[0079] The technical solutions in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application.

[0080] In the following introduction, the terms "first" and "second" are used for descriptive purposes only and should not be understood as indicating or implying relative importance. The following introduction provides multiple embodiments of the present application, and different embodiments can be replaced or combined, so the present application can also be considered to include all possible combinations of the same and / or different embodiments recorded. Therefore, if one embodiment includes features A, B, and C, and another embodiment includes features B and D, then the present application should also be considered to include embodiments containing one or more of all other possible combinations of A, B, C, and D, although the embodiment may not be clearly recorded in the following text.

[0081] The following description provides examples and does not limit the scope, applicability or examples set forth in the claims. Changes may be made to the functions and arrangements of the elements described without departing from the scope of the present application. Various processes or components may be appropriately omitted, substituted or added to each example. For example, the described method may be performed in an order different from the order described, and various steps may be added, omitted or combined. In addition, features described in some examples may be combined in other examples.

[0082] See also Figure 1 , Figure 1 A flow chart of a method for controlling linkage of multiple boilers provided in an embodiment of the present application is shown.

[0083] like Figure 1 As shown, the method for controlling multiple boilers in linkage can control at least two boilers at the same time, and each boiler can be set similar to the parallel relationship in the circuit, and can be connected to each boiler separately through a controller but not limited to, so that the user can view or control each boiler on the controller, and the controller can control the operating status of each boiler at the same time. The method for controlling multiple boilers in linkage can at least include the following steps:

[0084] Step 102: Collect monitoring data from at least two sensors, and generate a report based on the monitoring data from at least two sensors.

[0085] This application will use the controller as the execution subject of one or more embodiments, and this application is not limited to this. Specifically, the controller can collect monitoring data from at least two sensors after being connected in parallel with at least two boilers. The at least two sensors can be, but are not limited to, used to obtain any at least two monitoring data of the boiler's steam flow data, steam pressure data, steam temperature data, or boiler load data, and the at least two sensors can be used to be set on any at least one of the at least two boilers. Among them, each sensor can obtain monitoring data at a preset time interval. Here, taking the temperature sensor used to monitor steam temperature data as an example, the temperature sensor can be controlled to obtain steam temperature data once every 10 seconds, and each steam temperature data obtained can be accompanied by a record of the corresponding acquisition time.

[0086] It can be understood that the at least two sensors here can be but are not limited to flow sensors, pressure sensors and temperature sensors, wherein the flow sensor can be used to obtain the steam flow monitoring data of the boiler, the pressure sensor can be used to obtain the steam pressure monitoring data of the boiler, and the temperature sensor can be used to obtain the steam temperature monitoring data of the boiler.

[0087] Further, after collecting the monitoring data of at least two sensors, the controller can generate a report based on the monitoring data of the at least two sensors. The report can be used to more intuitively view the overall monitoring data of the boiler within a preset time period, and the report can include types. Possibly, the type of the report can be a daily report, that is, all the monitoring data collected based on the same sensor in a day are summarized and displayed in the form of a chart. Here, it can be but not limited to collecting monitoring data once every hour, and 24 collected monitoring data in a day can be summarized to obtain a daily report. Possibly, the type of the report can be a weekly report, that is, all the monitoring data collected based on the same sensor in a week are summarized and displayed in the form of a chart. Here, it can be but not limited to summarizing all the collected monitoring data at intervals of one day, and seven summarized monitoring data in a week can be summarized again to obtain a weekly report. Possibly, the type of the report may be a monthly report, that is, all the monitoring data collected based on the same sensor within a month are summarized and displayed in the form of a chart, here, it can be but not limited to a weekly interval (or an interval of preset days, the embodiment of the present application is not limited thereto) All the collected monitoring data are summarized, and the four summarized monitoring data within a month can be summarized again to obtain a monthly report. Possibly, the type of the report may be a quarterly report, that is, all the monitoring data collected based on the same sensor within a quarter are summarized, and displayed in the form of a chart, here, it can be but not limited to a monthly interval All the monitoring data collected are summarized, and the three summarized monitoring data within a quarter can be summarized again to obtain a quarterly report. Possibly, the type of the report may also be an annual report, that is, all the monitoring data collected based on the same sensor within a year are summarized, and displayed in the form of a chart, here, it can be but not limited to a monthly interval All the monitoring data collected are summarized, and the four summarized monitoring data within a year can be summarized again to obtain an annual report.

