The signal terminals are distributed in various places around the world, and some signal terminals are distributed in cold north and south poles or in places with large temperature difference change. Because the chip and the components in the signal terminal cannot directly work in a low-temperature environment, the signal terminal needs to provide a temperature environment for operating the signal terminal externally in the low-temperature environment. The heating device for providing heat for the signal terminal in the prior art comprises a control system, a temperature acquisition module, a heating module and a direct-current power supply. The working principle of the heating device is that under the condition that 220V alternating current is connected, direct current power supplies such as PSUs directly supply power to the heating modules, and the heating modules in the heating device stop working until the starting condition of the signal terminal is met. However, the temperature of the signal terminal may drop to an inoperable state again, which may require the heating module to be restarted for reheating. Therefore, the heating module in such a heating device is repeatedly activated in cold conditions and is continuously heated to maintain the operating temperature requirement of the system. Therefore, the operation of the signal terminal is unstable and energy is wasted due to high power consumption caused by repeated restart of the heating module.
Therefore, a heating device is needed to solve the technical problem that the heating device with the heating function needs to be started repeatedly in the prior art.

In order to make the objects, technical solutions and advantages of the present invention clearer, the present invention will be described in further detail with reference to the accompanying drawings, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
The embodiments of the present invention will be described in further detail with reference to the drawings attached hereto.
Fig. 1 is a schematic structural diagram of a heating apparatus provided in an embodiment of the present invention, and as shown in fig. 1, the heating apparatus 100 includes a temperature collector 110, a processor 120, a heating module 130, a voltage regulator 140, and a dc power supply 150.
The heating device 100 in the embodiment of the present application is provided with the temperature collector 110 for collecting the heated device 160 externally, and when in use, the temperature collector 110 is arranged on the heated device 160, so that temperature collection and processing can be performed on any external device. In the existing mode, temperature reporting is often performed through a temperature collector carried by the heated equipment, and a transmission interface needs to be set between the heated equipment and the heating equipment. Meanwhile, as the heated devices may be different from each other, various types of transmission interfaces need to be developed, so that the workload of temperature acquisition is relatively large.
After acquiring the first temperature of the heated device 100, the processor 120 determines an adjustment signal for adjusting the voltage regulator 140 according to the first temperature and outputs the adjustment signal to the voltage regulator 140; the voltage regulator 140 is configured to adjust the voltage of the heating module 130 according to the adjustment signal, so as to change the operating state of the heating module 130 and implement dynamic change of the operating state of the heating module 130.
The processor 120 determines the adjustment signal according to the first temperature, for example, when the first temperature is lower than a first set threshold, the heating module is controlled to be in a full power state, so as to realize centralized rapid heating of the heated device; after the heated equipment meets the starting condition, controlling the heating module to work in a set power state, thereby realizing continuous low-power heating of the heated equipment and enabling the heated equipment to be in a stable working environment; when the first temperature is higher than the second set threshold value, the heating module can be controlled to stop heating or work in a lowest-power mode.
A heating module 130 for generating heat; the specific implementation manner of the method can be various, such as a heating rod, a heating wire and the like. The heating module 130 may also be a heating plate, which may be composed of a heating material and an insulating material, wherein the heating material and the insulating material may be wrapped by an aluminum plate or a stainless steel plate. The heating material can be iron-aluminum alloy, nickel-chromium alloy, electrothermal alloy wire, etc., and the insulating material can be mica, ceramic, etc. Of course, the shape of the heated device 160 can be varied, and the size of the heating module can be customized according to the shape of the heated device 160, so that the heated device 160 can be better heated.
When the heating module 130 is a heating plate, the heated device 160 may be provided on the heating plate, or a plurality of heated devices may be provided on both surfaces of the heating plate. The specific number of heated devices 160 depends on the size of the heating plate and the heated devices 160; in general, one heating apparatus 100 may heat a plurality of heated apparatuses 160 at the same time, or a corresponding heating apparatus 100 may be provided for each heated apparatus 160.
The dc power supply 150 is configured to supply power to each component in the heating device, and may be implemented by directly accessing a mains supply or by using an external energy storage battery.
The heating device 100 and the heated device 160 in the embodiment of the present application may both be in the same external environment, one heating device 100 may heat a plurality of heated devices 160 at the same time, or a corresponding heating device 100 may be configured for each heated device 160.
