Description

Technical Field

[0001] The present disclosure relates to the technical field of automatic control, and particularly to an air compressor control system and method, device, and electronic equipment.

Background Art

[0002] With the development of industrial production, the application of air compressors has become increasingly widespread in various fields. As a device that converts mechanical energy into gas pressure energy, its main function is to provide a power source for various pneumatic devices. Therefore, while air compressors are an indispensable device in industrial production, with the improvement of industrial automation, the control of air compressors is also increasingly required to be higher.

[0003] Conventional air compressor control systems typically require on-site operation by an operator. When controlling an air compressor, real-time measurements from each compressor's sensors are uploaded only to the on-site programmable logic controller (PLC) of that compressor. The PLC controller then determines whether there are any alarms or limit-exceeding shutdown issues, and whether the startup conditions are met. Each air compressor must be started and stopped on-site, operating independently and not in a chain. As a result, the host computer can only monitor the operating status of each air compressor via a serial unidirectional communication network, but cannot operate them. After an air compressor malfunctions and stops, it is difficult for the operator to immediately determine the cause of the stoppage. They can only inspect and restart the compressor on-site, or start a backup air compressor on-site to ensure the compressed air pressure of the unit. When operators need to adjust the amount of compressed air used according to the operating status of the unit equipment, they have no choice but to go to the site and start or stop the corresponding air compressor. If there is a problem with the air compressor, they cannot be notified of the abnormal situation in a timely manner. Furthermore, each air compressor monitors its operating status only via a serial unidirectional communication network, which has a high failure rate, and a single point of failure often causes an interruption of the entire network, resulting in a loss of monitoring functionality.

[0004] Conventional air compressor control systems require operators to perform on-site operations, which not only increases the workload of the operators but also makes it difficult to rapidly stabilize the compressed air pressure in the unit. Furthermore, monitoring the air compressor's operating status is unstable, preventing timely remote alarms and posing a potential risk to the safe operation of the unit.

[0005] Therefore, designing an air compressor control system with interlock control functions such as remote start / stop and remote monitoring is a problem that needs to be solved urgently. [Overview of the Initiative]

Modes for Carrying Out the Invention

[0023] Hereinafter, exemplary embodiments of the present disclosure will be described with reference to the drawings. The description includes various details of the embodiments of the present disclosure for the purpose of assisting understanding, which should be regarded as merely exemplary. Therefore, those skilled in the art should recognize that various changes and modifications can be made to the embodiments described herein without departing from the scope and spirit of the present disclosure. Similarly, for the purpose of clear and concise description, the description of known functions and structures will be omitted in the following description.

[0024] In the following, the air compressor control system, method, apparatus, and electronic equipment in embodiments of this disclosure will be described with reference to the drawings.

[0025] Figure 1 is a schematic diagram of the structure of an air compressor control system provided by an embodiment of this disclosure.

[0026] As shown in Figure 1, the air compressor control system includes a signal distributor 11, an auxiliary controller 12, and a distributed controller 13. The signal distributor 11 is used to acquire a monitoring signal from the controlled device, perform signal branching processing on the monitoring signal, and obtain a first signal and a second signal. The signal distributor 11 is further used to transmit the first signal to the scheduled control system and the second signal to the auxiliary controller 12, where the scheduled control system is the on-site control system of the controlled device. The auxiliary controller 12 is used to receive the second signal and transmit the second signal to the distributed controller. The distributed controller 13 receives the second signal and is used to determine the state of the controlled device based on the second signal. The distributed controller 13 is further used to respond to a triggered device control command, generate a control signal based on the device control command and the device state, transmit the control signal to the controlled device via the auxiliary controller 12, and perform remote control processing on the controlled device.

[0027] Here, in this embodiment of the signal distributor 11, one signal distributor principle diagram is shown. As shown in Figure 2, the signal distributor 11 can split the sensor measurement value (the monitoring signal) received by the PLC controller into two passes without changing the PLC control method of the original air compressor, send the signal from one pass (first signal) back to the original on-site control system (planned control system), and use the signal from the other pass (second signal) to enable remote monitoring and control of the air compressor and chain start / stop between each air compressor.

