[0018] Acquire a second temperature change rate of the target motor within a third time period;

[0019] If the second temperature change rate is greater than or equal to a second change rate threshold, the first shutdown shielding signal is generated.

[0020] In some embodiments of the present application, based on the aforementioned scheme, the value range of the first temperature threshold is 105-115 degrees Celsius, and the value range of the second temperature threshold is 125-135 degrees Celsius.

[0021] According to a second aspect of the present application, a strip steel production line control device is provided, wherein the strip steel production line includes a plurality of production line areas, each of the production line areas is provided with at least one motor, and the device includes:

[0031] The following will be combined with the drawings in the embodiments of the present application to clearly and completely describe the technical solutions in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

[0032] In addition, described feature, structure or characteristic can be combined in one or more embodiments in any suitable manner. In the following description, many specific details are provided to provide a full understanding of the embodiments of the present application. However, those skilled in the art will appreciate that the technical scheme of the present application can be put into practice without one or more of the specific details, or other methods, components, devices, steps, etc. can be adopted. In other cases, known methods, devices, realizations or operations are not shown or described in detail to avoid blurring the various aspects of the application.

[0033] The block diagrams shown in the accompanying drawings are merely functional entities and do not necessarily correspond to physically independent entities. That is, these functional entities may be implemented in software form, or in one or more hardware modules or integrated circuits, or in different networks and / or processor devices and / or microcontroller devices.

[0034] The flowcharts shown in the accompanying drawings are only exemplary and do not necessarily include all the contents and operations / steps, nor must they be executed in the order described. For example, some operations / steps can be decomposed, and some operations / steps can be combined or partially combined, so the actual execution order may change according to actual conditions.

[0035] It should also be noted that the terms "first", "second", etc. in the specification and claims of the present application and the above-mentioned drawings are used to distinguish similar objects, and are not necessarily used to describe a specific order or sequence. It should be understood that the objects used in this way can be interchanged where appropriate, so that the embodiments of the present application described herein can be implemented in an order other than those shown or described.

[0036] It should be noted that the strip steel production line usually has multiple production line areas, and each production line area is equipped with multiple motors, such as variable frequency motors. Each motor is responsible for transporting the strip steel of the production line and building the strip steel in each production line area. In order to detect the real-time temperature of the motor under working condition, a temperature sensor (such as a temperature measuring resistor) is usually built into the motor to detect the real-time temperature inside the motor. If the motor temperature is too high, it may cause motor burnout and other faults. In addition, if the motor (or fan) is a high-power device, the maintenance time after the motor burns out is longer, which affects the working efficiency of the entire strip steel production line.

[0037] In specific implementation, when the temperature sensor detects that the motor temperature reaches the fault threshold, for example, when it reaches 125 degrees Celsius, the motor controller will issue an over-temperature error, such as a local sound and light alarm and uploading the error information to the host computer. As a result, the host computer can send a control instruction to the motor controller to control the motor to stop, thereby avoiding safety hazards.

[0038] In the related art, when the motor overheats, the corresponding production line area will usually drop and stop quickly, that is, the production line area will stop. If the strip steel processed in the production line area is thin (for example, less than 0.5 mm), the strip steel furnace area needs to cool the strip steel, which further prolongs the downtime of the strip steel production line, for example, 2-3 hours, thus affecting the production efficiency of the strip steel.

[0039] It is understandable that under normal circumstances, the reasons for the motor temperature being too high include: the high temperature of the environment where the motor is located, the mismatch of the tension between the two heating sections in the furnace area causing the transmission roller to be overloaded (uneven force causing abnormal temperature rise), etc. The above situation can be identified as the motor itself having an overtemperature anomaly, and the temperature anomaly measured by the temperature sensor is a real temperature anomaly.

[0040] However, the inventors have found in their daily work that in some cases, the temperature sensor may also cause inaccurate measurement of the motor temperature, resulting in measurement failures such as overtemperature, temperature jumps, and temperature sensor disconnection. In the above cases, the temperature anomaly measured by the temperature sensor is a false temperature anomaly.

[0041] At present, whether it is a real temperature anomaly or a false temperature anomaly, it will trigger the shutdown of the strip production line area when the temperature reaches the over-temperature fault threshold, that is, there is a possibility of erroneous triggering of the strip production line area shutdown, thereby affecting the working efficiency of the strip production line.

[0042] On the basis of the above, according to the first aspect of the embodiment of the present application, a strip steel production line control method is provided, wherein the strip steel production line includes multiple production line areas, each of the production line areas is provided with at least one motor, and the method can be executed on a host computer in the strip steel production line, and the host computer can be communicated with the execution controller (i.e., the motor controller) of each motor to control the working state of the motor, wherein the method includes but is not limited to:

[0043] Step S1. Obtaining the real-time temperature of the target motor measured by the temperature sensor;

[0044] It can be understood that the temperature sensor can be a temperature measuring resistor, and the target motor can be any motor in the strip steel production line, which is not limited here.

