The invention provides an accident warning system, which is suitable for an automatic warning of a sudden accident when a locomotive rider rides a locomotive. 1 is a functional block diagram of an accident warning system according to a first embodiment of the present invention. The accident warning system 100 includes a line recorder 110, a mobile device 120, an emergency rescue unit 170, and a traffic management server 180. The accident warning method of the present invention comprises a driving recorder 110 having a gravity sensor 115, a mobile device (for example, a smart phone) 120 carried by a locomotive knight, and an emergency ambulance unit 170 providing an emergency medical rescue for a locomotive knight. The traffic management server 180, which stores the location information of the traffic lights and performs the traffic information management, is implemented by the Bluetooth communication technology. The wireless connection between the mobile device 120 and the driving recorder 110 is a Bluetooth transmission technology.

The driving recorder 110 is disposed on the locomotive to continuously capture the driving condition of the locomotive rider when riding the locomotive. The gravity sensor 115 is disposed in the driving recorder 110 for detecting the degree of dumping and the degree of collision of the locomotive. The mobile device 110 includes a processing unit 130, a communication unit 140, a positioning unit 150, and a storage unit 160. The processing unit 130, the communication unit 140, the positioning unit 150, and the storage unit 160 are all coupled to the processing unit 130. The processing unit 130 can be a central processing unit in the smart phone, the communication unit 140 can be a communication interface card, the storage unit 160 can be a micro memory card, and the positioning unit 150 can be a global positioning system (GPS) module. .

FIG. 2 is a flow chart showing an accident warning method according to the first embodiment of the present invention. First, the gravity sensor 115 detects the degree of tilting of the locomotive and the degree of collision (step S210). Then, the processing unit 130 determines whether the degree of tilt and the degree of collision of the locomotive detected by the gravity sensor 115 are greater than a preset value. (Step S220), the preset value depends on the sharpness of the gravity sensor 115. In general, the gravity sensor can include an accelerometer that detects information such as acceleration, velocity, and displacement of the object, thereby knowing the degree of collision of the locomotive. Part of the gravity sensor also adds a gyroscope component to detect the azimuth, so the degree of dumping of the locomotive can be measured. If the answer of the step S220 is NO, the process returns to the step S210. If the determination in step S220 is YES, then the processing unit 130 passes through the gravity sensor 115 to determine whether the vehicle speed of the locomotive is zeroed after a preset time (step S230). If the determination in step S230 is no, the process returns to the step. S210. If the determination in step S230 is also YES, the processing unit 130 determines that the locomotive knight has indeed had an accident. The main purpose of performing step S230 is to prevent erroneous determination. If only the degree of dumping of the locomotive and the degree of collision in S220 are used, there may be a situation of misjudgment, for example, it may be simply a locomotive dumping or a slight collision. After a predetermined period of time, coupled with the judgment of S230, the speed of the locomotive has been zeroed, indicating that the locomotive knight can no longer ride the bicycle, the probability of injury is extremely high, according to which, it is judged that the locomotive knight has indeed had an accident.

If the determination in step S220 and step S230 is YES, the processing unit 130 locates the current position of the locomotive through the positioning unit 150 (step 240). Then, the processing unit 130 sends a warning message including the current location to the emergency ambulance unit 170 via the communication unit 140 (step S250). The warning message may be a text message or a voice message, thereby requesting the ambulance assistance of the emergency ambulance unit 170. Among them, the emergency ambulance unit 170 may be a 119 emergency ambulance line unit, a medical center or a regional hospital of a community medical network.

In other embodiments of the present invention, the storage unit 160 of the mobile device 110 stores an insurance unit preset by the locomotive knight. When the processing unit 130 determines that the locomotive rider has an accident, the processing unit 130 controls the communication unit 140 to send the alert message including the current location to the insurance unit. For example, the insurance unit can be an insurance company insured by a locomotive knight.

In other embodiments of the invention, a mechanism for avoiding traffic jams after a traffic accident is included. The invention utilizes a plurality of speed cameras mounted beside the red street light devices at the intersections to perform speed measurement on the vehicles coming and going near the traffic lights, wherein each traffic light device is equipped with at least one speed camera. The traffic management server 180 of the accident warning system 100 is connected to the mobile device 120, the plurality of speed cameras 181 to 200, and the traffic management server 180 stores the location information of the traffic lights. When the processing unit 130 of the mobile device 120 determines that the locomotive rider has an accident, the processing unit 130 sends a warning message including the current location to the traffic management server 180 via the communication unit 140, and the traffic management server 180 includes the warning message. The current location and the location information of the traffic light devices, wherein at least one specific traffic light device within a radius of two kilometers centered on the current position of the locomotive is selected among the plurality of traffic light devices, and the traffic management server 180 controls the specifics. The speed camera matched with the traffic light device captures the speed measurement photos of at least one specific vehicle under the specific traffic light devices, and analyzes the speeds of the specific vehicles according to the captured speed measurement photos.

As described above, when the traffic management server 180 analyzes that the speed of the specific vehicles is less than 10 kilometers per hour, it is determined that the accident occurred by the locomotive rider has caused traffic jam, and the traffic management server 180 transmits a global positioning system signal. , the warning message is transferred to each vehicle equipped with a row of car navigators. According to this, it is reported that there is an accident in the road section of the majority of passers-by, reminding passers-by not to enter the accident site or to divert traffic early to avoid traffic congestion.

The invention provides an accident warning system and method. In the accident warning system, according to the degree of dumping of the locomotive, the degree of collision and the subsequent speed, it is determined whether the locomotive knight has an accident, and automatically sends a warning message to the emergency ambulance unit to let the injured knight Get early treatment. In addition, the warning message is also sent to the traffic management server. The traffic management server is based on the speed of the traffic around the accident site. If it is determined that the traffic has been jammed, the warning message is transmitted to other vehicles, so that nearby vehicles can be diverted early to avoid causing greater damage. Traffic jam.

While the invention has been described above in terms of various embodiments, it is not intended to limit the invention, and the invention may be modified and modified without departing from the spirit and scope of the invention.
