Description
Technical Field
The present invention relates to the field of elevator control, and more particularly, to a system, method, apparatus, and computer-readable storage medium for elevator fast stopping.
Background
The elevator is a device which vertically moves among different floors in a shaft, a car door is arranged on an elevator car, a shaft door is correspondingly arranged on the wall of the shaft and leads to each floor, and passengers can get in and out of the car by opening the car door and the shaft door. In order to ensure that the elevator can run safely, a plurality of electrical safety devices are arranged on the elevator, and the elevator can run only when each electrical safety device is normal. As shown in fig. 1, there is one safety switch 11 corresponding to each electric safety device, and all the safety switches are connected in series to form a safety chain loop, in the safety chain loop, there are also provided an operating contactor coil S1 and a brake contactor coil S2, in combination with switches Y1 and Y2 controlled by an elevator main control board, the safety chain loop can control on and off of an operating contactor switch K1 and a brake contactor switch K2 in the brake loop shown in fig. 2, thereby realizing power supply control of the brake coil 14 in the brake loop.
In the brake loop, the brake power board 12 does not include a controller, and its input terminal is 220V ac and outputs 110V dc to drive the brake coil 14. When the elevator is normally stopped, a control system (an elevator main control board) controls the operation contactor switch K1 and the brake contactor switch K2 to be disconnected through the switches Y1 and Y2 so that a brake loop is disconnected (namely, a brake coil is disconnected); when abnormal shutdown is caused by abnormal safety switch signals, the running contactor coil S1 and the band-type brake contactor coil S2 are powered off by disconnecting the safety chain loop, so that the running contactor switch K1 and the band-type brake contactor switch K2 are disconnected, and the band-type brake loop is disconnected.
Since the band-type brake coil 14 is an inductive load, after the band-type brake is normally opened, a current loop is formed between the band-type brake power supply board 12 and the band-type brake coil 14, as shown in fig. 3. When the operating contactor switch K1 or the brake contactor switch K2 is turned off with electricity, because the current of the inductor does not suddenly change, at the moment when the operating contactor switch K1 or the brake contactor switch K2 is turned off, electromagnetic energy needs to generate self-induction high voltage by a breakpoint to break through air to maintain current, so that an arc is generated (for example, at the operating contactor switch K1 or the brake contactor switch K2), and energy is released by the heat of the arc. To avoid the generation of the arc, an arc extinguishing device 13 may be connected to the band-type brake coil 14, which forms a new loop with the band-type brake coil 14, and consumes energy in the inductive load by means of the new loop, thereby preventing the generation of the arc, as shown in fig. 4.
However, the arc extinguishing device 13 can only generate a new loop to consume inductive load energy when the operating contactor switch K1 or the contracting brake contactor switch K2 is switched off in a live state, so that the problem of arc discharge cannot be fundamentally solved, and the arc discharge prevention effect is not ideal.

Detailed Description
In order to make the objects, technical solutions and advantages of the present invention more apparent, the present invention is described in further detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the invention and are not intended to limit the invention.

The elevator rapid shutdown system of this embodiment includes electron safety plate 31 and band-type brake power strip 32, and band-type brake power strip 32 and electron safety plate 31 signal connection. Specifically, for example, the band-type brake power supply board 32 and the electronic safety board 31 may be connected by a signal line, and the electronic safety board 31 may directly send a high-level signal or a low-level signal to the band-type brake power supply board 32 through the signal line. The band-type brake power supply board 32 and the electronic safety board 31 may be connected by a CAN bus, a differential signal line, or the like. Those skilled in the art will appreciate that other wired or wireless signal connections are possible.
The electronic Safety board 31 is integrated with Programmable electronic devices, that is, the electronic Safety board 31 is based on PESSRAL (Programmable Electric Systems in Safety Related Applications for Lifts). The electronic safety board 31 in this embodiment is connected to at least one safety switch and detects a signal state of the at least one safety switch, and when the signal state of the safety switch is abnormal, the electronic safety board 31 generates a shutdown signal and sends the shutdown signal to the band-type brake power supply board 32.

