Description of the invention: [Technical field to which the invention pertains] The field of the invention relates to an emergency zone definition and safety system for isolating safe and unsafe areas and guiding people to flee when an accident occurs Unsafe area. The invention also encompasses a method associated with the system. [Prior Art] An emergency alert system has been widely used in the prior art to inform a person to escape from the scene where the accident occurred. An example of this is the US patent 4' 3 4 7 ' 4 9 9 . An emergency evacuation guidance system is proposed which includes an identification mechanism for a plurality of electronic interconnections to provide a series of pulse wave systems that can respond to signals from the switching mechanism to determine the availability of an escape path in the event of an accident. And including a control mechanism to evaluate the input signal of the switching mechanism, and based on the availability of the escape path, the identification mechanism indicates the availability of the escape path in a cyclical manner and in a predetermined pattern. An electronic outlet indicator is provided in another U.S. Patent No. 6,472,994, each of which has a backup power that is mounted on the surface of the non-conductive support mechanism to support the mechanism with considerable toughness and thus can crimp one bit. At the corner. The back of the support mechanism is relatively viscous so that the indicator can adhere to the channel. Moreover, the tape-like support mechanism can be easily disassembled to adjust the electronic components pressed against the surface. In another U.S. Patent No. 5,140,301, an emergency evacuation guidance system is proposed in which laser light is disposed in the structure, the laser light is directed to the escape path, and an accident occurrence indicating mechanism can indicate whether there is an accident in the construction.

When an accident such as a fire occurs in the building, the detecting mechanism detects the occurrence of the accident and generates a detecting signal to generate laser light, which is directed to an escape path. • However, the guidance mechanism described above allows the sound or light to guide the person to escape the accident area. These methods are quite inefficient and cannot meet the actual needs. Moreover, it is also impossible to effectively evacuate the crowd to help solve the problems that occur. Therefore, it is also necessary to propose a new method to solve the problems in the prior art. SUMMARY OF THE INVENTION Accordingly, it is an object of the present invention to provide an emergency zone definition and security system for isolating safe and unsafe areas and directing people to escape unsafe areas when an accident occurs. The invention also encompasses a method associated with the system. In order to achieve the above object, an emergency area defining system is provided in the present invention.

The present invention will be further understood by those skilled in the art, and the description and drawings are made to enable those skilled in the art to understand the objects, features and characteristics of the present invention. Rather than limiting the spirit and spirit of the invention. Referring now to Figures 1 through 5, there is shown an emergency area boundary and a female full system of the present invention. In this embodiment, the emergency area defining and security system of the present invention will be explained. A central control unit 9 is used to integrate other units in the system. A detecting unit 1 is used for detecting an accident that may occur in a building unit 2. A detection unit includes a plurality of detectors, such as detector 11 ' 12 ' 13 ' 14 in FIG. These detectors are installed in different areas to detect the condition of the corresponding area. Each detector is used to detect a corresponding detection zone 111, 112, 113, 114. In the present invention, the number of detectors and detection areas is not limited to four. Other areas are still within the scope of the invention. In the present invention, the building unit 2 is generally a hotel, a hospital, a factory (e.g., a power plant), a station, a railway station, a school, a theater, a ship, a ship, and the like. In the present invention, the hotel is provided with the original alarms 21, 22. An accident or a fire, an earthquake, etc. In the present invention, a fire is taken as an example. Therefore, the H is a fire sensor. An accident determining unit 91 is installed in the central control unit. The accident decision unit 91 receives the signal from the detector and determines that an accident has occurred in the process. The accident decision unit 91 has an accident decision logic unit 910 (please refer to Fig. 3) to determine the accident to occur. The incident decision logic unit 910 stores certain logic to determine an accident that may occur. An area setting unit 92 (please refer to Fig. 3) is used to determine an area 129 which is an unsafe area. For example, in the event of a fire, when three detectors detect a condition, the unsafe area is a combination of detection areas containing multiple detectors. The area setting unit 92 receives signals from the accident decision unit 91 to know that an accident has occurred in those areas, and determines an unsafe area 920 based on the detection area. An isolation unit 6 (refer to Figure 1 now) is used to isolate the unsafe areas 920 and 82. For example, the doors and paths that are isolated to the unsafe area 920. An accident elimination unit 7 (refer to Figure 1 now) is used to eliminate accidents such as sprinkling water in unsafe areas when a fire occurs. A notification unit 3 (please refer to Figs. 1 and 4) for notifying the people in the building unit 2 of the accident. In the present invention, the notification unit 3 includes a wireless transmission unit 3A, and the wireless transmission unit also includes a remote transmission, and when the detector 11 detects an accident, the notification unit 11 detects that an accident has occurred. , j will shoot the aircraft; 31 will send a signal to inform the stems to install at the near door, so people can run to the safe area. However, this