The data is temporarily stored in the memory 8 'of the CPU 8, and the CPU 8 sends the stored data to the personal computer 6 together with the ID number when the interface with the personal computer 6 becomes free.

Next, a mobile management system using a mobile management apparatus 20 according to an embodiment of the present invention will be described with reference to FIG.
This will be described in more detail with reference to (a) and (b).

An output of the GPS antenna 1 is connected to an input of a locator device 2 having a GPS receiver (not shown), and the locator device 2 processes a GPS signal from the GPS antenna 1. The output of locator device 2 is connected to digital mobile phone 3.

The signal received by the GPS antenna 1 is processed by the locator device 2 and transferred to the digital mobile phone 4 via the digital mobile phone 3.

Typically, the digital mobile phone 3
The exchange of wireless signals between the mobile phone 4 and the digital mobile phone 4 is performed via a public line network (not shown).

The plurality of digital portable telephones 4 are connected to a line controller 5. The line controller 5 is connected to the RS 23
It is connected to one port of RS232C of the personal computer 6 through the 2C line. The plurality of GPS data input to the digital mobile phone 4 are controlled by the line control device 5 and displayed as the position of the moving object 10 on a map displayed on the monitor device 6 ′ of the personal computer 6.

The line control device 5 includes the same number of data adapters 7 as the number of telephone lines for controlling a plurality of telephone lines, a CPU 8 for controlling the data adapter 7, and an RS232C interface 9 for connecting the CPU 8 and the personal computer 6. Have. The line controller 5 performs telephone line control with a plurality of mobile units including the mobile unit 10, and sequentially reports information from each mobile unit to the personal computer 6. Further, based on a polling command from the personal computer 6, the telephone line connection / disconnection control is performed.
The CPU 8 has a memory 8 'and registers the contents of the transferred data in the memory 8'. The registered data is RS2
After confirming that the 32C interface 9 can be used, a data transfer process is performed.

FIG. 2 shows the flow of data. CPU 8
When a vehicle call command 11 having the ID number of the moving body (vehicle) 10 is received from the personal computer 6, the data (vehicle call command) is registered in the area 15 of the memory 8 ', and the vacant data adapter 7 is selected. The data is transferred to the data adapter 7.

The data 1 reported from the mobile unit 10
3 is registered once in another area 16 of the memory 8 ′ in the CPU 8 via the data adapter 7. PC 6 and CP
When the line to U8 becomes available, a report 14 to the personal computer 6 is made.

The use of the line controller 5 according to the present invention makes it possible to reduce the apparent data communication time with the mobile unit as viewed from the personal computer 6.

Now, it is assumed that one data communication time on one telephone line (a processing time for making a call and disconnecting the telephone) is about 20 seconds. Here, assuming that the line controller 5 can control five lines, the personal computer 6 notifies the line controller 5 of one polling command and the ID numbers of the five mobile units. The line controller 5 sequentially connects telephones to five mobile units via five lines.
Data collection from one mobile station.

The CPU 8 performs only telephone line control,
The reports sent from the mobile station 10 are collectively reported to the personal computer 6. The personal computer 6 uses the ID number and the GPS data (position dynamic information), which are supplied from the line control device 5, for application. Theoretically, the time required for calling the line controller 5 from the personal computer 6 and receiving an answer is considered to be 20 seconds. However, since there are five pieces of information about the mobile unit returned, 20 /
It is considered that 5 = 4 seconds. In practice, the loss of calling from the first mobile to the last mobile is added to this.

In the conventional mobile unit management apparatus, as described above, since the data adapter 7 is directly connected to the personal computer 6, the number of interfaces of the personal computer 6 is limited (usually up to two). Since the line control is performed, the processing becomes complicated, and other problems cannot be performed while a telephone call is being made.

On the other hand, the effects of the mobile management apparatus 20 according to the above-described embodiment of the present invention are as follows.

(1) The programming process of the personal computer 6 is reduced. (2) It is no longer limited by the number of interfaces of the personal computer 6, and a line suitable for the system can be selected. (3) The apparent data communication time is shortened, and the system processing speed is improved.

[0031]

As described above, according to the present invention,
A mobile object management device can be obtained in which the personal computer only needs to transmit the mobile object ID number and the call command, and does not need to perform a call process based on the mobile object ID number and the call command in the personal computer. .

Further, according to the present invention, the number of portable telephones that can be accommodated in the mobile management device is not limited by the number of interfaces of the personal computer, and the personal computer can efficiently perform processing. A mobile management device is obtained.
