Description

Technical Field

[0001] The invention relates to a correction method, in particular to a method for identifying and automatically correcting the furnace numbers of four major cars of a coke oven, and belongs to the technical field of electrical equipment control. Background Art

[0002] The four large coke oven vehicles mainly set working points at the center line of the carbonization chamber during the coking production process, and rely on the identified furnace number position to perform chain coke pushing and environmentally friendly coal adding operations in the large workshop. When using the continuous absolute address recognition method to identify and locate the furnace number, the vehicle determines its position based on the absolute address of its own vehicle, and accepts the absolute address information of the collaborative vehicle for collaborative operation. Only when all vehicles reach the set position can they perform independent or collaborative operations in the carbonization chamber area to avoid safety and environmental accidents. In the early stage of coke oven production, the width of the coke oven carbonization chamber is relatively uniform, and the center line of each carbonization chamber has a fixed absolute address value L corresponding to it on the address detection equipment, such as Figure 1 As shown in the figure, each carbonization chamber is not affected by the deformation of the furnace body such as thermal expansion and contraction, and its carbonization chamber width W = W 1 =W 2 ..., so as long as the vehicle reaches the absolute address value L set by each 1 , L 2 The working point of the vehicle can be aligned with the center line position of the 1# or 2# carbonization chamber. The coke oven trolley control system determines whether the vehicle has reached the predetermined center line position of the carbonization chamber by reading the absolute address value, and sends its own absolute address value to other vehicles for subsequent chained collaborative operations. Since the vehicle receives the absolute address value, if these address values ​​are directly used for the chain control of itself and the collaborative operation, it is not easy for the operation and maintenance personnel to understand, and the position relationship between the vehicles cannot be more intuitively displayed in the monitoring system.

[0003] At the same time, with the influence of thermal expansion and contraction in the later stage of coke oven production and the influence of furnace aging, the position of each carbonization chamber will have different expansion and contraction changes, and the width of the carbonization chamber will no longer be equal, that is, W 1 ≠W 2 ≠W 3 …, so that the absolute address value corresponding to the center line of each carbonization chamber will also change, such as Figure 2 As shown in the figure, the absolute address value corresponding to the actual center line position of each carbonization chamber is represented by L 1 , L 2 etc. respectively change to L 1 ', L 2', etc. In order to ensure that the working point of the vehicle can still be aligned with the center line of the carbonization chamber during the automatic running and alignment process, technical personnel are required to regularly conduct professional measurement and maintenance of the vehicle's address control system, and manually correct the absolute address value corresponding to the center line position of each carbonization chamber in the control system. With the acceleration of the volume change of the coke oven body, the frequency of modifying the absolute address value of the center line of each carbonization chamber in the control system will become higher and higher, which will not only affect the normal production of the coke oven vehicle, but also lead to an increase in the system maintenance cost. Therefore, a new solution is urgently needed to solve the above technical problems. Summary of the invention

[0004] The present invention is aimed at the problems existing in the prior art and provides a method for identifying and automatically correcting the furnace numbers of four large cars of a coke oven. The scheme includes a set of coke oven carbonization chamber position correction devices and a method for identifying furnace numbers and automatically correcting addresses. Through the application of the scheme, the furnace number positions of each vehicle of the coke oven can be identified, and the automatic correction of the address of the coke oven car can be quickly achieved without frequently adjusting the address value parameters of the positioning control system, thereby ensuring the efficient and safe operation of the four large car system of the coke oven.

[0005] In order to achieve the above object, the technical solution of the present invention is as follows: a method for identifying and automatically correcting the furnace numbers of four major coke oven cars, the method comprising the following steps:

[0006] Step 1: Design a coke oven carbonization chamber position correction device. The position correction device includes a coke oven trolley positioning detection point and a detector. The detection points are arranged along the travel direction of the trolley and are installed at the center of the carbonization chamber door to align with the center lines of each carbonization chamber of the coke oven. The detector is installed on the vehicle and moves with the vehicle. During the movement of the vehicle, the detector will pass through these detection points and identify the signals of these detection points. Each time the center line of a carbonization chamber is passed, the detection point signal will be detected and the signal will be sent to the vehicle-mounted address control system. At the same time, the control system reads the absolute address value of the vehicle at that moment.

