Fork lift three-dimensional garage

1. Mechanical structure

1 The overall model and mechanical structure are reduced by a certain ratio with the actual garage, so that students can use it in a real environment.

2 The transmission adopts the structure of gears, chains, pulleys and slide rails.

The frame is made of steel

Dimensions: length 1036mm, width 900mm, height 1880mm

Car model size: length 420mm, width 185mm, height 195mm

Wireless remote control, manual control operations into and out of the library

3 Use the lifting method to move the car up and down to the parking area composed of a multi-layer structure

4 The parking spaces are composed of two rows and five floors, which can be moved left and right. Each parking space is equipped with dual protection of machinery and sensors

5 Store and retrieve vehicles, using a fork-type exchange system

6 In and out of the vehicle, with built-in turntable structure, no need to reverse

7 This system uses up and down exchange, adopts AC gear motor

8 Lifting positioning, using Hall sensor positioning

9 Whether there is a vehicle in the parking space or not, the photoelectric reflection sensor is used to identify

10 Power supply AC220V, total power 500W

Second, the control structure

This system uses the "dual control one network" system

1 PLC control system, using S7-200 (CPU226) plus 2 EM223 expansion modules and a CPU243 Ethernet communication module, connected to Ethernet through a router

2 SCM control system adopts AT89S52 of 51 series to connect to Ethernet through router

3 Multiple PCs control the garage through Ethernet

4 The overall electrical control part is installed on the experimental mesh plate with clear layers

The overall size of the electric control mesh plate: height: 1900mm, width 640mm

Peripheral POS toll machine and automatic barrier unit can easily access this system

5 The teaching local area network is formed by Ethernet, and multiple computers use different control methods to control the lifting three-dimensional storage garage. Students and teachers can communicate through the local area network. Students can basically understand and master the basic means of modern control through this system和 方法。 And methods. Teachers can achieve remote monitoring of various compilation levels of students through intercommunication, and make full use of one device and multiple control methods to enable students in a class to control and experiment at the same time.