[0088] It can also be understood that for the monitoring data collected by different types of sensors, corresponding reports can be generated respectively. For example, daily report 1 can be generated based on the steam flow monitoring data collected by the flow sensor, daily report 2 can be generated based on the steam pressure monitoring data collected by the pressure sensor, and daily report 3 can be generated based on the steam temperature monitoring data collected by the temperature sensor. It should be noted that when different types of reports need to be generated, the type of report can also be generated based on the monitoring data of multiple sensors in the same type of report. For example, the daily report can be generated based on the steam flow monitoring data A1 collected by the flow sensor, the steam pressure monitoring data B1 collected by the pressure sensor, and the steam temperature monitoring data C1 collected by the temperature sensor, the weekly report can be generated based on the steam flow monitoring data A2 collected by the flow sensor, the steam pressure monitoring data B2 collected by the pressure sensor, and the steam temperature monitoring data C2 collected by the temperature sensor, and the monthly report can be generated based on the steam flow monitoring data A3 collected by the flow sensor, the steam pressure monitoring data B3 collected by the pressure sensor, and the steam temperature monitoring data C3 collected by the temperature sensor.

[0089] Step 104: Determine whether at least two boilers are in working order according to the report.

[0090] Specifically, after generating the report, the controller can determine whether the at least two boilers are in working condition according to the monitoring data displayed in the report. Among them, when the monitoring data displayed in the report is not 0, it can be indicated that at least two boilers are currently in working condition. When the monitoring data displayed in the report is 0, it can be indicated that at least two boilers are not currently in working condition, which can correspond to the start-up state. It can be understood that when the monitoring data displayed in the report is 0, it can also indicate that at least two boilers are in a resting standby state at this time. Based on this, it can also be determined whether the at least two boilers are in a start-up state or a resting standby state by the trajectory corresponding to the monitoring data displayed in the report. The embodiments of the present application are not limited to this.

[0091] As an option, judging whether at least two boilers are in working state according to the report may further include:

[0092] Determine the type of report based on user actions;

[0093] Determining whether at least two boilers are in working state according to data corresponding to the type of the report;

[0094] When the data corresponding to the type of the report is 0, it is determined that at least two boilers are not in working state;

[0095] When the data corresponding to the type of the report is not 0, it is determined that at least two boilers are in operation.

[0096] Specifically, when judging whether the at least two boilers are in working state according to the report, the report type that meets the user's needs can be determined based on the user operation, wherein the user operation can be understood as the user can perform a selection operation on the display screen set on the controller, and the selection method can be but not limited to selecting the report type by checking the relevant instructions. Further, after determining the report type according to the user operation, it can be determined whether the at least two boilers are in working state by checking whether the monitoring data of the report is 0, and it can be but not limited to when the data corresponding to the type of the report is 0, it is determined that the at least two boilers are not in working state, and when the data corresponding to the type of the report is not 0, it is determined that the at least two boilers are in working state.

[0097] Step 106: When it is determined that at least two boilers are not in an operating state, control the at least two boilers according to monitoring data of at least two sensors.

[0098] Specifically, when the controller determines that at least two boilers are not in working state, the controller can control at least two boilers according to the monitoring data of at least two sensors collected previously, for example, the number of boilers to be turned on can be controlled separately, or the number of boilers to be turned on and the load ratio of each boiler to be turned on can be controlled simultaneously. The load ratio of the boiler can be understood as the ratio of the amount of data actually processed by the boiler to the amount of data processed by the rated amount. For example, the rated coal consumption of a boiler is 1 ton, and the load ratio is 80%, which means that the actual amount of coal processed by the boiler is 0.8 tons.

[0099] In an embodiment of the present application, the operating status of the boiler can be accurately determined by generating a report based on the monitoring data, and the boiler can be controlled in combination with the operating status and the monitoring data to ensure the control accuracy of multiple boilers during operation in real time, and can be applied to any operating status of the boiler to meet the user's control experience needs.

[0100] See also Figure 2 , Figure 2 A flow chart of another method for controlling linkage of multiple boilers provided in an embodiment of the present application is shown.

[0101] like Figure 2 As shown, the method for controlling multiple boilers in linkage may at least include the following steps:

[0102] Step 202: Collect monitoring data from at least two sensors, and generate a report based on the monitoring data from at least two sensors.

[0103] Specifically, step 202 may refer to step 102, which will not be described in detail here.

[0104] Step 204: Determine whether at least two boilers are in working order according to the report.