[0007] Step 2: Identify the position and range of the coke oven number, and establish a database corresponding to the oven number, absolute value and address range in the vehicle address control system. The vehicle control system sets the range of the carbonization chamber and the working area according to the signal and absolute address value of the oven area sampling point, and translates the absolute address into easy-to-understand continuous oven number position information.

[0008] Step 3: Automatically check the center line address of the coke oven carbonization chamber. Each time the detector passes the detection point of the N# carbonization chamber, it will send an absolute value address sampling signal to the vehicle control system. The vehicle address control system will record the new absolute value address L of the N# carbonization chamber. n ', due to the small offset of the carbonization chamber, L n’ will compare with the absolute value of the original center line address of the carbonization chamber to confirm whether the vehicle has shifted from the center line of the carbonization chamber. If e < |L n ’ - L n |, where e is the allowable deviation of the center line of the carbonization chamber and w is the shortest distance between the center lines of the carbonization chambers, it indicates that the center line of the carbonization chamber has shifted beyond the allowable deviation range. The address control system of the vehicle will replace the absolute value L n of the center line of the N# carbonization chamber in the address database with L n ’.

[0009] Step 4: Verify the absolute address by accumulating the number of detection points and automatically correct the carbonization chamber range.

[0010] Suppose the absolute address values of the center lines of the (N - 2)# carbonization chamber, (N - 1)# carbonization chamber, and N# carbonization chamber in the address database are respectively modified to L n-2 ’, L n-1 ’, and L n ’. Then, the calculation formula for automatically calculating the address range R n-1 of the vehicle in the (N - 1)# carbonization chamber area is (L n-1 ’ + L n-2 ’) / 2 ≤ R n-1 < (L n ’ + L n-1 ’) / 2, that is, when the vehicle detects that the new absolute address is between (L n-1 ’ + L n-2 ’) / 2 and (L n ’ + L n-1 ’) / 2, it can be determined that the working position of the vehicle is in the (N - 1)# carbonization chamber area.

[0011] Compared with the prior art, the present invention has the following advantages. The solution includes a coke oven carbonization chamber position correction device and a method for furnace number identification and automatic address correction. Through the application of this solution, it is possible to identify the furnace number positions of each vehicle in the coke oven, and quickly achieve automatic address correction of the coke oven large vehicle without frequently adjusting the address value parameters of the alignment control system, ensuring the efficient and safe operation of the four major vehicles system of the coke oven. By continuously detecting each detection point through the vehicle address control system and correcting the original absolute address value, it is possible to automatically correct the position of the center line of the carbonization chamber, ensure that the coke oven vehicle can accurately stop at the center line position of the carbonization chamber, and according to the corresponding table of furnace number, absolute value, and address range, automatically identify the absolute address as a continuous furnace number value that can be understood by the controllable operation and maintenance personnel, and it can also be automatically modified along with the automatic address correction, reducing the maintenance cost of personnel.

[0018] In order to deepen the understanding of the present invention, the present embodiment is described in detail below with reference to the accompanying drawings.

