Description

Technical Field

[0001] This utility model relates to an intelligent elevator weighing controller, and more particularly to an intelligent elevator weighing controller with wireless debugging function applied in the elevator field. Background Technology

[0002] The wireless electromagnetic induction load control system is a weighing and commissioning system designed and developed for the special installation environment of elevators with movable car bottoms. It measures weight by detecting the deformation of the car bottom rubber and realizes wireless control.

[0003] During the installation of the elevator weighing controller, under empty car conditions, the magnet needs to be attracted to the center position of the car bottom, with the mark facing down. The controller is then installed on the fixed bracket, and the fixed bracket is fixed on the bottom beam of the car at the position corresponding to the magnet, so that the sensing center indicated on the controller is directly aligned with the center position of the sensing magnet. It is essential to ensure that the mark on the magnet is strictly aligned with the mark on the controller, and that the controller and magnet are parallel.

[0004] In the above installation method, the original debugging method requires professional debugging personnel to enter the shaft and manually operate the equipment to complete the calibration process. Moreover, since the equipment is installed at the bottom of the car, the condition of the equipment cannot be directly observed or actively reported during normal elevator use. During the elevator movement, the elevator may accelerate or decelerate, and the sudden change in motor torque may cause inertial vibration of the car, which will cause the bracket of the elevator weighing controller to vibrate. After long-term use, the screws connecting the bracket to the weighing controller may loosen, causing the weighing controller to tilt and fail to maintain a parallel state with the magnet, thus affecting the use of the elevator weighing controller. Utility Model Content

[0005] The technical problem that this utility model aims to solve in view of the above-mentioned prior art is that vibrations occur during the movement of the elevator, which causes the support of the elevator weighing controller to vibrate, and may cause the elevator weighing controller to tilt, making it unable to maintain a parallel state with the magnet and affecting its normal use.

[0006] To address the aforementioned issues, this utility model provides an intelligent elevator weighing controller with wireless debugging capabilities. The controller includes a main body, a base, and a housing inserted into the upper part of the base. Cylinders are fixedly connected to the four corners of the base's inner bottom wall. A mounting plate is fixedly connected to the upper end of each cylinder. A Hall effect signal acquisition module, a data processing core, a Bluetooth signal module, a power drive module, and an alarm drive module are fixedly connected to the upper end of the mounting plate. An anti-vibration component is located at the lower end of the controller, comprising a universal joint fixedly connected to the lower end of the base. A damping plate and a positioning plate are fitted onto the outer surface of the universal joint. The positioning plate is fixedly connected to the base by multiple bolts. A support rod is located at the lower end of the universal joint, with a ball fixedly connected to the upper end of the support rod. The ball is located within the universal joint. Multiple hanging blocks are fixedly connected to the outer surface of the support rod, and a magnetorheological damper is rotatably connected within each hanging block. The upper end of the magnetorheological damper is rotatably connected to the lower end of the positioning plate. A support frame is fixedly connected to the lower end of the support rod.

[0007] In the aforementioned intelligent weighing controller for elevators with wireless debugging capabilities, the Hall effect principle can be utilized to indirectly detect changes in weight within the car by detecting the distance between the magnet and the Hall signal acquisition module. The device's status is then uploaded to a mobile phone via Bluetooth, eliminating the need for debugging personnel to enter the shaft to calibrate the device. This also enables the active status monitoring and reporting function, achieving wireless connectivity for device detection and control. Furthermore, an anti-vibration component is installed on the controller body. When the elevator vibrates, the vibration is absorbed by a shock-absorbing plate and a magnetorheological damper, effectively suppressing the vibration and tilting of the controller body caused by elevator vibration.

[0008] As a further improvement of this application, the front end of the base is drilled with multiple honeycomb through holes, and the upper end of the outer shell is fixedly inlaid with multiple convex lenses.

[0009] As a further improvement of this application, the shock-absorbing plate is located at the upper end of the positioning plate, and the shock-absorbing plate is fixedly connected to the positioning plate. The upper end of the shock-absorbing plate is in contact with the lower end of the base, and the shock-absorbing plate is made of rubber.

[0010] As a further improvement of this application, the cylinder, Hall signal acquisition module, data processing core, Bluetooth signal module and alarm drive module are all electrically connected to the power drive module, and the Hall signal acquisition module, Bluetooth signal module and alarm drive module are all electrically connected to the data processing core.

[0011] As another improvement of this application, multiple hanging blocks are arranged in a ring array around the outer surface of the support rod, and the upper end of the magnetorheological damper is spherical.

[0012] In summary, in practical applications, the distance between the magnet and the Hall element can be detected by the Hall signal acquisition module, indirectly detecting changes in weight within the car. The device status can be uploaded to a mobile phone via Bluetooth, enabling wireless connection for device detection and control. Debugging personnel do not need to enter the shaft to calibrate the device; instead, they can connect to the device wirelessly via Bluetooth to remotely operate it, achieving the purpose of calibration and debugging. Furthermore, when vibrations occur during elevator movement, multiple magnetorheological dampers provide buffering and protection, while vibration damping plates absorb the vibrations, giving the controller a vibration-resistant function and effectively suppressing the shaking and tilting of the controller caused by elevator vibrations.

