Description

Technical Field

[0001] The invention relates to the technical field of elevator safety, and in particular to a power-off floor memory system for an elevator. Background Art

[0002] In recent years, with the substantial increase in the use of elevators and the continuous increase in the use time of elevators, elevator failures have inevitably shown an increasing trend. During the operation of the elevator, power failures are inevitable. Once an elevator fails to power on abnormally, the consequences of an accident are very serious.

[0003] After the power is cut off, the elevator's emergency brake is activated to fix the car, and its position will remain at the current floor. It will not automatically level or move to other floors. When the elevator is between two floors, the elevator will also stay between the two floors and will not continue to move. This causes inconvenience in subsequent emergency rescue, and as time goes by, the safety of the internal personnel is more likely to be affected. In addition, in existing shopping malls and high-rise buildings, there are mostly multiple elevators running at the same time. After the power is cut off, different elevators are in different positions, which increases the time consumed for emergency rescue and brings further inconvenience to subsequent emergency rescue. For this reason, an elevator power-off floor memory system is provided. Summary of the invention

[0004] The purpose of the present invention is to provide an elevator power-off floor memory system to solve the problem in the above background technology that the location where the existing elevator stays after power failure easily increases the time consumed for subsequent emergency rescue and brings inconvenience to emergency rescue.

[0005] To achieve the above object, the present invention provides the following technical solution: an elevator power failure floor memory system, comprising:

[0006] Elevator master control system: used to control and receive elevator floor control data and control the movement of the entire elevator;

[0007] Driving control system: used to receive instructions from the elevator master control system and drive the elevator to perform displacement operations according to the instructions;

[0008] Collection system: used to collect data during the operation of the elevator and provide data support for the use of different systems;

[0009] Emergency power supply system: used for emergency use through the emergency power supply system after the elevator power is cut off;

[0010] Memory system: used for the elevator's own position coordinates and floor information, and after a power outage, the memory system is used to process and judge the elevator's operation.

[0011] Preferably, the elevator master control system includes a storage module, a door opening and closing module, a control panel, a floor indication and running direction module, the storage module is used to store floor information and the floor information of the elevator itself during operation, the door opening and closing module is used to control the opening and closing operation of the elevator door, the control panel is used for the user to output the floor information to be reached, and the floor indication and running direction module enables the elevator to determine the upward or downward direction of the elevator according to the floor where the elevator is located based on the corresponding floor indication information.

[0012] Preferably, the input end of the traction control system is electrically connected to the output end of the elevator master control system, and the traction control system includes a traction motor module for traction operation, a speed regulation module for controlling the elevator lifting speed, and a speed feedback module for monitoring speed changes.

[0013] Preferably, the memory system includes a memory recording module, a model building module, a coordinate judgment module, and a feedback recording module. The memory recording module is used to obtain the floor information where the elevator is running. The model building module establishes a three-dimensional coordinate model based on the floor coordinate data and information obtained by the acquisition system. The coordinate judgment module judges and compares the floor position coordinates of different power-off elevators based on the established three-dimensional coordinate model to obtain the coordinates of similar points. The feedback recording module feeds back the coordinate data in the final solution to the elevator master control system, and the elevator master control system controls the elevator to run to that point.

[0014] Preferably, the memory system also includes an adjustment preset module and an adjacent memory module. The adjustment preset module is used to pre-set the maximum difference between elevator floors. After the difference between floors reaches a preset value, the adjacent memory module is enabled. The adjacent memory module obtains the floor information and data of the adjacent power-off floor based on the elevator's own floor information, and outputs the adjacent memory coordinate data to the feedback recording module.