[0019] Example 1: See Figure 3-Figure 5 A method for identifying and automatically correcting the furnace numbers of the four major coke oven cars. A coke oven carbonization chamber position correction device includes a coke oven car positioning detection point and a detector. Its structure and installation position are as follows Figure 3 As shown, the detection points are arranged along the traveling direction of the trolley. They can be installed at the center of the carbonization chamber door or adjusted manually to ensure that they are always aligned with the center lines of the carbonization chambers of the coke oven. The detector is installed on the vehicle and moves with the vehicle. During the movement of the vehicle, the detector will pass through these detection points and identify the signals of these detection points. Each time the center line of a carbonization chamber is passed, the detection point signal will be detected once and the signal will be sent to the vehicle address control system. At the same time, the control system reads the absolute address value of the vehicle at that moment. Since these detection points are always aligned with the center lines of each carbonization chamber, the absolute values ​​of the vehicle addresses corresponding to them in the continuous distance measurement system are also relatively fixed. An address database corresponding to these detection points and the absolute values ​​of the addresses is established in the vehicle address control system. That is, each time the detector passes through the detection points of 1#, 2#...(N-1)#, N# carbonization chambers, it will send an absolute address sampling signal to the vehicle control system. The address database of the vehicle address control system will record the absolute address L of the center lines of 1#, 2#...(N-1)#, N# carbonization chambers respectively. 1 , L 2 …L n-1 , L n Based on this, the lower value of the absolute address of the 1# carbonization chamber can be calculated as (L 1 +L 0 ) / 2, the high value is (L 1 +L 2 ) / 2, where L 0is the absolute value address of the center line of the starting 0# carbonization chamber, then the recognition range of the 1# carbonization chamber is (L 1 +L 0 ) / 2≤R 1 <(L 1 +L 2 ) / 2, the lower value of the absolute value address of the 2# carbonization chamber is (L 2 +L 1 ) / 2, the high value is (L 2 +L 3 ) / 2, then the recognition range of 2# carbonization chamber is (L 2 +L 1 ) / 2≤R 2 <(L 2 +L 3 ) / 2, and so on, the recognition range of N# carbonization chamber is (L N +L N-1 ) / 2≤R N <(L N +L N+1 ) / 2, where L N+1 It is the absolute value address of the center line of (N+1)# carbonization chamber.

[0020] For the non-carbonization chamber working area where the vehicle passes, in order to ensure the uniqueness of identifying the vehicle position, detection points are also set up where the vehicle is working or parked, such as Figure 4 The vehicle maintenance position, coal tower parking area and working position shown in the figure, when the vehicle stops and works at these positions, the detector samples the absolute value addresses of these positions through the monitoring points, which are L j , L m and L g By triggering these sampling points, the vehicle control system database samples the absolute value addresses of these sampling points, and the coverage of these positions can be calculated. For example, the center line of the maintenance position area is equipped with a detection point, and the width of the maintenance position area is W. j , then the absolute address range of the maintenance position area is L j -W j / 2≤R j <L j +W j / 2, the absolute value address range of the coal tower area is L m -W m1 ≤R m <L m +W m2 When monitoring the vehicle during its movement, the address control system can translate these absolute address values ​​into vehicle at the maintenance position, at the No. 1 carbonization chamber position, at the coal tower area, etc., which is convenient for monitoring personnel to understand and conduct vehicle chain monitoring. The corresponding table of furnace number, absolute value and address range is shown in Figure 5 As shown in the figure. An address database corresponding to these detection points and the absolute address is established in the address control system. According to the address database, the unique corresponding relationship between each detection point and the absolute address can be displayed. Therefore, the vehicle control system can find the theoretical position of the vehicle by detecting the signals of the monitoring points installed on the ground and compare it with the actually detected absolute address value to verify the reliability of the absolute address value.

[0021] The detection point and the corresponding absolute address value of the vehicle are relatively fixed. Each time the detector passes through the detection point of the N# carbonization chamber, it will send an absolute address sampling signal to the vehicle control system, and the address control system of the vehicle will record the new absolute address value L of the N# carbonization chamber. n ’ Since the offset of the carbonization chamber is small, L n ’ will be compared with the original absolute address value of the carbonization chamber center line to confirm whether the vehicle and the carbonization chamber center line have shifted. If e < |L n ’ - L n | < w, where e is the allowable deviation of the carbonization chamber center line and w is the shortest distance between the carbonization chamber center lines, it indicates that the carbonization chamber center line has shifted beyond the allowable deviation range. The address control system of the vehicle will replace the absolute value L of the N# carbonization chamber center line in the address database with L n ’ and the schematic diagram of the address database update is as shown in n (the address updates of 2# and N#). After determining that the vehicle and the carbonization chamber center line are offset, the vehicle control system automatically writes the new address into the address database and aligns with the corresponding carbonization chamber with the new absolute address value to achieve automatic address correction. Figure 6 As shown in the figure. After determining that the vehicle and the carbonization chamber center line are offset, the vehicle control system automatically writes the new address into the address database and aligns with the corresponding carbonization chamber with the new absolute address value to achieve automatic address correction.

