Detailed Description
The present invention will be described in further detail with reference to the accompanying drawings and examples. It is to be understood that the specific embodiments described herein are merely illustrative of the invention and are not limiting of the invention. It should be further noted that, for the convenience of description, only some of the structures related to the present invention are shown in the drawings, not all of the structures.
In practical use of the gas control, the gas inlet of the gas control box is communicated with the section of pipeline of the gas source, and the pipeline is reliable and is not easy to leak. The gas control box (including the gas pipe therein) is damaged due to the influence of factors such as materials, material processes, manufacturing quality and the like, and operating elements are damaged, so that leakage is easy to occur, and generally, the leakage is weak, so that a user cannot know the leakage problem or can check the gas leakage after a certain time, and the waste of gas use is caused. Against this background, the present embodiment provides a novel gas control box to solve the leakage problem of the gas control box.
Fig. 1 is a block diagram of a gas control box according to an embodiment of the present invention, and fig. 2 is a schematic structural diagram of the gas control box according to the embodiment of the present invention. The gas control box can be used for controlling pneumatic equipment driven by gas, such as stamping equipment and the like. The gas control box that this embodiment provided improves the control algorithm of gas tank, can leak the control to the gas tank, optimizes through the inner structure to the gas tank moreover, can improve the life of gas tank. Referring to fig. 1 and 2, the gas control box includes: a first chamber 210 and a second chamber 220 which are arranged in an isolated manner; two opposite side walls of the first chamber 210 are provided with an air inlet 211 and an air outlet 212, the air inlet 211 is communicated with an air source, the air outlet 212 is communicated with pneumatic equipment, and the air inlet 211 is provided with a flow meter 20 and an air inlet valve 30; a control module 10 is arranged in the second chamber 220, and the control module 10 is connected with the flowmeter 20; wherein the content of the first and second substances,
the flow meter 20 is used for detecting the air supply quantity of the air source to the pneumatic equipment per unit time;
the control module 10 is configured to: updating the accumulated air supply quantity of the air source to the pneumatic equipment in real time based on the air supply quantity in unit time and the working duration of the pneumatic equipment;
updating the time-average flow, the daily-average flow and the monthly-average flow of the gas in real time based on the accumulated gas supply amount;
detecting whether the gas control box leaks or not based on the flow ratio of the time-average flow to the daily-average flow and/or the flow ratio of the daily-average flow to the monthly-average flow;
if the gas control box leaks, the inlet valve 30 is closed to halt the supply of gas to the pneumatic device.
The gas control box comprises a first chamber 210 and a second chamber 220 which are arranged in an isolated mode, a gas inlet 211 and a gas outlet 212 are arranged on two side walls of the first chamber 210, the control module 10 is placed in the second chamber 220, and the control module 10 is isolated from gas. The advantage of this arrangement is that, because the gas usually contains a certain amount of moisture, and the control module 10 belongs to an electronic device, by isolating the control module 10 from the gas, the influence of the moisture on the control module 10 can be avoided or reduced, so that the control module 10 does not have the problem of malfunction or program malfunction due to the influence of the moisture in the prior art, thereby improving the operational reliability of the gas control box, also contributing to the delay of the service life of the gas control box, and reducing the maintenance and repair costs.
When the air inlet valve 30 is opened, air can enter the air control box, and when the air inlet valve 30 is closed, air is not allowed to enter the air control box, so that the air supply of the air source to the pneumatic equipment is controlled through the air inlet valve 30. The intake valve 30 is electrically connected to the control module 10, so that the on/off of the intake valve 30 can be automatically controlled by the control module 10.
The flow meter 20 is disposed at the gas inlet 211 and within the gas control box. The method is used for counting the gas consumed by the pipeline from the gas control box to the pneumatic equipment, namely counting the gas supply quantity of the gas source to the pneumatic equipment. When the gas control box leaks, the amount of gas consumed in the pipe from the gas control box to the pneumatic equipment increases, and the amount of gas supplied per unit time detected by the flow meter 20 increases. The control module 10 can timely detect whether the gas control box has leakage or not by calculating through a built-in detection strategy based on the characteristics.
