Description

Technical Field

[0001] The present application relates to the technical field of safety protection, and in particular, to a safety protection method, device, equipment and medium for a fuel transmission belt. Background Art

[0002] The coal conveying belt in a power plant production undertakes the important task of conveying fuel to the boiler and is an important equipment in the coal conveying system. However, it is quite common that the belt is scratched by sharp objects such as a coal plow and falling parts of a material guiding trough, a baffle falling off in a coal unloading trough, a lining plate falling from a coal dropping pipe, an iron piece sucked out by a magnetic separator, and an iron piece in coal during operation. If the scratch on the belt during operation cannot be detected and disposed of in time, it will cause long-distance scratches on the belt, affecting the normal transmission of coal and thus the normal operation of the factory.

[0003] The current monitoring means mainly include manual inspection, video monitoring, infrared belt break protection and pull wire type belt break protection. However, the manual inspection and video monitoring means have obvious limitations and it is difficult to find the fault point. The limitations of the infrared belt break protection and the pull wire type belt break protection are that if the coal leakage is small after the belt is scratched or the scratch point is behind the protection device, the protection device cannot be triggered to operate to stop the coal conveying belt during coal leakage.

[0062] The present application will be further described in detail below with reference to the accompanying drawings.

[0063] An embodiment of the present application provides a safety protection method for a fuel transfer belt. The safety protection method for the fuel transfer belt can be executed by an electronic device, and the electronic device can be a server or a terminal device. The server can be an independent physical server, a server cluster or a distributed system composed of multiple physical servers, or a cloud server providing cloud computing services. The terminal device can be a smart phone, a tablet computer, a desktop computer, etc., but is not limited thereto.

[0064] Figure 1 It is a schematic flowchart of a safety protection method for a fuel transfer belt provided by an embodiment of the present application.

[0065] As Figure 1 shown, the main process of the method is described as follows (Steps S101 - S105):

[0066] Step S101, obtain the belt system to be managed and the operating load data and operating current data of the belt system to be managed.

[0067] In this embodiment, the belt system to be managed includes multiple belts that are connected and operate cooperatively. All the belts form a complete operating system, and this complete operating system is regarded as the belt system to be managed. When in use, data generated by the belt system to be managed is collected to obtain operating load data and operating current data. Here, both the operating load data and the operating current data are historical data, that is, the data is collected before calculation. The operating load data and the operating current data are relative combined data, that is, each time the belt system to be managed is in use, both data are collected. When retrieving the operating load data, the operating current data generated simultaneously with the operating load data can be retrieved at the same time, and vice versa. When retrieving the operating current data, the operating load data generated simultaneously with the operating current data can be retrieved at the same time.

[0068] Step S102: Generate current protection setting values based on the operating load data and the operating current data. Among them, the current protection setting values include no-load current protection setting values and full-load current protection setting values.

[0069] Regarding step S102, select the operating load data to obtain full-load operating data and no-load operating data; obtain the full-load current value corresponding to the full-load operating data and the no-load current value corresponding to the no-load operating data; obtain the protection setting value calculation strategy; calculate the full-load current protection setting value based on the full-load current value and the protection setting value calculation strategy; calculate the no-load current protection setting value based on the no-load current value and the protection setting value calculation strategy.

[0070] In this embodiment, after obtaining the operating load data, first select the operating load data, extract the data with the maximum load capacity and the data with no load capacity in the load data. The data with the maximum load capacity is used as the full-load operating data, and the data with no load capacity is used as the no-load operating data. According to the obtained full-load operating data and no-load operating data, the corresponding operating current data is obtained, resulting in full-load current data and no-load current data. Since the obtained full-load operating data and no-load operating data are both multiple, the obtained full-load current data and no-load current data are also both multiple. First, according to the protection setting value calculation strategy, select and calculate the full-load current data and the no-load current data to obtain the final full-load current value and no-load current value for calculation. The specific selection method is to select the maximum value of the full-load current data and the no-load current data and use the maximum value as the current value. It can also be to calculate the average value of all the full-load current data and use the average value of the full-load current as the full-load current value. Similarly, calculate the average value of all the no-load current data and use the average value of the no-load current as the no-load current value. The protection setting value calculation strategy is set with a calculation ratio value, and the protection setting values are calculated respectively according to the calculation ratio value, that is, calculate the product of the full-load current value and the calculation ratio value and the product of the no-load current value and the calculation ratio value, and use the obtained products as the full-load current protection setting value and the no-load current protection setting value.

[0071] Step S103: Obtain the belt number, belt position, and current carrying weight of the target belt in the belt system to be managed.

[0072] In this embodiment, according to the above content, there are multiple belts connected and operating cooperatively in the belt system to be managed. All the belts are numbered according to the conveying order of the coal material to obtain the belt number, and the position is described based on the conveying order and installation position to obtain the belt position. At the same time, the weight of the coal material on each belt is measured to obtain the current carrying position.

[0073] Step S104: Determine the working state of the target belt based on the belt number, belt position, and current carrying weight.

[0074] Regarding Step S104, determine whether the target belt is the end belt conveyor based on the belt number and belt position; if the target belt is the end belt conveyor, obtain the conveying information and current information of the previous belt conveyor of the target belt conveyor; determine the working state of the target belt based on the conveying information and current information; if the target belt is not the end belt conveyor, obtain the feeding time of the initial equipment; determine the working state of the target belt based on the feeding time.

