TBSL1 product line is a range of modular RTUs that comprehends a common platform and a socket for a modem daughter board.

Modem board is then not only interchangeable but also totally plug and play without having to update the platform’s FW.For instance, the user can freely switch from LoRa to 4G by just replacing the modem board .

Beijing Tianyu Communications Equipment Co., Ltd, founded in April 2002, is a professional high-tech company specializing in the R&D, manufacturing and marketing of mobile phones. China USB Hart Modem (SRK-ESH232U), Find details about China Hart Modem, Usb Hart Modem from USB Hart Modem (SRK-ESH232U) - Beijing Shengruike Automstion Equipment Co., Ltd.

Qualcomm has disclosed two license deals it has reached with China-based Haier and Beijing Tianyu Communication Equipment, which will pay the chip firm royalties for using its 3G and 4G wireless.

TBSL1 is designed as a future proof RTU and a very flexible platform for IoT ecosystems.

TBSL1/RFB-LoRa – Multi-sensors LoRaWAN RTU

The TBSL1/RFB-LoRa is a versatile outdoor RTU, acting as a multi-sensors wireless bridge leveraging the long range capability of LoRa. This is a flexible platform offering a rich connectivity for multiple usual sensors interfaces used in agricultural applications: SDI-12, pulses and analog.

TBSL1/RFB-LoRa allows connecting up to 2 SDI-12 sensors (or more with a junction box), 2 analog sensors and one pulse sensor (e.g. a rain gauge). Thanks to its large internal flash, TBSL1/RFB-LoRa can retain sensors measurements over a long period of time in case of communication outage with the server.

The platform is fully configurable: multiple types of sensors can be attached and each of them can operate on its own time basis for measurement.

The embedded LoRa modem supports both low (433/470MHz) and high (868/915MHz) LoRa radio bands, which makes TBSL1/RFB-LoRa suitable to be used anywhere without having to replace the RF board. TBSL1/RFB-LoRa is deployed as a unique node into a typical LoRaWAN network architecture, sending its packets to the gateway that relays them to the LoRaWAN server over a TCP/IP connection:

TBSL1/RFB-4G – Multi-sensors LTE RTU

The TBSL1/RFB-4G is a versatile outdoor RTU, acting as a multi-sensors wireless bridge and that can operate on any LTE or 3G network thanks to its dual mode modem.

This is a flexible platform offering a rich connectivity for multiple usual sensors interfaces used in agricultural applications: SDI-12, pulses and analog.

TBSL1/RFB-4G allows connecting up to 2 SDI-12 sensors (or more with a junction box), 2 analog sensors and one pulse sensor (e.g. a rain gauge). Thanks to its large internal flash, TBSL1/RFB-4G can retain sensors measurements over a long period of time in case of communication outage with the server. The platform is fully configurable: multiple types of sensors can be attached and each of them can operate on its own time basis for measurement.

TBSL1/RFB-4G relies on MQTT protocol to exchange data with the application server, which ensures a robust transmission and guarantees a quality of service. Upon transmission interval the platform establishes a (secure) TCP/IP connection with the MQTT broker and publishes its measurements. At the same time the platform reacts to potential configuration messages it subscribed to or to firmware over the air update (FOTA) procedure.
