The reliable operation of modern public security monitoring systems depends on addressing environmental and electrical risks effectively. Implementing robust protective measures is essential to prevent damage and ensure the longevity of these systems in the face of external challenges.
With the rapid development of public security monitoring systems in various places, the use of high-tech defense means to ensure people’s safety has become more and more deeply rooted in people’s lives. The stability and safety of monitoring system equipment are particularly important. Some irreversible factors, such as lightning strikes, induced electricity, and induced lightning damage, have greatly increased the possibility of damage. The consequence may cause the entire monitoring system to fail to operate and cause inestimable economic losses. The monitoring system is generally divided into front-end equipment, transmission part and terminal equipment.
Among them, the front-end and transmission parts are most likely to be struck by lightning, because the front-end equipment is generally placed outdoors, and many places are relatively high, or located in open areas. In some factories and mines, the possibility of being disturbed is also relatively large. Traditional wire transmission is greatly affected by the surrounding environment, but because many projects now use optical fiber transmission, the transmission line and the main control part of the equipment are generally not affected by lightning strikes, but how to take effective lightning protection measures for the front-end equipment exposed outdoors is particularly important for the stability of the entire system.

Diodes are integral components in automotive electronics, serving multiple critical functions to enhance vehicle performance and safety. One primary application is in power rectification within alternators, where diodes convert alternating current (AC) generated by the alternator into direct current (DC) to charge the battery and power the vehicle’s electrical systems. This rectification process ensures a stable and reliable power supply, which is essential for the proper functioning of various electronic components in modern vehicles.
In addition to power rectification, diodes are crucial for protecting sensitive automotive electronics from voltage spikes and surges. Transient Voltage Suppression (TVS) diodes, for instance, safeguard circuits against sudden overvoltage events that can occur due to lightning strikes or switching transients. By clamping excessive voltages, TVS diodes prevent potential damage to critical systems such as engine control units (ECUs) and infotainment modules, thereby enhancing the overall reliability and longevity of automotive electronics.
Furthermore, diodes play a significant role in automotive lighting systems, particularly with the widespread adoption of Light Emitting Diodes (LEDs) for vehicle illumination. LED drivers often incorporate diodes to manage current flow and ensure consistent brightness levels. Recent advancements include the development of synchronous buck LED drivers capable of driving longer LED chains with high efficiency, contributing to improved energy consumption and design flexibility in automotive lighting applications.

Diodes are essential components in the instrument measuring devices industry, serving various critical functions to enhance measurement accuracy and device reliability. One significant application is in temperature measurement systems, where diodes are utilized as temperature sensors. The forward voltage drop across a diode varies predictably with temperature, allowing precise temperature monitoring in electronic instruments. This characteristic enables the development of diode-based temperature measurement devices that are both simple and accurate, with resolutions up to 1 °C and accuracies within ±2 °C.
In optical measurement instruments, photodiodes play a pivotal role by converting light into electrical signals. They are extensively used in applications requiring the detection and measurement of light intensity, such as spectrophotometers and optical power meters. Photodiodes offer high sensitivity and rapid response times, making them ideal for precise light measurements across various scientific and industrial applications.
Furthermore, laser diodes are employed in displacement measurement devices, providing high-accuracy distance and position measurements. Laser displacement sensors, which incorporate laser diodes, are capable of measuring microscopic dimensions, including wafer thickness and substrate height. These sensors are utilized in a wide range of applications, such as inspecting brake disc displacement and engine vibration in automotive contexts, underscoring the versatility and importance of diodes in precision measurement instruments.
