[0057] Example

[0058] This invention provides a method for analyzing coal conveying based on belt conveyor warnings, such as... Figure 1 As shown, it includes:

[0059] S1, Obtain the current warning information of the coal conveyor belt, and determine the coal conveying capacity of the coal conveyor belt based on the current warning information.

[0060] S2, determine the specifications of the coal conveyor belt, and based on the coal conveying capacity, determine the coal height of the coal conveyor belt according to the specifications.

[0061] S3, obtain the belt warning information of the coal conveyor belt, the belt warning information includes belt tear warning information and belt misalignment warning information, determine the amount of coal leakage of the coal conveyor belt based on the belt tear warning information, and determine the amount of coal misalignment of the coal conveyor belt based on the belt misalignment warning information.

[0062] S4. Determine the coal conveying status in the coal conveyor belt based on the coal height, the amount of coal leakage, and the amount of coal deviation.

[0063] In some embodiments of this application, the current warning information is improved, and the current warning information includes a current threshold and a real-time current value.

[0064] In this embodiment, a warning message will be issued when the current of the coal conveyor belt exceeds the current threshold. The current threshold refers to the rated current of the coal conveyor belt. When the real-time current value is greater than the current threshold, the power increases, which may damage the belt belt. Therefore, a warning message is issued to warn the user.

[0065] In some embodiments of this application, a specific method for determining the coal conveying capacity of the coal conveying belt is disclosed, wherein a preset current difference matrix E0 is set, and E0(E1, E2, E3, E4) is defined, wherein E1 is the first preset current difference, E2 is the second preset current difference, E3 is the third preset current difference, E4 is the fourth preset current difference, and E1 < E2 < E3 < E4.

[0066] A preset coal conveying quantity matrix D0 is defined as D0(D1, D2, D3, D4), where D1 is the first preset coal conveying quantity, D2 is the second preset coal conveying quantity, D3 is the third preset coal conveying quantity, and D4 is the fourth preset coal conveying quantity, and D1 < D2 < D3 < D4.

[0067] Obtain the current threshold and real-time current value from the current warning information, determine the current difference e between the current threshold and the real-time current value, and set the coal conveying capacity of the coal conveying belt according to the relationship between the current difference e and each preset current difference.

[0068] When e < E1, the first preset coal conveying capacity D1 is set as the coal conveying capacity of the coal conveying belt.

[0069] When E1≤e<E2, the second preset coal conveying capacity D2 is set as the coal conveying capacity of the coal conveying belt.

[0070] When E2≤e<E3, the third preset coal conveying capacity D3 is set as the coal conveying capacity of the coal conveying belt.

[0071] When E3≤e<E4, the fourth preset coal conveying capacity D4 is set as the coal conveying capacity of the coal conveying belt.

[0072] In this embodiment, the current of the coal conveyor belt is related to the load of the coal conveyor belt. The greater the load of the coal conveyor belt, the greater the current. The coal conveying capacity of the coal conveyor belt can also be determined according to the load of the coal conveyor belt. Therefore, the present invention determines the coal conveying capacity of the coal conveyor belt based on the current difference between the current threshold and the real-time current value.

[0073] In some embodiments of this application, the specifications of the coal conveyor belt have been improved to facilitate the determination of the belt area of ​​the coal conveyor belt, the specifications of which include belt length and belt width.

[0074] In some embodiments of this application, determining the coal height of the conveyor belt based on the coal conveying capacity and the specified parameters includes:

[0075] The belt length a and belt width b in the specifications of the coal conveyor belt are determined, and the belt area s of the coal conveyor belt is determined based on the belt length a and belt width b, wherein the belt area s = a * b.

[0076] Obtain the ratio between the coal conveying capacity and the belt area s, and determine the coal height of the coal conveying belt based on the ratio.

[0077] In this embodiment, the coal height of the conveyor belt is the average height. Since the coal is irregularly shaped and its size is not fixed, the average height of the coal is used to represent its height in this invention. Regarding the belt area of ​​the conveyor belt, since the belt length *a* and belt width *b* are known, it can be calculated using the area formula for a rectangle. If multiple conveyor belts work together to transport coal, the connections between the belts can be ignored, and the area formula (length multiplied by width) can be directly used to determine the belt area of ​​the conveyor belt.

[0078] In some embodiments of this application, a specific method for determining the coal height of a coal conveyor belt is disclosed, wherein a preset ratio matrix R0 is set, and R0(R1, R2, R3, R4) is defined, wherein R1 is a first preset ratio, R2 is a second preset ratio, R3 is a third preset ratio, R4 is a fourth preset ratio, and R1 < R2 < R3 < R4.

[0079] A preset coal height matrix H0 is defined as H0(H1, H2, H3, H4), where H1 is the first preset coal height, H2 is the second preset coal height, H3 is the third preset coal height, and H4 is the fourth preset coal height, and H1 < H2 < H3 < H4.

[0080] After determining the i-th preset coal conveying amount Di as the coal conveying amount of the coal conveying belt according to the current difference e between the current threshold and the real-time current value in the current warning information, i = 1, 2, 3, 4; obtain the ratio r between the coal conveying amount and the belt area s, and set the coal height of the coal conveying belt according to the relationship between the ratio r and each preset ratio.

