Description

Technical Field

[0001] This utility model belongs to the field of port grab monitoring technology, specifically relating to a port bulk material grab full life cycle monitoring device. Background Technology

[0002] Bulk grabs, especially those used in ports, typically face complex and variable operating environments and heavy workloads. These grabs require frequent closing, lifting, rotating, and transporting operations, placing extremely high demands on the stability and reliability of the equipment. Furthermore, due to the harsh and complex operating environment, such as impact, high temperatures, humidity, and corrosion, grab components are prone to wear, deformation, and even damage, thus affecting their operational efficiency and safety.

[0003] To avoid production interruptions and safety accidents caused by equipment failures, it is necessary to monitor the usage time, process status, tool condition, and surrounding environment from the moment the grab bucket is put into use on the dock. This allows for more accurate development of grab bucket maintenance plans. However, traditional maintenance methods often rely on manual inspection and experience-based judgment, making it difficult to accurately predict the timing and cause of equipment failures. To achieve real-time monitoring and fault early warning of the grab bucket's status, it is necessary to collect and analyze a large amount of operational data. This data includes the grab bucket's real-time closing status, number of opening and closing cycles, movement trajectory, and ambient temperature and humidity. Data analysis can help identify potential faults in a timely manner and take appropriate measures.

[0004] Therefore, in order to address the above problems, and to improve the service life of grab buckets and reduce maintenance costs, it is urgent to study a full life cycle monitoring device for port bulk material grab buckets. Summary of the Invention

[0005] The technical problem solved by this utility model is achieved through the following technical solution:

[0006] The port bulk material grab bucket full life cycle monitoring device includes a microcontroller, a remote transmission module, an internal temperature detection module, an external environmental temperature and humidity sensor, a grab bucket tilt sensor, a battery pack, and a Beidou-GPS dual-mode satellite positioning and navigation module;

[0007] The remote transmission module, the internal temperature detection module, the battery pack, and the Beidou-GPS dual-mode satellite positioning and navigation module are all connected to the processor development board of the microcontroller. The external environment temperature and humidity sensor is installed on the grab bucket closing limit plate, and the grab bucket tilt angle sensor is installed on one side of the grab bucket closing limit plate.

[0008] The external environment temperature and humidity sensor is a DHT11 digital temperature and humidity sensor; the grab bucket tilt angle sensor is an MPU6050; and the microcontroller is an STM32F103RET6.

[0009] Furthermore, it also includes a host computer. The processor development board of the microcontroller processes the information transmitted by the remote transmission module, the internal temperature detection module, the battery pack, and the Beidou GPS dual-mode satellite positioning and navigation module, and then transmits it to the host computer via the remote transmission module.

[0010] Furthermore, the remote transmission module adopts the EC200 4G remote transmission module.

[0011] Furthermore, the external environmental temperature and humidity sensor is protected by an aluminum alloy IP68 housing.

[0012] Furthermore, the microcontroller is mounted on the closing limit plate of the grab bucket.

[0013] Furthermore, the internal temperature detection module is installed next to the microcontroller core board inside the casing to monitor the temperature of the microcontroller core board at any time.

[0014] Furthermore, the battery pack is connected to and powered by a microcontroller, a remote transmission module, an internal temperature detection module, an external ambient temperature and humidity sensor, a grab bucket tilt sensor, and a Beidou-GPS dual-mode satellite positioning and navigation module.

[0015] The advantages and positive effects of this utility model are:

[0016] This invention can acquire real-time information such as the grab's closing status, number of opening and closing cycles, movement trajectory, and ambient temperature and humidity. Through data analysis, potential faults can be detected in a timely manner, thereby taking corresponding measures to reduce grab maintenance costs and extend the grab's service life.

[0022] like Figure 1 As shown, the port bulk grab bucket full life cycle monitoring device provided in this embodiment includes a microcontroller, a remote transmission module 3, an internal temperature detection module 5, an external environment temperature and humidity sensor 6, a grab bucket tilt sensor 7, a battery pack 8, and a Beidou-GPS dual-mode satellite positioning and navigation module 9.

[0023] The remote transmission module, the internal temperature detection module, the battery pack, and the Beidou / GPS dual-mode satellite positioning and navigation module are all connected to the processor development board 1 of the microcontroller. The external environment temperature and humidity sensor is installed on the grab bucket closing limit plate and is protected by an aluminum alloy IP68 shell. The grab bucket tilt sensor is installed on one side of the grab bucket closing limit plate. The battery pack is connected to and powers the microcontroller, the remote transmission module, the internal temperature detection module, the external environment temperature and humidity sensor, the grab bucket tilt sensor, and the Beidou / GPS dual-mode satellite positioning and navigation module.

[0024] The external environment temperature and humidity sensor is a DHT11 digital temperature and humidity sensor; the grab bucket tilt angle sensor is an MPU6050; and the microcontroller is an STM32F103RET6.

