Next, the operation of the above configuration will be described.
In FIG. 1, among the plurality of water level adjustment devices 6 installed on the drain groove 7 side, for example, three of the water level adjustment devices 61 to 63.
A description will be given of an example in which the height of each gate is changed from the current set height for the stand. In this case, the operator inputs a calling code number from the input device 22 on the wireless control device 1 with respect to the target water level adjusting device, for example, in the order of the water level adjusting devices 61 to 63. Then, in accordance with the input order, the wireless control device 1 (that is, the internal outward wireless communication device) transmits a control signal, and firstly, the water level adjusting device 6
Call 1 When the water level adjusting device 61 is called,
The backward wireless communication device 14 of the water level adjustment device 61 returns the “current water gate height set value data” adjusted by the water level adjustment device 61 to the outward wireless communication device of the wireless control device 1. I do.

The operator checks the "current data of the water gate height set value" displayed on the display device 21 (for example, liquid crystal display means) provided in the wireless control device 1. Then, when the operator inputs “data of the sluice gate height set value to be changed” as necessary according to the result of the confirmation from the input device 22, the outgoing wireless communication device of the wireless control device 1 sets the “slope height to be changed” Data of the set value "
Is transmitted again as a control signal, and an operation of changing and adjusting the water level of the paddy field is performed. Therefore, there are two control signals, a call signal and a change setting signal.

The water level adjusting device 61 controls the water gate height by using the electric drive device 9 based on the received “data of the water gate height set value to be changed”. The directional wireless communication device 14 returns “the data of the controlled floodgate height” to the outward wireless communication device of the wireless control device 1 again. Note that “data of the current gate height setting value”, “data of the planned gate height setting value” and “data of the controlled gate height” are, for example, “floor water level measurement” "Data" is also possible.

When the operator can confirm on the display device 21 that the re-reply content is the same as the transmitted change command, the operator adjusts the water level of the paddy field 5 controlled by the water level adjustment device 61. Perform the operation of ending. For example, an “end signal” is input from the input device 22. Or
If there is no operation by the operator during a certain period of time, the wireless control device 1 automatically determines that the water level adjustment operation has ended. Subsequently, the wireless control device 1 automatically calls the next water level adjustment device 62 in accordance with the order of the call code numbers already input. Then, in a similar procedure, the height of the water gate of the water level adjusting device 62, that is, the water level of the paddy field adjusted by the next water level adjusting device 62 can be controlled. The water level adjustment device 63 can similarly execute the control for changing the paddy water level.

The above is summarized as follows. The feature of the paddy water level adjustment device according to the present invention is composed of a plurality of water level adjustment devices having the function of a lock and one wireless control device, and the wireless control device uses digitally modulated radio waves of the same frequency, It has a function of calling any one of a plurality of water level adjusting devices having different call code numbers and remotely controlling the same. According to this, it is possible to remotely control a plurality of water level adjustment devices individually with one wireless control device, and to easily and efficiently perform a complicated operation of adjusting a water level in each of a plurality of fields. It becomes possible. In other words, there is provided a paddy water level adjusting device with improved convenience of operation in which a single wireless control device can arbitrarily select and remotely control a plurality of water level adjusting devices installed in a plurality of paddy fields.

Another aspect of the paddy water level adjusting device according to the present invention is that the radio control device and the water level adjusting device are capable of transmitting and receiving digitally modulated radio waves of the same frequency. (Forward / backward wireless communication device)
It has a place. According to this, for example, in response to an inquiry from the forward direction wireless communication device of the wireless control device, a reply about the current gate height is performed from the backward direction wireless communication device of the water level adjustment device, and in response to this, It is possible to exchange data in an interactive manner (exchanging instructions and repetition), such as giving an instruction to change the water gate height from the control device, and it is possible to grasp the current water level adjustment state of the paddy water level adjustment device, It is possible to increase the reliability of the adjustment control. In other words, a paddy water level adjustment device that is easy to handle and has a two-way communication system in which water level information can be exchanged between the wireless control device and the water level adjustment device in an interactive manner is provided.

Further, according to another aspect of the characteristic of the paddy water level adjusting device according to the present invention, the radio control device includes:
When all of the calling code numbers of the plurality of water level adjustment devices that have been operated are input prior to executing the water level adjustment control, this is stored, and the water level adjustment device to be controlled is sequentially called, and necessary. It has a function of controlling the water level adjusting device accordingly. According to this, when it is necessary to control a plurality of water level adjustment devices, to input all the call code numbers prior to the control, it is possible to prevent erroneously controlling a water level adjustment device that is not targeted, Control operations can be facilitated.
That is, when operating a plurality of water level adjustment devices installed in a plurality of fields, the call code numbers of all the water level adjustment devices to be operated are input to one wireless control device in advance, so that the input can be performed. A paddy water level adjustment device with improved convenience, in which the target water level adjustment devices are sequentially called in accordance with the order and the respective water level adjustment controls can be reliably performed, is provided. In the above embodiment, the water level adjusting device controls the water level of the paddy field by using a water gate (that is, a water stop plate). However, a water stop valve or the like may be used instead of the water stop plate.