Fig. 2 is a schematic diagram of an operating principle of a heating device according to an embodiment of the present invention, and as shown in fig. 2, the temperature collector 110 includes a first temperature collector 201 and a second temperature collector 202, where the first temperature collector 201 collects first temperatures of at least 5-10 monitoring points arranged on the heated device through a multi-channel DAC converter; the second temperature collector 202 collects second temperatures of at least 5-10 monitoring points arranged on the heating module through a multi-channel DAC; the processor 120 determines an adjustment signal based on the first temperature and the second temperature. The multipoint temperature acquisition is carried out through the temperature acquisition device, so that the accuracy of the acquired temperature can be ensured, and the unsustainability when the single-point temperature acquisition fails is avoided; meanwhile, the running health state of the heating equipment can be monitored more comprehensively through the first temperature and the second temperature which are fed back to the processor.
The processor is specifically used for enabling the heating module to be in a full-power state through the adjusting signal when the first temperature is lower than a first set threshold; when the first temperature is higher than the first set threshold and lower than a second set threshold, gradually reducing the power of the heating module to a steady state through the adjusting signal so that the first temperature and the second temperature tend to be within a range of a third set threshold; when the first temperature is higher than the second set threshold value, the heating module stops working through the adjusting signal; the second set threshold is higher than the third set threshold.
In the embodiment of the present invention, the voltage regulator 140 adjusts the voltage of the heating module 130 according to the adjustment signal, specifically, the input end of the voltage regulator is provided with the current collector 203 for collecting the input current of the voltage regulator 140, the processor 120 determines the adjustment signal according to the input current, the first temperature and the second temperature, the processor 120 sends the adjustment signal to the voltage regulator 140, and the voltage regulator 140 adjusts the voltage of the heating module 130 according to the adjustment signal.
As shown in fig. 3, a specific implementation of the voltage regulator 140 is provided, and the voltage regulator includes a microprocessor 310, an adjustable resistor 320, a transformer 330 connected in parallel with the adjustable resistor, a first switch 340 connected in series with the adjustable resistor, and a second switch 350 located on an input path of the power input terminal. The adjustment signal received by the microcontroller 310 is a pulse width modulation PWM duty cycle, wherein pulse width modulation is an analog control method. When the PWM output is used to indicate full load operation of the heating module 130, the microcontroller 310 controls the first switch 340 to be closed and the second switch 350 to be opened, so that the heating module 130 is operated at full load through the transformer 330; when the PWM output is used to indicate that the heating module 130 is in the dynamic power mode of operation, the microcontroller 310 controls the first switch to be closed and the second switch to be closed; meanwhile, the output voltage of the transformer 330 is changed by adjusting the resistance value of the adjustable resistor; when the PWM output is used to indicate that the heating module 130 is out of operation, the microcontroller 310 controls the first switch 340 to be open and the second switch 350 to be open. Specifically, the voltage regulator 140 includes a microcontroller 310, and the microcontroller 310 can adjust the output voltage according to a duty cycle of the PWM signal, wherein the duty cycle of the PWM signal is proportional to a turn ratio of the adjustable resistor 320, and when the duty cycle of the PWM signal changes, the resistance of the adjustable resistor 320 changes accordingly. Since the transformer 330 and the adjustable resistor 320 are connected in parallel, the output voltage of the voltage regulator 140 can be changed by changing the resistance of the adjustable resistor 320. Since the voltage regulator 140 is connected in series with the heater module 130 and the processor 120, and the voltage of the processor 120 is constant, when the output voltage of the voltage regulator 140 changes, the voltage of the heater module 130 changes accordingly.
The embodiment of the present invention further includes a sub-heating module 204, and the sub-heating module 204 is configured to heat the processor 120. Specifically, when the heating apparatus 100 is just powered on, the external environment temperature at this time is low, neither the processor 120 nor the heated apparatus 160 reaches the power-on condition, and both the sub-heater modules 204 and 130 operate under the default control, which is to make both the heater modules 130 and the sub-heater modules 204 operate fully. After the temperature reaches the power-on condition of the processor 120, the processor 120 starts to receive the first temperature and the second temperature fed back by the temperature collector 110, and then the generated adjusting signal controls the voltage of the heating module 130.