Fig. 7 is a schematic view of an elevator rapid stopping system according to another embodiment of the present invention. Unlike the embodiment shown in fig. 5, the elevator rapid-stopping system in this embodiment includes a main control board 44 in addition to an electronic safety board 41 and a band-type brake power supply board 42. Specifically, the main control panel 44 may be constituted by a control panel for controlling the operation of the elevator in the elevator control system.
In this embodiment, the electronic safety board 41 may send a status signal including the status of each safety switch to the main control board 44 (e.g., according to a preset cycle), so that the main control board 44 may know the status of the electronic safety board 41 (including the status of each safety switch) in real time. When the state signal from the electronic safety board 41 does not meet the preset condition (for example, the safety switch connected to the electronic safety board 41 is abnormal), the main control board 44 sends a control instruction to the second logic processing unit of the band-type brake power supply board 42, where the control instruction is used for enabling the second logic processing unit to control the rectifying unit to stop supplying power and outputting power. The electronic safety board 41 and the main control board 44, and the main control board 44 and the band-type brake power supply board 42 can respectively adopt serial communication buses for information interaction.
In the present embodiment, the brake power supply board 42 can cut off power supply to the brake circuit of the brake based on either one of the stop signal from the electronic safety board 41 and the control command from the main control board 44 to brake the elevator, thereby improving safety.
The band-type brake braking loop comprises a band-type brake contactor switch K42, an operation contactor switch K41 and a band-type brake coil 43, and the band-type brake coil 43 is connected with the direct current output end of the rectifying unit of the band-type brake power supply board 42 through the operation contactor switch K41 and the band-type brake contactor switch K42. The elevator rapid stopping system also comprises a switch control loop, wherein the switch control loop comprises a first branch, a second branch and a safety relay K43, the first branch and the second branch are connected between the high-voltage sampling point A and a reference ground in parallel, and the safety relay K43 is connected between a power supply and the high-voltage sampling point A; the first branch circuit comprises a first switch Y41 and a band-type brake contactor coil S42 which are connected in series and used for conducting on-off control on a band-type brake contactor switch K42, and the second branch circuit comprises a second switch Y42 and a running contactor coil S41 which is connected in series and used for conducting on-off control on a running contactor switch K41.
The first switch Y41 and the second switch Y42 may specifically adopt a contactor, a thyristor or other semiconductor switching elements, and control ends of the first switch Y41 and the second switch Y42 are connected to the main control board 44, that is, the on/off is controlled by the main control board 44. And the control terminal of the safety relay K43 is connected to the first logic processing unit of the electronic safety board 41, that is, the safety relay K43 is switched on and off by the first logic processing unit. When the state signal from the electronic safety board 41 does not meet the preset condition, the main control board 44 sends a control instruction to the internal contracting brake power panel 42, and controls the first switch Y41 and the second switch Y42 to be switched off; when a signal of any detection terminal is abnormal, the first logic processing unit of the electronic safety board 41 controls the safety relay K43 to be switched off, and the brake contactor coil S42 and the operation contactor coil S41 are powered off, so that the brake contactor switch K42 and the operation contactor switch K41 are switched off, and the brake coil 43 is powered off, so that an elevator brake device brakes.
In addition, the main control board 44 may further include a voltage detection unit, and is connected to the high voltage sampling point a of the switching control loop through the voltage detection unit, so that the main control board 44 may detect the voltage of the high voltage sampling point a. Correspondingly, when the main control board 44 detects that the voltage of the high-voltage sampling point a is lower than the preset voltage, the first switch Y41 and the second switch Y42 are controlled to be turned off, and meanwhile, a control instruction is sent to the second logic processing unit of the band-type brake power panel 42, so that the second logic processing unit controls the rectifying unit to stop power supply output. Because the contracting brake contactor switch K42 and the operating contactor switch K41 are slow in execution time, a control command is firstly given to the contracting brake power panel 42, and the contracting brake power panel stops outputting the direct-current contracting brake power. Therefore, when the machine is abnormally stopped, high-voltage direct current does not exist in a loop of the internal contracting brake before the operation contactor switch K41 and the internal contracting brake contactor switch K42 are disconnected, so that arc discharge cannot be generated, and the problem of arc discharge is solved.
