It is to be understood that the data so used is interchangeable under appropriate circumstances such that the embodiments of the invention described herein are capable of operation in sequences other than those illustrated or described herein. Furthermore, the terms "comprises," "comprising," and "having," and any variations thereof, are intended to cover a non-exclusive inclusion, such that a process, method, system, article, or apparatus that comprises a list of steps or elements is not necessarily limited to those steps or elements expressly listed, but may include other steps or elements not expressly listed or inherent to such process, method, article, or apparatus.
Fig. 1 is a flowchart of a method for controlling a heat dissipation system according to an embodiment of the present invention, where the method may be executed by the heat dissipation system and is applicable to new energy battery systems of ships, energy storage vehicles, commercial vehicles, and the like. The cooling system that this embodiment provided includes temperature control module and operating switch, and wherein operating switch and temperature control module mutual independence, and operating switch's priority is the highest, can be used to manual emergency control. The control method of the heat dissipation system comprises the following steps:
and S110, collecting temperature data in a preset area in real time.
And S120, when the operation switch is switched off, generating a temperature control signal according to the temperature data collected in the preset area in real time so as to determine whether to start the temperature control module.
Specifically, for new energy battery systems such as ships, energy storage and commercial vehicles, a lithium battery is generally used as a power battery to provide electric energy, and the lithium battery has the characteristics of high charging speed, high charging rate, high output power and the like. In practical application, the energy demand of ships or commercial vehicles on new energy batteries is large, the number of new energy batteries loaded on a single vehicle is large, a large amount of heat can be generated in the charging or discharging process of the new energy batteries, and at the moment, heat dissipation needs to be carried out through a heat dissipation system.
The operating switch is off, indicating that the manual emergency control of the heat dissipation system is off. At this time, the temperature data in the cabin can be collected in real time by arranging a collection module, such as a temperature sensor, in the cabin, wherein the temperature data can be the average temperature in the cabin or the temperature of a fixed point in the cabin. The cabin here refers to the cabin in which the new energy battery is located. After the acquisition module acquires the temperature data in the cabin, a temperature control signal is generated according to the acquired temperature data and is sent to the temperature control module, and the temperature control module determines whether to start according to the received temperature control signal.
And S130, if the temperature control module is started, before the heat dissipation system does not receive a shutdown signal, adjusting the operating parameters of the temperature control module based on the temperature data until the temperature data in the preset area meets the preset conditions.
Specifically, if the temperature control module confirms to start according to the received temperature control signal, before the heat dissipation system does not receive a system shutdown signal, the temperature control module adjusts the operating parameters of the temperature control module based on the temperature control signal and the temperature data acquired by the acquisition module to cool the environment in the cabin, and the temperature control module stops working until the temperature data in the preset area in the cabin meets the preset condition. The preset condition may be a preset temperature difference, that is, a difference between the adjusted temperature and the preset temperature; the preset area can be the whole cabin or a part of the area in the cabin. Illustratively, the preset temperature difference is 5 ℃, and when the temperature control module adjusts the operating parameters of the temperature control module to enable the difference between the temperature in the preset area and the preset temperature to be less than or equal to the preset temperature difference, the temperature control module is controlled to stop working.
In this embodiment, the shutdown signal is a signal for forcibly stopping the operation of the temperature control module, so as to ensure the safe and stable operation of the heat dissipation system, and the specific working process will be described in detail in the following embodiments.
According to the control method of the cooling system, when the operation switch is turned off, the temperature control signal is generated according to the temperature data collected in the preset area in real time, so that whether the temperature control module is started or not is determined; if the temperature control module is started, before the heat dissipation system does not receive a shutdown signal, adjusting the operating parameters of the temperature control module based on the temperature data until the temperature data in the preset area meets the preset conditions; wherein the preset condition at least comprises a preset temperature difference. Compared with the prior art, the technical scheme provided by the embodiment of the invention has the advantages that the area where the new energy battery is located is cooled in an automatic temperature control mode, and the operation parameters of the temperature control module can be automatically adjusted according to the temperature data in the cabin, so that the heat dissipation mode is not simplified any more, and the reduction of the energy consumption of a heat dissipation system is facilitated.
Optionally, the operating parameters of the temperature control module include at least rotational speed and power. In this embodiment, the temperature control module can be the fan, and through the rotational speed and the power of adjusting the fan, can adjust the size of the air output of fan, adjust the air output of fan in real time according to the different temperature data of gathering to reduce the consumption of fan, reduce whole cooling system's consumption.
Fig. 2 is a flowchart of another method for controlling a heat dissipation system according to an embodiment of the present invention, and referring to fig. 2, on the basis of the foregoing technical solution, the method for controlling a heat dissipation system according to the embodiment includes:
and S110, acquiring temperature data in a preset area in real time.
And S120, when the operation switch is switched off, generating a temperature control signal according to the temperature data collected in the preset area in real time so as to determine whether to start the temperature control module.
And S1301, if the temperature control module is started, determining the operating parameters of the temperature control module in the current state according to the temperature data.
And S1302, before the heat dissipation system does not receive the shutdown signal, adjusting the operating parameters of the temperature control module according to the temperature data.
