After the power supply is cut off, under the power conversion of the power conversion device 42, the required power is continuously supplied, and the regional control center A0 also transmits the control signal to the elevator system 3, the display device M1, M2, and the illumination. Device L and broadcast P to indicate the person's escape route.

In the state of no fire alarm, mainly maintaining the ambient temperature and air quality of the public space 23 and the machine room 22 of each floor, and the power system 4 supplies all the required power by the public power supply unit 41. In this state, the first sensor S1 The measured first ambient temperature value TA1 and the first smoke detection value CA1 are controlled at a temperature of TA1+X1<T1 (X1 is a first set difference value, T1 is a first set temperature value), and ambient air The quality is maintained at CA1+X2<C1 (X2 is the second set difference, and C1 is the first set smoke detection value). At this time, the first fan 511 of the intake and exhaust device 51 is exhausted. The second fan 512 is used for intake air operation, and the air supply condition is regulated air supply (please refer to the fourth figure); but when CA1+X2≧C1 indicates that the air quality is too poor, the carbon dioxide (CO2) may be too high, or The smog condition has affected the normal air quality. At this time, the regional control center A0 controls the first fan 511 and the second fan 512 of the air intake and exhaust device 51 to be mandatory air supply, and is restored only when CA1+X2<C1. For regulated air supply operation.

When a fire alarm occurs, the public power supply unit 41 is shut off, and the power conversion device 42 immediately switches to the power generation device 43 to continue power supply under the command of the regional control center A0. In this state, the first sensor S1 is The measured first ambient temperature value TA1 or the first smoke detection value CA1 has a condition that conforms to TA1+X1≧T1 or CA1+X2≧C1 (as shown in the fourth figure), indicating that the fire condition has threatened the person to flee The safety of the regional control center A0 will control the exhaust device 51 to be converted into a mandatory air supply by the conditioned air supply, that is, the operation of the first fan 511 and the second fan 512 is the air supply, so that the air inlet is sent through the air supply duct. The damper (or fan) D1 of the air supply port 521 in the ladder of 52 and the damper (or fan) D2 of the air supply port 231 of each floor are sent out at full speed, and a positive pressure safety escape ventilation environment is formed to facilitate the escape of personnel; as for the public space of each floor 23, the detection of the second sensor S2, as a basis for judging whether the area is a safe escape area, or a dangerous area, and providing the basis for the area control center A0 to control whether the elevator 32 can be parked on the floor, when Two sensors S2 The measured second ambient temperature value TA2 and the second smoke detection value CA2 are compared by the regional control center A0. Act according to the following conditions (please refer to the fifth figure):

(1) When TA2+X3≧T2 or CA2+X4≧C2 (T2 is the second set temperature value, C2 is the second set smoke detection value, X3 is the third set difference value, and X4 is the fourth set difference value. ), indicating that the floor is a dangerous area (ie, a disaster area), so the elevator car 32 is forced to stop, and the broadcast on the screens of the display devices M1 and M2 and the broadcast P will reveal the message for reference of the personnel escape route.

(2) When TA2+X3<T2 or CA2+X4<C2, it means that the floor is a safe escape area, the elevator car 32 can be parked and transported, and the synchronization is also displayed on the screen of the display devices M1 and M2 and the broadcast P broadcast. A message to indicate the escape route of the person.

Furthermore, the above-mentioned regional control center A0 of the present invention can directly connect with the main control center A and accept its instructions, and can directly control the systems and devices in the area independently in the case of external connection interruption. Commands to maintain the normal operation of the escape function; in addition, the general control center A can also timely grasp the status of each floor and each area of the building through the connection with the regional control center A0, through the display devices M1, M2 Provide instructions for the person's best escape route to ensure that the casualties of the firefighters are mitigated.
