[0022]

BRIEF DESCRIPTION OF THE DRAWINGS In order to further elaborate the invention, a preferred embodiment is described below with the associated flow chart.

Embodiment 1 The structure of the downlink signal of the air interface is shown below.

[0024]

[Table 1]

Here, P represents a prefix code which is a continuous 32-bit code encoded according to the data protocol encoding, and S is a synchronization code, which has 2 bytes for synchronization of a decoding program. . If necessary, the synchronization code can be sent twice consecutively (32 bits in total), but the whole system must adopt the same format. C is a check code having 2 bits, for example, 00 and 1
1 is an unused code, 01 represents CID, and 10
Represents GID. SID (14 bits in total), CID and G
The ID (16 bits in total) is defined as described above.
CID and GID are determined according to C, and 01 of C is CI
Assigned to represent D, 10 in C is assigned to represent GID. D / C is data or a command, and the number of bits is determined as needed.

The monitoring method is built in the EEPROM.

[0027]

[Table 2]

In the above table, SID, C, CID / GID
Conforms to the definition of the air interface, and employs an 8-bit sort ID. That is, the number of patients in each patient group does not exceed 256. Of course, the sort ID can be longer than 8 bits to accommodate a specific situation where the number of patients in each patient group exceeds 256. However, if the sort ID is too long, the signal transmission efficiency is reduced.

The case where the patient's GID and sort ID are as shown in Table 3 below is shown below. All numbers in the table are 1
It is a hexadecimal number. The top row is the GID and the bottom row is the total number of patients in the group. The leftmost column is C for each patient.
ID. The other numbers in the table represent the sort ID in the GID shown in the top row for the patient with the CID shown in the leftmost column.

[0030]

[Table 3]

According to Table 3, the patient 0000 (hereinafter, CID represents the patient name) has a GID of 0000,000.
1,0002,0004. If the air interface group call is 0000 or 0002, patient 0000 replies to the first time (delay time is 256 ms × 0). If the air interface group call is 0001, patient 0000
Replies at the third time (delay time is 256ms
× 2). If the group call of the air interface is 0004, the patient 0000 returns at the 26th time (16 × 1 + 10 = 26) (delay time is 2
56 ms × 25).

Similarly, when a group call is made to the GID0003 air interface, only eight patients in the group receive the signal. In situations where a reply is required, the eight patients in the group would be the first, second, third, fourth, fifth, sixth, seventh, and At the eighth time (that is, 0 ms, 256 ms, 51 ms, respectively)
2ms, 1024ms, 2048ms, 4096ms,
CID 0003 → 0008 → 0006 → 000B, with delay times of 8192 ms and 16384 ms)
Reply is automatically made in the order of → 000E → 000D → 0011 → 08AF.

If the single call of the air interface is CID000A, only the patient will receive the signal. If a reply is required, the reply is made at the first time (the delay time is 0 ms).

The above method for determining a group call reads the check code C (C = 01 for single call (CID) and C = 10 for group call (GID)) in the received signal. It is performed by using software.

The above delay time can be achieved by using a software loop (FOR... NEXT). When the delay time has elapsed, the monitoring system sends an automatic reply by H / L driving.

The above method is shown in FIG. First, the terminal monitoring system checks the data (SID, check I) in the SRAM.
DC, CID, sort ID corresponding to GID, etc.) (step 101), and enters a standby state (step 1).
02). After receiving the signal (step 103), the end monitoring system identifies the SID (step 104) and
If D does not match, a standby state is entered. If they match, the end monitoring system identifies the GID (step 1).
05). If the GIDs match, the end monitoring system identifies the reply ID (step 106). If it is confirmed by the identification of the reply ID that a reply is necessary, the terminal monitoring system calculates the delay time (step 108) and counts the delay time (step 11).
0), and after the elapse of the delay time, a signal is transmitted (step 111). If it is confirmed by the identification of the reply ID that no reply is necessary, the terminal monitoring system returns to the standby state. When the signal has been transmitted, the terminal monitoring system returns to the standby state. If the GIDs do not match, the end point monitoring system identifies the CID (step 1).
07). If the CIDs do not match, the process returns to the standby state. If they match, the terminal monitoring system identifies the reply ID (step 109). If it is confirmed by the identification of the reply ID that a reply is necessary, the terminal monitoring system sends a signal (step 111). If it is confirmed by the identification of the reply ID that no reply is necessary, the terminal monitoring system returns to the standby state. When the signal has been transmitted, the terminal monitoring system returns to the standby state.

The delay time DT is calculated according to the following equation. DT = 256 msec (n _OD -1) In the above equation, n _OD indicates the value of the sort ID shown in Table 3. The delay time is determined by software means, for example, FOR-N
It is counted using an EXT loop.

FIG. 4 shows a method similar to the method shown in FIG. The difference between these methods is that the method shown in FIG.
ID is identified first (step 105), and then CI
While D is identified (step 107), the method shown in FIG. 4 first checks the CID (step 2).
05), the GID is checked thereafter (step 207).
