A monitoring system for a working machine includes: a position detector to determine a position of a working machine based on radio waves from positioning satellite(s); an area setter to set work area information indicating whether work area(s) is/are in a shielded environment or an unshielded environment, the work area(s) being area(s) where work is to be done by the working machine, the shielded environment being an environment in which the radio waves are likely to be blocked, the unshielded environment being an environment in which the radio waves are unlikely to be blocked; and a monitor to evaluate a state of position determination by the position detector based on a result of the position determination by the position detector, and provide a notification if there is a predetermined change in the state of the position determination compared to a state of position determination corresponding to the work area information.

Monitoring system for working machine

A working machine includes a traveling vehicle that is a first moving entity, a working device that is a second moving entity coupled to the first moving entity, and a sub battery loaded on the second moving entity to store an energy source to drive the traveling vehicle. Therefore, it is not necessary to newly provide a configuration to load the sub battery on the traveling vehicle, and a battery can be easily loaded. In a case where the traveling vehicle includes a main battery, the traveling and work can be continued according to a capacity of the sub battery without being stopped in order to charge the main battery that has a decreased remaining charge level.

A communication processing system for a working machine includes a communication device disposed on the working machine and configured to transmit a beacon containing machine information relating to the working machine, and a mobile terminal configured to receive the beacon, and to execute a connection processing for connecting with the communication device and an obtaining processing for obtaining the machine information, wherein the beacon includes a first beacon containing first activation information and a second beacon containing second activation information, and wherein the mobile terminal is configured, after executing the connection processing and the obtaining processing upon receiving the first beacon, not to execute the obtaining processing upon further receiving the first beacon, and to execute the same obtaining processing upon receiving the second beacon.

Communication processing system for working machine and communication processing method for working machine

A communication system for a working machine includes a communication device disposed on the working machine, and a mobile terminal to be connected to the communication device. The communication device transmits a service universal unique identifier (UUID) to the mobile terminal. The mobile terminal transmits unique information to the communication device. The communication device issues connection request to the mobile terminal after receiving the unique information. The mobile terminal requests transmission of authentication information after issuing the connection request, the authentication information being used for paring. The communication device transmits the authentication information to the mobile terminal in response to the request. And, the mobile terminal judges whether the paring is established based on the authentication information, and executes a program based on the service universal unique identifier (UUID) when the paring is established.