And S1303, controlling the temperature control module to close when the temperature data in the preset area meets the preset conditions.
Specifically, after the temperature control module is determined to be started according to the temperature control signal, firstly, the operating parameters of the temperature control module in the current state are determined according to the acquired temperature data, namely, the rotating speed and the power required by the temperature control module in the current state are determined. And then determining whether the heat dissipation system receives a shutdown signal, if not, adjusting the operating parameters of the temperature control module according to the acquired temperature data, and outputting corresponding rotating speed and power by the temperature control module. When the collected temperature data in the preset area meets the preset conditions, the current temperature in the preset area meets the requirements, the temperature reduction operation is not required to be continued, the temperature control module can be controlled to be closed, and the heat dissipation system does not work, so that the power consumption of the heat dissipation system is reduced.
Fig. 3 is a flowchart of another control method of a heat dissipation system according to an embodiment of the present invention, and referring to fig. 3, on the basis of the foregoing technical solution, optionally after step S1302, the control method further includes:
and S13021, feeding back the adjusted operating parameters of the temperature control module to the heat dissipation system.
After the temperature control module adjusts the operating parameters of the temperature control module according to the acquired temperature data, the temperature control module outputs corresponding rotating speed and power according to the adjusted operating parameters, and feeds back the output operating parameters such as the rotating speed and the power to the heat dissipation system, so that the dynamic adjustment of the temperature control module can be realized.
In this embodiment, when the temperature data in the preset area does not satisfy the preset condition, the process returns to step S1301, and the operation parameters of the temperature control module are continuously adjusted until the temperature data in the preset area satisfies the preset condition.
In another embodiment of the present invention, the heat dissipation system further includes redundant control, fig. 4 is a flowchart of another control method of the heat dissipation system provided in the embodiment of the present invention, and with reference to fig. 4, on the basis of the foregoing technical solution, optionally, the control method of the heat dissipation system further includes:
and S110, acquiring temperature data in a preset area in real time.
S210, when the heat dissipation system detects that the temperature data in the preset area exceeds a preset threshold value, receives a first starting signal and does not receive a shutdown signal, controlling the temperature control module to work with the maximum operation parameter.
And S1303, controlling the temperature control module to be closed when the temperature data in the preset area meets the preset condition.
Specifically, after the temperature data in the preset area is collected, the heat dissipation system detects the collected temperature data. When the collected temperature data is detected to exceed a preset threshold value, the temperature control module reaches a hard-wire starting state, the heat dissipation system generates a first starting signal, and before the heat dissipation system does not receive a shutdown signal, the temperature control module works according to the first starting signal and the maximum operation parameters. And when the temperature data in the preset area is detected to meet the preset condition, controlling the temperature control module to be closed.
It should be noted that, in this embodiment, the acquisition module is directly connected to the temperature control module by a hard wire, and the automatic start of the temperature control module is implemented by using a redundancy design. Wherein the priority of the first starting signal is higher than that of the temperature control signal. When the detected temperature data exceeds the preset threshold value, the heat dissipation system automatically generates a first starting signal, so that the temperature control module operates at the maximum power. Here, the preset threshold may be set to a higher temperature threshold in order to ensure the stability of the operation of the heat dissipation system.
In this embodiment, the control method in step S210 is only used as an automatic start in an emergency state, and this design does not make a speed regulation setting in order to reduce the system cost.
In another embodiment of the present invention, the heat dissipation system further includes an emergency control, and on the basis of the foregoing technical solution, optionally, the control method of the heat dissipation system further includes:
and when the operation switch is closed according to the received second starting signal, controlling the temperature control module to work at the maximum operation parameter.
Wherein the priority of the second enable signal is higher than the priority of the first enable signal. In particular, the second enable signal is used to control the operational switch to close, which indicates that the manual emergency control of the heat dissipation system is on. By adding another group of hard wire signals, the situation that the temperature control module cannot be started or stopped normally when the heat dissipation system breaks down can be avoided.
According to the control method of the heat dissipation system, multiple heat dissipation control modes such as real-time automatic heat dissipation starting, forced heat dissipation starting and manual emergency heat dissipation starting are achieved by adding the multi-path redundant loop design, the operation safety of the heat dissipation system can be improved, and the phenomenon that the heat dissipation system cannot operate after one control mode breaks down is avoided.
Further, when the heat dissipation system receives a shutdown signal, the temperature control module is controlled to stop working, and fault warning information is sent out, so that related personnel can be informed to timely remove faults.
In this embodiment, the method for generating the temperature control signal according to the temperature data collected in the preset area in real time to determine whether to start the temperature control module may have different determination manners. Fig. 5 is a flowchart of another method for controlling a heat dissipation system according to an embodiment of the present invention, and referring to fig. 5, on the basis of the foregoing technical solutions, the method for controlling a heat dissipation system according to the embodiment includes:
s1101, collecting multipoint temperature data in a preset area in real time.
Specifically, collecting the multi-point temperature data in the preset area means that the temperature data of different position points are respectively collected by arranging a plurality of temperature collection modules, such as temperature sensors, at different positions in the preset area.
