Description

Technical Field

[0001] This invention relates to the field of elevator technology, and in particular to an emergency detection method and system for elevators in dangerous conditions. Background Technology

[0002] The elevator's braking system is the most crucial component ensuring safe elevator operation. During operation, it frequently experiences problems such as brake electromagnet failure (demagnetization, jamming, etc.), brake shoe wear, component failure (brake spring failure, brake arm breakage, pin loss, etc.), and brake malfunction (caused by the control system). These issues inevitably lead to accidents such as overshooting, undershooting, and shearing during elevator car operation. Traditional elevator braking systems and control systems cannot solve these problems, relying solely on maintenance inspections at least every 15 days to detect potential hazards. Once a problem occurs, it can lead to injuries or fatalities, along with damage to the elevator equipment and the building, making rescue operations extremely difficult. Therefore, there is an urgent need for a technology that can promptly detect elevator malfunctions and provide timely preventative measures. Summary of the Invention

[0029] Figure 2 This is a signal block diagram of the present invention. Detailed Implementation

[0030] To facilitate understanding by those skilled in the art, the present invention will be further described below with reference to embodiments and accompanying drawings. The content mentioned in the embodiments is not intended to limit the present invention. The present invention will be described in detail below with reference to the accompanying drawings.

[0031] Example 1:

[0032] This embodiment provides an emergency detection method for elevators in hazardous conditions, such as... Figures 1 to 2 A corresponding central controller and data terminal can be set up. The central controller processes and judges the acquired working data to achieve self-monitoring of elevator structures such as brakes. The data terminal can easily receive the relevant elevator operating status so that staff can understand it in a timely manner. Specifically, this includes the following methods:

[0033] S1. Acquire elevator operating data; the elevator operating data includes the operating data of the car doors, the position data of the car, and the operating data of the brakes; the elevator operating data can be collected by setting up relevant sensors.

[0034] S2. Based on the acquired elevator working data, determine the elevator's abnormal malfunctions and control the elevator to run to the top or bottom floor according to the car's load. After the elevator runs to the top or bottom floor, fix the car using the emergency stop device pre-installed in the elevator.

[0035] S3. Determine the effectiveness of the elevator's brake; if the brake is effective, the elevator is in a state where the elevator landing door can be opened and the elevator main power supply can be disconnected; if the brake is ineffective or no determination of brake ineffectiveness is made, the elevator is in a state where the elevator landing door cannot be opened and the elevator main power supply cannot be disconnected.

[0036] S4. After the abnormal fault is cleared, restore the elevator to normal operation. When abnormal data is detected, first determine if there is a fault. If not, maintain the elevator in normal operation; if there is a fault, perform emergency procedures.

[0037] Specifically, such as Figures 1 to 2 As shown, corresponding sensors for detecting door opening and closing are installed on the elevator car door and elevator door. For example, if an elevator door opening and closing detection sensor is installed on the elevator door and a car door opening and closing detection sensor is installed on the car door, then when abnormal opening and closing of the elevator door or car door is detected, the main controller can determine that the elevator has malfunctioned and further processing is required.

[0038] The elevator uses a mechanical-electro-friction type normally closed brake. A normally closed brake means that the brake engages when the machine is not in operation and disengages when the machine is running. When the elevator brakes, mechanical force causes the brake band to rub against the brake wheel, generating braking torque. When the elevator is running, electromagnetic force releases the brake; therefore, it is also called an electromagnetic brake. Based on the operating current of the coil that generates the electromagnetic force, elevators are classified as AC electromagnetic brakes and DC electromagnetic brakes. Because DC electromagnetic brakes offer smooth braking, are small in size, and reliable in operation, they are commonly used in elevators; therefore, the full name of this type of brake is normally closed DC electromagnetic brake. The working principle of the brake: When the elevator is stationary, no current flows through the coils of the traction motor and the electromagnetic brake. At this time, because there is no attraction between the electromagnet cores, the brake shoes, under the pressure of the brake spring, hold the brake wheel tightly, ensuring that the motor does not rotate. When the traction motor is energized and rotates, the coil in the brake electromagnet is simultaneously energized, the electromagnet core is quickly magnetized and attracted, driving the brake arm to exert force on its brake spring, the brake shoes open, and completely disengage from the brake wheel, allowing the elevator to run. When the elevator car reaches the desired stop, the traction motor is de-energized, and the coil in the brake electromagnet is also de-energized at the same time. The magnetic force in the electromagnet core quickly disappears, and the core, under the action of the brake spring, resets through the brake arm, causing the brake shoes to hold the brake wheel again, and the elevator stops working.

