[0002] During the manufacturing process, some large, critical equipment is of high value. Failures can impact product production cycles and incur high repair costs. Therefore, real-time monitoring of equipment operating temperatures, prompting timely warnings and early shutdowns for maintenance are essential. Traditional temperature warnings only issue alarms after an overtemperature event, potentially damaging the equipment. Furthermore, different devices experience varying temperature fluctuations in different environments. Traditional temperature warnings, which rely solely on device temperature and temperature thresholds, lack flexibility based on actual application scenarios. This can result in the equipment continuing to operate in an overheated environment between the time the temperature warning is issued and the time the equipment is adjusted, shortening its service life and reducing safety. Summary of the Invention

DETAILED DESCRIPTION

[0023] In order to enable those skilled in the art to better understand the present invention, the following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments in the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts should fall within the scope of protection of this application.

[0024] It should 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 sequential order. It should be understood that the data used in this way can be interchangeable where appropriate, so that the embodiments of the present application described herein can be implemented in a sequence other than those illustrated or described herein. In addition, the terms "including" and "having" and any of their variations are intended to cover non-exclusive inclusions, for example, a process, method, system, product or device comprising a series of steps or units is not necessarily limited to those steps or units clearly listed, but may include other steps or units that are not clearly listed or inherent to these processes, methods, products or devices.

[0025] The present invention provides an equipment operating temperature detection and early warning system, comprising:

[0026] Temperature acquisition module, used to determine the current temperature rise rate;

[0027] The control module predicts the temperature value after a set time based on the current temperature rise rate; if the temperature value after the set time is greater than or equal to the warning temperature, the warning module 13 is controlled to issue a temperature warning;

[0028] The warning temperature is determined according to the current temperature value and the critical temperature value.

[0029] The temperature acquisition module 11 can be a temperature sensor installed on the device, or a temperature sensor installed on an internal component of the device. Figure 1 As shown, in this embodiment, there is one temperature sensor, which is mounted on the housing of the device. In other embodiments, the number and specific location of the temperature sensors can be determined based on actual operating conditions. If there are multiple temperature sensors, the device temperature is the average of the temperatures detected by the multiple temperature sensors.

[0030] like Figure 2 As shown, the temperature acquisition module 11 is specifically used to acquire the operating temperature of the device and determine the temperature rise rate according to the operating temperature of the device. Figure 3 As shown, Figure 3 The middle dashed line represents the temperature rise rate of the device when the time is 10 minutes, and the straight line represents the highest operating temperature of the device in history. The temperature rise rate can be used to determine the speed of the device temperature change, such as Figure 3 In the example, curves 1 and 2 start at the same temperature. Ten minutes later, the temperature of curve 1 is significantly higher than that of curve 2, indicating that the temperature rise rate of curve 1 is greater than that of curve 2. If curve 2 were a normal temperature change curve, then the device corresponding to curve 1 would be at risk of temperature anomalies.

[0031] It should be noted that the equipment operation temperature detection and early warning system further includes a data storage module for storing the equipment temperature data collected by the temperature collection module 11 .

[0032] Specifically, the set time can be set or configured based on actual application conditions. Compared to the traditional method of judging whether the device is overheating based on real-time temperature, predicting the temperature value after a set time and judging the device status based on the temperature value at a future time can identify potential risks in advance, reserve sufficient time for intervention, and proactively prevent failures, thereby reducing the number of devices operating in an over-temperature state, extending the service life of the equipment, and improving safety.

[0033] The temperature value after the set time is calculated as follows:

[0034] T=Tm+K*t

[0035] Where T is the temperature value after the set time, Tm is the current temperature value, K is the current temperature rise rate, and t is the set time.

[0036] Specifically, the current temperature value is the device operating temperature collected by the temperature acquisition module 11 at the current time. The critical temperature value is used to compare with the current temperature value, and the warning temperature is determined based on the comparison result. This allows the likelihood of device overheating to be determined based on the current temperature, allowing different warning temperatures to be selected based on the likelihood of device overheating, thereby reducing the time the device operates in an overtemperature state. Compared to traditional fixed warning temperatures, the warning temperature determined based on the current temperature value and the critical temperature value is more flexible, making the warning mechanism more adaptable to the dynamic changes in the actual device operation scenario.

