By connecting the brake module 17 to the backup power module 16, power support can still be provided to the brake module 17 by the backup power module 16 even in the event of a power failure, ensuring the safe braking of the car 103. Such a design improves the safety and reliability of the elevator system and improves the safety performance of the machine roomless elevator.

[0044] In one embodiment, the car 103 further comprises a communication board 18; the first end T1 of the communication board 18 is connected with the position sensor, and the second end T2 of the communication board 18 is connected with the third end W3 of the microcomputer board 11; the communication board 18 is further connected in communication with the cloud system for sharing the car 103 data to the cloud system.

[0047] Specifically, when the car 103 arrives at the rescue floor door area, the digital display board S01 of the elevator hall-out control or the remote device will display the floor where the car 103 stops and the signal that the car 103 has arrived at the door area, which facilitates the rescue personnel to quickly understand the elevator position and carry out quick rescue.

[0048] More, in one embodiment, the elevator emergency rescue system further comprises a first external power supply D1 and a second external power supply D2; the sixth end W6 of the microcomputer board 11 is connected with the first external power supply D1, and the fourth end of the frequency converter 12 is connected with the second external power supply D2.

[0050] In an exemplary embodiment, the microcomputer board 11 is also used to determine the rescue operation direction of the car 103 based on the floor information and location information of the car 103.

[0051] Specifically, after the elevator learns the floor height, the microcomputer board 11 can obtain the distance between adjacent floors. When an emergency rescue is needed, the microcomputer board 11 obtains the distance between the position of the car 103 and the nearest floor above and below, compares them, selects the floor corresponding to the smallest distance, and confirms the direction of the car 103 running towards that floor as the direction of the car 103 during the rescue. Furthermore, the rescue running direction of the car 103 not only depends on the distance between the position of the car 103 and the nearest floor above and below, but also takes into account the time it takes for rescuers to reach the rescue floor, the convenience of deploying rescue equipment on different floors, etc., and determines the rescue running direction of the car 103.
