HDT280

HEAVY DUTY TERMINAL

HDT280_hp001S

AndroidOS / HARDWARE

The HDT280 is a durable multi-function terminal that comes with the Android OS. Fitted with a touch panel, it provides intuitive operation. It can run a wide variety of work site and business oriented applications, and through the use of original applications developed by the user, the HD280 can be customized as a specialized device.
Because Android was originally developed for connection to networks and the Cloud, it is particularly suited to the construction of network type system applications.

Durability

Its durable design is well suited to the demanding environment of work sites.
The HDT280 is made for use as a highly reliable client terminal at locations in extreme environments, such as on construction and earthworks equipment, in manufacturing factories, warehouses, external structures and at sea. It conforms to the United States Department of Defense military standard (MIL-STD810G) for shock-proof and vibration-proof capability, as well as the IP67 waterproof standard, in addition to the salt water spray standard (ASTM B-117) in the case of use in marine and coastal environments.

Functionality Meeting the Needs of Work Sites

  • LED lights and a high volume speaker (80 dB) for issuing warnings
  • High brightness monitor made to be visible in outside light (1000 cd/m2)
  • Can operate using a wide range of voltages (10.8 VDC – 36 VDC)
    Internal battery (3.5 hours operating time) provides reliable power supply

GNSS FUNCTION

Fitted with two high-precision L1-RTK GNSS modules that allow measurement with accuracy on the order of a few centimeters. Compatible with global navigation system satellites (GPS, GLONASS, Beidou, SBAS, QZSS)

The L1-RTK GNSS Rectifies Previous Shortcomings

The current model improves the initialization time and recovery time from cycle slips, which were a problem previously with L1 position measurement. Compared to L1+L2 position measurement, it can be used as a high cost performance RTK GNSS device. In addition, as there is an LTE module in the unit, it can be used by itself for network type RTK position measurement.

W-GNSS Compass

Thanks to its two RTK GNSS modules/antennas, the HDT280 operates as a high-precision GNSS compass. Used on its own, the HDT280 can be utilized in a variety of situations, such as measurement of the progress of moving bodies, guiding of heavy machinery, work ships, etc., with positioning guidance, and measurement of the positions of the tips of cranes on special vessels such as crane barges.

SENSOR NETWORK / CLOUD

The HDT280 was designed to be connectable to sensors, heavy machinery and manufacturing machinery as required in i-construction, and to cloud networks.

i-construction

In earthwork construction machine guidance and the measurement of 3D work progress data following compaction operations, high connectability to heavy machinery and operator friendly operation are required. With the HDT280, such functions can be built into or added later onto heavy machinery.

LTE Cloud Connection

A 5-band LTE module is fitted as standard, providing a constant cloud connection environment. LTE can use either the internal antenna or an external one, providing greater freedom when choosing an installation location. Equipped with a Wi-Fi (802.11 b/g/n)/Bluetooth 4.0+LE communications function, and, integrating all kinds of sensors and devices, it can be incorporated into a system as a high-performance central IoT central device.
