Technical field

The present application relates to, but is not limited to, the field of communications technologies, and in particular, to a method and an apparatus for controlling a data transmission device.

Background technique

With the development of mobile devices, the size of data transmission devices is getting smaller and smaller, and thinner. At the same time, due to the development of mobile communication technologies, the transmission rate is getting higher and higher, and the technical problem brought about by this is that Under medium-intensity signal or weak-intensity signal, if the high-speed downloading of data continues, the temperature of the data transmission device will continue to rise for the following reasons: because the signal coverage of the base station may not be completely consistent, there will be many weak signal zones. For example, the signal strength is -110db, but these regional devices can be networked and transmitted data normally. Therefore, in order to ensure the normal transmission of data, the radio frequency of the device needs to increase the transmission power. If the data transmission continues, the temperature of the device will slowly decrease.

Detailed

It is understood that the embodiments described herein are merely illustrative of the application and are not intended to limit the application.

The application provides a method for controlling a data transmission device. Referring to Figure 1, the present application A flowchart of a first embodiment of a method of controlling a data transmission device.

In this embodiment, the method for controlling the data transmission device includes:

Step S10: acquiring, in the process of data transmission by the data transmission device, acquiring a temperature of the data transmission device;

In step S20, when the acquired temperature is greater than the first temperature threshold, the transmission rate or the transmission power of the data transmission device is reduced according to the restriction manner corresponding to the acquired temperature, where the transmission rate includes an uplink transmission rate and a downlink transmission. rate.

The data transmission device in the embodiment of the present invention may be various devices for data transmission. When the data transmission device is in use, a SIM (Subscriber Identification Module) card may be installed, and the data transmission device communicates with the base station to connect. To the cellular network, the data transmission of the cellular network is performed, and the WIFI module can also be set in the data transmission device, and the wireless communication can be established with other mobile terminals based on the WIFI network, and the mobile terminal can be a WIFI function, such as a mobile phone or a tablet computer. Mobile terminal. That is to say, the data transmission device can only perform data transmission under the cellular network, and can also serve as a WIFI hotspot, and open a WIFI hotspot function while establishing a cellular network connection, and the user establishes a WIFI connection with the device through the mobile terminal to implement data. transmission. In addition to the WIFI hotspot, the mobile terminal can also access the data transmission device by using a USB (Universal Serial Bus) data line and an RJ45 network cable to realize data transmission, wherein the RJ45 is an information socket connector in the wiring system. One, "RJ45" is a common name for the standard eight-bit modular interface.

The data transmission device is provided with a temperature detecting device, such as a temperature sensor, or a thermistor is provided, and the temperature change is detected by the thermistor, and the temperature detected by the temperature detecting device is obtained in a timed or real-time manner during data transmission of the device. For example, the temperature is obtained once every 2 to 5 seconds, and it is judged whether the temperature is greater than the first temperature threshold. If yes, the current device temperature is high, and the temperature needs to be reduced, and the restriction method to be adopted is The size of the obtained temperature is related.

As an implementation manner, as shown in FIG. 2, step S20 may include:

In step S21, when the acquired temperature is greater than the first temperature threshold and less than the second temperature threshold, the transmission rate of the data transmission device is decreased according to the limited manner corresponding to the acquired temperature, wherein the first temperature threshold is less than Describe a second temperature threshold;

In step S22, when the acquired temperature is greater than the second temperature threshold, the transmission power of the data transmission device is reduced according to a limitation manner corresponding to the acquired temperature.

The device obtains the temperature in real time or periodically. When the detected temperature is greater than the first temperature threshold, the transmission rate is limited. If the detected temperature is greater than the second temperature threshold, the current signal strength may be very weak, or the device itself The ambient temperature is relatively high, so that after the processing of reducing the transmission rate, the temperature of the device cannot be completely limited, and the temperature rises above the second temperature threshold, thereby reducing the transmission power of the device. Because when the signal is weak, in order to ensure the normal transmission of data, the device will automatically increase the transmission power, which will lead to a rapid increase in temperature. At this time, the device temperature can be lowered by reducing the transmission power, in order to avoid lowering the device. When the power is transmitted, the phenomenon of network disconnection or current interruption occurs. According to the performance of the device chip and the actual use environment, the maximum adjustable transmit power value is determined, for example, gradually decreasing, and each time is reduced by 3 to 6 db.

