[0017] See also Figure 1 , Figure 1 1 is a flow chart of a method for conveying pulverized coal applicable to a pulverized coal distributor provided in an embodiment of the present invention. In this embodiment, the pulverized coal conveying method is executed by a terminal device. It is understood that the types of terminal devices include but are not limited to mobile phones, tablet computers, notebook computers, ultra-mobile personal computers (Ultra-Mobile Personal Computer, UMPC), netbooks, personal digital assistants (Personal Digital Assistant, PDA), etc., and the embodiments of the present invention do not impose any restrictions on the specific types of terminal devices.

[0018] See also Figure 1 The coal powder conveying method applicable to the coal powder distributor provided in the embodiment of the present invention includes but is not limited to the following steps: In S100, the target output amount information of pulverized coal and the actual output amount information of pulverized coal corresponding to each output branch pipe are obtained.

[0019] Without loss of generality, the pulverized coal conveying method may be applied to a pulverized coal distributor, which includes a plurality of output branches, and the output branches are used to convey the pulverized coal.

[0020] Specifically, the terminal device can first obtain the target output amount information of coal powder corresponding to each output branch pipe, and at the same time obtain the measured output amount information of coal powder corresponding to each output branch pipe, wherein the target output amount information of coal powder is used to describe the current operating parameters of the coal powder distributor, that is, the target output amount of coal powder; the measured output amount information of coal powder is used to describe the measured output amount of coal powder for the output branch pipe, that is, the measured coal powder flow rate corresponding to the output branch pipe.

[0021] In S200, for each output branch pipe, it is determined whether the measured output amount information of the pulverized coal is less than the target output amount information of the pulverized coal.

[0022] Specifically, after the terminal device obtains the target output amount information of the pulverized coal and the measured output amount information of the pulverized coal, the terminal device can perform the processing for each output branch: determine whether the measured output amount information of the pulverized coal is less than the target output amount information of the pulverized coal.

[0023] In S300, if the measured output amount information of the pulverized coal is less than the target output amount information of the pulverized coal, an air flow rate increase instruction is generated.

[0024] Specifically, if the measured coal powder output information is less than the coal powder target output information, the terminal device can generate an air flow increase instruction, wherein the air flow increase instruction is used to increase the air flow of the output branch pipe, that is, to increase the air flow of the output branch pipe.

[0025] In some possible implementations, in order to generate an air flow increase instruction, before step S300, the method further includes but is not limited to the following steps: In S301, the measured air flow information of the output branch pipe is obtained.

[0026] Specifically, the terminal device may first obtain the measured air flow information of the output branch pipe, wherein the measured air flow information is used to describe the measured air flow of the output branch pipe.

[0027] Accordingly, see Figure 2 Step S300 includes but is not limited to the following steps: In S310, if the measured output amount information of the pulverized coal is less than the target output amount information of the pulverized coal, the preset maximum value information of the air flow rate is obtained.

[0028] Specifically, if the measured coal powder output information is less than the coal powder target output information, the terminal device can obtain the preset maximum air flow rate information, where the maximum air flow rate information is used to describe the maximum air flow rate allowed for the flow output branch under the premise of meeting the current working requirements.

[0029] In S320, the upward adjustment range information is generated based on the difference between the maximum air flow rate information and the measured air flow rate information.

[0030] Specifically, the terminal device can generate the upward adjustment range information based on the difference between the maximum air flow information and the measured air flow information, wherein the minimum value of the upward adjustment range information is the measured air flow information, and the maximum value of the upward adjustment range information is the maximum air flow information.

[0031] In S330 , the upward adjustment range information is divided into equal parts according to the preset upward adjustment number information to generate a plurality of upward adjustment sub-range information.

[0032] Specifically, after the terminal device generates the upward adjustment range information, the terminal device may divide the upward adjustment range information into equal parts according to the preset upward adjustment number information to generate multiple upward adjustment sub-range information, wherein the multiple upward adjustment sub-range information constitute the upward adjustment range information.

[0033] In S340 , air flow rate increase instruction set information is generated according to the maximum values ​​corresponding to the respective increase sub-range information.

[0034] Specifically, after the terminal device generates multiple upward sub-range information, the terminal device can generate air flow upward instruction set information based on the maximum value corresponding to each upward sub-range information, wherein the air flow upward instruction set information includes multiple air flow upward instructions, and the air flow corresponding to each air flow upward instruction is not the same.

[0035] In S400, the pulverized coal distributor is controlled according to the air flow rate increase instruction.

[0036] Specifically, after the terminal device generates an air flow increase instruction, the terminal device can control the pulverized coal distributor according to the air flow increase instruction, thereby achieving real-time adjustment of operating parameters according to the specific working conditions of the output branch pipe during the pulverized coal transportation process, effectively improving reliability.

[0037] In some possible implementations, to effectively improve reliability, see Figure 3 Step S400 includes but is not limited to the following steps: In S410, the pulverized coal distributor is controlled according to the first air flow rate increase instruction to increase the pulverized coal target output information.

[0038] Specifically, the terminal device may first control the pulverized coal distributor according to the first air flow increase instruction to adjust the pulverized coal target output information, wherein the first air flow increase instruction may be the air flow increase instruction with the smallest air flow in the air flow increase instruction set information.

[0039] In S420, the target output amount information of pulverized coal and the measured output amount information of pulverized coal corresponding to each output branch are acquired in a loop, and for each output branch, it is determined whether the measured output amount information of pulverized coal is less than the target output amount information of pulverized coal.

