Modes for carrying out the present invention will be described in detail with reference to the drawings.

FIG. 1 is a diagram showing a system for managing operation information of grain dryers.

The grain dryer of the present embodiment is a known one provided with a moisture meter (not shown) for measuring the moisture content of sample grains and a controller for controlling the drying operation.

Off-line controllers (not shown) are provided for control units of grain dryers 1, 2, and 3 installed in parallel in a rice center or a large building. A management mobile terminal T such as a tablet and a plurality of grain dryers 1, 2 and 3 are configured to be able to communicate with each other by short-range wireless communication such as BLEUTOOTH.

In this wireless communication, the grain dryers 1, 2, 3 and the management terminal T can communicate with each other within a distance of about 10 m. , are placed in the vicinity of the grain dryers 1, 2, 3. After the drying operation of all the grain dryers 1, 2, and 3 is completed, the operator can appropriately carry it and use it for viewing and managing the operation history.

The operator described in this embodiment refers to the owner or manager of the grain dryer, the operator of the drying operation, and the like.

Communication between the grain dryers 1, 2, and 3 and the management terminal T starts when the grain dryer 1 and the management terminal T are connected and the operation information of the grain dryer 1 is input to the management terminal T. , the communication with the grain dryer 1 is cut off, then the grain dryer 2 and the management portable terminal T are connected, and the operation information is similarly input. After that, connection and disconnection of communication are performed in the order of the grain dryer 3 and the grain dryer 1 . That is, the grain dryers are sequentially connected and disconnected with the portable management terminal T one by one.

The mobile management terminal T side is configured to sequentially select the control units (not shown) of the grain dryers 1, 2, and 3 to be connected, and by collecting the operation information data of each grain dryer, Only a small amount of data is received at one time, the communication load is small, and reliable communication is possible.

For example, if the operation information is set to be input to the management mobile terminal T every minute, when 10 grain dryers and the management mobile terminal T are connected, one grain dryer The configuration is such that the management mobile terminal T receives the driving information every 10 minutes.

In addition, the interval at which data on the operation information of one grain dryer is received is configured to be shorter as the number of connected grain dryers is smaller. That is, for example, in the case of five grain dryers, the mobile management terminal T receives data for one grain dryer every five minutes. With this configuration, when the number of owned grain dryers is small, detailed operation data can be acquired accordingly.

A part of the operation information of a plurality of grain dryers input to the management portable terminal T is sent by e-mail to the portable terminal S such as a mobile phone owned by the operator via the Internet wireless communication M. .

As for the operation information to be transmitted, the minimum necessary drying operation information (current moisture value, expected time of completion of drying operation, etc.) to know the drying state as shown in FIG. 13 is periodically transmitted. "Regularly" means every set time (for example, every hour), and the operator can grasp the operating state of the grain dryer while harvesting with a combine harvester at a location away from the grain dryer, for example, in a field. In FIG. 13, the operation information of a plurality of grain dryers is sent simultaneously, so that the operator can grasp the operation information of the plurality of grain dryers at the same time, and the number of mail transmissions during the entire drying operation is reduced. Therefore, it is possible to reduce the amount of communication required for sending an e-mail.

The information sent by e-mail includes, as shown in FIG. When the operation for each work process is completed, such as the completion of the discharge operation after the drying operation, it is also possible to send an e-mail to that effect.

The mail can be sent to the portable terminals S1 and S2 possessed by a plurality of persons, respectively, and the contents of transmission can be changed for each of the portable terminals S1 and S2.

As shown in FIG. 16, for example, the operating status of the drying operation is transmitted to the handheld mobile terminal S1, and the abnormality information or the operation end information is transmitted to the handheld mobile terminal S2. In this case, for example, the handheld mobile terminal S1 is suitable for transmitting data to a person who wants to grasp the progress of the drying operation, such as the manager of the overall harvesting/drying work, and the handheld mobile terminal S2 is suitable for sending data to a farm field or grain drying. Suitable for on-site workers who move between buildings with machines. In this way, by enabling setting of transmission contents, it is possible to reduce the amount of transmission data and the communication fee.

It should be noted that the abnormality information may be sent by e-mail prior to other driving information. For example, other driving information is sent by e-mail every set time (one hour), and anomaly information is sent by e-mail at any time when the anomaly information is input to the management portable terminal. This enables the operator to quickly respond to the abnormal information.

In addition, as shown in FIG. 17, it is also possible to transmit detailed information on the drying operation such as the state of water content variation, and to set the time interval for the timing of mail transmission.

When all the drying operations are completed, the management portable terminal T stores the history data of the operation information of the grain dryer so far, and the manager operates the management portable terminal T appropriately to The data of the operation information can be used for daily work reports, future harvesting/drying operation plans, and the like. In addition, the wireless communication of the Internet only requires transmission of part of the driving information by e-mail, so that the configuration can be made inexpensive.

