Those skilled in the art can understand the specific meaning of the above terms in this embodiment of the invention according to the specific circumstances.
[0032] In one embodiment of this utility model, such as Figures 1-3 As shown, an elevator operation speed monitoring device is provided, including a housing 1, a control box 2, a speed sensor 3, a buffer component, and an alarm 5. The control box 2 and the speed sensor 3 are both fixedly connected inside the housing 1. The alarm 5 is fixedly connected to the bottom side of the housing 1. Both the speed sensor 3 and the alarm 5 are electrically connected to the control box 2. The buffer component is disposed between the housing 1 and the speed sensor 3, and is connected to both the housing 1 and the speed sensor 3.
[0033] The control box 2 includes a control box body 21, a control panel 22 and a microprocessor. The control panel 22 is electrically connected to the microprocessor, and the speed sensor 3 and the alarm 5 are both electrically connected to the microprocessor.
[0034] The elevator operating speed monitoring device provided in this application has its housing 1 fixedly installed in the elevator car. A speed sensor 3 detects changes in the elevator's speed, and a microprocessor calculates the elevator's real-time speed through integration. The detection result is then sent to the control box 2. When the elevator speed exceeds a preset safety range, an alarm 5 emits an audible and visual alarm signal. This application features a simple structure, low cost, and easy installation, enabling real-time monitoring of the elevator's operating speed and effectively improving elevator safety.
[0035] In another embodiment of this utility model, the microprocessor of the elevator running status speed monitoring device is an ARM Cortex-M0.
[0036] In another embodiment of this utility model, a control button 23 is fixedly connected to the control panel 22 of the elevator running status speed monitoring device, and the control button 23 is electrically connected to the control panel 22.
[0037] In another embodiment of this utility model, the buffer component of the elevator operating status speed monitoring device is a sponge sheet 4, which is fixedly connected to the housing 1 and the speed sensor 3. The sponge sheet 4 reduces vibration and improves the detection accuracy of the speed sensor 3.
[0038] The speed monitoring process of the elevator operating status speed monitoring device in this application is as follows:
[0039] Initialization and Parameter Setting: Upon device startup, the ARM Cortex-M0 microprocessor first performs its own initialization, configuring internal registers and related functional modules. Simultaneously, through the control panel 22, the operator inputs key parameters such as the elevator's normal operating speed range and alarm thresholds into the microprocessor. These parameters are stored in the microprocessor's internal non-volatile memory as the basis for subsequent speed determination.
[0040] Real-time speed monitoring and data acquisition: During elevator operation, speed sensor 3 continuously monitors the elevator's speed and converts the speed signal into an electrical signal. These electrical signals are transmitted to the ARM Cortex-M0 microprocessor using a specific communication protocol, such as SPI (Serial Peripheral Interface) or UART (Universal Asynchronous Receiver / Transmitter). Because the ARM Cortex-M0 has fast data processing capabilities and an efficient communication interface, it can receive the signals from speed sensor 3 in a timely and accurate manner.
[0041] Data Analysis and Judgment: After receiving speed data, the ARM Cortex-M0 microprocessor analyzes it according to a preset algorithm. It compares the real-time speed data with the normal speed range pre-stored in its internal memory. For example, assuming the normal operating speed range of the elevator is set to 1-2 meters per second, if the speed data received by the microprocessor exceeds this range, it is determined to be an abnormal speed. The high-speed computing power of the ARM Cortex-M0 allows this analysis and judgment process to be completed in a very short time, ensuring real-time monitoring of the elevator's operating status.
[0042] Anomaly Handling and Alarm Triggering: Once the ARM Cortex-M0 microprocessor detects an abnormal elevator speed, it immediately sends a high-level or low-level signal to the alarm 5 via its general-purpose input / output (GPIO) interface to the control box 2, thereby triggering the alarm 5 to operate. Upon receiving the signal, the alarm 5 quickly emits a loud alarm sound to alert surrounding personnel to the abnormal elevator operation. Simultaneously, the microprocessor can also send the anomaly information to the remote monitoring center via the communication interface, enabling relevant personnel to take timely measures to ensure elevator safety.