[0015] Preferably, the emergency power supply system includes a power monitoring module, a shunt transmission module, an early warning and reminder module and a power-off switching module, so that the power monitoring module is used to monitor the voltage and discharge of the emergency power supply in real time and obtain the power of the emergency power supply. The shunt transmission module is used to shunt the power to each system and module according to the power supply requirements of each system and module for emergency use. The early warning and reminder module is used to feedback signals and data to the elevator master control system through an alarm reminder after the power reaches the set reminder value, and then feedback to the terminal pan / tilt and equipment through Bluetooth and wireless data transmission to remind the user to charge and replace the operation; the power-off switching module is used to switch the power supply to the emergency power supply after the elevator is powered off, so that the emergency power supply can supply the required power for the elevator in an emergency state.

[0016] Preferably, the operation process of the memory system includes the following steps:

[0017] (1) Obtain data from the acquisition system;

[0018] (2) Obtain the location information of the elevators on the remaining floors;

[0019] (3) Establish three-dimensional coordinate models of floors in different elevators;

[0020] (4) Determine whether the point is greater than the preset value;

[0021] (5) Determine the similar coordinate points on different floors;

[0022] (6) Record the coordinate point;

[0023] (7) Feedback coordinate points to the master control system;

[0024] (8) The elevator moves to this point.

[0025] Preferably, in the memory system judgment step, the acquired coordinate points are rounded down.

[0026] Preferably, the acquisition system includes a weight sensor, a position sensor, a temperature sensor, a pressure sensor, a door lock sensor, a safety touch panel sensor, a leveling sensor, and a door opening and closing sensor.

[0027] Preferably, the elevator floor recording process includes the following steps:

[0028] S1, determine whether the elevator is running;

[0029] S2. When the elevator is running, information is entered through the storage module and the memory system;

[0030] S3, determining whether the power is off during the operation of the elevator;

[0031] S4. After the elevator loses power, the emergency power supply system is activated, and the memory system is activated to obtain the pre-recorded location of the elevator itself.

[0032] Compared with the prior art, the present invention has the following beneficial effects:

[0033] (1) In the present invention, before power failure, the floor where the elevator is running is recorded through a storage module and a relatively independent memory system. After power failure, power is provided by the emergency power supply system, and the memory recording module in the memory system can obtain the previous floor record. According to the different floors where different elevators are located, a three-dimensional coordinate model of the floor where different elevators are located is established through a model building module. Based on the floor coordinate model, maintenance and rescue personnel can quickly know the location of the elevator, which improves the convenience of finding the location of the elevator and shortens the precious rescue time.

[0034] (2) By adjusting the preset value pre-set in the preset module, it is determined whether the number of floors between different floor coordinates is greater than the preset value. If it is greater than the preset value, the elevator is sent to the floor rounded down through the adjacent memory module, and the floor coordinate point where the elevator is located is recorded through the feedback recording module, and then the point is fed back to the outside for the convenience of maintenance and rescue personnel. By setting up the emergency power supply system, the elevator can still perform a certain displacement process after power failure, which can avoid the problem of the elevator being located between floors, causing great difficulty in emergency rescue. When the data difference is less than the preset value, the elevators move closer to each other and stop at the floor with the same coordinate point height, which is convenient for subsequent personnel to concentrate on maintenance and rescue.

The door opening and closing module is used to control the opening and closing operation of the elevator door. The control panel is used for users to output the floor information they need to reach.

[0045] Collection system: used to collect data during the operation of the elevator and provide data support for the use of different systems. The collection system uses a number of sensors to monitor the operation status of the elevator, including a weight sensor that detects the number of people and load conditions in the elevator, a position sensor that monitors the specific position of the elevator in the shaft to ensure that the elevator accurately stops at the floor, a temperature sensor that monitors the temperature of the internal and external environment of the elevator to prevent equipment damage caused by excessive temperature, a pressure sensor that monitors the air pressure in the elevator shaft to ensure that the difference in internal and external air pressure is small and ensures smooth operation of the elevator, a door lock sensor that monitors the status of the elevator door lock to ensure the safe closing of the elevator door, a safety touch panel sensor that monitors the status of the elevator door lock to ensure the safe closing of the elevator door, a leveling sensor that detects whether the elevator car has accurately reached the target floor to ensure the leveling accuracy, and a door opening and closing sensor that detects the opening and closing status of the elevator door to prevent the elevator from starting when the door is not completely closed;