The embodiment of FIG. 1 is a simple drying operation management system using a management mobile terminal T and a possessed mobile terminal S. FIG.

Next, a second management system in which drying operation information can be accumulated by the data management server D and managed by the manager's personal computer P will be described with reference to FIG.

Drying operation information input to and stored in the management portable terminal T is transmitted from the management portable terminal T to the data management server D via Internet wireless communication M, and the operation information and operation history are accumulated. The data management server D stores the operational information obtained not only from grain dryers but also from tractors and combine harvesters. It is possible to centralize the information management of agricultural work.

The operator can arbitrarily select either the management system based on FIG. 1 which does not use the data management server D or the second management system based on FIG. 2 which uses the data management server D. is. Although not described in detail, any one of them can be selected by a touch switch on the screen of the mobile terminal T for management. As a result, the owner or manager can arbitrarily choose whether to use a low-cost management system or a second management system that can centrally manage not only grain dryers, but also tractor and combine operation information. It is possible.

The driving information that is input to and displayed on the management portable terminal will be described below.

FIG. 3 is a diagram showing operation information during drying operation.

Dryer No. displayed on the screen G of the portable terminal for management. 1 to NO. 5 shows the operating status of five grain dryers. Main operation information in the drying operation, such as the producer, grain moisture condition, drying completion time, etc., is displayed. Then, the display content is automatically updated at set time intervals (for example, at intervals of one minute) for each grain dryer. Various switches (setting screen changeover switch, fuel usage amount screen changeover switch, etc.) are provided below the table, and the screen G is switched according to the content of the switch.

In FIG. 3, as shown in FIG. 4, it may be possible to set or switch to a screen for displaying the charging operation information, the discharging operation information, the drying operation mode, and the like.

The fuel consumption column in FIG. 4 is a predicted value calculated based on the predicted end time during the drying operation.

FIG. 5 shows the accumulated operation time for each work process of the grain dryer. For example, the cumulative operating time used from the time of purchase, such as 828 hours of cumulative drying operation time and 129.4 hours of pre-loading time, is counted and displayed to indicate the timing of maintenance.

Then, if there is a work process in which the accumulated time has passed the set time, that effect is displayed as maintenance information or the like. Details such as maintenance information are switched to a detailed screen as shown in FIG. 6 by operating the switch for the item.

FIG. 6 shows the inspection/cleaning time of each part of the device and the actual operating time. The inspection time of 100 hours is a setting that maintenance such as inspection and cleaning is required every 100 hours. When the operating time exceeds 100 hours, the operating time is colored, and inspection and cleaning are requested.

"Reset" in the "Confirmation" column means that when the operator operates the "Reset" switch, it is assumed that the inspection/cleaning is finished, the operating time is reset, and the operating time is counted again.

This operating time is a measurement time for measuring the timing of inspection and cleaning, and is different from the cumulative time of all the drying operations that have been performed so far.

FIG. 7 displays the drying operation history (performance) of the grain dryer so far within the set period. In this embodiment, it is possible to set and display the display period of the driving history.

FIG. 8 selects a specific drying operation and displays the accumulated operation time for each work process (charging, ventilation, drying, discharging) of the drying operation in a bar graph. As another screen of FIG. 8, the accumulated operation time for each work process of a plurality of drying operations may be displayed as shown in FIG. 9, or the actual operation time may be displayed as shown in FIG. In particular, according to the display of FIG. 10, it is possible to easily see which work process was performed at which time, and it is possible for the manager to easily judge whether the drying operation was appropriate.

FIG. 11 is a diagram showing changes in the distribution of sample grain moisture values measured by a moisture meter (not shown) during drying operation. Moisture distribution is shown. In FIG. 11, the moisture values measured at 18:00, 19:00, and 20:00 are displayed, but it is possible to switch to the screen of the moisture distribution graph measured before (for example, 17:00). When the previous time of 17:00 is displayed, the screen displays moisture distribution data for three times, 19:00, 18:00, and 17:00.

FIG. 12 shows the fuel (kerosene) consumption for the designated grain dryers. In this embodiment, the fuel consumption amount for each dry operation day and the accumulated fuel consumption amount for the year are shown. This makes it easier for managers to calculate expenses. Also, in FIG. 12, the grain type can be designated from among the grains dried by the grain dryer, and the amount of fuel used for burning the grain can be displayed. In FIG. 12, all grains (rice, barley, buckwheat, and beans) are selected, but it is also possible to select a specific grain type (for example, only beans) and display the fuel consumption. Thereby, it is possible to manage the fuel consumption for each type of grain.

FIG. 18 is a screen showing a history of drying operation information after the drying operation ends. This screen has columns for the weight of unpolished rice and the weight of scrap rice. This field is provided so that the operator can manually input data after the hulling work at a later date, so that management after the harvesting period can be performed.