[0028] The auxiliary controller 12 is a controller that can be customized and selected from the electronic control panel of a distributed control system (DCS). It is used to add or find and wire available AI card and DI card channels, thereby facilitating the reception of second signals uploaded from the signal distributor and providing signal support for remote monitoring and remote control software configurations.

[0029] The distributed controller 13 may be a DCS controller selected through customization, and the distributed controller 13 has pre-designed software embedded in it. The software includes core functions such as start / stop, monitoring, and alarm functions for each air compressor, as well as optimization functions such as interlocking and locking of the air compressors. Each air compressor forms a single remote control network, and the network performance must be superior to the original air compressor status monitoring network, while the original network must be maintained as an auxiliary network. The software employs several functional blocks or typical logic editing concepts, and by adding means such as filtering and delay, interference-tolerant and scalable designs are achieved.

[0030] It should be explained that the air compressor control system requires physical support from hardware equipment and configuration and operation of a software system. The software employs different editing methods, each resulting in different effects and requiring different additional hardware equipment. By combining the software configuration with existing hardware equipment or commonly available low-cost hardware equipment, the hardware equipment is driven, and the remote control system operates correctly. For example, the software design is created using DCS control logic, and remote control is integrated into an auxiliary DCS network. The software configuration can be done by the software and hardware equipment of the control auxiliary network itself, resulting in a simple structure and high scalability.

[0031] The air compressor control system provided in this disclosure includes a signal distributor, an auxiliary controller, and a distributed controller, wherein the signal distributor is used to acquire a monitoring signal of a controlled device, perform signal branching on the monitoring signal to obtain a first signal and a second signal, the signal distributor is further used to transmit the first signal to a scheduled control system and the second signal to the auxiliary controller, where the scheduled control system is the on-site control system of the controlled device, the auxiliary controller is used to receive the second signal and transmit the second signal to the distributed controller, the distributed controller is used to receive the second signal and determine the state of the controlled device based on the second signal, the distributed controller is further used to respond to a triggered device control command, generate a control signal based on the device control command and the device state, transmit the control signal to the controlled device by the auxiliary controller, and perform remote control processing on the controlled device. Compared with related technologies, the embodiments of this disclosure divide the monitoring signal of the controlled device into two paths, transmit the signal from one path to a local control system for local control and monitoring, and input the signal from the other path to a distributed controller for remote control and remote detection. This makes it possible to design an interlock control remote control system with remote start / stop and remote monitoring without modifying the existing field control system.

[0032] In one feasible embodiment of the present disclosure, the system further includes a sensor 14. The sensor 14 is used to perform monitoring processing on the controlled device, generate the monitoring signal, and transmit the monitoring signal to the signal distributor.

[0033] Here, the sensor 14 is a custom-provided sensor for detecting the air compressor, and is a sensor that detects seven important analog quantity signals, such as the temperature of the air compressor head 1, the temperature of the air compressor head 2, ambient temperature, the oil temperature of the air compressor, the oil pressure of the air compressor, the air filtration differential pressure of the air compressor, and the oil-hydrogen differential pressure of the air compressor.

[0034] In one feasible embodiment of the present disclosure, the system further includes a signal transmission circuit 15, The signal transmission circuit 15 is used to connect the signal distributor 11 to the planned control system, the auxiliary controller 12, and the sensor 14, respectively. The signal transmission circuit 15 is further used to connect the distributed controller 13 to the auxiliary controller 12 and to connect the auxiliary controller 12 to the controlled device. The signal transmission circuit 15 is further used to perform signal transmission processing on the monitoring signal, the first signal, the second signal, and the control signal.

[0035] Here, the material of the signal transmission circuit 15 is a material selected through customization, such as a multi-core cable. Multi-core cables are a common signal transmission method, are mature in nature, have excellent interference resistance, are easy to wire, and are easy to inspect and repair.