As shown in fig. 8, an embodiment of the present invention further provides a method for quickly stopping an elevator, which is applicable to an elevator system and includes:
step S81: the electronic safety board detects the state of the safety switches, and particularly, the electronic safety board may be connected with a plurality of safety switches (including sensors) through detection terminals. The electronic Safety board is integrated with Programmable electronic equipment, namely the electronic Safety board is based on PESSRAL (Programmable electronic equipment for elevator Safety Related Applications).
Step S82: when the signal of any safety switch is abnormal (namely the signal of any detection terminal is abnormal), the electronic safety board outputs a stop signal to the band-type brake power supply board. The band-type brake power supply board comprises a rectifying unit and supplies power to a band-type brake circuit through a direct current output end of the rectifying unit. In the brake loop of the band-type brake, a coil of the band-type brake is connected to a direct current output end of the rectifying unit through a band-type brake contactor switch and a running contactor switch in sequence.
Step S83: after the band-type brake power panel receives a stop signal from the electronic safety panel, the rectifying unit is controlled to stop power supply output.
According to the elevator quick stop method, the electronic safety board acquires the state of the safety switch, and the power supply of the brake loop of the band-type brake is cut off by the band-type brake power supply board when the state of the safety switch is abnormal, so that the elevator quick stop method can be used for quickly stopping the elevator, and the problem of arc discharge caused by disconnection of the brake loop of the band-type brake when the elevator is abnormally stopped is solved.
As shown in fig. 9, in another embodiment of the present invention, the method for rapidly stopping an elevator further includes, in addition to steps S81-S83:
step S91: the electronic safety board sends a status signal (e.g., according to a preset period) to a main control board for controlling the operation of the elevator, so that the main control board can know the status of the electronic safety board (e.g., the status of each safety device) in real time.
Step S92: when the state signal from the electronic safety board does not accord with the preset condition (for example, the safety switch connected with the electronic safety board is abnormal), the main control board sends a control instruction to the band-type brake power supply board, and the control instruction is used for enabling the band-type brake power supply board to control the rectifying unit to stop supplying power and outputting power.
In this embodiment, the brake power supply board can cut off power supply to the brake circuit of the brake according to any one of the stop signal from the electronic safety board and the control command from the main control board, so as to brake the elevator and improve safety.
As shown in fig. 10, in another embodiment of the present invention, the method for rapidly stopping an elevator further includes steps S81-S83, in addition to the steps:
step S101: when the state signal from the electronic safety board does not meet the preset condition (for example, the safety switch connected with the electronic safety board is abnormal), the main control board controls a first switch in a first branch and a second switch in a second branch of a switch control loop to be switched off, wherein the first branch and the second branch are connected between the high-voltage sampling point and the reference ground in parallel. Specifically, the first branch circuit comprises a first switch connected in series and a band-type brake contactor coil for controlling the on-off of a band-type brake contactor switch in a band-type brake braking loop, and the second branch circuit comprises a second switch connected in series and an operation contactor coil for controlling the on-off of an operation contactor switch in the band-type brake braking loop.
Step S102: when the signal of any detection terminal of the electronic safety board is abnormal, the safety relay in the switch control loop is controlled to be disconnected, and in the switch control loop, the safety relay is connected between the power supply and the high-voltage sampling point, so that the elevator is stopped.
In addition, the elevator rapid stopping method can further comprise the following steps: the main control board obtains the voltage of the high-voltage sampling point of the switch control loop, controls the first switch and the second switch to be disconnected when the voltage of the high-voltage sampling point is lower than a preset voltage, and simultaneously sends a control instruction to the band-type brake power panel to enable the band-type brake power panel to control the rectifying unit to stop power supply output.
