Description

Technical Field

[0002] With the rapid development of equipment control technology, unmanned control technology has been widely applied to various types of lifts. When the control type of the lift is manual control, the operator needs to be located on the working platform of the lift and use the electric control device to control the lifting of the working platform. When the control type of the lift is unmanned control, the operator can be located at a position outside the working platform such as on the ground, and through a human-machine interaction device such as a handle, remotely send a control instruction to the electric control device to control the lifting of the working platform.

[0003] However, even though unmanned control technology has been widely applied in lift control, due to factors such as the requirements of special operation tasks and the limitations of complex environments, the unmanned lift still needs to be converted into a manually controlled lift according to the actual operation scenario requirements. Since the integration degree of the lift is getting higher and higher, the components required for unmanned control are difficult to disassemble, resulting in low transformation efficiency of the lift and making the lift unable to meet the requirements of different control scenarios. In addition, after disassembling the components required for unmanned control, it is also possible that the lift cannot operate reliably, further making the lift unable to meet the requirements of different control scenarios.

[0060] Please refer to Figure 1 , Figure 1 which schematically shows a first structural diagram of the electric control device of the unmanned lift with main electric control plus auxiliary electric control according to an embodiment of the present application.

[0061] Figure 1 The electric control device 100 in [[ ]] includes a main electric control device 110 and a detachable auxiliary electric control device 120. The main electric control device 110 includes a main frequency converter 111 and a main motor 112. The auxiliary electric control device 120 includes a door frequency converter 121, a door motor 122, a communication sub-device 123 and a human-machine interaction sub-device 124;

[0062] The main frequency converter 111 is connected to the main motor 112. The communication sub-device 123 is respectively connected to the door frequency converter 121 and the human-machine interaction sub-device 124. The main frequency converter 111 is connected to the door frequency converter 121 through a detachable communication line;

[0063] The communication sub-device 123 is configured to obtain the operation information of the unmanned lift 10 and send the operation information to the door frequency converter 121;

[0064] The door frequency converter 121 is configured to generate a first current control parameter according to the operation information and send the first current control parameter to the door motor 122;

[0065] The door motor 122 is configured to drive the cage door 300 of the unmanned lift 10 according to the first current control parameter;

[0066] The main frequency converter 111 is configured to generate a second current control parameter according to the operation information and send the second current control parameter to the main motor 112, wherein the operation information is sent to the main frequency converter 111 through the door frequency converter 121;

[0067] The main motor 112 is configured to drive the cage 200 of the unmanned lift 10 according to the second current control parameter;

[0068] The human-machine interaction sub-device 124 is configured to display the operation information.

[0069] Unmanned control technology is widely used in the control of elevators. Due to the requirements of special operation tasks and the influence of complex environmental restrictions and other factors, the unmanned elevator still needs to be transformed into a manually controlled elevator according to the actual operation scenario requirements. In this embodiment, the electric control device 100 includes a main electric control device 110 and a detachable sub-electric control device 120. The main electric control device 110 includes a main frequency converter 111 and a main motor 112. The sub-electric control device 120 includes a door frequency converter 121, a door motor 122, a communication sub-device 123, and a human-machine interaction sub-device 124.

[0070] The communication sub-device 123 is respectively connected to the door frequency converter 121 and the human-machine interaction sub-device 124. In the unmanned control scenario of the elevator, the communication sub-device 123 obtains the operation information of the unmanned elevator 10 and sends the operation information to the door frequency converter 121. It should be understood that the type of operation information is set according to actual needs, which can be the travel information and power supply information of the elevator, etc., and will not be limited here.

[0071] A frequency converter is a power control device that controls an AC motor by changing the frequency of the working power supply. With the change of the functional requirements of the frequency converter, devices such as PLC (Programmable Logic Controller) and switching power supplies are usually integrated into the frequency converter. When both the main frequency converter 111 and the door frequency converter 121 integrate PLCs, after the door frequency converter 121 determines that the cage door 300 of the unmanned elevator 10 can be safely opened or closed according to the operation information such as the cage door 300 running to the limit position, the first current control parameter is generated. The door frequency converter 121 sends the first current control parameter to the door motor 122, and the door motor 122 drives the cage door 300 of the unmanned elevator 10 to open or close according to the first current control parameter.

[0072] When both the main frequency converter 111 and the door frequency converter 121 integrate PLCs, the operation information obtained by the communication sub-device 123 is sent to the main frequency converter 111 through the door frequency converter 121. The main frequency converter 111 determines that the cage 200 of the unmanned elevator 10 can be safely run upward or downward according to the operation information such as the travel limit information and power supply information, and generates the second current control parameter. The main frequency converter 111 sends the second current control parameter to the main motor 112, and the main motor 112 drives the cage 200 of the unmanned elevator 10 to run upward or downward according to the second current control parameter. In the unmanned control scenario of the elevator, the human-machine interaction sub-device 124 is used to communicate with the communication sub-device 123 and display the operation information sent by the communication sub-device 123.