[0036] Regarding the wiring of the signal distributor 11 by the signal transmission circuit 15, the embodiment of this disclosure shows a wiring diagram of the signal distributor. As shown in Figure 3, the single-signal active signal distributor using 24V direct current (DC) power supply mode shares power with the PLC controller. The main measurement signals of the air compressor are seven important analog quantity signals: air compressor head temperature 1, air compressor head temperature 2, ambient temperature, air compressor oil temperature, air compressor oil pressure, air compressor air filtration differential pressure, and air compressor oil-hydrogen differential pressure. The seven signal sensor monitoring data are input as signals at the input terminal of the signal distributor, and the output terminal of the signal distributor adopts a two-pass configuration, with the signal from one pass being input to the PLC as the original local control system signal, and the signal from the other pass being input to the higher-level DCS card as a remote monitoring / control signal.

[0037] In one feasible embodiment of the present disclosure, the distributed controller 13 is further used to determine whether or not abnormal information exists in the controlled device based on the device state. The distributed controller 13 is further used to generate alarm information based on abnormal information when it determines that abnormal information exists in the controlled device, and to perform alarm processing based on the alarm information.

[0038] In one feasible embodiment of the present disclosure, the distributed controller 13 is also used to implement interlock and lock functions of the controlled device.

[0039] Here, the air compressor control system uses a signal distributor 11 to split the monitored values ​​from each measuring sensor of each air compressor into two signal paths. The signal is designed as follows depending on its intended use: Of the two signal paths from the signal distributor, one path is still transmitted to the original local PLC controller to control the air compressor for on-site start / stop, on-site monitoring, alarms, etc. The other path is uploaded to the host computer network via a signal transmission line to establish a remote control, monitoring, and alarm system for the air compressor.

[0040] Figure 4 is a flowchart of the air compressor control method provided by an embodiment of the present disclosure.

[0041] As shown in Figure 4, the method includes the following steps 401 to 404. In step 401, a monitoring signal from the controlled device is acquired, and a signal branching process is performed on the monitoring signal to obtain a first signal and a second signal.

[0042] In embodiments of this disclosure, the monitoring signal may be feedback of parameters such as the operating status of the device, temperature, pressure, flow rate, and speed. The monitoring signal is typically acquired by a sensor or other monitoring device, exists as an electrical signal, and may be an analog or digital signal.

[0043] Signal branching is the process of dividing a single monitoring signal into two or more independent signal paths. This may be implemented by physical means (e.g., the use of relays, switches, or signal distributors) or electronic means (e.g., the use of analog or digital circuits). The purpose of branching is to copy or separate the initial signal into multiple signals according to different control or monitoring purposes. Here, the first signal and the second signal are signals obtained by copying the monitoring signal.

[0044] After signal splitting, the monitoring signal is separated into at least two different signals, namely a first signal and a second signal, which may have the following characteristics or uses: The signal on one path is still sent to the original local PLC controller to control the air compressor for local start / stop, local monitoring, alarms, etc. The signal on the other path is uploaded to the host computer network via the signal transmission line to establish a remote control, monitoring, and alarm system for the air compressor.

[0045] In step 402, the first signal is transmitted to the scheduled control system to perform on-site control processing on the controlled device.

[0046] In embodiments of the present disclosure, the scheduled control system is the on-site control system of the controlled device, and the type of the scheduled control system includes, but is not limited to, a programmable logic controller (PLC), a distributed control system (DCS), a remote terminal unit (RTU), or other similar control devices. Transmission can be performed by wired means (e.g., cable, optical fiber) or wireless means (e.g., radio waves, Wi-Fi, Bluetooth, etc.).

[0047] On-site control processing refers to control operations performed directly at the site where the equipment is located.

[0048] In step 403, the state of the controlled device is determined based on the second signal, where the planned control system is the on-site control system of the controlled device.

