Hardware Devices Layer (HDL)
It is the layer that allows iPlace to abstract from the peculiarities of the different hardware devices that are going to communicate with it. Any device or hardware sensor can be easily integrated by creating a controller (iPlace Driver) that implements the communication protocol used by that terminal. In this way, iPlace already has drivers developed to communicate with proprietary devices, such as fire and gas power plants, electric meters, devices located in a service station (pumps, tanks, etc.).
In addition, iPlace has a wide range of proprietary hardware devices called iPlace Controllers. There are several types depending on the type of connection they use:
- Serial: are devices that are connected to iPlace through a serial connection.
- Ethernet: in this case the connection is through a local wired network.
- Wi-Fi: also connected within a local network, but they do it wirelessly. They can be powered by a battery or the electricity grid.
This proprietary hardware allows all types of inputs and outputs, both digital and analog. They also offer the possibility of connecting peripherals that use protocols such as Wiegand or 1Wire (temperature sensors, humidity, keyboards or RFID access cards).
It should be noted that these controllers (iPlace Controllers) have a fully optimized firmware to work with iPlace, which allows:
- Optimize the communication protocol with by sending a reduced frame relay and only when an event occurs.
- Parameterize refresh times, sensor sensitivity, etc.
- In the case of Ethernet devices, they have the ability to find devices in the network in a completely transparent for the IP protocol.
