Detailed ways

Embodiments of the present invention are described in detail below, examples of which are shown in the drawings, wherein the same or similar reference numerals designate the same or similar elements or elements having the same or similar functions throughout. The embodiments described below by referring to the figures are exemplary and are intended to explain the present invention and should not be construed as limiting the present invention.

The detection method, device, elevator, electronic equipment and computer-readable storage medium of the brake equipment in the elevator according to the embodiments of the present invention will be described below in conjunction with the accompanying drawings.

In an embodiment of the present invention, the braking device in the elevator includes a mechanical braking device and an electrical braking device.

It is understandable that there are differences in the braking function of mechanical braking devices and electrical braking devices. A mechanical braking device stops the elevator from moving, an electrical braking device causes the elevator to move at a slower speed, ie the braking function of the mechanical braking device is better. When the elevator needs to brake, the braking function of the mechanical braking device is used first to realize the braking of the elevator. When the braking function of the mechanical braking device fails, the braking function of the electrical braking device is used to realize the braking of the elevator.

It should be noted that the structure and type of the mechanical braking device and the electrical braking device are not limited too much. For example, the moving iron core of the electromagnet in the mechanical braking device can adopt a plunger structure, and the electrical braking device can be a permanent magnet synchronous motor.

Fig. 1 is a flow chart of a detection method for braking equipment in an elevator according to an embodiment of the present invention.

S101. Identify whether the detection condition of the electric braking device is satisfied currently.

In the embodiment of the present invention, it can be identified whether the detection condition of the electric braking device is currently satisfied. It can be understood that the detection condition can be set according to the actual situation, and there is no excessive limitation here.

In one embodiment, the detection conditions include at least one of the following:

Condition 1. The current time reaches the preset target detection time.

In the embodiment of the present invention, the target detection time may be preset according to the actual situation. For example, the target detection time can be set to 24:00 in the morning, 1:00 in the morning, etc. Further, the current time may be acquired, and compared with the target detection time, and if the current time reaches the target detection time, it is recognized that the detection condition of the electric braking device is met.

In one embodiment, the current time can be obtained through a timer in the elevator. For example, a timer can be installed in the electric control unit in the elevator.

Condition 2: The duration for which the elevator has not received a service request is greater than or equal to a third preset threshold.

In an embodiment of the invention, an elevator may receive a service request. Wherein, the service request refers to the user's request to take the elevator. For example, the user can press the elevator buttons such as "Up", "Down", "Open the door", "Close the door" and any floor to send a service request to the elevator. The electric control device of the elevator can detect whether the elevator button is pressed. When any elevator button is pressed, it is determined that a service request is received.

In the embodiment of the present invention, the duration for which the elevator has not received a service request can be obtained. If the above duration is greater than or equal to the third preset threshold, it indicates that the duration for which the elevator has not received a service request is longer, that is, the elevator has no service request at this time. It can be identified that the current detection conditions for electric braking equipment are met.

Wherein, the third preset threshold can be set according to the actual situation, which is not limited here. For example, the third preset threshold may be set to 1 minute.

S102, in response to the current meeting of the detection condition, control the elevator to enter the non-service state.

In the embodiment of the present invention, the elevator can be controlled to enter the non-service state in response to the current meeting of the detection condition. It should be noted that when the elevator enters the non-service state, it will not respond to service requests. For example, when the elevator enters the non-service state, if the user presses the "up" elevator button to send a service request to the elevator to move to the user's floor, the elevator will not respond to the service request, that is, the elevator remains stationary.

It can be understood that in this solution, when the detection conditions of the electric brake equipment are currently satisfied, the elevator can be controlled to enter the non-service state, which can avoid the situation that there are passengers in the elevator when the electric brake equipment is detected, and helps to protect the user personal safety.

S103. Obtain the first detection process of the electric braking device, and control the elevator to start the first detection process.

In the embodiment of the present invention, the first detection process of the electric braking device can be set according to the actual situation, without too much limitation here, and the first detection process is stored in the storage space of the elevator, for example, the first detection process can be Stored in the storage space of the elevator's electric control device.

In one embodiment, the first detection process can be set to:

Step 1, control the elevator to stop at the limit position;

Wherein, the limit position refers to the position where the moment difference between the elevator car and the counterweight is the largest.

It can be understood that when the elevator stops at the limit position, the corresponding electrical braking speed is the largest, and the detection effect of the electrical braking device is the best.

Step 2, releasing the mechanical braking device;

Step 3, controlling the drive equipment (such as traction motor, frequency converter, etc.) to be in a non-output state (no torque output).

Step 4, detecting the electric braking speed of the elevator.

Taking the elevator car with no load as an example, the weight difference between the car and the counterweight will generate a downward moment, and the car will move upward under the action of the downward moment, and the electric braking device (such as a permanent magnet synchronous motor) will Under the action of the downward moment, an upward moment that hinders the upward movement of the car is generated. When the upward moment and the downward moment are balanced, the car will move upward at a slower speed.