As an exemplary embodiment, step S21 may include the following refinement steps:

When the acquired temperature is greater than or equal to the third temperature threshold and less than the second temperature threshold, the WIFI network transmission rate of the data transmission device is decreased.

When the obtained temperature is greater than the first temperature threshold and less than the third temperature threshold, the transmission rate of the data transmission of the device based on the cellular network is limited, and the transmission rate is reduced, and the transmission rate includes an uplink transmission rate and a downlink transmission rate. That is, the first temperature threshold is a temperature upper limit value in the cellular network, and when the detected temperature is greater than the first temperature threshold and less than the third temperature threshold, the speed limit processing is required, which may be adopted in this embodiment. The speed limit tool limits the uplink transmission rate and the downlink transmission rate, for example, the TC speed limit tool in the Linux system. By reducing the transmission rate of the cellular network, the temperature of the device will be reduced. In the related art, the BSR (Buffer Status Report) parameter is generally used for speed reduction, but the speed reduction method can only adjust the uplink transmission rate, and the rate adjustment is limited by many other factors. The control method of the data transmission device proposed by the embodiment can adjust both the uplink rate and the downlink rate in the foregoing manner, and is not limited by other factors, and can provide a good experience for the user.

Those skilled in the art can understand that the first temperature threshold, the second temperature threshold, and the third temperature The degree threshold and one or more temperature thresholds that will be referred to below may be set by the user as needed.

As an exemplary embodiment, after reducing the transmission rate of the data transmission device based on the cellular network, the status of the data transmission device may be marked as a rate limiting state. Since the temperature does not immediately fall below the first temperature threshold immediately after the rate is lowered, it takes a certain amount of time. Therefore, after the transmission rate is lowered, the device is marked as a speed limit state, since the temperature is still in real time. Detecting, when it is detected that the temperature is greater than the first temperature threshold and less than the third temperature threshold, determining whether the data transmission device is in a speed limit state; if the speed limit state is at this time, the acquisition distance is lower based on the last time The time interval of the transmission rate of the network; when the acquired time interval is greater than the preset time interval, reducing the transmission rate of the data transmission device based on the cellular network.

That is to say, for the rate adjustment, a certain sleep time is set, and the temperature acquired during the sleep time is not used as a basis for reducing the transmission rate in the cellular network, and when the time interval reaches the preset time interval, if the detection is performed, If the temperature reached is still greater than the first temperature threshold and less than the third temperature threshold, then the transmission rate continues to decrease.

Regarding the manner of reducing the transmission rate, a reduced preset ratio, for example, 50%, may be set in advance, and each time the transmission rate is lowered, the transmission rate is reduced to 50% of the current transmission rate. The preset time interval may be set according to the specific performance of the device and the user needs. For example, the preset time interval may be 20 to 60 seconds. In an exemplary embodiment, the preset time interval may be 30 seconds.

As an exemplary implementation, if the device transmits data according to the cellular network and also has data transmission between the WIFI network and the mobile terminal, the device may be caused by long-term high-speed data transmission based on the WIFI network. The temperature rises. Therefore, after the speed limit on the cellular network, the temperature of the device may increase. When the temperature is detected to be greater than the third temperature threshold, the transmission rate of the WIFI network of the data transmission device is lowered. For example, By controlling the number of WIFI data sent in unit time, the rate of WIFI data is slowed down. In actual use, the probability of occurrence of this situation is low, and the transmission rate of the WIFI network can be reduced to a lower value, so that The temperature of the device is lowered.

The control method of the data transmission device in the embodiment, in the data transmission process of the data transmission device, acquires the temperature of the device, and limits the transmission rate of the data transmission device according to the limited manner corresponding to the acquired temperature, so as to implement According to the temperature of the device acquired at a time, the data transmission rate of the device is dynamically adjusted to achieve the purpose of adjusting the temperature, and avoiding the continuous data. The temperature rise of the device is too high, which effectively controls the temperature of the data transmission device, improves the stability of the device, and avoids scalding the user due to excessive temperature to improve the safety of the device.

