The emergency escape prewarning indication system of the passenger ship is composed of information system terminal nodes 1 on the ship, a system power supply module 2, an information transmitting and receiving module 3, an information analysis module 4, a prewarning indication module 5, and a ship CAN bus 6. The information system terminal nodes 1 include a fire fighting system terminal node, a monitoring system terminal node, a flooding detection system terminal node, and an inclination angle measurement system terminal node, and are used to transmit danger data information detected by all information systems to the ship CAN bus 6. The ship

The CAN bus transmitting and receiving circuit is connected to the transmitting and receiving end of the ship CAN bus 6. The power input end of the information transmitting and receiving module 3 is connected to the system power supply module 2 and is used to supply electric energy to the whole information transmitting and receiving module 3; the transmitting and receiving end is connected to the ship CAN bus 6 and is used to receive node data on the ship CAN bus 6 in real time, transmit the node data to the information receiving equipment by means of a CAN bus transmitting and receiving circuit for summarization, then transmit the node data to a central controller in the information analysis module 4; the serial data end is used to output the processed node data; the data input/output end of the information analysis module 4 is connected to the serial data end of the information transmitting and receiving module 3 and is used to receive the summarized node data of all the passages, analyze and process the states of the nodes of all the current passages, and send instruction information by means of the CAN bus transmitting and receiving circuit in the information transmitting and receiving module 3 by means of a serial-port based protocol; and the prewarning indication module 5 is connected to the transmitting and receiving end of the ship CAN bus 6 and is used to receive the instruction information forwarded by the information transmitting and receiving module 3 and sent from the information analysis module 4. The ship CAN bus 6 is at least connected with one intelligent emergency indicator lamp terminal node.
[25] As shown in FIG. 2, a specific work flow of the embodiments of the present invention is as follows:
[26] in first step, in case of an accident, electric signal danger data information detected by a fire fighting system, a monitoring system, a flooding detection system, and an inclination angle measurement system on the ship are concentrated and are sent to the ship CAN bus 6 by means of all the information system terminal nodes 1;
[27] in second step, the information transmitting and receiving module 3 extracts the related danger data information on the ship CAN bus 6 and transmits same to the information receiving equipment by means of the CAN bus transmitting and receiving circuit for summarizing;
[28] in third step, the electric signal danger data information received by the information receiving equipment is transmitted to the central controller; the central controller extracts, analyzes, and determines the information; firstly, whether a passage is safe 1s determined according to whether there is smog or flooding in the passage, and an unsafe passage is defined as a "dangerous passage";
[29] in fourth step, the central controller continues to analyze and determine the data in the remaining passages except for the "dangerous passage", and determine a jam degree in the passage according to the number of personnel in the passage and a moving speed; a passage with a relatively large jam degree is defined as a "jammed passage", and an unobstructed passage with a relatively small jam degree is defined as a "green passage"; at the end of determination, the central controller transmits type information of the definition of the determined passage to the information transmitting and receiving module 3;
[30] in fifth step, at the end of determination, the central controller stores and summarizes the type information of the definition of the determined passage, analyzes and connects all the green passages (or jammed passages) to form a route that can help on-board persons to leave a dangerous area, i.e., a safe route that helps the on-board persons to escape, and transmits the route to the information transmitting and receiving module 3; the central controller can control all the intelligent emergency indicator lamps in a linkage manner to enable the lamps to work alone; and
[31] in sixth step, the ship CAN bus 6 transmits the related information to the related node of the intelligent emergency indicator lamp in the passage corresponding to the prewarning display module 5. After receiving the type information of the passage, the emergency indicator lamp automatically realizes corresponding displaying and voice prompt. All the routes that are formed by connecting the green passages (or jammed passages) and help the on-board persons to leave the dangerous area are the safe escape routes supplied in the present invention to the on-board persons.
[32] In addition, when the passages in the designed safe escape routes are in danger, or when the danger in the dangerous passage is relieved, the system can quickly remake a safe escape route in time according to feedback information of all the information systems on the ship.
[33] FIG. 3 illustrates a work flow diagram of the intelligent emergency indicator lamp. In case of a danger in the passenger ship, the central processor extracts and analyzes the passage classification information forwarded by the ship CAN bus 6 and sent from the information analysis module 4 to determine an indicated type of the indicator lamp. A digital signal is converted into an electrical signal through the D/A converter and transmitted to the LED display screen and the loudspeaker; the LED display screen is controlled to display a corresponding indication signal, and the loudspeaker is controlled to make a voice prompt, so as to reflect the safety and jam in the passage where it is located.
[34] FIG. 4 illustrates a relevant standard of graded indication of the emergency indicator lamp. Escape direction indication: the LED display screens are automatically arranged into a green arrow and flicker, and a voice prompt is made: "Please follow the indication arrow to escape". Jam degree indication: the LED display screens are automatically arranged into a yellow warning mark and flicker, and a voice prompt is made: "Passage is jammed". Danger warning indication: the LED display screens are automatically arranged into a red prohibition icon, and a voice prompt is made: "Passage is dangerous". All the escape indications can be used alone or in a combined manner.
For the passages classified to the safe escape route, the green passages are only for indicating the escape direction, and the jammed passages indicate both the escape direction and the jam degree. The passages that are not classified to the safe escape route indicate the escape direction and danger warning in a unified way. The intelligent emergency indicator lamp can clearly point out a correct and safe escape route for passengers at a critical moment by means of flickering light signs and voice prompts.
[35] FIG. 5 illustrates a specific implementation case of the emergency escape prewarning indication system of the passenger ship on a certain floor of a medium-sized passenger ship. If the passenger ship is in an overturning danger since it tilts towards the left side, it is analyzed that: since the starboard of the passenger ship is relatively far from the water surface, a person who jumps overboard and escapes will hit the ship body easily, which causes secondary injury to the human body.
Therefore, all the passages 11 on the right side of the ship body are not suitable for escaping and are displayed in a red prohibition sign.
For the passages on the left side of the ship body, since the passage 7 onthe left side of the stern is on fire or flooded, this passage is a dangerous passage, and the intelligent emergency indicator lamp is displayed into a red prohibition sign.
The passage 9 on the left side of the prow has personnel congestion, and the intelligent emergency indicator lamp is displayed into a yellow warning sign.
Only the amidship passage 8 on the left side and the central aisle 10 are unobstructed, and the intelligent emergency indicator lamps are displayed into green arrows.
Therefore, routes from the central aisle 10 to the passage 9 on the left side of the prow and the amidship passage 8 on the left side are safe escape routes, and the route from the central aisle 10 to the amidship passage 8 on the left side is the best escape route.
