Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of emergency command systems, in particular to an emergency mobile video command system with multiple working modes and a working method thereof. BACKGROUND

[0002] An emergency command system is a system in which the staff of a command department broadcasts command information to emergency evacuees through a loudspeaker or the like in an emergency. It can help people without evacuation experience to quickly establish the current escape route and survival strategy. There is now an emergency evacuation command system combined with video monitoring, in which the staff can see the real-time situation of the crowd in the escape passage, and then give more accurate commands according to the real-time situation.

[0003] Since the position of the camera is fixed, and the passing crowd is endless, if the staff speaks and commands one by one, it will be very inefficient, but the automatic broadcast method cannot make real-time adjustments according to the video monitoring state on the spot, for example, when encountering a panic crowd, the broadcast is information about survival strategies that need to be patiently listened to, but the panic emotions of the crowd will lead to low command efficiency. Therefore, it is necessary to design an emergency mobile video command system with multiple working modes and a working method thereof with high command efficiency. SUMMARY

[0009] According to the technical scheme, the working process of the behavior state confirmation module specifically comprises the following steps:

[0010] S1, starting the video shooting module to scan the personnel in the escape channel when the emergency evacuation broadcast is started, fitting the personnel action form according to the video shooting display of the personnel action form by the edge shape drawing module, and dividing the whole personnel action form into two color blocks, wherein the strip close to the arm shape represents the arm color block, and the color block close to the leg shape represents the leg color block, and the two connected form color blocks are classified as the personnel action form of a person, and the main body of the connected part is the trunk color block;

[0011] S2, comparing the relative position of the arm and leg color blocks of the emergency evacuation personnel in the escape channel with the personnel action form of the behavior state commonly used by people, if the behavior state commonly used by people is matched, the timing trigger starts timing, if the behavior state is maintained for more than a specified time, the panic degree analysis module determines that the current behavior state is in the emergency evacuation behavior state, and the behavior classification module is used for classifying the relative position of the current personnel into different behavior states;

[0012] S3, record the position of the personnel action form movement, combine the time counted by the timing trigger, calculate the amplitude and speed of the personnel display position change, and transmit the information to the panic degree analysis module. The current behavior is divided into an orderly evacuation state and a panic evacuation state by using the panic degree analysis module. The method is that if the personnel action form position change amplitude is relatively calm and slow, it is an orderly evacuation state. If the personnel action form position change amplitude is relatively fast and there is a certain range of reciprocating position change state, it is a panic evacuation state.

[0013] S4, instruct the information dynamic broadcast module according to different behavior conditions and the current behavior mode, and control the broadcast state.

[0014] According to the above technical solution, in the step S2, the behavior condition is divided according to the following states:

[0015] S2-1, if the leg color block presents a state of rapid left-right alternating offset, and periodically bends with a large amplitude, and the driving color block appears violent shaking, it is classified as a running evacuation state.

[0016] S2-2, if the leg color block presents a state of left-right alternating offset, and the trunk color block does not appear violent shaking, and the leg color block periodically bends with a small amplitude, it is classified as a walking evacuation state.

[0020] S5, when starting to broadcast the escape command, the initial state is to broadcast the escape crowd by the calming information broadcasting module;

[0021] S6, if the panic degree analysis module determines that the current state is an orderly evacuation state, the calming information broadcasting module is closed by the starting module, and the survival strategy information broadcasting module starts to broadcast;

[0022] S7, if the panic degree analysis module determines that the current state is a panic evacuation state, the calming information broadcasting module starts to broadcast by the starting module, and the proportion of the calming information broadcasting module in all broadcasting information is controlled by the playing proportion determination module.

[0023] According to the technical solution, in step S7, the method for controlling the proportion of all broadcasting information by the playing proportion determination module is that when the calming information broadcasting module starts to broadcast, the proportion of all broadcasting information is at a minimum value, then the proportion of all broadcasting information is continuously increased with the duration of the current behavior panic evacuation state, and the speed of increasing the proportion of all broadcasting information is adjusted according to the behavior state determined by the behavior classification module, wherein when the behavior classification module determines that the behavior state is a running evacuation state, the position change speed of the leg color block moving back and forth quickly is recorded; when the behavior classification module determines that the behavior state is a walking evacuation state, the position change speed of the arm color block moving back and forth quickly is recorded, and the panic degree analysis module transmits the information to the playing proportion determination module according to the speed of the above-mentioned personnel motion form moving back and forth, and corrects the proportion of all broadcasting information types.

[0024] According to the technical solution, the proportion of the calming information broadcasting module in all broadcasting information when the behavior state is a running evacuation state is

[0025] P=P0+e1f1t1, P≤P2

[0026] Wherein P is the proportion of the calming information broadcasting in all broadcasting information, f1 is the average leg color block position moving back and forth speed of the evacuation personnel in the monitoring video, P0 is the initial proportion of all broadcasting information, e1 is the change parameter of the proportion of all broadcasting information set when the running evacuation state, which is a constant according to experience, t1 is the time of the leg color block position moving back and forth quickly, and P2 is the maximum proportion of all broadcasting information;

[0027] The proportion of the calming information broadcasting module in all broadcasting information when the behavior state is a walking evacuation state is
