Referring to fig. 1, fig. 1 is a schematic structural diagram of a calibration apparatus 10 provided in an embodiment of the present application, where the calibration apparatus 10 is configured to provide a calibration environment for an alarm 20 having an automatic calibration function, the calibration apparatus 10 includes a sample injection device 200, a standard gas box 300, and an analysis control device 400, the sample injection device 200 is connected to the standard gas box 300 through a pipeline, the sample injection device 200 is further electrically connected to the analysis control device 400, and the analysis control device 400 is electrically connected to the standard gas box 300; the sample injection device 200 is used for connecting a standard gas bottle through a pipeline and injecting the standard gas in the standard gas bottle 100 into the standard gas box 300; the gas marking box 300 is used for placing the alarm 20; the analysis control device 400 is configured to collect and analyze the concentration of the calibration gas in the calibration gas box 300 to obtain an analysis result; the analysis control device 400 is further configured to control the sample injection device 200 to inject the calibration gas in the calibration gas bottle 100 into the calibration gas box 300 according to the analysis result, so that the current environment in the calibration gas box 300 meets the requirement of a preset calibration environment.
The preset calibration environment may be the calibration parameters of the alarm 20 that are calibrated by the operator as needed and input into the analysis control apparatus 400 through the input device. It is to be understood that the calibration apparatus 10 provided in the embodiment of the present application further includes a calibration gas cylinder 100.
When an operator performs a calibration process operation in the production of the alarm 20, the alarm 20 in the automatic calibration mode is placed in the standard gas box 300 of the calibration device 10, the alarm 20 inside the standard gas box 300 is sealed or isolated from the external environment, so as to prevent the environment in the standard gas box 300 from being affected by the external environment, then the sample injection device 200 injects the calibration gas in the standard gas bottle 100 into the standard gas box 300, and meanwhile, the analysis control device 400 collects the concentration of the calibration gas in the standard gas box 300 and analyzes the concentration to obtain an analysis result, and controls the sample injection device 200 to inject the calibration gas in the standard gas bottle 100 into the standard gas box 300 according to the analysis result until the concentration of the calibration gas in the standard gas box 300 meets a preset calibration environment for automatic calibration by the alarm 20, so that the alarm 20 can perform automatic calibration.

Referring to fig. 2, fig. 2 is a schematic structural diagram of an analysis control apparatus 400 according to an embodiment of the present disclosure, in which the analysis control apparatus 400 includes a calibration gas concentration acquisition module 410 and a processing module 420, the calibration gas concentration acquisition module 410 is disposed in the calibration gas box 300, and the calibration gas concentration acquisition module 410 is electrically connected to the processing module 420; the calibration gas concentration acquisition module 410 is configured to acquire the calibration gas concentration in the calibration gas box 300 and send the calibration gas concentration to the processing module 420; the processing module 420 is configured to analyze whether the calibrated gas concentration meets a requirement of a gas concentration in a preset calibration environment, and obtain an analysis result; the processing module 420 is further configured to control the sample injection device 200 to inject the calibration gas in the calibration gas bottle 100 into the calibration gas box 300 according to the analysis result, so that the current environment in the calibration gas box 300 meets the requirement of a preset calibration environment.
The calibration gas concentration acquisition module 410 may be a gas sensor, generates different voltage signals according to the change of the calibration gas concentration, and after the calibration gas concentration acquisition module 410 acquires the calibration gas concentration in the calibration gas tank 300, sends the generated voltage signals to the processing module 420, so that the processing module 420 processes the voltage signals, analyzes whether the calibration gas concentration meets the requirement of the gas concentration of the preset calibration environment, and obtains an analysis result, and finally controls the sample injection device 200 to inject the calibration gas in the calibration gas bottle 100 into the calibration gas tank 300 according to the analysis result, so that the current environment in the calibration gas tank 300 meets the requirement of the preset calibration environment.
