Description

Power supply with output port status monitoring module

The present invention relates to a power supply with an output port status monitoring module, and in particular, to a power supply that enables the status warning component to deactivate the warning only after the microcontroller receives the reset signal.

There are many existing power supplies equipped with prompts to prompt status, such as TW I284797, US 2017192064A, TW M286413, TW 202105879, TW 435893, and TW 201546606, etc.

Take TW I284797 as an example. This patent describes that the power supply detects the power of each load and uses a light signal to indicate the load status. Those notified in the power supply field should know that the power detection of the load mainly detects the output current on the output circuit through the detection component, and then determines the load based on the current value. In addition, TW 202105879 and TW M520671U also fall into the category where current is used as a judgment factor for power supply prompts.

On the other hand, TW M286413 discloses that the power supply has a control circuit connected to the internal fan, and the control circuit is equipped with a temperature sensor. TW M286413 prompts the user to select the set temperature of the power supply through a light signal. When the temperature sensor detects that the temperature of the control circuit reaches the user-selected temperature, the fan starts running. It can be seen from this that the TW M286413 case uses the temperature of the power supply as the judgment factor for the prompt.

However, the current prompting component can only provide a prompting function when the power supply is working. Once the power supply is completely turned off and restarted, the prompting function of the prompting component will also disappear. In practice, most current power supplies are equipped with protection mechanisms. When the power supply reaches the conditions for triggering the protection mechanism, the power supply provides warnings by lighting up lights, displaying screens, etc., and at the same time enters an autonomous control state. In the autonomous control state, the control unit within the power supply forcibly controls the working status of the components, and even forcibly turns off the power supply and restarts it, causing the power supply to temporarily stop working. For example, the power supply has critical current protection. When the output current of the output port triggers the critical current protection, the output current of the output port will be forcibly reduced. At the same time, the power supply can also be equipped with over-current protection. When the output When the output current of the port triggers the over-current protection, the power supply can also forcibly turn off the power, thereby suspending the operation of the output port. However, in the state of autonomous control, most users directly turn off the power supply and forcibly release the protection mechanism. In this way, the user cannot be required to conduct a preliminary inspection of the power supply. Furthermore, after the current power supply automatically turns off the power and restarts, the prompt cannot maintain the warning, so the current power supply cannot prompt the user to check.

The main purpose of the present invention is to solve the problem that the conventional reminder component cannot maintain the warning after the power supply is cut off and restarted.

To achieve the above object, the present invention provides a power supply with an output port status monitoring module, including at least one power output port, at least one status warning component, and at least one output port status monitoring module.

The output port status monitoring module includes at least one temperature sensing component disposed adjacent to the power output port, and a temperature sensing component generated with the temperature sensing component. Information is connected to a microcontroller that senses the output current of the power output port, and a reset signal generator connected to the microcontroller. The microcontroller has at least one port status warning condition, and the port status warning condition is based on the power output port. At least one of a temperature and an output current is used as a judgment factor. When the port status warning condition is met, the microcontroller outputs the warning signal to the status warning component and maintains the status until receiving the reset signal provided by the reset signal generating component. A reset signal.

The detailed description and technical content of the present invention are described as follows with reference to the drawings:

Referring to FIGS. 1 to 4 , the present invention provides a power supply 10 that includes at least one power output port 11 , at least one status warning component 12 and at least one output port status monitoring module 13 . The power output port 11 is located on an output side 101 of the power supply 10 , and is electrically connected to a power conversion module 14 of the power supply 10 . To explain in more detail, the power conversion module 14 includes a power input port 141 electrically connected to an external power source, and a power modulation unit 142 connected to the power input port 141 and the power output port 11 . Generally speaking, the power input port 141 is located at an input side 102 of the power supply 10, and the input side 102 and the output side 101 are respectively located at two ends of the power supply 10. From this, it can be seen that the power input The position of port 141 is opposite to the power output port 11 . The power input port 141 is electrically connected to an external power source equipped with AC power in a room. The power input port 141 obtains an external power from the external power source. In one embodiment, the power input port 141 can be a plug. The power modulation unit 142 receives the external power from the power input port 21 to perform power modulation, and outputs a working power to the power output port 11 . The power modulation method of the power modulation unit 142 can be designed according to implementation requirements. For example, the power modulation unit 142 can include a rectifier filter circuit, a power factor correction circuit, a transformer, a pulse width control unit, A switching element and a rectifier output circuit perform power modulation. During implementation, after receiving the external power, the rectification and filtering circuit rectifies and filters the external power and converts it into DC power for output to the power factor correction circuit, and the power factor correction circuit performs power factor correction and harmonics on the DC power. then the primary side coil of the transformer is connected to the power factor correction circuit to receive the DC power and is connected to the switching element. The primary side coil of the transformer determines the startup or shutdown of the transformer based on the conduction of the switching element. The switching element is turned on or off by a pulse width modulation signal output by the pulse width control unit. When the switching element is turned on, the primary side coil and the secondary side coil of the transformer generate magnetic induction, causing the secondary side coil to generate An induced electricity. Afterwards, the rectification output circuit rectifies the induced power, converts the induced power into the working power, and transmits the working power to the power output port 11 .

Following the above, the output port status monitoring module 13 includes a temperature sensing component 131 disposed adjacent to the power output port 11, a microcontroller 132 connected to the temperature sensing component 131, and a microcontroller 132 connected to the microcontroller 132. Reset signal generating component 133. The power output port 11 produces a change in temperature when outputting the working power. The temperature sensor 131 is disposed close to the power output port 11. The temperature sensor 131 is used to sense the temperature of the housing of the power output port 11. The temperature sensor The component 131 senses the temperature change of the housing of the power output port 11 to generate a temperature signal 130 . It should be noted that the adjacent arrangement referred to in this article can be regarded as the temperature sensing element 131 being placed close to or obviously close to the power output port 11 . In one embodiment, the temperature sensing element 131 can be a thermistor. The thermistor changes its resistance based on the heat it senses, thereby changing the voltage signal of the branch to which the thermistor belongs, and the voltage signal can be viewed This temperature signal is referred to as 130 in this article.

Following the above, the microcontroller 132 receives the temperature signal 130 and is electrically connected to the power output port 11. The microcontroller 132 can be the main work manager of the power supply 10 according to the implementation requirements, or it can be used for some tasks. Logic controller for circuit settings. The microcontroller 132 is connected to the power output port 11 and uses the output current of the power output port 11 as a current signal for determining the status of the power output port 11 in the future. The microcontroller 132 is preloaded with at least one logic operation program, which defines at least one port status warning condition. The main judgment factors of the port status warning condition are the current signal and the temperature signal 130 . When the port status warning condition is triggered, the microcontroller 132 will generate a warning signal 120 . The size of the aforementioned judgment factor can be set based on actual usage requirements, the type and specification of the power output port 11, etc., for example, the port status warning condition can be based on the plurality of temperature signals 130 representing the power output port 11 within a period of time. The microcontroller 132 will not generate the warning signal 120 if the temperature change of the power output port 11 described by the temperature signal 130 is less than the port status warning condition. When the port status warning condition is met, the warning signal 120 is generated. In addition, the port status warning condition can also be based on a single temperature signal 130 as a basis for judgment. For example, when the temperature of the power output port 11 reaches a preset threshold as described in the temperature signal 130, the microcontroller 132 generates the warning signal. 120. Similarly, the port status warning condition can also be judged based on a single current signal or changes in a plurality of current signals, which will not be described again here. In addition, the foregoing article only uses a single judgment factor (such as the temperature signal 130 or the current signal) as an example. In practice, the port status warning condition is not limited to a single judgment factor, and the temperature signal 130 and the current can be integrated. The signal is logically judged using composite factors. Furthermore, the warning signal 120 can take many forms, and can be a potential change of a pin of the microcontroller 132, or a bit stream containing execution content.

