Description

Technical Field

[0001] The present invention relates to the technical field of constant temperature control of radars in high-cold areas, and in particular to a constant temperature method and system for trailer radars in high-cold areas based on multi-module unified temperature control. Background Art

[0002] Trailer radar is a trailer-type slope radar system integrated with slope radar and trailer system. It can adapt well to the monitoring environment in open-pit mine monitoring and can adjust the monitoring position at any time, avoiding the user's investment in monitoring room construction. Therefore, trailer radar can be used for detection operations in high-cold areas.

[0003] Although the trailer radar has good environmental adaptability in high-cold areas, it is still necessary to perform temperature control on the components of the trailer radar system in high-cold areas to keep the trailer radar system at a suitable working temperature for stable operation. At present, due to the different temperature control requirements of various modules of the trailer radar system, when meeting the temperature control requirements of all modules, the trailer radar system needs to be equipped with multiple heaters and coolers, which seriously increases the hardware burden of the trailer radar system. Moreover, it is difficult to reasonably share cold and hot resources in the modules of the trailer radar system with the same temperature control requirements when multiple heaters and coolers are arranged, which will inevitably cause waste of resources. For example, the radar host currently has a cooling demand, and the protection cabin also currently has a cooling demand. The corresponding cooler at the radar host is running for cooling control, and the corresponding cooler at the protection cabin is running for cooling control. The two coolers are independent of each other when running. At this time, two coolers are synchronously operated to perform a temperature control, resulting in a waste of resources.

DETAILED DESCRIPTION

[0017] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions 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 of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0018] like Figure 1 As shown, the present invention provides a method for maintaining constant temperature of trailer radar in high-cold areas based on multi-module unified temperature control, comprising the following steps: The temperature of the radar host, the control cabinet and the protective cabin are monitored by using sensor modules respectively arranged at the radar host, the control cabinet and the protective cabin in the trailer radar system in the high-cold region; A multi-module constant temperature independent scheduling model is constructed using a classifier to determine the scheduling mode of the heater module and the refrigerator module in the trailer radar system in the high-cold region according to the temperature of the radar host, the control cabinet and the protective cabin; Analyze the temperature dynamics of the radar host, the control cabinet, and the protective cabin according to the temperatures of the radar host, the control cabinet, and the protective cabin obtained by monitoring multiple historical time series; According to the temperature dynamic law, predict the duration that the temperature of the radar host, the control cabinet and the protective shelter exceeds the operating temperature threshold; The duration that the temperature of the radar host, control cabinet and protective cabin exceeds the operating temperature threshold is assigned to the constant temperature independent scheduling model as an output weight, and a multi-module constant temperature unified scheduling model is obtained for determining the scheduling mode of the heater module and the cooler module in the trailer radar system in high-cold areas according to the temperature of the radar host, control cabinet and protective cabin (after the current host temperature rises and recovers to the operating temperature range, the temperature is obtained again, the duration is calculated, and the constant temperature unified scheduling model is re-applied to adaptively control the priority; the advantage is that modules can be added and removed, and it is highly expandable).

[0019] The present invention aims at the constant temperature control demand of radar host, control cabinet and protective cabin, constructs a multi-module constant temperature independent scheduling model, determines the scheduling mode of heater module and refrigerator module in trailer radar system in high-cold areas according to the temperature of radar host, control cabinet and protective cabin, and realizes the targeted satisfaction of constant temperature control demand of each module in trailer radar system in high-cold areas. For example, the current temperature of radar host is -45 degrees Celsius, and the working threshold temperature range of radar host is -40 to +85 degrees Celsius. The current temperature of radar host is input into the constant temperature independent scheduling model A-Dis-tag=classifier(A-Tem) for radar host, and the heater module will be output. The scheduling tag for the heating operation of the block is the current temperature of the control cabinet, which is 50 degrees Celsius, and the operating threshold range of the control cabinet is -10 to 40 degrees Celsius. The current temperature of the control cabinet is input into the constant temperature independent scheduling model B-Dis-tag=classifier(B-Tem) for the control cabinet, and the scheduling tag for the cooling operation of the refrigerator module is output. The current temperature of the protection cabin is -5 degrees Celsius, and the operating threshold range of the protection cabin is -20 to 60 degrees Celsius. The current temperature of the protection cabin is input into the constant temperature independent scheduling model C-Dis-tag=classifier(C-Tem) for the protection cabin, and the scheduling tag for the heating operation of the heater module is output.