[0046] Emergency power supply system: used for emergency use through the emergency power supply system after the elevator is powered off. The emergency power supply system includes a power monitoring module, a shunt transmission module, an early warning and reminder module, and a power-off switching module. The power monitoring module is used to monitor the voltage and discharge of the emergency power supply in real time and obtain the power of the emergency power supply. The shunt transmission module is used to shunt power to each system and module according to the power supply requirements of each system and module for emergency use. The early warning and reminder module is used to feedback signals and data to the elevator master control system through alarm reminders after the power reaches the set reminder value, and then feedback to the terminal pan / tilt and equipment through Bluetooth and wireless data transmission to remind users to charge and replace operations; the power-off switching module is used to switch the power supply to the emergency power supply after the elevator is powered off, so that the emergency power supply can supply the required power for the elevator in an emergency state;

[0047] Memory system; used for the elevator's own position coordinates and floor location information, and after power failure, the memory system is used to process and judge the elevator operation. The memory system includes a memory recording module, a model building module, a coordinate judgment module, and a feedback recording module. The memory recording module is used to obtain the floor information where the elevator is running. The model building module establishes a three-dimensional coordinate model based on the floor coordinate data and information obtained by the acquisition system. The coordinate judgment module judges and compares the floor position coordinates of different power-off elevators based on the established three-dimensional coordinate model to obtain the coordinates of similar points. The feedback recording module feeds back the coordinate data in the final solution to the elevator master control system, and the elevator master control system controls the elevator to run to the point. The memory system also includes an adjustment preset module and an adjacent memory module. The adjustment preset module is used to pre-set the maximum difference between the elevator floors. After the difference between the floors reaches the preset value, the adjacent memory module is enabled. The adjacent memory module obtains the floor information and data of the adjacent power-off layer based on the elevator's own floor information, and outputs the adjacent memory coordinate data to the feedback recording module;

[0048] The elevator floor recording process includes the following steps: S1, determine whether the elevator is in operation; S2, record the floor information where the elevator is operating through the storage module and the memory system; S3, determine whether the power is off during the operation of the elevator; S4, after the elevator is powered off, enable the emergency power supply system, and enable the memory system to obtain the floor information and the location of the elevator itself;

[0050] Among them, in the memory system judgment step, the coordinate point obtained is rounded down;

[0051] Before power failure, the storage module and the relatively independent memory system record the floor where the elevator is running. After power failure, the emergency power supply system provides power, and the memory module in the memory system can obtain the previous floor record. According to the different floors where different elevators are located, the three-dimensional coordinate model of the floor where different elevators are located is established through the model building module. Based on the floor coordinate model, it is convenient for maintenance and rescue personnel to quickly know the location of the elevator, which improves the convenience of finding the location of the elevator.

[0052] By adjusting the preset value pre-set under the preset module, it is determined whether the number of floors between different floor coordinates is greater than the preset value. For example, if the preset value is 2, and the two floors are 12 and 5 respectively, the final data difference is 7, which is greater than the preset value. Then the elevator is sent to the floor rounded down through the adjacent memory module, and the floor coordinate point where the elevator is located is recorded through the feedback recording module, and then the point is fed back to the outside for the convenience of maintenance and rescue personnel. The advantage of this part is that by setting up the emergency power supply system, the elevator can still perform a certain displacement process after power failure, which can avoid the problem that the elevator is located between floors, resulting in great difficulty in emergency rescue;

[0053] When the data difference is less than the preset value, the elevators will move closer to each other and stop at the floor at the same coordinate point height, making it convenient for subsequent personnel to concentrate on maintenance and rescue.
