Detailed Description
The technical solution in the embodiments of the present application will be described below with reference to the drawings in the embodiments of the present application.
Firstly, the cableway car linkage control method provided by the embodiment of the application is applied to a cableway car linkage control system, and the cableway car linkage control system comprises an electromagnetic detection subsystem 10 and a car gate control subsystem which are arranged on a car.
Referring to fig. 1, fig. 1 is a schematic structural diagram of an electromagnetic detection subsystem according to an embodiment of the present disclosure.
The electromagnetic detection subsystem 10 comprises a magnetic memory planning device 11, a weak magnetic detection device 12 and a digital sampling workstation 13, wherein the weak magnetic detection device 12 is electrically connected with the digital sampling workstation 13.
Alternatively, the housing of the electromagnetic detection subsystem 10 may be a housing that extends axially through an opening that extends through the entire housing to allow passage of the wireline therethrough. Alternatively, the shape of the cross section of the housing perpendicular to the axial direction may be any shape such as a circle, a square, an ellipse, and the like, and the shape of the cross section of the housing perpendicular to the axial direction in this embodiment may be a circle or a square in consideration of uniform magnetization and detection of the wire rope.
The magnetic memory planning device 11 is disposed on an inner wall of the housing, and the magnetic memory planning device 11 in this embodiment may include at least one magnetic component, and optionally, the magnetic component may be a permanent magnet such as an alloy permanent magnetic material or a ferrite permanent magnetic material.
The steel wire rope is mostly made of high-carbon steel with good magnetic conductivity, and is very suitable for detection by an electromagnetic detection method, and meanwhile, the magnetic detection method has the advantages of low cost, easiness in implementation and the like, so that the weak magnetic detection device 12 is adopted for detecting the magnetic energy of the steel wire rope in the embodiment.
Alternatively, the weak magnetic detection device 12 in the present embodiment may be a weak magnetic detection sensor. It should be understood that the number of the weak magnetic detection sensors in the present embodiment may be any number determined according to the detection requirement, such as 1, 3, 6, 8, etc.
In order to improve the detection perfection and uniformity of the weak magnetic detection device 12 on the steel wire rope, the weak magnetic detection device 12 in this embodiment is arranged around the central axis of the housing, i.e. around the axial center (the central point of the cross section perpendicular to the axial direction of the housing).
The digital sampling workstation 13 is configured to process the magnetic field information obtained by the weak magnetic detection device 12 in this embodiment, determine whether the steel wire rope corresponding to the outbound car mounting point at the current time is in the joint area based on the magnetic field information, and simultaneously electrically connect with the car gate control subsystem, so as to send a determination result signal indicating whether the steel wire rope corresponding to the outbound car mounting point at the current time is in the joint area to the car gate control subsystem, so that the car gate control subsystem controls car mounting.
Optionally, the digital sampling workstation 13 may also be connected to a stroke metering device for determining the current specific position of the steel wire rope.
The cableway car linkage control system can be installed at an upper station and a lower station of a cableway, a proper position is selected on a steel wire rope at an incoming side for installation, a car gate is at an outgoing side, and the steel wire rope firstly passes through the cableway car linkage control system and then passes through the car gate.
Corresponding to the above-mentioned cableway car linkage control device, the present embodiment provides a cableway car linkage control method, please refer to fig. 2, and fig. 2 is a schematic flow chart of the cableway car linkage control method provided in the present embodiment. The concrete steps of the cableway car linkage control method can be as follows:
step S12: the lift car gate control subsystem receives a lift car mounting signal which is used for indicating the lift car to carry out mounting.
Optionally, the car-mounted signal may be generated by a car gate control subsystem or other control modules according to a preset car start-stop position or user triggering.
Step S14: and detecting electromagnetic signals of the steel wire rope corresponding to the outbound car mounting point through an electromagnetic detection subsystem.
It should be understood that, in order to improve the detection efficiency and timeliness of the electromagnetic detection subsystem on the steel wire rope, the electromagnetic detection subsystem in this embodiment may perform joint area detection on the steel wire rope in real time 24 hours all day long.
Specifically, step S14 may include the following sub-steps:
step S141: and magnetizing the steel wire rope corresponding to the outbound car mounting point through a magnetic memory planning device.
Step S142: and acquiring the magnetic field information of the steel wire rope through a weak magnetic detection device.
Step S143: the magnetic field information is sent to a digital sampling workstation.
The digital sampling workstation processes the magnetic field information, and therefore whether the steel wire rope corresponding to the current outbound car mounting point is in the joint position or not is determined based on the magnetic field information.
Referring to fig. 3, fig. 3 is a schematic flow chart illustrating a step of identifying a position of a steel wire rope joint according to an embodiment of the present disclosure, where the step of identifying the position of the steel wire rope joint may be as follows:
step S151: the magnetic field information is converted to a waveform map by a digital sampling workstation.
Step S152: in the wave crests and the wave troughs in the oscillogram, wave crests and wave troughs with the adjacent peak-to-valley fall values belonging to a preset range value are respectively selected as effective wave crests and effective wave troughs.
