Description

Bus control type water and fertilizer integrated machine

Technical Field

The utility model relates to an agricultural fertilization irrigation facility technical field, concretely relates to bus control type liquid manure all-in-one.

Background

In the current modern agriculture high-speed development period of China, modern precision agricultural equipment represented by a water and fertilizer all-in-one machine is rapidly popularized, a water and fertilizer all-in-one machine system is divided into three parts according to functions, the first part is an electrical proportioning system, the second part is a fertilizer mixing system, and the third part is an irrigation control system of a subordinate irrigation area.

At present, a common liquid manure all-in-one machine control part is mainly controlled by a Programmable Logic Controller (PLC), the controllable number of ways is limited by the production model of a PLC manufacturer, if the selected PLC model is a model with 10 ways of digital quantity input/10 ways of relay output, if the corresponding number of ways is used up, an additional expansion module can only be added, the additional expansion module is relatively expensive, meanwhile, peripheral electrical equipment (a relay, a contactor and the like) is also required to be added, generally, a processed control box cannot be added with other equipment, and only the control box can be manufactured again.

The equipment that ordinary liquid manure all-in-one needs control includes: a main water pump, a fertilizing tank stirrer 3, a fertilizing pump electromagnetic valve 3, an irrigation area electromagnetic valve and the like. The general fertilizer applicator mainly needs to control the objects, only basic equipment needs to be controlled, the PLC has the function of 9-path relay output, and if a plurality of irrigation areas need to be controlled by the electromagnetic valves, corresponding expansion modules need to be added. In addition, if the existing fertilizer applicator needs to control the sub-irrigation areas below, one irrigation area needs to correspond to one path of relay output, and if 10 irrigation areas need to be controlled below one water and fertilizer all-in-one machine and one electromagnetic valve is arranged in each irrigation area, namely, a 10-path output module and a corresponding peripheral circuit need to be added on the original basis, the equipment volume is very large, and the cost is greatly increased. If there are too many irrigation areas (more than 20) to be controlled, it is already substantially difficult for existing installations to meet these requirements. And if the fertilizer applicator needs to control a large number of irrigation areas (more than ten), an electric circuit of the traditional water and fertilizer all-in-one machine is quite complex, and profit margin and use value are basically lost.

3. the equipment profile frame is complex: the control cabinet is required to be installed, and the position for installing the control cabinet is required to be reserved specially for the section frame of the water and fertilizer integrated machine, so that the complexity of the frame is increased, and the cost of the section frame increased by installing the control cabinet accounts for about 30% of the total cost of the section;

4. the equipment controls the slave station to have less capacity: the number of the electromagnetic valves in the field can be controlled by the equipment, the equipment depends on the input and output points of plc in a selected area, and once the equipment is installed, the plc is difficult to replace at a later stage, namely the number of the controllable electromagnetic valves cannot be basically expanded;

5. the equipment installation cost is higher: because a communication control bus technology is not used and control is required according to the number of lines, one electromagnetic valve is required to be connected with one electric wire to the control cabinet, and the total length of the electric wire is very long;

6. the device communication distance is short: the communication distance is about 200-400 meters generally, if the distance is too long, the end voltage of the electromagnetic valve is too low, and the electromagnetic valve cannot be controlled because the end voltage does not reach the starting voltage;

7. there is polarity when installing: when the device is installed, the wiring of the anode and the cathode needs to be noticed, if the connection is incorrect, the device is short-circuited or burnt, and the safety of the device is seriously influenced.
