Embodiment one:
Referring to fig. 1 to 4, an embodiment of the present invention provides a method for monitoring and managing a motor system, where a plurality of micro-motors are disposed in the motor system, each micro-motor is configured with Peltier modules, and the Peltier modules are connected by a heat conducting material and are configured with heat dissipation modules arranged in parallel, where the heat dissipation modules are used to provide directional airflow.
The monitoring management method comprises the following steps:
S1, a motor system operates, power data of each micro-special motor is collected, a thermal imaging unit is used for monitoring heat distribution information of each micro-special motor in real time, and the power data and the heat distribution information of each micro-special motor obtained in real time are transmitted to a central control unit; the heat distribution information comprises temperature data and position information of the micro-special motor;
Firstly, starting a motor system, and starting to collect power data of each micro-special motor, so as to know the energy consumption level of each motor in a real-time working state. At the same time, the system is equipped with thermal imaging units that are capable of monitoring and capturing in real time the thermal profile information of each of the micro-motors, i.e. their surface temperature profile and heat accumulation. The temperature data collected by these thermal imaging units are sent to the central control unit together with the motor position information. Basic data required by the subsequent heat dissipation strategy formulation, such as the operation thermal efficiency and the thermal load estimation of each motor, are provided.
S2, the central control unit calculates the heat load of each micro-motor according to the power data and the temperature data through a preset power-temperature relation model, and determines the heat dissipation requirement of each micro-motor;
Focusing on the calculation of data processing and heat dissipation requirements, after the central control unit receives the power and temperature data from the motors of the micro-motors, it will perform a calculation analysis according to a preset power-temperature relationship model, which helps to determine the amount of heat load each motor generates in its operating state, and the central control unit uses these data to calculate the heat energy output of each motor accurately and determine their expected heat dissipation requirements accordingly, to evaluate the cooling requirements of each motor and quantify the heat dissipation resources required.
S3, according to the position information and the heat dissipation requirement of each micro-special motor, a heat dissipation strategy of a motor system is formulated;
The central control unit is provided with information for designing a heat dissipation strategy, and a comprehensive heat dissipation strategy is formulated according to the specific position information and heat dissipation requirement of each micro-special motor; the goal of the strategic design is to ensure that each motor achieves adequate cooling, and also to take into account the relative layout between the motors and the thermal effects that may affect each other. This strategy requires a fine-grained planning of the layout and mode of operation of the heat sink assembly to efficiently allocate heat sink resources.
S4, controlling the operation of the Peltier module at the corresponding position according to the heat dissipation strategy, and enabling the heat dissipation module to generate air flow with the corresponding wind direction to pass through the Peltier module and the heat conducting material so as to establish a heat dissipation path.
The actual operation and execution of the heat dissipation strategy formulated in the previous step, and the central control unit can now adjust and control the Peltier module and the corresponding position and working state of the heat dissipation module in the system according to the formulated heat dissipation strategy. According to the heat dissipation requirement, the heat dissipation module generates wind flow and directionally blows through the Peltier module and the heat conducting material, thereby forming an effective heat dissipation path. Preferably, in the process, the heat dissipation assembly is dynamically adjusted, so that heat dissipation optimization can be continuously performed according to real-time heat load information and motor working conditions, and the temperature management of the system is ensured to be optimized.
The working principle of the invention is as follows: when the motor system is started and starts to operate, the system automatically collects the power data of each micro-special motor, simultaneously monitors the temperature and position information of each motor in real time by utilizing the thermal imaging unit, and transmits the data to the central control unit; the central control unit calculates the heat load of each micro-special motor according to the data by using a preset power-temperature relation model to determine specific heat dissipation requirements, and then the central control unit establishes a comprehensive heat dissipation strategy of the whole system according to the accurate position information of each motor and the heat dissipation requirements thereof, and the heat dissipation strategy generates air flow with corresponding wind directions by regulating and controlling the operation state of the Peltier module at a specific position and the directional heat dissipation module, so that the air flow passes through the Peltier module and the heat conduction material to reach a heat dissipation path which is efficiently established, thereby meeting the heat dissipation requirements of each micro-special motor, ensuring the running stability of a motor system and prolonging the service life of the motor; compared with the management system in the prior art, the method has the advantages that the actual thermal state of each motor is accurately monitored and analyzed, the direct cooling of the Peltier module and the target airflow of the heat dissipation module are combined, the customized heat dissipation solution is provided by combining the thermal load of each micro-special motor, the accurate and effective thermal management function is realized, and the effective operation of the motor system is ensured.