[0105] Specifically, step 204 may refer to step 104, which will not be described in detail here.

[0106] Step 206: When it is determined that at least two boilers are not in operation, determine whether the monitoring data of at least two sensors are zero.

[0107] Specifically, after determining that the at least two boilers are in the on state, the controller can determine whether the at least two boilers are in the cold state based on the monitoring data of the at least two sensors mentioned above. The cold state of the boiler can be understood as the state in which the boiler has not yet entered the working state after the on state, which can be determined by checking whether the monitoring data of the at least two sensors are 0. For example, but not limited to, when the at least two sensors are flow sensors, pressure sensors, and temperature sensors, the steam flow monitoring data collected by the flow sensor, the steam pressure monitoring data collected by the pressure sensor, and the steam temperature monitoring data collected by the temperature sensor can be checked respectively. If all the monitoring data are displayed as 0, it can be proved that the at least two boilers are in the cold state at this time; if there is any at least one monitoring data in all the monitoring data that is not 0, it can be proved that the at least two boilers are already in the working state at this time.

[0108] Step 208: When it is determined that the monitoring data of at least two sensors are 0, the number of the at least two boilers that are turned on is controlled to be half of the total number of the at least two boilers.

[0109] Specifically, after determining that the monitoring data of the at least two sensors is 0, the controller may control the number of the at least two boilers turned on to be half of the total number by default. For example, but not limited to, when the total number of the at least two boilers is 4, the number of boilers turned on may be controlled to be 2 by default, and the turned-on boilers may be any two of the total number. It is understandable that the at least two boilers may be quickly put into operation by controlling the number of boilers turned on to be half of the total number, and the operating efficiency of the at least two boilers may be guaranteed. It should be noted that when the total number of the at least two boilers is an odd number, the number of boilers turned on may be, but not limited to, half of the total number of the at least two boilers minus one by default, and the embodiments of the present application are not limited thereto.

[0110] See also Figure 3 , Figure 3 A flow chart of another method for controlling linkage of multiple boilers provided in an embodiment of the present application is shown.

[0111] like Figure 3 As shown, the method for controlling multiple boilers in linkage may at least include the following steps:

[0112] Step 302: Collect monitoring data from at least two sensors, and generate a report based on the monitoring data from at least two sensors.

[0113] Specifically, step 302 may refer to step 102, which will not be described in detail here.

[0114] Step 304: Determine whether at least two boilers are in working order according to the report.

[0115] Specifically, step 304 may refer to step 104, which will not be described in detail here.

[0116] Step 306: When it is determined that at least two boilers are in operation, heat data of the at least two boilers are determined based on monitoring data of boiler load sensors.

[0117] Specifically, when the controller determines that the at least two boilers are in working state, the controller can also determine the heat generated by the at least two boilers through the boiler load ratio collected by the boiler load sensor and the equipment parameters marked on the boiler. Among them, the equipment parameters marked on the boiler can be but not limited to the rated coal burning amount of the boiler, and in the embodiment of the present application, as a preference, the equipment parameters of each boiler can be kept consistent. It can be understood that after the controller determines the boiler load ratio and the rated coal burning amount of the boiler respectively, it can first calculate the actual coal burning amount of the at least two boilers according to the boiler load ratio and the rated coal burning amount of the boiler, and then convert the actual coal burning amount of the at least two boilers to obtain the corresponding heat.

[0118] Step 308: Perform fuzzy control calculation according to the type of report and the heat data of at least two boilers to obtain the load ratio of at least two boilers.

[0119] Specifically, after obtaining the heat of the at least two boilers, the controller can also perform automatic optimization fuzzy three-level closed-loop control operations according to the data corresponding to the determined report type and the heat of the at least two boilers to obtain the ideal load ratio of the at least two boilers. Among them, the data corresponding to the determined report type can be but not limited to the average value of the determined report type, and the report average value generated based on the monitoring data collected by each sensor is different. For example, taking the determined report type as a daily report as an example, the controller can take the average value of multiple daily reports generated within a preset time interval to obtain the average value of the daily report. It can be understood that after the controller obtains the above-mentioned report average value and the heat of the at least two boilers respectively, the report average value and the heat of the at least two boilers can be input into the fuzzy three-level automatic closed-loop control model, and the output result is used as the ideal load ratio of the at least two boilers. It can also be understood that the ideal load ratio of the at least two boilers can correspond to the ideal load ratio of each boiler. It is possible that the ideal load ratio of each boiler in the embodiment of the present application can be kept consistent, that is, the controller can simultaneously control the working state of each boiler. Possibly, in the embodiment of the present application, the ideal load ratio of each boiler may be different, that is, the controller may control the working state of each boiler individually.