[0037] For example, the same motor experiences significant differences in heat dissipation conditions when operating in a hot summer workshop and a cold winter workshop, leading to significant discrepancies in average operating temperatures. Traditional early warning methods set fixed warning temperatures. In summer, this differential heat dissipation can trigger false alarms before the actual equipment temperature exceeds the limit, resulting in downtime and losses caused by over-protection. In winter, the low ambient temperature can mask abnormal equipment temperature increases, leading to missed warnings and increased maintenance costs.

[0038] Furthermore, the temperature acquisition module 11 is further configured to obtain temperature data of historical periods and determine a historical peak value of a current period node; and the control module 12 is further configured to determine a critical temperature value based on the historical peak value.

[0039] Specifically, the period can be set manually, and the period nodes change with the period. For example, the period can be set to 1 year, 1 month, 1 week, etc. If the period is 1 year, the period nodes can be set according to 4 quarters, 12 months, or 365 days.

[0040] As an example, if the period is 1 year and the period nodes are set according to the month, the temperature data for the historical period is as follows:

[0041]

[0042] The large time gaps between cycle nodes naturally lead to significant differences in equipment operating temperatures. In the Northern Hemisphere, the same motor operating in August and December will experience significant differences in ambient temperature and heat dissipation efficiency, leading to significant differences in average operating temperatures.

[0043] As shown in the table above, assuming the historical peak device temperature in August is 76.8°C and in December is 73.4°C, if the critical temperatures are the same, the warning temperature settings will be inaccurate, leading to frequent interruptions to device operation due to false warnings, or even losses caused by failure to intervene when the device exceeds the temperature.

[0044] The temperature critical value is determined based on the historical peak value of the current cycle node. When the interval between cycle nodes is long, the threshold value can be adjusted to adapt to the current environment, thereby improving the accuracy of the early warning and extending the service life of the equipment.

[0045] Furthermore, the control module 12 is also used to determine that the first preset temperature is the warning temperature if the current temperature value is less than the critical temperature value; if the current temperature value is greater than or equal to the critical temperature value, determine the second preset temperature as the warning temperature; the first preset temperature is less than the second preset temperature.

[0046] Specifically, the first and second preset temperatures are determined based on experimental data. If the first preset temperature is lower than the second preset temperature, that is, the corresponding warning temperature when the current temperature is low is lower than the corresponding warning temperature when the current temperature is high. This allows for flexible determination of the warning temperature based on the current temperature. By breaking the constraints of fixed thresholds, the warning method is more adaptable to changing environments and improves safety.

[0047] If the current temperature value is lower than the critical temperature value, it means that the current temperature of the equipment is not high and the operation time is not long. Figure 3 As shown in the figure, assuming the current operation time is 10 minutes, the equipment temperature rise curve is curve 1, which shows that the current temperature is relatively low. If the operation time is not long, it means that the equipment operating temperature may be in the climbing stage, and the temperature changes rapidly over time. Even in a short period of time, overheating may occur. Figure 3 ,Curve 1 exceeded the historical maximum temperature only 30 minutes before the operation.

[0048] At this time, because the current temperature is low, leaving ample room for temperature increases, a lower warning temperature is set to determine the temperature rise trend within the set time. If the temperature exceeds the warning temperature within the set time, it indicates a rapid temperature rise and a high probability of overheating within a short period of time. Preemptive intervention is required to prevent losses caused by prolonged operation of the equipment in an overheated state.