Because the magnetic field information collected by the weak magnetic detection device includes the damage information, the interference information, the joint region magnetic field information, the non-joint region magnetic field information, and the like of the steel wire rope, and the corresponding oscillogram correspondingly includes the damage information, the interference information, the joint region magnetic field information, the non-joint region magnetic field information, and the like of the steel wire rope, the selection of the effective wave crest and the effective wave trough needs to be performed on the oscillogram in this embodiment, and the invalid interference information affecting the judgment of the joint region is filtered through the step S152.
According to the characteristics of the steel wire rope joint, effective information is selected through the preset range value, and therefore filtering of invalid interference information is achieved.
Specifically, step S152 may include the following sub-steps:
step S1521: and determining a preset range value from the oscillogram, wherein the preset range value is a range value taking the difference value of the wave crest and the wave trough in the oscillogram corresponding to the magnetic field information at the broken end of the steel wire rope as the center.
It should be understood that the actual value of the peak-to-valley fall in the joint area of the steel wire rope is the value of a break of the steel wire rope, and in consideration of the error and the like, the error of the preset range value in the embodiment may be 50%, that is, the error is set to be 0.5 times to 1.5 times of the peak-to-valley fall difference value.
Step S1522: and comparing the peak-valley fall difference value of every two adjacent peaks and valleys in the oscillogram with the corresponding preset range value, and taking the peaks and valleys of which the peak-valley fall difference value belongs to the preset range value as the effective peaks and effective valleys of the oscillogram.
Step S153: and calculating the average value of the distances between the effective peaks or the effective valleys.
Optionally, the effective trough or effective peak spacing is used for average calculation, which can be determined by the magnetic field magnetizing direction and the magnetic field information collecting direction, and if the two directions are the same, the more reliable effective peak spacing can be used for average and subsequent calculation, otherwise, the more reliable effective trough spacing is used for average and subsequent calculation.
Step S154: and when the effective wave crests or the effective wave troughs with the preset number meeting the judgment condition continuously appear, determining the position meeting the judgment condition as the joint area of the steel wire rope, wherein the judgment condition is that the distance between every two adjacent effective wave crests or effective wave troughs is smaller than the sum of the average value and the distance between the two long and short rope lap joint points of the steel wire rope.
The steel wire rope is generally formed by weaving a plurality of strands of steel wires, so that a plurality of broken end information is generally arranged at a joint, for example, when the steel wire rope is formed by weaving 3 strands of steel wires, magnetic field information corresponding to 3 broken end positions can be detected in a joint area, the number of corresponding effective wave crests or effective wave troughs is also 3, and therefore the identification of the joint area is standardized according to the preset number, and the identification accuracy of the joint area is improved.
The average value of the distances between the effective wave crests or the effective wave troughs represents the average value of the distances between each breakpoint on the steel wire rope, the lapping of the two long and short ropes is considered when the joint of the steel wire rope is woven in the joint area, and the distance between the breakpoints of the joint area does not exceed the sum of the average value between the breakpoints and the distance between the lapping points of the two long and short ropes of the steel wire rope, so that whether the effective wave crests or the effective wave troughs belong to the joint area or not can be judged according to the relation.
The distance between the two long and short rope lap joint points of the steel wire rope refers to the distance between the long rope and the short rope of the steel wire rope (the same joint) after the long rope and the short rope are woven on the steel wire rope.
Step S16: when the electromagnetic signal indicates that the steel wire rope is in the joint area, the car gate is controlled to be in a closed state through the car gate control subsystem, and the car is prevented from being mounted in the joint area.
The elevator car gate control subsystem prohibits the elevator car from being mounted when the enclasping device mounting point corresponds to the joint area of the steel wire rope, so that the potential safety hazard is avoided.
Further, after step S16, if the car latch has already passed through the joint area of the wire rope, the car can be immediately mounted, so in this embodiment, it is necessary to continuously perform electromagnetic signal detection on the wire rope corresponding to the outbound car mounting point by the electromagnetic detection subsystem, and when the electromagnetic signal indicates that the wire rope is in the non-joint area, the car gate control subsystem controls the car gate to be in the open state and controls the car to be mounted in the non-joint area.
Optionally, in order to ensure that the steel wire rope joint area completely passes through the car gate and then triggers the gate to open, this embodiment may have a signal delay triggering function, and according to a distance between a known weak magnetic detection device and the car gate, the delay time is automatically calculated, and the gate is opened after delaying, so as to ensure that the steel wire rope joint area completely passes through the car gate and then triggers the gate to open.
In order to cooperate with the above-mentioned cableway car linkage control method, an embodiment of the present application further provides a cableway car linkage control device 30, please refer to fig. 4, and fig. 4 is a schematic block diagram of the cableway car linkage control device provided in the embodiment of the present application.
The cableway car linkage control device 30 includes:
the mounting signal receiving module 31 is used for receiving a car mounting signal through the car gate control subsystem, and the car mounting signal is used for indicating the car to carry out mounting;
