Specifically, the self-rescue triggering module 300 can be arranged in the elevator car and is in communication connection with the elevator car top plate 200; the self-rescue triggering module 300 sends a self-rescue signal to the elevator control panel 100 through the elevator car top plate 200. The self-rescue triggering module 300 can be a switching device disposed in the elevator car.
When the elevator breaks down and stops running, self-rescue is initiated by trapped people in the elevator car through the self-rescue triggering module 300. In order to prevent false triggering, permission can be set for sending of the self-rescue signal. In addition, in other embodiments, the self-rescue triggering module 300 can also be disposed outside the elevator car, such as in an elevator hall, the machine room 10, and the like, and an external rescuer wirelessly transmits a self-rescue signal to the elevator control panel 100.
Generally, a voice module 500 is provided in the elevator car for outputting voice signals, such as voice prompts for reporting the elevator to reach a floor, open a door, close a door, and the like. The elevator control panel 100 can also output corresponding prompt voice in the self-rescue processing process, and the prompt voice is output through the voice module 500. For example, when the elevator control panel 100 starts the self-rescue module 400, a first prompt voice about starting the self-rescue module 400 is played; after the self-rescue preparation process is completed, playing a second prompt voice about the completion of the preparation; and when the self-rescue treatment is completed, playing a third prompt voice for prompting the user to leave about the completion of the self-rescue treatment.
As shown in fig. 3, in one embodiment, the self-rescue module 400 may include a first main control board 410, a collection unit 420, and a cancellation unit 430. The acquisition unit 420 is connected to the first main control board 410, and is configured to acquire an elevator status signal and a safety switch signal and send the elevator status signal and the safety switch signal to the first main control board 410. Elevator status signals such as whether the elevator is running, locked, floor position at which it is located, etc., safety switch signals such as door lock signals, etc. The first main control board 410 transmits an elevator status signal and a safety switch signal to the elevator control board 100. Whether the self-rescue operation can be started or not is determined by the elevator control panel 100.
The eliminating unit 430 is connected to the first main control board 410, and is used for eliminating an elevator fault signal under the control of the first main control board 410. In an elevator control system, an elevator fault signal is generated when a fault occurs. After the elevator fault signal is received by the elevator control panel 100, the elevator control panel 100 stops the operation of the elevator according to the elevator fault signal, i.e., the operation is locked.

The short-circuit relay can be connected in the safety circuit, the door lock circuit and the car door lock circuit, and carries out short circuit on fault signals generated when the safety circuit, the door lock circuit and the car door lock circuit are in fault, so that the fault signals are invalid.
In one embodiment, the self-rescue module 400 is communicatively connected to the elevator control board 100 via a Modbus.
The elevator control method of an embodiment is also provided below. The method is based on the above-mentioned elevator control system. The method can be started when the elevator is out of order and operates locked.
As shown in fig. 4, in conjunction with fig. 3, the method includes the following steps S110 to S160.
Step S110: the self-rescue triggering module 300 triggers a self-rescue signal and sends the self-rescue signal to the elevator control panel 100. In one embodiment, the self-rescue triggering module 300 can be disposed in the elevator car and communicatively connected to the elevator car roof 200; the self-rescue triggering module 300 sends a self-rescue signal to the elevator control panel 100 through the elevator car top plate 200. The self-rescue trigger module 300 may be a switching device. When the elevator is out of order and stops running, the trapped person can operate the switch device from the elevator, so that the switch device generates a self-rescue signal and sends the signal to the elevator control panel 100 through the elevator car top plate 200.
Step S120: the elevator control panel 100 activates the self-rescue module 400. After the elevator control panel 100 receives the self-rescue signal, the self-rescue module 400 can be started to start the self-rescue process.
The elevator control panel 100 is to start the self-rescue module 400 when the safe operation condition is satisfied. The safe operation condition may be that the following conditions are met simultaneously: the current elevator is not in a maintenance state; the current elevator is not in a shaft self-learning state; the current fault is a safety circuit fault or a door lock circuit fault; the elevator is not in a flat zone. The safe operating conditions may vary from elevator system to elevator system.
Elevator sedan-chair roof 200 can also send voice data for voice module 500 through the MODBUS bus, makes its broadcast voice prompt, for example: "the elevator is preparing to run for self-rescue, do not frighten".
Step S130: the self-rescue module 400 detects the elevator state signal and the safety switch signal and transmits them to the elevator control panel 100. The method of the embodiment mainly aims at self-rescue treatment of safety loop faults and door lock faults, so that elevator state signals and safety switch signals need to be detected.
Step S140: the elevator control panel 100 determines a fault type according to the elevator state signal and the safety switch signal, and performs a self-rescue preparation process according to the fault type.
When the elevator control panel detects that the elevator breaks down, the following two conditions are adopted for judgment:
1) if the current trouble is non-safety circuit and door lock return circuit trouble, then the elevator control panel can handle according to the fault classification level that elevator control system made, if satisfy low-speed operating condition, then the elevator control panel can automatic re-setting this trouble, when not having the trouble and satisfy elevator operating condition, if at non-flat bed, then the elevator control panel can return nearest floor according to the principle of being nearby, behind the elevator flat bed, open the door and put people's back, the elevator deposits the trouble of original newspaper in inside storage space to follow-up elevator dimension personnel discover this trouble when looking over the trouble.
2) If the current fault is a safety circuit fault or a door lock circuit fault, and when the two faults exist in a general elevator control system, the elevator cannot run on an external hardware circuit, so that the method capable of ensuring the running of the elevator is provided in the embodiment when the faults occur.
