Abstract

(57) [Summary] [Purpose] It is possible to inexpensively manage irrigation time for multiple ridges in multiple buildings with simple operations. A combination of irrigation start time management by a plurality of 24-hour timers 1 and irrigation time control for each ridge by a plurality of interval timers 2 realizes management of a plurality of buildings by automatic switching.

Description

[Detailed description of the invention]

[0001]

[Industrial applications]

 The present invention relates to an apparatus for periodically and automatically watering plants in a greenhouse or the like.

[0002]

[Prior art]

 In greenhouse cultivation of fruits such as melons, the amount of water applied to the plants is very important.If the amount is small, sufficient growth cannot be expected, but if the amount is too large, only fruits with too much water and low sugar content are harvested. Can not. For this reason, it was necessary for farmers to frequently water the plants three to six times a day with a watering can, etc., according to the growing condition of the plants, which was a very laborious operation.

In recent years, various automatic irrigation devices have been devised in order to save these operations. One method is a centralized system in which all the greenhouses in multiple buildings are centrally controlled, including the opening and closing of windows and the control of boilers, using a single personal computer. Another method is to control irrigation using a timer individually for each building. In either case, it is fundamental to control multiple ridges in the greenhouse by changing the irrigating time for each ridge, instead of managing one building with one irrigation time.

[0004]

[Problems to be solved by the invention]

 However, among the above-mentioned systems that use a personal computer, it is difficult to introduce the system because it is costly and expensive, and it is difficult to control the computer without familiarity with the operation of the personal computer. The damage spread to all buildings, making it difficult to spread.

On the other hand, in the latter individual timer system for each house, the operation is simple and the cost per system is low, but the average melon farmer has 9 to 10 greenhouses. Therefore, the total amount was not inexpensive as a result, and it was complicated to set each of them individually.

[0006]

[Means for Solving the Problems]

 In order to solve the above two drawbacks, the present invention combines multiple 24-hour timers for controlling the irrigation start time and multiple interval timers for controlling the irrigation time for each ridge. It is characterized by doing.

[0007]

[Action]

 If the automatic irrigation apparatus having the above configuration is used, irrigation control can be simply and inexpensively realized individually for a plurality of ridges of a plurality of greenhouses in one system.

【Example】

 Hereinafter, specific embodiments of the present invention will be described with reference to the accompanying drawings. FIG. 1 is a perspective view showing the appearance of the electric control device of the present invention. FIG. 2 is a perspective view showing the appearance of the valve control device. FIG. 3 is an electric circuit diagram of a main part of the electric control device, and FIG. 4 is a piping diagram.

As shown in FIG. 1, the present invention comprises a plurality of 24-hour timers 1 and a plurality of interval timers 2. The 24-hour timer controls the start of irrigation in each greenhouse. Normally, two sets of 24-hour timers individually control the time in two greenhouses. On the other hand, the interval timer is in charge of controlling the irrigation time of each ridge. Usually, six or eight sets of interval timers control the irrigation time of the corresponding ridge.

Usually, the electric control device shown in FIG. 1 is fixedly installed on the outer wall of the greenhouse, and the valve control device shown in FIG. 2 is fixedly installed on the inner wall of the greenhouse. Then, electric power is supplied to the electric control device from a power line, water is supplied from a water pipe to the valve control device, and a watering tube connected to each ridge is connected, and the electric control device and the valve control device are connected to each other. The system is completed by electrical connection using multi-core cables. According to the present embodiment, two valve control devices are required according to the present embodiment, and two sets of the device in FIG. 2 are installed.

A main electric circuit of the electric control device is as shown in FIG. 3, and a piping route of the valve control device is as shown in FIG.

That is, when the operation time of the 24-hour timer 1a or 1b is reached, the relay CR1 or CR2 is energized, respectively, and the signal is output from the relay CR3 for specifying one of the two sets of valve control devices and the respective channels. Is sent to the start signal of the interval timer 2. As a result, in each of the solenoid valves 5, either the greenhouse A or the greenhouse B is collectively selected and the irrigation starts simultaneously.

Thereafter, when the set time of each interval timer 2 elapses, each interval timer stops energizing the corresponding solenoid valve 5, and as a result, irrigation is stopped at a different time for each channel.

The toggle switch 3 of the spring return shown in FIGS. 1 and 2 is a manually operated switch for performing irrigation at an extraordinary time different from the 24-hour timer. Alternatively, when the user tilts the valve in the desired direction B, the desired valve control device starts irrigation temporarily, and the stop is performed at the designated time of the interval timer 2 or is forcibly stopped by the stop push button switch 4.

As described above, the tap water supplied to the filters 6 of FIGS. 2 and 4 passes through the pressure regulating valve 7, then passes through the solenoid valve 5 of each channel, and passes through the water outlet 9 of each channel. Thus, the watering time and watering time are controlled and supplied to the watering tubes in each ridge.

As described above, in the description of the present invention, a specific embodiment of the present invention has been described in detail. However, the present invention is not limited to such an embodiment, and various modifications may be made within the scope of the present invention. It is clear to a person skilled in the art that the embodiments of the present invention are possible.

For example, the 24-hour timer and the interval timer may be of a type in which a plurality of timers are built in one housing, or may be controlled by a digital system instead of an analog system as in this embodiment. It does not matter.

Also, the watering time control timer may be used in such a manner that the holding circuit by the relay is activated at the start time instead of the interval timer, and the holding circuit is turned off after a specified time of the watering time.

[0019]

[Effect of the invention]

 As described above, by using the automatic watering device of the present invention described in detail, it is possible to perform automatic watering for a plurality of ridges in a plurality of buildings with one system while maintaining a simple and clear operation method. Inexpensive and efficient irrigation management can be performed.
