step S101: and acquiring the total flow of the compressed gas transmitted to a plurality of gas-using equipment by the air compressing device.
After the air compressing device generates the compressed gas, the compressed gas needs to be transmitted to each gas consuming device which needs to use the compressed gas. In an application scene, can be through a house steward and a plurality of branch connection between air compression device and a plurality of gas appliances, house steward connection air compression device, gas appliances are connected to branch pipe one end, and house steward is connected to the other end, and the compressed gas that produces from air compression device passes through the house steward earlier, then gets into gas appliances from the branch pipe process that corresponds respectively. Therefore, the total flow of the compressed gas transmitted to the plurality of gas utilization equipment by the air compression device can be obtained through the acquisition module arranged at the gas outlet of the main pipe or the air compression device. Specifically, the total flow rate of the compressed gas delivered by the air compressing device in a certain period of time may be obtained, for example, a certain period of time may include 10 minutes, 15 minutes, or 30 minutes, etc.
Further, the step of obtaining a total flow rate of the compressed gas transmitted from the air compressing device to the plurality of gas consuming apparatuses (step S101) includes: the total compressed flow, pressure, temperature and instantaneous flow of the compressed gas are obtained. And calculating the total flow rate of the compressed gas under the standard condition based on an ideal gas state equation.
In this embodiment, the total flow rate of the compressed gas transmitted from the air compressing device to the gas consuming equipment can be converted into the total flow rate under the standard condition, so as to facilitate the reasonable distribution of the total flow rate of the subsequent compressed gas. The ideal gas state equation is: (P1 × Q1)/t1 ═ P × Q)/t. Wherein P1 is the air pressure under standard conditions, equal to about 101.325 kpa; q1 is the total flow rate of compressed gas at standard conditions; t1 is the air temperature at standard conditions, approximately equal to 273.15K; p is the measured pressure, Q is the measured total flow, and t is the measured temperature.

For example, one or more of a plurality of gas consuming apparatuses with a large number of types may be selected as the representative gas consuming apparatus, or one or more of the plurality of gas consuming apparatuses with a power level in a median may be selected as the representative gas consuming apparatus.
The average flow rate may be an average flow rate representing an average flow rate of the compressed gas required by the gas consuming apparatus over a certain period of time, and the average flow rate may be an average flow rate under a standard condition so as to facilitate a reasonable distribution of the total flow rate of the subsequent compressed gas.

step S201: the ventilation time is obtained from a first preset time period representative of the gas-using equipment.
A timing module may be provided at the representative gas consumer, by which a ventilation time of the representative gas consumer within a first preset time period is detected. In an application scenario, the first predetermined time period may be 10 minutes, and a detection within 10 minutes represents a ventilation time of 120 seconds for the gas-using apparatus.
Step S202: a representative total flow rate representative of the compressed gas taken by the gas-using device over the first predetermined time period is taken.
An acquisition module can be arranged on each pipeline for connecting the representative gas-using equipment, and the representative total flow of the compressed gas acquired in the representative gas-using equipment within the first preset time period is acquired through the acquisition module. Wherein, the representative total flow rate may be a representative total flow rate under a standard condition, specifically, step S202 may include: and acquiring representative total compressed flow, pressure, temperature and instantaneous flow representing the compressed gas required by the gas consumption equipment, and calculating to obtain a representative total flow representing the gas consumption equipment under standard conditions based on an ideal gas state equation.
The ideal gas state equation is: (P1 × Q1)/t1 ═ P × Q)/t. Wherein P1 is the air pressure under standard conditions, equal to about 101.325 kpa; q1 is the total flow rate of compressed gas at standard conditions; t1 is the air temperature at standard conditions, approximately equal to 273.15K; p is the measured pressure, Q is the measured cumulative flow, and t is the measured temperature. A representative total flow rate representative of the gas-using equipment under standard conditions may be obtained based on the actually detected parameters.
Step S203: the representative total flow was divided by the aeration time to obtain the average flow.
In an application scenario, the first predetermined time period may be 10 minutes, a detection within 10 minutes may represent an aeration time of the gas consumer of about 120 seconds, and a representative total flow rate of compressed gas obtained by the gas consumer within the first predetermined time period may represent about 4.5Nm3At this point, it may represent a total flow of 4.5Nm3The average flow rate was about 0.038Nm divided by the aeration time of 120 seconds3/S。

