Since the processes of wiring the inner pot, connecting the water pipe, cleaning, and determining the test status are omitted, and there is no need to set up a separate integrated stove inner pot monitoring workstation, the online monitoring system of the integrated stove inner pot has the characteristics of simple operation, low cost and high flexibility, and solves the problems of cumbersome work and large floor space occupied by the existing integrated stove inner pot monitoring.

[0010] Optionally, the online monitoring system of the integrated stove inner pot further includes a fifth electromagnetic wave collector, and the fifth electromagnetic wave collector is arranged around the generator of the electromagnetic wave generating device.

[0011] Optionally, the frequency of the characteristic electromagnetic wave is greater than 430 THz.

[0012] Optionally, an electromagnetic wave shielding cover is also provided on the workstation.

[0013] Optionally, the online monitoring system of the integrated stove inner pot includes an electromagnetic wave collection module, and the electromagnetic wave collector transmits the time of the detected characteristic electromagnetic wave to the analysis module through the electromagnetic wave collection module.

[0014] The present invention also provides an online monitoring method for an integrated stove inner pot, which comprises the following steps:

[0015] Emitting electromagnetic waves to the inner pot of the integrated stove, so that when a hole appears in the inner pot of the integrated stove, characteristic electromagnetic waves generated at the hole are propagated to multiple electromagnetic wave collectors of the electromagnetic wave collector array;

[0016] Continuously detect the electromagnetic wave field through the electromagnetic wave collector and transmit the time of the detected characteristic electromagnetic wave to the analysis module;

[0017] A spatial rectangular coordinate system is constructed through the analysis module, coordinate values ​​of multiple electromagnetic wave collectors in the spatial rectangular coordinate system are obtained, and the coordinate value of the vulnerability is calculated based on the characteristic electromagnetic wave and the coordinate values ​​of multiple electromagnetic wave collectors in the spatial rectangular coordinate system.

[0018] Optionally, the plurality of electromagnetic wave collectors include a first electromagnetic wave collector, a second electromagnetic wave collector, a third electromagnetic wave collector and a fourth electromagnetic wave collector, and the specific method of continuously detecting the electromagnetic wave field by the electromagnetic wave collector and transmitting the time of the detected characteristic electromagnetic wave to the analysis module includes the following steps:

[0019] Synchronizing the time of the first electromagnetic wave collector, the second electromagnetic wave collector, the third electromagnetic wave collector, and the fourth electromagnetic wave collector;

[0020] Continuously detecting the electromagnetic wave field by using the first electromagnetic wave collector, the second electromagnetic wave collector, the third electromagnetic wave collector and the fourth electromagnetic wave collector;

[0021] When the first electromagnetic wave collector, the second electromagnetic wave collector, the third electromagnetic wave collector and the fourth electromagnetic wave collector detect the characteristic electromagnetic wave, the first electromagnetic wave collector, the second electromagnetic wave collector, the third electromagnetic wave collector and the fourth electromagnetic wave collector respectively transmit the times t1, t2, t3 and t4 of the characteristic electromagnetic waves detected by themselves to the analysis module.

[0022] Optionally, the specific method for calculating the coordinate value of the vulnerability by using the characteristic electromagnetic wave and the coordinate values ​​of the plurality of electromagnetic wave collectors in the spatial rectangular coordinate system includes the following:

[0024] The following spatial analytical equations (1), (2), (3), and (4) are established:

[0025] (x-x1) 2 +(y-y1) 2 +(z-z1) 2 =m 2 (1);

[0030] Subtracting equation (3) from equation (2) yields equation 2·(x·(x3-x2)+y·(y3-y2)+z·(z3-z2)+m·c·(t 13 -t 12 ))=α2;

[0031] Subtracting equation (4) from equation (3) yields equation 2·(x·(x4-x3)+y·(y4-y3)+z·(z4-z3)+m·c·(t 14 -t 13 ))=α3;

[0032] Subtracting equation (1) from equation (4) yields equation 2·(x·(x1-x4)+y·(y1-y4)+z·(z1-z4)-m·c·t 14 ) = α4;

