Method for controlling traveling positioning device positioned on gate type scraper material taking machine by applying radio frequency identification technology

Abstract

The invention relates to a method for controlling a traveling positioning device positioned on a gate type scraper material taking machine by applying a radio frequency identification technology, which is used for a material taking machine detection industry. The method is characterized in that the actual position of the gate type scraper material taking machine is accurately judged by applying the identification capability of the radio frequency identification technology; the existence of loss of signals is detected through logic judgment; the automation degree of the control of the gate type scraper material taking machine is increased, and the protection grade of the integral machine is enhanced; the contents of different labels are read to obtain different information by detecting the different labels when equipment is moved; a design cycle is shortened, and the automatic control level is enhanced; data passing through an RFID (Radio Frequency Identification Devices) is read through a PLC (Programmable Logic Controller) on an assigned position by matching the traveling positioning device with a traveling coder so as to obtain an actual position value; and the actual position value is written into the traveling coder to achieve the purpose of enhancing the accuracy of a traveling position. The method has easy installation performance, accurately judges the actual position of the gate type scraper material taking machine and enhances the positioning accuracy of the equipment, the generalization of the equipment, the protection grade of the integral equipment and the automatic control level.

Description

technical field [0001] The invention relates to a method for controlling a walking positioning device on a door-type scraper reclaimer by using a radio frequency identification technology for detecting the stacking position of a reclaimer. Background technique [0002] The portal scraper reclaimer is a kind of material conveying equipment used in long stockyards. The equipment door frame is installed on two horizontal tracks, one track is laid on the ground, and the other is laid on the retaining wall. The door frame There is a hoist installed on the top, which is more suitable for the use of materials stacked in multi-stack bins. The equipment walks along the track and moves to the designated stacking point through the walking drive to complete the reclaiming process of different materials. In electrical control, the discrimination of different stacking points and positioning points is one of the very important links of this kind of mobile equipment. In the past, there ar...

Problems solved by technology

The first two methods have common disadvantages: first, the collision distance of the switch head does not exceed 3.5CM, and the sensing distance of the proximity switch is only 1.5CM, and there is a longitudinal displacement of the equipment on the track, which is easily not sensed; second, it is inconvenient to install , multiple switches need to be installed on the device to meet the requirements; third, the protection level is relatively low, and the installation protection level at the connection with the cable can only reach IP5x, and the protection level of RFID is IP67

The third method also has disadvantages: first, it is inconvenient to install, because the reclaimer has a displacement in the horizontal direction. If the distance is long, the area of ​​the reflective plate is required to be large; second, the material of the reflective plate can be replaced by many materials, and many The material is also used on the clothing, which leads to the possibility of occlusion, resulting in false signals