Furthermore, the microcontroller 132 generates the warning signal 120 and then transmits it to the status warning component 12 . The status warning component 12 generates at least one visual prompt after receiving the warning signal 120 . It should be understood that the visual prompt generated by the status warning component 12 is intended to prompt a user. That is to say, the visual prompt must be sufficient to attract the user's attention. However, the status warning component 12 Setting the location is not the focus of this article. For example, when the status warning piece 12 is a display screen, the display screen can use text messages, codes or even image marks as the visual prompt. In this embodiment, the status warning piece 12 needs to be displayed on the power supply. The surface of the device 10 is as shown in Figure 7. When the status warning part 12 is a light-emitting part, the light-emitting part uses light, light color changes, light flashing frequency changes, etc. as the visual prompt. Assuming that the casing 15 of the power supply 10 is see-through, the light-emitting component can be disposed in the casing 15. If the casing 15 is not see-through, the luminous component needs to be disposed in the power supply 10. surface. Furthermore, the perspective mentioned in this article can be achieved through the hollows on the housing 15, and is not limited to transparent materials.

Following the above, the reset signal generating component 133 is provided on the power supply 10. The reset signal generating component 133 serves as the person to release the alert state of the status warning component 12. The reset signal generating component 133 generates a reset signal after being operated. 135. After the reset signal 135 is generated, it is transmitted to the microcontroller 132, causing the microcontroller 132 to release the control of the status warning component 12. In one embodiment, the reset signal generating component 133 is a push switch.

Next, the implementation of the power supply 10 will be described. It is assumed that initially, the output current and its own temperature of the power output port 11 do not reach the port status warning condition, and the microcontroller 132 does not output the warning signal 120 to the status warning component 12 . Once the power output port 11 reaches the port status warning condition, the power output port 11 triggers the microcontroller 132 to generate the warning signal 120. The status warning component 12 reads the warning signal 120 and generates the visual prompt. Afterwards, the microcontroller 132 keeps operating. Before the microcontroller 132 receives the reset signal 135, the microcontroller 132 continues to drive the visual prompt to be generated. When the microcontroller 132 receives the reset signal 135, the action of the microcontroller 132 is disabled, causing the status warning component 12 to stop generating the visual prompt. Among them, the aforementioned method of maintaining signals is not the focus of this case. Those with ordinary knowledge in this field can implement it based on the existing technology to achieve the same effect. In order to facilitate readers' understanding, this article will use the following examples to illustrate: For example, when the port status alert condition is triggered, the microcontroller 132 clamps the output power level of the pin until the reset signal 135 is received, so that the microcontroller 132 is maintained before receiving the reset signal 135 Current status, that is, the status warning component 12 is maintained in the warning state; Example 2: The microcontroller 132 sets a clamping voltage on the pin. When the power supply 10 is completely shut down and restarted, the microcontroller 132 fixes the power level of the pin at the clamping voltage again. This is used to maintain the output of the pin. In other words, the microcontroller 132 only stops limiting the power of a pin of the microcontroller 132 connected to the status warning component 12 after receiving the reset signal 135; Example 3: The microcontroller 132 includes at least one non-volatile random access memory. After sending the warning signal 120, the microcontroller 132 uses the non-volatile random access memory to store the warning signal 120. When the microcontroller 132 When the controller 132 is restarted again, the information stored in the non-volatile random access memory still causes the microcontroller 132 to provide the warning signal 120 to the status warning component 12 during operation.

