[0004] In combination with the above technical solutions, it is found that there are microchannel reactor technical solutions that place too much emphasis on the analysis of the control effect of the microchannel reactor, resulting in the neglect of the operating risks of the microchannel reactor during use, thereby reducing the control effect of the microchannel reactor and ultimately affecting the use of the microchannel.

The specific analysis process is: the verification result is specifically the first verification result or the second verification result; the first verification result is that the actual duration of the microchannel medium passing through the first monitoring subchannel is equal to the estimated duration of the microchannel medium passing through the first monitoring subchannel; the second verification result is that the actual duration of the microchannel medium passing through the first monitoring subchannel is not equal to the estimated duration of the microchannel medium passing through the first monitoring subchannel; when the verification result is displayed as the first verification result, the initial risk control plan that matches the estimated duration is directly extracted from the microchannel medium database, and recorded as the risk control plan for the microchannel medium passing through the second monitoring subchannel; when the verification result is displayed as the second verification result, the initial risk control plan that matches the actual duration is extracted from the microchannel medium database, and recorded as the risk control plan for the microchannel medium passing through the second monitoring subchannel.

[0011] As a further solution, the real-time risk assessment index of the microchannel medium passing through the first monitoring subchannel is analyzed, and the stability assessment index of the microchannel medium passing through the first monitoring subchannel is matched. The specific analysis process is: the medium flow rate of the microchannel medium at each first passing time point is arranged in order from large to small, and the medium flow rate ranked first is recorded as the maximum medium flow rate of the microchannel medium in the first passing cycle; according to the medium initial flow rate of the microchannel medium at the inlet time point, the medium reference flow rate corresponding to each predefined medium initial flow rate interval is matched to obtain the medium reference flow rate of the microchannel medium in the first passing cycle; according to the initial stability assessment index of the microchannel medium, the pressure tolerance adaptation value corresponding to each predefined initial stability assessment index interval is matched to obtain the pressure tolerance adaptation value; according to the current generated by the microchannel medium at each first passing time point The value is used to construct a current change curve of the microchannel medium in the first passing cycle, and a number of first passing time points corresponding to current values ​​greater than the predefined current reference value are extracted from the curve, which are recorded as the number of abnormal currents of the microchannel medium in the first monitoring subchannel; the pressure adaptation value is extracted from the microchannel medium database; according to the maximum flow velocity of the microchannel medium in the first passing cycle, the medium flow rate of the microchannel medium in the first passing cycle, the maximum pressure value of the first monitoring subchannel in the first passing cycle, and the number of abnormal currents of the microchannel medium in the first monitoring subchannel, a comprehensive analysis is performed to obtain the real-time risk assessment index of the microchannel medium passing through the first monitoring subchannel; the real-time risk assessment index of the microchannel medium passing through the first monitoring subchannel is matched with the stability assessment index corresponding to each predefined real-time risk assessment index interval, so as to obtain the stability assessment index of the microchannel medium passing through the first monitoring subchannel.

If the microchannel medium stability assessment index difference belongs to the medium stability assessment difference allowable range, the risk control plan does not need to be adjusted. If the microchannel medium stability assessment index difference does not belong to the medium stability assessment difference allowable range, the risk control plan needs to be adjusted.

[0022] The technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present invention.

[0023] See also Figure 1 As shown, an embodiment of the present invention provides a technical solution: a real-time risk management and control system for microchannel media based on multivariable measurement, including an initial state determination module, a risk management and control plan matching module, a first monitoring sub-channel analysis module, a second monitoring sub-channel determination module and a risk management and control plan regulation module.

[0024] An embodiment of the present invention provides a technical solution: a real-time risk management and control system for microchannel media based on multivariable measurement, which also includes: a microchannel media database for storing medium reference flow rate, medium reference temperature, medium reference concentration, medium reference pH value, pressure adaptation value, generated current reference value and preset values ​​of various factors, etc.

[0025] The initial state determination module is connected to the risk control plan matching module and the first monitoring sub-channel analysis module, the risk control plan matching module and the first monitoring sub-channel analysis module are both connected to the second monitoring sub-channel determination module, the second monitoring sub-channel determination module is connected to the risk control plan regulation module, and the initial state determination module, the first monitoring sub-channel analysis module and the second monitoring sub-channel determination module are all connected to the microchannel medium database.

[0026] The initial state determination module is used to obtain the real-time initial state data of the medium at the microchannel inlet, determine the initial stability evaluation index of the microchannel medium, and thereby obtain the estimated time length of the microchannel medium passing through the first monitoring subchannel.

