Digital Trunking & Data Comm.
Background
Data and voice communication are indispensable for terminal dispatching. Early voice communication is basically achieved by narrow-band intercom, and additional communication service fees are required. Whereas, data communication is accomplished by running TOS system on in-vehicle data terminals. To help save the cost of network devices, Darveen has launched in-vehicle computers integrating data and voice communication.

Requirements for the Solution
All-in-one in-vehicle computer touchable display.
PTT function intercom.
Built-in wireless communication module.
Mounting bracket.
Wide-voltage waterproof power supply.

Solution
Darveen in-vehicle computers can be equipped with intercoms with PTT (Push-to-talk) function, and a trunking scheduling software. In this way, trunking intercom function on WiFi or mobile telephone network can be realized, and more cost can be saved.


Solution Advantages

Save cost for network operation and number of terminals.
Reliable product quality to meet the requirement for 7*24 non-stop operation.
Vehicle standard wide-voltage power input, to support various terminal truck models.
Full Al-alloy enclosure, fanless design, to meet anti-dust, water-proof and anti-salt-fog standards for the terminal environment.

Application Area
Container terminal.