Returning to FIG. 3, the electric drive 9
Operates using the solar cell 8 as a power source, but if the built-in backward wireless communication device 14 is always in a standby state in which it can respond to a call from the wireless control device 1, a considerable amount of power is consumed. This causes the solar cell 8 and the storage battery 17 to become larger, which in turn leads to an increase in the price of the entire device. In order to improve this, the backward wireless communication device as one component of the water level adjustment device is provided with a standby state in which the control signal from the wireless control device can always be received and a pause state in which the control signal cannot be received. And intermittent standby means (functional characteristics) of repeating periodically and alternately.

For example, if a pause is taken for 40 seconds after waiting for 20 seconds, the power consumption in the case of always waiting is reduced.
0/60, that is, it can be reduced to one third. The longer this pause time is, the lower the power consumption is, but on the other hand, it causes the inconvenience of increasing the chances of not being able to immediately respond to a call from the wireless control device 1. That is, if the call has just entered the pause time zone, the wireless control device 1 must wait until the next standby state starts, and the longer the pause time is set, the more inconvenient it becomes. From a practical point of view, when the allowable value of the pause time was actually measured, the result was obtained that it was desirable to be within 30 seconds at most, that is, in the range of 40 (seconds) ≥ pause time ≥ 20 (seconds). . By setting the pause time in this way, there is no problem in practical use, the power consumption of the solar cell 8 and the storage battery 17 can be suppressed, and the size can be prevented.

That is, the paddy water level adjusting device includes a storage battery and a solar cell for charging as a power source of an electric drive device of the water gate, and the electric drive device is in a standby state in which a signal from the wireless control device can be constantly received. And a pause state in which the power is turned off is alternately and periodically repeated for a certain period of time. According to this, since it is possible to reduce power consumption without practically lowering the reception capability of the electric drive device, the capacities of the storage battery and the solar cell are suppressed, and the price of the device is reduced. To make things possible.

That is, another feature of the paddy water level adjusting apparatus according to the present invention is that, in order to suppress consumption of the electric power stored in the storage battery, the paddy water level adjusting apparatus always responds to an operation signal from the wireless control apparatus. In addition to the standby state, the electric drive of the water gate in the standby state has a function of taking a rest state in which the power supply is turned off, and these states are alternately and periodically repeated for a certain period of time. To reduce power consumption during the sleep state. In other words, another feature of the paddy water level adjusting device according to the present invention resides in that it has intermittent standby means. An electric drive device for the floodgate is provided with such a characteristic that a standby state and a pause state are periodically and continuously repeated, thereby suppressing power consumption and providing an inexpensive paddy water level adjusting device.

On the other hand, if there are a plurality of water level adjusting devices to be subjected to the water gate height change, if the intermittent standby means is provided, every time one of the water gates is changed and the next call is made, the apparatus enters the above-mentioned rest period. In this case, there is a possibility that the operator may become irritated or disgust during the waiting time that occurs each time. As a solution to this, the backward wireless communication device 14
Once a "call" as a predetermined signal from the wireless control device 1 is received, the standby state is continuously maintained for a certain period of time. During this time, the intermittent standby control is temporarily released, and the floodgate operation is performed without a standby time due to a pause. It is effective to add a function that can perform

That is, the electric drive unit has a function of suspending the function of keeping the intermittent standby control in a halt state for a certain period of time only when receiving a call signal from the radio control apparatus, and setting a function of always making a standby state. Have. According to this, the halt state provided from the viewpoint of reducing power consumption prevents the risk of increasing the waiting time when operating the paddy water level adjustment device and complicating the operation. A good paddy water level adjusting device can be provided.

That is, another feature of the rice paddy water level adjusting device according to the present invention is that the paddy water level adjusting device having the above-mentioned idle state function has a function of changing the height of the floodgate. When called by the wireless control device, the sleep state function is stopped for a certain period of time, and the operation of changing the water gate height can be performed smoothly without waiting time due to the sleep state. In other words, another feature of the paddy water level adjusting device according to the present invention is to provide a means for canceling the intermittent standby.

Further, a method of canceling the intermittent standby is adopted. A method of first calling all of the plurality of target machines prior to the operation is conceivable.
Of course, the waiting time may exist for each call, but since the call is terminated at an initial stage prior to the operation of changing the gate height, the subsequent operations are performed without any waiting time. Therefore, the irritability of the operator can be eliminated.

The length of the stand-by state (the length of the release time) that is maintained for a certain period of time is determined in consideration of the number of paddy water level adjustment devices to be operated simultaneously and the time required for each operation. Can be determined. The practical length of release time for a plurality of water level adjustment devices that are practical to be controlled by one wireless control device (ie, 10 ± 2) is about 10 minutes (ie, 10 minutes ± 2 minutes). Is appropriate.

That is, still another feature of the paddy water level adjusting device according to the present invention is that when there are a plurality of paddy water level adjusting devices to be operated for changing the gate height, and all of them are selected on the radio control device. Each time the same device is called, the above-mentioned sleep state function of each device is stopped for a certain period of time, and the operation of changing the gate height can be performed smoothly without waiting time due to the sleep state. In other words, a water gate electric drive device having a characteristic of periodically repeating the standby state and the halt state is continuously provided for a certain period of time when the water gate operation is required. As a result, a paddy water level adjusting device with improved operational convenience is provided.