[0022] The address control system can also verify the absolute address value by accumulating the number of detection points according to the correspondence table between the furnace number and the absolute value. The method is as follows: Install N + 2 detection points starting from the starting point of the absolute address measurement range. The monitoring point number corresponding to the starting bit L of the absolute address is 0#, and the monitoring point number corresponding to L 0 is 1#, and so on until the monitoring point number corresponding to the end bit L of the absolute address is (N + 1)#. When the vehicle travels from the starting bit to the end bit, the control system collects the direction signal of the vehicle. When the vehicle travels forward, it will accumulate by one for each detection point passed, and when the vehicle travels backward, it will subtract one for each detection point passed. When the accumulated pulse quantity of the vehicle traveling to the detection point is N, it indicates that it has entered the area of the N# carbonization chamber. According to the correspondence table, the sampled address value should satisfy (L 1 + L n+1 ) / 2 ≤ R n < (L n-1 ) / 2 ≤ R n < (L n + Ln+1 ) / 2, otherwise it indicates that the absolute value address system is abnormal, and an alarm is output or the vehicle is stopped for maintenance.

[0023] In order to realize the automatic correction of the absolute value of the carbonization chamber area, after the absolute value address of the center line of the carbonization chamber is automatically modified, the address control system can automatically calculate the address range of each carbonization chamber area based on the new address database for the vehicle to identify its own position. The method is as follows: the absolute value addresses of the center lines of (N-2)#carbonization chamber, (N-1)#carbonization chamber and N#carbonization chamber in the address database are respectively modified to L n-2 ', L n-1 ' and L n ', then calculate the vehicle's address range R in the (N-1)# carbonization chamber area n-1 The calculation formula is L n-1 '-(L n-1 '-L n-2 ') / 2≤R n-1 <L n-1 '+(L n '-L n-1 ') / 2, which can also be converted to (L n-1 '+L n-2 ') / 2≤R n-1 <(L n '+L n-1 ') / 2, that is, the vehicle detects a new absolute value address at (L n-1 '+L n-2 ') / 2 and (L n '+L n-1 ') / 2, it can be determined that the working position of the vehicle is in the (N-1)# carbonization chamber area.

[0024] By continuously detecting and correcting the original absolute address value of each detection point through the vehicle address control system, the position of the center line of the carbonization chamber can be automatically corrected to ensure that the coke oven vehicle can be accurately parked at the center line position of the carbonization chamber, and according to the corresponding table of furnace number, absolute value and address range, the absolute value address is automatically identified as a continuous furnace number value that can be understood by the controllable operation and maintenance personnel, and can also be automatically modified as the address is automatically corrected, reducing the maintenance cost of personnel.

[0025] Working process: Refer to Figure 1 — Figure 6 , a method for identifying and automatically correcting the furnace numbers of the four major coke oven cars, the method comprising the following steps:

[0026] Step 1: Design a coke oven carbonization chamber position correction device. The position correction device includes a positioning detection point and a detector for the coke oven trolley. The detection points are arranged along the running direction of the trolley and are installed at the center position of the carbonization chamber door to align with the center lines of each carbonization chamber of the coke oven. The detector is installed on the vehicle and moves with the vehicle. During the movement of the vehicle, the detector will pass through these detection points, identify the signals of these detection points, detect the signal of the detection point once every time it passes through the center line of a carbonization chamber, and send the signal into the on-vehicle address control system. At the same time, the control system reads the absolute address value of the vehicle at this moment.

[0027] Step 2: Identify and confirm the range of the coke oven number position. Establish a database corresponding to the coke oven number, absolute value, and address range in the on-vehicle address control system. The vehicle control system sets the ranges of the carbonization chamber and the working area according to the signals of the furnace area sampling points and the absolute address value, and translates the absolute address into continuous coke oven number position information for easy understanding.

