Shielded laminated variable frequency controller of lift door

Abstract

The invention relates to a shielded laminated variable frequency controller of a lift door, solving the problems of no shielded casing, easy damage, inconvenient debugging and maintenance, and the like of the prior lift door controller. The shielded laminated variable frequency controller comprises a casing, a power driving plate, a main control circuit board, a man-machine interactive circuit board and cooling ribs, wherein the casing is provided with an external interface socket, and the power driving plate, the main control circuit board, the man-machine interactive circuit board and the cooling ribs are assembled in the casing. The shielded laminated variable frequency controller is characterized in that the casing is a shielded casing and forms an integral shielded space together withthe cooling ribs arranged on the bottom of the casing; the power driving plate is fixed on the upper surfaces of the cooling ribs by insulating struts; the cooling ribs are in direct contact with high-power heating elements on the power driving plate; the main control circuit board is connected with the power driving plate by the insulating struts and connecting wires; the man-machine interactivecircuit board is fixedly assembled on the upper surface of the main control circuit board; and the external interface socket arranged on the shielded casing is respectively connected with the main control circuit board and the power driving plate by the connecting wires. The invention has the advantages of reasonable integral structure, shielded function of the casing, obviously improved protection grade and convenient installation and maintenance.

Description

technical field [0001] The invention relates to an elevator door frequency conversion controller, in particular to an elevator door shielding laminated frequency conversion controller with logic control function and frequency conversion function installed on the elevator car top. It is mainly suitable for use on the elevator car top. Background technique [0002] The elevator door is one of the important components of the elevator. When passengers take the elevator, they all need to enter and exit the elevator car through the elevator door. During the operation of the elevator, the main controller of the elevator sends a control command, and then the elevator door controller automatically controls the elevator door. With the rapid development of microelectronic technology, the control of the elevator door has developed from the traditional simple DC control and AC control to the current frequency conversion control. Existing frequency conversion controllers for elevators i...

Problems solved by technology

[0004] The purpose of the present invention is to provide a shielded laminated frequency conversion controller for an elevator door with a reasonable structural design, which fundamentally solves the problems of the existing elevator door controller without a shielded shell, easy damage, and inconvenient debugging and maintenance. The design layout is reasonable, compared with the traditional design, it improves the performance, reduces the cost, improves the work efficiency, and is convenient for installation and maintenance. On the basis of meeting the frequency conversion control function of the elevator door, the shell has a shielding function, which significantly improves the protection level.