[0073] In the manual control scenario of the elevator, the user usually manually controls the opening or closing of the cage door 300. Only the main frequency converter 111 drives the cage 200 to move upward or downward through the main motor 112. In the unmanned control scenario of the elevator, the secondary electric control device 120 controls the opening or closing of the cage door 300 according to the collected operation information. Devices such as the door frequency converter 121, door motor 122, communication sub-device 123, and human-machine interaction sub-device 124 required for the unmanned operation of the elevator are all integrated in the detachable secondary electric control device 120, and the main electric control device 110 and the secondary electric control device 120 are connected by a detachable communication line. While the electric control device 100 is highly integrated, the secondary electric control device 120 can be directly detached according to the actual control scenario requirements. On the basis of not requiring re-wiring or adding new devices, the unmanned elevator 10 can be quickly transformed into a manually controlled elevator. The transformed elevator can operate reliably and meet the requirements of different control scenarios.

[0074] Please also refer to Figure 2 , Figure 2 which schematically shows a second structural diagram of the electric control device of the unmanned elevator with the main electric control plus the secondary electric control according to an embodiment of the present application.

[0075] In an embodiment of the present application, the main electric control device 110 further includes a main controller 113, and the secondary electric control device 120 further includes a door controller 125;

[0076] The main controller 113 is connected to the door controller 125 through a detachable communication line. The main controller 113 is connected to the main motor 112 through the main frequency converter 111. The door controller 125 is connected to the door motor 122 through the door frequency converter 121;

[0077] Both the communication sub-device 123 and the human-machine interaction sub-device 124 are connected to the door frequency converter 121 through the door controller 125;

[0078] The communication sub-device 123 is configured to obtain the operation information of the unmanned elevator 10 and send the operation information to the door controller 125;

[0079] The door controller 125 is configured to generate a first control instruction according to the operation information and send the first control instruction to the door frequency converter 121;

[0080] The door frequency converter 121 is further configured to generate a first current control parameter according to the first control instruction and send the first current control parameter to the door motor 122;

[0081] The main controller 113 is configured to generate a second control instruction according to the operation information and send the second control instruction to the main frequency converter 111, where the operation information is sent to the main controller 113 through the door controller 125;

[0082] The main frequency converter 111 is also used to generate a second current control parameter according to the second control instruction and send the second current control parameter to the main motor 112.

[0083] Due to different models of actual frequency converters, the controller may or may not be integrated inside the frequency converter. When neither the main frequency converter 111 nor the door frequency converter 121 is integrated with a PLC, both the main frequency converter 111 and the door frequency converter 121 are used to adjust the working power supply frequency. At this time, the main electric control device 110 further includes a main controller 113, and the secondary electric control device 120 further includes a door controller 125.

[0084] It should be understood that the types of the main controller 113 and the door controller 125 are set according to actual requirements and can be a PLC, an MCU (Micro Control Unit), etc., which are not limited herein. It should also be understood that the main controller 113 and the door controller 125 can be integrated into one controller, or the main controller 113 and the door controller 125 can be two independent controllers, which are not limited herein. For ease of understanding, in the embodiments of the present application, the main controller 113 and the door controller 125 are two independent PLCs.

[0085] When the door frequency converter 121 is not integrated with a PLC, both the communication sub-device 123 and the human-machine interaction sub-device 124 are connected to the door frequency converter 121 through the door controller 125. The communication sub-device 123 sends the obtained operation information of the drone lift to the door controller 125. The door controller 125 generates a first control instruction according to the collected operation information and sends the first control instruction to the door frequency converter 121. The door frequency converter 121 generates a first current control parameter according to the received first control instruction and sends the first current control parameter to the door motor 122 to drive the cage door 300 to open or close through the door motor 122.

[0086] When the main frequency converter 111 is not integrated with a PLC, the main controller 113 is used to generate a second control instruction and send the second control instruction to the main frequency converter 111. The main frequency converter 111 generates a second current control parameter according to the received second control instruction and sends the second current control parameter to the main motor 112 to drive the cage 200 to move upward or downward through the door motor 122.

[0087] Specifically, in the unmanned control scenario of the elevator, the operation information obtained by the communication sub-device 123 is sent to the main controller 113 through the door controller 125. The main controller 113 generates a second control instruction according to the operation information. In addition, the operation information obtained by the communication sub-device 123 is sent to the human-machine interaction device through the door controller 125 to display the operation information through the human-machine interaction device. It should be understood that the door controller 125 can send at least one of the height, speed, and limit information of the elevator in the operation information to the human-machine interaction device according to the actual information display requirement, which will not be elaborated here.