[0028] Step 3: Automatically verify the address of the coke oven carbonization chamber center line. Every time the detector passes through the detection point of the N# carbonization chamber, it will send an absolute address sampling signal to the vehicle control system. The address control system of the vehicle will record the new absolute address L n ’ of the N# carbonization chamber. Due to the small offset of the carbonization chamber, L n ’ will be compared with the absolute value of the original carbonization chamber center line address to confirm whether the vehicle and the carbonization chamber center line are offset. If e < |L n ’ - L n | < w, where e is the allowable deviation of the carbonization chamber center line and w is the shortest distance between the carbonization chamber center lines, it means that the carbonization chamber center line has deviated beyond the allowable deviation range. The address control system of the vehicle will replace the absolute value L n of the N# carbonization chamber center line in the address database with L n ’.

[0029] Step 4: Verify the absolute address by accumulating the number of detection points and automatically correct the carbonization chamber range.

[0030] Suppose the absolute address values of the center lines of the (N - 2)# carbonization chamber, (N - 1)# carbonization chamber, and N# carbonization chamber in the address database are modified to L n-2 ’, L n-1 ’, and L n ’ respectively. Then the formula for automatically calculating the address range R n-1 of the vehicle in the (N - 1)# carbonization chamber area is (L n-1 ’ + L n-2 ’) / 2 ≤ R n-1 < (L n ’ + L n-1 ’) / 2, that is, the vehicle detects that the new absolute address is within (Ln-1 '+L n-2 ') / 2 and (L n '+L n-1 ') / 2, it can be determined that the working position of the vehicle is in the (N-1)# carbonization chamber area.

[0031] The specific embodiments are as follows:

[0032] In this embodiment, the coke oven carbonization chamber position correction device includes a coke oven trolley positioning detection point and a detector, and its structure and installation position are as follows: Figure 3 As shown, the detection point is installed at the center of the carbonization chamber furnace door with an iron block protrusion and arranged along the travel direction of the trolley. The detector is installed on the vehicle with induction. As the vehicle moves, the detector will pass through these detection points during the movement of the vehicle and generate an electrical pulse signal. The electrical pulse signal is sent to the vehicle-mounted address control system, and the control system reads the absolute address value of the vehicle at that moment.

[0033] Assume that the standard width of the carbonization chamber is 1200mm, and the absolute value address of the center line of the 1# carbonization chamber is 100000mm. Since these detection points are always aligned with the center lines of each carbonization chamber, the absolute value of the vehicle address corresponding to them in the continuous distance measurement system is also relatively fixed. An address database corresponding to these detection points and the absolute value of the address is established in the vehicle address control system, that is, each time the detector passes through the detection points of the 1#, 2#...(N-1)#, N# carbonization chambers, it will send an absolute value address sampling signal to the vehicle control system, and the address database of the vehicle address control system will record the absolute value address L of the center line of the 1#, 2#...(N-1)#, N# carbonization chambers respectively. 1 =100000mm, L 2 =101200mm…L n-1 , L n Based on this, the lower value of the absolute address of the 1# carbonization chamber can be calculated as (L 1 +L 0 ) / 2=99400mm, the height is (L 1 +L 2 ) / 2 = 100600 mm, where L 0 The absolute value address of the center line of the starting 0# carbonization chamber is 98800mm, so the recognition range of the 1# carbonization chamber is 99400mm≤R 1 <100600mm, and so on, we can get Figure 5 The control system can translate the carbonization chamber furnace address and other working point furnace addresses according to the received real-time address absolute value and the corresponding table, and display the location of the vehicle in the 1# carbonization chamber, 2# carbonization chamber and coal tower to the upper computer.