[0027] It should be explained that the microchannel, also known as a microchannel reactor, usually has an equivalent channel diameter in the range of 10μm to 1000μm. There are dozens of tiny flow channels in the flat tube of this reactor, which are connected to circular manifolds at both ends of the flat tube. Partitions are arranged in the manifold to divide the reactor flow channel into several processes. Since the external dimensions may be large, for example, reaching 1.2m×4m×25.4mm, and the hydraulic diameter of the microchannel is below 0.61mm, it is also called a large-scale microchannel reactor.

[0028] Microchannel media usually refers to the substances filled or flowing in the microchannel. In microchannel reactors and microchannel heat exchangers, liquids such as water and refrigerants are used as heat transfer media and flow in microchannels to transfer heat. In addition, in microchannel reactors, liquids can also be used as reactants or solvents.

[0029] Specifically, the initial stability evaluation index of the microchannel medium is determined by the following specific determination process:

[0030] The real-time initial state data of the medium at the microchannel inlet specifically include the initial flow rate of the medium, the initial temperature of the medium, the initial concentration of the medium and the initial pH value of the medium at the inlet time point of the microchannel medium.

[0031] The above-mentioned inlet time point refers to an instantaneous time point when the microchannel medium passes through the microchannel inlet, and the above-mentioned medium initial flow rate, medium initial temperature, medium initial concentration and medium initial pH value are all instantaneous flow rate, instantaneous temperature, instantaneous concentration and instantaneous pH value.

[0032] The initial flow velocity of the above-mentioned medium can be monitored by an instantaneous velocity sensor, the initial temperature of the medium can be monitored by a temperature sensor, the initial concentration of the medium can be monitored by an optical fiber sensing device, and the initial pH value of the medium can be monitored by a pH detector.

[0033] The medium reference flow rate, medium reference temperature, medium reference concentration and medium reference pH value are extracted from the microchannel medium database.

[0034] According to the initial flow rate of the microchannel medium at the inlet time point, the initial temperature of the microchannel medium at the inlet time point, the initial concentration of the microchannel medium at the inlet time point, and the initial pH value of the microchannel medium at the inlet time point, the initial stability evaluation index of the microchannel medium is obtained by comprehensive analysis. The specific method is as follows:

[0035] ;

[0036] In the formula, It is an initial stability evaluation index of the microchannel medium. In this embodiment, it is used to measure the stability and reliability of the microchannel medium when it initially enters the microchannel. The higher the initial stability evaluation index of the microchannel medium, the higher the stability and reliability of the medium when it initially enters the microchannel, and the lower the possibility of risk in the subsequent circulation of the microchannel medium.

[0037] It is the initial flow velocity of the microchannel medium at the inlet time point, which refers to the self-flow velocity of the medium at the inlet of the microchannel when it begins to flow into the microchannel.

[0038] The medium reference flow rate refers to the pre-set adaptation value of the medium flow rate.

[0039] It is the initial temperature of the microchannel medium at the inlet time point, which refers to the temperature of the medium at the inlet of the microchannel when the medium begins to flow into the microchannel.

[0040] The medium reference temperature refers to the adaptation value of the preset medium initial temperature.

[0041] It is the initial concentration of the medium in the microchannel at the inlet time point, which refers to the concentration of the medium itself at the inlet of the microchannel when the medium begins to flow into the microchannel.

[0042] The medium reference concentration refers to the adaptation value of the preset medium initial concentration.

[0043] It is the initial pH value of the microchannel medium at the inlet time point, which refers to the pH value of the medium itself at the inlet of the microchannel when the medium begins to flow into the microchannel.

[0044] It is the initial reference pH value of the medium, which refers to the preset adaptation value of the initial pH value of the medium, and e is a natural constant.

[0045] In this embodiment, the initial temperature of the microchannel medium will affect the flow properties of the medium. For example, when the initial temperature of the microchannel medium is high and much higher than the reference temperature, the viscosity and density of the medium will increase, thereby reducing the initial flow rate of the medium and causing it to deviate from the reference flow rate. Too high or too low a flow rate may increase the fluctuation of the medium stability and reduce the initial stability index of the microchannel medium. At the same time, when the initial temperature of the microchannel medium is high and much higher than the reference temperature, the rate of certain chemical reactions in the medium may be accelerated, thereby changing the concentration distribution of the medium. When the temperature is high or low, the concentration of the medium may deviate from the reference value. The initial temperature directly affects the temperature distribution in the microchannel. Excessive temperature fluctuations may cause changes in the reaction rate and selectivity, thereby affecting the stability of the system. In addition, the initial pH value directly affects the pH stability of the medium. Excessive fluctuations in the pH value may cause changes in the chemical reaction rate and direction of the medium, thereby affecting the stability of the system.

