Such as an escalator, by implanting electrical control devices such as additional brakes. Because the elevator assembly as a whole has safety gear braking at overspeed, an additional brake is used to stop the elevator when one element in the main machine or the safety gear and its trigger system fails.

Example 2:
as an embodiment of the present invention: as shown in fig. 2, the elevator includes an elevator assembly;
the elevator assembly is provided with a network connection safe operation controller, a main encoder, an auxiliary encoder, a two-way speed limiter, an upper rope clamping device, a lower rope clamping device, an intelligent door lock and a virtual host;

The controller mainly comprises an intelligent sensor, a circuit board (including a chip operating system), software and the like. The auxiliary encoder is arranged on the main shaft of the speed limiter. The intelligent door lock is arranged on the landing door; . The upper and lower rope clamps are arranged on the bearing beam of the main machine; and is used in conjunction with a bi-directional governor (which may be referred to as a trigger device), all known as an elevator additional brake. In addition, a standby power supply (UPS) is configured in the electric control cabinet, and the structure is also an application scene of the invention for real-time implementation
Example 3:
as an embodiment of the invention: the triggering and braking subsystem is also used for judging whether an elevator abnormity exists according to the elevator active detection state and the elevator automatic detection state, and triggering a braking mode of the elevator when the elevator abnormity exists; wherein the content of the first and second substances,
the elevator anomaly comprises: elevator overspeed, elevator accidental movement, and elevator parking anomalies; wherein the content of the first and second substances,
the parking abnormality includes: the contracting brake fails, the traction steel wire rope and the rope groove slip seriously, and the safety tongs and the trigger device thereof fail;
the brake-off mode includes: an overspeed brake mode, an accidental movement brake mode and a parking abnormal brake mode.
The actual operation at the time of acceleration detection is as follows: for example, when the elevator is protected from an overspeed by a factor of 1.15: the braking distance and approximate uniform deceleration of the main brake, the safety gear and the trigger device enter the virtual host for storage and comparison through the main encoder 2, the auxiliary encoder 2 and the controller 7 operating system. In the braking process of the action of the main brake and the safety gear, when the action is compared with a digital model stored by the virtual host, and when the identification system shows that the action is abnormal, the operating system sends an elevator stopping base station instruction; and sends maintenance instructions and information to the elevator. Or displaying that the elevator stops running and is to be repaired.
The braking distance of the main brake is determined according to the standard by the leveling accuracy or the maintenance accuracy value in the technical condition of the elevator, and the braking distance and the deceleration value of the safety tongs are determined by the type test. When the function of the whole machine is checked, a corresponding digital model (data) is established and stored in the virtual host. The value of the uniform deceleration in the full-load braking process is determined to be not more than 1.0 gn; and establishing a digital model of the virtual machine and storing the digital model into the virtual machine. Meanwhile, under the state, a no-load downlink automatic simulation test method is performed; and establishing a digital model of the data, and storing the digital model and the digital model into the virtual host machine as a later action comparison standard value.
After a digital model of the automatic simulation test of the main brake and the safety tongs is established according to the braking distance and the deceleration value of the main brake and the safety tongs, the date of the automatic test of the regular whole machine function is written in and is stored in the virtual host. The time of the regular automatic simulation test is determined according to the use condition of the elevator. Generally, the maintenance time is half a month or year. When the automatic simulation test is carried out each time, the identification system displays that the automatic simulation test is abnormal, and the operating system issues a ladder stopping base station instruction; and sends maintenance instructions and information to the elevator. Or displaying that the elevator stops running and is to be repaired. In addition, each time the elevator automatically simulates the test, the maintenance personnel is advised to arrange the self test and the daily maintenance in the field.
If the service brake and the safety gear act automatically in the simulation test, when the deceleration is less than 1.2 times of the specified minimum value (0.2gn), the vehicle should be stopped immediately, and the vehicle should be restarted after the fault locking is reset. The maintainer should check and maintain its brake system before the failure resets, and take corrective action.
Example 4:
as an embodiment of the invention: during the overspeed braking mode, the method comprises the following emergency braking steps:
step 1: obtaining the braking distance and the braking deceleration of the action of a main brake, a safety gear and a trigger device thereof in the elevator assembly;
step 2: the braking distance and the braking deceleration speed are transmitted to the virtual host through the auxiliary encoder, and are compared with a first standard data model existing in the virtual host to judge whether the elevator is overspeed or not; wherein the content of the first and second substances,
the first standard data model is subjected to automatic simulation test under no load by preset parameters of a main brake and safety tongs, a comparison standard value is set based on a test result, and the standard data model is determined by the comparison standard value;
and step 3: when the elevator is overspeed, emergency braking is carried out.
For an unexpected car movement state at the time of detection: the invention enters the virtual host computer for storage and comparison through the operating systems of the auxiliary encoder 2, the bidirectional speed limiter 3, the upper and lower rope clamps 6, the intelligent door lock 13 and the controller 7 through the braking distance of the additional brake and the approximate uniform deceleration and other numerical values. In the braking process of the additional brake, when the digital model stored in the virtual host is compared with the digital model stored in the virtual host, and when the identification system shows that the digital model is abnormal, the operating system issues an instruction for stopping the elevator base station; and sends maintenance instructions and information to the elevator. Or displaying that the elevator stops running and is to be repaired.
The braking distance of the additional brake is in accordance with the standard, i.e. meets the prescribed value of the term 9.11.5 in the aforementioned standard for elevators GB 7588. When the elevator function is checked, a digital model (data) of the elevator function is established and stored in the virtual host.
