The present invention appropriately manages a battery by driving a sensor by using the power of the battery, and by transmitting the results of measurement by the sensor by data communication using wireless communication. Detection devices that operate on battery power are retained at moving parts of an operation machine; posture information of the moving parts is detected by sensors provided to the detection devices and is transmitted from the detection devices by data communication using wireless communication; assistance information for assisting operations by an operator is generated on the basis of the posture information transmitted from the detection devices and is notified to the operator; remaining battery power information is acquired by the detection devices; and on the basis of the remaining battery power information and an operation plan of the operation machine, battery replacement timing is projected and is notified to the operator of the operation machine.
