Description

TECHNICAL FIELD [0001] The present invention relates to an integrated gait-

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an integrated gait signal voice guidance assistant device, and more particularly, to an integrated gait signal voice guidance assistant device for detecting an operation of a pedestrian in a crosswalk of a road, .

A conventional gait signal sound guidance assistance device includes a bollard as an obstacle on both sides of a pedestrian crossing and an infrared sensor that is straight in the bollard. When the pedestrian is a red signal, the pedestrian is released from the sidewalk And is configured to detect and warn the case.

The gait signal sound guidance assistance device is provided on both sides of a transverse walkway for walking the bollard equipped with an infrared sensor for sensing a pedestrian, a separate control unit is provided, and a smart speaker is separately provided.

In this case, since the bollard is installed on the pedestrian's pedestrian crossing, frequent contact with the pedestrian may cause the detection direction in the bollard to be distorted or broken, and the infrared sensor in the bollard may be broken.

In addition, the gait signal audio guidance auxiliary device having an infrared sensor in a conventional bollard has a problem in that it is difficult to maintain and install the bollard, the control unit, and the smart speaker separately.

In order to improve these points, a technique has been developed in which a pedestrian sensor, a control unit, and a smart speaker are integrally constructed and installed at the top of a traffic light.

The above technique employs a heat ray sensor (PIR) as a pedestrian sensor. Accordingly, there is a problem that a malfunction due to exhaust gas discharged from the vehicle, geothermal heat in summer, and various heat sources around the sensor occurs. In addition, the thermal sensor has a disadvantage in that the reaction time for transmitting and processing the detection time and the detection signal in the control unit is slow.

On the other hand, a technique of using a pedestrian detection sensor as an image sensor has been developed. This technique has a problem that detection by an image can not accurately detect a pedestrian. That is, since the image sensor senses all the objects to be operated, the detection error is generated too easily, so that the use of the sensor is impossible in the gait signal audio guidance assistant.

In addition, a voice guide for the visually impaired is installed at the entrance of the crosswalk on both sides of the crosswalk. Conventional voice guidance devices for the visually impaired are configured such that the visually impaired person grasps the position by the touch and broadcasts the crosswalk announcement message for the visually impaired by pressing the button.

Such conventional voice guidance devices for the visually impaired are installed separate from the above-described voice guidance device for gait signals, thereby making the appearance of the crosswalk complicated on both sides, thereby deteriorating the beauty of the city and hurting the safety of walking.

■ MQTT communication description

MQTT is a lightweight Publish / Subscribe (Pub / Sub) messaging protocol. The MQTT protocol is based on the principle of publishing messages and subscribing to topics of interest.

[Service configuration of MQTT communication method]

Pub and Sub operate on a topic. MQTT is a message bus system. When the MQTT Broker creates a message bus and sends a message to it, it is the way applications on the bus read the message. Message buses can have various topics of messages. To distinguish messages, a message channel named "Topic" is created.

4.3.9 [System Status] Section Description

Displays the operation status of the device as a log. If the communication terminal does not communicate with the communication terminal every 100 counts, if the communication terminal does not communicate with the PSeye, the log is recorded every 30 minutes. (Example below)

4.3.10 [Device Search], [Communication Statistics], [Server Communication] Section Description

[Device search] can select the device by inputting device installation location information when there are many devices registered in the [device list] area.

The Device Statistics section provides statistical information about the status of communication between registered devices and the server.

The [Server Communication] section displays the communication status between the PSeye monitoring program and the MQTT Broker.
