[0051] figure 1 It is a flow chart of an elevator brake control method provided by Embodiment 1 of the present invention. This embodiment is applicable to the situation of powering on, opening and braking a variety of brakes of different specifications. This method can be controlled by the embodiment of the present invention The provided elevator brake control device is implemented. This device can generally be integrated in the main control system and used in conjunction with the brake power supply. The device can be implemented in the form of software and / or hardware. refer to figure 1 , the method may specifically include the following steps:

[0052] S110. Determine the type of the host and the type of the brake matched with the host according to the frequency converter communicating with the host.

[0053]Specifically, a variable-frequency drive (VFD) is a power control device that uses frequency conversion technology and microelectronics technology to control an AC mot...

Embodiment 2

[0060] Figure 2a It is a flow chart of an elevator brake control method provided by Embodiment 2 of the present invention, and this embodiment is implemented on the basis of the foregoing embodiments. refer to Figure 2a , the method may specifically include the following steps:

[0061] S210. Determine that the communication state between the braking power supply and the microcontroller is abnormal.

[0062] Specifically, the abnormal communication state in the embodiment of the present invention may include an abnormality in the communication line, that is, normal data transmission cannot be performed between the brake power supply and the microcontroller; the abnormal communication state may also refer to the elevator braking device The microcontroller is not included, that is, the brake power output mode is controlled by the main control system and not controlled by the microcontroller.

Abstract

The embodiment of the invention discloses a control method and device of an elevator brake, the brake, equipment and a storage medium. The model of a host and the model of the brake matched with the host are determined according to a frequency converter in communication with the host; matched information of an output mode of a brake power source is received, wherein the matched information comprises the correspondence relationship between the model of the brake and the output mode of the brake power source, and the correspondence relationship is determined according to output parameters of thebrake power source; and the brake is instructed to run according to the output mode, corresponding to the brake, of the brake power source. It is achieved that a same elevator brake device is applicable to various brakes, the universality of the elevator brake device is improved, and the configuration difficulty of an electrical system is lowered.

Description

technical field [0001] The embodiments of the present invention relate to electrical control technology, and in particular to a control method, device, brake, equipment and storage medium of an elevator brake. Background technique [0002] Elevator brakes, commonly known as holding brakes, generate two-way electromagnetic thrust when energized to separate the brake mechanism from the rotating part of the motor. When the power is turned off, the electromagnetic force disappears, and a brake is formed under the action of the external brake spring pressure. The brake and the driving motor of the traction machine are matched to form an electromagnetic braking three-phase asynchronous motor, which realizes the occasion of quick start and safe braking of the elevator. The elevator brake plays an important safety role in the elevator control system. Every normal operation and start and stop of the elevator requires the participation of the brake. [0003] At present, there are man...
