Viandas Network Laser Penetration Intrusion Detector is a front-end detector used in perimeter anti-theft alarm system. It has long detection distance, high sensitivity, low false alarm rate, good safety, reliability, concealment, and convenient maintenance and debugging. Adapt to various adverse natural climate conditions and other advantages.
A laser transmitter is set at the beginning of the protection area, and the directional strong laser beam emitted by it is directed to the receiving end. At the receiver, the received optical signal is converted into a digital signal by a photoelectric device and processed by the discriminator. When the confirmation signal is normal, a green light is displayed internally to maintain the monitoring state; when the light beam is interrupted, the signal is abnormal, and a red light is displayed internally, and an alarm signal is output at the same time. In this way, the entire distance covered by the laser beam can be monitored.
Working principle and composition:
The laser beam detector consists of two parts: receiving and sending.
The laser transmitter emits a laser line to a receiver installed hundreds of meters or even several kilometers away, and its beams are single, double, or even multiple beams. When the corresponding laser beam is blocked, the receiver sends out an alarm signal. The receiver is composed of an optical lens, a laser phototube amplification and shaping circuit, a power driver, and a laser beam shooting mechanism.
Its working principle is that the receiver can receive the laser beam in a normal state, and when an intrusion occurs, the laser beam emitted by the transmitter is blocked, that is, the photocell cannot receive the laser light source, thus outputting the corresponding alarm electrical signal, and After shaping and amplifying, it outputs switching alarm signal. This alarm signal can be received by the alarm controller, and it can be linked to the actuator to start other alarm equipment, such as alarm host, sound and light alarm, analog electronic map, monitoring system, lighting system, etc.
Among the brands of network-based laser intrusion detectors, the brand “Viandas†of Guangzhou Aifu Electronics has always had a good reputation in the field of security, and it has been updated to the fifth generation of intelligent laser beaming, making it more It is smart and applicable to a wider range of fields. The beam spacing, the number of beams, and the detection distance can be customized according to customer needs.
Performance characteristics:
1. Selected high-quality 304 stainless steel shell, resistant to external force damage and adverse climate effects;
2. Adopt 980nm invisible laser as the detector light source, invisible prevention, super stability;
3. Single / double / three / four beam interruption alarms are optional, suitable for various environmental applications;
4. The X / Y axis angle of each beam can be adjusted independently, which can be widely used in places with high and low drop;
5. Adopt high-brightness blue LED light group as alignment instruction, easy and quick installation and debugging;
6. Built-in IP network communication module, the alarm signal adopts network transmission, and the system works more stable;
7. The detection distance is super far, and the farthest can reach 5000 meters;
8. Designed according to the requirements of military grade, suitable for the harsh environment of -55 ℃ ～ 70 ℃;
The network-based laser intrusion detector system developed by Guangzhou Ailifu Electronics "Viandas" is stable, reliable and highly sensitive. The whole is made of steel and aluminum. The mechanical structure of the system is precise, the laser system and optical components are processed by precision instruments, and the internal structure is stable. The system installation is comprehensive, firm and reliable. Long service life and low maintenance cost. Making full use of the characteristics of the laser system can reduce the cost of purchasing equipment, reduce the amount of construction and the impact on the environment. The replacement of the laser tube is very convenient and the maintenance cost is low.
Cnc Turning
CNC turning is a subtractive manufacturing process in which pieces of material are rotated as a machine tool is fed to the piece, removing material to create a finished piece. It is primarily used to manufacture parts that are cylindrical in nature. We supply custom cnc turning service and CNC turning parts manufacturing
What is CNC TURNING?
Items processed by a lathe will be cylindrical and must be on-centre. Turned parts can range from simple rings to complex curved components. CNC turning is the most efficient way to mass-produce these kinds of parts.
Various cutting tools can be installed within the lathe tooling head to perform different cutting operations sequentially, to produce parts in a one-pass process. Straight cuts, tapers and contours can all be created by varying the angle and depth of the cut.
RongNa CNC Turning system is capable of cutting and holding different types of materials with complete accuracy and efficiency. CNC Turning to manufacture anything from furniture to garden tools to intricate machines and parts for cars and trucks etc.
We are professional CNC Turning Service company and custom CNC Turning Parts manufacturers in China, Our CNC Turning Center help with all kinds of projects and makes cuts of any work piece by changing the angle, the material and the type of cutting tool being used.