[0046] Furthermore, the matching obtains the estimated time length of the microchannel medium passing through the first monitoring subchannel, and the specific matching process is:

[0047] The initial stability evaluation index of the microchannel medium is matched with the estimated time length of passing through the first monitoring subchannel corresponding to each initial stability evaluation index interval. The specific matching process is: obtaining a mapping set of the initial stability evaluation index of the microchannel medium and the estimated time length of passing through the first monitoring subchannel from a microchannel medium database, determining a specific interval of the initial stability evaluation index of the microchannel medium, and obtaining the estimated time length of passing through the first monitoring subchannel corresponding to the interval, thereby matching to obtain the estimated time length of the microchannel medium passing through the first monitoring subchannel.

[0048] It should be explained that when the initial flow rate of the microchannel medium at the inlet time point, the initial temperature of the microchannel medium at the inlet time point, the initial concentration of the microchannel medium at the inlet time point, and the initial pH value of the microchannel medium at the inlet time point are relatively close to or equal to the corresponding reference values, the initial stability evaluation index of the microchannel medium is at its maximum value, and the initial stability of the microchannel medium is in an optimal state. At this time, the estimated time for the microchannel medium to pass through the first monitoring subchannel should be at its minimum value.

[0049] The risk control plan matching module is used to obtain the actual duration of the microchannel medium passing through the first monitoring subchannel, verify it with the estimated duration of the microchannel medium passing through the first monitoring subchannel, and obtain and match the risk control plan of the microchannel medium passing through the second monitoring subchannel based on the verification result.

[0050] The actual duration mentioned above can be monitored by a timer.

[0051] Specifically, the risk control plan for the microchannel medium passing through the second monitoring subchannel is obtained and matched according to the verification result. The specific analysis process is as follows:

[0052] The verification result is specifically the first verification result or the second verification result.

[0053] The first verification result is that the actual time length of the microchannel medium passing through the first monitoring subchannel is equal to the estimated time length of the microchannel medium passing through the first monitoring subchannel.

[0054] The second verification result is that the actual time length of the microchannel medium passing through the first monitoring subchannel is not equal to the estimated time length of the microchannel medium passing through the first monitoring subchannel.

[0055] When the verification result shows the first verification result, the initial risk control plan that matches the estimated duration is directly extracted from the microchannel medium database. The specific matching process is: obtain the mapping set of the estimated duration and the initial risk control plan from the microchannel medium database, match the estimated duration with the initial risk control plan corresponding to each predefined estimated duration interval, first determine the interval to which the estimated duration belongs, and assign the initial risk control plan corresponding to the interval to the estimated duration, so as to obtain the initial risk control plan that matches the estimated duration, and record it as the risk control plan for the microchannel medium passing through the second monitoring subchannel.

[0056] The above-mentioned initial risk control plan for matching the estimated duration may specifically monitor the medium flow rate of the microchannel medium through the second monitoring subchannel and control the circulation duration of the microchannel medium through the second monitoring subchannel.

[0057] When the verification result shows the second verification result, the initial risk control plan that matches the actual duration is extracted from the microchannel medium database. The specific matching process is: obtain the mapping set of the actual duration and the initial risk control plan from the microchannel medium database, match the actual duration with the initial risk control plan corresponding to each predefined actual duration interval, first determine the interval to which the actual duration belongs, and assign the initial risk control plan corresponding to the interval to the actual duration, so as to obtain the initial risk control plan that matches the actual duration, and record it as the risk control plan for the microchannel medium passing through the second monitoring subchannel.

[0058] The above-mentioned initial risk control plan matching the actual duration can specifically monitor the medium flow rate, medium concentration and current generated by the microchannel medium through the second monitoring subchannel, and control the pressure in the second monitoring subchannel when the microchannel medium passes through the second monitoring subchannel and the circulation time of the microchannel medium through the second monitoring subchannel.