[0045] Step S2. When the real-time temperature is greater than or equal to the first temperature threshold and less than the second temperature threshold, if a first shutdown shielding signal is obtained, then when the real-time temperature is greater than or equal to the second temperature threshold, the target production line area corresponding to the target motor is controlled to continue operating, the first temperature threshold is the over-temperature warning temperature of the target motor, the second temperature threshold is the over-temperature fault temperature of the target motor, and the first shutdown shielding signal is a signal obtained when there is a measurement fault in the temperature sensor.

[0046] In some embodiments of the present application, based on the above scheme, the value range of the first temperature threshold is 105-115 degrees Celsius, such as 105 degrees Celsius, 108 degrees Celsius, 110 degrees Celsius, 112 degrees Celsius, 115 degrees Celsius, etc.; the value range of the second temperature threshold is 125-135 degrees Celsius, such as 125 degrees Celsius, 128 degrees Celsius, 130 degrees Celsius, 132 degrees Celsius, 135 degrees Celsius, etc. The above examples are only used to represent the possible values ​​of the first temperature threshold and the second temperature threshold of the embodiments of the present application, and do not constitute a limitation on their specific values.

[0047] It is understandable that situations where the temperature sensor has a measurement failure include, but are not limited to, measurement failures such as the temperature sensor inaccurately measuring the motor temperature resulting in over-high temperature, a jump in the measured temperature, and a temperature sensor disconnection. When the temperature sensor has a measurement failure, the real-time temperature of the target motor received by the host computer is actually a false temperature. In this case, the first shutdown shielding signal can be used to avoid triggering the shutdown of the target production line area in the event of an over-temperature failure, thereby reducing problems that affect the normal operation of the target production line area, reducing shutdowns and production stoppages in the target production line area, and thus to a certain extent, being able to improve the working efficiency of the strip steel production line.

[0048] In some embodiments of the present application, based on the above solution, the first shutdown shielding signal is obtained as follows:

[0049] In response to a user's touch operation on a target touch button, the first shutdown shielding signal is obtained according to the touch operation.

[0050] It is understandable that when the real-time temperature of the target motor reaches the first temperature threshold (over-temperature warning temperature), the motor controller can issue a local sound and light alarm prompt, and the host computer can also issue text prompts, voice prompts, light prompts, etc. through the user interface, so that the user can check in time whether the target motor actually has an over-temperature problem according to the alarm prompt. For example, the real-time temperature sent by the temperature sensor to the host computer has reached 115 degrees, but the user finds through actual manual measurement that the actual temperature of the target motor is only 80 degrees. In this case, it can be considered that the target motor does not have an over-temperature problem, and the over-temperature value is caused by a measurement failure of the temperature sensor.

[0051] When the user has actually confirmed that the target motor does not have an over-temperature problem and that the actual over-temperature is caused by a measurement failure of the temperature sensor, the user can perform a touch operation through the target touch button set in the user interface of the host computer. As a result, the host computer responds to the user's touch operation on the target touch button, and obtains the first shutdown shielding signal according to the touch operation, so that the target production line area can be subsequently limited to shut down according to the first shutdown shielding signal, thereby avoiding the problem of false triggering of the production line shutdown.

[0052] In some embodiments, a touch button may be provided corresponding to each production line area of ​​the strip steel production line, whereby the user may limit the shutdown of the target production line area through the target touch button.

[0053] In some embodiments of the present application, based on the above solution, the first shutdown shielding signal is obtained as follows:

[0054] A second temperature change rate of the target motor within a third time period is acquired; if the second temperature change rate is greater than or equal to a second change rate threshold, the first shutdown shielding signal is generated.

[0055] It is understandable that the temperature change of the motor is usually continuous, for example, it rises continuously from 100 degrees Celsius to 110 degrees in 10 seconds. Then, if the target motor jumps from 100 degrees to 110 degrees, or from 100 degrees to 0 degrees in a very short time (for example, within 1 second), it is likely caused by a measurement failure of the temperature sensor. Based on this, the host computer can also automatically generate a first shutdown shielding signal according to the second temperature change rate of the target motor in the third time length, thereby reducing the manual workload of the user.

[0056] In some embodiments of the present application, based on the above solution, after acquiring the real-time temperature of the target motor measured by the temperature sensor, the method further includes:

[0057] When the real-time temperature is greater than or equal to the first temperature threshold and less than the second temperature threshold, if the first shutdown shielding signal is not obtained, the target production line area corresponding to the target motor is controlled to shut down after a first period of time starting from the first moment when the real-time temperature rises to the second temperature threshold.