[0040] Without loss of generality, when there is coal powder blockage inside the output branch pipe, the measured coal powder output information will be less than the coal powder target output information, and increasing the air flow, that is, the ventilation volume can help restore the flow inside the output branch pipe. Therefore, after adjusting the coal powder target output information on the terminal device, the terminal device can cyclically execute the above steps S100 and S200.

[0041] In S430, if the actual measured output information of the coal powder is less than the target output information of the coal powder, the coal powder distributor is controlled according to the second air flow increase instruction to adjust the target output information of the coal powder until each air flow increase instruction is executed, or the actual measured output information of the coal powder is equal to the target output information of the coal powder.

[0042] Specifically, if the measured output information of coal powder is less than the target output information of coal powder, it means that after the air flow rate is increased, there is still coal powder blockage inside the output branch pipe. Therefore, the terminal device can control the coal powder distributor according to the second air flow increase instruction to further increase the target output information of coal powder, thereby further increasing the air flow rate, and further helping to restore the flow inside the output branch pipe until the terminal device has executed each air flow increase instruction, or the measured output information of coal powder is equal to the target output information of coal powder; wherein, the operating condition corresponding to the terminal device having executed each air flow increase instruction is that even if the target output information of coal powder is increased to the maximum air flow information, there is still coal powder blockage inside the output branch pipe; the operating condition corresponding to the measured output information of coal powder being equal to the target output information of coal powder is that after the target output information of coal powder is increased, the blockage of coal powder inside the output branch pipe is resolved.

[0043] Without loss of generality, the air flow corresponding to the second air flow increase instruction is greater than the air flow corresponding to the first air flow increase instruction.

[0044] In some possible implementations, in order to help maintenance personnel know the specific coal powder blockage situation inside the output branch pipe, please refer to Figure 4 , the measured output amount information of the pulverized coal is less than the target output amount information of the pulverized coal, then after step S400, the method further includes but is not limited to the following steps: In S500, the execution frequency information of the air flow rate increase instruction is obtained.

[0045] Specifically, the terminal device may first obtain the execution count information of the air flow rate increase instruction, wherein the execution count information is used to describe the execution count of the air flow rate increase instruction.

[0046] In S510, it is determined whether the execution count information is less than or equal to a preset first execution count threshold.

[0047] Specifically, after the terminal device obtains the execution count information, the terminal device may determine whether the execution count information is less than or equal to a preset first execution count threshold.

[0048] In S520 , if the execution number information is less than or equal to the first execution number threshold, light congestion information is generated.

[0049] Specifically, if the execution number information is less than or equal to the first execution number threshold, the terminal device may generate light blockage information, wherein the light blockage information is used to describe the existence of light coal powder blockage inside the output branch pipe.

[0050] In S530, if the execution count information is greater than the first execution count threshold, it is determined whether the execution count information is less than or equal to a preset second execution count threshold.

[0051] Specifically, if the execution count information is greater than a first execution count threshold, the terminal device may determine whether the execution count information is less than or equal to a preset second execution count threshold, wherein the second execution count threshold is greater than the first execution count threshold.

[0052] In S540 , if the execution number information is less than or equal to the second execution number threshold, medium congestion information is generated.

[0053] Specifically, if the execution number information is less than or equal to the second execution number threshold, the terminal device may generate moderate blockage information, wherein the moderate blockage information is used to describe the existence of moderate coal powder blockage inside the output branch pipe.

[0054] In S550 , if the execution number information is greater than the second execution number threshold, severe congestion information is generated.

[0055] Specifically, if the execution number information is greater than the second execution number threshold, the terminal device may generate severe blockage information, wherein the severe blockage information is used to describe the situation that there is severe coal powder blockage inside the output branch pipe.

[0056] In some possible implementations, in order to enable data tracing when the same blocking situation occurs later, please refer to Figure 5 If severe congestion information is generated, then after step S400, the method further includes but is not limited to the following steps: In S600, the preset measured humidity information of the pulverized coal is obtained, and the accumulated operation time information of the output branch pipe is obtained.

[0057] Specifically, the terminal device can first obtain the preset coal powder measured humidity information and obtain the cumulative operating time information of the output branch pipe, wherein the coal powder measured humidity information is used to describe the measured humidity of the coal powder, and the cumulative operating time information is used to describe the cumulative operating time of the output branch pipe. The cumulative operating time information can be the cumulative operating time of the coal powder distributor.

[0058] In S610, the measured humidity information of the pulverized coal, the accumulated operation time information and the severe blockage information are uploaded to the designated remote server.

[0059] Specifically, after the terminal device obtains the measured humidity information of the pulverized coal and the accumulated operating time information, the terminal device may upload the measured humidity information of the pulverized coal, the accumulated operating time information and the severe blockage information to a designated remote server.

[0060] The implementation principle of the coal powder conveying method applicable to the coal powder distributor in the embodiment of the present invention is: the terminal device can first obtain the coal powder target output information and the coal powder actual output information corresponding to each output branch pipe, and then perform the processing for each output branch pipe: determine whether the coal powder actual output information is less than the coal powder target output information; if the coal powder actual output information is less than the coal powder target output information, the terminal device can accurately generate an air flow increase instruction; finally, according to the air flow increase instruction, the coal powder distributor is effectively controlled, thereby realizing real-time adjustment of operating parameters according to the specific working conditions of the output branch pipe, greatly improving reliability.