[0033] Transform the equation 2·(x·(x2-x1)+y·(y2-y1)+z·(z2-z1)+m·c·t 12 )=α1, 2·(x·(x3-x2)+y·(y3-y2)+z·(z3-z2)+m·c·(t 13 -t 12 ))=α2, 2·(x·(x4-x3)+y·(y4-y3)+z·(z4-z3)+m·c·(t 14 -t 13 )) = α3 and 2·(x·(x1-x4)+y·(y1-y4)+z·(z1-z4)-m·c·t 14 )=α4 is converted into matrix form to obtain the matrix equation

[0034] Calculate the coordinate value S (x, y, z) of the vulnerability according to the matrix equation;

[0035] Where m is the distance from the electromagnetic wave sensor in the first electromagnetic wave collector to the vulnerability, c is the electromagnetic wave propagation speed, t 12 =t2-t1, t 13 =t3-t1, t 14 =t4-t1,α1=(x2 2 -x12 )+(y2 2 -y1 2 )+(z2 2 -z1 2 )-(c·t 12 ) 2 , α2=(x3 2 -x2 2 )+(y3 2 -y2 2 )+(z3 2 -z2 2 )+(c·t 12 ) 2 -(c·t 13 ) 2 , α3=(x4 2 -x3 2 )+(y4 2 -y3 2 )+(z4 2 -z3 2 )+(c·t 13 ) 2 -(c·t 14 ) 2 ,α4=(x1-x4)+(y1-y4)+(z1-z4)+(c·t 14 ).

[0045] In order to make the purpose, technical solution and advantages of the present invention more clearly understood, the present invention is further described in detail below in conjunction with its embodiments. It should be understood that the specific implementation methods described herein are only used to explain the present invention and do not limit the protection scope of the present invention.

[0046] It should be noted that when an element is referred to as being "fixed to" another element, it may be directly on the other element or there may be a central element. When an element is considered to be "connected to" another element, it may be directly connected to the other element or there may be a central element at the same time. The terms "vertical", "horizontal", "left", "right" and similar expressions used herein are for illustrative purposes only and do not represent the only implementation method.

[0047] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as those commonly understood by those skilled in the art of the present invention. The terms used herein in the specification of the present invention are only for the purpose of describing specific embodiments and are not intended to limit the present invention. The term "and / or" used herein includes any and all combinations of one or more related listed items.

[0048] The “first” and “second” mentioned in the present invention do not represent specific quantities and orders, but are merely used to distinguish names.

[0049] like Figure 1 As shown, the online monitoring system for the integrated stove inner pot in one embodiment of the present invention includes an electromagnetic wave collector array, an electromagnetic wave generating device and an analysis module.

[0050] The electromagnetic wave collector array includes a plurality of electromagnetic wave collectors, and the electromagnetic wave collectors are used to continuously detect the electromagnetic wave field and transmit the time of the detected characteristic electromagnetic wave to the analysis module.

[0051] Preferably, the plurality of electromagnetic wave collectors each include an electromagnetic wave signal receiving device, a protective housing and an installation panel. The electromagnetic wave signal receiving device is installed on the installation panel, and the protective housing is fixed on the installation panel and sleeved on the outside of the electromagnetic wave signal receiving device.

[0052] The electromagnetic wave signal receiving device includes a timer, an electromagnetic wave sensor, a controller, a mounting plate, a small antenna, a wireless module and a filter; the small antenna is parabolic and can gather electromagnetic waves; the mounting plate is fixed in the small antenna; the timer, the electromagnetic wave sensor, the controller, the wireless module and the filter are all mounted on the mounting plate; the time signal interface of the timer is connected to the time input interface of the controller; the signal output interface of the electromagnetic wave sensor is connected to the signal input interface of the filter; the signal output interface of the filter is connected to the electromagnetic wave signal input interface of the controller; the communication interface of the wireless module is connected to the communication output interface of the controller. Since the specific structure of the electromagnetic wave signal receiving device belongs to the conventional technical means in this field, each component thereof can be obtained by looking up the relevant model in the reference book and purchased on the market, so its specific structure and principle are not repeated here.

