Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a gate device for controlling traffic using a non-contact card.

[0002]

2. Description of the Related Art Conventionally, a gate device using a non-contact type card reads card data via a radio antenna when a passerby carrying the card approaches a gate entrance.
If it is determined that the card is the predetermined card, a bar or the like installed in the passage is opened to permit the passage.

[0003]

The conventional gate device has the following problems. If the area near the gate entrance is crowded and multiple passers-by cards enter the area where radio waves can be transmitted / received by the antenna, card data cannot be read, or the timing of reading data and detecting the movement of passers-by by sensors is sufficiently coordinated. Sometimes it could not be taken. Therefore, for example, two passers-by enter the gate passage with one card, and the sensor detects the passer-by that passes first and closes the gate. There were cases where traffic was hindered, such as being locked inside, or having to read the card again by approaching the antenna again.

[0004] This inconvenience occurs because a plurality of passers-by can access the radio wave transmitting / receiving area of the antenna at the gate entrance and enter the gate at the same time. On the other hand, there is a known device that detects a pedestrian with an optical sensor or the like and opens or closes a door to permit the passage of the pedestrian. However, there is no device that detects the sensor to actively stop the passage of a subsequent pedestrian.

[0005] It is an object of the present invention to limit the number of pedestrians in a gate to one.

[0006]

A gate device according to a first aspect of the present invention is a gate device for controlling traffic using a non-contact storage medium, wherein a detecting means for detecting a pedestrian in the gate and a subsequent pedestrian are inserted into the gate. A barrier means is provided which does not enter, and a control unit which activates the barrier means while the detecting means detects a pedestrian in the gate.

As a result, while a pedestrian is detected in the gate, the barrier means operates to stop the following pedestrian from proceeding, so that the number of pedestrians in the gate is limited to one. The gate device according to a second aspect is the gate device according to the first aspect,
The detecting means is a weight sensor installed in the gate passage.
As a result, the weight sensor continues to detect the weight of the passerby while the passerby is present in the gate, so that the presence or absence of the passerby in the gate is reliably detected.

The gate device according to a third aspect of the present invention is the gate device according to the first aspect, wherein the detecting means is a limit switch which is installed at each of the passage doors at the entrance and the exit of the gate, and is turned on / off in response to opening and closing of the door. After the operation of the switch at the gate entrance is detected, the operation of the traffic barrier is maintained until the operation of the switch at the gate exit is detected. Thus, the presence or absence of a pedestrian in the gate can be easily detected by a change in the operation state of the switch.

The gate device according to a fourth aspect of the present invention is the gate device according to the first aspect, wherein the detecting means is a pedestrian detection sensor installed at the gate entrance and the exit, and the control unit is configured such that the sensor at the gate entrance detects the pedestrian. After the detection, the operation of the traffic barrier is maintained until the sensor at the gate exit detects a pedestrian. This makes it possible to easily detect the presence of a pedestrian in the gate simply by installing a sensor.

A gate device according to a fifth aspect of the present invention is the gate device according to the first aspect, wherein the barrier means is a breaker that blocks traffic. This ensures that the number of passers-by in the gate is limited to one.

The barrier control device 3 is connected to a weight sensor 8 for detecting a pedestrian 7 in the gate and a traffic barrier 11 for stopping the traffic of a subsequent pedestrian 10 carrying the non-contact card 9.

FIG. 4 is a flowchart showing the operation of the main part of the invention. The operation will be described with reference to FIG. During operation of the gate device, the barrier control device 3 determines whether there is a pedestrian in the gate passage based on a detection signal from the weight sensor 8 (step S1). When a person is not detected (branch N), the passage barrier 11 is not operated (step S2). When a person is detected (branch Y), the traffic barrier 11 is actuated (step S3). When the passer exits the gate and the weight sensor 8 stops detecting the traffic (step S4, branch N), the traffic passes. The operation of the barrier 11 is stopped (Step S5). While the weight sensor 8 is detecting a person (step S4, branch Y), step S3
Returning to the step, the passage barrier 11 is operated.

According to the above operation, if there is a pedestrian in the gate, the subsequent traffic is stopped by the traffic barrier and cannot proceed to the gate, so that the inside of the gate can always be limited to one pedestrian. (2) Regarding Inventions 1 and 3 FIG. 2 is a configuration diagram showing an embodiment of Inventions 1 and 3.
