Detailed Description
it should be understood that the specific embodiments described herein are merely illustrative of the invention and are not intended to limit the invention.
The invention provides a control method of data transmission equipment. Referring to fig. 1, a flowchart of a first embodiment of a method for controlling a data transmission device according to the present invention is shown.
in this embodiment, the method for controlling the data transmission device includes:
step S10, acquiring the temperature of the data transmission equipment in the process of data transmission by the data transmission equipment;
And step S20, when the obtained temperature is greater than the first temperature threshold, reducing the transmission rate of the data transmission equipment according to a limiting mode corresponding to the obtained temperature, wherein the transmission rate comprises an uplink transmission rate and a downlink transmission rate.
The data transmission equipment in the embodiment of the invention can be various equipment for data transmission, when the data transmission equipment is used, an SIM card can be installed, the data transmission equipment is communicated with the base station to be connected to the cellular network for data transmission of the cellular network, a WIFI module can be further arranged in the data transmission equipment, wireless communication can be established with other mobile terminals based on the WIFI network, and the mobile terminals can be mobile terminals with WIFI functions such as mobile phones and tablet computers. That is to say, this data transmission equipment can only carry out data transmission under the cellular network, can also regard as the WIFI focus, opens WIFI focus function when establishing cellular network connection, and the user establishes the WIFI connection with this equipment through mobile terminal, realizes the transmission of data. Besides the WIFI hotspot, the mobile terminal may access the data transmission device by using a USB (Universal Serial Bus) data line, an RJ45 network line, and the like, to realize data transmission, where RJ45 is a kind of information socket connector in the wiring system, and "RJ 45" is a common name of a standard eight-bit modular interface.
The data transmission equipment is provided with a temperature detection device, such as a temperature sensor, or a thermistor, the temperature change is detected through the thermistor, the temperature detected by the temperature detection device is acquired at regular time or in real time in the data transmission process of the equipment, for example, the temperature is acquired every 2-5 seconds, whether the temperature is greater than a first temperature threshold value is judged, if yes, the current equipment temperature is higher, the temperature needs to be reduced, and the limit mode to be adopted is related to the acquired temperature.
As an embodiment, step S20 includes:
step S21, when the obtained temperature is greater than a first temperature threshold and less than a second temperature threshold, reducing the transmission rate of the data transmission equipment according to a limiting mode corresponding to the obtained temperature, wherein the first temperature threshold is less than the second temperature threshold;
And step S22, when the obtained temperature is greater than the second temperature threshold, reducing the transmission power of the data transmission device in a limiting manner corresponding to the obtained temperature.
The device can acquire the temperature in real time or at regular time, when the detected temperature is greater than the first temperature threshold, the transmission rate can be limited, if the detected temperature is greater than the second temperature threshold, the temperature of the device still cannot be completely limited after the processing of reducing the transmission rate due to the fact that the current signal strength is very weak or the ambient temperature of the device is higher, the temperature is increased to be higher than the second temperature threshold, and the transmission power of the device is reduced at the moment. Because the device automatically increases the transmission power to ensure normal transmission of data when the signal is weak, which causes a rapid temperature rise, the temperature of the device can be reduced by reducing the transmission power, and in order to avoid network interruption or current interruption when the transmission power of the device is reduced, the maximum adjustable transmission power value is determined according to the performance of the chip of the device and the actual use environment, for example, the maximum adjustable transmission power value is gradually reduced by 3-6db each time.
further, as an embodiment, referring to fig. 2, the step S21 may include the following detailed steps:
When the obtained temperature is greater than the first temperature threshold and less than a third temperature threshold, reducing the transmission rate of the data transmission device based on a cellular network, wherein the third temperature threshold is greater than the first temperature threshold and less than the second temperature threshold;
and when the acquired temperature is greater than or equal to a third temperature threshold and less than a second temperature threshold, reducing the transmission rate of the data transmission equipment based on the WIFI network.
And when the acquired temperature is greater than the first temperature threshold and less than a third temperature threshold, limiting the transmission rate of the data transmission of the device based on the cellular network, and reducing the transmission rate, wherein the transmission rate comprises an uplink transmission rate and a downlink transmission rate. That is to say, the first temperature threshold is the upper temperature limit value in the cellular network, and when the detected temperature is greater than the first temperature threshold and smaller than the third temperature threshold, speed limit processing needs to be performed. By reducing the transmission rate of the cellular network, the temperature of the device may be reduced. In the prior art, the speed reduction is generally performed by adjusting a BSR (Buffer Status Report) parameter, but this speed reduction method can only adjust the uplink transmission rate, and the rate adjustment is limited by a plurality of other factors.
it will be appreciated by those skilled in the art that the first temperature threshold, the second temperature threshold, the third temperature threshold, and the various temperature thresholds to be referred to below may be set by the user as desired.
