Description

Technical Field

[0001] This utility model relates to the field of mining air compressor technology, and in particular to a mining air compressor control system. Background Technology

[0002] An air compressor is a device used to compress air and is widely used in mine ventilation, drainage, and other systems. Traditional air compressor operation relies primarily on manual operation and lacks intelligent control methods, resulting in the following shortcomings:

[0003] 1. Excessive Reliance on Manual Operation: Traditional air compressors rely on manual intervention for start-up and shutdown. Operators must rely on experience to judge air demand and manually start and stop the equipment. This method is not only inefficient but also prone to frequent start-ups and shutdowns due to improper operation, accelerating equipment aging and increasing maintenance costs. Furthermore, due to the lack of real-time monitoring and intelligent control, air compressors are prone to overpressure and underpressure issues during operation, leading to accelerated equipment wear, shortened equipment lifespan, and increased equipment replacement frequency.

[0004] 2. High energy consumption: Traditional air compressors cannot dynamically adjust their operating status according to actual air demand, resulting in a significant waste of electricity. Especially during peak electricity consumption periods, the operating costs of air compressors increase significantly.

[0005] 3. Lack of remote control and fault early warning: Traditional air compressor systems lack remote control functions, and equipment operating status, energy consumption data, fault information, etc. cannot be obtained in real time, resulting in delayed fault handling and affecting the continuity and safety of mine production. Utility Model Content

[0011] In a preferred embodiment, the current monitoring unit is a clamp-on current transformer, the flow monitoring unit is a turbine flow meter, and the pressure monitoring unit is a piezoelectric sensor.

[0012] In a preferred embodiment, the Web service unit establishes a communication connection with the main control unit via the Modbus TCP protocol.

[0013] In a preferred embodiment, the storage unit employs a ring buffer structure for data storage.

[0014] A preferred embodiment further includes an air compressor drain control unit and a solenoid valve.

[0017] After adopting the above solution, the beneficial effects of this utility model are as follows:

[0018] 1.

Through the remote control module and the start-stop control unit of the main control module, the operating status of the air compressor can be remotely adjusted, so that the operating load of each air compressor is more balanced and the service life of the equipment is improved.

[0019] 2. This utility model enables the main control module's energy consumption acquisition unit to rationally regulate the operating status and operating time of each air compressor based on changes in air demand, in conjunction with the start / stop control unit, through the current monitoring unit, flow monitoring unit, and pressure monitoring unit on each air compressor, thereby avoiding unnecessary energy waste and reducing electricity costs.

[0020] 3. This utility model, through the remote control module in conjunction with the main control module and the current monitoring unit, flow monitoring unit and pressure monitoring unit installed on each air compressor, can accurately monitor the operating status of each air compressor. When an air compressor malfunctions, the staff can obtain the fault information in a timely manner through the remote control module, and adjust the operating status of the air compressor in a timely manner through the remote control module in conjunction with the main control module, so as to ensure the continuity and safety of production operations.

[0026] The present invention will now be further described in conjunction with the accompanying drawings and specific embodiments.

[0027] This embodiment provides a control system for a mining air compressor, such as... Figure 1 As shown, it includes multiple air compressors 1, a main control module 2, and a remote control module 3;

The current monitoring unit 11 is installed on the main cable 14 of the air compressor 1, and the flow monitoring unit 12 and the pressure monitoring unit 13 are installed on the outlet pipe of the air compressor 1.

[0029] The main control module 2 is equipped with a main control unit 21, an energy consumption acquisition unit 22, a data acquisition unit 23, and a start-stop control unit 24. The current monitoring unit 11, flow monitoring unit 12, and pressure monitoring unit 13 of each air compressor 1 are electrically connected to the main control unit 21. The energy consumption acquisition unit 22, data acquisition unit 23, and start-stop control unit 24 are electrically connected to the main control unit 21, and the start-stop control unit 24 is electrically connected to the main cable 14 of each air compressor 1.

