Direction and Amount of Free Parking Spaces LED Signs – Use Case

With this use case we demonstrate how to use our LED message signs to display the amount of free parking spaces for the drivers.

We go through the use case example with our two products. The upper LED sign is our model DS-320×160-P8 and the lower one is model DS-320×320-P8.

Both models are full color and with pixel pitch P8. Suitable for outdoor and indoor use.

Configuration and Setup

To set things up at the beginning, we need to add layout information to the JSON files. ( want to know more about our AmpronLED communication protocol software? Go read at Software page)

In the server we configure the layout file for the upper LED message board model DS-320×160-P8 as follows:

We will not cover too many details here, just to keep things simple. If you want to read more about the AmpronLED configuration, you can do it on our API page. Will just mention that this configuration has information to display text, at full message board area, aligned at center, with font size 18 and font color white.

For the model DS-320×320-P8 LED message board, we create a bit more creative layout. Lets create two areas - one (TEXT) for the upper part and other for the lower part (PICTURE):

Of course, there are many more configurations and layers that you could do, but for starters, let's keep it simple.

Sending information

Information sending is done through our AmpronLED server application. It acts as router. In simplified form: it works same way as you browse web. You type the web address and server sends you back information on your screen. So here you send the address (HTTP GET request) to AmpronLED server application but in this case it forwards content to display controller. That's it.

Now, let's start to send information to the upper display.

Let us assume that AmpronLED is on the server with IP address: 192.168.1.1 and at port 9527.

Sending information to Model DS-320×160-P8

To display the number, we send HTTP GET request:

http:/192.168.1.1:9527/mlds?id=PARKING&layout=FREESPACES&TEXT=034

Result would be on the screen as such:

Ampron Parking Free Spaces Digital Signage DS-320x160-P8

Sending information to Model DS-320×320-P8

To display the amount of free parking spaces and direction, we send HTTP GET request:

http:/192.168.1.1:9527/mlds?id=PARKING&layout=DIRECTION&TEXT=034&PICTURE=RIGHT

Result would be on the LED message board:

That was it. You just learned how to configure our displays and send information for display. To automate things, developers can configure their software side in a way that variables change depending on what would be needed to display on the screen.

Here are some more examples with different layouts and display visuals.
