The vibration sensor 15 can detect elevator vibration. The mounting plate 1 is bolted to the top of the elevator car, allowing the device to detect elevator information through multiple sensors. In this embodiment, a mounting bracket 5 is fixedly mounted on the bottom of the data acquisition box 2, and a fan 6 is fixedly mounted on the bottom of the mounting bracket 5. The top of the mounting plate 1 has multiple threaded holes. The mounting plate 1 is bolted to the top of the elevator car. The top of the mounting plate 1 is equipped with a power supply cable. The data acquisition box 2, the acquisition sensor group 3 and the fan 6 are electrically connected to the power supply.

[0025] In this embodiment, the data acquisition box 2 is electrically connected to the data processing module 7, which is electrically connected to the microcontroller 16, the data storage unit 17, and the data processing algorithm 18.

[0026] In this embodiment, the wired transmission interface 19 is located on top of the data acquisition box 2. The wired transmission interface 19 and the wireless transmission module 20 are used for data transmission. The microcontroller 16 is a 32-bit ARM Cortex-M4F controller with a main frequency of 168MHz and rich ADC channels and communication interfaces. The microcontroller 16 receives analog and digital signals from the sensor group, amplifies, filters, samples, and digitizes these signals, converting the acquired raw data into standard digital signals. The data storage unit 17 includes 16MB of Flash memory and 8MB of SRAM memory. The Flash memory is used to store the acquired data and preset parameters, and the SRAM memory is used to temporarily store data during the microcontroller's processing to ensure data integrity and security. In this embodiment, the data processing module 7 is electrically connected to the data transmission module 8 and to the sensor group 3. In this embodiment, the microcontroller 16 is used to process data, and the data storage unit 17 is used to store data.

[0027] The implementation principle of a villa elevator data acquisition device in this embodiment is as follows: a data verification unit and a data fusion analysis unit are set in the data processing module 7; the data verification unit is electrically connected to the acquisition sensor group and uses multiple verification algorithms, including parity check and cyclic redundancy check (CRC), to perform real-time verification on the raw data collected by each sensor. When an abnormal data is detected, an alarm is immediately triggered and the abnormal data is marked; the data fusion analysis unit receives data from multiple sensors and uses data fusion algorithms such as Kalman filtering algorithm and DS evidence theory to analyze and process the multi-source data; for example, by combining the data from acceleration sensor, displacement sensor and vibration sensor, the data fusion analysis can determine whether the vibration during elevator operation is caused by abnormal mechanical failure, thereby improving the accuracy and reliability of the data;

[0028] The microcontroller 16 has a pre-stored sensor collaborative working strategy program. When the elevator starts, the microcontroller 16 controls the sensor group 3 to enter the collaborative working mode according to the preset strategy. For example, during the elevator's acceleration phase, the acceleration sensor 9, current sensor 13, and voltage sensor 14 work together. The acceleration sensor 9 monitors the elevator's acceleration changes, while the current sensor 13 and voltage sensor 14 monitor the current and voltage fluctuations of the motor. The microcontroller 16 analyzes the data from the three sensors to determine whether the elevator's power system is operating normally. During the elevator's leveling phase, the displacement sensor 10 and the door status sensor 12 work together. The displacement sensor 10 accurately monitors the elevator's position, while the door status sensor provides feedback on the elevator door's opening and closing status, ensuring that the elevator levels accurately and the doors open and close normally.

[0029] The device can cool the sensor group 3 through the fan 6 below to prevent the temperature inside the data acquisition box 2 from being too high. The air filter 4 can filter dust. The vibration sensor 15 can detect the vibration of the elevator. The mounting plate 1 is installed on the top of the elevator car with bolts, so that the device can detect elevator information through multiple sensors.

[0030] Accelerometer 9 is a triaxial MEMS sensor that can monitor the acceleration changes of the elevator in real time during operation, including vertical acceleration and deceleration and horizontal swaying. The measurement range is ±16g, the accuracy is up to 0.001g, and the sampling frequency is 1000Hz. It can accurately capture the tiny vibrations during elevator operation and provide data support for evaluating the elevator's ride quality and running stability.

[0031] The displacement sensor 10 is installed on the top of the elevator car, aligned with a fixed reflector at the top of the shaft. The sensor measures the distance change between the car and the top of the shaft by emitting laser light and receiving reflected light. The measurement accuracy is ±0.1mm, and the range is 0.5-5m. It can monitor the position and displacement changes of the elevator in real time, providing a basis for judging whether the elevator is accurately leveled.

The temperature measurement range is -40℃ to +125℃ with an accuracy of ±0.5℃, and the humidity measurement range is 0-100%RH with an accuracy of ±3%RH, providing data for assessing the environmental comfort in the car.

[0033] The door status sensor 12 uses a Hall effect sensor. When the door is closed, the sensor generates a signal; when the door is open, the signal disappears. By monitoring these signals, the opening and closing status of the elevator door can be determined in real time, and door malfunctions, such as the door not being fully closed or unable to open normally, can be detected in time.

[0034] The current sensor 13 is a Rogowski coil sensor, which is fitted onto the power supply line of the elevator motor. This sensor can monitor the current change of the motor in real time, with a measurement range of 0-100A and an accuracy of ±1%. It provides data for judging the operating status and load of the motor, and can provide timely warning of motor failure when the current is abnormal.

[0039] The microcontroller 16 has a built-in data processing algorithm 18 to analyze and process the collected data, including data filtering, feature extraction, and outlier detection. For example, by performing spectrum analysis on acceleration data, vibration frequency characteristics can be extracted to determine whether the elevator is running smoothly; by comparing current data with a preset current threshold, it can determine whether the motor is overloaded.