[0020] Furthermore, based on the multi-module constant temperature independent scheduling model, the present invention uses the duration that the temperatures of the radar host, control cabinet and protection cabin exceed the operating temperature threshold as a weight, and combines the multi-module constant temperature independent scheduling model into a multi-module constant temperature unified scheduling model, so that the radar host, control cabinet and protection cabin are converted from independent scheduling to unified scheduling, and the effect of multi-module independent temperature control can be achieved by setting up only one set of refrigerator and heater combination, and no resource waste will be caused.

[0021] For example, the current temperature of the radar host is -45 degrees Celsius. The current temperature of the radar host is input into the constant temperature independent scheduling model A-Dis-tag=classifier(A-Tem) for the radar host, and the scheduling tag for the heating operation of the heater module will be output. The current temperature of the control cabinet is 50 degrees Celsius. The current temperature of the control cabinet is input into the constant temperature independent scheduling model B-Dis-tag=classifier(B-Tem) for the control cabinet, and the scheduling tag for the cooling operation of the refrigerator module will be output. The current temperature of the protective cabin is -5 degrees Celsius. The current temperature of the protective cabin is input into the constant temperature independent scheduling model C-Dis-tag=classifier(C-Tem) for the protective cabin, and the scheduling tag for the heating operation of the heater module will be output.

[0022] As can be seen from the above, the radar host needs to perform constant temperature control for the heating operation of the heater module, the control cabinet needs to perform constant temperature control for the cooling operation of the refrigerator module, and the protective cabin needs to perform constant temperature control for the heating operation of the heater module. The real-time constant temperature control between these three has mutually exclusive temperature control requirements, and it is difficult to use a set of heater modules and refrigerator modules for unified control. Therefore, the prior art usually chooses to use three independent sets of heater modules and refrigerator modules for independent control, that is, one set is located at the radar host, one set is located at the control cabinet, and the other set is located at the protective cabin. However, the real-time constant temperature control between these three will have the same temperature control requirements. For example, the radar host and the protective cabin both need cooling control, and the corresponding two independent sets of heater modules and refrigerator modules are operated separately, which will cause waste. Therefore, the multi-module constant temperature independent scheduling model proposed in the present invention can be applied to the constant temperature control of three independent sets of heater modules and refrigerator modules.

[0023] In order to be able to apply to the constant temperature control of a set of heater modules and refrigerator modules, that is, to use a set of heater modules and refrigerator modules to transform the independent scheduling of the radar host, control cabinet and protective cabin into unified scheduling, the same effect of multi-module independent temperature control of three independent sets of heater modules and refrigerator modules can be obtained without causing waste of resources. The present invention adopts a constant temperature pre-control method to grasp the temperature trend and the temperature control time point in advance, and then combines the multi-module constant temperature independent scheduling model to realize the unified control of the radar host, control cabinet and protective cabin.

[0024] Among them, the duration of the temperature of the radar host, control cabinet and protective cabin exceeding the working temperature threshold can be used to measure the temperature control urgency of the radar host, control cabinet and protective cabin. The shorter the duration, the faster the temperature of the radar host, control cabinet and protective cabin exceeds the working temperature threshold, the faster the unsafe operation state is reached, and the more the temperature needs to be controlled to a constant temperature state. The higher the temperature control urgency, the duration of the temperature of the radar host, control cabinet and protective cabin exceeding the working temperature threshold is used as the weight, so that the temperature control priority between the radar host, control cabinet and protective cabin can be adaptively controlled, that is, the larger the weight of the output in the constant temperature independent scheduling model, the more important the output is, the greater the possibility of being selected by the classifier, and the final control result can be used. Therefore, when a set of refrigerators and heaters are used to uniformly schedule the temperature control of the radar host, control cabinet and protective cabin, the multi-module constant temperature unified scheduling model can realize the more priority constant temperature control of the modules with more urgent temperature control in the radar host, control cabinet and protective cabin.

[0025] Moreover, the duration that the temperature of the radar host, control cabinet and protective cabin exceeds the operating temperature threshold is a predicted value for the future, that is, when the temperature of the radar host, control cabinet and protective cabin is within the operating temperature threshold range, they are continuously monitored to understand their changing patterns. For example, the temperature of the radar host at 10:00 is 15 degrees Celsius, the temperature at 10:01 is 10 degrees Celsius, the temperature at 10:02 is 5 degrees Celsius, and the temperature at 10:03 is 0 degrees Celsius. By analogy, the time point when the operating temperature threshold is exceeded can be determined to be 10:11. Taking 10:00 as the current time, the duration that the radar host exceeds the operating temperature threshold is 11 minutes. It can be known that the radar host needs to perform constant temperature control for heater heating operation after 11 minutes. The pattern here is for illustration. In actual scenarios, it will not be such a simple dynamic pattern. The LSTM network will be used for summary learning. In this way, the temperature trend and temperature control time point can be known in advance at the current moment, and real-time constant temperature control can be started at the moment the operating temperature threshold is exceeded to ensure that the radar host can always be kept in a constant temperature state through temperature control.

