Parking Guidance for Automated Parking Garages

The system installs a wireless surface-mounted ultrasonic space detector at the centre of each automated parking-garage carrier plate and a wireless space indicator above each garage group. 

The detector sends space status to the indicator for its garage group. The indicator aggregates the status of all spaces and shows green when a space is available and red when the group is full. 

It then encodes and sends the group status to a wireless area controller. The central controller aggregates all area-controller data, processes it and updates the remaining-space count shown on guidance displays.

System Advantages

The system increases the intelligence and digitalisation of the car park, transfers manual work to intelligent devices and ensures timely, 

accurate and effective data. Drivers can use the guidance equipment to find a space quickly and conveniently.

Surface-mounted ultrasonic space detector

The detector uses ultrasonic ranging to obtain space status and sends it wirelessly to the indicator for its garage group.

Product advantages:

1. Attractive, technology-oriented design that improves the image of the car park.

2. Two independent transmit/receive circuits and an advanced anti-interference algorithm deliver detection accuracy above 99%.

3. Wireless communication avoids difficult cabling, installation and maintenance in automated garages and reduces construction cost and time.

4. Ultra-low-power design and a high-capacity built-in battery provide three to five years of operation without external power.

5. Wireless mobile-app commissioning shortens the commissioning cycle and simplifies the process.

Wireless space indicator

Installed in front of each garage group, the indicator aggregates the group status wirelessly and shows red when full and green when spaces are available. 

It then uploads the group status to the corresponding wireless area controller.

Product advantages:

1. Attractive, technology-oriented design.

2. High-brightness LED indicators with long service life, long viewing distance and a wide viewing angle.

3. Automatic management of the number of spaces in the group without software binding.

4. Independent calculation of available spaces prevents a controller communication failure from bringing down the entire system.

5. Multi-channel wireless networking reduces internal interference and external wireless crosstalk.

6. A patented multi-level intelligent wireless routing link supports complex environments such as pit-type automated garages.
