DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a vehicle dynamics management system, and more particularly to a vehicle dynamics management system that enables a command vehicle to easily grasp the dynamics of a general fire vehicle.

[0002]

2. Description of the Related Art A conventional vehicle dynamics management system uses a dynamics management device at a headquarters as described in JP-A-5-22208 and JP-A-58-144999 to grasp the dynamics and position of a vehicle. Centralized management.

[0003] This conventional example will be described with reference to FIG. When the general fire vehicle performs dynamic registration, a dynamic registration signal 71 is processed by the vehicle dynamic management device at the headquarters, and a confirmation signal 72 is sent to the general fire vehicle. Further, the management device registers the dynamic state (including the vehicle ID number and the dynamic state code) with the host computer. This dynamic registration may be performed from a plurality of vehicles. When performing a digestive activity at a site, a command vehicle that is in command of the site needs to know the activity status of the vehicle during the site activity. At this time, another vehicle dynamics request 74 is made to the vehicle dynamics management device. Upon receiving the other vehicle dynamics request 74, the vehicle dynamics management device sends a request signal 75 to the host computer.
Is sent. Upon receiving the request signal 75, the host computer sends the dynamic information registered in the dynamic registration 73 to the vehicle dynamic management device as other vehicle dynamic information 76. The vehicle dynamics management device sends other vehicle dynamics information 77 to the command vehicle. The other vehicle dynamics information 77 received by the in-vehicle wireless device of the command vehicle is displayed on the terminal device, and the status of the other vehicle is grasped by the command vehicle.

[0004]

In this conventional system, the dynamics of a general fire-fighting vehicle stored in a host computer are transmitted as other vehicle dynamics information in response to a request from a command vehicle. The command vehicle needs other vehicle dynamics information during firefighting and other on-site activities, and when radio communication is extremely busy, occupy a wireless line to acquire other vehicle dynamics information Will hinder smooth activities.

[0005]

A vehicle dynamics management system according to the present invention includes a terminal device for inputting dynamics, and a vehicle-mounted wireless device for transmitting a dynamic signal from the terminal device to a vehicle dynamics management device at the headquarters. A terminal device for inputting a dynamic and displaying the dynamic of the general fire vehicle having the same activity code ; transmitting a dynamic signal from the terminal device to the vehicle dynamic management device; and controlling the vehicle dynamic management device A command vehicle having an in-vehicle wireless device for receiving the dynamic signal of the general fire vehicle from the vehicle; receiving the dynamic signal transmitted from the general fire vehicle and the command vehicle and transmitting the dynamic signal transmitted from the vehicle dynamic management device a radio device that performs the transmission of the confirmation signal, and the vehicle dynamics management device for sending an acknowledgment signal subjected to reception of the dynamic signal, the vehicle number and activity transmitted from the vehicle dynamics control apparatus And a headquarters with a host computer for managing the dynamics including over de, said managed by the host computer to the confirmation signal transmitted from the vehicle dynamics management apparatus to the general fire engines and the command vehicle vehicle through the wireless device This is a configuration for adding a dynamic that includes the activity code that is being used.

DESCRIPTION OF THE PREFERRED EMBODIMENTS Next, the present invention will be described with reference to the drawings. 1 and 2 showing an embodiment of the present invention.
Referring to FIG. 3 and FIG. 6, a dispatch instruction is issued to the corresponding station by the 119th incoming call, and the general fire truck 10 and the command vehicle 11 are dispatched. These vehicles are terminal devices 101, 1
11, the dynamics registration is performed, and dynamics registration signals 21 and 22 are supplied to the vehicle dynamics management device 122 of the head office 12 through the on-board wireless devices 102 and 112 and the wireless device 121. The vehicle dynamics management device 122 receives the signal,
The dynamic registration text (see FIG. 6A) 23 is sent to the host computer 123. Host computer 123
Receives the text, and sends another vehicle status text (see FIG. 6B) 24 to the vehicle dynamics management device 122.
However, when there is no change in the vehicle condition, that is, when there is no dynamic change, the transmission is performed with the number of vehicles “0”, and the information after the vehicle ID 1 in the text shown in FIG. 6B is not transmitted. Upon receiving the text 24, the vehicle dynamics management device 122 receives the vehicle 10,
11 to the terminal devices 101 and 111 (FIG. 6 (c)).
25) is sent. At this time, if the number of vehicles in the other vehicle status text is “0”, the confirmation signal is transmitted with the number of vehicles. Registration is completed when the terminal device 101 of the general fire vehicle 10 receives the confirmation signal 25. In the terminal device 111 of the command vehicle 11, the confirmation signal 25 includes the number of vehicles, and if the activity codes match, the vehicle status is loaded into the memory.
FIG. 3 shows the operation of the command vehicle vehicle 11 of the fire department from dispatch to return home in accordance with the dynamic registration operation. As described above, the erasing of the memory of the vehicle status captured by the command vehicle is executed when the command vehicle registers the return.

FIG. 4 shows an operation flow of the vehicle dynamics management device and the host computer. Upon receiving the registration signal from the general fire truck 10, the vehicle dynamics management device 122 sends a dynamic registration text to the host computer 123. The host computer 123 registers in the vehicle dynamics file based on the sent registration text, and sets “1” in the transmission history status. Further, the host computer 123 transmits the vehicle I of the received registration text.
It is determined from the D number whether the vehicle is a general fire vehicle or a command vehicle, and if it is a general fire vehicle, only the vehicle of the registered text received in the other vehicle status text is returned. If the vehicle is a command vehicle, the transmission history status in the past is checked, and the status with the status "1" is transmitted as the other vehicle status text. The vehicle dynamics management device 122 sends a confirmation signal to the vehicle based on the other vehicle status text.

FIG. 5 shows an operation flow of the vehicle. The general fire-fighting vehicle 10 performs a dynamic registration operation, and the registration is completed by receiving a confirmation signal from the headquarters. In addition, the command vehicle 11 receives the confirmation signal from the headquarters, compares it with its own activity code,
If they match, they are stored in the memory as other vehicle dynamics information, and if they do not match, they are discarded. This is because only the information of other vehicles being dispatched under the same requirements is taken in.

The transmission of various signals between each vehicle and the vehicle dynamics management device is performed by transmitting the same information three times in succession to ensure reliability.

[0010]

As described above, according to the present invention, the command vehicle transmits the information using the confirmation signal from the headquarters without requesting the command vehicle newly to obtain other vehicle dynamic information. In addition, it is possible to suppress the time that the radio line is occupied when the radio line is congested during the on-site activity.