[0059] It should be explained that, in the embodiment of the present invention, by determining the initial stability evaluation index of the microchannel medium, it is ensured that the microchannel medium is in a stable state when entering the first monitoring subchannel, and thereby the actual duration of the microchannel medium passing through the first monitoring subchannel is used, and the verification result of the estimated duration of the microchannel medium passing through the first monitoring subchannel is used to predict the stable state of the microchannel medium when passing through the second monitoring subchannel, and by matching the risk control plan of the microchannel medium passing through the second monitoring subchannel, it is ensured that the microchannel medium is also in a stable state when passing through the second monitoring subchannel, and thereby the subsequent flow process of the microchannel medium is monitored to reduce the risk of the medium in the flow process of the microchannel.

[0060] In this embodiment, the initial risk control plan matched with the estimated duration or the actual duration is specifically preset in the microchannel medium database based on the historical risk control data of the microchannel medium, and has a one-to-one preset relationship with the estimated duration or the actual duration.

[0061] The first monitoring subchannel analysis module is used to obtain actual passing data of the microchannel medium through the first monitoring subchannel, analyze the real-time risk assessment index of the microchannel medium through the first monitoring subchannel, and match the stability assessment index of the microchannel medium through the first monitoring subchannel.

[0062] Furthermore, the actual passing data of the microchannel medium through the first monitoring subchannel specifically includes the medium flow velocity of the microchannel medium at each first passing time point, the medium flow rate of the microchannel medium in the first passing cycle, the maximum pressure value borne by the first monitoring subchannel in the first passing cycle, and the current value generated by the microchannel medium at each first passing time point.

[0063] The above-mentioned first passing time point specifically refers to a number of first passing time points obtained by evenly dividing the first passing period into time points, and the corresponding division rule may be 30 seconds, wherein the first passing period refers to a period of time during which the microchannel medium passes through the first monitoring subchannel, and the first passing period is determined as the time period from the beginning of the microchannel medium passing through the first monitoring subchannel to the end of the microchannel medium leaving the first monitoring subchannel.

[0064] The above-mentioned medium flow velocity can be monitored by an instantaneous velocity sensor, the medium flow rate can be monitored by a flow sensor, the pressure can be monitored by a pressure sensor, and the current value can be monitored by a current sensor.

[0065] Specifically, the real-time risk assessment index of the microchannel medium passing through the first monitoring subchannel is analyzed, and the stability assessment index of the microchannel medium passing through the first monitoring subchannel is matched, and the specific analysis process is:

[0066] The medium flow rates of the microchannel medium at each first passing time point are arranged in order from large to small, and the medium flow rate ranked first is recorded as the maximum medium flow rate of the microchannel medium in the first passing cycle.

[0067] According to the initial flow velocity of the medium at the inlet time point of the microchannel medium, the medium reference flow rate corresponding to each medium initial flow velocity interval predefined in the microchannel medium database is matched. The specific matching process is: a mapping set of the medium initial flow velocity and the medium reference flow rate is obtained from the microchannel medium database, and the specific interval of the medium initial flow velocity of the microchannel medium at the inlet time point is first determined, and the medium reference flow velocity corresponding to the interval is obtained, so as to match and obtain the medium reference flow rate of the microchannel medium in the first passing cycle.

[0068] According to the initial stability evaluation index of the microchannel medium, matching is performed with the pressure-bearing adaptation value corresponding to each predefined initial stability evaluation index interval. The specific matching process is: obtaining a mapping set between the initial stability evaluation index of the microchannel medium and the pressure-bearing adaptation value from the microchannel medium database, determining the specific interval of the initial stability evaluation index of the microchannel medium, and thereby obtaining the pressure-bearing adaptation value of the microchannel medium in the first passing cycle.

[0069] According to the current value generated by the microchannel medium at each first passing time point, a current change curve of the microchannel medium in the first passing cycle is constructed, and a number of first passing time points corresponding to current values ​​greater than a predefined current reference value are extracted and recorded as the number of abnormal currents of the microchannel medium in the first monitoring subchannel.

[0070] According to the current value generated by the microchannel medium at each first passing time point, a current variation curve of the microchannel medium in the first passing cycle is constructed, such as Figure 2 As shown, the horizontal axis of the current change line is the first passing time point, the unit is second, and the vertical axis is the current value, the unit is ampere.

[0071] According to the current variation broken line, a current reference value straight line 1 is located therefrom, and a number of first passing time points corresponding to current values ​​greater than the current reference value are counted and recorded as the number of abnormal currents of the microchannel medium in the first monitoring subchannel.

[0072] The pressure adaptation value is extracted from the microchannel medium database.