In the implementation process, the calibration gas concentration acquisition module 410 in the analysis control device 400 acquires the gas concentration in the calibration gas tank 300, then the processing module 420 judges the acquired calibration gas concentration, and controls the sample injection device 200 to inject the calibration gas in the calibration gas bottle 100 into the calibration gas tank 300 until the calibration gas concentration meets the requirement of the gas concentration in the preset calibration environment, so that the plurality of alarms 20 in the calibration gas tank 300 can be automatically calibrated at the same time, and the production efficiency is further improved.
The calibration gas concentration acquisition module 410 is further configured to acquire the calibration gas concentration in the calibration gas box 300 every preset time period, and send a plurality of calibration gas concentrations to the processing module 420. For example, the calibration gas concentration acquisition module 410 may acquire the concentration of the calibration gas in the calibration gas box 300 once every 100ms, and send the acquired concentration of the calibration gas to the processing module 420, and the problem of inaccurate acquired data can be effectively avoided by acquiring data for multiple times.
Illustratively, the processing module 420 is configured to analyze whether the calibration gas concentration meets the requirement of the gas concentration of the preset calibration environment, and obtain an analysis result, including the following processes: the processing module 420 is first configured to obtain a plurality of calibration gas concentrations; the processing module 420 is further configured to calculate a parameter value for characterizing the stability of the current environment in the calibration gas box 300 according to the plurality of calibration gas concentrations; the processing module 420 is further configured to determine whether the concentration of the calibration gas meets the requirement; the processing module 420 is configured to obtain an analysis result of continuing to inject the calibration gas into the sample injection device 200 when the concentration of the calibration gas does not meet the requirement, so that the processing module 420 controls the sample injection device 200 to continue to inject the calibration gas into the calibration gas box 300 according to the analysis result until the environment in the calibration gas box 300 meets the requirement of a preset calibration environment; the processing module 420 is configured to obtain an analysis result of stopping injecting the calibration gas into the sample injection device 200 when the concentration of the calibration gas meets a requirement, so that the processing module 420 controls the sample injection device 200 to stop injecting the calibration gas into the calibration gas tank 300.
The processing module 420 is configured to calculate a parameter value for characterizing the stability of the current environment in the calibration gas box 300 according to a plurality of calibration gas concentrations, and may include the following calculation methods:
first, the processing module 420 is configured to calculate an average value of a plurality of calibration gas concentrations, and use the average value as the parameter value. For example, if the processing module 420 obtains 5 calibration gas concentration values of 1, 1.5, 1.8, 0.6 and 0.9, respectively, then it can calculate that the average value of the 5 calibration gas concentration values is 1.16, and therefore 1.16 is a parameter value representing the stability of the current environment in the gas box 300.
Secondly, the processing module 420 is configured to calculate a variance value according to a plurality of calibration gas concentrations, and use the variance value as the parameter value. For example, if the processing module 420 obtains 5 calibration gas concentration values of 1, 1.5, 1.8, 0.6 and 0.9, respectively, the variance value of the 5 calibration gas concentration values can be calculated to be 0.932, and thus 0.932 is a parameter value representing the stability of the current environment in the calibration gas box 300.
Third, the processing module 420 is configured to calculate an average value and a variance value of a plurality of calibration gas concentrations, and divide the variance value by the average value to obtain the parameter value. For example, if the processing module 420 obtains 5 calibration gas concentration values of 1, 1.5, 1.8, 0.6 and 0.9, respectively, then it can calculate that the average value of the 5 calibration gas concentration values is 1.16 and the variance value is 0.932, so that 0.803 (three decimal places are reserved) is a parameter value representing the stability of the current environment in the calibration gas box 300.
In the implementation process, the processing module 420 calculates a parameter value according to a plurality of calibration gas concentrations, and the parameter value can represent the stability of the current environment in the calibration gas box 300, so as to ensure that the alarm 20 can be automatically calibrated in a stable environment, and ensure the calibration accuracy of the alarm 20.
