TDE series Seismic Data Acquisition Systems

　　TDE series seismic data acquisition systems (TDE-224C/324C/324F/324CQ/324CI types) convert the analog signals that the seismograph output into the digital signals, and output the signals with the serial ports. These systems adopt design patterns of high integration, feature wider range of dynamic response, lower power consumption and the stable reliability. The systems also provide the calibrated signals including step signals, sine waves, pseudo-random signals, simulated seismic signals for the seismometer. TDE series systems have the monitoring channel that is used to monitor environmental conditions, including environmental parameters such as supply voltage, voltage of the storage battery, and temperatures.

　　TDE-324C seismic data acquisition system has passed the test by the CEPREI（China Electronic Product Reliability and Environmental Testing Research Institute）in July 2000, the test report NO. is YW00372.

　　TDE-324CI seismic data acquisition recorder is designed in compliance with the technical specifications of the Tenth Five-year Program worked out by the China Earthquake Administration, and by considering feedback information from domestic users, drawing lessons and assimilating experience. It is my company new generation seismic data acquisition recorder of independent development. It follows the latest international trends in electronics design. The newly released state-of-the-art CS537x series 24 bits AD chip, some high performance and low power consumption RISC processor/DSP devices are used.It is also installed with a high reliable real time operating system (RTOS) that is FAA Safety Certified, which is widely used in airplane and spacecraft.

TDPP series Power Supply Controllers

　　TDPP series power supply controllers include TDPP2-400,TDPP-150,TDPP-300,TDPP-150A types controllers。TDPP2-400 power supply controller is used with "Solar Cell + 220VAC + Storage Battery" power supply mode，TDPP-150/150A/300 power supply controller is used with "220VAC + Storage Battery" power supply mode.

　　its input voltage scope is ±30%. They can output steady volts d.c.（AC-DC）, as well as can output steady volts a.c.（DC-AC，it configures TDI-150 inverter）. When the city power supply failure, it can switch to the storage battery power supply. It can charge automatically the storage battery online, can monitor automatically the storage battery voltage at the same time and control the storage battery not to overcharge and overspend.

TDD-0832 Multiport Serial Adapter

　　TDD-0832 multiport serial adapter is reachered and producted especially by our company, it can drive single-port input into multiport output.

TDH-25 Data Marshalling Indicator

　　TDH-25 data marshalling indicator is a multi-route transporting data monitor reachered and producted by our company. It is applied in ADAPT Regional Digital Telemetry Seismic Network System and SMART Digital Strong Motion Observation Processing System to monitor the data transporting status of every seismic observation station. Want to know more about it, please download "TDH-25 Data Marshalling Indicator Manual".

TDS Single Digital Seismic Data Processing System

　　TDS single digital seismic data processing system is used in many civil engineering applications. TDS system has already passed and obtain the authentication of the Science and Technology Department and the Seismic Bureau of Guangdong Province in July 1998. This system has the international advanced level.

Adapt Regional Digital Telemetry Seismic Network System

　　Adapt regional digital telemetry seismic network system is a set of current digital seismic data acquisition and processing system. It can record the real-time seismic motion signals, detect fast, identify and position the earthquake affairs, and give an alarm, create automatically the seismic data monthly report etc.. Adapt system adopt Windows NT operating system, can accept the seismic datas from 4 to 128 routes. To ensure the data reliability of the seismic network center system it use double backup processing systems. Two sets of processing systems are complete independent, even one breaks down, the other will work continuously.

Seismic Data IP Transmission & Staroge Unit(ITU)

　　Seismic data IP transmission & staroge unit (ITU) is the important device of IP transporting solution to the seismic station. It is designed in compliance with the technical specifications of the Tenth Five-year Program worked out by the China Earthquake Administration. It changes the seismic datas of the seismic station into IP data stream, compresses the datas with the revised SEED-STEIM2 compression calculating way, and sends the seismic datas to the data processing units by internet network. In addition, ITU also can store the on-line datas and support data retransmission at breaking point.
