However, the above-mentioned plant stem diameter measuring device has a complicated structure and a considerable weight as a whole. Plants to which such a heavy measuring device can be attached have a problem that the trunk is hard and the whole body including the root is limited. That is, the measuring device is not only applicable to soft or thin trunks or stems, but even if it can be worn,
There was a problem that the mounting by the fixing means was troublesome.

Further, even if the water content in the plant can be measured by the above-mentioned plant stem diameter measuring device, the drainage of the plant was observed by the agricultural worker, and the timing of water supply and drainage was measured based on this result. . This timing has a problem that it depends on the experience or intuition of the farmer in many cases. In addition, for plant cultivation, light environment, temperature environment,
There are many factors such as the rhizosphere environment (water around the roots, nutrients, temperature, soil properties, etc.), and the factors are complicatedly related. Therefore, plant cultivation often depends on the experience and intuition of the farmer. In particular, the time for draining plants was difficult and it was difficult to automate.

Moreover, emergency call systems make simple messages or just calls. However, each of the above systems uses remote sensing technology and is used, for example, in plant facilities,
It is a collection of advanced technologies. When such advanced technology is used for agricultural facilities such as a vinyl house, there is a problem that facility costs and management costs are high, and the profitability of the harvested products is not suitable.

Further, in the cultivation of plants or the draining cultivation of plants, if the supply of water and / or nutrients is simply stopped, the abnormality information cannot be output.
That is, the sensor for detecting the presence or absence of water has a problem that it is not suitable for cultivating a plant accompanied by drainage, because when the supply of water and / or nutrients is stopped, the sensor detects the fact and generates abnormal information.

The present invention is intended to solve the above problems, and an object thereof is to provide a plant cultivation system capable of automating the cultivation of plants. Another object of the present invention is to provide a plant drainage system that can obtain plant growth or fruit harvest by optimally draining plants. Another object of the present invention is to provide a fault information transmission system for transmitting fault information suitable for plant cultivation or plant drainage cultivation to subscribers by a simple facility.

FIG. 6 is a diagram for explaining an example in which the plant draining system is applied to hydroponic cultivation in an embodiment of the present invention. For example, the plant 61 is cultivated by placing rock wool (rock wool) on the hydroponic cultivation bed 62, for example. Further, the hydroponic cultivation bed 62 is inclined so that the hydroponic solution 63 flows at a predetermined speed. On the hydroponic cultivation bed 62, a water supply pipe 64 for supplying the hydroponic liquid 63 to one side and a first drainage pipe 65 mounted at a low position are attached. In the hydroponics nutrient solution tank 66, the water supply pipe 64 for supplying water is
It is connected to the hydroponic cultivation bed 62 via the water supply pump 67 and the first valve 68. Further, when the first valve 68 in the water supply pipe 64 is closed, a second drain pipe 65 ′ for returning the hydroponic solution 63 to the original hydroponic culture solution tank 66 is connected via the second valve 69. Has been done.

The above hydroponics system is used for the plant 6
The computer 44 calculates the amount of the hydroponic liquid 63 or the draining time thereof based on the information from the in-plant water content measuring sensor 42 attached to No. 1 and the information in the draining cultivation database 433.

The second valve 69 is opened, and the hydroponic solution 63 is returned from the second drain pipe 65 'to the original hydroponic solution tank 66. In this way, the hydroponic cultivation system uses the data stored in the drainage cultivation database 433 to indicate the supply amount of the hydroponic solution that differs for each plant, or the timing of draining that differs for each plant. Based on the calculation, the hydroponic solution can be put into an optimum state.