A second embodiment of the control method of the data transmission device of the present application is proposed based on the first embodiment. In this embodiment, after the step S10, the control method of the data transmission device may further include:

When the ambient temperature of the device itself is relatively high, if the signal is weaker at this time, and the user is performing continuous data transmission, the temperature may suddenly rise rapidly. In this embodiment, in order to further improve the overall device The performance is: when the detected temperature is greater than the fourth temperature threshold, disconnecting the cellular network connection of the data transmission device, and further, if the network is disconnected for a period of time, the temperature is still higher than the fourth temperature threshold, in order to ensure the device and the user For security, the device is controlled to be turned off, and the shutdown prompt message is output before the shutdown.

A third embodiment of the control method of the data transmission device of the present application is proposed based on the above-described first embodiment or second embodiment. In this embodiment, after the step S10, the control method of the data transmission device may further include:

On the premise of controlling the temperature, in order to ensure the normal transmission speed of the data, when the detected temperature is less than the fifth temperature threshold and the current device is marked as the speed limit state, the temperature has decreased after the speed limit, wherein the fifth temperature The threshold is smaller than the first temperature threshold. At this time, the cellular network of the data transmission device is subjected to speed up processing to ensure that the data has a normal transmission rate.

Wherein, when the transmission rate of the device based on the cellular network is increased, the transmission rate may be gradually increased according to a plurality of preset gear positions, for example, a five-speed rate is preset, wherein an uplink rate of the previous gear transmission rate is higher than The uplink rate of the next gear, the downlink rate of the previous gear rate is higher than the downlink rate of the next gear. When the transmission rate is increased, it is first determined that the current rate is in the first gear position, and then the transmission rate is raised to the previous gear position of the current gear position.

Among them, after each speed increase, the status of the device is marked as the speed increase state, and sleep is performed, and the temperature acquired during the sleep time is not used as the basis for the increase of the transmission rate under the cellular network, when the distance is increased from the previous transmission rate. When the high time interval is greater than the preset time interval, if the detected temperature is still less than the fifth temperature threshold, the transmission rate continues to increase. In this embodiment, the preset time interval may be greater than the preset time interval during the speed reduction processing, because the “fast fall and slow rise” manner can effectively reduce the round-trip fluctuation of the rate and bring a good user experience.

The control method of the data transmission device proposed in this embodiment can not only avoid the excessive temperature of the device, but also achieve the balance between the temperature and the rate, and further improve the overall performance of the device.

A fourth embodiment of the control method of the data transmission device of the present application is proposed based on any of the above embodiments. In this embodiment, after the step S20, the control method of the data transmission device may further include:

Since the transmission rate or the transmission power of the device is limited, the temperature thereof will gradually decrease. When the acquired temperature is lower than the sixth temperature threshold, the temperature of the device has been lowered to a low level. In this case, in order to ensure the data of the device. It can be transmitted at a reasonable rate, or it can work at a reasonable transmission power, and the transmission rate and the transmission power are released. Further, if the network is currently disconnected, the network is restarted. If the device has been shut down, the user needs to manually Open.

The application also proposes a control device for a data transmission device.

Referring to FIG. 3, it is a schematic diagram of functional modules of a first embodiment of a control device for a data transmission device of the present application.

In this embodiment, the control device of the data transmission device includes:

The obtaining module 10 is configured to acquire a temperature of the data transmission device during data transmission by the data transmission device;

The control module 20 is configured to reduce the transmission rate or the transmission power of the data transmission device according to the limitation manner of the acquired temperature when the acquired temperature is greater than the first temperature threshold, where The transmission rate includes an uplink transmission rate and a downlink transmission rate.

The data transmission device in the embodiment of the present invention may be various devices for data transmission. When the data transmission device is in use, a SIM card may be installed, and the data transmission device communicates with the base station to connect to the cellular network to perform data of the cellular network. The WIFI module can also be set up in the data transmission device, and the wireless communication can be established with other mobile terminals based on the WIFI network. The mobile terminal can be a mobile terminal or a tablet computer with a WIFI function. That is to say, the data transmission device can only perform data transmission under the cellular network, and can also serve as a WIFI hotspot, and open a WIFI hotspot function while establishing a cellular network connection, and the user establishes a WIFI connection with the device through the mobile terminal to implement data. transmission. It can be understood by those skilled in the art that the control device of the data transmission device in the embodiment of the present invention may be the data transmission device itself, implemented by a function module built in the device, or may be independent of the device and may be established with the device. Connected controls. In addition to the WIFI hotspot, the mobile terminal can also access the data transmission device by using a USB (Universal Serial Bus) data line and an RJ45 network cable to realize data transmission, wherein the RJ45 is an information socket connector in the wiring system. One, "RJ45" is a common name for the standard eight-bit modular interface.

