Introduction

OVP-24G is a comprehensive optical-electrical conversion device with optical fiber switch capability, and it can complete the transmission, reception, and 3D scatter switching of optical fibers. It is widely used in digital optical communication systems, which can be used in various access control systems to increase the detection rate, accuracy, and system reliability of the system.

Application field

The OVP-24G mainly used for access control systems, such as legal access control, military access control purpose, public security or traffic system. It is suitable for large-scale network access control systems such as airports, ports, and large venues such as stadiums, but also for small individual access control needs. Compared to the traditional access control system, the detection rate and accuracy of the OVP-24G are improved. In addition, the OVP-24G not only has a simple installation and maintenance process, but also has strong expandability, which can meet the requirements of large-scale access control system expansion.

Working Principle

The OVP-24G mainly based on linear optical-electrical conversion technology to achieve high-speed optical signal conversion.The OVP-24G is a linear optical-electrical converter based on the Binary 12-level Amplitude Modulation method. The optical signal is converted into a corresponding electrical signal by the optical receiver, and then restored to the level of the 12-level signal which was initially modulated by the 12-level de-emphasis circuit, and then sent out by the optical transmitter after amplifying the level. The system has a serial port, the module will send out the corresponding signal when the valid card is read out via the serial port. The corresponding signal is transmitted to the host computer via the serial port to control the latch of the host computer, and then the system performs the unlocking action. The optical signals received by the OVP-24G boards are converted into electrical signals, and then the signals are judged by the corresponding programs to determine whether the card is valid. When a valid card is detected, the relay is output and the door is unlocked.

Conclusion

With the continuous improvement of security needs, the application of OVP-24G is increasingly wide. The OVP-24G has the characteristics of high detection accuracy, fast recognition speed, and simple installation and maintenance, which can solve the needs of digital access control system projects with high reliability. In addition, OVP-24G can be used to control high voltage devices for remote control purposes. It is an excellent choice for customers to buy.