Further, as an embodiment, after the transmission rate of the data transmission device based on the cellular network is reduced, the state of the data transmission device is marked as a speed limit state. Since the temperature is not immediately reduced to be lower than the first temperature threshold value after the rate is just reduced, but a certain time is needed, after the transmission rate is reduced, the equipment is marked to be in a speed-limiting state, and since the temperature is still detected in real time, when the temperature is detected to be higher than the first temperature threshold value and lower than a third temperature threshold value again, whether the data transmission equipment is in the speed-limiting state or not is judged; if the speed is limited, acquiring a time interval from the last reduction of the transmission rate based on the cellular network; and when the acquired time interval is greater than a preset time interval, reducing the transmission rate of the data transmission equipment based on the cellular network.
That is to say, for rate adjustment, a certain sleep time is set, the temperature obtained in this sleep time is not used as a basis for reducing the transmission rate in the cellular network, and when the time interval reaches a preset time interval, if the detected temperature is still greater than the first temperature threshold and less than the third temperature threshold, the transmission rate continues to be reduced.
as for the manner of reducing the transmission rate, a preset proportion of reduction, for example, 50%, may be set in advance, and each time the transmission rate is reduced, the transmission rate is reduced to 50% of the current transmission rate. The preset time interval may be set according to specific performance of the device and user needs, and optionally, the preset time interval is 20 to 60 seconds, and in an embodiment, the preset time interval is 30 seconds.
Optionally, as an implementation manner, if the device transmits data based on the cellular network and simultaneously transmits data based on the WIFI network and the mobile terminal, the temperature of the device may increase due to long-time high-rate data mutual transmission based on the WIFI network, and therefore, after the speed limit on the cellular network is performed, the temperature of the device may also increase, and when the detected temperature is greater than the third temperature threshold, the transmission rate based on the WIFI network is reduced, for example, the rate of the WIFI data may be reduced by controlling the number of packets sent by the WIFI data in a unit time.
In the data transmission process of the data transmission device, the temperature of the device is acquired, and the transmission rate of the data transmission device is limited according to the limiting mode corresponding to the acquired temperature, so that the data transmission rate of the device is dynamically adjusted according to the temperature of the device acquired at regular time, the purpose of adjusting the temperature is achieved, the phenomenon that the temperature of the device rises too high due to continuous downloading of data is avoided, the effective control on the temperature of the data transmission device is realized, the stability of the device is improved, meanwhile, the phenomenon that a user is scalded due to too high temperature is avoided, and the safety of the device is improved.
A second embodiment of the control method of the data transmission device of the present invention is proposed based on the first embodiment. In this embodiment, after step S10, the method of controlling a data transmission apparatus further includes:
And when the acquired temperature is greater than a fourth temperature threshold, disconnecting the cellular network of the data transmission equipment, wherein the fourth temperature threshold is greater than the second temperature threshold.
In this embodiment, in order to further improve the overall performance of the device, when the detected temperature is greater than the fourth temperature threshold, the cellular network connection of the data transmission device is disconnected, further, after the network is disconnected for a period of time, the temperature is still greater than the fourth temperature threshold, and in order to ensure the safety of the device and the user, the device is controlled to be powered off, and a power-off prompt message is output before the device is powered off.
A third embodiment of the control method of the data transmission device of the present invention is proposed based on the first embodiment or the second embodiment described above. In this embodiment, after step S10, the method of controlling a data transmission apparatus further includes:
and when the acquired temperature is smaller than a fifth temperature threshold value and the data transmission equipment is in a speed limiting state currently, carrying out speed increasing processing on the cellular network of the data transmission equipment, wherein the fifth temperature threshold value is smaller than the first temperature threshold value.
on the premise of controlling the temperature, in order to ensure the normal transmission speed of the data, when the temperature is detected to be less than a fifth temperature threshold and the current device is marked as a speed-limited state, it is indicated that the temperature is reduced after speed limitation, wherein the fifth temperature threshold is less than the first temperature threshold, and at this time, the cellular network of the data transmission device is subjected to speed-up processing to ensure that the data has the normal transmission speed.
specifically, when the cellular network based transmission rate of the device is increased, the transmission rate may be gradually increased according to a plurality of preset gears, for example, a five-gear rate is preset, where an uplink rate of a last gear transmission rate is higher than an uplink rate of a next gear, and a downlink rate of the last gear transmission rate is higher than a downlink rate of the next gear. When increasing the transmission rate, it is first determined that the current rate is in the several th gear, and then the transmission rate is increased to the previous gear of the current gear.