[0049] If the current temperature value is greater than the critical temperature value, it means that the current temperature of the equipment is high and the operation time is long. Figure 3 As shown in the figure, assuming the current operation time is 30 minutes, the equipment temperature rise curve is curve 2. It can be seen that the current temperature is high and close to the historical maximum temperature. At this time, the equipment temperature tends to be stable and the climbing speed is slow. The temperature climbing trend when the operation time is 30 minutes is significantly weaker than the temperature climbing trend when the operation time is 10 minutes. However, if no intervention is taken, overheating may occur as time goes by. Figure 3 , Curve 1 will also exceed the historical maximum temperature after 60 minutes of operation.

[0050] At this point, since the current temperature has already climbed to a high level, leaving little room for further increases, a higher warning temperature is set to determine the temperature rise trend within the set time. If the temperature exceeds the warning temperature within the set time, the device temperature will continue to rise, and the possibility of overheating increases over time. Preemptive intervention is required to prevent the device from operating in an excessively high temperature state.

[0051] Furthermore, the control module 12 is further configured to set a first coefficient; and determine the critical temperature value as the product of the historical peak value and the first coefficient.

[0052] Preferably, the first coefficient is less than 1.

[0053] Preferably, the first coefficient is 0.8.

[0054] As described above, the critical temperature value is compared with the current temperature value to determine the device's temperature trend and the rate of temperature rise. If the critical temperature value is greater than the historical maximum temperature, it indicates that the current temperature is high enough to determine the device's temperature trend. In this case, it is possible to determine that the device is overheating, without predicting the temperature at a preset time in the future.

[0055] Setting the critical temperature value lower than the historical peak value can provide sufficient time for temperature warning judgment and equipment intervention.

[0056] Furthermore, the control module 12 is further configured to determine a first preset temperature and a second preset temperature according to the historical peak value.

[0057] For example, consider a piece of production equipment with a set operating temperature alarm of 74°C under normal operating temperatures. However, in winter, when raw material temperatures are low, the actual temperature of the equipment often falls below 73°C due to material cooling. If the warning temperature is a set value or is unrelated to the current ambient temperature, the system will not issue a warning if the component temperature rises to 77°C due to poor lubrication, potentially missing the opportunity for maintenance. In summer, when ambient temperatures are high, the equipment may malfunction at 74°C due to poor heat dissipation, but no alarm will be issued because it has not reached the warning temperature, leading to overheating and damage.

[0058] Therefore, the warning temperature should also change with the ambient temperature to avoid problems such as frequent intervention in the operation of false warning equipment, or losses caused by the equipment being overheated but not intervened, thereby improving the accuracy of temperature warnings.

[0059] Furthermore, the control module 12 is also used to set a second coefficient to determine that the first preset temperature is the product of the historical peak value and the second coefficient; set a third coefficient to determine that the second preset temperature is the product of the historical peak value and the third coefficient, and the third coefficient is greater than the second coefficient.

[0060] Specifically, the second coefficient and the third coefficient can be set manually or according to experimental data.

[0061] Preferably, the second coefficient is 1 and the third coefficient is 1.05.

[0062] As an example, assuming that the historical peak value of the current cycle node is 74°C, the first preset temperature is 74°C and the second preset temperature is 77.7°C.

[0063] It should be noted that the warning temperature is lower than the operating temperature when the device overheats. This means that both the first and second preset temperatures are lower than the operating temperature when the device overheats. Therefore, when setting the second and third coefficients, it is important to consider the relationship between the operating temperature when the device overheats and its historical maximum temperature.

[0064] According to the above example, assuming that the operating temperature of the device when it overheats is 78° C., the second coefficient and the third coefficient are both less than 1.054.

[0065] Furthermore, it also includes a client, and the control module 12 is also used to obtain the associated client of the device; if the temperature value after the set time is greater than or equal to the warning temperature, a warning message is generated according to the temperature value after the set time; the control warning module 13 sends the warning message to the associated client.

[0066] It should be noted that the data storage module is also used to store the associated data between the device and the client.

[0067] Specifically, the warning information may include the device number and the location of the device to help users quickly find the device; the warning information may also include the temperature value after the set time and the operating temperature when the device is overheated.

