GPRS DTU wireless data transmission with new solutions

Kb3000 GPRS DTU KB3000 GPRS DTU (Data Terminal Unit) is the use of high reliability ARM7 processor and GPRS wireless data transmission terminal transparent. Based on public data transmission network with a wide range of communication, transmission is stable, and reliable, KB3000 GPRS DTU in the field of unmanned, remote equipment monitoring, remote data acquisition, remote meter reading and remote scheduling has been widely used. Because this product is designed for industrial integration, in terms of the temperature range, vibration, electromagnetic compatibility and interface diversity are uniquely designed to ensure job stability in harsh environments, the data communications equipment to provide your high quality assurance. Provide different customized terminal user requirements for different industries, which requires a combination of industry-specific hardware, software development and systems integration. GPRS mobile data network channel can provide TCP / IP connection, it can be used to connect INTERNET, data transmission applications. The KB3000 GPRS DTU (Data Terminal Unit) data terminal unit, is designed for serial data transfer via GPRS mobile data network GPRS wireless devices. This product is for power system automation, industrial monitoring applications, traffic management, meteorology, environmental protection, network monitoring, finance, securities and other sectors, taking into account aspects of networking requirements of each application sectors, virtual private network data over the network structure . Centre for multi-point, multi-point transmission scattered small amount of data. ? 2 Product Features Standard industrial products, EMC anti-jamming design, the ability to adapt to the environment;? Independent research and development, 32 ARM7- CPU with embedded real-time operating system;? Watchdog embedded chip, offers a variety of reset mechanism, can software control to achieve the perfect industrial protection mechanism. ? Advanced and strict data communication protocol, comes with error correction and encryption. Data transmission never loss, can transmit more than 100K of pictures and Flash animation files will not appear mosaic; multiple operating modes:? DTU, Modem, SMS Modem three operating modes, when Modem is set to use, compatible with standard AT commands (GSM07.05 and 07.07), SMS Modem operating mode, the user can set SMS transmission with protocol and without agreement; supports multiple data transmission protocols:? routine, compatible and transparent optional three protocols . When used in conjunction with KB2000-A allows users before software and the device does not make any changes, you can achieve Internet-based application system; automatic network supports a variety of ways: with serial - network switches networking product KB2000, KB3000 also? (no Internet using GPRS convenient conditions) can be used with the same type of product KB3000 network, enabling one to one, one to many networking; Plug and Play feature:? When the Company or KB3000 KB2000 own network, this When no software and hardware development, to build large-scale SCADA systems; IP auto-enrollment mechanism, you can achieve a variety of service models, building a complete ultra-large-scale wireless applications; remote hibernate and wake up:?? can dial phone numbers specified DTU DTU number or send a text message to be dormant and awakened, user-friendly in that it hibernate when not in use saves DTU traffic charges; remotely modify the DTU parameters:? Support SMS DTU modify parameters, as well as modify the DTU network parameters; IO switch function? : a two-way switch inputs, one switching output. It can be read via the remote control. You can set the alarm threshold state, and set the alarm if the automatic reporting alarm function; powerful communication standby function:? Support connected to the main server and backup server automatically switch to support TCP, UDP communications automatically. Once the primary server problems, automatically connect to the backup server, if the TCP connection is not automatically communicate using UDP;? Powerful server software support, the server software for many years, powerful and sophisticated;? Support private APN, the data center Supports fixed IP and dynamic DNS; Industrial temperature range:? Working temperature: -40 ℃ -80 ℃, at -40 ℃ when communication is not affected. 3 Safe Use KB3000 GPRS DTU full compliance with the technical regulations on radio products, but please note: Do not hand or other body parts touch the antenna, in the beginning turned 15 seconds as far away from the antenna, the antenna should be replaced if damaged , supporting the use of qualified cables and antennas. 4 electromagnetic interference Currently, most electronic devices have taken the electromagnetic protection measures, but there are also old equipment may not take appropriate protective measures, failure may occur at RF energy radiation, the use of KB3000 GPRS DTU should close within the scope of inspection The device is ready electromagnetic protection. 1B2 KB3000 GPRS DTU technical parameters 12B2.1 GSM / GPRS: band: EGSM900 / DCS1800 GPRS Multi-slot Class 12 GPRS Mobile Station Class B GPRS coding: CS1 ~ CS4 Output Power: Class 4 (2W) at EGSM900MHz Class 1 (1W) at DCS1800MHz sensitivity: (. typ) (. typ) 108 dBm at EGSM900 MHz 106 dBm at DCS1800MHz compatible with standard AT commands (GSM07.05 and 07.07) supports the extended instruction support SMS, USSD, CSD embedded TCP / IP protocol 13B2.2 Basic functions: Embedded TCP / IP protocol compatible with standard AT commands (GSM07.05 and 07.07) supports the extended instruction support SMS, USSD, CSD transparent data transfer support IP address or domain name data center supports dedicated APN 15B2.4 electrical data voltage RS232 When: DC 5V ~ 16V, RS485 time: DC 5V Power consumption: Standby: <30mA @ 5V Communications: <100mA @ 5V when emission peak: <1.2A@5V 16B2.5 Environmental Operating temperature -40 ℃ ~ 80 ℃ storage Temperature -45 ℃ ~ 125 ℃ Relative Humidity: 20% to 95% (non-condensing)