Further, after each speed increase, the state of the device is marked as the speed increase state, and the device sleeps, the temperature acquired in the sleeping time is not used as a basis for increasing the transmission rate in the cellular network, and when the time interval from the last time of increasing the transmission rate is greater than the preset time interval, if the detected temperature is still less than the fifth temperature threshold, the transmission rate continues to be increased. In this embodiment, the preset time interval may be greater than the preset time interval during the speed reduction processing, and because a "fast reduction and slow rise" mode is adopted, the back-and-forth fluctuation of the speed can be effectively reduced, and good user experience is brought.
according to the control method of the data transmission equipment provided by the embodiment, the data transmission rate of the equipment is reasonably controlled, so that the overhigh temperature of the equipment can be avoided, the temperature and the rate can be balanced, and the overall performance of the equipment is further improved.
Further, a fourth embodiment of the control method of the data transmission device of the present invention is proposed based on any of the above embodiments. In this embodiment, after step S20, the method of controlling a data transmission apparatus further includes:
and when the acquired temperature is smaller than a sixth temperature threshold, releasing the limitation on the transmission rate and the transmission power of the data transmission equipment, wherein the sixth temperature threshold is smaller than the fifth temperature threshold.
After the transmission rate or the transmission power of the device is limited, the temperature of the device is gradually reduced, and when the obtained temperature is smaller than the sixth temperature threshold, the temperature of the device is considered to be reduced to be low, at this time, in order to ensure that the data of the device can be transmitted at a reasonable rate or works at a reasonable transmission power, the limitation on the transmission rate and the transmission power is removed, further, if the device is in a network disconnection state at present, the network is restarted, and if the device is shut down, the user needs to manually start the device.
the invention also provides a control device of the data transmission equipment.
fig. 3 is a schematic functional block diagram of a control device of a data transmission apparatus according to a first embodiment of the present invention.
In this embodiment, the control device of the data transmission apparatus includes:
An obtaining module 10, configured to obtain a temperature of the data transmission device in a data transmission process of the data transmission device;
and the control module 20 is configured to reduce the transmission rate of the data transmission device according to a limiting manner corresponding to the obtained temperature when the obtained 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 equipment in the embodiment of the invention can be various equipment for data transmission, when the data transmission equipment is used, an SIM card can be installed, the data transmission equipment is communicated with the base station to be connected to the cellular network for data transmission of the cellular network, a WIFI module can be further arranged in the data transmission equipment, wireless communication can be established with other mobile terminals based on the WIFI network, and the mobile terminals can be mobile terminals with WIFI functions such as mobile phones and tablet computers. That is to say, this data transmission equipment can only carry out data transmission under the cellular network, can also regard as the WIFI focus, opens WIFI focus function when establishing cellular network connection, and the user establishes the WIFI connection with this equipment through mobile terminal, realizes the transmission of data. 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, which is implemented by a functional module built in the device, or may be a control device that is independent from the device and can establish a connection with the device. Besides the WIFI hotspot, the mobile terminal may access the data transmission device by using a USB (Universal Serial Bus) data line, an RJ45 network line, and the like, to realize data transmission, where RJ45 is a kind of information socket connector in the wiring system, and "RJ 45" is a common name of a standard eight-bit modular interface.
The data transmission device is provided with a temperature detection device, such as a temperature sensor, or a thermistor, and detects a temperature change through the thermistor, in the data transmission process of the device, the acquisition module 10 acquires the temperature detected by the temperature detection device at regular time or in real time, for example, acquires the temperature every 2-5 seconds, and determines whether the temperature is greater than a first temperature threshold, if so, it indicates that the current device temperature is high and needs to be cooled, and the restriction mode adopted by the control module 20 is related to the magnitude of the acquired temperature.
as an embodiment, the control module 20 is further configured to: when the acquired temperature is greater than a first temperature threshold and less than a second temperature threshold, reducing the transmission rate of the data transmission equipment according to a limiting mode corresponding to the acquired temperature, wherein the first temperature threshold is less than the second temperature threshold;
and when the acquired temperature is greater than the second temperature threshold, reducing the transmitting power of the data transmission equipment according to a limiting mode corresponding to the acquired temperature.