[0026] In addition, assuming that the duration of the control cabinet exceeding the operating temperature threshold is 8 minutes, corresponding to the heater heating operation regulation, and the duration of the protective cabin exceeding the operating temperature threshold is 15 minutes, corresponding to the refrigerator cooling operation regulation, it means that the faster the control cabinet exceeds the operating temperature threshold, the faster it reaches an unsafe operating state, and the more it needs to control the temperature to a constant temperature state, and the higher the urgency of temperature control. Therefore, the normalized weight of the duration of the control cabinet exceeding the operating temperature threshold is 0.76, and the normalized weights of the duration of the protective cabin and the radar host exceeding the operating temperature threshold are 0.55 and 0.67, which corresponds to the shorter the duration, the more urgent the temperature control, and the greater the weight. Among them, (heater heating operation regulation, heating Heater heating operation control, refrigerator cooling operation control) are the three output results of the multi-module constant temperature independent scheduling model respectively. After weighting, we get (0.67*heater heating operation control, 0.76*heater heating operation control, 0.55*refrigerator cooling operation control). The maximum item of the probability distribution of (0.67*heater heating operation control, 0.76*heater heating operation control, 0.55*refrigerator cooling operation control) is output through the Softmax function to get the heater heating operation control as the output result of the multi-module constant temperature unified scheduling model, that is, the constant temperature control of the heater heating operation is performed 8 minutes later (i.e. 10:08), which is in line with the actual demand.

[0027] Moreover, the heater temperature rise operation regulation can share the heat resources with the radar host. Since the radar host also needs to perform a temperature rise operation, the temperature of the radar host rises, offsetting part of the temperature drop process of the radar host, and indirectly regulating the constant temperature of the radar host, that is, when the most urgent control cabinet is directly thermostatically regulated, the radar host is also thermostatically regulated indirectly, and the two processes share the heat resources of one regulation process. Then, due to the increase in temperature, the urgency of cooling the protective cabin will increase, and the refrigerator temperature reduction operation regulation process will be carried out. Therefore, unified regulation can be adaptively regulated according to the urgency of temperature control, meeting the actual needs while meeting the temperature control needs of each module, and can realize the sharing of hot and cold resources and maximize resource utilization.

[0028] Next, during the constant temperature control process of the heater heating operation at 10:08, the temperatures of the radar host, control cabinet and protective cabin are still obtained in real time. When the temperature of the control cabinet is found to be restored to the operating temperature threshold range, the temperature rise of the control cabinet is superimposed on the existing temperature change law to obtain a new temperature change law, and the duration of exceeding the operating temperature threshold is recalculated. The multi-module constant temperature unified scheduling model is reused to output the constant temperature control operation in the future sequence, so as to realize the pre-control of the constant temperature of the radar in the high-cold area, avoid the lagging control that causes the radar host, control cabinet and protective cabin to be exposed to unsafe temperatures, resulting in instrument damage or measurement errors.

[0029] For example, at 10:10, it is found that the temperature of the control cabinet has recovered to the operating temperature threshold range. The 10 degrees Celsius temperature increase of the control cabinet is superimposed on the existing temperature change law (A-Tem=LSTM(At)) to obtain a new temperature change law (A-Tem+10=LSTM(At)). At this time, the temperature of the radar host is -25 degrees Celsius and the temperature of the protective cabin is 40 degrees Celsius. At 10:10, the radar host, control cabinet and protective cabin are all within the operating temperature threshold range. Then, the temperatures of the radar host, control cabinet and protective cabin are monitored again at multiple time series after 10:10, the temperature change law of the new round of regulation is recalculated, the duration of the new round of exceeding the operating temperature threshold is recalculated, and the multi-module constant temperature unified scheduling model is reused to output a new round of constant temperature regulation operations in the future time series.

[0030] In summary, based on the duration of exceeding the operating temperature threshold predicted by the temperature change law, a multi-module constant temperature unified scheduling model is constructed in combination with a multi-module constant temperature independent scheduling model. The radar host, control cabinet and protective cabin are transformed from independent scheduling to unified scheduling, and the temperature control urgency is adaptively controlled to meet actual needs. The same effect of multi-module independent temperature control of three sets of independent heater modules and refrigerator modules can be obtained, and the sharing of cold and hot resources can be realized without wasting resources.

