Detection method for stacker-reclaimer traveling encoder

Abstract

The invention relates to the technical field of detection on the running of stacker-reclaimer operation equipment, and discloses a detection method for a stacker-reclaimer traveling encoder. The detection method specifically comprises the steps as follows: step 1, a rotation frequency converter of a transmission system feeds running frequency back to a PLC controller via the Ethernet; step 2, therunning frequency of the frequency converter is converted into a traveling distance via a mathematical logic; and step 3, a mathematical logic operation result is compared with the value of the stacker-reclaimer traveling encoder, wherein a PLC program is provided with a mathematical logic operation to compute the traveling distance and a traveling encoder computation switching module. According to the method provided by the invention, the mathematical logic operation is performed in the PLC program via the running frequency feedback signal of the frequency converter, the logic operation is prevented from being damaged by the external factor, the maintenance workload is reduced, the working condition of the encoder is monitored in real time, the work reliability of the encoder is improved,and the remote central control centralized operation is achieved.

Description

technical field [0001] The invention relates to the technical field of operation control of stacker-reclaimer operation equipment, in particular to a detection method for a travel encoder of a stacker-reclaimer. Background technique [0002] The stacker-reclaimer is an important equipment in the raw material field. It is mainly responsible for the accumulation of raw materials at the end point and the reclaiming equipment at the source of raw material transportation. At present, the stackers and reclaimers in the raw material factories of iron and steel enterprises are generally operated manually on site, which has problems such as low production efficiency, heavy workload of operators on the posts, and harsh production environment on site. In order to meet the needs of enterprise development, Zhan Steel Raw Material Factory has developed a set of artificial intelligence system, and the stacker and reclaimer realizes remote central control and centralized intelligent operati...

Problems solved by technology

In the process of use, there are the following problems: 1. The RFID reader crashes for a period of time, unable to read the data, resulting in the inability to correct; 2. The RFID electronic tag is installed on the belt bracket, and the track of the stacker-reclaimer will sink, Objective reasons such as adjusting the track and the on-site environment cause the relative distance between the RFID reader and the electronic tag to exceed the sensing distance of the reader, making it impossible to read the electronic tag; 3. The workload of manual maintenance is heavy, and the phenomenon of missed reading of the electronic tag often occurs; 4. Unable to monitor encoder status in real time