The data transmission device is provided with a temperature detecting device, such as a temperature sensor, or a thermistor, and the temperature change is detected by the thermistor. During the data transmission process of the device, the acquiring module 10 acquires the temperature detecting device for detection in a timed or real time. The temperature to be obtained, for example, is obtained once every 2 to 5 seconds, and it is judged whether the temperature is greater than the first temperature threshold. If yes, the current device temperature is high, and the temperature is required to be processed, and the control module 20 is used. The way to limit it depends on the size of the temperature obtained.

As an embodiment, the control module 20 may be further configured to: when the acquired temperature is greater than the first temperature threshold and less than the second temperature threshold, reduce the transmission rate of the data transmission device according to the limited manner corresponding to the acquired temperature. Wherein the first temperature threshold is less than the second temperature threshold;

The device obtains the temperature in real time. When the temperature is greater than the first temperature threshold, the transmission rate is limited. If the detected temperature is greater than the second temperature threshold, the current signal strength may be It is often weak, or the ambient temperature of the device itself is relatively high, so that after the processing of reducing the transmission rate, the temperature of the device cannot be completely limited. At this time, the control module 20 reduces the transmission power of the device. Because when the signal is weak, in order to ensure the normal transmission of data, the device will automatically increase the transmission power, which will cause the temperature to rise rapidly. At this time, the device temperature can be lowered by reducing the transmission power, in order to avoid reducing the device emission. When the power is off, the phenomenon of disconnection or disconnection occurs. According to the performance of the device chip and the actual use environment, the maximum adjustable transmit power value is determined, for example, gradually decreasing, and each time is reduced by 3 to 6 db.

As an exemplary embodiment, referring to FIG. 4, the control module 20 may include:

The cellular network control sub-module 21 is configured to reduce the transmission rate of the data transmission device based on the cellular network when the acquired temperature is greater than the first temperature threshold and less than the third temperature threshold, wherein the third temperature threshold Greater than the first temperature threshold and less than the second temperature threshold;

The WIFI network control sub-module 22 is configured to reduce the WIFI network transmission rate of the data transmission device when the acquired temperature is greater than or equal to the third temperature threshold and less than the second temperature threshold.

When the obtained temperature is greater than the first temperature threshold and less than the third temperature threshold, the cellular network control sub-module 21 limits the transmission rate of the data transmission of the device based on the cellular network, and reduces the transmission rate, where the transmission rate includes the uplink transmission rate. And downlink transmission rate. That is, the first temperature threshold is a temperature upper limit value in the cellular network, and when the detected temperature is greater than the first temperature threshold and less than the third temperature threshold, speed limiting processing is required. In this embodiment, the cellular network The control sub-module 21 can limit the uplink transmission rate and the downlink transmission rate by using a suitable rate limiting tool, for example, a TC speed limit tool in a Linux system. By reducing the transmission rate of the cellular network, the temperature of the device will be reduced. In the related art, the BSR (Buffer Status Report) parameter is generally used to reduce the speed, but the speed reduction mode can only adjust the uplink transmission rate, and the rate adjustment is limited by many other factors. The control device of the data transmission device proposed in the embodiment can adjust both the uplink rate and the downlink rate in the above manner, and is not limited by other factors, and can provide a good experience for the user.

Those skilled in the art will appreciate that the first temperature threshold, the second temperature threshold, the third temperature threshold, and one or more temperature thresholds that will be referred to below may be set by the user as desired.

