[0057] As an indispensable vertical transportation tool in high-rise buildings, the safe operation of elevators is of paramount importance. Currently, elevator monitoring requires regular on-site inspections by personnel to check elevator operating parameters and determine the safety status of the elevator. This manual inspection method is inefficient and makes it difficult to promptly identify and eliminate potential safety hazards.

[0058] This invention aims to solve at least one of the technical problems existing in the prior art. To this end, this invention proposes an elevator monitoring device capable of monitoring the elevator's operation in real time, improving the efficiency of elevator monitoring, and thus enhancing the timeliness of monitoring.

[0059] Reference Figure 1 , Figure 1 A block diagram of the anti-interference device in an embodiment of the present invention is shown. In some embodiments, the elevator monitoring device 100 is connected to the elevator controller 200. The elevator monitoring device 100 includes: a power conversion module 101, a central processing unit 102, a data acquisition module 103, and a data transmission module 104. The power conversion module 101, the central processing unit 102, the data acquisition module 103, and the data transmission module 104 are all electrically connected.

[0060] The power conversion module 101 is connected to the power pin of the controller 200, the central processing unit 102 is connected to the power conversion module 101, the data acquisition module 103 is connected to the central processing unit 102, and the data transmission module 104 is connected to the central processing unit 102. The power conversion module 101 converts the working voltage input to the controller 200 into working power. The central processing unit 102 operates when receiving working power. The data acquisition module 103 collects the elevator's operating data in real time and transmits the operating data to the central processing unit 102. The data transmission module 104 transmits the operating data to the Internet of Things.

[0061] The power conversion module converts the input controller's operating voltage into the central processing unit's (CPU) operating power and transmits this power to the CPU, enabling it to function normally. A data acquisition module collects the elevator's operational data and transmits it to the CPU. The CPU then transmits this data to a data transmission module, which in turn transmits it to the Internet of Things (IoT). The IoT then displays the operational data on an app for monitoring personnel to view. By installing an elevator monitoring device and using its data acquisition module to collect elevator operation data, and its data transmission module to transmit this data to the IoT, the IoT displays the data on an app for operators to view. This allows for real-time monitoring of the elevator's operation, improving monitoring efficiency and timeliness.

[0062] In some embodiments, the power conversion module includes a DC / DC converter, the input of which is connected to a power supply pin, and the output of which is connected to a data acquisition module.

[0063] It should be noted that a DC / DC converter is a voltage converter that effectively outputs a fixed voltage after transforming the input voltage. In this embodiment, the DC / DC converter converts the elevator's operating voltage into a power supply adapted to the central processing unit.

[0064] Reference Figure 2 , Figure 2 A circuit schematic diagram of a DC / DC converter according to an embodiment of the present invention is shown. In some embodiments, the DC / DC converter includes: a first transistor, a first inductor, a first diode, a first capacitor, and a first resistor.

[0065] The collector of the first transistor is connected to the controller, and the base of the first transistor is grounded. One end of the first inductor is connected to the emitter of the first transistor, and the other end of the first inductor is grounded. The cathode of the first diode is connected between the emitter of the first transistor and the first inductor. One end of the first capacitor is connected to the anode of the first diode, and the other end of the first capacitor is grounded. One end of the first resistor is connected to the central processing unit, the anode of the first diode, and the first capacitor, and the other end of the first resistor is grounded.

[0066] In this embodiment, the DC / DC converter is a step-up / step-down type DC / DC converter. When the operating voltage of the elevator is higher than the operating power supply of the central processing unit, the operating voltage can be reduced and stabilized at the corresponding voltage value of the operating power supply by stepping down. When the operating voltage of the elevator is lower than the operating power supply of the central processing unit, the operating voltage can be reduced and stabilized at the corresponding voltage value of the operating power supply by stepping up.

[0067] It should be noted that the first transistor is Figure 2 Transistor Q1 and first inductor Figure 2 Inductor L1, the first diode is Figure 2 Diode D1 and the first capacitor in the middle Figure 2 Capacitor C1, first resistor Figure 2 The resistor R1 in the middle.

[0068] In some embodiments, the operating data includes: acceleration data, vibration data, noise data, and temperature data, and the data acquisition module includes: an acceleration sensor, a vibration sensor, a noise sensor, and a temperature sensor.

[0069] An accelerometer is installed on the elevator to collect the elevator's acceleration in real time, obtaining acceleration data. A vibration sensor is installed on the elevator to collect the amplitude of the elevator's vibration in real time, obtaining vibration data. A noise sensor is installed inside the elevator to collect the noise inside the elevator in real time, obtaining noise data. A temperature sensor is installed on the motor inside the elevator to collect the motor's temperature in real time, obtaining temperature data.

[0070] It should be noted that the acceleration sensor is installed on the main structure of the elevator, such as on the car or guide rail. The acceleration sensor collects acceleration data in real time during the operation of the elevator. It can be used to monitor the dynamic characteristics of the elevator during startup, braking and constant speed operation, and to determine whether the elevator has abnormal acceleration or deceleration, such as sudden stop or shaking.

[0071] Vibration sensors are installed in the elevator car, guide rails, or mechanical components, such as on the traction machine. Vibration sensors monitor the amplitude of vibrations during elevator operation and can be used to identify problems such as mechanical component wear, guide rail misalignment, and car resonance. Vibration amplitude is a key data point for assessing the smoothness of elevator operation.

[0072] Noise sensors are installed inside the elevator car, such as in the ceiling or walls. These sensors collect internal noise data during elevator operation and can be used to determine if abnormal noises, such as unusual sounds or whistling, are generated by components like the motor, door operator, and guide rails. This improves the passenger experience and can also be used to indicate mechanical malfunctions.

[0073] Temperature sensors are installed on or near the surface of the elevator's built-in motor, such as traction motors and door operator motors. They can be used to monitor motor temperature in real time, preventing overheating caused by overload, poor heat dissipation, etc., thus avoiding insulation aging, equipment damage, and even safety hazards such as fire risks.
