Description

Technical Field

[0001] This utility model relates to the technical field of elevators, and in particular to a control system for an intelligent elevator. Background Technology

[0002] A lift is a mechanical device that can move vertically and is mainly used for lifting, handling and transporting goods in buildings, warehouses, factories and other places.

[0003] The elevator uses a combination of mechanical structures such as levers, gears, ratchet, wire ropes, and springs to transmit power and control movement. During operation, the operator cranks a lever, which rotates the gear set. The gears then drive a lead screw or rack. As the lead screw rotates, the nut (fixed to the platform) moves axially along the lead screw, causing the platform to rise.

[0004] In the process of controlling the elevator, the elevator's ascent and descent require manual force to drive it, which makes the operation of the elevator time-consuming and labor-intensive. Utility Model Content

[0005] To improve the convenience of using the elevator, this utility model provides a control system for an intelligent elevator.

[0011] By adopting the above technical solution, the operation of the elevator is automatically controlled by the activation trigger module and the control module, and the operation of the elevator is stopped in time by the limit trigger module. This can improve the operating efficiency of the elevator, make the lifting speed less susceptible to changes in human output force, improve the stability of the elevator operation, and improve the safety of using the elevator by stopping the elevator in time when abnormalities occur.

[0022] Optionally, it may also include a locking module connected to the control module to receive an up control signal or a down control signal and not lock the elevator in response to the up control signal or the down control signal.

[0023] Optionally, it also includes a power supply module for supplying power to the start-up trigger module, the limit trigger module, the control module, and the operation module.

[0024] Optionally, the power module includes:

[0025] The power supply unit is used to supply power to the power module.

[0026] The protection unit is used to protect the power supply circuit of the elevator.

[0027] Optionally, the power module further includes a filtering unit connected to the protection unit and used to filter the protection unit.

[0028] Optionally, it may also include a step-down unit connected to the power module to reduce the voltage of the power module.

[0029] Optionally, a stabilizing unit may also be included, connected to the step-down unit, to ensure the stability of the converted voltage and reduce voltage fluctuations and ripple.

[0030] In summary, this utility model has at least one of the following beneficial technical effects:

[0031] 1. The elevator operation is automatically controlled by the start-up trigger module and control module, and the elevator operation is stopped in time by the limit trigger module.

[0049] The present invention will now be described in further detail with reference to the accompanying drawings and embodiments.

[0050] This utility model discloses a control system for an intelligent elevator.

[0051] Example 1: Refer to Figure 1 A control system for an intelligent elevator includes a start trigger module 1 for outputting a start detection signal and a limit trigger module 2 for outputting a limit detection signal.

[0052] Reference Figure 1 The start-up trigger module 1 includes an upward trigger unit 11 and a downward trigger unit 12. The upward trigger unit 11 outputs an upward start signal, and the downward trigger unit 12 outputs a downward start signal. The upward trigger unit 11, the downward trigger unit 12, and the control module 3 are connected. The control module 3 receives the upward or downward start signal and, in response, closes the power supply circuit to drive the elevator to rise or fall. The limit trigger module 2 is connected to the control module 3. The control module 3 receives a limit detection signal and, in response, disconnects the power supply circuit to stop the elevator.

[0053] Reference Figure 1The rising trigger unit 11 includes a normally open switch S1-1 and a synchronous normally closed switch S1-2, the falling trigger unit 12 consists of a normally open switch S2-1 and a synchronous normally closed switch S2-2, the limit trigger module 2 is a normally closed switch S3, and the control module 3 is a DJ03 motor M with power failure lock-up.

[0054] Reference Figure 1 One end of normally closed switch S3 is connected to power supply VCC. The other end of normally closed switch S3, one end of normally open switch S1-1, and one end of normally open switch S2-1 are connected together. The other end of normally open switch S1-1, the other end of normally open switch S2-1, and one end of motor M are connected together. The other end of motor M, one end of synchronous normally closed switch S1-2, and one end of synchronous normally closed switch S2-2 are connected together. The other ends of synchronous normally closed switches S1-2 and S2-2 are connected to ground GND. In this embodiment, normally open switches S1-1 and S2-1 are toggle switches, and normally open switches S1-1 and S2-1 cannot be opened and closed simultaneously. Normally closed switch S3 is a self-resetting button.

[0055] The working principle of Example 1 is as follows: When the user needs to control the elevator to rise, the normally open switch S1-1 is closed, the synchronous normally closed switch S1-2 is opened, the synchronous normally closed switch S2-2 is not opened, the power supply circuit between power supply VCC and motor M is closed, the current is conducted, and motor M rotates forward to drive the elevator to rise.

[0056] When the user needs to control the elevator to descend, the normally open switch S2-1 closes, the synchronous normally closed switch S2-2 opens, and the synchronous normally closed switch S1-2 remains open. The power supply circuit between the power supply VCC and the motor M is closed, and the current through the motor M is reversed, causing the motor M to reverse and drive the elevator to descend.

[0057] When the user needs to control the elevator to stop, the normally closed switch S3 opens, the synchronous normally closed switch S2-2 does not open, the synchronous normally closed switch S1-2 does not open, the power supply VCC is disconnected from the power supply circuit of the normally open switch S2-1 and the normally open switch S1-1, the motor M does not have current and does not rotate, the elevator stops running and locks itself.

[0059] The operation module 4 includes a lifting operation unit 41 for controlling the elevator's ascent and a lowering operation unit 42 for controlling the elevator's descent. The locking module 5 is connected to the control module 3; when the control module 3 does not output a control signal, the elevator stops operating, and the locking module 5 locks the elevator. The power supply module 6 includes a power supply unit 61 for supplying power to the power supply module 6, a protection unit 62 for protecting the power supply circuit of the elevator, and a filter unit 63 connected to the protection unit 62. A step-down unit 7 is connected to the power supply module 6 to reduce the voltage of the power supply module 6, and a stabilizing unit 8 is connected to the step-down unit 7 to stabilize the voltage.

[0101] The implementation principle of the intelligent elevator control system of this utility model embodiment is as follows: when the rising trigger unit 11 or the falling trigger unit 12 outputs a rising start signal or a falling start signal, the control module 3 receives the rising start signal or the falling start signal and responds to the rising start signal or the falling start signal to output a rising control signal or a falling control signal to drive the elevator to rise or fall.

[0102] When the locking module 5 receives the lifting control signal, the lifting locking unit 51 receives the lifting control signal and responds to the lifting control signal to release the brake, so that the elevator can rise. The lifting operation unit 41 receives the lifting control signal and responds to the lifting control signal to control the elevator to rise.

[0103] When the locking module 5 receives the descent control signal, the descent locking unit 52 receives the descent control signal and responds to the descent control signal to release the brake, and the elevator can descend.

[0104] When the limit trigger module 2 outputs the limit detection signal, the control module 3 receives the limit detection signal and does not output the rising control signal or the falling control signal, but outputs the limit control signal. The running module 4 does not close the power supply circuit, the elevator stops running, and the locking module 5 does not receive the control signal to control the brake operation and lock the elevator position.

[0105] When the voltage detection module 9 and the current detection module 10 detect an abnormal current or voltage in the control module 3, the control module 3 does not output a control signal, the operation module 4 does not close the power supply circuit, the elevator stops running, and the locking module 5 does not receive a control signal to control the brake operation and lock the elevator position.

[0106] When the control module 3 receives the start detection signal, the limit detection signal, the control signal output by the control module 3, or when the current or voltage of the control module 3 is abnormal, the prompt module 13 and the display module 14 trigger the buzzer to sound and start the light.