[0053] The electromagnetic wave sensor in the electromagnetic wave collector continuously converts the detected electromagnetic wave signal into an electrical signal, which is then transmitted to the controller after passing through a filter.

[0054] The electromagnetic wave generating device E is used to emit electromagnetic waves to the inner pot of the integrated stove, so that when a hole S appears in the inner pot of the integrated stove, the characteristic electromagnetic wave generated at the hole S is transmitted to the electromagnetic wave collector array.

[0055] Specifically, when the electromagnetic wave generating device E generates electromagnetic waves toward the inner pot of the integrated stove, the characteristic electromagnetic waves generated at the hole S will propagate to the electromagnetic wave collector array closest to the hole S; the electromagnetic wave collector array serves as a characteristic array.

[0056] Since the electromagnetic wave generating device E is a modulator and can be purchased on the market, its specific structure and working principle will not be described in detail here.

[0057] The analysis module is used to construct a spatial rectangular coordinate system, obtain the coordinate values ​​of the multiple electromagnetic wave collectors in the spatial rectangular coordinate system, and calculate the coordinate value of the vulnerability S based on the characteristic electromagnetic wave and the coordinate values ​​of the multiple electromagnetic wave collectors in the spatial rectangular coordinate system.

[0058] The online monitoring system of the integrated stove inner pot is provided with an electromagnetic wave collector array, and the characteristic electromagnetic wave generated at the detected integrated stove inner pot leak S is fed back to the analysis module by the electromagnetic wave collector array, and the coordinate value of the leak S is calculated according to the characteristic electromagnetic wave and the coordinate values ​​of the multiple electromagnetic wave collectors in the spatial rectangular coordinate system, so that the integrated stove leak S can be detected. Since the processes of wiring the inner pot, connecting the water pipe, cleaning, and determining the test status are omitted, and there is no need to set up a separate integrated stove inner pot monitoring workstation, the online monitoring system of the integrated stove inner pot has the characteristics of simple operation, low cost and high flexibility, and solves the problems of cumbersome work and large floor space occupied by the existing integrated stove inner pot monitoring.

[0059] In one embodiment, if Figure 2 and Figure 3 As shown, the multiple electromagnetic wave collectors include a first electromagnetic wave collector A, a second electromagnetic wave collector B, a third electromagnetic wave collector C and a fourth electromagnetic wave collector D. The first electromagnetic wave collector A, the second electromagnetic wave collector B, the third electromagnetic wave collector C and the fourth electromagnetic wave collector D are all arranged around a workstation, and the workstation is used to place the integrated stove inner pot to be inspected. The first electromagnetic wave collector A is arranged opposite to the electromagnetic wave generating device E, and the second electromagnetic wave collector B, the third electromagnetic wave collector C and the fourth electromagnetic wave collector D are arranged between the first electromagnetic wave collector A and the electromagnetic wave generating device E.

[0060] Specifically, the electromagnetic wave sensors in the first electromagnetic wave collector A, the second electromagnetic wave collector B, the third electromagnetic wave collector C and the fourth electromagnetic wave collector D continuously convert the detected electromagnetic wave signals into electrical signals, and transmit them to the controller after passing through the filter.

[0061] The central axis of the electromagnetic wave sensor of the first electromagnetic wave collector A is the same as the entry and exit direction of the integrated stove inner pot on the workstation.

[0062] The online monitoring system of the integrated stove inner pot includes an electromagnetic wave collection module, and the electromagnetic wave collector transmits the time of the detected characteristic electromagnetic wave to the analysis module through the electromagnetic wave collection module.

[0063] When the first electromagnetic wave collector A, the second electromagnetic wave collector B, the third electromagnetic wave collector C and the fourth electromagnetic wave collector D detect characteristic electromagnetic waves, the controllers in the first electromagnetic wave collector A, the second electromagnetic wave collector B, the third electromagnetic wave collector C and the fourth electromagnetic wave collector D respectively transmit the times t1, t2, t3 and t4 when they detect the characteristic electromagnetic waves to the analysis module through the corresponding electromagnetic wave collection modules.

