Embodiment 1

[0060] Such as Figure 1-2 As shown, step 100 is executed, the collector 210 collects the operation data of the coal mill 200 and sends it to the collection module 220 . Step 110 and step 120 are executed sequentially, and the acquisition module 220 screens and analyzes the real-time data of the coal mill 200 sent by the collector 210, and generates real-time operating data and alarm data (including the time, place, and occurrence of the abnormality) according to the operating data. Such problems, etc.), the module 220 summarizes the historical operating parameters of the coal mill 200, generates a curve, makes a historical parameter report, and makes the alarm data into an alarm parameter report. Step 130 is executed, and the collection module 220 saves the real-time operation data, alarm data, historical parameter report and alarm parameter report in the local memory in the storage module 230 .

[0061] Steps 140 and 150 are executed sequentially, and the real-time operatio...

Embodiment 2

[0063] Such as image 3 As shown, No. 1 collector 211, No. 2 collector 212, No. 3 collector 213 and No. 4 collector 214 are installed in the control cabinet 215. No. 1 collector 211 collects the operation data of No. 1 coal mill (including Coal volume, actual output of the system, vibration value, loading pressure, main motor power and current and voltage, speed of separator, power and current and voltage of main motor of powder separator, oil temperature of lubricating oil station, temperature of grinding roller, temperature of thrust tile of reducer , the opening and closing degree of various electric control valves of the mill, the sealing air volume, the temperature of the primary air entering the mill, the temperature of the mill outlet and the water spray volume) and transmit it to the acquisition module 220. The No. 2 collector 212 collects the operation of the No. 2 coal mill Data (including coal input, actual output of the system, vibration value, loading pressure, ma...

Embodiment 3

[0067] Such as Figure 4 As shown, the collectors used to collect real-time operation data of coal mills are all integrated in the control cabinet 215, and the control cabinet 215 collects the No. 1 coal mill 201, No. 2 coal mill 202, and No. 3 coal mill collected by the collector. The real-time operation data of coal mill 203 and No. 4 coal mill 204 (including coal input amount, actual output of the system, vibration value, loading pressure, main motor power and current and voltage, speed of classifier, power and current and voltage of main motor of classifier , lubricating oil station oil temperature, grinding roller temperature, reducer thrust tile temperature, opening and closing degree of various electronic control valves of the mill, sealing air volume, primary air entering the mill temperature, mill outlet temperature and water spray volume, etc.), and through The RS485 communication interface sends to the acquisition module 220. The acquisition module 220 screens and ...

Abstract

The invention provides a coal mill remote monitoring system and method. The method includes collecting the operation data of the coal mill, screening and analyzing the operation data, generating a real-time operation data table, adopting a dual storage method to save the real-time operation data table, and adopting an encryption method Upload data to the cloud storage, call the data in the cloud storage and display the running status. Users can monitor multiple units with a set of monitoring terminals. At the same time, the dual storage method can avoid the loss of cloud storage data when there is no network, which affects the terminal data call. The two storage methods protect each other and improve the reliability of the system. sex.

Description

technical field [0001] The invention relates to the technical field of remote monitoring of important equipment in thermal power generation enterprises, in particular to a remote monitoring system and method for coal mills. Background technique [0002] Coal mill is a machine that breaks coal and grinds it into coal powder. It is an important auxiliary equipment for pulverized coal furnace and an indispensable equipment for large steel mills, thermal power plants and cement plants. The structure and manufacture of the coal mill are relatively complicated, and the maintenance cost is relatively high. Daily maintenance is required, which consumes a lot of manpower and material resources. Due to the possibility of manual inspection, it is easy to cause major safety hazards. Therefore, the coal mill is monitored through the monitoring system. The running of testing was brought up on the agenda. [0003] In the prior art, the patent document with the publication number CN2023062...