[0031] Aiming at the constant temperature control requirements of radar host, control cabinet and protective shelter, the present invention constructs a multi-module constant temperature independent scheduling model, realizes the scheduling mode of heater module and refrigerator module in trailer radar system in high-cold area according to the temperature of radar host, control cabinet and protective shelter, and realizes the targeted demand for constant temperature control of each module in trailer radar system in high-cold area, as follows: The construction method of the multi-module constant temperature independent scheduling model includes: Randomly obtain the temperatures of the radar host, the control cabinet, and the protective cabin at multiple time sequences; The temperature of the radar host, control cabinet and protective shelter at each time sequence is compared with the working temperature threshold of the radar host, control cabinet and protective shelter, wherein: The temperatures of the radar host, control cabinet and protective shelter that exceed the upper limit of the operating temperature threshold are assigned a scheduling tag for cooling operation of the refrigerator module; The temperatures of the radar host, the control cabinet, and the protective shelter that exceed the lower limit of the operating temperature threshold are assigned a scheduling tag for heating operation of the heater module; Assigning the temperatures of the radar host, the control cabinet, and the protective shelter that do not exceed the upper limit of the operating temperature threshold to a scheduling tag indicating that the cooler module is not operating and a scheduling tag indicating that the heater module is not operating; The temperatures of the radar host, the control cabinet and the protective cabin are used as the input of the classifier, and the dispatch labels corresponding to the temperatures of the radar host, the control cabinet and the protective cabin are used as the output of the classifier; The multi-module constant temperature independent scheduling model is constructed by training the mapping relationship between input and output by the classifier; The multi-module constant temperature independent scheduling model is: A-Dis-tag=classifier(A-Tem); B-Dis-tag=classifier(B-Tem); C-Dis-tag=classifier(C-Tem); In the formula, A-Dis-tag is the dispatch tag corresponding to the temperature of the radar host, A-Tem is the temperature of the radar host, B-Dis-tag is the dispatch tag corresponding to the temperature of the control cabinet, B-Tem is the temperature of the control cabinet, C-Dis-tag is the dispatch tag corresponding to the temperature of the protection cabin, C-Tem is the temperature of the protection cabin, and classifier is the classifier.

[0034] In order to be applicable to the constant temperature control of a set of heater modules and refrigerator modules, that is, using a set of heater modules and refrigerator modules to transform the radar host, control cabinet and protective cabin from independent scheduling to unified scheduling, the same effect of multi-module independent temperature control of three independent sets of heater modules and refrigerator modules can be obtained without causing waste of resources. The present invention adopts a constant temperature pre-control method to pre-master the temperature trend and the temperature control time point, and then combines the multi-module constant temperature independent scheduling model to realize the unified control of the radar host, control cabinet and protective cabin, as follows: The construction method of the multi-module constant temperature unified scheduling model includes: The time duration that the temperature of the radar host, the control cabinet and the protective cabin exceeds the working temperature threshold is normalized and assigned to the output of the multi-module constant temperature independent scheduling model as a weight to obtain the multi-module constant temperature unified scheduling model; The multi-module constant temperature unified scheduling model is: ABC-Dis-tag=Softmax( {1-(A-dt) / [(A-dt)+(B-dt)+(C-dt)]}*A-Dis-tag(A-tmin), {1-(B-dt) / [(A-dt)+(B-dt)+(C-dt)]}*B-Dis-tag(B-tmin), {1-(C-dt) / [(A-dt)+(B-dt)+(C-dt)]}*C-Dis-tag(C-tmin) ); Wherein, ABC-Dis-tag is the scheduling label output by the multi-module constant temperature unified scheduling model, Softmax is the Softmax function, A-dt is the duration that the temperature of the radar host exceeds the operating temperature threshold, B-dt is the duration that the temperature of the control cabinet exceeds the operating temperature threshold, C-dt is the duration that the temperature of the protection cabin exceeds the operating temperature threshold, A-tmin is the minimum sequential point when the temperature of the radar host exceeds the operating temperature threshold, B-tmin is the minimum sequential point when the temperature of the control cabinet exceeds the operating temperature threshold, and C-tmin is the minimum sequential point when the temperature of the protection cabin exceeds the operating temperature threshold; in, A-Dis-tag(A-tmin)=classifier(A-Tem(A-tmin)); B-Dis-tag(B-tmin)=classifier(B-Tem(B-tmin)); C-Dis-tag(C-tmin)=classifier(C-Tem(C-tmin)); Wherein, A-Dis-tag(A-tmin) is the dispatch tag corresponding to the temperature of the radar host at A-tmin, A-Tem(A-tmin) is the temperature of the radar host at A-tmin, B-Dis-tag(B-tmin) is the dispatch tag corresponding to the temperature of the control cabinet at B-tmin, B-Tem(B-tmin) is the temperature of the control cabinet at B-tmin, C-Dis-tag(C-tmin) is the dispatch tag corresponding to the temperature of the protective cabin at C-tmin, C-Tem(C-tmin) is the temperature of the protective cabin at C-tmin, and classifier is the classifier.