[0039] Therefore, brake testing requires checking whether the braking and holding functions are working properly. For example, installing an opening / closing detector, such as an infrared sensor or displacement sensor, on the brake arm can detect whether the brake arm opens and closes normally, such as whether it closes completely or opens completely, and whether it immediately performs braking or holding action upon power-on / off, thus determining whether the brake is working correctly. Another example is installing a power-on / off detector at the brake's electromagnet, such as a voltage / current sampling resistor or other structure that performs the same function, to detect whether the electromagnet is properly powered on and off, providing baseline data for determining whether the brake is working properly. Furthermore, a temperature sensor and a rotation direction detector can be installed on the brake to monitor the operating temperature in real time. Abnormal temperatures indicate a brake malfunction requiring timely repair. The rotation direction of the wheel also needs to be coordinated with the elevator's vertical movement; therefore, detecting the rotation direction of the wheel can also determine whether the brake is working properly.

[0040] Furthermore, in addition to inspecting the elevator doors, car doors, and brakes, the position of the elevator car can also be used to determine if there is any abnormality. If the car is detected to repeatedly stop at the same floor multiple times, it indicates that the elevator may be malfunctioning.

[0041] During the monitoring of elevator doors, car doors, car position, and brakes, corresponding possible abnormal events can be preset to determine elevator malfunctions. Specific events include:

[0042] 1. If the car door opens and closes m times or more without human intervention, with the opening gap less than x and the opening interval within y, an abnormal fault is identified. Here, m, x, and y are preset thresholds. For example, m could be 5, x 4mm, and y 25 seconds. This means that if the car door opens and closes 5 times or more without human intervention, with the opening gap less than 4mm and the opening time within 25 seconds, the elevator is malfunctioning and requires repair or maintenance. The threshold data is set according to the elevator specifications and relevant standards.

[0043] 2. If the elevator car is detected to repeatedly stop at the same floor a preset number of times (n times or more), an abnormal fault is determined to have occurred; where n is a preset threshold. For example, if n is 3, it means that if the elevator car repeatedly stops at the same floor 3 times or more, it indicates that the elevator is malfunctioning and requires assessment and maintenance.

[0044] III. If it is detected that the opening and closing of the brake are out of sync, not fully opened or not fully closed, it is determined that an abnormal fault has occurred. When the power is cut off or powered on, the brake needs to synchronously perform the action of braking closing or opening. If it cannot act synchronously, the function of the brake may be faulty and maintenance is required; or if the opening and braking closing actions are incomplete, the elevator cannot be completely fixed, which poses a risk to elevator operation and requires maintenance.

[0045] Therefore, if any abnormality of the above data is found during the self-monitoring process, the general controller needs to take emergency treatment in time. In order to avoid car top rushing or bottom squatting caused by sudden power failure, the elevator needs to be driven to the top floor or the bottom floor first and fixed there, so as to avoid accidents. How to determine whether the elevator should run upward or downward depends on the load of the elevator. Specifically, the method for determining the elevator load is as follows:

[0046] Let the weight of the car be P, the counterweight mass of the elevator be M, the car load be Q, and the balance coefficient be K (the specification describes the source of K), then:

[0047] When M > P+K*Q, the elevator runs to the top floor;

[0048] When M < P+K*Q, the elevator runs to the bottom floor.