S1201, determining whether to start the temperature control module according to the relation between the average value of the multipoint temperature data and the preset temperature.
And S1202, if the average value of the multipoint temperature data is greater than or equal to the preset temperature, generating a first temperature control signal and controlling the temperature control module to start.
And S1203, if the average value of the multipoint temperature data is smaller than the preset temperature, generating a second temperature control signal and controlling the temperature control module to be closed.
Specifically, after multipoint temperature data in a preset area is acquired, an average value of the multipoint temperature data is obtained. For example, the acquired multipoint temperature data is transmitted to the control module, and the control module processes the multipoint temperature data to obtain an average value of the multipoint temperature data. And comparing the calculated average value of the multipoint temperature data with a preset temperature to determine whether to start the temperature control module, wherein the preset temperature can be stored in the control module. If the average value of the multipoint temperature data is larger than or equal to the preset temperature, a first temperature control signal is generated, the temperature control module is controlled to start, and the preset area in the cabin is cooled. And if the average value of the multipoint temperature data is less than the preset temperature, generating a second temperature control signal, controlling the temperature control module to be closed, and reducing the temperature of the preset area.

And S1213, if the single-point temperature data is less than the preset temperature, generating a second temperature control signal to control the temperature control module to close.
After single-point temperature data in a preset area are obtained, the obtained single-point temperature data are directly transmitted to the control module, the control module processes the single-point temperature data, the processed single-point temperature data are compared with preset temperature, and therefore whether the temperature control module is started or not is determined, wherein the preset temperature can be stored in the control module. If the single-point temperature data is greater than or equal to the preset temperature, a first temperature control signal is generated, the temperature control module is controlled to be started, and the preset area in the cabin is cooled. If the single-point temperature data is smaller than the preset temperature, a second temperature control signal is generated, the temperature control module is controlled to be closed, and the preset area does not need to be cooled.

If the temperature control module 40 determines to start according to the received temperature control signal, the operating parameters of the temperature control module 40 in the current state are determined according to the collected temperature data, that is, the power required to be output by the temperature control module 40 in the current state is determined. And then determining whether the heat radiation system receives a shutdown signal, if not, adjusting the operation parameters of the temperature control module 40 by the control module 20 according to the acquired temperature data, outputting corresponding rotating speed and power by the temperature control module 40, and feeding back the current actual power and rotating speed to the control module 20. When the acquisition module 10 acquires that the temperature data in the preset area meets the preset condition, it indicates that the current temperature in the preset area meets the requirement, and the temperature control module can be controlled to be closed at this time without continuing the cooling operation, so that the cooling system does not work, and the power consumption of the cooling system is reduced. If the temperature data in the preset area collected by the collection module 10 does not meet the preset conditions, the above steps are repeated to continuously adjust the operating parameters of the temperature control module 40 until the temperature data in the preset area meets the preset conditions.
When the heat dissipation system receives the shutdown signal, the first shutdown module 31 and the second shutdown module 32 are disconnected, the control circuit cannot be connected, and the control module 20 outputs alarm information to prompt a worker that the heat dissipation system has a fault.
Further, after the temperature data in the cabin is collected by the collection module 10 in real time, the temperature data collected by the collection module 10 is detected. When the collected temperature data is detected to exceed the preset threshold value, the temperature control module 40 reaches a hard-line starting state, the heat dissipation system generates a first starting signal to control the second shutdown module 32 to be closed (because the priority of the first starting signal is higher than that of the temperature control signal, the control module 20 cannot adjust the operation parameters of the temperature control module 40 at this time, here, even if the first shutdown module 31 is closed according to the first starting signal, the temperature control module 40 cannot adjust the operation parameters of itself), before the heat dissipation system does not receive the shutdown signal, the temperature control module 40 works with the maximum operation parameters according to the first starting signal, and therefore forced automatic starting of the heat dissipation system is achieved. And when the temperature data in the preset area is detected to meet the preset conditions, controlling the temperature control module 40 to close.
It should be noted that the first start signal here may be generated by another processing module in the heat dissipation system, or may be generated by the control module 20, which is not limited in this embodiment.
Further, when the heat dissipation system receives the second start signal, the operation switch 50 is turned on in response to the second start signal, and the temperature control module 40 directly operates at the maximum operating parameter until the operation switch 50 is turned off by receiving the turn-off signal, and the temperature control module 40 stops operating. The priority of the second start signal is higher than that of the first start signal, so that the temperature control module 40 can be prevented from being started or stopped normally when the heat dissipation system fails.
It should be noted that the temperature control module 40 provided in this embodiment may be a fan, a refrigerator, or other devices for dissipating heat. Wherein, one hard-wired circuit for directly controlling the temperature control module 40 by the operation switch 50 may be a manual emergency control circuit.
The embodiment of the invention provides a multi-path redundant loop design, can realize multiple heat dissipation control modes such as real-time automatic starting heat dissipation, forced starting heat dissipation, manual emergency starting heat dissipation and the like, can increase the operation safety of a heat dissipation system, and avoids the phenomenon that the heat dissipation system cannot operate after one control mode breaks down.