The types of faults that can be handled for self-rescue mainly include safety circuit faults, door lock faults, and car door lock faults. Whether the fault types belong to can be determined according to the elevator state signals and the safety switch signals acquired by the self-rescue module 400. After the fault type is determined, a self-rescue preparation process is executed. The self-rescue preparation process is mainly used for preparing for the operation of the elevator, and comprises the steps of controlling the self-rescue module 400 to eliminate an elevator fault signal so as to remove the operation locking of the elevator, and determining the operation direction of the elevator and the floor of a flat floor.
Step S150: after the preparation process is finished, the elevator is operated to execute a self-rescue process. After the elevator eliminates the fault signal, the elevator can be operated in a short time under the condition of ensuring safety, and after the elevator reaches a floor where people can get rid of difficulties, people who are trapped can get rid of difficulties.
Elevator sedan-chair roof 200 can also send voice data for voice module 500 through the MODBUS bus, makes its broadcast voice prompt, for example: ' when the elevator self-rescue preparation is finished, the user should press the door opening and closing button to perform self-rescue. Please release the door opening button and the door closing button when the abnormality is found ".
In one embodiment, the elevator control panel 100 can operate the elevator to perform the self-rescue process according to the self-rescue execution command. For example, the execution command is generated by continuously pressing a door open button or a door close button in the elevator car, and disappears after the continuous pressing is cancelled.
Further, after the elevator is operated to perform the self-rescue process in step S150, step S160 may be further performed: the self-rescue is completed. After the trapped person gets out of the way, the fault of the elevator still exists and needs to be done to finish the processing action. Step S160 may include canceling the elevator trouble signal and causing the elevator to re-enter the operation-locked state. A malfunctioning elevator cannot continue to operate after the trapped person has got rid of the trouble, keeping it locked.
Or further, step S160 further includes the step of recording failure information. The recorded fault information can be used for later-stage elevator management personnel and maintenance personnel to carry out troubleshooting and maintenance.
For step S140, different self-rescue preparation processes are performed for different fault types. The following are distinguished:
(1) when the elevator fault is a safety loop fault, the step of executing the self-rescue preparation process according to the fault type comprises the following steps:
step S141: if the short-time operation of the elevator is not affected by the safety loop fault, the elevator control board 100 controls the self-rescue module 400 to carry out short circuit on the corresponding safety loop signal so as to eliminate the locking of the safety loop signal on the elevator.
Step S142: if the safety loop signal is a speed limiter disconnection or tension pulley safety fault signal, the elevator control panel 100 gives an upward running command, otherwise, a direction command is given according to the floor proximity principle. The speed limiter is disconnected or the tension pulley fails, danger can be generated in the descending process, and therefore only an ascending command is given.
(2) When the elevator fault is a door lock loop fault, the step of executing the self-rescue preparation process according to the fault type comprises the following steps:
step S241: the elevator control panel compares the current floor with the door lock failure. The door lock failure refers to a hall door lock failure, and when the hall door lock on a certain floor has a failure, the elevator runs to the floor, and the door lock cannot be opened or closed.
Step S242: and if the current floor is not the adjacent floor of the fault door lock, giving a direction command according to the nearby principle. The running distance of the elevator is minimized nearby, and the safety is ensured.
Step S243: if the current floor is adjacent to the floor of the fault door lock and the current floor is below the floor of the fault door lock, the elevator control board gives a downlink command; otherwise, giving an uplink command. The minimum running distance is ensured, and the elevator cannot run to a floor with a fault, so that the elevator can be taken out of service.
Step S244: after the operation direction is judged, the elevator control panel 100 controls the self-rescue module 400 to carry out short circuit on the corresponding door lock disconnection signal so as to eliminate the locking of the door lock disconnection signal on the elevator. Step S244 may also be performed before step S241, or both may be performed simultaneously. I.e. any order of giving the direction of travel and removing the elevator lock is possible.
(3) When the elevator fault is a car door lock loop fault, the step of executing the self-rescue preparation process according to the fault type comprises the following steps:
step S341: if the door closing in-place signal of the door machine is detected to be effective or the door machine position output signal can reflect that the elevator door is closed, the running direction of the elevator is a direction command given according to the principle of proximity.
Step S342: after the operation direction is judged, the elevator control panel 100 controls the self-rescue module 400 to perform short circuit on the corresponding car door lock disconnection signal so as to eliminate the locking of the car door lock disconnection signal on the elevator.
For the two failure types (1) and (2), as shown in fig. 6a, the step S150 may specifically include:
step S151: starting the elevator to run at a first speed according to the determined running direction; the first speed is less than 0.5 m/s. A typical speed is 0.2 m/s.
Step S152: and when the leveling signal is detected, the vehicle is decelerated and stopped and the door is opened.
For the last type (3) of fault, the step of operating the elevator to perform a self-rescue process comprises:
step S251: the elevator control panel 100 continuously sends a door closing command to the door operator controller. This step ensures that the car door lock is closed and just can make the elevator move, otherwise is difficult to guarantee personnel's in the elevator safety.
Step S252: after confirming that the elevator door is closed, starting the elevator to run at a second speed according to the determined running direction; the second speed is less than 0.2 m/s. A typical speed is 0.1 m/s. The second speed is less than the first speed, i.e., runs at a slower speed, to ensure safety.
Step S253: and when the leveling signal is detected, the vehicle is decelerated and stopped and the door is opened.
After the processing in step S150 is completed, the elevator car top plate 200 may also send voice data to the voice module 500 through the MODBUS bus, so that the voice module plays a voice prompt, for example: 'the elevator finishes self-rescue and please leave the interior of the elevator as soon as possible'.