[0075] In this embodiment, since both the belt number and belt position are set according to the transportation order, it is possible to directly determine whether the target belt is the end belt based on the belt number and belt position. Here, five belts are taken as an example, numbered #1, #2, #3, #4, and #5 respectively. Their belt numbers represent the transportation order. If it is #1 - #4, it will be determined as not the end belt conveyor. If it is #5, it will be determined as the end belt conveyor. Since the end belt conveyor is directly connected to the coal material using equipment, there may be problems such as coal material accumulation, and different calculations are needed to ensure the safety of the entire coal material use system and the belt itself, so different calculation methods are adopted. When the target belt is the end belt conveyor, collect the conveying information and current information of the previous belt conveyor. In the example, that is, collect the conveying information and current information of the #4 belt conveyor, and use the conveying information and current information to determine the working state of the target belt. When the target belt is not the end belt conveyor, obtain the feeding time of the initial equipment, that is, the feeding equipment, and determine the working state of the target belt according to the feeding time.

[0076] Further, determining the working state of the target belt based on the conveying information and the current information includes: obtaining the conveying threshold, the current threshold, and the anti-misoperation delay; calculating the delay time based on the conveying information and a pre-designed calculation formula; determining whether the target belt is in a full-load state based on the conveying information, the conveying threshold, the current information, and the current threshold; when the target belt is in a full-load state, generating a full-load working state based on the anti-misoperation delay; and in response to the shutdown operation of the staff, generating an empty-load working state based on the shutdown operation and the conveying information.

[0077] When the target belt is the end belt, collect the set conveying threshold current threshold and anti-misoperation delay. When the conveying information of the previous belt conveyor continuously exceeds the conveying threshold within a preset time, or the current information continuously exceeds the current threshold within a preset time, or both situations exist, calculate the duration. When the duration reaches the anti-misoperation delay, determine the working state of the target belt as the full-load loading state, and use the full-load current protection setting value to protect the target belt safely. For the empty-load working state, after the coal feeding is completed, after the monitoring personnel normally operate to stop the operation, switch to the empty-load working state.

[0078] Further, determining the working state of the target belt based on the feeding time includes: calculating the conveying time for the coal material to reach the target belt based on the feeding time; obtaining the anti-misoperation delay; generating a full-load working state based on the conveying time and the anti-misoperation delay; and in response to the shutdown operation of the staff, generating an empty-load working state based on the shutdown operation and the conveying information.

[0079] When the target belt is not the end belt, calculate the conveying time for the coal material to fall into the belt conveyor according to the feeding time, the conveying rate of each belt conveyor, and the belt conveying distance. When the current of the belt conveyor continuously is greater than or equal to the preset current threshold and after delaying the anti-misoperation delay, the target belt conveyor switches to the full-load working state. At the same time, in the same way as the end belt conveyor, for the empty-load working state, after the coal feeding is completed, after the monitoring personnel normally operate to stop the operation, switch to the empty-load working state.

[0080] In this embodiment, obtain the misoperation stop information and the corresponding transportation state of the misoperation stop information in real time; generate a switching reminder information based on the misoperation stop information and the transportation state; and send the switching reminder information to the mobile terminal of the staff to remind the staff to perform the state switching.

[0081] In special cases, such as when a person accidentally stops the coal conveyor belt during normal coal transportation, due to the operation of the person to stop it, it will automatically switch to the no-load current protection setting value. However, at this time, there is coal on the coal conveyor belt, and the on-load current protection setting value must be used. Or after the coal is loaded, it is not necessary to immediately stop the coal conveyor belt, and it is necessary to perform work such as no-load operation for the large interlock test, etc. The above situation is regarded as the accidentally touched stop information, and a switching reminder information is generated based on the transportation state when the accidentally touched operation stops, so that the operator can switch the current protection setting value according to the actual situation, that is, perform the state switching step S105, and perform safety protection on the belt system to be managed based on the working state and the target protection setting value.

[0082] In this embodiment, after obtaining the working state, switch to the corresponding target protection setting value according to the working state, and use the practical target protection setting value for safety protection. After the detected current value exceeds the target protection setting value, it will trip and stop operating, so as to quickly and accurately perform safety protection on each belt of the belt system to be managed.

[0083] In this embodiment, obtain the alarm adjustment strategy; calculate the alarm adjustment value based on the alarm adjustment strategy and the current protection setting value; generate the current alarm setting value based on the alarm adjustment value and the current protection setting value.

[0084] When using the current protection setting value for current protection, since tripping will be performed when the current protection setting value is exceeded, but the operator cannot know in advance and make preparations for direct tripping. Therefore, set the current alarm setting value, and give an alarm reminder when the current alarm setting value is reached to remind the operator to make corresponding handling. The alarm adjustment strategy is to set an adjustment ratio, calculate the product of the adjustment ratio and the current protection setting value, and use the product as the current alarm setting value.

[0085] It should be noted that in order to prevent the instantaneous current from being too large when the belt conveyor starts, resulting in misoperation of the overcurrent protection, each coal conveyor belt is allowed to trip and stop the belt when the current exceeds the set tripping value only after running for a preset time. Each coal conveyor belt has its own overcurrent protection setting value under no-load and full-load conditions, and can realize the automatic switching of no-load and full-load current protection setting values. Once the belt is scratched and the current rises abnormally, it can make a more timely and accurate fault judgment, give an alarm in time and quickly trip and stop the belt conveyor, and can play a protective role for the belt at the initial stage of being scratched.