the device may acquire the temperature in real time, and when the temperature is greater than the first temperature threshold, the transmission rate may be limited, and if the detected temperature is greater than the second temperature threshold, the current signal strength may be very weak, or the ambient temperature of the device itself is relatively high, so that the temperature of the device may still not be completely limited after the processing of reducing the transmission rate, and at this time, the control module 20 reduces the transmission power of the device. Because the device automatically increases the transmission power to ensure normal transmission of data when the signal is weak, which causes a rapid temperature rise, the temperature of the device can be reduced by reducing the transmission power, and in order to avoid network interruption or current interruption when the transmission power of the device is reduced, the maximum adjustable transmission power value is determined according to the performance of the chip of the device and the actual use environment, for example, the maximum adjustable transmission power value is gradually reduced by 3-6db each time.
further, as an embodiment, referring to fig. 4, the control module 20 includes:
The cellular network control sub-module 21 is configured to, when the obtained temperature is greater than the first temperature threshold and smaller than a third temperature threshold, decrease a transmission rate of the data transmission device based on a cellular network, where the third temperature threshold is greater than the first temperature threshold and smaller than the second temperature threshold;
And the WIFI network control sub-module 22 is configured to reduce a transmission rate of the data transmission device based on the WIFI network when the obtained temperature is greater than or equal to the third temperature threshold and is less than the second temperature threshold.
When the acquired 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 an uplink transmission rate and a downlink transmission rate. That is to say, 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 smaller than the third temperature threshold, the speed limit processing needs to be performed. By reducing the transmission rate of the cellular network, the temperature of the device may be reduced. In the prior art, the speed reduction is generally performed by adjusting a BSR (Buffer Status Report) parameter, but this speed reduction method can only adjust an uplink transmission rate, and the rate adjustment is limited by a plurality of other factors.
it will be appreciated by those skilled in the art that the first temperature threshold, the second temperature threshold, the third temperature threshold, and the various temperature thresholds to be referred to below may be set by the user as desired.
further, as an embodiment, the control device of the data transmission apparatus further includes:
The marking module is used for marking the state of the data transmission equipment as a speed limit state after the control module reduces the transmission rate of the data transmission equipment based on a cellular network; the cellular network control sub-module 21 includes:
the judging unit is used for judging whether the data transmission equipment is in a speed-limiting state or not when the acquired temperature is greater than the first temperature threshold and less than a third temperature threshold;
an obtaining unit, configured to obtain, if yes, a time interval until a last time transmission rate reduction based on the cellular network;
and the control unit is used for reducing the transmission rate of the data transmission equipment based on the cellular network when the acquired time interval is greater than a preset time interval.
After reducing the cellular network based transmission rate of the data transmission device, a marking module marks the state of the data transmission device as a rate-limited state. Since the temperature is not immediately reduced to be lower than the first temperature threshold value after the rate is just reduced, but a certain time is needed, the marking module marks the device as the speed-limiting state after the transmission rate is reduced, and since the temperature is still detected in real time, when the temperature is detected to be higher than the first temperature threshold value and lower than the third temperature threshold value again, the judging unit judges whether the data transmission device is in the speed-limiting state; if the current time is in a speed-limiting state, the acquisition unit acquires a time interval from the last reduction of the transmission rate based on the cellular network; and when the acquired time interval is greater than a preset time interval, the control unit reduces the transmission rate of the data transmission equipment based on the cellular network.
That is to say, for rate adjustment, a certain sleep time is set, the temperature acquired in this sleep time is not used as a basis for reducing the transmission rate in the cellular network, and when the time interval reaches a preset time interval, if the temperature acquired by the acquisition module 10 is still greater than the first temperature threshold and smaller than the third temperature threshold, the control unit continues to reduce the transmission rate.
as for the manner of reducing the transmission rate, a preset proportion of reduction, for example, 50%, may be set in advance, and each time the transmission rate is reduced, the transmission rate is reduced to 50% of the current transmission rate. The preset time interval may be set according to specific performance of the device and user needs, and optionally, the preset time interval is 20 to 60 seconds, and in an embodiment, the preset time interval is 30 seconds.
Optionally, as an implementation manner, if the device transmits data based on the cellular network and simultaneously transmits data based on the WIFI network and the mobile terminal, the temperature of the device may also increase due to long-time high-rate data mutual transmission based on the WIFI network, and therefore after the speed limit on the cellular network is performed, when the temperature is detected to be greater than the third temperature threshold, the WIFI network control sub-module 22 reduces the transmission rate based on the WIFI network, for example, the rate of the WIFI data may be reduced by controlling the number of packets sent by the WIFI data in a unit time, and because the probability of occurrence of this situation is low in the actual use process, the transmission rate based on the WIFI network is reduced to a lower value, so that the temperature of the device is reduced.
