Hereinafter, an embodiment of the present invention will be described with reference to the drawings.

FIG. 1 shows the overall configuration of a station automatic ticket gate system to which the present invention is applied, wherein A is a wireless card, and B is a gate management device installed at a ticket gate. The wireless card A stores and issues information as a commuter pass and information as a stored fair. The gate management device communicates information with the wireless card A when the carrier of the wireless card A presents the wireless card A at a predetermined position of the gate management device B. Based on this, the entry / exit of the carrier is permitted (gate open) and rejected (gate shut off).

FIG. 2 shows a specific configuration of the wireless card A. In FIG. 2, the transmission radio wave from the gate management device B captured by the reception antenna 11 is led out to the receiver 12 and amplified and detected. The received signal detected by the receiver 12 is demodulated by a demodulator 13 to extract a digital information signal. This information signal is input port as serial data
The data is taken into the data processing unit 15 via the data processing unit 14 and subjected to data processing.

Here, the data processing unit 15 includes a processor 151, a clock generator 152, and a memory 153.
The processor 151 includes a program counter, an accumulator, a general-purpose register, and the like, and is integrated. The clock generator 152 is an oscillation circuit stabilized with a crystal resonator or a ceramic resonator.
A clock signal for operating the processor 151 at a constant speed is generated. The memory 153 includes a program RAM (random access memory) a and a data storage RAMb. The program RAMa stores a procedure (program) for operating the processor 151 in a predetermined order. The data storage RAMb stores input data.

The program RAMa is further roughly divided into a control program RAMa1 and an execution program loading RAMa2. The control program stored in the control program RAMa1 is common to all wireless cards, is mounted at the time of manufacture, and is not changed thereafter. For this reason, the control program RAMa1 can be replaced with a ROM (read only memory) that cannot be rewritten from the beginning. On the other hand, the execution program loading RAMa2 is in the normal state,
Is loaded.
Here, a processing program as a commuter pass and a processing program as a stored fair are shown. In the data processing unit 15, data write / read operation is performed according to the program loaded here.

Data output from the data processing unit 15 having the above configuration includes:
After undergoing a certain modulation by a modulator 17 via an output port 16, the signal is amplified by a transmitter 18 and transmitted to a space from a transmitting antenna 19 at a certain data rate.

On the other hand, as shown in FIG. 1, a transmission / reception antenna for transmitting / receiving data to / from the wireless card A is provided.
21, a transmitter / receiver 22, a modulator / demodulator 23, and a human detection device for detecting that a person has entered the gate (for example, capturing the visual field image using an infrared sensor or an imaging camera, etc. to detect the presence of a human) 24) that detect the The human detection information from the device 24 is sent to the system controller 25.

The system controller 25 controls the entire system as a whole. Specifically, when the human detection information is received, the read / write device 26 generates an information request signal. When this information request signal is sent to the wireless card A through the wireless transmission system, the stored information is read out from the wireless card A, and taken into the read / write device 26 through the wireless reception system, the card information is collated,
If it is correct, an open signal is given to the gate device 27 to open the gate, and if an error is made, a shutoff signal is given to the gate device 27 to put the gate in the shutoff state.

When the collation is completed, the system control device 25 generates an account command signal for the stored fair in the read / write device 26, sends the signal to the wireless card A via the wireless transmission system, and controls the rewriting of the contents of the data storage RAMb. Further, when the execution program of the wireless card A is changed, when the collation is determined to be correct, the modification program stored in advance in the modification program storage memory 28 is read as a valid wireless card. At the same time, the read / write device 26 generates a correction request signal, which is sent to the wireless card A via the wireless transmission system.

The operation of the above configuration will be described below with reference to the flowchart of FIG.

First, the inside of a predetermined area of the gate is monitored by the human detection device 24 (step a), and the presence or absence of a person is determined (step b). Here, when the presence of a human is not detected (NO)
The monitoring operation of step a is repeated, and if detected (YES), the storage information is requested from the wireless card A (step c), and the wireless card A obtained by this request is further obtained.
(Step d)
The correctness is determined (step e). Here, when the result of the collation is determined to be “error” (NO), the gate is shut off (step f), and when it is determined to be “correct” (YE
In S), it is determined whether account processing is necessary based on the information from the wireless card A (step g).

Here, if account processing is required (YES), an account instruction signal is sent to the wireless card A to execute the account processing (step h), and if unnecessary (NO), whether the program is directly corrected is determined. Is determined (step i). Here, if correction is necessary (YES), the memory 28
Read a correction program stored in advance, and generate a correction request signal in the read / write device 26,
These are sent to the wireless card A to correct the execution program (step j). If no correction is necessary (NO), the gate is directly opened (step k), and the series of operations is terminated.

Therefore, the automatic ticket gate system having the above configuration can execute the program modification of the card A on the gate monitoring device B side at the time of the ticket gate by using the wireless card whose execution program can be modified, so that it can be easily used as required. For example, diversification such as a change in the pre-bate or stored fair account function and a case where it is desired to change only the regular issuance card to a new processing program can be realized.

In the above embodiment, the card is used as the information storage medium. However, the present invention is not limited to this. Further, the present invention is not limited to a station ticket gate, and the same effect can be obtained even when used in a tollgate on an expressway.

[Effects of the Invention] As described above, according to the present invention, it is possible to provide an automatic entry / exit management system that can easily modify and diversify applications as needed.