Fig. 4 is a heating power curve variation diagram according to an embodiment of the present invention, in which the heating module is in a full-load operating state when the heating device is just powered on, until the temperature heated by the heating module reaches a power-on condition of the heated device, the processor determines an adjustment signal according to the input current, the first temperature, and the second temperature, and the voltage regulator controls the voltage of the heating module according to the adjustment signal, so as to adjust the heating power of the heating module. For example, when the first temperature is lower than-20 ℃, the pressure regulator adjusts the heating power of the heating module to a full power state according to the adjusting signal, so that the starting time of the heated equipment can be saved; when the first temperature rises to about 5 ℃, the pressure regulator enables the power of the heating module to start to drop to a stable state again according to the adjusting signal after the heated equipment is started, and the first temperature and the second temperature are stabilized between 20 ℃ and 25 ℃. The heating module is always in operation and has the function of keeping the temperature of the heated equipment between 20 ℃ and 25 ℃. But the heated equipment can generate heat during working, and when the heat generated by the heated equipment can sufficiently meet the required working environment, the pressure regulator can stop the heating module according to the adjusting signal.
Fig. 5 is a graph showing heating time curves of a heating module and a heated device according to an embodiment of the present invention, and as shown in fig. 5, the heating system temperature indicates the temperature of the heating module, and the heated system temperature indicates the temperature of the heated device. After the heating device 100 starts to be started, when the temperature is low, the voltage regulator 140 makes the power of the heating module 130 to be in a full power state according to the adjustment signal, so the temperature of the heating module 130 is high at the beginning, and the temperature of the heated device 160 is low at the beginning because the environment is cold. When the temperature of the heated device 160 meets the start-up condition, the voltage regulator 140 adjusts the heating power of the heating module 130 again according to the adjustment signal, and at this time, the heating power of the heating module 130 starts to decrease to a stable state, so that the first temperature and the second temperature are both stabilized within the start-up condition of the heated device 160. This is to avoid the damage of the parts caused by the over-high temperature of the heated device 160, and the heating module 130 is always in the working state at this time, so that the heated device 160 will not be unstable due to the repeated start of the heating module 130.
Fig. 6 is a flowchart of a method for adjusting a temperature of a heating device according to an embodiment of the present invention, where the flowchart may be executed by processor 120.
As shown in fig. 6, the process specifically includes:
The temperature collector feeds the collected temperature back to the processor. Wherein the collected temperatures are divided into a first temperature and a second temperature. The first temperature is the temperature of the heated equipment, and the second temperature is the temperature of the heating module.
The processor determines an adjusting signal according to the temperature threshold value of the first temperature, and the voltage regulator adjusts the voltage of the heating module according to the adjusting signal.
The processor determines the adjusting signal again according to the temperature threshold value of the first temperature, and the voltage regulator adjusts the voltage of the heating module again according to the adjusting signal.
And step 604, enabling the heating module to be in a full power state according to the adjusting signal.
When the first temperature is lower than a first set threshold value, the pressure regulator enables the heating module to be in a full-power state according to the adjusting signal.
And 605, starting to reduce the power of the heating module to a stable state according to the adjusting signal to ensure that the first temperature and the second temperature are both stabilized within a third set threshold range.
When the first temperature is higher than the first set threshold and lower than the second set threshold, the power of the heating module starts to be reduced to a stable state according to the adjusting signal so as to ensure that the first temperature and the second temperature both tend to be within the range of the third set threshold.
And step 606, stopping the heating module according to the adjusting signal.
When the first temperature is higher than the second set threshold value, the heating module stops working in order to avoid damaging parts of the heated equipment due to high temperature.
In the embodiment of the utility model, when the heated equipment meets the starting-up condition, the heated equipment starts to work, the heated equipment in the working state can generate heat, and when the heat generated by the heated equipment can reach the starting-up condition of the heated equipment, if the heated equipment is still heated by the heating module, the temperature of the heated equipment is overhigh due to the heat of the heated equipment and the heat provided by the heating module, so that parts in the heated equipment are damaged due to high temperature. In order to avoid this, a heat dissipation fan is added to the heating apparatus. Specifically, when the first temperature collected by the temperature collector is higher than a second set threshold value, the processor generates an adjusting signal according to the first temperature and the second temperature and sends the adjusting signal to the voltage regulator, and the voltage regulator enables the heating module to stop working according to the adjusting signal. The heating module can cool off gradually after the stop work, because the outsourcing of heating module is aluminum plate or corrosion resistant plate, the surface temperature of heating module can be very low after the heating module cooling, can be cooled down for being in the heated equipment under the high temperature state as the heat abstractor by heated equipment this time. Meanwhile, the heat dissipation fan arranged on the heating plate can be started to dissipate heat for the heated equipment.