[0081] The ratio r is calculated according to the following formula: r = Di / s.

[0082] When r < R1, the first preset coal height H1 is set as the coal height of the coal conveyor belt.

[0083] When R1≤r<R2, the second preset coal height H2 is set as the coal height of the coal conveyor belt.

[0084] When R2≤r<R3, the third preset coal height H3 is set as the coal height of the coal conveyor belt.

[0085] When R3≤r<R4, the fourth preset coal height H4 is set as the coal height of the coal conveyor belt.

[0086] In this embodiment, since it is known that the ratio between the belt area of ​​the coal conveyor and the coal conveying capacity and the belt area is directly proportional to the coal height of the coal conveyor, the larger the ratio, the larger the coal height. Therefore, this invention determines the coal height of the coal conveyor by the ratio between the coal conveying capacity and the belt area.

[0087] In some embodiments of this application, determining the amount of coal leakage from the coal conveyor belt based on the belt tear warning information includes:

[0088] A pressure sensor is installed at the bottom of the coal conveyor belt, and the pressure sensor is used to detect the pressure difference.

[0089] The pressure difference detected by the pressure sensor is determined based on the belt tear warning information.

[0090] The amount of coal leakage from the coal conveyor belt is determined based on the pressure difference.

[0091] In this embodiment, when the belt tears, coal will fall from the belt into the bottom of the coal conveyor. Therefore, pressure sensors are evenly installed at intervals on the bottom of the belt of the coal conveyor. When the belt tears, coal will fall through the tear and onto the pressure sensor. Therefore, when the pressure difference of the pressure sensor changes, it indicates that the belt has torn. The greater the tear, the more coal falls, and the greater the pressure difference change value of the pressure sensor. Since the coal falling from the moving belt will not only fall at the same point, the pressure difference value can be determined by the distance between the pressure difference change value of the pressure sensor and the pressure sensor that detected the pressure difference change value. Then, the amount of coal leakage from the coal conveyor is determined by the pressure difference value.

[0092] In some embodiments of this application, a specific method for determining the amount of coal leakage from a coal conveyor belt is disclosed. A preset pressure difference matrix P0 is defined, and P0(P1, P2, P3, P4) is set, where P1 is the first preset pressure difference, P2 is the second preset pressure difference, P3 is the third preset pressure difference, P4 is the fourth preset pressure difference, and P1 < P2 < P3 < P4.

[0093] A preset coal leakage amount matrix L0 is defined as L0(L1, L2, L3, L4), where L1 is the first preset coal leakage amount, L2 is the second preset coal leakage amount, L3 is the third preset coal leakage amount, and L4 is the fourth preset coal leakage amount, and L1 < L2 < L3 < L4.

[0094] Determine the pressure difference p detected by the pressure sensor, and set the coal leakage amount of the coal conveyor belt according to the relationship between the pressure difference p and each preset pressure difference value.

[0095] When p < P1, the first preset coal leakage amount L1 is set as the coal leakage amount of the coal conveyor belt.

[0096] When P1≤p<P2, the second preset coal leakage amount L2 is set as the coal leakage amount of the coal conveyor belt.

[0097] When P2≤p<P3, the third preset coal leakage amount L3 is set as the coal leakage amount of the coal conveyor belt.

[0098] When P3≤p<P4, the fourth preset coal leakage amount L4 is set as the coal leakage amount of the coal conveyor belt.

[0099] In this embodiment, the pressure difference p represents the weight of the falling coal. Therefore, the pressure difference is directly proportional to the amount of coal leakage from the coal conveyor belt. The larger the pressure difference, the more coal is leaked. Therefore, this invention determines the amount of coal leakage from the coal conveyor belt by using the pressure difference.

[0100] In some embodiments of this application, the method for determining the coal deviation amount of a coal conveyor belt is improved. The method for determining the coal deviation amount of the coal conveyor belt based on the belt deviation warning information includes:

[0101] The belt misalignment warning information includes the belt offset of the coal conveyor belt.

[0102] The belt offset is set as the coal deviation of the coal conveyor belt.

[0103] In this embodiment, the coal is transported by a belt conveyor. Therefore, the coal moves in the same direction as the belt. So when the belt of the coal conveyor deviates, the coal will also deviate. Therefore, the present invention sets the belt deviation as the coal deviation of the coal conveyor.

[0104] This invention also discloses a coal conveying analysis system based on belt conveyor warnings, such as... Figure 2 As shown, it includes:

[0105] The acquisition module is used to acquire current warning information and belt warning information of the coal conveyor belt, including belt tear warning information and belt misalignment warning information.

[0106] The processing module is used to analyze the coal material on the coal conveyor belt based on the current warning information and the belt warning information, and obtain the analysis results.

[0107] The determination module is used to determine the coal conveying status in the coal conveyor belt based on the analysis results.

[0108] The processing module stores the specifications of the coal conveyor belt. It is used to determine the coal conveying capacity of the conveyor belt based on the current warning information; determine the coal height of the conveyor belt based on the specified specifications; determine the coal leakage amount based on the belt tear warning information; and determine the coal deviation amount based on the belt misalignment warning information. The determining module is used to determine the coal conveying status of the conveyor belt based on the coal height, the coal leakage amount, and the coal deviation amount.
