As described in the background art, due to the limitation of screen materials, when the segment code screen works under the condition of low temperature, the screen refresh rate is reduced, so that the screen is blurred, the data display is unclear, and the screen information cannot be effectively identified.
In view of the above, the present application provides a segment code screen driving system, which can normally use Duan Ma screen even at low temperature by providing a heat pipe for heating and a backlight board for preheating Duan Mabing.
The following describes an exemplary segment code screen driving system provided by the application:
As an implementation manner, referring to fig. 1, the segment code screen driving system 100 includes a controller 110, a display module 130, a temperature sensor 120, a heat conducting tube 140 and an energy supply module, wherein the controller 110 is electrically connected with the display module 130, the temperature sensor 120 and the energy supply module 150, the heat conducting tube 140 is connected with the energy supply module 150 and the display module 130, the display module 130 includes backlight plates 131 and Duan Mabing, and the temperature sensor 120 is further connected with the segment code screen 132. The energy supply module 150 is configured to supply energy to the controller 110, the display module 130, and the temperature sensor 120, the heat pipe 140 is configured to transfer heat generated during operation of the energy supply module 150 to the segment code screen 132, the temperature sensor 120 is configured to collect a current temperature of the Duan Ma screen 132, the controller 110 is configured to determine a current start mode according to a comparison result between the current temperature and a preset temperature when receiving a start command, and when the current start mode is a cold start mode, the controller 110 is configured to regulate and control a light intensity of the backlight plate 131 so as to preheat the segment code screen 132.
The temperature sensor 120 is installed at the rear end of the screen and is used for collecting the temperature of the screen; the energy supply module 150 is a module that can provide energy for the system operation, such as a battery, and the battery can generate heat during normal operation, and the heat conduction pipe 140 can transfer the heat of the battery to the segment screen 132, so as to heat the segment screen. It will be appreciated that the module connected to the heat pipe 140 may not be limited to the energy supply module 150, but may be any module that may generate an additional heat source during operation, such as an inverter or the like.
Optionally, the heat conducting tube 140 is a copper tube with a cooling liquid inside, one end of the heat conducting tube 140 is connected to a module capable of generating heat, and the other end is in backlight contact with Duan Mabing 132,132. The heat pipe 140 is a heat transfer element having extremely high heat conductive property, which transfers heat by evaporation and condensation of liquid in a totally enclosed vacuum tube, and which achieves heat transfer effect by using fluid principles such as capillary action.
Here, it should be noted that, the modules connected to the heat conducting pipe 140 are all modules inside the Duan Ma screen driving system 100, so that on one hand, no additional cost is added; on the other hand, the heat generated by the internal module is utilized to heat the segment code screen 132, so that the energy is recycled, and meanwhile, the heat generated by the module can be dissipated. For example, when the heat pipe 140 is connected to the battery, since a large amount of heat is generated during the operation of the battery, the temperature of the battery is significantly raised during the operation, and by providing the heat pipe 140, a significant cooling effect can be achieved for the battery.
The control board is used for complete machine control, and has the functions of realizing numerical conversion, backlight driving and Duan Mabing 132,132 driving of the temperature sensor 120. The backlight plate 131 provides a backlight source for the segment code screen 132, the backlight plate 131 adopts high-brightness LED lamp beads, a certain margin is reserved for the maximum power of the lamp beads, and the full-load operation can be realized under special conditions so as to heat the screen. The segment code screen 132 is a display unit for man-machine interaction and information display.
Meanwhile, the segment code screen 132 is in contact with the backlight component structurally, so that the temperature of the Duan Ma screen 132 can be obviously increased when the illumination intensity of the backlight plate 131 is increased.
In addition, the Duan Ma panel driving system 100 further includes a backlight driving circuit 133 and a screen driving circuit 134, the backlight driving circuit 133 is electrically connected to the backlight panel 131 and the controller 110, and the screen driving circuit 134 is electrically connected to the Duan Ma panel 132 and the controller 110, respectively. The backlight driving circuit 133 is used for driving the backlight 131 to operate, and the maximum current of the circuit can meet the requirement of long-time operation of the backlight 131 under full load. The screen driving circuit 134 is used for driving the segment code screen 132 to work, and has bias voltage and refresh rate adjusting functions.
According to the segment code screen driving system 100 provided by the application, on one hand, the Duan Mabing is preheated by adjusting the luminous intensity of the backlight plate 131, so that the temperature of the segment code screen 132 can be regulated and controlled in an active temperature control mode, and the segment code screen driving system can be normally started under the low temperature condition. On the other hand, due to the heat conducting pipe 140, heat generated by the energy supply module during operation can be transferred to the segment code screen 132, and heat dissipation of the energy supply module is realized on the basis of heating of the segment code screen 132.