[0049] In the embodiments of this disclosure, the device state, which is the current state of the device, is evaluated by a second signal received from the controlled device. The second signal includes important information regarding the operation of the device, such as parameters such as temperature, pressure, speed, vibration, and current consumption. By analyzing these parameters, the planned control system can determine whether the device is within its normal operating range, whether maintenance is required, or whether a malfunction has occurred.

[0050] The second signal is obtained from the controlled device and is used to determine the real-time status of the device. Once the device status is determined, the planned control system takes corresponding control actions based on this information. These actions may include starting or stopping the device, adjusting device parameters, triggering alarm systems, or executing other necessary control logic.

[0051] In step 404, in response to a triggered device control command, a control signal is generated based on the device control command and the device state, and remote control processing is performed on the controlled device in accordance with the control signal.

[0052] In embodiments of the present disclosure, responding to a triggered device control command means that the system receives a device control command transmitted from an external or internal source. The device control command may be manually entered or automatically generated, such as a command from a host computer, monitoring system, or other control system.

[0053] After receiving a device control command, the system combines current device status information to generate a single control signal. This device status information typically includes device operating parameters, fault codes, safety status, etc. The generated control signal is then used to remotely control the controlled device. Remote control means that the control system does not necessarily need to be physically close to the device, but transmits the control signal via a network, wireless communication, or other telecommunication means. Remote control processes may include starting or stopping the device, adjusting device parameters, and executing specific operational flows.

[0054] Specifically, embodiments of this disclosure can be implemented as follows, but are not limited thereto. When the device control command is a device start command and the device state indicates that all conditions satisfy the start request, the control signal becomes a start command.

[0055] If the device control command adjusts the device speed, but the device condition indicates that the device is overheating, the control signal may either trigger the cooling system before adjusting the speed, or directly delay the speed adjustment until the device has cooled to a safe temperature.

[0056] Once a control signal is generated, it is transmitted to the control system of the controlled device via a network or other means of communication, and the system performs the corresponding operation based on the control signal.

[0057] In one feasible embodiment of the present disclosure, after determining the device state of the controlled device based on the second signal, the following method may be used, but is not limited to this method: it may be determined whether or not abnormal information exists in the controlled device based on the device state, and if it is determined that abnormal information exists in the controlled device, alarm information may be generated based on the abnormal information, and alarm processing may be performed based on the alarm information.

[0058] In the embodiments of this disclosure, continuous monitoring and analysis of the device status is performed to detect whether any abnormal conditions exist. The device status typically includes real-time data provided by various sensors and monitors, such as temperature, pressure, vibration, current, and rotational speed. The air compressor control system determines whether the device status is normal based on a preset parameter range or threshold. If the detected parameter is outside the normal range, the air compressor control system determines that abnormal information exists.

[0059] The air compressor control system generates alarm information based on detected abnormal information. The alarm information typically includes the type of abnormality, time of occurrence, location, severity, and possible suggested measures. The generation of alarm information may be automated, and the air compressor control system defines the content and format of the alarm based on pre-set rules or algorithms.

[0060] Based on the above, the embodiments of this disclosure can achieve the following technical effects.

[0061] In the embodiments of this disclosure, the monitoring signal of the controlled device is split into two paths, the signal from one path is transmitted to the on-site control system for on-site control and monitoring, and the signal from the other path is input to a distributed controller for remote control and remote detection. This makes it possible to design an interlock control remote control system with remote start / stop and remote monitoring without modifying the existing on-site control system.

[0062] Corresponding to the air compressor control method described above, the present invention further proposes an air compressor control device. The apparatus embodiment of the present invention corresponds to the method embodiment described above, and details not disclosed in the apparatus embodiment can be found by referring to the method embodiment described above, and will not be described again in the present invention.

The system includes a control unit 54 that responds to a triggered device control command, generates a control signal based on the device control command and the device state, and performs remote control processing on the controlled device in accordance with the control signal.