For example, as shown in Figure 2, the elevator 100 includes a main power supply 11, a main switch 12, a frequency converter 13, a main contactor 14, a star-off contactor 15, a permanent magnet synchronous motor 16, a brake 17, an encoder 18, and a controller 19 , brake power supply 20, brake contactor 21, sensor group 22, etc. It should be noted that the brake 17 is a mechanical braking device, and the permanent magnet synchronous motor 16 is an electrical braking device.

Wherein, the controller 19 includes a main contactor state monitoring module 191 , a star-off contactor state monitoring module 192 , a brake contactor state monitoring module 193 , and a brake brake state monitoring module 194 . The controller 19 can monitor the main contactor 11 and the star contactor 15 respectively through the main contactor status monitoring module 191, the star-off contactor status monitoring module 192, the brake contactor status monitoring module 193, and the brake brake status monitoring module 194. , brake contactor 21, and the brake of the brake 17 carry out state monitoring.

The first detection process corresponding to Fig. 2 can be set as:

Step 1, control the elevator to stop at the limit position;

Step 2. The control controller 19 sends the brake command to the brake power supply 20, and based on the brake command, the brake contactor 21 is turned on, so that the brake power supply 20 supplies power to the brake 17, and then the brake 17 is released.

Step 3: Control the frequency converter 13 to be in a non-output state (no torque output), and disconnect the main contactor 14 .

Step 4. Detect the electrical braking speed of the elevator.

Optionally, detecting the electrical braking speed during the braking process of the elevator may include the following two possible implementations:

Method 1. The encoder 18 collects the speed signal of the elevator, and feeds the speed signal back to the controller 19, and the controller 19 obtains the electric braking speed based on the speed signal.

Mode 2: The speed sensor in the sensor group 22 collects the speed of the car, and feeds back the speed of the car to the controller 19 .

S104. Acquire first detection data corresponding to the first detection process, where the first detection data includes at least the electric braking speed of the elevator.

In the embodiment of the present invention, the first detection data will be generated in the first detection process, and the first detection data at least includes the electric braking speed of the elevator. It can be understood that the electric braking speed refers to the speed of the car during the electric braking process of the elevator.

In one embodiment, the first detection data may include the running data of the elevator, such as the displacement of the elevator during the electrical braking process, the braking torque, braking force, and torque current generated by the electrical braking equipment.

In an implementation manner, the first detection data may be acquired by a sensor. Wherein, the sensor may include a displacement sensor, a torque sensor, a force sensor, a current sensor, a speed sensor, etc., which are not limited here too much. For example, the speed of the car can be detected by the speed sensor to obtain the electric braking speed.

S105, identifying that the electric braking speed is greater than a first preset threshold, and determining that the braking function of the electric braking device is invalid.

It should be noted that, in the embodiment of the present invention, the first preset threshold is the critical value for judging the failure of the braking function of the electric braking device, which can be set according to the actual situation and is not limited here. For example, it can be set as 0.3 m/s. Identifying that the electrical braking speed is greater than the first preset threshold indicates that the electrical braking speed is faster at this time, and the safety of the elevator electrical braking is lower, and it can be determined that the braking function of the electrical braking device is invalid.

In one embodiment, after it is determined that the braking function of the electric braking device fails, a reminder message for reminding the braking function of the electric braking device to fail can be generated, so as to inform the user of the failure of the braking function of the electric braking device in time , so as to repair and replace the electric braking equipment in time. Wherein, the reminder message may carry the identification information of the elevator and the electric braking equipment. For example, a reminder message can be sent to the server.

To sum up, according to the detection method of the braking equipment in the elevator according to the embodiment of the present invention, it can identify whether the detection condition of the electric braking equipment is currently satisfied, and when the detection condition is currently satisfied, the elevator is controlled to enter the non-service state, and the elevator is controlled to start In the first detection process of the electric braking device, if it is identified that the electric braking speed is greater than the first preset threshold, it can be determined that the braking function of the electric braking device is invalid. Therefore, the method can automatically detect the electric braking equipment during the elevator use, and accurately judge the effectiveness of the electric braking equipment according to the electric braking speed, which can save the detection cost and help to improve the safety of the elevator braking. To ensure the personal safety of users.

On the basis of any of the above-mentioned embodiments, after obtaining the first detection data corresponding to the first detection process in step S104, it may include identifying that the electric braking speed is less than or equal to the first preset threshold, indicating that the electric braking speed is relatively low at this time. Slow, the safety of elevator electrical braking is high, and it can be determined that the braking function of the electrical braking equipment has not failed.

In one embodiment, after it is determined that the braking function of the electric braking device has not failed, the elevator can be controlled to end the detection process and enter the service state. It should be noted that when the elevator enters the service state, it can respond to the service request. Therefore, after determining that the braking function of the electric braking device has not failed, the method can immediately end the detection process, so that the elevator can provide services, ensure the normal use of the elevator, and meet the needs of users.

On the basis of any of the above embodiments, as shown in FIG. 3, after determining that the braking function of the electric braking device fails in step S105, it may include:

S301. Obtain a second detection process of a mechanical braking device, and control the elevator to start the second detection process.