In this embodiment, it is specifically described that step S2 specifically includes:
s21, carrying out initial screening of outlier rejection on the received power data and temperature data through a central control unit, and confirming data integrity;
The central control unit performs a preliminary processing of the received power data and temperature data, including checking the integrity of the data to ensure that the information used in the subsequent calculations is comprehensive. In this link, the system identifies and rejects outliers that may occur due to sensor measurement errors or during data transmission, such as read jumps or out-of-range values, to ensure the accuracy of the data set.
S22, calculating heat loss by combining temperature data through a preset power-temperature relation model, and calculating total power consumption by combining power data, so as to calculate the real-time heat energy conversion efficiency of each micro-special motor by using the heat loss/total power consumption;
Processing temperature data and power data by using a preset power-temperature relation model, and firstly calculating possible loss heat energy of the micro-special motor in a working state through the temperature data, namely, part of heat energy which is not converted into useful mechanical energy and is emitted to the environment; the power data is then used to calculate the total power consumption of the motor, i.e. the total power input to the micro-machine. The comparison result of the two items of data is used for calculating the real-time heat energy conversion efficiency of each micro-special motor, and the efficiency index reflects the energy efficiency of motor operation.
S23, according to the characteristic parameters of the micro-special motor, the central control unit selects the heat transfer coefficient matched with the characteristic parameters of the micro-special motor from the heat transfer coefficient parameter library. To accurately estimate the heat dissipation characteristics thereof; the characteristic parameters are factory marking data of the micro-special motor and are set according to the material properties and the structural characteristics of the micro-special motor.
Selecting a proper heat transfer coefficient from a maintained heat transfer coefficient parameter library according to the characteristic parameters of the micro-special motor; wherein, the heat transfer coefficients correspond to the heat conduction capacity of different materials under specific conditions, and are key parameters for calculating a heat dissipation path and designing a heat dissipation system; the heat loss of the motor in the running process is accurately estimated by correctly selecting the heat transfer coefficient matched with the motor characteristics, and the heat dissipation capacity and the heat dissipation mode required by the micro-special motor under the current working environment and temperature conditions are determined.
In this embodiment, it is further explained that step S23 includes, after:
S24, applying a real-time heat balance analysis algorithm, and calculating the heat load of each micro-motor in the current working state by combining the heat transfer coefficient and the air heat conductivity coefficient of the environmental condition;
a real-time thermal balance analysis algorithm is applied to further process the determined heat transfer coefficients. The algorithm combines the material characteristics of the micro-special motor, the heat conductivity coefficient of the ambient air and the current working state to evaluate the heat load generated by the corresponding micro-special motor. The real-time thermal balance analysis algorithm takes into account the energy exchange between each motor and the surrounding environment, including various heat transfer modes such as heat generation, conduction, convection, radiation, and the like. From this calculation, it is possible to know the heat generated by each micro-motor under specific operating conditions, and the heat that needs to be dissipated to maintain the motor in the normal temperature range, i.e. the heat load.
S25, comparing the calculated heat load with a preset heat dissipation efficiency standard table to obtain the cooling intensity level of each micro-special motor so as to determine the heat dissipation requirement.
The specific heat dissipation requirement of the micro-special motor is determined according to the known heat load, and the heat load data is compared with a preset heat dissipation efficiency standard table, wherein the standard table possibly comprises heat dissipation parameters with different intensity levels, such as required heat dissipation area, heat dissipation rate, acceptable temperature range and the like. Each motor is assigned a cooling intensity level that matches its heat dissipation requirements to ensure that the appropriate amount of cooling resources are provided to each motor to avoid performance degradation or energy waste due to insufficient or excessive cooling. Therefore, the heat dissipation requirement of each micro-special motor is determined, and a basis is provided for the follow-up execution of a heat dissipation strategy.