The control device of the data transmission equipment provided by the embodiment acquires the temperature of the equipment in the data transmission process of the data transmission equipment, and limits the transmission rate of the data transmission equipment according to the limitation mode corresponding to the acquired temperature, so as to dynamically adjust the data transmission rate of the equipment according to the temperature of the equipment acquired at regular time, thereby achieving the purpose of adjusting the temperature, avoiding the over-high temperature rise of the equipment caused by the continuous downloading of the data, realizing the effective control on the temperature of the data transmission equipment, improving the stability of the equipment, and simultaneously avoiding the user from being scalded due to the over-high temperature, so as to improve the safety of the equipment.
A second embodiment of the control device of the data transmission apparatus of the present invention is proposed based on the first embodiment. In this embodiment, the control module 20 is further configured to: and when the acquired temperature is greater than a fourth temperature threshold, disconnecting the cellular network of the data transmission equipment, wherein the fourth temperature threshold is greater than the second temperature threshold.
when the ambient temperature of the device itself is higher, if the signal is weaker at this time, the user is performing continuous data transmission again, and the temperature may suddenly rise at this time, so in this embodiment, in order to further improve the overall performance of the device, when it is detected that the temperature is greater than the fourth temperature threshold, the control module 20 disconnects the cellular network connection of the data transmission device, further, if the network is disconnected for a while, the temperature is still higher than the fourth temperature threshold, in order to ensure the safety of the device and the user, the device is controlled to shut down, and shutdown prompt information is output before shutdown.
A third embodiment of the control device of the data transmission apparatus of the present invention is proposed based on the first embodiment or the second embodiment described above. In this embodiment, the control device of the data transmission apparatus further includes:
the marking module is used for marking the state of the data transmission equipment as a speed limit state after the control module reduces the transmission rate of the data transmission equipment based on a cellular network;
The control module 20 is further configured to: and when the acquired temperature is smaller than a fifth temperature threshold value and the data transmission equipment is in a speed limiting state currently, carrying out speed increasing processing on the cellular network of the data transmission equipment, wherein the fifth temperature threshold value is smaller than the first temperature threshold value.
after the control module reduces the cellular network based transmission rate of the data transmission device, a marking module marks the state of the data transmission device as a rate-limited state.
On the premise of controlling the temperature, in order to ensure the normal transmission speed of the data, when it is detected that the temperature is less than a fifth temperature threshold and the current device is marked as a speed-limited state, it indicates that the temperature has been reduced after the speed is limited, where the fifth temperature threshold is less than the first temperature threshold, and at this time, the control module 20 performs speed-up processing on the cellular network of the data transmission device to ensure that the data has a normal transmission speed.
Specifically, when the cellular network based transmission rate of the device is increased, the transmission rate may be gradually increased according to a plurality of preset gears, for example, a five-gear rate is preset, where an uplink rate of a last gear transmission rate is higher than an uplink rate of a next gear, and a downlink rate of the last gear transmission rate is higher than a downlink rate of the next gear. When increasing the transmission rate, the control module 20 first determines that the current rate is in the several gear, and then increases the transmission rate to the previous gear of the current gear.
Further, after each speed increase, the state of the device is marked as the speed increase state, and the device sleeps, the temperature acquired in the sleeping time is not used as a basis for increasing the transmission rate in the cellular network, and when the time interval from the last time of increasing the transmission rate is greater than the preset time interval, if the detected temperature is still less than the fifth temperature threshold, the transmission rate continues to be increased. In this embodiment, the preset time interval may be greater than the preset time interval during the speed reduction processing, and because a "fast reduction and slow rise" mode is adopted, the back-and-forth fluctuation of the speed can be effectively reduced, and good user experience is brought.
The control device of the data transmission equipment provided by the embodiment reasonably controls the data transmission rate of the equipment, so that the overhigh temperature of the equipment can be avoided, the temperature and the rate can be balanced, and the overall performance of the equipment is further improved.
Further, a fourth embodiment of the control device of the data transmission apparatus of the present invention is proposed based on any of the above embodiments. In this embodiment, the control module 20 is further configured to: and when the acquired temperature is smaller than a sixth temperature threshold, releasing the limitation on the transmission rate and the transmission power of the data transmission equipment, wherein the sixth temperature threshold is smaller than the fifth temperature threshold.
after the transmission rate or the transmission power of the device is limited, the temperature of the device is gradually reduced, and when the obtained temperature is smaller than the sixth temperature threshold, the temperature of the device is considered to be reduced to be low, at this time, in order to ensure that the data of the device can be transmitted at a reasonable rate or work at a reasonable transmission power, the control module 20 removes the limitation on the transmission rate and the transmission power, further, if the device is currently in a network disconnection state, the control module 20 restarts the network, and if the device is shut down, the user needs to manually start the device.