Optionally, the processing module 420 is configured to, after obtaining a plurality of calibration gas concentrations, include: the processing module 420 is further configured to determine whether the number of the calibration gas concentrations is greater than a preset number; the processing module 420 is further configured to continue to obtain the plurality of calibration gas concentrations when the number of the plurality of calibration gas concentrations is not greater than a preset number.
Since the accuracy of the parameter value can be ensured when the number of the calibration gas concentrations is large, it can be set that the number of the calibration gas concentrations of a certain number is calculated, for example, the preset number is set to six, when the number of the calibration gas concentrations is only 5, the calibration gas concentrations are continuously obtained until the number of the calibration gas concentrations is judged to be larger than 6, as an implementation mode, when the number of the calibration gas concentrations obtained within a certain time is only 5, the calibration gas concentrations can be obtained again within a certain time, and if the number of the calibration gas concentrations obtained again is larger than 6, the parameter value is calculated.
In the implementation process, because the number of the plurality of calibration gas concentrations is small and inaccurate parameter values may be obtained, it may be determined whether the number of the plurality of calibration gas concentrations is greater than a preset number, and when the number of the plurality of calibration gas concentrations is greater than the preset number, the parameter values are calculated, so that the stability of the current environment in the calibration gas box 300 can be accurately represented by the parameter values, thereby ensuring the calibration accuracy of the alarm 20.
Optionally, the analysis control device 400 is further configured to obtain calibration states of the plurality of alarms 20 with an automatic calibration function, where the calibration states are states in which calibration is completed or states in which calibration is not completed.
The analysis control device 400 may be connected to the alarm 20, and when the alarm 20 is in a state where calibration is completed, the analysis control device 400 may obtain a signal, which may indicate the alarm 20 to complete calibration, for example, after the alarm a completes calibration, the analysis control device 400 may obtain a completed signal sent by the alarm a, until the analysis control device 400 obtains the completed signals sent by all the alarms 20, the analysis control device 400 may prompt a worker to take out the alarm 20 in the gas marking box 300, or the analysis control device 400 may control the gas marking box 300 to withdraw the alarm 20 to a set position.
The alarm 20 can be further set to recognize the identification device that the alarm 20 finishes calibrating the indicator light, the alarm 20 finishes calibrating, the corresponding indicator light is in an off state, after the alarm 20 finishes calibrating, the corresponding indicator light becomes a bright state, the identification device recognizes whether the alarm finishes calibrating the identification result through the state of the indicator light, and sends the identification result to the analysis control device 400, so that the calibration state of the alarm 20 of the analysis control device 400 can be understood, the alarm 20 finishes calibrating, the corresponding indicator light can be in a bright state of one color, after the alarm 20 finishes calibrating, the corresponding indicator light becomes a bright state of another color, and at this time, the identification device can acquire whether the alarm 20 finishes calibrating through the color of the indicator light.
In the implementation process, after the analysis control device 400 acquires the states of all the alarms 20 that are calibrated, a calibration completion prompt can be sent, so that the staff can conveniently place a next batch of multiple alarms 20 to be calibrated into the calibration gas box 300, thereby improving the calibration efficiency and further improving the production efficiency.
In summary, the sample injection device 200 may inject the calibration gas in the calibration gas bottle 100 into the calibration gas tank 300, the analysis control device 400 may collect the concentration of the calibration gas in the calibration gas tank 300, and if the concentration of the calibration gas does not meet the requirement of the preset calibration environment, the analysis control device 400 controls the sample injection device 200 to continue to inject the calibration gas into the calibration gas tank 300 until the concentration of the calibration gas in the calibration gas tank 300 meets the requirement of the preset calibration environment, so that the plurality of alarms 20 in the calibration gas tank 300 may be automatically calibrated at the same time, thereby improving the calibration efficiency and further improving the production efficiency.
