Description

Technical Field

[0001] The invention relates to the technical field of environmental monitoring, in particular to a collector with an additional GPRS module. Background Art

[0002] In environmental monitoring, the collector using GPRS module is an efficient data transmission method. The collector collects environmental parameters such as temperature, humidity, pressure, flow, etc. through field sensors and converts these data into digital signals. Subsequently, these data are sent wirelessly to the remote control center through the GPRS module. The GPRS module uses the mobile communication network to ensure the real-time and reliability of the data. This method not only simplifies the wiring, but also improves the flexibility and coverage of data transmission, making environmental monitoring more efficient and convenient.

[0003] The collector of GPRS module usually consists of GPRS communication module, data acquisition module, central controller, data processing module and data storage module. The central controller controls the GPRS communication module to connect with the remote device, and collects data through the information acquisition module. The collected data will be sent to the data processing module through the central controller to clean, filter and remove noise. The data processing module sends a signal to GPRS and transmits it to the connected remote device. At the same time, the central controller sends the data of the collection module to the storage module for storage. During use, the microcontroller transmits the data signal to the GPRS communication module and transmits the data to the remote control center. It is difficult to judge whether the data exceeds the normal value range. The remote control personnel need to check the displayed signals one by one, which leads to the judgment of whether the on-site environment is abnormal, which increases the judgment time and reduces the work efficiency. To this end, we propose a collector with an additional GPRS module. Summary of the invention

[0010] Preferably, the data storage module uses a solid state drive (SSD) as a core medium for data storage, and compresses and stores the stored data in a hardware compression manner using a Lempel-Ziv-Welch algorithm.

[0011] Preferably, in the alarm module, two thresholds are set for temperature, humidity, pressure and flow respectively, one is an upper threshold and the other is a lower threshold.

[0012] Preferably, the edge computing module is connected to the GPRS communication module via a high-speed interface.

The microcontroller retrieves the data stored in the date and sends the data to the remote control center for viewing through the GPRS communication module.

[0019] As a further limitation of the present invention, the data acquisition module is connected to the sensors at the scene through the analog signal structure, and the sensors include temperature sensors, humidity sensors, pressure sensors and flow sensors. The sensors transmit signals to the data acquisition module, and the received analog signals are converted into digital signals through the built-in analog-to-digital converter ADC; The data processing module uses the exponential extrapolation method to clean the acquired data, and uses the median filtering method to filter and remove noise from the cleaned data; The exponential extrapolation formula is: Y=a× e^bX; Where a represents the coefficient, b represents the growth / decay rate, which determines the speed at which Y changes with X.

The median filter formula is: g(x,y)=med{f(xk,yl),(k,l)∈W}; Where f(x,y) represents the pixel value of the original image at point (x,y), g(x,y) represents the pixel value at point (x,y) after median filtering, W is a two-dimensional window, which is an odd-sized area of ​​5*5, and med{.} represents the median operation, that is, for all pixel values ​​in window W, after arranging them in ascending order, the middle value is taken as g(x,y); The data storage module uses solid-state hard disk (SSD) as the core medium for data storage, and uses the hardware compression method of Lempel-Ziv-Welch algorithm to compress and store the stored data; In the alarm module, two thresholds are set for temperature, humidity, pressure, and flow, one is the upper threshold and the other is the lower threshold; The edge computing module is connected to the GPRS communication module through a high-speed interface; The user interaction module uses a CLI interface, allowing users to perform search operations through keyboard input.

The date entered by the user is interpreted using C language, and the command is verified to be valid or incorrect. YYYY-MM-DD is used to indicate the time when data is stored, where Y represents year, M represents month, and D represents day.

[0020] The specific implementation of this embodiment is as follows: The temperature, humidity, pressure and flow rate of the site are monitored in real time through various sensors on site. The data obtained by the sensor will be transmitted to the data acquisition module. The acquisition module converts the analog signal sent by the sensor into a digital signal through the analog-to-digital converter AC, and transmits the digital signal to the data processing module. The digital signal is cleaned by the exponential extrapolation method in the data processing module. The cleaned data is filtered and de-noised by the median filtering method to ensure the accuracy of the data, and the processed data is sent to the microcontroller MCU. The data is first sent to the alarm module through the microcontroller MCU, and compared with the upper and lower limit thresholds preset in the alarm module. If the upper and lower limit thresholds are not exceeded, the alarm module will generate an alarm. When the lower limit threshold is reached, the alarm module will only send a digital signal to the GPRS communication module, and send the signal to the remote control center through the TCP / IP channel for display. When the upper and lower limit thresholds are exceeded, the alarm signal value is sent to the remote control center at the same time as the digital signal is sent to remind the staff. Inserting the edge computing module between the alarm module and the GPRS communication module can speed up the data transmission speed and ensure the transmission efficiency. When the user views the historical records, enter the date in the "YYYY-MM-DD" format on the CLI interface, and use the obtained instructions to find the historical records of the day. At the same time, interpret it through C language to check the correctness of the command.