[0030] The remote control module 3 is equipped with a Web service unit 31, a data processing unit 32, a storage unit 33, a display unit 34, and an alarm unit 35. The Web service unit 31 establishes a communication connection with the main control unit 21, and the data processing unit 32 is electrically connected to the Web service unit 31, the storage unit 33, the display unit 34, and the alarm unit 35 respectively.

[0031] This embodiment, by installing a current monitoring unit 11, a flow monitoring unit 12, and a pressure monitoring unit 13 on each air compressor 1, can monitor the operating status of each air compressor 1 in real time, including parameters such as current, gas flow rate, and pressure. This helps to promptly identify and address potential problems, ensuring the stable operation of the air compressor 1 and improving production efficiency.

[0032] In this embodiment, the energy consumption acquisition unit 22 on the main control module 2 can convert the current signal of each air compressor 1 into energy consumption data, and transmit it to the Web service unit 31 of the remote control module 3 through the main control unit 21. This allows the operator to obtain the operating energy consumption information of each air compressor 1 and adjust the operating status of the air compressor 1 accordingly. The data acquisition unit 23 records the cumulative operating time of each air compressor 1. Combined with the start / stop control unit 24, this allows the operator to remotely start and stop the air compressor 1, improving the flexibility of use, avoiding the impact of frequent and erroneous start / stop operations on the air compressor 1, and thus extending its service life. The display unit 34 can be a large-screen monitor or a computer display screen.

[0033] In this embodiment, the remote control module 3 establishes a communication connection with the main control unit 21 through the Web service unit 31, realizing remote control of the air compressor 1. The data processing unit 32 processes and analyzes the collected data. When an anomaly or potential fault is detected, the display unit 34 and alarm unit 35 can promptly remind the management personnel to take measures to improve the safety of use.

[0034] Furthermore, in this embodiment, the current monitoring unit 11 is a clamp-on current transformer, which offers high measurement accuracy and can measure current without disconnecting the circuit, facilitating data acquisition and subsequent maintenance. The flow monitoring unit 12 in this embodiment is a turbine flow meter, offering high real-time performance, accurate data acquisition, and strong anti-interference capabilities in its output signal. The pressure monitoring unit 13 in this embodiment is a piezoelectric sensor, which boasts high sensitivity, accurately reflects the outlet pipe pressure of the air compressor 1, and exhibits good reliability. Of course, other sensors can also be used in other embodiments.

[0035] Furthermore, in this embodiment, the Web service unit 31 establishes a communication connection with the main control unit 21 through the Modbus TCP protocol, ensuring rapid data transmission. This enables the remote control module 3 to obtain the operating status and operating parameters of each air compressor 1 in real time and efficiently through the main control module 2, ensuring the stability of operation.

[0036] Furthermore, the storage unit 33 in this embodiment adopts a ring buffer structure for data storage, which can reuse its storage space, enabling the storage unit 33 to continuously and efficiently store data within a limited storage space, thereby improving the continuity of production operations.

[0037] Furthermore, this embodiment also includes an air compressor water discharge control unit and a solenoid valve. The air compressor water discharge control unit is electrically connected to the solenoid valve and the main control unit 21, respectively. The solenoid valve is installed on the drain pipe of the air compressor 1, so that the operator can control the opening and closing of the solenoid valve through the remote control module 3 in conjunction with the main control unit 21, thereby realizing automatic water discharge of the air compressor 1, which is beneficial to improving the service life of the air compressor 1 and improving the continuity and safety of production operations.

[0038] Furthermore, the solenoid valve is a normally closed type, which automatically closes in the event of power failure or abnormal conditions, thus improving safety. The normally closed solenoid valve is also equipped with an overcurrent protection unit to prevent damage or fire hazards caused by excessive current.

[0039] Furthermore, it also includes a manual ball valve, which is installed on the drain pipe of the air compressor 1, allowing the operator to manually control the opening and closing of the drain pipe when necessary, making it more flexible in use.
