1. A device-condition information collecting method for collecting device-condition information of each of a number of devices to be managed, comprising:
performing, by a portable unit including a sensor for device-condition detection, a detecting operation on each managed device of a direct collection group having at least one managed device; collecting, by the portable unit for device-condition detection, device-condition information of each managed device of the direct collection group having at least one managed device; performing, by a stationary unit including at least one sensor for device-condition detection, a detecting operation on each managed device of an indirect collection group having at least one managed device; and collecting, by the stationary unit, device-condition information of each managed device of the indirect collection group having at least one managed device, wherein the stationary unit is disposed to be capable of detecting the device-condition information of each managed device for the device-condition detection, wherein each of the number of devices to be managed is associated with a frequency of collecting the device-condition information in accordance with at least one of a situation and an actual current condition thereof, the method further comprising: collecting, by the portable unit, the device-condition information of all or some of the managed devices having a same collection frequency as the managed devices of the direct collection group; and collecting, by the stationary unit, the device-condition information of the managed devices not in the direct collection group as the managed devices of the indirect collection group. |
