Elevator control system based on two-dimensional code recognition and antenna manufacturing method thereof

Abstract

The invention discloses an elevator control system based on two-dimensional code recognition and an antenna manufacturing method thereof, and belongs to the technical field of elevator control. The elevator control system based on two-dimensional code recognition comprises a control panel, wherein the back face of the control panel is fixedly connected with the front face of a supporting frame; and a two-dimensional code recognition module is connected to the lower part of the front face of the control panel in a clamped mode. According to the elevator control system based on two-dimensional code recognition and the antenna manufacturing method thereof provided by the invention, after the control system is installed, when the control panel is collided by external force, the control panel extrudes a baffle through the supporting frame, a connecting plate can extrude multiple sliding rods after being stressed, the multiple sliding rods drive a top plate to move forwards and extrude a plurality of hydraulic rods, a top plate can be supported through the action of internal pressure of a buffering cushion and the hydraulic rods, and meanwhile, multiple springs can effectively play a damping role after being pressed, so that the control panel and the supporting frame are prevented from being too large in vibration amplitude, and the purposes of shock absorption and buffering are effectively achieved; and an antenna is arranged in the control system, meanwhile, the antenna is prevented from being damaged, and the situation that the control system is collided, breaks down and cannot be used is avoided.

Description

technical field [0001] The invention belongs to the technical field of elevator control, and specifically relates to an elevator control system based on two-dimensional code identification and a method for making an antenna thereof. Background technique [0002] Elevator control system means that the elevator control system has gone through a process from simple to complex. The drag systems used for elevators mainly include: single-speed and double-speed AC motor drive systems, AC motor stator voltage regulation and speed regulation drive systems, DC Generator-motor thyristor excitation drive system, thyristor direct power supply system, VVVF variable frequency variable voltage speed regulation system, elevator control system hardware consists of car control panel, hall door signal, PLC, frequency converter, speed regulation system , the frequency converter only completes the speed regulation function, while the logic control part is completed by the PLC. The PLC is responsi...

Problems solved by technology

[0010] In order to overcome the above-mentioned defects of the prior art, the present invention provides an elevator control system based on two-dimensional code identification and its antenna manufacturing method, which solves the need to repeatedly adjust the position of the control device during installation and disassembly, and then adjust the position of the control device through fasteners. The position is limited, and the purpose of efficient and stable installation cannot be achieved. At the same time, the antenna and the two-dimensional code identification module set on the outer wall of the car control device are easily damaged when the control device in the car is hit by an external force, and the antenna is exposed, which poses a certain safety hazard. , is also susceptible to electromagnetic interference, which affects the normal transmission of its signals and has a certain impact on the normal use of the control device
