Abstract
The utility model discloses an electric anti-sticking safety system of a lift, comprising a main control chip (MCU1 (Micro-programmed Control Unit 1)) and a cooperative control chip (MCU2), wherein the main control chip (MCU1) is connected with a brake coil (BZ) through a brake contactor (SB); the cooperative control chip (MCU2) is connected with the brake coil (BZ) through a driving relay (YX) and an operation contactor (YXJ); and the operation contactor (YXJ) is connected with the cooperative control chip (MCU2). According to the electric anti-sticking safety system of the lift, one direct-current contactor and one alternating-current contactor are used as two independent electric devices for controlling a lift brake, so as to prevent a fault caused by sticking a contactor contact from occuring when the lift brakes.
Description
Technical field
The utility model relates to the electric antiseized safety system on a kind of elevator.
Background technology
Elevator is the vehicle of a vertical operation in the hoistway of relative closure.Along with the development of national economy, elevator is widely used in various buildings.But elevator faults happens occasionally, and makes troubles to people, even causes the life injury.In the elevator brake process, be one of more common elevator faults owing to the sticking connection of certain contacts of contactor in the electric apparatus causes fault.
The utility model content
The purpose of this utility model is, provides a kind of elevator electric antiseized safety system.The utlity model has when elevator brake, prevent the sticking connection of contacts of contactor and et out of order.
The technical solution of the utility model: the electric antiseized safety system of a kind of elevator, comprise main control chip and Collaborative Control chip, main control chip is connected with brake coil through the band-type brake contactless switch, the Collaborative Control chip is connected with brake coil through driving relay, operation contactless switch, and the operation contactless switch is connected with the Collaborative Control chip.
In the electric antiseized safety system of aforesaid elevator, described main control chip and Collaborative Control chip are micro controller system.
Compared with prior art, the utility model adopts a DC contactor and AC contactor as two of control elevator brake electric apparatuss independently, in the time of can preventing elevator brake, and the sticking connection of contacts of contactor and et out of order.
Description of drawings
Fig. 1 is schematic diagram of the present utility model;
Fig. 2 is the brake coil electric control loop;
Fig. 3 is band-type brake contactless switch electric control loop;
Fig. 4 is operation contactless switch electric control loop.
Being labeled as in the accompanying drawing: the MCU1-main control chip, MCU2-Collaborative Control chip, SB-band-type brake contactless switch, the BZ-brake coil, YX-drives relay, and YXJ-moves contactless switch, MSJ-door lock relay, AQU-safety relay.
The specific embodiment
Below in conjunction with drawings and Examples the utility model is further described, but not as the foundation to the utility model restriction.
Embodiment.The electric antiseized safety system of a kind of elevator, consist of as shown in Figure 1, comprise main control chip MCU1 and Collaborative Control chip MCU2, main control chip MCU1 is connected with brake coil BZ through band-type brake contactless switch SB, Collaborative Control chip MCU2 is connected with brake coil BZ through driving relay YX, operation contactless switch YXJ, and operation contactless switch YXJ is connected with Collaborative Control chip MCU2.Described main control chip MCU1 and Collaborative Control chip MCU2 are micro controller system.
Main control chip MCU1 adopts ARM LPC2378 chip, and Collaborative Control chip MCU2 adopts the C8051F020 chip, and two chip blocks are independently controlled the electric apparatus of separately control, by the serial communication collaborative work, realizes effective work of elevator brake coil BZ.
Control principle of the present utility model: the break-make of main control chip MCU1 control band-type brake contactless switch SB gathers the state of monitoring band-type brake contactless switch SB simultaneously; Collaborative Control chip MCU2 control drives the break-make of relay YX, thereby the break-make of controlling run contactless switch YXJ gathers the state that monitoring moves contactless switch YXJ simultaneously.
The brake coil control loop: as shown in Figure 2, brake coil BZ is moved the open contact of contactless switch YXJ and the two secondary open contacts of band-type brake contactless switch SB are controlled.The two secondary open contacts of band-type brake contactless switch SB are connected on brake coil BZ both sides, can effectively prevent because of contact action asynchronously, and the control loop short circuit causes brake coil BZ accident charged, thereby cause the drg accident to open and have an accident.
Band-type brake contactless switch control loop: as shown in Figure 3, band-type brake contactless switch SB coil is subjected to the normally closed contact of door lock of elevator relay MSJ, the normally closed contact of safety relay AQJ and the control of main control chip MCU1.
Operation contactless switch control loop: as shown in Figure 4, the YXJ coil be subjected to safety relay AQJ normally closed contact, door lock relay MSJ normally closed contact and drive the control of the open contact of relay YX, the 220V ac power supply is adopted in this loop.
Collaborative Control chip MCU2 drives the break-make of relay YX wire loop by control.The control loop output 24V of Collaborative Control chip MCU2 association direct current signal for realizing Collaborative Control chip MCU2 to effective control of high-power AC contactor YXJ, has increased driving relay YX and has realized linear quadratic control between AC contactor YXJ and MCU2 association control loop.