[0064] When the integrated stove inner pot is moved to the work station, the side with the largest plane surface area of ​​the integrated stove inner pot is in contact with the conveyor belt. Because the side with the largest plane surface area of ​​the integrated stove inner pot is made of sheet metal, there will be no hole S. Through this design, the hole S is exposed in other spatial positions and is easier to be monitored.

[0065] In one of the embodiments, the online monitoring system of the integrated stove inner pot also includes a fifth electromagnetic wave collector, and the fifth electromagnetic wave collector is arranged around the generator of the electromagnetic wave generating device E.

[0066] Specifically, the fifth electromagnetic wave collector is arranged around the nozzle of the electromagnetic wave generating device E. The structure of the fifth electromagnetic wave collector is the same as that of other electromagnetic wave collectors. The fifth electromagnetic wave collector is used to obtain the electromagnetic wave generated noise and environmental noise of the electromagnetic wave generating device E, and cooperate with other electromagnetic wave collectors to eliminate the electromagnetic wave generated noise and environmental noise, so as to locate the position of the vulnerability S more accurately.

[0067] The time of the fifth electromagnetic wave collector is synchronized with the time of other electromagnetic wave collectors. At the same time, the high-frequency electromagnetic waves collected by the fifth electromagnetic wave collector are converted into digital signals through analog-to-digital conversion, and are superimposed with the digital signals obtained and converted by other electromagnetic wave collectors to eliminate noise and improve the accuracy of electromagnetic wave data.

[0068] In one of the embodiments, the frequency of the characteristic electromagnetic wave is greater than 430 THz (Tera Hertz), and an electromagnetic wave shielding cover 1 is also provided on the work station.

[0069] Specifically, if Figure 5As shown, the electromagnetic wave shielding cover 1 includes a door-type structure 10 with a through opening and two electromagnetic wave shielding plates 11 that seal the door-type structure. A bottom plate 12 that matches the door-type structure is provided on the workstation, and a conveyor belt 13 for driving the integrated stove inner pot to move is also provided on the bottom plate; the central axis of the through opening is the same as the in-and-out direction of the integrated stove inner pot on the workstation, the first electromagnetic wave collector A and the electromagnetic wave generating device E are respectively connected to the two opposite electromagnetic wave shielding plates, and a first avoidance position 14 and a second avoidance position 15 are opened on the door-type structure, the notch diameter of the first avoidance position is larger than the maximum outer diameter of the first electromagnetic wave collector A, and the notch diameter of the second avoidance position is larger than the maximum outer diameter of the electromagnetic wave generating device E and the fifth electromagnetic wave collector; the two electromagnetic wave shielding plates are also respectively connected with a first electromagnetic wave shielding cover plate and a second electromagnetic wave shielding cover plate for covering the first avoidance position and the second avoidance position; the two electromagnetic wave shielding plates are driven to move in the vertical direction by a crane. Through the above design, a sealed electromagnetic wave shielding environment can be formed without affecting the assembly line operation, thereby reducing the influence of external electromagnetic waves on the monitoring inside the electromagnetic wave shielding cover 1.

[0070] In one embodiment, the online monitoring system of the integrated stove inner pot further includes an alarm module, which is signal-connected to the analysis module. When a hole S is detected in the integrated stove inner pot, the alarm module issues an alarm to indicate that the integrated stove inner pot needs to be reworked.

[0071] Another embodiment of the present invention also provides an online monitoring method for an integrated stove inner pot, such as Figure 4 As shown, it includes the following steps:

[0072] S1, emitting electromagnetic waves to the inner pot of the integrated stove, so that when a hole S appears in the inner pot of the integrated stove, the characteristic electromagnetic waves generated at the hole S are propagated to multiple electromagnetic wave collectors of the electromagnetic wave collector array.