As an exemplary embodiment, the control device of the data transmission device may further include:

a tagging module configured to reduce the data transmission device based on a cellular network at the control module 20 After the transmission rate of the network, the status of the data transmission device is marked as a speed limit state;

The cellular network control sub-module 21 can include:

After reducing the transmission rate of the data transmission device based on the cellular network, the tagging module marks the status of the data transmission device as a rate limiting state. Since the temperature does not immediately fall below the first temperature threshold immediately after the rate is lowered, it takes a certain amount of time. Therefore, after reducing the transmission rate, the marking module marks the device as a speed limit state, due to the temperature still In the real-time detection, when it is detected that the temperature is greater than the first temperature threshold and is less than the third temperature threshold, the determining unit determines whether the data transmission device is in a speed limit state; if the speed limit state is obtained at this time, the acquiring unit acquires The time interval of the last reduction of the transmission rate based on the cellular network; when the acquired time interval is greater than the preset time interval, the control unit reduces the transmission rate of the data transmission device based on the cellular network.

That is to say, for the rate adjustment, a certain sleep time is set, and the temperature acquired during the sleep time is not used as a basis for reducing the transmission rate in the cellular network, and if the time interval reaches the preset time interval, if the time interval is obtained, The temperature acquired by the module 10 is still greater than the first temperature threshold and less than the third temperature threshold, and the control unit continues to decrease the transmission rate.

Regarding the manner of reducing the transmission rate, a reduced preset ratio, for example, 50%, may be set in advance, and each time the transmission rate is lowered, the transmission rate is reduced to 50% of the current transmission rate. The preset time interval may be set according to the specific performance of the device and the user's needs. For example, the preset time interval is 20 to 60 seconds. In an exemplary embodiment, the preset time interval may be 30 seconds.

As an exemplary implementation, if the device transmits data according to the cellular network and also has data transmission between the WIFI network and the mobile terminal, the device may be caused by long-term high-speed data transmission based on the WIFI network. The temperature rises, therefore, after the limit on the cellular network After the speed, the temperature of the device may also increase. When the detected temperature is greater than the third temperature threshold, the WIFI network control sub-module 22 reduces the transmission rate of the WIFI network, for example, by controlling the number of packets sent by the WIFI data in a unit time. To slow down the rate of WIFI data, in the actual use process, the probability of occurrence of this situation is relatively low, and the transmission rate of the WIFI network can be reduced to a lower value to lower the temperature of the device.

The control device of the data transmission device provided in this embodiment acquires the temperature of the device during the data transmission process of the data transmission device, and limits the transmission rate of the data transmission device according to the limitation manner of the acquired temperature, so as to implement According to the temperature of the device acquired at a time, the data transmission rate of the device is dynamically adjusted to achieve the purpose of adjusting the temperature, thereby avoiding the temperature rise of the device due to continuous downloading of the data, and effectively controlling the temperature of the data transmission device. Improve the stability of the equipment while avoiding scalding the user due to excessive temperature to improve the safety of the equipment.

A second embodiment of the control device of the data transmission device of the present application is proposed based on the first embodiment. In this embodiment, the control module 20 may be further configured to: when the acquired temperature is greater than the fourth temperature threshold, disconnect the cellular network connection of the data transmission device, where the fourth temperature threshold is greater than the second Temperature threshold.

When the ambient temperature of the device itself is relatively high, if the signal is weaker at this time, and the user is performing continuous data transmission, the temperature may suddenly rise rapidly. Therefore, in this embodiment, in order to further improve the device. The overall performance, when the detected temperature is greater than the fourth temperature threshold, the control module 20 disconnects the cellular network connection of the data transmission device, and further, if the network is disconnected for a period of time, the temperature is still higher than the fourth temperature threshold, To ensure the security of the device and the user, the device is controlled to be shut down, and the shutdown prompt message is output before the shutdown.

A third embodiment of the control device of the data transmission device of the present application is proposed based on the above-described first embodiment or second embodiment. In this embodiment, the control device of the data transmission device may further include:

a marking module, configured to mark a state of the data transmission device as a speed limit state after the control module 20 reduces the transmission rate of the data transmission device based on the cellular network;

The control module 20 is further configured to: when the acquired temperature is less than the fifth temperature threshold, and the data transmission device is currently in the speed limit state, the cellular network of the data transmission device is subjected to speed up processing, wherein the The fifth temperature threshold is less than the first temperature threshold.

After the control module 20 reduces the transmission rate of the data transmission device based on the cellular network, the marking module marks the state of the data transmission device as a speed limit state.
