Specifically, as shown in fig. 2, an electronic tag is provided on the tape face 11, for example, a tag such as RFID technology is integrated into the tape face 11, so that each piece of the tape face 11 has a different identity. An on-line monitoring device 2 is arranged, an on-line scanner is arranged on the on-line monitoring device 2 to identify the label of the belt surface, and a metal detector is arranged to identify the clamping head of the metal belt. The handheld terminal 3 is a handheld monitoring device with a surface, a label with the surface can be identified, a worker needs to replace the two sides with the clamping heads and scans the two sides with the surface through the handheld terminal 3, then data are transmitted through wireless signals, such as WIFI, Bluetooth, a fourth generation mobile information system (4G), a fifth generation mobile information system (5G) and the like, label information is transmitted to the online monitoring device 2 or transmitted to an independent electronic device, the step S301 is triggered, and the label information of the first scanning surface obtained by scanning of the handheld terminal 3 is obtained. Since the tape surfaces have different identification information, the first use is to number each tape surface in order, 00, 01, 02, 03, 04, 05 … …, etc. Each number corresponds to different information stored in the device. Therefore, when the serial numbers of the two consecutive scan band surfaces scanned by the handheld terminal are acquired from the handheld terminal, the first scan band surface is determined according to the serial numbers. Specifically, considering that the scan zones are cyclic numbers, that is, the scan zones are numbered again in 00 after being numbered to the last one, if the numbers of two consecutive scan zones are one of the maximum number and the other of the minimum number, the scan zone with the maximum number is selected as the first scan zone, and otherwise, the smaller number of the two numbers is selected as the first number and the corresponding scan zone is selected as the first scan zone.
Then, the belt conveyor (i.e., the adhesive tape machine) is started, and step S302 is triggered, the online monitoring device 2 is controlled to scan the transmission belt 11, and the scanned belt surface is the second scanned belt surface.
Then, step S303 to step S304 are executed to calculate and determine the arrival time of the first scan strip to the online monitoring device.
Since the tape surfaces have different identification information, the first use is to number each tape surface in order, 00, 01, 02, 03, 04, 05 … …, etc. Each number corresponds to different information stored in the device. Each section has a face length of about L.
Therefore, if the first number is greater than the second number, the distance from the first scanning strip surface to the online monitoring device is calculated as: d ═ M-N-1) × L, where M is the first number, N is the second number, and L is the strip face length;
if the first serial number is smaller than the second serial number, calculating the distance from the first scanning strip surface to the online monitoring device as follows: d ═ K + M-N-1) × L, where K is the total number of tape faces, M is the first number, N is the second number, and L is the tape face length.
For example: scans were 04 and 05, i.e., the tape cartridge between them needed to be replaced. The first scan belt surface is identified as belt surface number 04. The belt conveyor (i.e., the adhesive tape machine) is started, and at this time, if the first belt surface scanned by the online scanner of the online monitoring device 2 is 02, the belt surface numbered 02 is the second scanned belt surface. The distance D of the belt chuck to be replaced from the on-line scanner can be judged according to the number 04 of the first scanning belt surface and the number 02 of the second scanning belt surface.
D＝(04-02-1)×L
The calculated time t for the tape cartridge to be replaced to reach the scanner is calculated, at which time the conveyor speed is V1.
t＝D/V1。
When No. 04 belt surface reaches the online monitoring device 2, the belt conveyor starts to decelerate, when a metal detector of the online monitoring device 2 scans a metal belt clamping head, the deceleration acceleration applied to the transmission belt is determined according to the detected speed of the transmission belt when the belt clamping head is to be replaced, and the distance from the belt clamping head to the specified position of the dismounting belt clamping head through the mounting point of the online monitoring device 2 is known as D0The speed of the conveyor belt at this time is known as V, and the deceleration acceleration a and the stop time t of the drive control device are calculated0Wherein:
Then, step S309 is executed to control the drive control device to apply the acceleration for deceleration, which is opposite to the moving direction of the transport belt, to the transport belt until the transport belt stops, and stop the tape cartridge to be replaced at the tape cartridge mounting/dismounting specifying position.
The data and the method can realize automatic position finding of the tape clamp and accurate positioning.
The worker can realize positioning only by using the handheld terminal to scan the adjacent belt surfaces at the position of the appointed belt clamping head. Accurate shutdown is realized to belt conveyor automatic control, and degree of automation is high, and the parking position is accurate. This embodiment utilizes electronic tags and handheld scanning instrument to realize treating to change and takes the dop location, utilizes on-line monitoring device to carry out the secondary location to the strap dop, realizes taking the accurate location of dop position, and the error is no longer than 10 centimeters, can provide accurate data support for the accurate parking of drive controller control.
