As shown in fig. 1, a flowchart of an embodiment of a method for maintaining pressure of an air compressor based on cloud control according to the present application is shown. The pressure maintaining method for the air compressor comprises the following steps:
s100, collecting a pressure value of a main pipeline of the air compressor in real time;
this application sets up pressure transmitter on air compressor machine main line, gathers main pipeline pressure value P through pressure transmitter to reach high in the clouds server on with main pipeline pressure value P, so that it is right air compressor machine main line pressure value carries out real time monitoring.
Step S200, comparing the pressure value of the main pipeline of the air compressor with a preset threshold range, wherein the threshold range comprises a preset minimum pressure value and a preset maximum pressure value;
and presetting a pressure value threshold range of the air compressor main pipeline in the cloud server, wherein the pressure value threshold range is respectively a minimum pressure value Pmin and a maximum pressure value Pmax. In the production process, because production facility is concentrated and is used gas, the gas consumption can increase suddenly, if the air compressor machine opens the quantity not enough, then the condition of low pressure can appear, perhaps at the gas consumption trough time section, the high-pressure gas of production is too much, then the high-pressure condition can appear to lead to the pressure in the main pipeline to exceed threshold value scope. In order to avoid the main pipeline to lead to the accident because of pressure imbalance, this application carries out real time monitoring through high in the clouds server to the pressure of air compressor machine.

According to the application, the cloud server can monitor the pipeline pressure in real time by arranging the pressure transmitter, and start and stop operation is performed on the corresponding air compressor according to the priority of the air compressor, so that the air compressor can be inflated in time when the pipeline pressure is ensured to be low; meanwhile, when the pipeline pressure is higher, the air compressor can stop inflating in time, so that the effective control of the pipeline pressure of the air compressor is realized, and the stability of the pressure of the air compressor is ensured.
Further, as shown in fig. 2, the air compressor pressure maintaining method further includes:
step S500, monitoring the air compressor running in the loading state,
the air compressor unit is communicated with the cloud server through the Internet of things gateway when running, when the air compressor runs and loads, running state numerical values are returned to the cloud server in real time, and the cloud server forms an air compressor starting and stopping sequence according to the running state numerical values.

And after receiving the state numerical value of the air compressor, the cloud server removes the stopped air compressor out of the air compressor start-stop sequence.

Further, the step of selecting the air compressor with the highest starting priority from the air compressors in the unloading and shutdown states to start and load until the total duct pressure value is greater than the preset minimum pressure value specifically includes:
step A: when the pressure value of the main pipeline is smaller than the preset minimum pressure value and lasts for the preset abnormal time, detecting the air compressor in an unloading shutdown state;
the method comprises the steps that abnormal time T is preset in the cloud server, the pressure transmitter is connected with the internet of things gateway through an RS 485 serial port, the pressure value of a main pipeline is returned to the cloud server through the internet of things gateway in real time, and when the cloud server monitors that P is less than Pmin and T continues, the cloud server detects all air compressors in a start-stop sequence.
And B: identifying the starting priority corresponding to the air compressor in the unloading and stopping state, and selecting the air compressor with the highest starting priority for starting and loading;
the cloud server identifies the starting priority corresponding to the air compressor in the unloading shutdown state, communicates with the Internet of things gateway, and controls the air compressor controller to start and load the air compressor with the highest priority through the RS 485 serial port.
And C: after the set test time, re-detecting and judging whether the pressure value of the main pipeline is smaller than the preset minimum pressure value or not;
and presetting test time t in the cloud server, and when the test time t is reached, re-detecting and judging whether the total pipeline pressure value P is less than the preset minimum pressure value Pmin.

In addition, because the air compressor machine has the hysteresis quality after opening, consequently often after the adjustment, need postpone a period and carry out the pressure measurement again, just can obtain accurate pressure value. Further, the step of selecting the air compressor with the highest shutdown priority from the air compressors in the operating and loading state to perform unloading shutdown until the pressure value of the main pipeline is less than the preset maximum pressure value specifically includes:
step a: when the pressure value of the main pipeline is larger than the preset maximum pressure value and lasts for the preset abnormal time, detecting the air compressor in the running loading state;
the method comprises the steps that abnormal time T is preset in the cloud server, the pressure transmitter is connected with the internet of things gateway through an RS 485 serial port, the pressure value of a total pipeline is returned to the cloud server through the internet of things gateway in real time, and when the cloud server monitors that P is larger than Pmax and continues for T, the cloud server detects all air compressors in a start-stop sequence.
Step b: identifying the shutdown priority corresponding to the air compressor in the running loading state, and selecting the air compressor with the highest shutdown priority for unloading shutdown;
the cloud server identifies the starting priority corresponding to the air compressor in the unloading shutdown state, communicates with the Internet of things gateway, and controls the air compressor controller to unload and shutdown the air compressor with the highest shutdown priority through the RS 485 serial port by the Internet of things gateway.
Step c: after the set test time, re-detecting and judging whether the pressure value of the main pipeline is greater than the preset maximum pressure value;
and presetting test time t in the cloud server, and when the test time t is reached, re-detecting and judging whether the total pipeline pressure value P is greater than the preset minimum pressure value Pmax.
Step d: and repeating the steps a to b until the pressure value of the total pipeline is less than the preset maximum pressure value and the test time is continued, wherein the test time is less than the abnormal time.
When P is larger than Pmax, the steps are repeated until P is smaller than Pmax.
Further, before the step of collecting the pressure value of the main pipeline of the air compressor in real time, the method further comprises the following steps:
and acquiring the volume flow and the specific power of each air compressor, and setting the corresponding starting priority and stopping priority of each air compressor based on the volume flow and the specific power.
The volume flow and the specific power can be known according to the air compressor nameplate, wherein the specific power is the ratio of the actual air quantity and the theoretical air quantity volume of the compressor. The volume flow is usually called displacement, and is the volume of gas discharged by the air compressor in unit time under the required exhaust pressure, and is converted into the quantity of gas intake state; the unit of volume flow is: m3/min (cubic/min) or l/min (liter/min), 1m3 (cubic) ═ 1000l (liter); the commonly used flow units are: m3/min (cubic/min); the volume flow is commonly referred to as displacement or nameplate flow.

The steps are not performed in the exact order shown and may be performed in other orders unless explicitly stated herein. Moreover, at least a portion of the steps in the flow chart of the figure may include multiple sub-steps or multiple stages, which are not necessarily performed at the same time, but may be performed at different times, which are not necessarily performed in sequence, but may be performed alternately or alternately with other steps or at least a portion of the sub-steps or stages of other steps.