[0049] The car load Q in the car needs to be monitored by a real-time pressure sensor arranged at the rope head position in the machine room, that is, the car load can be analyzed by detecting the pressure generated by the car through the pressure sensor. The balance coefficient K is obtained according to the effective value measured by the inspection and testing institution, and pre-input into the general controller of the present embodiment, and then the emergency operation direction of the elevator is determined according to the real-time load of the car and the balance coefficient K of the elevator.

[0050] After the elevator runs to the set position, it is necessary to judge the effectiveness of the brake. There are two ways to judge the effectiveness here: one is manual judgment, which is also determined based on various detection data; the second is that the general controller collects the working data of the brake, analyzes whether the brake is effective, and notifies the data terminal of the analysis result, that is, notifies the staff. After the elevator runs to the set position, the staff can carry out rescue treatment in time. If the brake is in an effective state, the main power supply of the elevator can be disconnected to make the brake further fix the elevator, and then the staff open the elevator landing door and the car door to complete the rescue; if the brake is in an invalid state, the general controller will control that the elevator landing door is not allowed to be opened or the main power supply of the elevator is disconnected to disconnect the safety circuit, and rescue needs to be carried out through other methods, so as to avoid accidents caused by the brake being unable to properly fix the elevator car when the power is cut off.

[0051] In addition, in this embodiment, upon detecting an anomaly and simultaneously moving the elevator to the top or bottom floor, the main controller can also initiate an emergency call via the elevator's communication device to notify passengers of the malfunction or danger, preventing accidents caused by passengers being unable to call for help in time. Furthermore, this embodiment can also be equipped with an alarm device; that is, when an anomaly occurs, the alarm device can notify others of the elevator malfunction through sound and light warnings.

[0052] This embodiment aims to provide safety protection for elevators by enabling self-monitoring of dangerous or abnormal states and providing additional braking devices to prevent abnormal elevator movement. By adding a braking device in addition to the elevator's brake, safety can be guaranteed even in extreme dangerous situations where the elevator's braking and traction systems completely fail. This embodiment can automatically interconnect dangerous state, location information, and equipment information to rescue and monitoring terminals. The main controller can achieve this by using existing communication devices, achieving the goal of "ensuring the safety of people and property in the first instance and intelligently notifying rescue and monitoring departments in the second instance." Furthermore, this embodiment is applicable to different types of elevators, especially older elevators with aging components and insufficient safety protection devices, which urgently need to be retrofitted. It has broad application prospects, is easy to install, highly reliable, and can identify various abnormal states, greatly improving the safety of elevator operation, especially in abnormal states.

[0053] Example 2:

[0054] This embodiment provides a multi-functional detection system for elevators in hazardous conditions, such as... Figures 1 to 2 The system includes a main controller, a brake detection device, a door detection device, a car detection device, an alarm device, and an emergency stop device. All of these devices are connected to the main controller via signals. The brake detection device detects the operating data of the elevator's brakes; the door detection device detects the operating data of the elevator doors and car doors; and the car detection device detects the load and position data of the car. The main controller uses the received data from the brake, door, and car detection devices to determine if the elevator is operating normally. If an abnormal malfunction occurs, the alarm device issues a warning, and the emergency stop device is activated to secure the elevator car.

[0055] In this embodiment, the emergency stop device can be a clamping clamp or other structure used for elevator stopping. It can be installed on the top of the car to stop the elevator in an emergency by clamping the steel wire rope. Alternatively, it can be installed on both sides of the elevator and stop the elevator in an emergency by cooperating with the rails in the elevator shaft. The operation of the emergency stop device is controlled by the main controller. When the elevator is in a safe operating state, the emergency stop device does not need to work, which can avoid damage caused by prolonged operation.

[0056] like Figures 1 to 2 As shown, the brake detection device in this embodiment includes an opening / closing detector, a temperature sensor, a rotation direction detector, and a power on / off detector. Specifically, the opening / closing detector can be an infrared sensor, a displacement sensor, or other device capable of detecting the distance between two objects, and is installed on the two brake arms of the brake. This allows it to detect the opening and braking states of the brake arms, including asynchronous opening and braking, incomplete opening, or incomplete braking. The temperature sensor can be installed on the electromagnet or brake arm of the brake to detect the operating temperature of the brake. The rotation direction detector can be installed on the brake wheel or electromagnet of the brake, and can determine the brake's operation and the elevator's running direction by observing the direction of the current on the electromagnet or the rotation direction of the brake wheel. The power on / off detector detects the on / off state of the brake's electromagnet, thereby detecting whether the brake's operation is normal. The opening / closing detector, temperature sensor, rotation direction detector, and power on / off detector are all existing technologies.

