How does the Dual Head Emergency Light perform power supply detection?

Power supply detection is the first and most critical step in the work of the Dual Head Emergency Light. It is directly related to whether the emergency light can respond quickly and start the emergency lighting when the main power supply is interrupted. Therefore, an efficient and accurate power supply detection mechanism is crucial to the performance of the emergency light.

The power supply detection of the Dual Head Emergency Light is mainly realized through the built-in detection circuit, which usually includes a voltage detection module, a signal processing module, and a control logic module.

The voltage detection module is the core part of the power supply detection, which is responsible for real-time monitoring of the voltage of the main power supply. The voltage detection module converts the voltage value of the main power supply into an electrical signal through a high-precision voltage sensor and transmits it to the signal processing module. After receiving the electrical signal from the voltage detection module, the signal processing module will amplify and filter it to improve the accuracy and stability of the signal. At the same time, the module will also compare the processed signal with the preset threshold to determine whether the main power supply is in a normal state. When the signal processing module determines that the main power supply is abnormal (such as low voltage, interruption, etc.), it will send a signal to the control logic module. The control logic module responds quickly based on the received signal and starts the emergency lighting program. At this time, the Dual Head Emergency Light will disconnect from the main power supply and activate the battery power supply circuit to light up the dual head light head.

In order to ensure the accuracy of power supply detection, the Dual Head Emergency Light adopts a variety of technical means in its design.
High-precision sensor: Use high-precision voltage sensor to ensure the accuracy of voltage detection.
Intelligent algorithm: Combine intelligent algorithm to process and analyze the signal to improve the accuracy and stability of judgment.
Multiple protection: Set up multiple protection mechanisms, such as overvoltage protection, undervoltage protection, etc., to ensure the safety and reliability of the power supply detection circuit.

The power supply detection mechanism of Dual Head Emergency Light is the basis for its efficient and stable operation. Through the comprehensive use of high-precision sensors, intelligent algorithms and multiple protection mechanisms, the emergency light can accurately monitor the status of the main power supply and quickly start emergency lighting in an emergency. This accurate and reliable power supply detection mechanism provides a strong guarantee for people's life safety, and also reflects the outstanding achievements of modern technology in the field of emergency lighting.
