Description

Technical Field

[0001] The utility model relates to the technical field of blind-assistance obstacle avoidance equipment, in particular to a public transportation assistance device for the visually impaired. Background Art

[0002] At present, with the continuous improvement of barrier-free laws and regulations, barrier-free travel has become a focus of promotion. Taking the bus for visually impaired people is the first step to help them integrate into society.

[0003] However, most of the existing buses are not equipped with bus guidance systems for the visually impaired when they leave the factory, and all need to be installed later. The bus guidance equipment available on the market basically consists of several devices such as Bluetooth positioning devices, GPS positioning devices, external speakers and on-board guidance terminals, which need to be installed in several different locations on the bus, increasing the manual workload of installing the equipment. Multiple power sockets also pose certain safety hazards to the normal operation of the bus.

[0004] In order to enable visually impaired people to determine the location of the bus based on the sound, the voice announcement speaker should be placed as close to the door as possible. Both the on-board guidance terminal and the positioning equipment need to be powered inside the bus. Some on-board guidance terminals have voltage limitations and certain requirements for the power supply location inside the bus, which makes it difficult to integrate the bus guidance equipment on the market.

[0024] Please refer to the attached Figures 1 to 3 The present application provides a bus travel assistance device for the visually impaired. The assistance device includes a shell, which is installed at the door of the bus. A Bluetooth module 1, a GPS module 2, a 4G communication module 3, an audio component 4, a power management component 5 and an MCU controller 6 are arranged inside the shell. The Bluetooth module 1, GPS module 2, 4G communication module 3, and audio component 4 are all connected to the MCU controller 6. The MCU controller 6 realizes data interaction with the server 8 through the 4G communication module 3. The power input end of the power management component 5 is electrically connected to a charged component on the bus, and its output end supplies power to the Bluetooth module 1, GPS module 2, 4G communication module 3, audio component 4, and MCU controller 6 in turn.

[0025] Specifically, the bus travel assistance device for the visually impaired provided in the embodiment of the present invention is used to help the visually impaired determine the door position of the bus. When in use, the assistance device is first installed at the door of the bus and powered by a charged component on the bus. The assistance device installed on the bus sends its own location information to the server 8 through the GPS module 2. At the same time, the visually impaired person receives the aforementioned location information through the handheld terminal. When the bus arrives at the station, the handheld terminal held by the visually impaired person sends a Bluetooth signal to the assistance device. After receiving the Bluetooth signal, the Bluetooth module 1 in the assistance device sends the parsed data to the MCU controller 6, and the MCU controller 6 drives the audio component 4 to play the station voice. Since the assistance device is set at the door, the visually impaired person can identify the location of the door by hearing the played voice, and can also know the name of the current station.

[0026] In an optional embodiment, the power input end of the power management component 5 is electrically connected to the vehicle-mounted LED scrolling screen through a three-way connector.

[0027] Furthermore, the power management component 5 includes a voltage regulator 51 and a fuse 52. The three-way connector is connected to the voltage regulator 51 through the fuse 52. The output end of the voltage regulator 51 is electrically connected to the Bluetooth module 1, GPS module 2, 4G communication module 3, and audio component 4 respectively.

[0028] Specifically, a three-way connector is used to connect to the vehicle's LED scrolling screen for power. The positive cable is then connected to the voltage regulator 51 after being insulated with a 2A fuse 52. This does not affect the normal operation of the original vehicle's LED scrolling screen or damage the original vehicle's cables. The fuse 52 is used to protect the circuit from overcurrent, and the voltage regulator 51 is used to achieve voltage regulation. If the voltage provided by the vehicle is higher than the operating voltage required by the auxiliary device, a voltage regulator 51 is required to reduce the input voltage to an appropriate level.

[0029] In an optional embodiment, the audio component 4 includes a speaker, and the arrival voice is played through the speaker.

[0030] In an optional embodiment, the Bluetooth module 1, GPS module 2, 4G communication module 3, and power management component 5 are integrated into a circuit board, and the circuit board is fixed to the bottom box of the housing.

[0031] In an optional embodiment, the audio component 4 is fixed to the upper shell of the housing.

[0032] In addition, when installing the housing at the bus door, it complies with the following installation requirements:

[0033] a. The device should be fixed on the right front reflector of the vehicle as close to the vehicle body as possible.

[0034] b. The cable is fixed to the reflector bracket with a rolled tape;

[0035] c. Use a hole punch (5mm) to make a hole in the rubber strip on the upper right corner of the vehicle's front door;

[0036] c. The cable enters the vehicle through the hole in the right front door;

[0037] d. After the cable enters the vehicle, secure it to the right front A-pillar using a 3M clip, avoiding the right front door steering column.

[0038] e. The cable enters the top of the front end of the vehicle through the gap above the windshield on the right front A-pillar;

[0039] f. The cable is at the top of the front end of the vehicle, that is, in the headlight box above the driver's head. Use a rolling tape to fix the cable every 20CM.

[0040] It should be noted that the Bluetooth module 1, GPS module 2, and 4G communication module 3 are all hardware modules with hardware entities, and the Bluetooth module 1, GPS module 2, 4G communication module 3, audio component 4, power management component 5, and MCU controller 6 and other components are all conventional components of those skilled in the art, and their structural composition and models are common knowledge of those skilled in the art, and are not elaborated in detail in this embodiment.

[0041] The above are only specific embodiments of the present invention, but the scope of protection of the present invention is not limited to them.