[0058] It is understandable that when the real-time temperature reaches the over-temperature warning temperature but does not reach the over-temperature fault temperature, if the first shutdown shielding signal is not obtained, it means that the real-time temperature is the actual temperature of the target motor. Then when the real-time temperature reaches the over-temperature fault temperature, the target production line area is delayed to be triggered to shut down, that is, the target production line area is controlled to shut down after the first time period, wherein the first time period can be 5 minutes, 6 minutes, 8 minutes, 10 minutes, etc., thereby avoiding the target production line area being shut down immediately when the temperature of the target motor reaches the over-temperature fault temperature, resulting in the problem that the user cannot participate in subsequent decision-making when the target motor over-temperature faults.

[0059] It is understandable that the strip steel production line generally includes a heating furnace and a skin pass mill, and loopers are provided at the inlet and outlet of the heating furnace. From the first moment when the real-time temperature rises to the second temperature threshold, after a first time period, the looper tension controllers at the inlet and outlet can be controlled to cut off, and the skin pass mill can be controlled to trigger a quick opening.

[0060] In some embodiments of the present application, based on the above solution, after the first moment when the real-time temperature rises to the second temperature threshold, the method further includes:

[0061] If a second shutdown shielding signal is obtained within the first time period, then after the first time period, the target production line area corresponding to the target motor is controlled to continue operating, wherein the second shutdown shielding signal is a signal obtained when the first temperature change rate of the target motor within the second time period is less than or equal to the first change rate threshold, and the second time period is less than the first time period.

[0062] It is understandable that, in the process of the real-time temperature of the target motor rising to the second temperature threshold and entering the delayed shutdown, for example, in the process of entering the 10-minute countdown, if the user observes that within the second time length of the delay, for example, within 5 minutes of the delay, the temperature change rate of the target motor is small, for example, the temperature change rate within 5 minutes is 0.1%, indicating that the temperature change is very small and basically does not affect the subsequent strip processing. On this basis, the user can perform touch operation through the target touch button set in the user interface of the host computer, whereby the host computer responds to the user's touch operation on the target touch button, and obtains the second shutdown shielding signal according to the touch operation, so that the target production line area can be subsequently limited to shutdown according to the second shutdown shielding signal; or, the host computer can automatically compare the first temperature change rate within the second time length with the first change rate threshold, and if the first temperature change rate is less than or equal to the first change rate threshold, the second shutdown shielding signal is generated.

[0063] In some embodiments of the present application, based on the above solution, after the first moment when the real-time temperature rises to the second temperature threshold, the method further includes:

[0064] The remaining duration of the first duration is visually displayed so that the user can decide whether to perform the touch operation on the target touch button.

[0065] For example, a countdown is performed on the first time duration in the user interface of the host computer, such as a countdown of 10 minutes, so that the user can decide whether to perform a touch operation on the target touch button, thereby improving the user's work efficiency.

[0066] Based on the above disclosed content, the strip steel production line of the embodiment of the present application includes multiple production line areas, each production line area is provided with at least one motor, and the real-time temperature of the target motor measured by the temperature sensor is obtained; when the real-time temperature is greater than or equal to the first temperature threshold and less than the second temperature threshold, if the first shutdown shielding signal is obtained, then when the real-time temperature is greater than or equal to the second temperature threshold, the target production line area corresponding to the target motor is controlled to continue to operate, the first temperature threshold is the over-temperature warning temperature of the target motor, the second temperature threshold is the over-temperature fault temperature of the target motor, and the first shutdown shielding signal is a signal obtained when there is a measurement fault in the temperature sensor. Therefore, in the case of a measurement fault in the temperature sensor, that is, when there is a false over-temperature fault (not a real motor over-temperature fault), the first shutdown shielding signal is used to avoid triggering the shutdown of the target production line area when the temperature of the target motor reaches the over-temperature fault temperature, thereby affecting the normal operation of the target production line area, reducing the shutdown and production stoppage of the target production line area, and thus to a certain extent, the working efficiency of the strip steel production line can be improved.

[0070] The control unit 202 is used for controlling the target production line area corresponding to the target motor to continue operating when the real-time temperature is greater than or equal to the first temperature threshold and less than the second temperature threshold, if a first shutdown shielding signal is obtained. When the real-time temperature is greater than or equal to the second temperature threshold, the first temperature threshold is the over-temperature warning temperature of the target motor, the second temperature threshold is the over-temperature fault temperature of the target motor, and the first shutdown shielding signal is a signal obtained when there is a measurement fault in the temperature sensor.