is only one aspect of the invention and is not intended to limit the invention. For example, in the factory, the transmitter 31 area is disposed at an escape path. A receiving unit 4 is configured to receive the wireless signal (at least one transmitter 31) from the notification unit 3, so that the information of the occurrence of the accident can be obtained. The receiving unit 4 comprises at least one wireless receiver 41. A guiding unit 5 (Figs. 1 and 5) is used to guide people from an accident area to a safe area. The guiding unit 5 comprises at least one sounding unit 5A. The sounding unit 5A is a wireless transmitter receiver unit 5A comprising at least one transmitter 31 and at least one receiver 41. In the present invention, the transmitter 31 is associated with a corresponding detector, such as the detector 11. If the detector 11 acts to correspond and an accident is detected, 1293744 the associated transmitter 31 will act to transmit a signal. It is necessary to know that the transmitter 31 is outside the area covered by a related detector 11, and that the associated transmitter 31 that is not in the insecure area will transmit a signal to inform people of the escape. The detector 11 is connected to the transmitter 31 in a wired or wireless manner. It is best to use a wireless link because it prevents the cable connection from being destroyed when an accident occurs. / / In the present invention, the f receiver 41/ is mounted on a lock, a flash, an oxygen hood, a remote control, a mobile phone, or an escape suit. • Also in the present invention, the central control unit 9 further includes a display unit 93 (please refer to Fig. 1) to display the status, such as the detection status of the detection unit 1, the unsafe area, and the like. Some subunits are shared with the radio transmitter receiver unit -5 in the present invention. Referring now to Figure 5, one of the units is a sounding unit of 5 Β. The pronunciation unit is used to guide people to escape to a safe area. The pronunciation unit 5A operates in conjunction with the wireless transmitter receiver unit 5A. When the transmitter 31 transmits a notification receiver, the pronunciation unit 5 will act, thus making a sound to cause the person to escape to the safe area. ® The other unit is the lighting unit 5C to emit light to guide people away from the accident area. The lighting unit alerts people to a safe path. Multiple lighting units can be installed on the path to the security or emergency door. Make a strong light to indicate the correct path. Referring now to Figure 5, in the present invention, all of the sub-units 5, 5 and 5C can be integrated in the present invention. That is, the transmitter 31 in unit 5 has associated components. If the transmitter 31 is active, only the associated device connected to the transmitter 31 is activated. Therefore, if a transmitter 31 is close to the accident area, the associated device will not operate, and thus 1293744 people will not go to the path guided by these devices. The circuit structure associated with the transmitter of the present invention is shown in FIG. The projector 31 includes a signal generator 101, an antenna 102, a multiplexer 104 and an encoder 105. Referring now to Figure 7, the receiver 41 includes a detector 521 for detecting the strength of the signal transmitted by the transmitter 31 to the receiver 41. A display is used to display the strength of the signal, a speaker 523. Sound is emitted according to the intensity of the signal, such as a large sound, a strong motion signal, and a lighting unit 524 that emits light to alert people to escape along a predetermined path. Therefore, people in the emergency area can escape the unsafe area based on the volume from the speaker 523. In the present invention, the transmitter 31 is generally mounted at the near emergency door, and the stronger the signal, the louder the sound. The receiver 41 shown in Fig. 7 further includes an antenna 2〇1, a signal processor 2〇2, a demodulator 203, a demultiplexer 204, and a decoder 205. In the present invention, a method of guiding the escape velocity of the antenna wave velocity can also be applied, and the directivity of the antenna beam can be used to design an escape path. Referring now to Figure 8, there is shown a method of defining an emergency zone for disarming an accident in the present invention. The method comprises the following steps: a starting step (801); preparing for the occurrence of an accident in a building unit by using a picker unit, wherein the detector unit comprises a plurality of detectors (step 2) The device is installed at different positions to measure the condition of the corresponding area, and each detector is set to detect the area; receive the signal from the detector, and use _w to determine that an accident has occurred (step 8〇3); an accident decision unit package. 1293744 • Contains an accident decision logic unit to determine whether an accident will occur; the accident decision logic unit stores certain logic to determine a possible accident; using a regional setting The unit defines an unsafe area (step 804), wherein the area setting unit receives the ## from the accident determining unit to determine which area has an accident; for example, determining a safe area according to the detection area; using an isolation unit to The unsafe area is isolated from the secure area (step 805); • an accident elimination unit is used to eliminate the incident in an unsafe area (step 806); Informing the relevant person of the accident (step 807) 'Receive a wireless number from the notification unit using a receiving unit' to learn the information related to the accident (step 8〇8); to guide people from the accident area to safety The area flees (step 8〇9); the status is displayed (step 810). The program ends (step 811). Although the present invention has been described in detail, it is to be understood by those skilled in the art that the invention may be modified and changed without departing from the spirit and scope of the invention. 12 1293744 BRIEF DESCRIPTION OF THE DRAWINGS / Figure 1 is a block diagram of the system of the present invention. 2 shows an example of the configuration of the present invention.
