The elevator control unit and the floor control unit are both provided with wireless communication devices, and the elevator control unit is in communication connection with the floor control unit through the wireless communication devices; the communication module adopts Bluetooth communication or WiFi communication.
The elevator control unit is arranged in the elevator car and comprises an elevator controller and a positioning device; the elevator controller is used for sending a positioning instruction to the positioning device and sending a door opening instruction signal to the floor control unit; the positioning device is used for positioning the height of the elevator car according to the positioning instruction to obtain detection data and sending the detection data to the elevator controller, the elevator controller receives the detection data and outputs car height data according to the detection data, the detection data and the car height data form a one-to-one correspondence relationship, and the elevator controller judges whether door opening conditions are met according to the height data.
The floor control unit is arranged at a floor door and comprises an interlocking controller and an electric door lock; the interlocking controller is used for receiving a door opening instruction signal sent by the elevator control unit and sending a door opening instruction to the electric door lock according to the door opening instruction signal; and the electric door lock is used for receiving the door opening instruction and unlocking.
Example 2
As shown in fig. 2, this embodiment is different from embodiment 1 in that the positioning device includes two metal detectors and a reset module, and the two metal detectors are disposed at a rack of a construction elevator, and are used to detect the number of peaks of the rack passing through the positioning device, and send detection data to the elevator controller.
The reset module comprises a top layer reset switch and a bottom layer reset switch; the elevator controller adopts an STM32F767IIT6 singlechip and is respectively connected with the two metal detectors, the two reset switches and the power interface; the two metal detectors are arranged right in front of the support rack in a staggered manner along the movement direction of the construction elevator according to the vertical distance of R/4 (the space between teeth of the support rack of the construction elevator is R); the top layer reset switch and the bottom layer reset switch are respectively installed on the top layer and the bottom layer of the construction elevator car.
The metal detector adopts a TL-Q5MY1 inductive sensor which is marked as X and Y respectively; the elevator controller sends an excitation signal to the metal detector and receives signals of a tooth peak and a tooth valley which are fed back to the rack; when the tooth peak is close to the detector, the detector outputs a detection signal, the gear is far away from the detector, and the detection signal disappears. The elevator controller comprises a counter CNT by which the height coding is tracked, each count unit of the counter CNT representing a distance of 1/4R.
And (4) normal operation:
as shown in fig. 3, the controller tracks the transition edge of the XY signal to obtain a waveform, and at the rising edge of X, if Y is a negative signal, CNT adds 1: if Y is a positive signal, CNT is decremented by 1; on the falling edge of X, if Y is a positive signal, CNT is incremented by 1: if Y is a negative signal, CNT is decremented by 1; on the rising edge of Y, if X is a positive signal, CNT is incremented by 1: if X is a negative signal, CNT is decremented by 1; on the falling edge of Y, if X is a negative signal, CNT is incremented by 1: if X is a positive signal, CNT is decremented by 1; at the end of the stroke, the CNT is reset by the reset switch.
Exception handling:
1. changing direction of motion midway
The waveform received in this case is shown in fig. 4, where X (or Y) will receive an extra pulse, and the process is always kept the other path signal Y (or X) unchanged, regardless of the level of the other path, the counter first performs an addition and then a subtraction (or vice versa), and after it has moved to its original position, the CNT will remain unchanged.
2. Interference pulse received by a certain path
As shown in FIG. 5, since the gear continues to move at a relatively slow speed, and the pulse width of the electromagnetic interference is very narrow compared with the metal detector, if the pulse is positive, the CNT will instantaneously increase by one at the upper edge of the pulse, and then, the CNT will decrease by one at the negative edge of the pulse, but the device position tracking will not be influenced from a macroscopic point of view.
Example 3
As shown in fig. 6, the present embodiment is different from embodiment 2 in that the floor control unit further includes a door opening and closing detection unit; the elevator control unit also comprises an alarm and a command input device.

In the implementation process, the elevator control unit positions the height of the elevator in real time through the positioning device. When the construction elevator reaches the appointed floor, the personnel in the elevator select the door opening command in the command input device in the elevator. The elevator control unit calculates the floor number according to the real-time height and judges whether the current stop error is within an allowable range (the allowable range is within 15 cm); if the door is out of range, the door is refused to be opened; and if the error range is within the error range, sending a door opening instruction signal to the corresponding floor control unit through the wireless communication device. The floor control unit sends a door opening instruction to the electric door lock according to the door opening instruction signal; the electric door lock is used for receiving the door opening instruction and unlocking, monitoring the opening and closing information of the building door through the door opening and closing detection unit, and feeding back the opening and closing state to the elevator control unit in real time. When the elevator stops, if the door opening and closing monitoring unit feeds back that the floor door is not closed, the elevator control unit prohibits the elevator from starting until the door opening and closing monitoring unit feeds back that the floor door is normally closed.
In the running process of the elevator, data interaction can be carried out through the wireless communication device, the opening and closing states of the floor doors of 2-3 floors adjacent to the elevator in the running direction are detected, and if the floor doors are not closed in the running direction, the elevator control unit stops running and gives an alarm to the outside.
In an idle state, if the floor door is opened abnormally, the corresponding floor control unit can automatically alarm to remind constructors of timely processing, and meanwhile, the faults of the floor equipment can be found through the steps.
Example 4
As shown in fig. 7, the present embodiment is different from embodiment 3 in that a display module is added to the present embodiment based on embodiment 3.