The control module 10 is provided with a detection program, the control module 10 may be a PLC controller, for example, and the control module 10 realizes a detection function for the gas control box by executing the built-in detection program. Specifically, the control module 10 can calculate the accumulated air supply amount of the air supply to the pneumatic equipment based on the air supply amount per unit time and the operating time of the pneumatic equipment, and the accumulated air supply amount is updated in real time.
The control module 10 further calculates an average air supply amount per hour, which is an average time flow, an average air supply amount per 24 hours, which is an average daily flow, and an average air supply amount per 30 days, which is an average monthly flow, according to the accumulated air supply amount. Since the integrated air supply amount is updated in real time, the time-averaged flow rate, the daily-averaged flow rate, and the monthly-averaged flow rate obtained based on the integrated air supply amount are also updated in real time. It can be known that when the gas control box does not leak, the time-average flow, the day-average flow and the month-average flow should be kept relatively stable, and accordingly, the flow ratio of the time-average flow to the day-average flow and the flow ratio of the day-average flow to the month-average flow are relatively stable; and once the gas control box leaks, the time average flow, the day average flow and the month average flow all correspondingly change, the flow ratio of the time average flow to the day average flow and the flow ratio of the day average flow to the month average flow correspondingly change, and whether the variable quantity is obvious depends on the leakage degree of the gas control box.
Based on this principle, when the flow ratio of the average daily flow to the average daily flow and/or the flow ratio of the average daily flow to the average monthly flow changes to a certain extent when the control module 10 detects that the gas control box leaks, the control module 10 may determine that the gas control box leaks, and control the gas inlet valve 30 to close when the gas control box leaks, so as to stop supplying gas to the pneumatic equipment, thereby avoiding further waste of gas.
The gas control box that this embodiment provided, through improving the box structure, keep apart control module 10 with gaseous, can avoid control module 10 to expose in moist gas environment or can reduce the length of time that control module 10 exposes in moist gas environment to through the last isolation setting of physical structure and protection control module 10 can not appear malfunctioning because of receiving the environmental impact, guarantee control module 10 and gas control box reliable and stable work. The control module 10 updates the time-average flow, the day-average flow and the month-average flow of the gas supplied from the gas source to the pneumatic device in real time by acquiring the gas supply amount per unit time output by the flow meter 20, because the time-average flow, the day-average flow and the month-average flow are updated in real time, the control module 10 can detect whether the gas control box has leakage according to the built-in algorithm by calculating the flow ratio of the time-average flow to the day-average flow and the flow ratio of the day-average flow to the month-average flow in real time, and when detecting that the gas control box has leakage, the gas inlet valve 30 of the gas control box is opened to stop supplying gas to the pneumatic device, thereby avoiding further waste of gas. In this embodiment, the control module 10 can automatically and timely detect whether the gas control box has leakage by running the built-in program, and timely operate when detecting the leakage.
Optionally, on the basis of the above embodiment, reference is continued to fig. 1. The control module 10 is further configured to: calculating a first flow ratio of the average flow during the real-time process to the average daily flow and a second flow ratio of the average daily flow to the average monthly flow;
if the first flow ratio is greater than or equal to the first threshold and/or the second flow ratio is greater than or equal to the second threshold, a gas control box leak is determined.
From the above analysis, it is found that when the gas control box is not leaking, the first flow rate ratio of the time-average flow rate to the daily-average flow rate and the second flow rate ratio of the daily-average flow rate to the monthly-average flow rate are relatively stable. In the present embodiment, a first threshold is configured in advance in the control module 10 to represent a boundary where the flow ratio of the average flow rate over time and the average flow rate over day is stable, and a second threshold is configured for the control module 10 to represent a boundary where the flow ratio of the average flow rate over day and the average flow rate over month is stable, so that the control module 10 compares the first flow ratio calculated in real time with the first threshold, and compares the second flow ratio with the second threshold to detect whether the gas control box has a leak.
When the gas control box leaks, the average daily flow can be faster than the average monthly flow and change. Thus, the first flow ratio will change faster than the second flow ratio, i.e. in actual use, when the gas control box leaks, the control module 10 will first detect that the first flow ratio exceeds the first threshold.