[0057] like Figures 1 to 2 As shown, the door detection device in this embodiment includes an elevator door open / close detection sensor, a car door open / close detection sensor, a distance detection sensor, and a timer. Specifically, the elevator door open / close detection sensor and the car door open / close detection sensor are both open / close sensors that detect whether the elevator door and car door are open. They can be installed on the elevator door and car door to determine whether the elevator door and car door have been opened abnormally or the number of times they have been opened. The distance detection sensor can be optionally installed on the elevator door and car door to detect the distance between the car door panels and the distance between the elevator door panels, thereby determining whether the elevator door or car door has been opened abnormally. The timer is also installed on the elevator door or car door to calculate the time between the opening and closing of the car door and the elevator door. The elevator door open / close detection sensor, the car door open / close detection sensor, the distance detection sensor, and the timer are all existing technologies.

[0058] like Figures 1 to 2As shown, the car detection device in this embodiment includes a pressure sensor and a laser rangefinder. The laser rangefinder can be optionally installed in the elevator machine room to detect the distance between the car and the machine room, thereby determining the car's position. The pressure sensor is installed at the end of the steel wire rope located in the machine room and can detect the load on the car. Both the laser rangefinder and the pressure sensor are existing technologies.

[0059] The working principle of this embodiment is as follows: the brake detection device detects the working status of the elevator brake in real time, the door detection device detects the working status of the elevator door and car door in real time, and the car detection device detects the working status of the car in real time. All detected working data are transmitted to the main controller, which monitors and analyzes them. When abnormal data is detected, the main controller controls the elevator to run to the top or bottom floor according to the elevator load, so that the emergency stop device clamps and fixes the elevator car. In addition, it determines whether the elevator brake is effective. If it is effective, the car door can be opened or the main power supply of the elevator can be disconnected for rescue or maintenance. If it is ineffective, the elevator safety circuit cannot be disconnected, and other methods are required for rescue or maintenance.

Including the following methods: Obtain elevator operating data; The elevator's operating data includes the operating data of the car doors, the position data of the car, and the operating data of the brakes. Based on the acquired elevator operating data, abnormal malfunctions of the elevator are identified, and the elevator is controlled to run to the top or bottom floor according to the load of the car. After the elevator runs to the top or bottom floor, the car is fixed by the emergency stop device pre-installed in the elevator. Determine the effectiveness of the elevator's brake; if the brake is effective, the elevator is in a state where the elevator landing door can be opened and the elevator main power supply can be disconnected; if the brake is ineffective or no determination of brake ineffectiveness is made, the elevator is in a state where the elevator landing door cannot be opened and the elevator main power supply cannot be disconnected. Once the abnormal fault is cleared, the elevator will return to normal operation. If abnormal data is detected, first determine if there is a fault. If not, maintain normal operation of the elevator. If there is a fault, take emergency measures. By installing corresponding sensors to detect door opening and closing on the elevator car door and elevator door, and installing a car door opening and closing detection sensor on the car door, when abnormal opening and closing of the elevator door or car door is detected, the main controller will determine that the elevator has malfunctioned and further processing is required.

The emergency running direction of the elevator is then determined based on the real-time load of the car and the balance coefficient K of the elevator. After the elevator is moved to the designated position, the effectiveness of the brake needs to be checked. The operating data of the brake collected by the main controller is analyzed to determine whether the brake is effective, and the analysis results are notified to the data terminal. If the brake is effective, the main power supply of the elevator is disconnected to activate the brake and further secure the elevator. Then, the staff can open the elevator door and car door to carry out the rescue.
