to a partition 912, and the partition 912 is internally provided with a slot 913. A control box 992 is located on the lower side of the partition 912. The control box 992 is provided on both sides with a first electric push rod 99, and the first electric push rod 99 is fixedly connected to the inner wall of the simulation box 91. The output end of the first electric push rod 99 is fixedly connected to a magnetic chuck 991. A pressing plate 98 is magnetically attached to the upper side of the magnetic chuck 991. An emergency button 981, a door opening button 982, a door closing button 983, and several floor buttons 984 are provided on the upper side of the pressing plate 98.

[0053] The specific description of the above structure is as follows: the slot 913 is used to place the floor switch button board. The size of the slot 913 fits the outer side of the floor switch button board. The magnetic chuck 991 is used to hold the floor switch button board. The extension and retraction of the output end of the first electric push rod 99 is used to drive the floor switch button board to move up and down, thereby embedding the floor switch button board into the slot 913 or removing it from the slot 913. The control box 992 is used to connect the signal to the floor switch button board that needs to be detected.

[0054] The display 6 has a judgment module and a database inside, and the database contains identification photos of different elevator operating states.

[0055] After camera 3 captures images of the surfaces of multiple conductors, it converts the images into electrical signals and sends them to the judgment module. The judgment module first compares the images with the identification photos of different elevator operating states in its internal database to pre-identify the current elevator operating state. Based on the captured photos of the elevator operating state, the module distinguishes the contact resistance state of the floor switch button panel as normal or abnormal.

[0056] When testing is required on one of the floor switch control panels, the output of the second motor 94 rotates counterclockwise to open the door 95. The output of the first electric push rod 99 extends, driving the magnetic chuck 991 to move upward. The operator connects the floor switch control panel to the control box 992 and uses the magnetic chuck 991 to hold the bottom of the floor switch control panel. The output of the first electric push rod 99 retracts, inserting the floor switch control panel into the slot 913. The output of the second motor 94 rotates clockwise to close the door 95.

[0057] High temperature, low temperature, hot and humid air, and cold and humid air environments can affect the contact resistance of floor switch control panels to varying degrees. When the floor switch control panel is defective, high temperature, low temperature, hot and humid air, and cold and humid air will seriously affect the contact resistance of the floor switch control panel, thereby causing it to fail or become insensitive.

[0058] First, a contact resistance test is performed on the floor switch control panel in a cold air environment. When the output terminal of the first motor 88 rotates counterclockwise by 180 degrees, the hot air vent 81 and the water mist vent 83 are blocked, while the cold air vent 84 is open. The condenser box 7 is opened, and the first air pump 92 is started. The first air pump 92 draws cold air from inside the condenser box 7. The cold air passes through the inside of the converter cylinder 82 and enters the inside of the simulation box 91. At this time, the simulation box 91 is filled with cold air. The output terminals of the second electric push rod 951, the third electric push rod 961, and the fourth electric push rod 963 extend and retract, driving the simulated pressing head 967 to sequentially press the emergency button 981 and the door open button. When buttons 982, 983, and 984 are pressed, camera 3 captures an image of the elevator each time it is pressed. When button 982 is pressed, the camera captures whether the elevator door opens normally; when button 983 is pressed, the camera captures whether the elevator door closes normally; when button 984 is pressed, the camera captures whether the elevator moves up or down. If the elevator fails to respond promptly when one of the buttons is pressed, the judgment module determines that the contact resistance of the floor switch button board is abnormal. If the elevator responds promptly after all buttons are pressed, the judgment module determines that the contact resistance of the floor switch button board is normal.

[0059] Next, a contact resistance test is performed on the floor switch button panel in a cold and humid environment. The output of the first motor 88 rotates first, driving the semi-circular baffle 87 to return to its original position. Then, the output of the first motor 88 rotates 90 degrees clockwise. At this time, the cold air vent 84 and the water mist vent 83 can be vented, while the hot air vent 81 cannot be vented. The condenser box 7 is opened, the humidifier box 2 is started, and the first air pump 92 is started. The first air pump 92 draws cold air and water particles from the inside of the condenser box 7. The cold air and water particles pass through the inside of the conversion cylinder 82 and enter the inside of the simulation box 91. The cold air and water particles react and evolve into cold and humid air. At this time, the simulation box 91 is filled with cold and humid air. The subsequent process for judging whether the contact resistance of the floor switch button panel is normal or abnormal has been explained above and will not be repeated here.

[0060] Next, a contact resistance test is performed on the floor switch button panel in a hot air environment. The output end of the first motor 88 rotates first, driving the semi-circular baffle 87 to return to its original position. When the output end of the first motor 88 rotates counterclockwise by 90 degrees, the cold air vent 84 and the water mist vent 83 are not open, while the hot air vent 81 is open. The high-temperature chamber 5 is opened, and the first air pump 92 is started. The first air pump 92 draws hot air from inside the high-temperature chamber 5. The hot air passes through the inside of the converter cylinder 82 and enters the inside of the simulation chamber 91. At this time, the inside of the simulation chamber 91 is filled with hot air. The subsequent process for judging whether the contact resistance of the floor switch button panel is normal or abnormal has been explained above and will not be repeated here.

[0061] Finally, a contact resistance test was performed on the floor switch button panel in a hot and humid environment. The output of the first motor 88 rotated, causing the semi-circular baffle 87 to return to its original position. At this time, the semi-circular baffle 87 was in its initial placement state. The hot air hole 81 and the water mist hole 83 could be ventilated, while the cold air hole 84 could not be ventilated. The high-temperature chamber 5 was opened, the humidification chamber 2 was started, and the first air pump 92 was started. The first air pump 92 extracted the hot air and water particles inside the high-temperature chamber 5. The hot air and water particles passed through the inside of the conversion cylinder 82 and entered the inside of the simulation chamber 91. The hot air and water particles reacted and evolved into hot and humid air. At this time, the simulation chamber 91 was filled with hot and humid air. The subsequent process for judging whether the contact resistance of the floor switch button panel is normal or abnormal has been explained above and will not be repeated here.
