[0041] The control logic of the voice alarm is as follows Figure 7 As shown, when a human body continuously approaches the voice alarm for a period greater than or equal to N seconds or stays near the voice alarm for a period greater than or equal to N seconds, the voice alarm considers that a human body is approaching the designated danger zone and starts to issue an alarm voice; conversely, when the duration of continuous approach to the voice alarm is less than or equal to N seconds, the voice alarm considers it a false operation and does not issue an alarm voice.

[0042] The time N seconds that a person stays or approaches the voice alarm continuously determines the sensitivity of the voice alarm. The value of N can be adjusted and determined by the on-site working conditions.

[0043] It also has the function of adjusting the sensing distance to suit different alarm scenarios.