In summary, it can be seen that through the setting of the microcontroller 132 of the present invention, when the port status warning condition is triggered, the microcontroller 132 drives the status warning component 12, and the status warning component 12 prompts the user to check the power supply. Provider 10. More specifically, even if the power supply 10 of the present invention is restarted due to its own abnormal protection mechanism, the microcontroller 132 will continue to drive the status warning component 12 after the power supply 10 completes the restart until receiving The reset signal 135 is used to deactivate the status warning component 12 , thereby truly reminding the user to conduct a preliminary visual inspection of the power supply 10 .

Continuing with the above, please refer to Figures 1 to 4 again. In order to facilitate the user to distinguish the meaning represented by the visual prompt, the microcontroller 132 can be based on the situation that the power output port 11 meets the port status warning condition. Differently, the status warning component 12 is controlled so that the visual prompt has different light changes, different flashing frequencies, etc. For example, when the output current of the power output port 11 reaches the critical current, the visual prompt is a yellow light flashing once per second, and when the output current of the power output port 11 exceeds the critical current, the The visual reminder is that the red light flashes once per second. In another example, when the temperature of the power output port 11 reaches the critical temperature, the visual prompt is a yellow light flashing once every 3 seconds, and when the temperature of the power output port 11 exceeds the critical temperature, The visual reminder is that the red light flashes every 3 seconds.

Following the above, when the power output port 11 of the power supply 10 is configured in plural, the output port status monitoring module 13 includes a plurality of temperature sensing devices 131, and each of the plurality of temperature sensing devices 131 corresponds to a plurality of the power. One of the output port 11 settings. In addition, the visual prompt generated by the status warning component 12 is sufficient for the user to distinguish one of the plurality of power output ports 11 that has been warned. For example, when one of the plurality of power output ports 11 meets the port status warning condition, the visual prompt flashes once per second, and when another one of the plurality of power output ports 11 meets the port status warning condition When a warning condition occurs, the visual prompt flashes twice per second. Similarly, the visual prompt can also be different light signal changes, which will not be described further here.

Continuing with the above, please refer to Figure 2, Figure 3 and Figure 6. The power supply 10 of the present invention can also be provided with a plurality of status warning parts 12. The plurality of status warning parts 12 are respectively the light-emitting parts and respectively correspond to a plurality of the power. At least one of the output ports 11 is set. The microcontroller 132 can control one of the corresponding status warning components 12 based on each of the plurality of power output ports 11 meeting the port status warning conditions. Accordingly, the user can control one of the corresponding status warning components 12 based on the plurality of status warning conditions. The person who generates the visual prompt in the status warning piece 12 distinguishes the plurality of those who generate the abnormality in the status warning piece 12 .

The reset signal generating component 133 is set to issue the reset signal 135 after a continuous number of operations. The continuous number of operations is defined as the reset signal generating component 133 must reach a predetermined number of operations within a short period of time. When the reset signal generating component 133 reaches a predetermined number of operations, When the reset signal 135 is not operated for a certain period of time, the number of operations will be reset to zero.

In another embodiment, please refer to FIGS. 5 and 6 , when the reset signal generating member 133 is disposed on the output side 101 of the power supply 10 , the reset signal generating member 133 does not protrude from the surface of the power supply 10 .

The circuit board 16 can be one of the following: a working motherboard, and a circuit board plugged into the working motherboard. There is a small control board on the power supply 10 , and an output backplane electrically connected to the working motherboard and located on the output side 101 of the power supply 10 .

The hole 151 allows the user to use the power supply 10 through a small instrument. The outside extends in to trigger the reset signal generating component 133 . In this embodiment, the reset signal generating component 133 does not extend out of the hole 151 , which can reduce the risk of the reset signal generating component 133 being accidentally touched.

In one embodiment, the reset signal generating component 133 can be further configured to be pressed for a set period of time before sending the reset signal 135 . That is to say, when the reset signal generating component 133 is pressed for less than the set time, the reset signal generating component 133 does not send out the reset signal 135, thereby reducing the risk of the reset signal generating component 133 malfunctioning due to accidental touching. condition.
