This monitoring system utilizes Internet of Things technology to collect and process data and environmental parameters of key nodes of coal transportation equipment in ports. It uses composite intelligent sensors to collect and process the data, and then uploads it to the computer through wired (wireless) transmission methods to obtain real-time status information of equipment operation and environmental parameters. Through monitoring software, it analyzes the trend of equipment health deterioration and stores, queries, and statistics historical data. By analyzing the data, potential hazards can be predicted in advance, providing effective data support for equipment management. When the set parameters exceed the threshold, the system will automatically alarm in the monitoring room and send SMS alarms to relevant management personnel on their mobile phones. To achieve timely detection and elimination of equipment failures, minimize equipment losses, and ensure the safe operation of equipment.
In addition to monitoring parameters such as temperature measurement, vibration measurement, and axial displacement of the belt conveyor drum that we have currently installed, any important node of the entire coal conveying system can also be monitored in real time, such as the overturning machine, stacker, reclaimer, and ship loader. Regardless of the type of sensor (even if it is an analog output sensor not produced by our company), it can be connected to the system bus through the bus unit module and uploaded wirelessly or wired. The schematic diagram of the monitoring system for this project is as follows:

The technological innovation points of this system
1. Intelligent and composite vibration temperature sensor with digital output function. The intelligent composite vibration temperature sensor can simultaneously measure the effective value of vibration velocity and the Celsius temperature value. This sensor embeds a temperature sensor into a vibration acceleration sensor, as well as a signal conditioning chip, a microcomputer chip, and a bus output chip, to achieve functions such as charge conversion, amplification, filtering, one-time integration, effective value conversion, analog-to-digital conversion, and digital output. The main advantages of this sensor include strong anti-interference ability, high accuracy, stable performance, high reliability, low energy consumption, long-distance error free transmission, multiple synchronous data collection and reception of broadcast information on the bus. At the same time, the product also has independent intellectual property rights and can prevent virus infection and information leakage. 2. A bus unit module with analog input and digital output functions. The bus unit module converts various types of analog input signals into digital signals that can be directly connected to the bus. The main purpose of the module is to connect with sensors or analog signal conditioners, enabling them to have digital functions. For example, when the displacement sensor with analog output is connected to the bus unit module, it becomes a displacement sensor with digital output and can be directly connected to the bus for use. Similarly, the bus unit module can connect tens of thousands of types of sensors to the data bus. 3. A data collector with multiple buses. A multi bus data collector is an instrument that connects digital sensors with upper level buses or upper level computers, responsible for integrating and transmitting information between sensors and computers. The data collector has 3 input buses and 1 output bus. The input bus of the data collector can use different communication protocols according to the attached sensors or instruments. In data communication, optimize the underlying communication protocol to improve data transmission efficiency at the same baud rate. On the basis of improving communication efficiency, the bit error rate has been reduced. The output bus of the data collector can be directly connected to a computer, or connected to wireless data transmission devices for long-distance communication. It can also accept the management of the higher-level data collector, connecting multiple data collectors together to form a new data bus in the middle layer. 4. Develop multi bus data communication software. The main function of the communication software is to initiate inquiries (initiate communication) to the acquisition device at specified time intervals. Upon receiving the request, the acquisition device collects on-site data and sends it back to the communication software. The communication software then transmits the data in real-time to the upper computer software. 5. Develop upper computer application software. This software can display real-time data, store data (stored in SQL Server 2000 database), view historical data, draw historical curve graphs, query alarm data, summarize previous shift alarms, and set various parameters of the software by receiving data transmitted from the communication part. When an alarm occurs, this software can sound and display an alarm simultaneously. If the data exceeds the alarm value, the corresponding screen will flash yellow. If the sensor fails, the corresponding screen will flash yellow.

This monitoring system has a wide range of application markets
The significance of this monitoring system is that it can not only be used for online monitoring of equipment status in coal transportation ports, but also for online monitoring of equipment status in any other industrial industry. It can also be applied to process detection in industrial production lines and real-time collection of production process data. Real time monitoring of the width, thickness, and temperature of processed products can be achieved in the production process of steel, thereby improving product quality and optimizing the production process. This monitoring system can be used for industrial safety production management by embedding and equipping intelligent sensors into mining equipment, oil and gas pipelines, and mining equipment. It can sense the safety status information of workers, machinery equipment, surrounding environment, and other aspects in hazardous environments. It elevates the existing decentralized, independent, and single network supervision platform into a systematic, open, and diversified comprehensive network supervision platform, achieving real-time perception, accurate identification, quick response, and effective control. This monitoring system can perform environmental monitoring and energy management. The integration of this project's system with environmental protection equipment can provide real-time monitoring of various pollution sources and key indicators of pollution control in industrial production processes. Installing wireless sensor devices at the discharge outlets of key polluting enterprises can not only monitor the real-time discharge data of the enterprises, but also remotely close the discharge outlets to prevent sudden environmental pollution accidents. This monitoring system can be used for environmental monitoring in facility agriculture and online monitoring in animal husbandry, helping farmers to carry out refined and scientific production to improve resource utilization and economic benefits. This monitoring system can perform online monitoring of urban underground pipelines, such as monitoring and managing parameters such as pressure, flow rate, and gas leakage in urban water and gas pipelines, achieving digital urban management. This monitoring system can be used for status monitoring of large-scale national infrastructure, such as monitoring pressure and vibration parameters of water conservancy dams, vibration and stress parameters of bridges and culverts on highways and railways, to ensure the absolute safety of important livelihood facilities. Therefore, this project has a very broad market application prospect. Our company can tailor a device online monitoring system based on the Internet of Things for users according to their requirements, using the technology of this system. |
