Abstract

PURPOSE:To exactly distinguish a vehicle out of a control object by outputting a specified signal by a radio so as to show that the vehicle is out of the control object. CONSTITUTION:When the existence of a vehicle 5 violating the speed limit is detected by a detection signal from a speed detection part 1, a control part 3 transmits and outputs an access signal to an IC card 7 carried into the vehicle 5 so as to obtain required control information for dealing with the driver of this vehicle 5 as a speed-limit violator. When this access signal is received, the IC card 7 returns and outputs a required control information signal for control stored in a memory 15. Thus, it is exactly whether the vehicle is special one or not, and the violation of speed limit can be suitably controlled.

For example, in the case of managing speeding violations mentioned above, police cars, fire trucks, ambulances, etc. are excluded. Therefore, in performing appropriate management, it is important to accurately distinguish whether a vehicle is a managed vehicle or not, and measures for this purpose have been desperately needed.

The present invention has been made in view of the above, and an object of the present invention is to provide a vehicle management system that can accurately distinguish vehicles that are not subject to management.

[Structure of the Invention] (Means for Solving the Problems) In order to achieve the above object, necessary management of a vehicle is performed via a portable medium equipped with a wireless information transmission function brought into the vehicle by the driver. In the system, the present invention provides a function that is provided in the portable medium and wirelessly outputs a specific signal indicating that when the vehicle is not subject to management in response to wireless access from a management device outside the vehicle. The main point is to have the following.

(Function) The vehicle management system according to the present invention is provided in a portable medium equipped with a wireless information transmission function brought into the vehicle by the driver, and is configured to provide wireless access from a management device outside the vehicle. When the vehicle is not subject to management, a specific signal indicating this fact is wirelessly output.

(Example) Hereinafter, the present invention will be explained in detail using the drawings.

This vehicle management system particularly manages speeding violations, and 1 is a speed detection section and 3 is a management section, both of which constitute a management side device. Reference numeral 5 denotes a vehicle which is the managed side, and inside the vehicle is an I/O device that constitutes a portable medium brought in by the driver.
C card 7 exists.

FIG. 2 is a diagram showing the configuration of the IC card 7. As shown in FIG.

The IC card 7 has a configuration including an antenna 9, a receiving circuit 11, a control circuit 13, a memory 15, a transmitting circuit 17, and a battery 19, and performs various exchanges with the management section 3 for management using wireless signals. It is. The control circuit 13 is I
It controls the operation of the entire C card 7, and is composed of, for example, a microcomputer. The memory 15 is the third
As shown in the figure, it is used to store at least management information such as vehicle number regarding the management of the vehicle 5, especially when the vehicle 5 is a vehicle (special vehicle) that is not subject to management for speeding violations such as a police car. In some cases, for example, special vehicle classification, name of the responsible organization, driving sound name, etc. are also stored.

Next, the operation of this embodiment will be explained using the processing flowchart of the management section 3 shown in FIG.

When the management unit 3 detects the presence of a speeding vehicle 5 based on the detection signal from the speed detection unit 1, the management unit 3 detects the speeding vehicle 5 in order to obtain necessary management information in order to dispose of the driver of this vehicle 5 as a speeder. I brought into the car of
An access signal is transmitted and output to the C card 7 (steps 100 to 120). Upon receiving this access signal, the IC card 7 outputs in response a necessary management information signal for management stored in the memory 15. The management department 3 is
When this management information signal is received, it is first determined whether the vehicle 5 is a special vehicle or not (step 140). If the vehicle is not a special vehicle, a predetermined process for normal violation punishment is executed (step 150). However, if it is a special vehicle, the vehicle number, special vehicle classification, name of the organization in charge, and driver information are recorded for confirmation without processing for violation.
Step 160).

Therefore, according to this embodiment, since it is possible to accurately distinguish whether the vehicle is a special vehicle or not, appropriate management against speeding violations can be realized.

In this embodiment, although the management of speeding violations has been described, the present invention is similarly applicable to other regulations such as parking violations.

Further, the transmission between the management unit 3 and the IC card 7 may be encrypted information to ensure security.
