specifically, as shown in fig. 2, the elevator control system includes an elevator master control, a car roof of an elevator car, a door machine controller, and a light curtain, which are connected in sequence, and data or commands can be transmitted between two adjacent devices.
In addition, the inventor of the present solution also considers that in the current general elevator control system, the light curtain needs to be configured with a power supply box separately, which increases the product cost, requires an additional installation position, is time-consuming and labor-consuming, and occupies an additional space, and for this reason, in the present solution, the door machine controller is provided with a direct current power supply for this situation; the direct current power supply is connected with the light curtain to provide electric power for the light curtain.
In a specific embodiment, the "sending a first signal to a door controller after the light curtain generates the first signal based on the detected occlusion" in step 101 includes:
when the light curtain detects that the receiving tubes are blocked, determining the number of the blocked receiving tubes;
when the number of the receiving tubes is larger than a preset value, generating a first signal;
and sending the first signal to a door machine controller through the light curtain.
Specifically, it is considered that it is necessary to prevent people from being clamped when shielding generally occurs, in this case, the light curtain should have a certain length when being shielded, that is, the receiving tubes of the light curtain have a certain amount of information that cannot be received by the transmitting tubes of the light curtain, and also represent that the transmitting tubes have a certain amount of shielding, for example, the number of the receiving tubes of the shielded light curtain reaches more than 10 (a specific preset value may be set according to experience or experiment), and in order to avoid an abnormal operation caused to the elevator by excessive sensitivity, the generation of the first signal is triggered when the number of the shielded receiving tubes reaches the preset value, and a subsequent process is started.
102, executing the operation of decelerating the gantry crane to zero through the gantry crane controller based on the first signal, and simultaneously converting the first signal into a second signal;
in a specific embodiment, the "performing, by the gantry crane controller, the operation of decelerating the gantry crane to zero based on the first signal" in step 102 includes:
executing the speed reduction operation of the gantry crane through the gantry crane controller based on the first signal so as to stop the gantry crane within a preset time; the preset time is less than or equal to the time from the time when the door machine controller starts to convert the first signal into the second signal to the time when the door machine controller receives the door opening signal.
Specifically, the speed of the deceleration operation is controlled, so that the time of the door motor for reducing the zero speed is basically equal to the time of a processed door opening signal to the door motor, and compared with the existing scheme, the reverse door opening is realized at a higher speed, and the human clamping phenomenon caused by slow light curtain reaction is solved.
In yet another specific embodiment, the "performing, by the gantry crane controller, the operation of decelerating the gantry crane to zero based on the first signal" in step 102 includes:
and controlling a motor of the gantry crane to execute an operation of decelerating to zero through the gantry crane controller based on the first signal so as to decelerate the gantry crane along with the deceleration of the motor until the gantry crane stops.
Specifically, the speed reduction of the gantry crane is realized by reducing the speed of a motor of the gantry crane.
103, sending the second signal to the car top plate through the gantry crane controller;
specifically, the second signal may be the same as the third signal, i.e., the car roof board performs the function of forwarding the signal to the elevator master control.
105, sending the door opening signal to the door operator controller through the car roof plate;
and 106, executing the reverse door opening operation of the door operator through the door operator controller based on the door opening signal.
Specifically, as shown in fig. 2, in the present solution, the light curtain cable is directly connected to the door controller, the door controller provides an independent dc power supply for the light curtain, the light curtain directly provides an action signal to the door controller, and the door controller processes the action signal and converts the action signal into an output signal.
In the process of needing the door closing of the door machine, the signal processing process of the light curtain is to transmit a signal to the door machine controller when the light curtain acts, and the door machine controller controls the motor to reduce to zero speed after receiving the signal; simultaneously transmitting the signal to the car top plate;
the car roof transmits the signal to the elevator master control, the door opening signal is transmitted to the car roof after the master control is processed, the door opening signal is transmitted to the door operator controller by the car roof, and the door operator controller reversely opens the door after receiving the door opening signal.
In the process, the time for the door control motor to reduce to zero speed is basically equal to the time for the processed door opening signal to the door operator, so that the light curtain action door operator can immediately and reversely open the door, and the human clamping phenomenon caused by slow light curtain reaction is avoided.
