Abstract:
The purpose of the present invention is to provide a work management system capable of efficiently extracting an approach event having a high probability of contact between a work machine and a worker. For this purpose, a management server is configured to: determine whether there is an approach between a work machine and a worker on the basis of positional information of the work machine measured by a work machine position measurement device and positional information of the worker measured by a worker position measurement device; in response to determining that there is an approach, determines, on the basis of a preset approach state definition, the approach state of the approach from the state of the work machine measured by a work machine state measurement device at the time of the determination of the approach; and records the state of the work machine measured at the time of the determination of the approach in association with the approach state, and outputs the state of the work machine to a display device in association with the approach state.
