INTRODUCTION:
The special encoder/decoder for petroleum seismic exploration is used to accurately control the time synchronization between the recording system of instrument truck and detonation. Generally, instrument truck is often several kilometers to more than ten kilometers away from the detonator so that detonation should be controlled through wireless communication as well as to achieve simultaneous sampling and recording. The wireless synchronization trigger developed by our company is based on the function of petroleum wireless triggering blaster but its design has been improved accordingly. It not only can remotely control the detonation but also has additional functions such as ignition control via spark sources and wireless trigger via hammering sources. Its synchronization error is less than 20us and the maximum wireless trigger distance is up to 10KM. It supports various types of seismographs at home and abroad.
APPLICATIONS:
- Multi-band wireless walky-talky communication
- Safe and precise remote detonation
- Wireless synchronization triggering between two tunnels
- Wireless synchronization triggering between the two sides of the river
- Other cases not suitable for wired triggering
FEATURES:
- Small, lightweight, low power consumption.
- Long trigger distance, up to 10KM or more.
- Synchronization error < 20us.
- Matches various seismic sources and seismographs and can be used to detonate detonators.
- Provided with a computer interface, easy to use.
TECHNICAL SPECIFICATIONS:
1. Transmission distance
Its transmitting and receiving distance is over 10 kilometers when used in straight line transmission (without obstacles);
Its communication distance can reach more than 5 kilometers in places where there are more buildings and signal interference such as inland areas and cities;
Its communication distance is more than 2 kilometers in places where buildings are dense and the signal is attenuated the most.
2. Frequency range
Full coverage of four bands. V1 ~ V4 range: 136-174 MHz. The frequency range of each communication channel is programmable. It features wide frequency range and strong adaptability.
3. Power
The maximum power of radio: ≤ 54W; 54W in high-grade, 20W in low-grade.
4. Trigger
Wireless trigger distance >5KM
Synchronization error: <20us
Provides multiple wireless triggering modes: Explosive initiation mode, sparker ignition mode, Hammer triggering mode, etc.
Supports relay mode. The use of wireless trigger can allow a greater distance and solve the triggering problem between tunnels at the same time