In this embodiment, it is specifically described that step S3 specifically includes:
S31, initializing a heat dissipation management mode of a motor system, constructing a motor layout map in the motor system according to the position information of each micro-special motor, and marking a heat interaction area in the motor layout map;
The central control unit utilizes the position information of each micro-special motor to construct a motor layout map, and the map ensures the accurate knowledge of the spatial position and the mutual distance of each motor in the system. On the basis, the heat interaction areas on the motor layout map are marked, positions where heat is possibly affected or transferred mutually are identified, and a visual reference is provided for a subsequent heat dissipation strategy. The scientificity and pertinence of the heat dissipation strategy are ensured, and uneven heat dissipation caused by neglecting heat influence among motors is avoided.
S32, integrating the heat dissipation requirement of each micro-special motor and the range of the heat interaction area, and making a multi-factor heat dissipation adjustment model by the central control unit;
The central control unit starts to design a heat dissipation management strategy according to the constructed motor layout map and the heat interaction relation between the motors, integrates the heat dissipation requirement of each micro-special motor and the data of the heat interaction area, and sets a multi-factor heat dissipation adjustment model. This model not only takes into account the independent heat dissipation requirements of a single motor, but also covers the complex dynamics of heat transfer between motors. In this way, the central control unit can calculate the most suitable heat dissipation strategy according to the specific conditions of each motor in the system, and ensure that each motor can be properly cooled.
S33, a directional heat dissipation strategy is planned through the multi-factor heat dissipation adjustment model, and the operation power of the Peltier module corresponding to each micro-special motor and the strength and the direction of air flow generated by the heat dissipation module are determined.
And (3) making a heat dissipation plan by the multi-factor heat dissipation regulation model constructed in the previous step, and determining that the Peltier module corresponding to each micro-special motor is required to operate at corresponding power and the strength and the direction of air flow required to be generated by the corresponding heat dissipation module by the central control unit according to the output of the model. This ensures that each micro-machine is able to achieve adequate and properly directed air flow cooling, and that the Peltier module provides the necessary cooling power for it, thereby accurately regulating the distribution and flow of heat within the system. This directed heat dissipation strategy aims to efficiently utilize heat dissipation resources and reduce the overall energy consumption of the system.
As a preferred aspect of the present embodiment, the Peltier module includes:
the semiconductor coupling assembly comprises a plurality of thermocouples, wherein the thermocouples are formed by pairing P-type and N-type semiconductor materials; the semiconductor coupling assembly is provided with a cold end and a hot end, and the cold end is attached to the surface of the micro-special motor;
the ceramic plate base is arranged outside the semiconductor coupling assembly in a surrounding mode;
and the radiator is arranged between the hot end of the semiconductor coupling component and the connecting heat conducting material.
In this embodiment, it is further explained that step S4 includes, after:
S5, an energy management mechanism is established, corresponding heat loads are calculated according to the operating power of the Peltier module and the heat dissipation module, the heat dissipation strategy is optimized according to the heat loads, and the optimized heat dissipation strategy is operated.
In this embodiment, it is specifically described that step S5 specifically includes:
s51, monitoring the running power of each Peltier module and the heat dissipation module in real time through an energy monitoring unit, calculating the energy consumption data of the Peltier module and the heat dissipation module through the obtained running power, and recording the energy consumption data in real time;
The system captures the running power of each Peltier module and each heat dissipation module in real time by using the energy monitoring unit, and provides accurate energy consumption data for energy management of the whole motor system. In order to continuously monitor and record these data, the energy monitoring unit must be highly reliable and accurate. Through the real-time recorded power and energy consumption data, the system can evaluate the efficiency and power consumption of each heat dissipation component, so that the central control unit can further understand the current heat dissipation operation state, and support is provided for subsequent heat dissipation strategy adjustment.
