Its normally open circuit is closed when an object is detected approaching, and controls the relay 4 to turn on the radar host 5, otherwise it controls the relay 4 to turn off the radar host 5. The radar host 5 is connected to the circuit between the relay 4 and the detection radar 6, and is used to control the opening and closing of the detection radar 6, and convert the analog signal detected by the detection radar 6 into a digital signal to calculate the distance of the obstacle and determine whether the alarm threshold is reached; the detection radar 6 is installed near the fire protection facility box door 11, and is used to transmit radio waves and receive reflected waves; the buzzer 8 is installed near the fire protection facility box door 11, and is used to receive the alarm signal of the radar host 5 and buzz the alarm.

[0027] Working principle: After the system is powered on, it enters the standby state. Once the proximity switch 7 senses that an object (such as an appliance, logistics equipment vehicle, etc.) is approaching or blocking the fire protection facility door 11, the normally open circuit built into the proximity switch 7 is immediately closed, activating the relay 4, so that the radar host 5 obtains power supply. Subsequently, the detection radar 6 starts to work, accurately measures the distance between the obstacle and the detection radar 6, and transmits these real-time data to the radar host 5. The radar host 5 analyzes these distance signals according to the preset alarm logic. Once it is determined that the obstacle poses a risk of blocking the fire protection facility, the alarm mechanism is immediately activated to control the buzzer 8 to alarm.

[0028] Take a real-life scenario as an example. An employee accidentally pushed a logistic device in front of a fire-fighting facility, blocking the door of the fire hydrant box. The automatic detection system immediately sensed the blockage and triggered an alarm. Although the employee was surprised at first, he quickly realized his mistake and moved the device away under the clear prompts of the buzzer 8. This process not only effectively avoided the risk of fire-fighting facilities being blocked, but also educated employees through real cases, improved their awareness of compliance with fire safety regulations, and further consolidated the fire safety line of defense.

Any technician familiar with the technical field can easily think of changes or substitutions within the technical scope disclosed by the present invention, which should be included in the protection scope of the present invention.