[0073] S2, continuously detecting the electromagnetic wave field through the electromagnetic wave collector and transmitting the time of the detected characteristic electromagnetic wave to the analysis module.

[0074] S3, constructing a spatial rectangular coordinate system through an analysis module, obtaining coordinate values ​​of multiple electromagnetic wave collectors in the spatial rectangular coordinate system, and calculating the coordinate value of the vulnerability S according to the characteristic electromagnetic wave and the coordinate values ​​of multiple electromagnetic wave collectors in the spatial rectangular coordinate system.

[0075] Since the relative positions of multiple electromagnetic wave collectors and the hole S in the integrated stove pot are different, and the propagation speed of the electromagnetic wave remains unchanged, the time difference between the electromagnetic wave signals received by the multiple electromagnetic wave collectors can be used to accurately locate the hole S in the integrated stove pot.

[0076] Taking advantage of the fact that electromagnetic waves passing through the hole S will produce characteristic electromagnetic waves with different frequencies from the electromagnetic waves of the structural holes, it is possible to accurately monitor whether there are holes S in the inner liner, greatly reducing the false detection rate.

[0077] That is to say, the online monitoring method of the integrated stove inner pot is provided with an electromagnetic wave collector array, and the characteristic electromagnetic wave generated at the detected integrated stove inner pot leak S is fed back to the analysis module by the electromagnetic wave collector array, and the coordinate value of the leak S is calculated according to the characteristic electromagnetic wave and the coordinate values ​​of the multiple electromagnetic wave collectors in the spatial rectangular coordinate system, which can realize the detection of the integrated stove leak S. Since the processes of wiring the inner pot, connecting the water pipe, cleaning and determining the test status are omitted, and there is no need to set up a separate integrated stove inner pot monitoring workstation, the online monitoring system of the integrated stove inner pot has the characteristics of simple operation, low cost and high flexibility, and solves the problems of cumbersome work and large floor space occupied by the existing integrated stove inner pot monitoring.

[0078] In one embodiment, the plurality of electromagnetic wave collectors include a first electromagnetic wave collector A, a second electromagnetic wave collector B, a third electromagnetic wave collector C and a fourth electromagnetic wave collector D. The specific method of continuously detecting the electromagnetic wave field by the electromagnetic wave collectors and transmitting the detected characteristic electromagnetic wave to the analysis module includes the following steps:

[0079] S20, synchronizing the time of the first electromagnetic wave collector A, the second electromagnetic wave collector B, the third electromagnetic wave collector C, and the fourth electromagnetic wave collector D.

[0080] Specifically, the timers in the first electromagnetic wave collector A, the second electromagnetic wave collector B, the third electromagnetic wave collector C, and the fourth electromagnetic wave collector D are synchronized. The electromagnetic wave sensors in the first electromagnetic wave collector A, the second electromagnetic wave collector B, the third electromagnetic wave collector C, and the fourth electromagnetic wave collector D continuously convert the detected electromagnetic wave signals into electrical signals and transmit them to the controller through the filter.

[0081] S21, continuously detecting the electromagnetic wave field through the first electromagnetic wave collector A, the second electromagnetic wave collector B, the third electromagnetic wave collector C and the fourth electromagnetic wave collector D.

[0082] When the electromagnetic wave generating device E generates electromagnetic waves toward the inner pot of the integrated stove, the characteristic electromagnetic waves generated at the hole S will propagate to the electromagnetic wave collector array closest to the hole S; the electromagnetic wave collector array serves as a characteristic array. When the first electromagnetic wave collector A, the second electromagnetic wave collector B, the third electromagnetic wave collector C, and the fourth electromagnetic wave collector D detect characteristic electromagnetic waves, the controllers in the first electromagnetic wave collector A, the second electromagnetic wave collector B, the third electromagnetic wave collector C, and the fourth electromagnetic wave collector D respectively transmit the times t1, t2, t3, and t4 when they detect the characteristic electromagnetic waves to the analysis module through the corresponding electromagnetic wave collection modules.