[0073] According to the maximum flow velocity of the microchannel medium in the first passing cycle, the medium flow rate of the microchannel medium in the first passing cycle, the maximum pressure value of the first monitoring subchannel in the first passing cycle, and the number of abnormal currents of the microchannel medium in the first monitoring subchannel, a real-time risk assessment index of the microchannel medium passing through the first monitoring subchannel is obtained by comprehensive analysis. The specific method is as follows:

[0074] ;

[0075] In the formula, It is a real-time risk assessment index of the microchannel medium passing through the first monitoring subchannel. In this embodiment, it is used to measure the possible risk level of the medium when the microchannel medium passes through the first monitoring subchannel. When the real-time risk assessment index of the microchannel medium passing through the first monitoring subchannel is higher, it means that the stability of the medium when flowing through the first monitoring subchannel is worse and the risk is higher, and the possibility of risk of the microchannel medium in the subsequent circulation process of the second monitoring subchannel is higher.

[0076] It is the maximum flow rate of the microchannel medium in the first passing cycle. Max means the maximum, which refers to the self flow rate of the microchannel medium when the medium flows into the first monitoring subchannel in the first passing cycle.

[0077] is the reference flow rate of the medium.

[0078] It is the medium flow rate of the microchannel medium in the first passing cycle, which refers to the medium volume of the microchannel medium flowing through the first monitoring subchannel in the first passing cycle, describing the total amount of medium flow. The unit of flow rate is cubic micrometer per second.

[0079] The medium reference flow rate refers to the pre-set adaptation value of the medium flow rate.

[0080] It is the maximum pressure value that the first monitoring subchannel withstands in the first passing cycle, which means that when the microchannel medium flows through the first monitoring subchannel, the first monitoring subchannel needs to withstand the maximum value of the pressure generated by the medium flow.

[0081] The pressure adaptation value refers to the reference value of the pressure that the microchannel can withstand that is preset.

[0082] The number of abnormal currents of the microchannel medium in the first monitoring subchannel refers to the number of abnormal current signals generated by the microchannel medium when passing through the first monitoring subchannel in the first monitoring subchannel.

[0083] In this embodiment, the increase in the number of abnormal currents may mean that there are unstable factors in the flow state of the microchannel medium in the first monitoring subchannel. These unstable factors will interfere with the accuracy of the stability evaluation, making it difficult for the evaluation result to truly reflect the actual flow state of the microchannel medium; the increase in the number of abnormal currents may also indicate that there are potential fault risks in the microchannel medium in the first monitoring subchannel. These faults may include medium leakage, channel blockage, equipment damage, etc., affecting the normal operation of the microchannel.

[0084] It is the real-time risk assessment impact factor corresponding to the number of abnormal currents predefined in the microchannel medium database.

[0085] The real-time risk assessment impact factor corresponding to the number of abnormal currents is directly extracted from the microchannel medium database, and is expressed as a numerical value of the degree of influence on the real-time risk assessment index of the microchannel medium passing through the first monitoring subchannel during the process of the stability assessment of the microchannel medium passing through the first monitoring subchannel. In the microchannel medium database, there is a specific mapping relationship between the number of abnormal currents and the real-time risk assessment impact factor, and this mapping relationship can be in a one-to-one or many-to-one form. By substituting the number of abnormal currents detected in real time into the mapping set, the corresponding real-time risk assessment impact factor can be obtained. In this process, the number of abnormal currents is used as input, and the real-time risk assessment impact factor is used as output. The connection between the two is established through the mapping set. In this embodiment, the value range of the real-time risk assessment impact factor corresponding to the number of abnormal currents is (0, 1).

[0086] In a microchannel, there is a direct proportional relationship between the medium flow rate and the medium flow rate. Specifically, when the cross-sectional area of ​​the microchannel is constant, the greater the medium flow rate, the greater the flow rate. However, when the medium flow rate and the medium flow rate are too large and deviate from the reference values ​​of the flow rate and flow rate preset in the microchannel, it may cause the medium to generate strong turbulence in the microchannel, affecting the flow state of the medium in the channel, thereby increasing the risk of medium circulation; if the medium flow rate and the medium flow rate are too small and also deviate from the reference values ​​of the flow rate and flow rate preset in the microchannel, it may cause the medium to flow slowly in the microchannel, increase the residence time of the medium in the microchannel, and also affect the stability of the microchannel medium and increase the risk; when the medium flow rate increases, it leads to an increase in the flow rate, which in turn causes an increase in the pressure on the microchannel. This means that under the same channel size and medium properties, the greater the flow rate, the greater the pressure on the channel, and the pressure that the microchannel can withstand is limited. Excessive pressure will lead to the possibility of leakage in the microchannel, so the pressure also needs to be within a certain range to maintain the stability of the medium in the microchannel and reduce the risk of medium circulation.