[0088] In the manual control scenario of the elevator, after directly disassembling the communication line between the main controller 113 and the door controller 125, the auxiliary electric control device 120 is disassembled quickly to transform the unmanned elevator 10 into a manually controlled elevator. The main controller 113 generates a second control instruction according to the operations of the user on devices such as control buttons and control handles.

[0089] In the embodiment of the present application, the main electric control device 110 further includes an encoder 114;

[0090] The main motor 112 and the main controller 113 are respectively connected to the encoder 114;

[0091] The encoder 114 is used to convert the collected operation information of the unmanned elevator 10 into an electrical signal and send the electrical signal to the main controller 113;

[0092] The main controller 113 is further used to generate the operation information to be displayed according to the electrical signal and send the operation information to be displayed to the door controller 125;

[0093] The human-machine interaction sub-device 124 is further used to display the operation information to be displayed, where the operation information to be displayed is sent to the human-machine interaction sub-device 124 through the door controller 125.

[0094] Generally, the unmanned elevator 10 further includes detection devices such as speed sensors. The detection devices are used to collect operation information such as the height and speed of the unmanned elevator 10. For ease of understanding, in the embodiments of the present application, the encoder 114 is connected to the main controller 113 through the main frequency converter 111. The encoder 114 converts the collected height and speed operation information into electrical signals and sends the electrical signals to the main controller 113. The main controller 113 generates the operation information to be displayed according to the electrical signals and sends the operation information to be displayed to the door controller 125. For ease of understanding, in the embodiments of the present application, the human-machine interaction sub-device 124 needs to display the speed of the elevator. The main controller 113 generates the real-time speed of the elevator into the operation information to be displayed according to the electrical signals. The door controller 125 sends the received operation information to be displayed to the human-machine interaction sub-device 124, and then the operation information to be displayed is displayed through the human-machine interaction sub-device 124.

[0095] In the embodiments of the present application, the main electric control device 110 further includes a main limit device 115, and the secondary electric control device 120 further includes a door limit device 126;

[0096] The main controller 113 is connected to the main limit device 115, and the door controller 125 is connected to the door limit device 126;

[0097] The main limit device 115 is used to perform stroke limit on the cage 200 of the unmanned elevator 10;

[0098] The door limit device 126 is used to perform stroke limit on the cage door 300 of the unmanned elevator 10.

[0099] The limit device generally refers to a component that limits the movement range of the equipment. In this embodiment, the main controller 113 is connected to the main limit device 115 to perform stroke limit on the cage 200 of the unmanned elevator 10 through the main limit device 115. The door controller 125 is connected to the door limit device 126 to perform stroke limit on the cage door 300 of the unmanned elevator 10 through the door limit device 126. It should be understood that the types of the main limit device 115 and the door limit device 126 are set according to actual needs, and can be limit switches and the encoder 114, etc., which are not limited herein. For ease of understanding, in the embodiments of the present application, both the main limit device 115 and the door limit device 126 are limit switches.

[0100] When the cage 200 of the unmanned elevator 10 runs to the stroke limit position, the main limit device 115 disconnects, and the main electric control device 110 cannot control the cage 200 of the elevator. When the cage 200 of the unmanned elevator 10 runs to the stroke limit position, the main limit device 115 turns on, and the main electric control device 110 will control the cage 200 of the elevator to move upward or downward.

[0101] When the cage door 300 of the unmanned lift 10 does not reach the travel limit position, the door limit device 126 is disconnected, and the secondary electronic control device 120 cannot control the cage door 300 of the lift. When the cage door 300 of the unmanned lift 10 reaches the travel limit position, the door limit device 126 is turned on, and the secondary electronic control device 120 will control the cage door 300 of the lift to open or close. Through the main limit device 115 and the door limit device 126, it is possible to prevent the unmanned lift 10 from being damaged or causing an accident due to exceeding the safe movement range.

[0102] In an embodiment of the present application, the secondary electronic control device 120 further includes an anti-pinch limit device 127;

[0103] The door controller 125 is connected to the anti-pinch limit device 127;

[0104] The anti-pinch limit device 127 is used to perform anti-pinch limit on the cage door 300 of the unmanned lift 10.

[0105] The door controller 125 is connected to the anti-pinch limit device 127 to perform anti-pinch limit on the cage door 300 of the unmanned lift 10 through the anti-pinch limit device 127. The similarity of the anti-pinch limit device 127 is set according to actual needs and is not limited here. For ease of understanding, the anti-pinch limit device 127 in the embodiment of the present application is a limit switch.

[0106] When there is an obstacle in the movement path of the cage door 300, the anti-pinch limit device 127 is disconnected, and the secondary electronic control device 120 cannot control the cage door 300 of the lift. When there is no obstacle in the movement path of the cage door 300, the anti-pinch limit device 127 is turned on, and the secondary electronic control device 120 will control the cage door 300 of the lift to open or close. Through the anti-pinch limit device 127, it is possible to avoid the situation of the cage door 300 being mis-clamped and improve the safety of the unmanned lift 10.
