Satellite irrigation system controller

Abstract

The invention relates to a remote irrigation control system, more particularly to a satellite irrigation system controller with wireless control. The controller includes three parts: power, central control, and signal output. The central control part is a microprogram control unit, and an output terminal of the microprogram control unit is connected with a board address switch and a driver array. The driver array is output to a relay board through an electronic output terminal. The input port and output port of the microprogram control unit are connected with an RS485 interference as well as a real-time clock and a flash memory, and the power part provides direct-current power supply of 12V for the microprogram control unit. The satellite irrigation system controller provided in the invention has a function of directly sending a digital controlled signal to unlatch or close an electromagnetic valve for normal irrigation one by one or selectively. Therefore, pertinency for irrigation is stronger, so that the waste of precious water resource is avoided. Meanwhile, increase of manual labor and material resources brought about by cable laying can be avoided, so that the cost is substantially reduced.

Description

technical field

[0001] The invention relates to a remote irrigation control system, in particular to a wireless-controlled satellite irrigation system controller. Background technique

[0002] In terms of existing agriculture, in order to ensure the growth and development of crops, it is necessary to monitor the water demand of crops and perform real-time irrigation; in terms of urban landscaping, it is also necessary to frequently irrigate trees, flowers and plants. In modern agricultural irrigation technology, especially in some remote mountainous areas, a large amount of manpower, material and financial resources are required to irrigate some large-scale crops, which not only wastes limited resources, but also increases the cost of agricultural production and dampens the enthusiasm for agricultural production. In some existing irrigation methods, most of them adopt artificial irrigation and automatic irrigation at regular intervals. Artificial irrigation is to observe an...

Embodiment Construction

[0016] The structure and working principle of the present invention will be described in detail below in conjunction with the accompanying drawings and embodiments.

[0017] Such as figure 1 Shown is the overall structural block diagram of the present invention. The irrigation system controller includes a power supply part, a central control part and a signal output part. The central control part is a micro-program controller 1, and the micro-program controller 1 receives irrigation program instructions from the program equipment, and passes two serial One of the ports in the interface is stored in the flash memory 3 and then executes the program instructions to send electronic irrigation signals to a series of solenoid valves according to the preset irrigation time.

[0018] The output end of the microcontroller 1 is connected with a board address switch 4 and a driver array 6 , and the driver array 6 outputs to the relay board through an electronic output port 8 . An RS485...
