1. In the engineering design, in order to facilitate the usual maintenance and management, the fire emergency lighting is preferably powered by a dedicated feeder loop.
2. In order to ensure the reliability of the fire emergency power supply, the condition should be powered by the low voltage emergency bus section of the substation. That is, when the diesel generator set is used as the emergency power supply, as long as the generator is put into use, it will continue to guarantee the electricity. powered by.
3. In the fire state, there is less smoke and more oxygen near the ground, and the instinct response of human evacuation is bending or squatting forward, so local high illumination illumination is more effective than uniform illumination brought by high position installation. Therefore, low-level installations should be promoted, that is, evacuation emergency lighting should be provided close to the ground or at ground level.
4. The emergency lights are delivered in the discharged state, and must be charged for 20 hours before use.
5, the emergency luminaires in use should be regularly checked for performance, every half month or month through continuous switch test to check the circuit conversion and battery emergency function, and discharge to extend battery life.
6. Do the fire protection of the distribution line. When it is darkly laid, it should be laid in the non-combustion structure. The thickness of the protective layer is not less than 30mm. When wearing the metal tube, wear the fireproof coating on the outside of the steel pipe or adopt other fire prevention measures. Use fireproof cables or fire resistant cables and wires.
TOF (Time of Flight) ranging sensor is a type of sensor that measures distance by calculating the time it takes for a light signal to travel from the sensor to the target object and back. It uses laser or infrared light to emit a signal and measures the time it takes for the signal to return to the sensor. By knowing the speed of light, the sensor can accurately calculate the distance between itself and the target object.
TOF ranging sensors are commonly used in various applications such as robotics, autonomous vehicles, industrial automation, and augmented reality. They provide accurate distance measurements and can be used for object detection, collision avoidance, gesture recognition, and mapping.
Compared to other distance measurement technologies like ultrasonic sensors or infrared proximity sensors, TOF ranging sensors offer several advantages. They provide higher accuracy, faster response times, and can work in various lighting conditions. They are also capable of measuring longer distances and can be used for both indoor and outdoor applications.
Overall, TOF ranging sensors are a versatile and reliable technology for measuring distances and are widely used in many industries for a range of applications.
