[Abstract]:Greenhouse pot flower array platform (The Arrange Buffer Belt),) is a kind of facility gardening intelligent equipment. It is mainly used to arrange pot flowers in the transportation mode of forklift truck in greenhouse, and it can also be used as a fully automatic equipment to adjust the spacing of potted flowers. With the development of greenhouse automation production, the use of potted flower array platform has been favored by more and more enterprises. The hardware base of this study is the greenhouse pot array platform. The parameter calculation of the driving element and the selection of the driving equipment, the hardware design and software programming of the control system are carried out according to the test-bed. The design of the control program is mainly realized by GX-developer, which controls the frequency converter, encoder, motor, cylinder and so on. The hardware design of the system consists of two parts. The control module is realized by Mitsubishi FXls series programmable controller (PLC). The motor control module is realized by using EDS1000 series inverter of easy Energy Company and E6HZ-CWZ series rotary encoder of OMRON Company. Among them, programmable controller control module is used to complete the device drive, data processing, converter and encoder combination module is used to complete the motor control and parameter adjustment; The program design of the control system includes the analysis of logic, the flow design of each independent part and the program design of the concrete realization. The test results show that the greenhouse pot-flower array platform test-bed can arrange the pot flowers accurately. The precision range of the large-platform conveyor belt array is-10 mm ~ 8 mm, and the precision range of the pre-arrangement conveyor belt is-5 mm ~ 4 mm, which is less than the allowable error of forks of 30 mm. The actual productivity is 2250 basin / hour, and the highest productivity is 4090 basin / hour. Based on the combination of PLC, frequency converter and encoder to control the greenhouse pot flower array platform, it has a great advantage in the arrangement of pot flowers and the adjustment of the spacing of pot flowers during the growth process in the greenhouse. In addition, the array platform has significantly improved the efficiency and accuracy compared with most of the manual arrangement of potted flowers in China at present. At the same time, compared with the array platform imported from abroad, the array platform has the advantages of high cost-to-performance ratio and independent intellectual property rights. More suitable for domestic greenhouse small and medium-sized production needs and other characteristics.