[0043] In another embodiment of this utility model, a smoke alarm 6 is fixedly connected to the bottom side of the housing 1 of the elevator running status speed monitoring device. The smoke alarm 6 includes a smoke alarm body 61, a smoke sensor 62, a humidity sensor 63, a buzzer 64, and a control board 65. The smoke alarm body 61 is fixedly connected to the bottom side of the housing 1. The smoke sensor 62, the humidity sensor 63, and the buzzer 64 are all fixedly connected to the control board 65 and electrically connected to the control board 65. The control board 65 is fixedly connected to the smoke alarm body 61. The smoke sensor 62, the humidity sensor 63, and the buzzer 64 are electrically connected to the microprocessor. The smoke alarm 6 detects ambient particles through a smoke sensor 62. When smoke enters the sensing area of the smoke sensor 62, the smoke particles interact with the light inside the smoke sensor 62, causing the smoke sensor 62 to generate a change in electrical signal. This signal change represents the smoke concentration information and is sent to the control board 65. When the control board 65 determines that the smoke concentration exceeds the set alarm threshold, it sends a control signal to trigger the buzzer 64 to work. Upon receiving the signal, the buzzer 64 emits a loud alarm sound to alert people to potential dangers such as fires, thereby improving safety.
[0044] Humidity sensor 63 is used to monitor the humidity in the environment. It is usually based on the characteristics of humidity-sensitive materials. When the ambient humidity changes, the physical or chemical properties of the humidity-sensitive materials will change accordingly, which will cause the electrical parameters of humidity sensor 63 to change. Humidity sensor 63 converts this change in electrical parameters into an electrical signal to reflect the level of ambient humidity.
[0045] In another embodiment of this utility model, the smoke alarm body 61 of the elevator operation status speed monitoring device is fixedly connected to the bottom side of the housing 1. A clearance hole 66 is provided in the middle of the smoke alarm body 61. One end of the smoke sensor 62 is fixedly connected to the control main board 65, and the other end extends out of the clearance hole 66. The clearance hole 66 on the smoke alarm body 61 of the elevator operation status monitoring device provides a channel for smoke to enter. When smoke appears in the elevator car or its surrounding environment, the smoke can enter the smoke alarm 6 through the clearance hole 66. The portion of the smoke sensor 62 extending out of the clearance hole 66 will directly contact the entering smoke.
[0046] In another embodiment of the present invention, the smoke alarm 6 of the elevator running status speed monitoring device further includes a button battery 67, which is fixedly connected to the control main board 65 and electrically connected to the control main board 65.
[0047] In another embodiment of this utility model, the top of the smoke alarm body 61 of the elevator operating speed monitoring device is provided with a smoke inlet hole 68. The smoke inlet hole 68 is located on one side of the clearance hole 66. There are multiple smoke inlet holes 68, which are evenly arranged in a ring on the smoke alarm body 61, with adjacent smoke inlet holes 68 spaced apart. The smoke inlet hole 68 improves the smoke intake efficiency and also improves the accuracy of smoke detection.
[0048] In another embodiment of this utility model, a cooling fan 7 is fixedly connected inside the housing 1 of the elevator operating status speed monitoring device. The cooling fan 7 is located on the top of the housing 1 and is electrically connected to the microprocessor. The cooling fan 7 accelerates the airflow inside the housing 1 and removes heat from the housing 1, thereby improving the heat dissipation efficiency.
[0049] In another embodiment of this utility model, the side of the housing 1 of the elevator operating status speed monitoring device is provided with heat dissipation holes 11. Multiple heat dissipation holes 11 are provided and evenly distributed throughout the housing 1. Heat inside the housing 1 is carried away through the heat dissipation holes 11, improving heat dissipation efficiency.
[0050] The elevator operation speed monitoring device provided in this application detects elevator speed changes through a speed sensor 3. A microprocessor calculates the elevator's real-time speed using integration and sends the detection result to the control box 2. When the elevator speed exceeds a preset safety range, an alarm 5 emits an audible and visual alarm signal. This application features a simple structure, low cost, and easy installation, enabling real-time monitoring of elevator speed and effectively improving elevator operation safety.
