Abstract

The invention discloses a control method and a control device based on a self-adapted compatible trailer type of a hydraulic horizontal pushing gas filling substation. The method comprises the following steps that S1, the trailer enters into the hydraulic horizontal pushing gas filling substation, and the electronic tag of the trailer is scanned by a scanning device to obtain the electronic tag information of the trailer; S2, the scanning device transmits the obtained electronic tag information to a receiving terminal in a wireless mode; S3, the receiving terminal sends the electronic tag information to a PLC control system through RS323 serial communication; S4, the PLC control system automatically judges the number of gas cylinders carried by the trailer according to the received electronic tag information and correspondingly controlling according to the number of gas cylinders.

Description

technical field

[0001] The invention relates to the field of automation, and in particular to a control method and a control device based on an adaptive compatible trailer type of a hydraulic horizontal pushing gas substation. Background technique

[0002] Most of the semi-trailers in the market originally had 8 cans, and now several major trailer manufacturers in the market have plans to promote 6-can trailers; due to the different volumes of individual bottles in 6-can trailers and 8-can trailers, resulting in 6-can trailers It cannot be used directly on the existing hydraulic horizontal pushing gas sub-station; in addition, there is no electrical signal detection device on the trailer, so the sub-station system cannot judge whether the incoming vehicle is 6 tanks or 8 tanks. Contents of the invention

[0003] The present invention aims at at least solving the technical problems existing in the prior art, and particularly innovatively proposes a control method and contro...