[0083] S22, when the first electromagnetic wave collector A, the second electromagnetic wave collector B, the third electromagnetic wave collector C and the fourth electromagnetic wave collector D detect the characteristic electromagnetic wave, the first electromagnetic wave collector A, the second electromagnetic wave collector B, the third electromagnetic wave collector C and the fourth electromagnetic wave collector D respectively transmit the times t1, t2, t3 and t4 of the characteristic electromagnetic waves detected by themselves to the analysis module.

[0084] In one embodiment, a specific method for calculating the coordinate value of the vulnerability S by using the characteristic electromagnetic wave and the coordinate values ​​of the plurality of electromagnetic wave collectors in the spatial rectangular coordinate system comprises the following steps:

[0085] S30, obtain the coordinate values ​​A(x1, y1, z1), B(x2, y2, z2), C(x3, y3, z3), and D(x4, y4, z4) of the first electromagnetic wave collector A, the second electromagnetic wave collector B, the third electromagnetic wave collector C, the fourth electromagnetic wave collector D, and the vulnerability S in the spatial rectangular coordinate system.

[0086] S31, establish the following spatial analytical equations (1), (2), (3), (4):

[0087] (x-x1) 2 +(y-y1) 2 +(z-z1) 2 =m 2 (1);

[0088] (x-x2) 2 +(y-y2) 2 +(z-z2) 2 =(m+(c·t 12 )) 2 (2);

[0089] (x-x3) 2 +(y-y3) 2 +(z-z3)2 =(m+(c·t 13 )) 2 (3);

[0090] (x-x4) 2 +(y-y4) 2 +(z-z4) 2 =(m+(c·t 14 )) 2 (4).

[0091] S32, subtract equation (2) from equation (1) to obtain equation 2·(x·(x2-x1)+y·(y2-y1)+z·(z2-z1)+m·c·t 12 ) = α1;

[0092] Subtracting equation (3) from equation (2) yields equation 2·(x·(x3-x2)+y·(y3-y2)+z·(z3-z2)+m·c·(t 13 -t 12 ))=α2;

[0093] Subtracting equation (4) from equation (3) yields equation 2·(x·(x4-x3)+y·(y4-y3)+z·(z4-z3)+m·c·(t 14 -t 13 ))=α3;

[0094] Subtracting equation (1) from equation (4) yields equation 2·(x·(x1-x4)+y·(y1-y4)+z·(z1-z4)-m·c·t 14 ) = α4;

[0095] Transform the equation 2·(x·(x2-x1)+y·(y2-y1)+z·(z2-z1)+m·c·t 12 )=α1, 2·(x·(x3-x2)+y·(y3-y2)+z·(z3-z2)+m·c·(t 13 -t 12 ))=α2, 2·(x·(x4-x3)+y·(y4-y3)+z·(z4-z3)+m·c·(t 14 -t 13 )) = α3 and 2·(x·(x1-x4)+y·(y1-y4)+z·(z1-z4)-m·c·t 14 )=α4 is converted into matrix form to obtain the matrix equation

[0096] S33, calculating the coordinate value S (x, y, z) of the vulnerability according to the matrix equation.

[0097] Where m is the distance from the electromagnetic wave sensor in the first electromagnetic wave collector A to the hole S, and c is the electromagnetic wave propagation speed, and the value of c is 3*10 8 m / s,t 12 =t2-t1, t 13 =t3-t1, t 14 =t4-t1,α1=(x2 2 -x1 2 )+(y2 2 -y1 2 )+(z2 2 -z1 2 )-(c·t 12 ) 2 , α2=(x3 2 -x2 2 )+(y3 2 -y2 2 )+(z3 2 -z2 2 )+(c·t 12 ) 2 -(c·t 13 ) 2 , α3=(x4 2 -x3 2 )+(y4 2 -y3 2 )+(z4 2 -z3 2 )+(c·t 13 ) 2 -(c·t 14 ) 2 ,α4=(x1-x4)+(y1-y4)+(z1-z4)+(c·t 14 )