[0087] The real-time risk assessment index of the microchannel medium passing through the first monitoring subchannel is matched with the stability assessment index corresponding to each predefined real-time risk assessment index interval. The specific matching process is: obtaining a mapping set between the real-time risk assessment index of the microchannel medium passing through the first monitoring subchannel and the stability assessment index from a microchannel medium database, determining the specific interval of the real-time risk assessment index of the microchannel medium passing through the first monitoring subchannel, and allocating the stability assessment index corresponding to the interval to the microchannel medium corresponding to the real-time risk assessment index passing through the first monitoring subchannel, thereby obtaining the stability assessment index of the microchannel medium passing through the first monitoring subchannel.

[0088] The second monitoring subchannel determination module is used to execute the risk control plan for the microchannel medium passing through the second monitoring subchannel, thereby obtaining the state data of the microchannel medium passing through the second monitoring subchannel and determining the stability evaluation index of the microchannel medium in the second monitoring subchannel.

[0089] Furthermore, the state data of the microchannel medium passing through the second monitoring subchannel specifically includes the maximum pressure value borne by the second monitoring subchannel during the second passing cycle, the medium temperature of the microchannel medium at each second passing time point, the starting time point of the microchannel medium passing through the second monitoring subchannel, the ending time point of the microchannel medium passing through the second monitoring subchannel, and the average current generated by the microchannel medium during the second passing cycle.

[0090] The above-mentioned second passing time points are specifically several second passing time points obtained by evenly dividing the second passing period into time points, and the corresponding division rule can be 30 seconds, wherein the second passing period refers to a period of time for the microchannel medium to pass through the second monitoring subchannel, and the second passing period is determined from the time when the microchannel medium starts to pass through the second monitoring subchannel to the time when all microchannel media leave the second monitoring subchannel, and the duration from the start time point of the microchannel medium passing through the second monitoring subchannel to the end time point of the microchannel medium passing through the second monitoring subchannel is the second passing period corresponding to the microchannel medium passing through the second monitoring subchannel, which is expressed as the circulation time of the microchannel medium through the second monitoring subchannel.

[0091] The above pressure value can be monitored by a pressure sensor, the medium temperature can be monitored by a temperature sensor, the start time point and the end time point can be monitored by a timer, and the current value can be monitored by a current sensor.

[0092] Specifically, the determination of the stability evaluation index of the microchannel medium in the second monitoring subchannel is carried out in the following specific determination process:

[0093] The medium temperature of the microchannel medium at each second passing time point is processed with a standard deviation to obtain a medium temperature stability coefficient of the microchannel medium in the second passing cycle.

[0094] The end time point of the microchannel medium passing through the second monitoring subchannel and the start time point of the microchannel medium passing through the second monitoring subchannel are subjected to difference processing to obtain the flow time length of the microchannel medium passing through the second monitoring subchannel.

[0095] According to the stability evaluation index of the microchannel medium passing through the first monitoring subchannel, the circulation reference time corresponding to the stability evaluation index interval of each first monitoring subchannel predefined in the microchannel medium database is matched. The specific matching process is: obtaining a mapping set of the stability evaluation index of the microchannel medium passing through the first monitoring subchannel and the circulation reference time from the microchannel medium database, determining the specific interval of the stability evaluation index of the microchannel medium passing through the first monitoring subchannel, and obtaining the circulation reference time corresponding to the interval, thereby obtaining the circulation reference time of the microchannel medium passing through the second monitoring subchannel.

[0096] The number of abnormal currents of the microchannel medium in the first monitoring subchannel is matched with the risk impact coefficients corresponding to the predefined abnormal current number intervals. The specific matching process is: obtaining a mapping set of the number of abnormal currents of the microchannel medium in the first monitoring subchannel and the risk impact coefficient from a microchannel medium database, determining a specific interval of the number of abnormal currents of the microchannel medium in the first monitoring subchannel, obtaining the risk impact coefficient corresponding to the interval, and thereby obtaining the risk impact coefficient of the microchannel medium in the second monitoring subchannel.

[0097] The generated current reference value is extracted from the microchannel medium database.