The preset temperature comprises a first preset temperature and a second preset temperature, and the value of the second preset temperature is larger than that of the first preset temperature;
The controller 110 is further configured to determine that the current start-up mode is a start-up disabled mode when the current temperature is less than a first preset temperature; when the current temperature is between the first preset temperature and the second preset temperature, determining that the current starting mode is a cold starting mode; and when the current temperature is greater than the second preset temperature, determining that the current starting mode is a normal starting mode.
The start-disabled mode refers to that the current temperature is too low, the segment code screen 132 cannot be driven to work, and the cold start mode refers to that the current temperature is low, and the segment code screen 132 needs to be preheated, so that the segment code screen 132 cannot fail after being started. The normal start mode refers to the fact that the temperature of the segment code screen 132 is relatively good, and can be directly and normally operated.
For example, the first preset temperature is set to-40 ℃ and the second preset temperature is set to 0 ℃. If the temperature detected by the current sensor is-50 ℃, the temperature is lower than the limit temperature, the system cannot work normally, and the controller 110 cannot drive the segment code screen 132 to display even if receiving a starting instruction. For example, the start mode is a start button, and the segment code screen 132 does not respond when the start button is pressed. If the temperature detected by the temperature sensor 120 is-20 ℃, it indicates that the code screen 132 can be normally started in this time period, but because the current temperature is low, the problems of screen grazing, unclear data display and the like may occur, so that the code screen 132 needs to be preheated. The application adopts a mode of controlling the light emitting intensity of the backlight plate 131 to heat Duan Mabing 132,132. If the temperature detected by the temperature sensor 120 is 20 ℃, it indicates that the time period code screen 132 is not placed in a low-temperature environment, and the time period code screen 132 can be directly started without preheating.
It should be noted that, when in the cold start mode, the temperature of the illumination intensity segment code screen 132 of the backlight plate 131 is related to a dynamic process, that is, the controller 110 is further configured to reduce the light intensity of the backlight plate 131 when the temperature of the segment code screen 132 increases, and to control the backlight plate 131 to emit light according to the preset light intensity when the temperature of the segment code screen 132 increases to be greater than or equal to the second preset temperature.
Referring to fig. 2, fig. 2 is a schematic diagram showing a correspondence between the light intensity of the backlight 131 and the temperature of Duan Ma screen 132, wherein the abscissa of the diagram represents the temperature of the segment code screen 132 and the ordinate represents the light intensity of the backlight 131. On this basis, the controller 110 may prestore a correspondence relationship between the temperature and the backlight 131. The lower the temperature of the segment code screen 132, the higher the light output intensity of the backlight plate 131. With continued reference to fig. 2, it can be seen that when the temperature of the segment code screen 132 approaches the limit temperature (i.e., the first preset temperature), the light output intensity of the backlight plate 131 can reach 150%, and when the temperature of the segment code screen 132 gradually increases, the light output intensity of the backlight plate 131 gradually decreases until the light output intensity of the backlight plate 131 reaches a stable value when the temperature of the segment code screen 132 increases to be greater than or equal to the second preset temperature, at this time, the light output intensity is 100%, and no longer decreases thereafter.
Here, it should be noted that, when the current start mode is the normal start mode, the backlight 131 directly emits light according to the light intensity of 100% when the light intensity is 100%.
It should be further noted that, after the Duan Ma screen driving system 100 is started, as the energy supply module continuously generates heat during operation, the heat is continuously transferred to the segment code screen 132 through the heat conduction pipe 140, so that the temperature of the segment code screen is continuously increased, therefore, the heat generated by the light intensity required by the segment code screen 132 is gradually smaller, and the light output intensity of the backlight plate 131 can be continuously reduced. As an implementation manner, in order to more conveniently control the light output intensity of the backlight plate 131, the application adopts a PID adjustment manner to realize the adjustment of the light output intensity of the backlight plate 131. That is, the controller 110 continuously obtains the current temperature collected by the temperature sensor 120, and determines the intensity of the light emitted by the backlight 131 at this time according to the correspondence relationship, so as to achieve the effect of adjusting the intensity of the light emitted by the backlight 131 in real time until the intensity of the backlight 131 tends to be stable.
In addition, in order to ensure normal starting under the low-temperature condition, optionally, the controller is further used for reducing the refreshing frequency and the bias voltage of the segment code screen when the current starting mode is the cold starting mode.