[0025] It also includes a host computer. The processor development board of the microcontroller processes the information transmitted by the remote transmission module, the internal temperature detection module, the battery pack, and the Beidou GPS dual-mode satellite positioning and navigation module, and then transmits it to the host computer via the remote transmission module.

[0026] Furthermore, the remote transmission module adopts the EC200 4G remote transmission module.

[0027] The microcontroller is installed on the closing limit plate of the grab bucket; the internal temperature detection module is installed next to the microcontroller core board inside the shell to monitor the temperature of the microcontroller core board at any time.

[0028] In this embodiment, the processor development board 1 is an STM32F103RET6, with its input terminals connected to the internal temperature detection module 5, the external ambient temperature and humidity sensor 6, the grab bucket tilt sensor 7, and the battery pack 8. The processor development board 1 also has a maintenance communication and charging interface 3, supporting a Type-C interface. The remote transmission module 3 has its input terminal connected to the output terminal of the processor development board 1 and receives data packets via a SIM card. The remote transmission module 3 also includes an antenna 4 for transmitting data packets. The internal temperature detection module 5 uses temperature data transmitted via a DHT11 sensor and sets a threshold to monitor the internal temperature of the device, automatically triggering an alarm when the temperature exceeds the rated value. The external ambient temperature and humidity sensor... A DHT11 sensor is used, led out from the main equipment and installed on the grab bucket closing limit plate to accurately transmit the temperature and humidity of the external environment and send the temperature and humidity data to the microcontroller. The module is encased in an aluminum alloy IP68 housing. The grab bucket tilt sensor uses an MPU6050. One grab bucket tilt sensor is installed on one side of the grab bucket closing limit plate. The opening and closing angle reference value is determined on-site, a threshold is set, and the controller is programmed. If the angle exceeds the specified threshold, the counter increments by one. The battery pack is used to power the equipment, with a DC current of 5A. A Beidou-GPS dual-mode satellite positioning and navigation antenna is used, which can be directly connected to Gaode Map, providing accurate positioning, stable signal transmission, and strong shielding and anti-interference capabilities.

[0029] It should be noted that during installation, the aluminum alloy IP68 housing of this device is fixed to the grab bucket by drilling and tapping, and the components are fixed inside the housing by drilling screws.

[0030] The internal temperature detection module, external ambient temperature and humidity sensor, and grab bucket tilt angle sensor sense and measure the internal temperature, external ambient temperature and humidity, and grab bucket tilt angle through sensing elements. The sensed physical quantities are then converted into analog output signals and transmitted to the processor development board's input pins for data reading. Location data is transmitted to the processor via BeiDou / GPS dual-mode satellite positioning. The processor development board internally converts the analog signals to digital signals using a digital-to-analog converter. Data calibration ensures accuracy, and filtering eliminates noise and fluctuations. The processed data is then analyzed to meet monitoring requirements. After data processing, the processor development board encapsulates the processed data into data packets and sends them to the remote transmission module. The data is then transmitted remotely via an antenna. The host computer (e.g., a computer-based remote monitoring center) receives the data packets, parses and processes them to obtain the required environmental or equipment parameters. This allows for remote monitoring via an app.

[0031] The processor in this embodiment has a powerful processor core, 128KB of flash memory, 20KB of SRAM static storage, and a 72MHz operating frequency, which can stably support the operation of the device. It is small in size, with few parts, making it easy to implement. It adopts an IP68 all-aluminum alloy shell, which has good sealing performance and eliminates concerns about water ingress. It is highly flexible, does not require power, has its own battery, and has a long battery life. The grab bucket can move freely during the grabbing process without being restricted by cables. It can support remote online monitoring, such as observing the working status of the grab bucket, battery capacity, ambient temperature and humidity, and the number of grabbing operations through a mobile APP, making data recording more convenient and accurate, and improving port work efficiency.

[0032] The grab tilt sensor used in this implementation is the MPU6050, a six-axis motion processing sensor integrating a three-axis accelerometer and a three-axis gyroscope. Integrating the accelerometer and gyroscope along three axes onto a single chip reduces the number of external components and simplifies the design. It provides digital output and can communicate with the microcontroller via I2C or SPI interfaces, ensuring stable data transmission. The microcontroller (i.e., the main processor) is an STM32F103RET6, equipped with three 12-bit ADCs and two 12-bit DACs, suitable for analog signals, with strong expandability and rich interfaces for future device function updates. This embodiment features fast temperature and humidity response using a DHT11, with a temperature response time typically of 2-5 seconds and a humidity response time of approximately 2 seconds, enabling rapid capture of environmental changes and timely data transmission. The device has few intermediate structures and the main chip consumes very little power, resulting in energy savings.