[0098] According to the maximum pressure value borne by the second monitoring subchannel in the second passing cycle, the medium temperature stability coefficient of the microchannel medium in the second passing cycle, the circulation time of the microchannel medium through the second monitoring subchannel, the risk impact coefficient of the microchannel medium in the second monitoring subchannel, and the average current generated by the microchannel medium in the second passing cycle, a comprehensive analysis is performed to obtain the stability evaluation index of the microchannel medium in the second monitoring subchannel. The specific method is as follows:

[0099] ;

[0100] In the formula, It is a stability evaluation index of the microchannel medium in the second monitoring subchannel. In this embodiment, it is used to measure the stability and reliability of the medium when the microchannel medium passes through the second monitoring subchannel. The higher the stability evaluation index of the microchannel medium passing through the second monitoring subchannel, the higher the stability and reliability of the medium when flowing through the second monitoring subchannel, and the lower the possibility of risk in the subsequent circulation of the microchannel medium in the monitoring subchannel.

[0101] It is the maximum pressure value that the second monitoring subchannel withstands in the second passing cycle, which means that when the microchannel medium flows through the second monitoring subchannel, the second monitoring subchannel needs to withstand the maximum pressure generated by the medium flow.

[0102] Adaptation value for pressure resistance.

[0103] is the medium temperature stability coefficient of the microchannel medium in the second passing cycle, which refers to the degree of fluctuation of the medium temperature when the microchannel medium flows through the second monitoring subchannel in the second passing cycle.

[0104] It is the risk impact coefficient of the microchannel medium in the second monitoring subchannel, which refers to a quantitative indicator of the risk impact that may be generated on the system or process when the microchannel medium flows in the second monitoring subchannel.

[0105] The flow time length of the microchannel medium through the second monitoring subchannel refers to the time length from when the microchannel medium starts to pass through the second monitoring subchannel to when the microchannel medium leaves the second monitoring subchannel.

[0106] The reference duration for circulation refers to the pre-set adaptation duration for medium circulation.

[0107] It is the average current generated by the microchannel medium in the second passing cycle, which refers to the average value of the electrical signal generated in the microchannel due to medium flow, chemical reaction, electrochemical reaction or physical process such as thermoelectric effect, piezoelectric effect, etc. in the second passing cycle of the microchannel medium.

[0108] To generate a current reference value, it refers to the pre-set adaptation value corresponding to the current generated by the medium.

[0109] It is represented by the stability assessment influencing factor corresponding to the medium temperature stability coefficient predefined in the microchannel medium database, It is expressed as the stability assessment impact factor corresponding to the risk impact coefficient predefined in the microchannel medium database, and e is a natural constant.

[0110] The stability assessment influence factor corresponding to the medium temperature stability coefficient and the stability assessment influence factor corresponding to the risk influence coefficient are directly extracted from the microchannel medium database, and are expressed as numerical values ​​of the degree of influence on the stability assessment index of the microchannel medium passing through the second monitoring subchannel during the stability assessment of the microchannel medium passing through the second monitoring subchannel. In the microchannel medium database, for example, there is a specific mapping relationship between the medium temperature stability coefficient and the stability assessment influence factor, and this mapping relationship can be in a one-to-one or many-to-one form. By substituting the medium temperature stability coefficient detected in real time into the mapping set, the corresponding stability assessment influence factor can be obtained. In this process, the medium temperature stability coefficient is used as input and the stability assessment influence factor is used as output. The connection between the two is established through the mapping set. In this embodiment, the value range of the stability assessment influence factor corresponding to the medium temperature stability coefficient and the stability assessment influence factor corresponding to the risk influence coefficient is (0, 1).

[0111] In this embodiment, when the medium temperature stability coefficient is larger, it means that the temperature change of the medium is larger during the circulation process, resulting in a more unstable flow state of the medium, so that the microchannel needs to withstand a larger pressure to buffer the negative impact of temperature changes. If the pressure value that the microchannel needs to withstand is much higher than the pre-set pressure reference value of the microchannel, the possibility of medium leakage, channel performance degradation and other hazards in the microchannel is greatly increased, thereby reducing the stability of the microchannel medium through the second monitoring subchannel; the circulation time of the medium in the channel may affect its temperature stability. For example, long-term circulation may cause the medium temperature to gradually increase or decrease, thereby affecting the temperature stability coefficient, and the circulation time of the medium in the channel may also affect the interaction between the medium and the channel wall, such as chemical reactions, adsorption, desorption and other processes. These processes may affect the ion concentration and charge distribution in the medium, thereby changing the current value generated by the medium, causing the current generated by the medium to deviate from its preset reference value, thereby greatly reducing the stability of the microchannel medium.