[0021] The two embodiments of this application will be described in detail below with reference to the accompanying drawings.

[0022] First implementation method:

[0023] Figure 1 and Figure 2The following is illustrated: An intelligent elevator weighing controller with wireless debugging function includes a controller body, which includes a base 1. A housing 2 is inserted into the upper end of the base 1. Cylinders 3 are fixedly connected to the four corners of the inner bottom wall of the base 1. Those skilled in the art can select a suitable model of cylinder 3 according to actual needs, such as SCD50x100-100-LB. A mounting plate 4 is fixedly connected to the upper end of the cylinder 3. A Hall signal acquisition module 5, a data processing core 6, a Bluetooth signal module 7, a power drive module 8, and an alarm drive module 9 are fixedly connected to the upper end of the mounting plate 4. Multiple honeycomb through holes are drilled at the front end of the base 1, which can assist the vibration of the sound source at a specific vibration frequency to achieve the purpose of increasing the sound frequency. Multiple convex lenses are fixedly embedded in the upper end of the housing 2, which use the principle of light refraction to focus light and increase the local light intensity. The cylinder 3, Hall signal acquisition module 5, data processing core 6, Bluetooth signal module 7, and alarm drive module 9 are all electrically connected to the power drive module 8. The Hall signal acquisition module 5, Bluetooth signal module 7, and alarm drive module 9 are all electrically connected to the data processing core 6. The Hall signal acquisition module 5 introduces the change in magnetic flux into the data processing core 6 to complete the load identification. The output of the controller is connected to the elevator mainboard and provides load information to the mainboard through CAN, level signals, analog voltage signals, or analog current signals. After connecting to the mobile APP through the Bluetooth signal module 7, the device under the car can be operated wirelessly by the mobile phone. At the same time, this device provides a load alarm function. When in alarm state, the device will trigger the alarm drive module 9 to realize the transmission of audible and visual alarm information from inside the shaft to the outside.

[0024] When the controller is in use, the distance between the magnet and the Hall element can be detected by the Hall signal acquisition module 5, indirectly detecting changes in weight inside the car. The status of the device is uploaded to the mobile phone via the Bluetooth signal module 7, realizing wireless connection for device detection and control. The commissioning personnel do not need to enter the shaft to calibrate the device, but can connect to the device wirelessly via Bluetooth on their mobile phones to remotely operate the device, achieving the purpose of calibration and commissioning. Due to the concealed installation location of the controller, changes in device parameters may not be detected and corrected in time. Through the independent alarm drive module 9, the elevator management personnel can be greatly alerted in the shaft environment, forming a functional requirement for proactive status monitoring and reporting. The commissioning personnel can connect to the device via a WeChat mini-program on their mobile phones to remotely operate the device.

[0025] Second implementation method:

[0026] This embodiment adds a stabilization component to the first embodiment, while the rest remains the same as the first embodiment.

[0027] Figure 3 , Figure 4 , Figure 5 and Figure 6 The controller body is shown to have an anti-shake component at its lower end. This component includes a universal joint 10 fixedly connected to the lower end of the base 1. A damping plate 11 and a positioning plate 12 are fitted onto the outer surface of the universal joint 10. The positioning plate 12 is fixedly connected to the base 1 by multiple bolts. A support rod 13 is located at the lower end of the universal joint 10, and a ball 14 is fixedly connected to the upper end of the support rod 13. The ball 14 is located within the universal joint 10 and can slightly tilt within the universal joint 10 for angle compensation, thereby limiting the controller body. Multiple hanging blocks 15 are fixedly connected to the outer surface of the support rod 13, and a magnetorheological damper 16 is rotatably connected within each hanging block 15. Those skilled in the art can select a suitable model of magnetorheological damper 16 according to actual needs, such as C39-60. The upper end of the magnetorheological damper 16 is rotatably connected to the lower end of the positioning plate 12. The lower end of the support rod 13 is fixedly connected to the support frame 17. The damping plate 11 is located on the upper end of the positioning plate 12 and is fixedly connected to the positioning plate 12. The upper end of the damping plate 11 is in contact with the lower end of the base 1. The damping plate 11 is made of rubber. The damping plate 11 can effectively prevent vibration from being transmitted to the controller body, thereby effectively improving the stability of the controller body during use. Multiple hanging blocks 15 are arranged in a ring array around the outer surface of the support rod 13. The upper end of the magnetorheological damper 16 is spherical, which allows the magnetorheological damper 16 to be traction-shaken, thereby absorbing vibration force. The magnetorheological damper 16 can be connected to the data processing core 6 signal to adjust the damping force in real time and suppress low-frequency vibration.

[0028] During the elevator's up and down movement, the elevator car vibrates, causing the support frame 17 to vibrate. At this time, the vibration is absorbed by the damping plate 11, and multiple magnetorheological dampers 16 provide buffer protection. The ball 14 can tilt slightly within the universal ball joint 10 for angle compensation, thereby limiting the control unit body and giving the control unit body an anti-shake function, effectively suppressing the shaking and tilting of the control unit body caused by elevator vibration.

[0029] In light of current practical needs, the above-described embodiments adopted in this application are not limited to these. Any changes made within the scope of knowledge possessed by those skilled in the art without departing from the concept of this application still fall within the protection scope of this utility model.