Meanwhile, the flow average value is counted according to the gas flow within a period of time, obviously, the shorter the counting time is, the more obvious the influence of the flow change on the flow average value is, and the longer the counting time period is, the less obvious the influence of the flow change on the flow average value is. Even when the leak ratio is small, the second flow rate ratio is not caused to exceed the second threshold value. Conversely, if the second flow ratio is detected to exceed the second threshold at a certain time, indicating that a large leak is occurring at that time, the control module 10 may perform further control actions, for example, please refer to the description of the following embodiments.
In one embodiment, the control module 10 determines that there is a leak in the gas control box when the average daily flow of gas is greater than 3% or the average daily flow of gas is greater than 4% of the average monthly flow of gas, and controls the inlet valve 30 to close to stop the gas supply to avoid further waste of gas.
Optionally, on the basis of the above embodiment, reference is continued to fig. 1. The gas control box further comprises an electromagnetic valve 40 arranged in the first chamber 210, a control end of the electromagnetic valve 40 is connected with the control module 10, and a gas outlet end of the electromagnetic valve 40 is communicated with a gas outlet 212;
the control module 10 is further configured to: when the second flow ratio is detected to be greater than or equal to the second threshold value, a closing signal of the electromagnetic valve 40 is output to control the pneumatic equipment to stop running.
The gas in the gas control box enters through the gas inlet end of the electromagnetic valve 40, and then enters the gas outlet 212 of the gas control box through the gas outlet end of the electromagnetic valve 40 to flow to the pneumatic equipment, so that the control module 10 correspondingly controls the operation of the pneumatic equipment by controlling the power on or power off of the electromagnetic valve 40.
When the control module 10 detects that the second flow ratio is greater than the second threshold, it indicates that a serious leakage has occurred at this time, and it is necessary to perform immediate maintenance and repair, and the control module 10 controls the pneumatic equipment to stop running at this time, and a worker intervenes to perform maintenance and repair on the gas control box.
In one embodiment, when it occurs that the daily average flow rate of gas used by the machine is higher than 4% of the monthly average flow rate, the control module 10 outputs a closing signal of the solenoid valve 40 to stop the gas supply to the pneumatic device.

the control module 10 is further configured to: comparing the pressure detection value with a preset pressure threshold value;
and if the pressure detection value is smaller than the pressure threshold value, determining that the gas control box leaks.
It can be known that, under the intact circumstances of gas control box, the gas pressure in the gas control box can keep relatively stable, if the gas control box takes place to leak, then gas pressure will change certainly, based on this principle, this embodiment carries out the pressure measurement tactics of pre-configuration through control module 10, detects whether there is the leakage gas control box based on the pressure condition in the gas control box, carries out leak detection to the gas control box through another tactics promptly, through the multidimension degree detection, improves the timeliness to gas control box leak detection.
The pressure detection module may be, for example, a pressure sensor. The air pressure detecting module 50 in this embodiment may be specifically disposed in the first chamber 210. In some embodiments, the number of the gas pressure detection modules 50 may be multiple, and the control module 10 determines whether there is a leak in the gas control box according to a built-in strategy based on the detection results of the multiple gas pressure detection modules 50. For example, whether there is a leak in the gas control box may be detected based on a comparison between an average value of pressure detection values output from the plurality of gas pressure detection modules 50 and a pressure threshold value; or the control module 10 compares each pressure detection value with a pressure threshold value respectively, and when any pressure detection value is detected to be smaller than the pressure threshold value, it is determined that the gas control box has leakage.
In this embodiment, the pressure detection module is arranged to detect the gas pressure in the gas control box, and the control module 10 determines whether the gas control box has leakage according to the gas pressure, thus, this embodiment provides another different method for detecting the leakage of the gas control box, and the control module 10 realizes two methods for detecting the leakage by running a set of programs, thereby further improving the timeliness of the detection of the leakage of the gas control box.

if the humidity detection value is greater than or equal to the humidity threshold value, a second alarm trigger signal is output to the alarm module 60 to trigger the alarm module 60 to alarm for humidity abnormality.
Since the control module 10 needs to be electrically connected to other detecting devices, a wire connection is needed between the first chamber 210 and the second chamber 220, and thus a certain amount of gas is inevitably introduced into the second chamber 220 through the wire hole.

The humidity detection module 70 may be a dry humidity sensor.
