DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS The wireless labor management system of the present invention will be described below in more detail with reference to the embodiments shown in FIGS.

FIG. 1 is a block diagram of the entire system in a work site. Three base stations 2a, 2b, and 2c are provided at intervals of 100 m in the work site.
In particular, the base station 2a is provided in the vicinity of the entrance / exit 1, has a lower receiving sensitivity than other base stations, and has two antennas 9 for diversity reception. This is the portable wireless telephone terminal 4 near the entrance 1
This is for more accurately measuring the electric field strength of the first embodiment. Entrance 1
Is provided with a gate 1a that opens and closes electrically.

The base station 2 has a PHS (PERSONAL H).

Hereinafter, a specific operation will be described with reference to FIG. This flowchart assumes that a person carrying a portable wireless telephone terminal 4 having a regular ID passes through the entrance 1. When the portable radio telephone terminal 4 approaches the entrance / exit 1 (base station 2a), the portable radio telephone terminal 4 moves to the base station 2a.
And transmits its own ID information. Here, the base station 2a receives the ID information of the portable radio telephone terminal 4 and sends it to the host computer 3.

The host computer 3 analyzes the ID,
The ID stored in the storage unit 6 is compared with the holder name file. When it is confirmed that the person is a legitimate registrant, the gate 1a is opened and the person is allowed to pass. At this time, the base station 2a
Although the electric field strength of the portable radio telephone terminal 4 fluctuates,
The direction of the change can be detected for diversity reception.
