Novel greenhouse intelligent transportation platform control system

Abstract

The invention provides a novel greenhouse intelligent transportation platform control system, and the system comprises vehicle side distance measurement sensors, vehicle front and back distance measurement sensors, and a controller. The vehicle side distance measurement sensors consist of two distance measurement sensors on front and back surfaces of a vehicle body, and the measurement sensors are used for measuring the distance between the platform and an in-greenhouse reference object. The vehicle front and back distance measurement sensors are used for detecting the distance between the platform and an operator or a barrier. The controller carries out the following control according to the detection values of the sensors: judging the deflection of the vehicle according to the detection values of the front and rear distance measurement sensors, and regulating and controlling a steering motor to change direction; and adjusting the state of a walking motor when the values detected by the front and back distance measurement sensors change and exceed a preset distance threshold value, so as to achieve the accelerating and decelerating following or parking for waiting for returning operation of the operator. Compared with the prior art, the system reduces the requirements for a user for using a remote controller, and brings convenience to in-greenhouse production activities.

Description

technical field [0001] The invention relates to the field of agricultural machinery, and specifically designs an intelligent transportation platform control system suitable for carrying out intelligent transportation operations in greenhouses. Background technique [0002] At present, during the development of facility agriculture in our country, the problem of transportation of working materials in the shed has emerged. Now the greenhouse growers generally carry the working materials in the shed by shoulders and hands. Due to the airtight and stuffy space in the shed, the transportation Materials often reach 50-100 kilograms, and the operation is very hard. How to transport chemical fertilizers, small farm implements, and harvested fruits and vegetables mechanized, conveniently and efficiently on a 50-centimeter-wide working path has become an urgent problem to be solved in the development of facility agriculture. [0003] Some companies in the industry are also trying, an...

Problems solved by technology

These transportation schemes can indeed solve some problems in terms of labor saving, but they all have certain disadvantages: the transportation of hand-push electric vehicles takes up a manpower, that is, the role of the pusher, and the operator needs to temporarily act as the pusher, or arrange one alone

The disadvantage of the rail car is that the greenhouse grower needs to install rail devices in several greenhouses he manages, and the transport vehicle may only be used in one greenhouse, which not only requires a large investment, but is also very inconvenient

[0004] The above-mentioned existing solutions on the market cannot better meet the operational needs of greenhouse growers due to the flaws in their design concepts.