[0120] Step 310: determine whether the monitoring data of at least two sensors is 0, and when it is determined that the detection data of at least two sensors is not 0, perform fuzzy control operation according to the monitoring data of at least two sensors and a preset first threshold to obtain the number of at least two boilers turned on.

[0121] Specifically, when the controller determines that the at least two boilers are not in the on state, it can continue to determine whether the at least two boilers are in the cold state, and when it determines that the at least two boilers are not in the cold state, it can perform automatic optimization fuzzy three-level closed-loop control operation based on the monitoring data collected by the at least two sensors and the preset first threshold value to obtain the ideal number of the at least two boilers to be turned on. The preset first threshold value can be determined according to the type of sensor, for example, but not limited to, when the sensor is a temperature sensor, the preset first threshold value can correspond to the preset temperature threshold value of the boiler steam; when the sensor is a pressure sensor, the preset first threshold value can correspond to the preset pressure threshold value of the boiler steam.

[0122] It should be noted that the automatic optimization fuzzy three-level closed-loop control operation mentioned in the embodiment of the present application may be a common technical means in the field and will not be elaborated here.

[0123] Step 312: Control at least two boilers based on the load ratio of the at least two boilers and the number of the at least two boilers that are turned on.

[0124] Specifically, after obtaining the ideal load ratio of the at least two boilers and the ideal number of boilers to be turned on, the controller can control the current number of the at least two boilers turned on according to the ideal number of boilers turned on, and control the load ratio of each boiler according to the ideal load ratio of the at least two boilers, so that the current number of the at least two boilers turned on is the ideal number of boilers turned on, and the load ratio of each boiler is the ideal load ratio. For example, when the current number of the at least two boilers turned on is 4 and the load ratio of each boiler is 80%, if the ideal load ratio of the at least two boilers is 75% and the ideal number of boilers turned on is 3, the controller can control the currently turned on 4 boilers to close at least one boiler, and adjust the load ratio of each boiler from 80% to 75%.

[0125] See also Figure 4 , Figure 4 A flow chart of another method for controlling linkage of multiple boilers provided in an embodiment of the present application is shown.

[0126] like Figure 4 As shown, the method for controlling multiple boilers in linkage may at least include the following steps:

[0127] Step 402: Collect monitoring data from at least two sensors, and generate a report based on the monitoring data from at least two sensors.

[0128] Specifically, step 402 may refer to step 102, which will not be described in detail here.

[0129] Step 404: Determine whether at least two boilers are in working order according to the report.

[0130] Specifically, step 404 may refer to step 104, which will not be described in detail here.

[0131] Step 406: When it is determined that at least two boilers are in operation, a fuzzy control operation is performed according to monitoring data of at least two sensors and a preset second threshold value to obtain a load ratio of the at least two boilers.

[0132] Specifically, when the controller determines that the at least two boilers are in working state, it can also directly perform automatic optimization fuzzy three-level closed-loop control operation based on the monitoring data collected by the at least two sensors and the preset second threshold value to obtain the ideal load ratio of the at least two boilers. The preset second threshold value can be determined according to the type of sensor, for example but not limited to when the sensor is a temperature sensor, the preset second threshold value can correspond to the preset load ratio of the steam temperature; when the sensor is a pressure sensor, the preset second threshold value can correspond to the preset load ratio of the steam pressure.

[0133] Step 408: Control at least two boilers based on the load ratio of the at least two boilers.

[0134] Specifically, after obtaining the ideal load ratio of the at least two boilers, the controller can directly adjust the current load ratio of each of the at least two boilers according to the ideal load ratio. It can be understood that in the embodiment of the present application, the number of the at least two boilers turned on can be the default number of boilers turned on, and the working state of each boiler can be controlled more quickly and effectively by controlling the load ratio of each boiler, so as to bring a more convenient control experience to the user.

[0135] See also Figure 5 , Figure 5 A flow chart of another method for controlling linkage of multiple boilers provided in an embodiment of the present application is shown.

[0136] like Figure 5 As shown, the method for controlling multiple boilers in linkage may at least include the following steps:

[0137] Step 502: Collect monitoring data from at least two sensors, and generate a report based on the monitoring data from at least two sensors.