FIG. 7 is a diagram for explaining another example of the present invention in which the drainage system for plants is applied to soil cultivation. The soil cultivation in this example is suitable for greenhouse cultivation in which plants are covered with vinyl or the like, but can also be applied to plants that are not house-cultivated or plants that are covered for a certain period of time. For example, the plant 71 is cultivated in the soil 72. Water 74 is stored in the water storage tank 73, and is connected to a water sprinkler (not shown) via a water supply pipe 75. Also, the water supply pipe 75
A water supply pump 76 and a valve 77 are connected to. Then, the computer 44 performs calculation based on the information from the drainage cultivation database 433 and the in-plant water content measuring sensor 42. After that, the control signal calculated by the computer 44 operates the relay output circuit 51 to open and close the valve 77 to control the sprinkling timing and amount of the sprinkler. In this way, the soil cultivation system is based on the data stored in the drainage cultivation database 433 regarding the water supply amount that differs depending on each plant or the draining time that varies depending on each plant. It can be calculated and the water content can be optimized. Further, in this embodiment, water is stored in the water storage tank and sprinkled, but a nutrient solution containing nutrients may be used instead of water.

FIG. 8 is a diagram for explaining an example of a table in the database in hydroponics of this embodiment. FIG. 9 is a flowchart for explaining an example of controlling the supply of water based on the database shown in FIG.
The table shown in FIG. 8 is the simplest example in hydroponics. For example, the database is the ID of the plant name,
It is composed of a table that shows the relationship between the diameter of the stem or stem diameter during the growth process and the hydroponic solution for the stem or stem diameter. That is, the diameter of the stem or stem diameter is divided into, for example, three ranks by the computer 44 after the analog amount from the in-plant water content measuring sensor 42 is converted into digital. In addition, in the table, the opening degree of the valve with respect to the rank of the diameter of the stem or the stem diameter is predetermined.

The computer 44 changes the output of the relay output circuit 51 based on the table shown in FIG. 8 to fully open the first valve 68 for supplying the hydroponic liquid 63.
It will be half open or closed. Next, an example of draining in hydroponics will be described based on the flowchart shown in FIG. The computer 44 checks whether or not the diameter of the stem or stem diameter exceeds "1" based on the information from the in-plant water content measuring sensor 42 and the information in the table (step 91). When the computer 44 determines that the diameter of the trunk or stem diameter does not exceed "1", the computer 44 sends a signal to the relay output circuit 51 so as to fully open the first valve 68 and close the second valve 69 ( Step 9
2).

When the computer 44 determines that the diameter of the stem or stem diameter exceeds "1", it checks whether or not the diameter of the stem or stem diameter has reached "2" (step 9).
3). When the computer 44 determines that the diameter of the trunk or the stem diameter has not reached “2”, the first valve 68
Is fully opened and a signal is sent to the relay output circuit 51 so as to close the second valve 69 (step 94). When the computer 44 determines that the diameter of the trunk or stem diameter has reached “2”, the computer 44 opens the first valve 68 and the second valve 69 halfway. That is, when the pressure of the hydroponic solution 63 supplied from the pump 67 is constant, part of the hydroponic solution 63 is returned to the original hydroponic solution tank 66 via the second valve 69 ( Step 95). The computer 44 checks whether or not the thickness of the trunk or stem diameter has reached "3" (step 96).

If the computer 44 determines that the diameter of the stem or stem diameter has not reached "3", the first valve 6
8 and the second valve 69 are left half open (step 97). When the computer 44 determines that the diameter of the trunk or stem diameter has reached “3”, the computer 44 closes the first valve 68 and fully opens the second valve 69 (step 98). That is, the plant will start draining. Next, the computer 44 checks whether or not the diameter of the trunk or stem diameter reaches "2" after closing the first valve 68 once (step 99). In other words, it is investigated whether or not the plant becomes withered after being drained.
When the computer 44 determines that the diameter of the trunk or stem diameter has not reached “2” after the first valve 68 has been closed once, the computer 44 leaves the first valve 68 and the second valve 69 in the above steps. , Keep the plant drained (step 100).

When the computer 44 determines that the diameter of the stem or stem diameter reaches "2" after the first valve 68 is closed once, the first valve 68 and the second valve 69.
Is half-opened to supply a hydroponic solution to prevent the plant from dying (step 101). The computer 44 returns to step 96, checks whether or not the water content in the plant has been restored, and repeats the same processing as described above. In the above-described embodiment, the environment for cultivating plants has been simplified most. However, the actual table not only differs depending on the type of plant, but also undergoes complicated steps. Although the database of the above embodiment is stored in the form of a table, the data can be stored in the form of a code.