Referring to fig. 3, fig. 3 shows a graph of a temperature of a segment code screen versus a refresh period, wherein an abscissa is Duan Mabing temperature, and an ordinate is a refresh period, and when the temperature of the segment code screen increases, the refresh period decreases, so that the refresh frequency increases. By increasing the refresh period mode of the segment code screen, the effect of preventing the segment code screen from generating ghosts can be achieved.
Referring to fig. 4, fig. 4 shows a graph of a temperature of a segment code screen and a bias voltage, wherein an abscissa is Duan Mabing temperature, and an ordinate is bias voltage, and when the temperature of the segment code screen increases, the bias voltage increases. Because the low-temperature liquid crystal of the segment code screen is inert, when the segment code screen is in a low-temperature environment, the offset voltage value is properly reduced, and the problem of slow screen refreshing can be effectively relieved.
It can be understood that the working principle of the segment code screen driving system provided by the application is as follows:
When the device is started in the cold start mode, the controller can adjust parameters such as the refreshing frequency of the segment code screen, the bias voltage value, the light emitting intensity of the backlight plate and the like according to the data table. The screen is inert under the low temperature condition due to the low temperature of the segment code screen crystal, so that the refreshing frequency of the screen can be reduced along with the reduction of the temperature. After starting, the temperature is acquired based on the temperature sensor, and the active preheating work is carried out on Duan Mabing by adopting the intensity adjustment of backlight. The whole algorithm performs temperature closed-loop control based on the PID algorithm, so that the temperature of the Duan Ma screen is quickly increased after cold start, and the Duan Ma screen is enabled to work at a proper temperature. When the system works normally, the module generating heat inside can generate redundant heat, and the heat can be released into the air by self-cooling or air-cooling, and in the application, the heat conducting pipe is directly communicated with the backlight panel and the heat generating equipment, so that the heat conducting pipe can transfer the redundant heat to the backlight of the screen, thereby passively heating the screen until the temperature of the screen reaches a second preset temperature.
Based on the implementation manner, the embodiment of the application also provides a segment code screen driving method, which is applied to the controller in the segment code screen driving system, referring to fig. 5, and the method comprises the following steps:
S102, when a starting instruction is received, determining a current starting mode according to a comparison result of the current temperature of the segment code screen and a preset temperature.
S104, when the current starting mode is the cold starting mode, regulating and controlling the luminous intensity of the backlight plate so as to preheat the segment code screen.
Optionally, the method further comprises:
When the current starting mode is a cold starting mode, the refreshing frequency and the bias voltage of the segment code screen are reduced.
The preset temperature comprises a first preset temperature and a second preset temperature, and the value of the second preset temperature is larger than that of the first preset temperature; the step of determining the current starting mode according to the comparison result of the current temperature of the segment code screen and the preset temperature comprises the following steps:
When the current temperature is smaller than the first preset temperature, determining that the current starting mode is a forbidden starting mode;
When the current temperature is between the first preset temperature and the second preset temperature, determining that the current starting mode is a cold starting mode;
and when the current temperature is greater than the second preset temperature, determining that the current starting mode is a normal starting mode.
Optionally, the step of adjusting the light intensity of the backlight plate to preheat the segment code screen includes:
when the temperature of the segment code screen is increased, controlling the light intensity of the backlight plate to be reduced;
When the temperature rise of the segment code screen is larger than or equal to the second preset temperature, the backlight plate is controlled to emit light according to the preset light intensity.
Optionally, after the step of determining the current start mode according to the comparison result of the current temperature of the segment code screen and the preset temperature, the method further includes:
when the current starting mode is the normal starting mode, the backlight plate is controlled to emit light according to the preset light intensity.
Referring to fig. 6, fig. 6 is an exemplary flowchart of the segment code screen driving method according to the present application, and since the above embodiment has already described the segment code screen driving method in detail, a detailed description thereof will be omitted herein.
In summary, the present application provides a segment code screen driving system and a segment code screen driving method, where the segment code screen driving system includes a controller, a display module, a temperature sensor, a heat pipe, and an energy supply module, the controller is electrically connected to the display module, the temperature sensor, and the energy supply module, the heat pipe is connected to the energy supply module and the display module, the display module includes a backlight plate and Duan Mabing, and the temperature sensor is also connected to the segment code screen; the energy supply module is used for supplying energy to the controller, the display module and the temperature sensor, the heat conducting pipe is used for transferring heat generated during operation of the energy supply module to the segment code screen, the temperature sensor is used for collecting the current temperature of the segment code screen, the controller is used for determining a current starting mode according to a comparison result of the current temperature and a preset temperature when receiving a starting instruction, and the controller is used for regulating and controlling the luminous intensity of the backlight plate when the current starting mode is a cold starting mode so as to preheat the segment code screen.