[0138] Specifically, step 502 may refer to step 102, which will not be described in detail here.

[0139] Step 504: Determine whether at least two boilers are in working order according to the report.

[0140] Specifically, step 504 may refer to step 104, which will not be described in detail here.

[0141] Step 506: When it is determined that at least two boilers are not in the working state, control the at least two boilers according to the monitoring data of at least two sensors.

[0142] Specifically, step 506 may refer to step 106 and the multiple embodiments mentioned above, which will not be described in detail here.

[0143] Step 508: Determine the deviation between the monitoring data of at least two sensors and a preset target threshold.

[0144] Specifically, after the controller controls the at least two boilers according to the calculated ideal load ratio, or according to the preset number of units to be turned on, or according to the calculated ideal load ratio and the ideal number of units to be turned on, it can further calculate the deviation between the monitoring data of at least two sensors and the preset template threshold. It is understandable that the monitoring data of different sensors may correspond to different preset template thresholds. For example, when the type of sensor is a temperature sensor, the corresponding preset template threshold may be a preset temperature threshold, and the deviation may be the temperature difference between the current boiler steam temperature collected by the temperature sensor and the preset temperature threshold. When the type of sensor is a pressure sensor, the corresponding preset template threshold may be a preset pressure threshold, and the deviation may be the pressure difference between the current boiler steam temperature collected by the pressure sensor and the preset pressure threshold.

[0145] Step 510: When the deviation is within a first preset deviation interval, control the load ratio of any one of the at least two boilers to be a preset first load ratio.

[0146] Specifically, when the controller determines that the deviation is in the first preset deviation interval, the load ratio of any one of the at least two boilers can be controlled to be the preset first load ratio, wherein the control process may not change the number of boilers that are turned on, and only eliminate the influence of the control accuracy caused by the deviation by adjusting the load ratio of any one boiler. It can be understood that the first preset deviation interval here can be determined according to the type of sensor. For example, when the sensor is a temperature sensor, the first preset deviation interval can be between negative one degree and positive one degree, that is, the temperature difference between the current boiler steam temperature collected by the temperature sensor mentioned above and the preset temperature threshold is between negative one degree and positive one degree. It should also be noted that the first load ratio here can also be determined according to the deviation, for example but not limited to the first load ratio and the deviation satisfying a linear relationship in the embodiment of the present application.

[0147] Step 512: When the deviation is within the second preset deviation interval, control the load ratio of all boilers in the at least two boilers to be a preset second load ratio.

[0148] Specifically, when the controller determines that the deviation is in the second preset deviation interval, the load ratio of all boilers in the at least two boilers can be controlled to be the preset second load ratio, wherein the control process may not change the number of boilers turned on, and only adjust the load ratio of all boilers to eliminate the control accuracy caused by the deviation. It can be understood that, referring to the first preset deviation interval mentioned above, the second preset deviation interval can be determined according to the type of sensor, for example, when the sensor is a temperature sensor, the second preset deviation interval can be between negative two degrees and negative one degree and between positive one degree and positive two degrees, that is, the temperature difference between the current boiler steam temperature collected by the temperature sensor mentioned above and the preset temperature threshold is between negative two degrees and negative one degree or between positive one degree and positive two degrees. It should also be noted that the second load ratio here can also be determined according to the deviation, for example but not limited to the second load ratio and the deviation in the embodiment of the present application satisfying a linear relationship.

[0149] Step 514: When the deviation is within the third preset deviation interval, the number of at least two boilers that are turned on is controlled to be a preset number.

[0150] Specifically, when the controller determines that the deviation is in the third preset deviation interval, the number of boilers currently turned on of the at least two boilers can be controlled to be the preset number, wherein, due to the large deviation of the control process, it is necessary to quickly eliminate the influence of the control accuracy caused by the deviation by directly changing the number of boilers turned on. It can be understood that, referring to the first preset deviation interval and the second preset deviation interval mentioned above, the third preset deviation interval can be determined according to the type of sensor, for example, when the sensor is a temperature sensor, the third preset deviation interval can be between negative three degrees and negative two degrees and between positive two degrees and positive three degrees, that is, the temperature difference between the current boiler steam temperature collected by the temperature sensor mentioned above and the preset temperature threshold is between negative three degrees and negative two degrees or between positive two degrees and positive three degrees. It should also be noted that the preset number here can also be determined according to the deviation, for example but not limited to the preset number and the deviation satisfying a linear relationship in the embodiment of the present application.
