[First Embodiment]
FIG. 1 shows a schematic diagram of a grain management system.
The grain management system is a system for managing agricultural crops. Hereinafter, for convenience of explanation, the description will be made assuming that the crop is a grain such as rice or wheat. As a matter of course, crops are not limited to rice and wheat.

As shown in FIG. 1, the grain management system includes a first communication device 10. The 1st communication apparatus 10 outputs the information (container information) regarding the container 11 which accommodates grain to the outside with the beacon which is a broadcast signal. The container 11 is a flexible container bag (flexible container), a container, or the like. The container information includes size (vertical, horizontal, capacity) information or identification information for identifying the container 11 (specific information for identifying the container 11). In this embodiment, the container information is identification information for identifying the container 11. The identification information is a unique number (management number) individually assigned to each container 11. The identification information may be anything as long as the container 11 can be specified, and is not limited to that described above. Hereinafter, for convenience of explanation, the description will proceed assuming that the container information is identification information.

  The first communication device 10 is provided in the container 11. As shown in FIG. 3, the 1st communication apparatus 10 is provided in the vicinity of the opening part 11a which puts a grain, for example. Specifically, when the container 11 is a rectangular container, the first communication device 10 is attached to the inner surface of the upper part (opening 11 side) of the peripheral wall 11b that forms the opening 11a. In addition, the 1st communication apparatus 10 may be attached to the outer surface of the upper part of the surrounding wall 11b of a container, and may be attached to the other location.

As illustrated in FIG. 2, the first communication device 10 includes a storage unit 10a, a power supply unit 10b, and an output unit (hereinafter referred to as a first output unit) 10c. The storage unit 10a is composed of, for example, a nonvolatile memory and stores identification information.

The first output unit 10c is a communication module that outputs a beacon, and outputs a beacon indicating identification information stored in the storage unit 10a to the outside at a predetermined interval, for example, every few seconds. The distance (output distance) of the beacon output from the first output unit 10c is set to several centimeters to several tens of centimeters, for example.

  The first communication device 10 may include an inertial force detection unit 10d. The inertial force detection unit 10d is an acceleration sensor or the like. The inertial force detection unit 10d and the first output unit 10c are connected, and the first output unit 10c is operated by a signal from the inertial force detection unit 10d. For example, when the acceleration sensor continuously detects the vibration of the container 11 for a predetermined time (for example, several seconds to several tens of seconds) or more, the first output unit 10c determines that the grain is put in the container 11 and the beacon. Is output. After the beacon is output, the first output unit 10c continues to output the beacon while the container 11 continues to vibrate.

  On the other hand, for example, when the vibration of the container 11 is continuously stopped for a predetermined time (for example, several seconds to several tens of seconds), the first output unit 10c stops outputting the beacon assuming that the operation of the container 11 is stopped. To do. Therefore, when the inertial force detection unit 10d is provided in the first communication device 10, since the beacon can be output to the outside only in the state where the grain is put in the container 11, the power supply in the power supply unit 10b Consumption can be suppressed.

As shown in FIGS. 1 and 2, the grain management system includes a first receiving device 12. The first receiver 12 is provided in a processing facility 18 such as a rice center that processes grain.