S52, updating the heat dissipation requirement of each micro-special motor according to the calculated energy consumption data, calculating the heat load proportion of the corresponding micro-special motor, and generating a heat load distribution diagram;
The central control unit will use the monitored operating power and energy consumption data to calculate the heat load of each of the motors, which calculation can help identify the relationship between the heat actually generated by each of the motors and the amount of cooling they have from the heat dissipation module, i.e., the heat load ratio. With the information, a comprehensive thermal load distribution diagram can be constructed, and the heat generation and transmission conditions of each motor are shown in detail. Such a graph can intuitively reveal the thermal profile in the system, providing an important reference for the following optimization of the heat dissipation strategy.
S53, analyzing the thermal load distribution diagram, and identifying a heat dissipation abnormal region so as to locally adjust a heat dissipation strategy; the heat dissipation abnormal region includes a heat dissipation insufficient region and a heat dissipation excessive region.
By optimizing the existing heat dissipation strategy. Based on the analysis of the thermal load profile, the central control unit can identify areas of abnormal heat dissipation, including areas of insufficient or excessive heat dissipation. If the heat dissipation in a certain area is insufficient, the motor may overheat, and excessive heat dissipation may mean that the heat dissipation strength is wasted. Therefore, the central control unit needs to make fine adjustments to the heat dissipation strategy, such as changing the cooling intensity of the relevant Peltier module, optimizing the wind speed and direction of the heat dissipation fan. By implementing such local adjustment, it is possible to ensure a good balance between the heat radiation effect and the motor operation demand and to improve the overall heat radiation efficiency while preventing unnecessary energy consumption.
In this embodiment, it is further explained that step S53 includes, after:
S54, introducing a cost function, taking an optimal balance index between heat dissipation energy consumption and heat dissipation effect as a target, and calculating an optimal heat dissipation configuration through an optimization algorithm; the cost function takes heat dissipation efficiency, energy consumption and long-term stability into account.
The relationship between heat dissipation energy consumption and heat dissipation effect is balanced by introducing a cost function, which is a mathematical tool designed to measure the cost and benefit of different heat dissipation schemes, with the ultimate goal of finding an optimal balance index to minimize energy consumption while maximizing heat dissipation efficiency. By applying an optimization algorithm, such as a gradient descent algorithm, the system can iteratively search for and determine the most appropriate Peltier module operating parameters and heat sink module configuration. This approach ensures that the system not only pursues efficient heat dissipation, but also focuses on energy conservation and cost effectiveness, helping the motor system to maintain an optimal state continuously during long-term operation.
S55, applying a closed-loop feedback control system, and continuously and iteratively optimizing a heat dissipation strategy according to the periodically updated energy consumption data and the corresponding optimal heat dissipation configuration; ensuring that the system remains in an optimal operating state even in the event of changes in the external environment or workload.
The self-adaptability and the accuracy of the heat dissipation strategy are further improved by adopting a closed-loop feedback control mechanism, and the closed-loop feedback control system continuously carries out iterative optimization on the heat dissipation strategy of the identified abnormal region according to the periodically updated energy consumption data obtained from the energy monitoring unit and the optimal heat dissipation configuration obtained through calculation. One significant advantage of closed loop systems is their ability to dynamically respond to environmental and system changes, ensuring that the heat dissipation management can adapt to changes in various modes of operation and environmental conditions, thereby automatically adjusting the heat dissipation parameters on a real-time basis.
And S56, after the optimization of the heat dissipation strategy is completed each time, the central control unit controls the operation of the Peltier module at the corresponding position through the new heat dissipation strategy, and the heat dissipation module generates air flow in the corresponding wind direction so as to optimize the heat dissipation path.
The optimized heat dissipation strategy is applied to the implementation link, and after each iteration optimization, the central control unit updates the operation parameters of the Peltier module and the heat dissipation module and controls the Peltier module and the heat dissipation module to generate the airflow of the wind direction and the wind force adjusted according to the latest strategy. Thus, not only is more accurate heat dissipation provided for each micro-motor, but also the heat dissipation path of the whole motor system is optimized to improve the cooling efficiency. This step ensures consistency and reliability of heat dissipation management and helps to extend the life of the motor assembly and the stable operation of the overall system.