step S301: the method includes dividing a plurality of gas using equipment into a plurality of gas using categories based on preset conditions.
The preset conditions include the function or power of the gas-using equipment. For example, the gas-using devices can be classified into three major categories, namely, pneumatic control elements, pneumatic actuators and pneumatic auxiliary elements, according to their functions. The power consumption can be classified into high power consumption equipment and low power consumption equipment.
Step S302: and selecting a gas using device from each gas using type as a representative gas using device.
The meter gas-consuming equipment can be replaced from each gas-consuming equipment according to actual conditions, and the representative gas-consuming equipment in each category can be one or more. For example, when the plurality of gas-consuming apparatuses are classified into three types, namely, a pneumatic control element, a pneumatic actuator element, and a pneumatic auxiliary element according to functions, one or more representative gas-consuming apparatuses may be selected from the three types, respectively, and may be used as representative gas-consuming apparatuses of the three types of gas-consuming apparatuses, respectively. Therefore, all the gas consuming equipment are classified, and then the gas consuming equipment is selected from each class of gas consuming equipment to replace the meter gas consuming equipment, so that the obtained average flow rate of the compressed gas required by the representative gas consuming equipment is closer to the average flow rate of the same class of gas consuming equipment, and the result of distributing the total flow rate of the compressed gas to each gas consuming equipment is more accurate.
Further, the step of obtaining the cumulative flow rate of each gas-using device based on the gas-using time and the average flow rate may include: the gas usage time of the same kind of gas-using equipment is multiplied by the average flow rate of the representative gas-using equipment to obtain the cumulative flow rate of each gas-using equipment.

Thus, the cumulative flow rates of the 5 air guns can be obtained by multiplying the air usage time of each air gun by the average flow rate of the representative air gun, respectively, to obtain a cumulative flow rate of about 5.63Nm3、4.88Nm3、4.69Nm3、4.99Nm3And 2.21Nm3。
Selecting one or more representative cylinders from the plurality of cylinders, detecting a representative cylinder ventilation time of about 58 seconds in 10 minutes, and a representative total flow rate of compressed gas taken by the representative cylinders in 10 minutes of about 10.9Nm3At this point, it may represent 10.9Nm of total flow3The average flow rate was about 0.188Nm by dividing the gas usage time by 58 seconds3and/S. Wherein, the number of the plurality of cylinders is 5, and the gas using time of the first cylinder in 10 minutes is about 57 seconds; the gas consumption time of the second cylinder in 10 minutes is about 59 seconds; the gas using time of the third cylinder in 10 minutes is about 57 seconds; fourth oneThe gas using time of the cylinder in 10 minutes is about 57 seconds; the gas usage time for the fifth cylinder in 10 minutes is about 58 seconds. Thus, the cumulative flow rates of 5 cylinders can be obtained by multiplying the gas usage time of each cylinder by the average flow rate of the representative cylinder, respectively, and are about 10.71Nm3、11.09Nm3、10.71Nm3、10.71Nm3And 10.90Nm3。
One or more representative cooling molds are selected from the plurality of cooling molds, and it is detected that the representative cooling mold vent time is about 178 seconds in 10 minutes, and that the representative total flow rate of the compressed gas taken in 10 minutes for the representative cooling molds is about 6.3Nm3At this point, it may represent a total flow of 6.3Nm3The average flow rate was about 0.035Nm by dividing by the gas usage time of 178 seconds3and/S. Wherein, the number of the cooling moulds is 5, and the air using time of the first cooling mould in 10 minutes is about 177 seconds; the second cooling mold was used for about 179 seconds in 10 minutes; the air time for the third cooling mold within 10 minutes is about 178 seconds; the air time for the fourth cooling mold within 10 minutes was about 177 seconds; the air time for the fifth cooling mold within 10 minutes was about 179 seconds. Thus, the cumulative flow rates of 5 cooling molds each having a cumulative flow rate of about 6.26Nm can be obtained by multiplying the air usage time per cooling mold by the average flow rate representing the cooling mold3、6.34Nm3、6.30Nm3、6.26Nm3And 6.34Nm3。
Wherein, the sum of the cumulative flow rates of 5 cooling dies and 5 air guns and 5 air cylinders can be obtained by adding the cumulative flow rates of 5 air guns, and the sum of the cumulative flow rates of each air appliance is about 108.1Nm3. The cumulative flow rate per gas-using equipment is divided by 108.1Nm3Obtaining the ratio of each gas utilization device, and multiplying the ratio of each gas utilization device by the total flow 115.12Nm transmitted by the air compression device3To obtain respectively 5 air guns distributing about 6.00Nm of flow3、5.20Nm3、5.00Nm3、5.32Nm3And 2.36Nm3(ii) a The flow rates distributed by the 5 cylinders are about 11.42Nm respectively3、11.82Nm3、11.42Nm3、11.42Nm3And 11.62Nm3(ii) a The flow rates allocated to the 5 cooling dies were about 6.68Nm each3、5.75Nm3、6.71Nm3、6.68Nm3And 6.75Nm3。
Therefore, in this embodiment, the gas-using equipment can be classified first, then representative gas-using equipment is selected from different classes, and only by detecting the gas metering of the representative gas-using equipment, the accumulated flow rates of a plurality of gas-using equipment are obtained, so that the accuracy of the obtained accumulated flow rates of the plurality of gas-using equipment is improved. Meanwhile, the compressed gas can be distributed based on the accumulated flow, so that the energy consumption index of the compressed gas can be decomposed to production teams, machines and individuals according to the distribution result of the compressed gas, the energy consumption management can be enhanced, and the energy-saving control measures can be taken in time to reduce the waste of the compressed gas.
