At the same time, the data sensed by the sensor module is received by the receiving module and transmitted to the transmission module. The data is transmitted to the elevator sensing system by the transmission line. Once an overload is detected, the processor installed in the device will immediately trigger the elevator to stop or other safety mechanisms to prevent safety hazards caused by overload. Considering that there will be errors during detection, an infrared detection module is embedded in the elevator floor. The infrared detection module It can detect the number or density of passengers in the elevator. Together with the sensing block, it can achieve accurate detection of elevator overload, preventing panic among people in the elevator due to errors.

The elevator overload detection device combines a variety of detection technologies and intelligent control, with high accuracy and reliability. At the same time, the perfect protection mechanism and rapid response capability ensure that the elevator can take safety measures in time to protect the safety of passengers when it is overloaded.

When people enter the elevator, the elevator floor 3 is squeezed, and the squeezing column 13 starts to apply pressure to the support spring 4. When the support spring 4 is under pressure, the induction block 18 embedded in the connecting plate 10 also starts to decline with the decline of the support spring 4. When the number of people in the elevator reaches the approved number, the induction block 18 will touch the corresponding sensor module 6 below. At the same time, the data sensed by the sensor module 6 is received by the receiving module 7 and transmitted to the transmission module 8. The data is transmitted to the elevator sensing system by the transmission line 9. Once an overload is detected, the processor 2 installed in the device will immediately trigger the elevator to stop or other safety mechanisms to prevent the safety hazards caused by overload. Considering that there will be errors during detection, an infrared detection module is embedded in the elevator floor 3. Block 12, the infrared detection module 12 will detect the number or density of passengers in the elevator, and cooperate with the sensing block 18 to achieve the accuracy of elevator overload detection, preventing panic among people in the elevator due to errors, and the connection between the screw 19 and the connecting port 16 enables the connecting plate 10 to be more safely fixed in the elevator bottom plate 3, preventing dangerous situations in the elevator operation due to loosening, and the design of the hexagonal nut 14 can more conveniently adjust, fix, repair and disassemble the extrusion column 13, and the fixing ring 17 can further fix the hexagonal nut 14 to prevent the loosening of the extrusion column 13 from causing safety hazards.

[0025] Embodiment 2

[0026] Based on the first embodiment, the solution in the first embodiment is further detailed in combination with the following specific working method, as described below:

[0028] The working process of the utility model is as follows:

[0029] When the elevator overload detection device is in use, the device body 1 is the main part of the whole device, which improves the overall stability. When people enter the elevator, the elevator floor 3 is squeezed, and the squeezing column 13 starts to apply pressure to the support spring 4. When the support spring 4 is under pressure, the induction block 18 embedded in the connecting plate 10 also starts to decline as the support spring 4 declines. When the number of people in the elevator reaches the approved number, the induction block 18 will touch the corresponding sensor module 6 below. At the same time, the data sensed by the sensor module 6 is received by the receiving module 7 and transmitted to the transmission module 8. The data is transmitted to the elevator sensing system by the transmission line 9. Once an overload is detected, the processor 2 installed in the device will immediately trigger the elevator to stop or other safety mechanisms to prevent safety hazards caused by overload. Considering that there will be errors during detection, an infrared detection module is embedded in the elevator floor 3. 12. The infrared detection module 12 will detect the number or density of passengers in the elevator. It can achieve the accuracy of elevator overload detection with the induction block 18 to prevent the panic of people in the elevator due to errors. The connection between the screw 19 and the connection port 16 allows the connection plate 10 to be more securely fixed in the elevator bottom plate 3 to prevent dangerous situations in the elevator operation due to looseness. The design of the hexagonal nut 14 can more conveniently adjust, fix, repair and disassemble the extrusion column 13. The fixing ring 17 can further fix the hexagonal nut 14 to prevent the loosening of the extrusion column 13 from causing safety hazards. The elevator overload detection device combines a variety of detection technologies and intelligent control, with high accuracy and reliability. At the same time, the perfect protection mechanism and rapid response capability ensure that the elevator can take safety measures in time when overloaded to protect the safety of passengers. This is the working process and working principle of the device.