In the embodiment of the present invention, the second detection process of the mechanical braking device can be set according to the actual situation, without too much limitation here, and the second detection process is stored in the storage space of the elevator, for example, the second detection process can be Stored in the storage space of the elevator's electric control device.

In one embodiment, before controlling the elevator to start the second detection process, it may include controlling the elevator to exit the first detection process, so as to stop the detection process of the electric braking device.

For example, continuing to take FIG. 2 as an example, controlling the elevator to exit the first detection process may include controlling the controller 19 to send a brake release command to the brake power supply 20, and disconnect the brake contactor 21 based on the brake release command.

S302. Acquire second detection data corresponding to the second detection process, where the second detection data includes at least the braking force of the mechanical braking device.

In the embodiment of the present invention, the second detection data will be generated in the second detection process, and the second detection data includes at least the braking force of the mechanical braking device.

In one embodiment, the second detection data may include elevator operation data, such as displacement of the elevator during mechanical braking, mechanical braking speed, braking torque generated by mechanical braking equipment, and the like. It can be understood that the mechanical braking speed refers to the speed of the car during the mechanical braking process of the elevator.

In an implementation manner, the second detection data may be acquired by a sensor. Wherein, the sensor may include a displacement sensor, a torque sensor, a force sensor, a speed sensor, etc., which are not limited here too much. For example, the speed of the car can be detected by the speed sensor to obtain the mechanical braking speed, and the braking force can be detected by the force sensor.

S303, identifying that the braking force is less than a second preset threshold, and determining that the braking function of the mechanical braking device is invalid.

It should be noted that, in the embodiment of the present invention, the second preset threshold is a critical value for judging that the braking function of the mechanical braking device fails, which can be set according to actual conditions, and is not limited here. Identifying that the braking force is smaller than the second preset threshold indicates that the braking force is small at this time, and the safety of the elevator mechanical braking is low, and it can be determined that the braking function of the mechanical braking device is invalid.

In one embodiment, after it is determined that the braking function of the mechanical braking device fails, it may include controlling the elevator to enter a stop running state. It should be noted that when the elevator enters the stop running state, it cannot respond to service requests. It is understandable that at this time, the braking functions of both the electrical braking device and the mechanical braking device fail, and the safety of the elevator is low, so the elevator can be controlled to enter the stop running state, so that the elevator cannot provide services, and the user's personal safety is guaranteed. Safety.

Optionally, before controlling the elevator to enter the stop running state, it may include controlling the elevator to exit the second detection procedure, so as to stop the detection process of the mechanical braking device.

In one embodiment, after it is determined that the braking function of the mechanical braking device is invalid, a reminder message for reminding the mechanical braking device that the braking function is invalid can be generated, so as to inform the user that the braking function of the mechanical braking device is invalid , so as to repair and replace the mechanical brake equipment in time. Wherein, the reminder message may carry identification information of elevators and mechanical braking equipment. For example, a reminder message can be sent to the server.

Therefore, the method can control the elevator to start the second detection process of the mechanical braking device after determining that the braking function of the electrical braking device is invalid. If it is identified that the braking force of the mechanical braking device is less than the second preset threshold, it can be determined The braking function of the mechanical braking device fails, that is, the method can automatically detect the mechanical braking device after the braking function of the electrical braking device is determined to be invalid, and accurately judge the effectiveness of the mechanical braking device according to the braking force. It helps to improve the safety of elevator braking and guarantees the personal safety of users.

On the basis of any of the above embodiments, after obtaining the second detection data corresponding to the second detection process in step S302, it may include identifying that the braking force is greater than or equal to the second preset threshold, indicating that the braking force is relatively large at this time, and the elevator machinery The safety of braking is high, and it can be determined that the braking function of the mechanical braking equipment has not failed.

In one embodiment, after it is determined that the braking function of the mechanical braking device has not failed, the elevator can be controlled to end the detection process and enter the service state. It should be noted that when the elevator enters the service state, it can respond to the service request. Therefore, after determining that the braking function of the mechanical braking device has not failed, the method can immediately end the detection process, so that the elevator can provide services, ensure the normal use of the elevator, and meet the needs of users.

On the basis of any of the above-mentioned embodiments, after obtaining the first detection data corresponding to the first detection process in step S104, it may include obtaining the reference speed of the electric braking speed, identifying that the electric braking speed is greater than the reference speed, and less than or equal to If the first preset threshold is used, then it is determined that the electric braking device needs to be maintained.

Wherein, the reference speed refers to the optimal speed of the electric braking speed. For example, during the elevator installation and commissioning stage, the electrical braking speed of the elevator under no-load and/or full-load conditions can be detected and used as a reference speed.

It can be understood that if the electrical braking speed is greater than the reference speed, it indicates that the braking performance of the electrical braking equipment is degraded, and the electrical braking equipment may have problems such as corrosion and aging with use, and it can be determined that the electrical braking equipment needs to be repaired.