[0034] When the coking chamber is offset, for example, the displacement of the 1# coking chamber is +10 mm in the positive direction and the displacement of the 2# coking chamber is -10 mm in the negative direction, and the allowable deviation of the coking chamber center line is e = 5 mm, and the shortest distance between the coking chamber center lines is w = 1200 mm, then the vehicle's address control system will record the new absolute address L of the 1# coking chamber 1 ’ = 100010 mm, L 2 ’ = 101190 mm. According to the judgment condition e < |L n ’ - L n | < w, for the 1# coking chamber, 5 mm < |100010 - 100000| < 1200 mm, for the 2# coking chamber, 5 mm < |101190 - 101200| < 1200 mm, which indicates that the center lines of the 1# and 2# coking chambers have deviated beyond the allowable deviation range. The vehicle's address control system will replace the absolute value L of the N# coking chamber center line in the address database with L n ’, and the schematic diagram of the address database update is as shown in n Figure 6 shown

[0035] The address control system can also verify the address absolute value by accumulating the number of detection points according to the correspondence table between the furnace number and the absolute value. The method is as follows: Install N + 2 detection points starting from the starting point of the absolute address measurement range. The monitoring point number corresponding to the starting bit L of the absolute address is 0#, and the monitoring point number corresponding to L 0 is 1#, and so on, until the monitoring point number corresponding to the end bit L of the absolute address is (N + 1)#. When the vehicle travels from the starting bit to the end bit, the control system collects the direction signal of the vehicle. When the vehicle travels forward, it will accumulate by adding one for each detection point passed, and when the vehicle travels backward, it will accumulate by subtracting one for each detection point passed. When the accumulated pulse amount of the vehicle reaches 2# at the detection point, it means entering the 2# coking chamber area. According to the correspondence table, the sampled address value should satisfy (L 1 + L n+1 ) / 2 ≤ R n < (L n-1 + L n < (L n + L n+1 ) / 2. Substituting the values in the correspondence table into the calculation, we get: (101190 + 100010) / 2 ≤ R 2 < (101190 + 102400) / 2, that is, the 2# coking chamber area is 100600 mm ≤ R 2 ​<101795mm, if the difference between the absolute value address value detected at the time of reading the detection point pulse and the address value in the database exceeds 1200mm or the current detected absolute value address value is not within the range of 100600mm and 101795mm, otherwise it means that the absolute value address system is abnormal, and an alarm output or parking for maintenance is performed.

[0036] In order to realize the automatic correction of the absolute value of the carbonization chamber area, after the absolute value address of the center line of the carbonization chamber is automatically modified, the address control system can automatically calculate the address range of each carbonization chamber area based on the new address database for the vehicle to identify its own position. The method is as follows: the absolute value addresses of the center lines of the 1# carbonization chamber, 2# carbonization chamber and 3# carbonization chamber in the address database are respectively modified to L 1 '=100010mm(positive deflection 10mm), L 2 '=101190mm(negative deflection 10mm) and L 3 '=102390mm (negative deflection 10mm), then calculate the new address range R of the vehicle in the (N-1)# carbonization chamber area n-1 The calculation formula is L n-1 '-(L n-1 '-L n-2 ') / 2≤R n-1 <L n-1 '+(L n '-L n-1 ') / 2, converted to (L n-1 '+L n-2 ') / 2≤R n-1 <(L n '+L n-1 ') / 2, for the 2# carbonization chamber, the original absolute address range of the vehicle is (L 2 +L 1 ) / 2 = (101200 + 100000) / 2 = 100600 mm and (L 2 +L 3 ) / 2 = (101200 + 102400) / 2 = 101800 mm. After correction, the absolute value address of the new 2# carbonization chamber is (L 2 '+L 1 ') / 2 = (100010 + 101190mm) / 2 = 100600mm and (L 2 '+L 3 ') / 2=(101190+102390) / 2=101790mm.

Suppose the absolute value addresses of the center lines of (N-2)#carbonization chamber, (N-1)#carbonization chamber, and N#carbonization chamber in the address database are modified to L n-2 ',L n-1 ' and L n ', then the vehicle address range R in (N-1)# carbonization chamber area is automatically calculated n-1 The calculation formula is (L n-1 '+L n-2 ') / 2≤R n-1 <(L n '+L n-1 ') / 2, that is, the vehicle detects a new absolute value address at (L n-1 '+L n-2 ') / 2 and (L n '+L n-1 ') / 2, it can be determined that the working position of the vehicle is in the (N-1)# carbonization chamber area.
