Abstract
A monitoring region for monitoring entry of an obstacle is set around a machine main body. A plurality of obstacle sensing sensors sense an obstacle in the monitoring region and sense an obstacle in different directions with respect to the machine main body. A construction machine accumulatively stores approach information indicating that an obstacle has been sensed by any of the plurality of obstacle sensing sensors in a specific period, and outputs the approach information to be displayed on a display device.
Claims14
An obstacle monitoring system comprising:
- one or a plurality of construction machines;
- a server;
- and
- an information processing device,
- the construction machines, the server, and the information processing device being connected via a network,
- wherein each of the construction machines includes:
- a machine main body;
- a monitoring region setting unit which sets a monitoring region around the machine main body, the monitoring region being for monitoring entry of an obstacle;
- a plurality of obstacle sensing sensors arranged in the machine main body for sensing an obstacle entering the monitoring region from different directions;
- a storage unit;
- a storage processing unit which generates, when the obstacle has been sensed by at least one of the plurality of obstacle sensing sensors in a specific period, approach information indicating that the obstacle has been sensed to cause the storage unit to accumulatively store the approach information;
- and
- an output processing unit which outputs the approach information accumulatively stored in the storage unit in the specific period,
- wherein the server includes a log data storage unit which stores the approach information output from each of the construction machines, and
- wherein the information processing device includes:
- a communication unit which obtains the approach information from the server;
- and
- a control unit which displays the obtained approach information on a display.