[0112] In this embodiment, the size of the risk impact coefficient directly reflects the instability factor of the microchannel medium in the second monitoring subchannel. The higher the coefficient, the greater the potential risk, which may lead to an increased sensitivity of the stability evaluation index to small disturbances, thereby reducing the stability of the microchannel medium in the second monitoring subchannel. At the same time, in a higher-risk environment, due to the large number of potential unstable factors, the stability evaluation index may be more susceptible to interference or misleading, thereby reducing its reliability; in summary, a larger risk impact coefficient of the microchannel medium in the second monitoring subchannel has a significant negative impact on the stability evaluation index of the microchannel medium in the second monitoring subchannel.

[0113] The risk control plan control module is used to compare the stability evaluation index of the microchannel medium in the second monitoring subchannel with the stability evaluation index of the microchannel medium through the first monitoring subchannel, and obtain and determine whether to adjust the risk control plan based on the medium stability evaluation comparison result.

[0114] Furthermore, the determination of whether to adjust the risk control plan is made based on the medium stability evaluation comparison result, and the specific determination process is as follows:

[0115] The stability assessment index of the microchannel medium in the second monitoring subchannel is differenced with the stability assessment index of the microchannel medium through the first monitoring subchannel to obtain the microchannel medium stability assessment index difference, and compared with the medium stability assessment difference allowable range predefined in the microchannel medium database. If the microchannel medium stability assessment index difference belongs to the medium stability assessment difference allowable range, there is no need to adjust the risk control plan. If the microchannel medium stability assessment index difference does not belong to the medium stability assessment difference allowable range, it is necessary to adjust the risk control plan.

[0116] It should be explained that when the difference in the stability evaluation index of the microchannel medium belongs to the permitted range of the medium stability evaluation difference, whether the difference is positive or negative, it is regarded as a permitted state. This setting is derived from the core goal of the embodiment of the present invention, that is, to ensure that the microchannel medium maintains a stable state when circulating in the channel, thereby effectively reducing the potential risks in the medium circulation process. Specifically, there is a certain fluctuation between the stability evaluation index of the microchannel medium in the second monitoring subchannel and the stability evaluation index when passing through the first monitoring subchannel, which is a reasonable and acceptable phenomenon. In summary, the above fluctuations are all within the preset reasonable range, aiming to ensure the safety and stability of the medium circulation.

[0117] Specifically, the risk control plan is regulated by regulating the risk control plan when the microchannel medium stability assessment index difference is greater than the maximum value of the medium stability assessment difference allowable interval or the microchannel medium stability assessment index difference is less than the minimum value of the medium stability assessment difference allowable interval.

[0118] If the difference in the microchannel medium stability evaluation index is greater than the maximum value of the medium stability evaluation difference allowable range, it means that the stability evaluation index of the microchannel medium in the second monitoring sub-channel fluctuates more than the stability evaluation index of the microchannel medium through the first monitoring sub-channel, which may cause abnormal fluctuations in the pressure, medium flow rate or medium temperature of the microchannel, affecting the normal operation of the entire microchannel medium flow.

[0119] If the difference in the stability assessment index of the microchannel medium is lower than the minimum value of the allowable range of the medium stability assessment difference, it means that after the risk control plan is implemented on the microchannel medium through the second monitoring sub-channel, not only the expected good effect is not achieved, but it may have an adverse effect on the stability of the microchannel medium, causing the stability assessment index of the medium in the second monitoring sub-channel to show a lower level.

[0120] When the difference in the microchannel medium stability assessment index is greater than the maximum value of the allowable range of the medium stability assessment difference, the risk control plan is adjusted by adjusting the power of the medium delivery pump to reduce the flow rate of the medium, thereby reducing the circulation time of the medium, and ultimately reducing the stability assessment index of the microchannel medium in the second monitoring sub-channel.

[0121] When the difference in the stability assessment index of the microchannel medium is less than the minimum value of the allowable range of the medium stability assessment difference, the risk control plan can be adjusted by setting a pressure regulating device in the microchannel, such as a throttle valve, a pressure sensor, etc., which can monitor and adjust the pressure distribution in the channel in real time. By adjusting the working state of these devices, the pressure distribution in the microchannel can be accurately controlled, so that the pressure in the microchannel is always kept within the range of the reference pressure, thereby increasing the stability assessment index of the microchannel medium in the second monitoring sub-channel.

[0122] The above contents are merely examples and explanations of the structure of the present invention. The technicians in this technical field may make various modifications or additions to the specific embodiments described or replace them in a similar manner. As long as they do not deviate from the structure of the invention or exceed the scope defined by the present invention, they should all fall within the protection scope of the present invention.
