Abstract
The present invention comprises: a wearable sensor that is worn by a worker, the wearable sensor having a sensor that receives sensor data from a sensing object, and a transmitter that transmits to a terminal the sensor data received by the sensor; and a computer that determines operation content for the worker on the basis of the sensor data received from the wearable sensor, and outputs the result of the determination to a display unit.
Claims6
A work information management system comprising:
- a glove-shaped wearable sensor including a plurality of pressure sensors for each finger portion of the glove-shaped wearable sensor individually receive sensor data from a sensing object;
- a transmitter;
- and
- a computer wirelessly coupled to the transmitter and coupled to a display,
- wherein the transmitter wirelessly transmits the sensor data of each pressure sensor to the computer,
- wherein the computer is configured to:
- receive and store respective first sensor data of each of the pressure sensors as a result of a first worker gripping the sensing object,
- receive and store respective second sensor data of each of the pressure sensors as a result of a second worker gripping the sensing object,
- compare the first sensor data and the second sensor data for each pressure sensor respectively and determine whether there is a deviation greater than a predetermined value, and
- upon determining there is a deviation greater than the predetermined value display, on the display, information indicating a correction of the grip of the second worker of gripping the sensing object,
- wherein the wearable sensor receives, from the sensing object, the sensor data obtained by touching a concave-convex shape of a sensing assistance attached to the sensing object,
- wherein the wearable sensor receives the sensor data from the sensing object by tracing the concave-convex shape of the sensing assistance, and
- wherein computer identifies the sensing object based on a sensor value obtained by touching the concave-convex shape included in the sensor data.
