Problems solved by technology

[0023] As mentioned above, the conventional DSRC vehicle-mounted device does not have a device for alarming when the temperature of the IC card insertion part 9 exceeds the heat-resistant temperature range of the IC card C, so there is a problem that the IC card is damaged due to thermal deformation.

Embodiment Construction

[0042] Embodiment 1 of the present invention will be described below.

[0043] figure 1 , figure 2 In order to show the sectional view and functional block diagram of Embodiment 1 of the present invention, image 3 to show figure 2 Flowchart of the operation of the on-board device controller in the

[0044] exist figure 1 , for the above ( Figure 6 ) are marked with the same symbols, and detailed descriptions are omitted.

[0045] 11 and 12 are temperature sensors disposed near the IC card insertion portion 9, which detect the ambient temperature of the IC card C when the IC card C is inserted. Here, in order to improve the reliability of the temperature information, two temperature sensors 11 and 12 are shown, but any number or at least one temperature sensor may be provided.

[0046] Each temperature sensor 11,12 is arranged on the circuit board 8 and is located in the IC card insertion part 9, wherein one temperature sensor 11 is arranged near the electrode part ...

Abstract

A DSRC car-mounted equipment which prevents an IC card from being inserted when the temperature lies outside a tolerable temperature range, in order to avoid the thermal deformation and low-temperature breakage of the IC card. The DSRC car-mounted equipment comprises a communication control unit for executing a dedicated narrow-range communication with an on-the-road equipment 1, an IC card accommodation portion 9, a contact portion 10 connected to an electrode portion D of the IC card, a car-mounted equipment controller for reading and writing data to, and from, the IC card, a circuit board 8 constituting the IC card accommodation portion, temperature sensors 11 and 12 disposed near the IC card accommodation portion, a temperature-judging unit for judging whether the temperature data are within the temperature range tolerated by the IC card, and alarm unit 6 and 7 for producing an alarm when the temperature data lie outside the tolerable temperature range.

Description

technical field [0001] The present invention relates to a vehicle-mounted device for Dedicated Short-Range Communication (hereinafter referred to as "DSRC") used in Intelligent Transport Systems (Intelligent Transport Systems) (hereinafter referred to as ITS) such as ETC (Automatic Road Toll Collection System), in particular to Among DSRC vehicle-mounted devices that use IC cards for data processing, it is a DSRC vehicle-mounted device that prevents the insertion of IC cards at high or low temperatures and prevents thermal deformation of IC cards. Background technique [0002] Generally, IC cards functioning as detachable external storage media are used in DSRC vehicle-mounted devices used in ITS (ETC, etc.). As is well known, an IC card is activated by inputting a password, stores personal information (fee payment data, etc.), and can be read out as necessary. [0003] Figure 6 To schematically show the block diagram of the traditional DSRC vehicle-mounted device, in Fig...