[0036] The method of using a multi-module constant temperature unified scheduling model to perform constant temperature control on the radar host, control cabinet and protective shelter includes: Acquire the temperature of the radar host, control cabinet and protective cabin at the current time sequence, and acquire the temperature of the radar host, control cabinet and protective cabin at multiple historical time sequences preceding the current time sequence; According to the temperatures of the radar host, the control cabinet and the protective cabin at multiple historical time series preceding the current time series, the temperature dynamic law at the current time series is analyzed; According to the temperature dynamics at the current time sequence, the duration for which the temperature of the radar host, control cabinet and protective shelter exceeds the operating temperature threshold is predicted; The duration that the temperature of the radar host, control cabinet and protective shelter exceeds the working temperature threshold and the temperature of the radar host, control cabinet and protective shelter at the current time sequence are input into the multi-module constant temperature unified scheduling model to obtain the scheduling label for constant temperature control of the radar host, control cabinet and protective shelter at the current time sequence; The operation of the heater module and the refrigerator module at the current timing is scheduled according to the scheduling tag.

[0037] Example: For example, the temperature of the radar host at 10:00 is 15 degrees Celsius, the temperature at 10:01 is 10 degrees Celsius, the temperature at 10:02 is 5 degrees Celsius, and the temperature at 10:03 is 0 degrees Celsius. By analogy, it can be determined that the time point when the operating temperature threshold is exceeded is 10:11. Taking 10:00 as the current time, the duration of the radar host exceeding the operating temperature threshold is 11 minutes. It can be determined that the radar host needs to perform constant temperature control of the heater heating operation after 11 minutes. The rule here is for illustration. In actual scenarios, it will not be such a simple dynamic rule, and the LSTM network will be used for summary learning.

[0038] In addition, assuming that the duration of the control cabinet exceeding the operating temperature threshold is 8 minutes, corresponding to the heater heating operation regulation, and the duration of the protective cabin exceeding the operating temperature threshold is 15 minutes, corresponding to the refrigerator cooling operation regulation, it means that the faster the control cabinet exceeds the operating temperature threshold, the faster it reaches an unsafe operating state, and the more it needs to control the temperature to a constant temperature state, and the higher the urgency of temperature control. Therefore, the normalized weight of the duration of the control cabinet exceeding the operating temperature threshold is 0.76, and the normalized weights of the duration of the protective cabin and the radar host exceeding the operating temperature threshold are 0.55 and 0.67, which corresponds to the shorter the duration, the more urgent the temperature control, and the greater the weight. Among them, (heater heating operation regulation, heating Heater heating operation control, refrigerator cooling operation control) are the three output results of the multi-module constant temperature independent scheduling model respectively. After weighting, we get (0.67*heater heating operation control, 0.76*heater heating operation control, 0.55*refrigerator cooling operation control). The maximum item of the probability distribution of (0.67*heater heating operation control, 0.76*heater heating operation control, 0.55*refrigerator cooling operation control) is output through the Softmax function to get the heater heating operation control as the output result of the multi-module constant temperature unified scheduling model, that is, the constant temperature control of the heater heating operation is performed 8 minutes later (i.e. 10:08), which is in line with the actual demand.

[0039] Next, during the constant temperature control process of the heater heating operation at 10:08, the temperatures of the radar host, control cabinet and protective cabin are still obtained in real time. At 10:10, it is found that the temperature of the control cabinet has returned to the operating temperature threshold range. The temperature increase of 10 degrees Celsius in the control cabinet is superimposed on the existing temperature change law (A-Tem=LSTM(At)) to obtain a new temperature change law (A-Tem+10=LSTM(At)). At this time, the temperature of the radar host is -25 degrees Celsius and the temperature of the protective cabin is 40 degrees Celsius. At 10:10, the radar host, control cabinet and protective cabin are all within the operating temperature threshold range. Then, the temperatures of the radar host, control cabinet and protective cabin are monitored again at multiple time series after 10:10, the temperature change law of the new round of control is recalculated, the duration of the new round of exceeding the operating temperature threshold is recalculated, and the multi-module constant temperature unified scheduling model is reused to output a new round of constant temperature control operations in the future time series. The loss functions of the multi-module constant temperature independent scheduling model and the multi-module constant temperature unified scheduling model are both cross entropy loss functions.
