Application of Explosion-proof Laser Detector in Perimeter Alarm System of Petroleum and Petrochemical

From the perspective of China’s current energy structure, oil will still be the main energy supply for a long period of time in the future. Therefore, whether the process of oil extraction, processing, transportation, and use can be safe and stable for a long time will be related to the country’s economic development. Major issues. In recent years, due to the lack of timely and reasonable monitoring and treatment, fires, explosions, and environmental pollution caused by oil and gas theft, construction damage, oil spills and pollution, illegal invasion and damage have caused immeasurable losses to people's production and life.

As a 17-year-old company focusing on the security field with ingenuity and quality, Guangzhou Ailifu Electronic Technology Co., Ltd., its high-end brand "Vidas", launched the fifth generation-intrinsically safe explosion-proof laser beam detection based on market demand. Used for intrusion prevention alarm system in the perimeter of petroleum and petrochemical industry. The intrinsically safe explosion-proof laser perimeter intrusion prevention system is to ensure the personal and property safety in the guarded area of ​​the petroleum and petrochemical site. Through the installation of Viandas intrinsically safe laser beam detectors around its walls, day and night vigilance is carried out. When an alarm is detected, the switch signal from the receiving end of the laser intrinsically safe explosion-proof laser intrusion detector is transmitted to the large communication alarm host of the management center. The alarm host will accurately display the location of the alarm and prompt the security personnel to quickly confirm the alarm and rush to the scene in time to ensure the personal and property safety of the residents.

working principle:

The intrinsically safe explosion-proof laser intrusion detector belongs to the active intrusion detector category, which consists of a laser transmitter and a laser receiver. The laser transmitter is composed of a laser transmitter, a modulated excitation power supply and a corresponding direction adjustment device; the laser receiver is composed of a laser receiver, a photoelectric signal processor and a corresponding support mechanism. The laser transmitter emits a directional strong laser beam with good directivity, single frequency and consistent phase, which is unmatched by other light sources. The laser intrusion prevention system uses invisible modulated laser beams (single beam or multiple beams) to form a warning line, and uses a shielding alarm method to close the perimeter, plane and three-dimensional space for defense.

Technical features:

1. Intrinsically safe explosion-proof design, no need to add an explosion-proof box, explosion-proof mark: ExiaIICT6Ga, suitable for other explosive gas environments except coal mine gas, with a high (Ga) explosion-proof protection level.

2. Precise voltage stabilization and micro power consumption design, dual overvoltage and overcurrent protection, guarantee from the source that the detector will not produce high temperature or sparks under various conditions.

3. It adopts high-quality DC solid-state relay output, which has excellent performance such as high output strength, impact resistance and strong shock resistance. It can be directly connected to the computer terminal digital control circuit.

4. Invisible laser is preferably used as the detection light source + large-scale MCU precise modulation, which can easily penetrate various environmental interferences such as wind, frost, rain, snow, fog, sand and dust.

5. Multi-layer precision coating narrow-band filter lens + integrated digital receiving amplification filtering and shaping, effectively filtering out various interference light sources in the environment, and accurately controlling the detector to avoid false alarms and false alarms.

6. Intelligent recognition of beam identity, each beam is coded and decoded independently, and each beam can be accurately identified at any distance between the transmitter and the receiver, and will not form the mutual coverage and interference of the beams, and will not cause false alarms and false alarms (Patent No.: ZL201821802327.0).

7. Two working modes of debugging/detection (patent number: ZL201920598411.3): in debugging mode, with the visual laser debugger (patent number ZL201821490714.5), precise alignment of each beam can be quickly achieved.

8. Single/double/three/four beam interruption alarms are optional (patent number: ZL201320115616.4).

9. Space capsule-style anti-electromagnetic damage design: 304 stainless steel shell + internal high-strength, high-insulation composite material bracket to protect the internal laser of the detector from external electromagnetic signals and static electricity.

10. The trigger time can be selected in multiple levels and can also be customized to meet different purposes in different places.

11. The receiver indicates the independent working status of each beam, and the working status of each beam is clear at a glance.

12. Pass the CLASS1 safety laser certification, which will not cause pollution and harm to the environment and human body.

13. Water-proof, dust-proof, insect-proof and demolition-proof, the protection level can reach IP67.
