The invention is characterized in that a human body detector is arranged near the entrance of each evacuation channel on one side of the building passageway, when a person passes through the evacuation channel, the processor controls the voice broadcaster to send voice prompt information according to the judgment result, and the content of the voice prompt information reminds people to pay attention to the position as the entrance of the evacuation channel.
In order to avoid frequent reminding when a plurality of people pass through the population evacuation channel, the human body detection signals need to be counted, the voice broadcaster is controlled to carry out voice broadcast only by the processor according with the judgment condition, and the voice broadcaster is not broadcast if the judgment condition is not met. The specific statistical and judgment process is that if the current human body detection signal C isiSignal C corresponding to previous human body detectioni-1The time interval between every two adjacent persons is larger than a set value, which indicates that the persons passing through the evacuation channel entrance cannot know that the time interval between the persons passing through the evacuation channel entrance is longer, and voice broadcasting is carried out at the moment; if the current human body detection signal CiAnd the previous human body detection signal Ci-1The time interval between the two persons is smaller than the set value, which shows that the time interval between the two persons passing through the entrance of the evacuation passageway is shorter, then the calculation is carried out when the time interval is shorterPrevious human body detection signal CiWith the previous human detection signal Ci-2Time interval therebetween, and detecting the signal C for the human bodyi-2No prompt is given, if the signal is still less than the set value, the current human body detection signal C is calculated againiWith the previous human detection signal Ci-3The time interval between the two, until the human detection signal C which is the earliest to be prompted in the round of calculation is foundi-nIf the current human body detection signal CiWith the previous human detection signal Ci-nThe time interval between the two signals is greater than the set value, then the current human body detection signal C is indicatediThe time interval between the current human body detection signal C and the human body detection signal which is prompted in the last calculation is longer, and the current human body detection signal C can be detectediAnd carrying out voice broadcasting. For example, during the working hours in the morning and the working hours in the evening, a lot of people pass through the entrance of the evacuation channel, the frequency of the human body detection signal is generated, and the frequent broadcasting is not needed at the moment.
The invention realizes the automatic detection and the automatic judgment of voice broadcast of the personnel passing through the entrance of the evacuation channel, thereby improving the grasping degree and the attention degree of people to the evacuation channel through continuous automatic prompt and further improving the evacuation efficiency of the personnel when fire occurs.
Preferably, in the fire safety evacuation indication system, if the current human body detection signal C is detectediWith the previous human detection signal Ci-nThe time interval between the two is less than the set value, and the processor detects the signal C according to the human bodyi-nControlling the voice broadcaster to play prompt information, and the processor does not detect the signal C according to the current human body detection signaliAnd controlling the voice broadcaster to broadcast prompt information, wherein the value of n is a natural number which is more than or equal to 4.
If the current human body detection signal CiWith the previous human detection signal Ci-nThe time interval between the two is less than the set value, and the processor detects the signal C according to the human bodyi-nControlling the voice broadcaster to play overIndication information, which indicates the current human detection signal CiThe time interval between the current human body detection signal C and the human body detection signal which is prompted for the last time is short, and the current human body detection signal C is not requirediPrompting again, the processor does not detect the signal C according to the current human bodyiAnd controlling the voice broadcaster to broadcast prompt information.
Preferably, the fire safety evacuation indication system further comprises a client, the client runs on a smart phone, and a safety evacuation schematic diagram of a building is arranged in the client.

Preferably, in the fire safety evacuation indication system, an entrance guard device is disposed at a gate position of the building, and the client is configured to download the safety evacuation schematic diagram of the building from the entrance guard device under the condition that the client establishes communication with the entrance guard device.
When a user enters a building, the user can brush the access control device by a mobile phone and communicate with the access control device through the client to obtain a safe evacuation schematic diagram of the building. In some cases, the user enters an unaccessed building and does not pay attention to the schematic safety evacuation diagram. However, in the design, the user needs to perform access control operation, and then the safe evacuation schematic diagram of the building is directly downloaded to the mobile phone of the user, so that the user is reminded to know the safe evacuation schematic diagram, and the grasping degree of the user on the evacuation channel is further improved.
Preferably, in the fire safety evacuation indication system, the access control device includes an NFC card reader, the smart phone is a smart phone with an NFC chip built therein, and the client establishes communication with the access control device when the smart phone establishes communication with the access control device through the NFC chip and the NFC card reader.

Preferably, in the fire safety evacuation indication system, the content of the prompt message further includes an evacuation route from the current location to the building exit and an evacuation time.
In order to further improve the user's understanding and mastery of the situation of the evacuation passageway, the prompt information further includes an evacuation route and an evacuation time from the current location to the building exit. For example, the current position is 3 stories, the content of the prompt message comprises that the evacuation route from the 3 stories of the current position to the safe exit of the building is to travel all the way down to the 1-story lobby along the evacuation channel, and the evacuation time is 30 seconds.
Preferably, in the fire safety evacuation indication system, the human body detector is disposed on a wall of the building passageway and is disposed near the ground of the building passageway.
If the position of the human body detector is too high, the human body may not be accurately detected. Therefore, the human body detector is disposed at a position close to the ground to improve the accuracy of human body detection.