[0068] Specifically, the associated client is used to receive warning information and notify the relevant person in charge of the equipment based on the warning information. The notification content can be to prompt the relevant person in charge of the equipment to check the equipment status on site or to prompt the relevant person in charge of the equipment to remotely control the equipment.

[0069] Furthermore, the warning information also includes a reference control operation for adjusting the operating temperature of the equipment; the control module 12 is also used to obtain historical control data of the current cycle node, and the historical control data includes historical temperature and historical control operations; based on the temperature value after the set time and the historical temperature, the historical control operation is determined to be a reference control operation.

[0070] Specifically, the reference control operations include increasing heat dissipation, turning on cooling, or reducing load.

[0071] Environmental factors and other factors at the current cycle node are similar to those at the current time, so the causes of the temperature increase are likely similar. The current historical control data can provide data support for the control module 12 to determine the reference adjustment operation. For example, if the difference between the temperature value after a set time and the historical temperature is less than a preset difference, it indicates that the device temperature after the set time is close to the historical temperature, and the historical control operation is likely to be applicable to the current situation. The preset difference is set based on experimental data.

[0072] Users can intervene in the equipment according to reference control operations, which can reduce user thinking time and reduce the risk of equipment operating in an over-temperature state.

[0073] Furthermore, the temperature acquisition module 11 is specifically configured to acquire a current temperature value at a current moment and historical temperature values ​​at previous moments; and determine a current temperature rise rate based on the current temperature value and the historical temperature values.

[0074] Specifically, the time interval between the current moment and the historical moment is relatively small and is set based on experimental data, thereby improving the accuracy of the temperature rise rate.

[0075] The current temperature rise rate is calculated as follows:

[0076] K=(T2–T1) / △t

[0077] Where K is the current temperature rise rate, T2 is the current temperature value, T1 is the historical temperature value, and △t is the time interval between the current moment and the historical moment.

[0078] As an example, assuming that T2 is 73.4° C., T1 is 71.8° C., and Δt is 10 minutes, the current temperature rise rate K is 0.16° C. / min.

[0079] like Figure 4 As shown, an embodiment of the present invention further provides a device operating temperature detection and early warning method, which is applied to the above-mentioned device operating temperature detection and early warning system, comprising:

[0080] Determine the current temperature rise rate; based on the current temperature rise rate, predict the temperature value after a set time; if the temperature value after the set time is greater than or equal to the warning temperature, control the warning module to perform a temperature warning; wherein the warning temperature is determined based on the current temperature value and the critical temperature value.

[0081] In another embodiment, Figure 2 As shown, the device operating temperature detection and early warning method also includes:

[0082] Obtain temperature data for historical periods and determine the historical peak value at the current period node;

[0083] The control module 12 is further configured to determine a critical temperature value based on the historical peak value;

[0084] If the current temperature value is less than the critical temperature value, determining the first preset temperature as the warning temperature;

[0085] If the current temperature value is greater than or equal to the critical temperature value, the second preset temperature is determined to be the warning temperature.

[0086] In summary, the present invention provides a device operating temperature detection and early warning system and method, which has the following beneficial effects compared with the prior art:

[0087] The warning temperature is determined by the current temperature value and the critical temperature value, which enables flexible determination of the warning temperature according to the application scenario, breaks the constraints of fixed thresholds, and makes the warning method more in line with the dynamic changes of the actual operation scenario of the equipment. The critical temperature value and the warning temperature are also determined by the temperature data of the historical cycle nodes, avoiding the problem of false alarms being triggered before the actual temperature of the equipment exceeds the limit or abnormal temperature rise of the equipment but missed maintenance opportunities due to omissions, thereby improving the accuracy of the warning; through the current temperature rise rate, the temperature value after the set time is predicted, and an alarm is triggered when the temperature value after the set time is greater than or equal to the warning temperature, actively preventing faults from occurring. At the same time, sufficient time is reserved for adjusting the temperature of the equipment, shortening the operating time of the equipment in the over-temperature state, extending the service life of the equipment, and improving safety.
