According to the embodiment of the invention, the detection module is arranged on the trunk where the peripheral module of the electronic equipment is located, and is connected with the processor, so that after the detection module is used for collecting current information on the trunk where the peripheral module is located and sending the current information to the processor, the processor judges the leakage condition according to the current information and performs corresponding leakage protection operation according to the leakage condition, thereby realizing detection and leakage protection of the leakage condition of the peripheral module, prolonging the service life of the peripheral module and avoiding safety accidents.
Referring to fig. 4, a flow chart method of a leakage detection method of the present invention is shown. The method is applied to the electronic equipment. The method specifically comprises the following steps:
101, closing the peripheral module for a preset time period, and acquiring current information of a passage where the power management module and the peripheral module are located through the detection module in the preset time period;
Specifically, in order to ensure the accuracy of the detected leakage condition, when the detection is performed, if the peripheral module is already in an on state, the processor turns off the peripheral module for a preset period of time through the control line, and simultaneously turns on an analog-to-digital converter (ADC) through the communication port. After the electric leakage condition is detected, the processor opens the peripheral module, and the open state of the peripheral module is restored. If the peripheral module is already in the off state, the processor maintains the existing state of the peripheral module, and only the analog-to-digital converter (ADC) is turned on through the communication port. During the period, the power management module defaults to continuously supply power to the peripheral module.
After the analog-to-digital converter (ADC) is turned on, the current information on the sampling resistor may be obtained by the ADC for a preset period of time. The analog-to-digital converter (ADC) samples analog current information on the resistor R and converts the analog current information into digital current information, and the processor acquires the digital current information through a communication port so as to carry out subsequent judgment.
In the embodiment of the invention, the preset time period can be 5s, and a person skilled in the art can set a corresponding preset time period according to actual conditions, which are all within the protection scope of the invention.
102, determining whether the peripheral module leaks electricity or not according to the current information;
and 103, if yes, performing leakage protection operation according to the current information.
Specifically, the processor can determine whether the peripheral module is leaked according to the acquired current information, and when the peripheral module is determined to be leaked, the current information can feed back the severity of the leakage, so that corresponding leakage protection operation can be performed according to the current information.
According to the embodiment of the invention, on the basis of the current structure, the processor can close the setting module for a preset time period, and in the preset time period, the detection module is used for acquiring the current information of the paths of the power management module and the peripheral module, so as to determine whether the peripheral module is in electric leakage or not according to the current information, and when the peripheral module is in electric leakage, the electric leakage protection operation is carried out according to the current information. Therefore, the leakage condition of the peripheral module can be detected, corresponding leakage protection operation can be carried out according to the leakage condition, the service life of the peripheral module can be prolonged, and the safety accident is avoided.
Referring to fig. 5, a flowchart of another leakage detection method of the present invention is shown, which is applied to an electronic device. The method specifically comprises the following steps:
in the embodiment of the invention, the user is in a waiting state in the process of powering off the electronic equipment to powering on, and the electronic equipment cannot be operated and used by the user. Therefore, the leakage condition can be accurately detected at this stage. For some peripheral modules, the electronic equipment is still in a good state in the starting-up process, but faults such as electric leakage can occur after the electronic equipment is used for a period of time after the electronic equipment is started up, and at the moment, the electric leakage can be detected under the conditions that the starting-up time of the electronic equipment exceeds a preset time threshold and the electronic equipment enters a sleep state. In the same way, the electronic equipment in the sleep state can not be operated and used by a user, and the more accurate detection of the leakage condition can be ensured. In the embodiment of the invention, the preset time threshold is set to 24 hours, and a person skilled in the art can also set the preset time threshold according to actual requirements. The step of obtaining, by the detection module, current information of a path where the power management module and the peripheral module are located in the preset time period includes: and in the preset time period, acquiring current information on the sampling resistor through the analog-digital converter.
Step 201 is a further limitation of step 101.
in embodiments of the present invention, a variety of different current ranges may be provided. For example, a third current range (N1, N2), a second current range (N3, N4), a first current range (N5, +_j) may be set. Wherein N1< N2< N3< N4 < N5. Specifically, the current information acquired falls in which current range, which is the target current range.
in the embodiment of the present invention, three leakage ranges may be set, which are a third leakage range (n 1, n 3), a second leakage range (n 3, n 5), and a first leakage range (n 5, +_j). Wherein n1< n3< n5. Different leakage ranges represent different leakage levels. Wherein, (n 1, n 3) indicates that the peripheral module is slightly leaked, (n 3, n 5) indicates that the peripheral module is moderately leaked, and (n 5, +_indicates that the peripheral module is severely leaked.
If the target current range corresponds to the third leakage range (n 1, n 3), the peripheral module is slightly leaked; if the target current range corresponds to the second leakage range (n 3, n 5), the moderate leakage of the peripheral module is indicated; and if the target current range corresponds to the first leakage range (n 5 and infinity), the severe leakage of the peripheral module is indicated.
Specifically, the determined target current range falls within the section of which leakage range, which leakage range serves as the target leakage range, and it can be determined that the target current range corresponds to the target leakage range of the peripheral module. For example, the target current range is determined to be the third current range (N1, N2) according to the current information, and if the third current range (N1, N2) is determined to be within the third leakage range (N1, N3), the target leakage range may be determined to be the third leakage range (N1, N3), and the target current range is also determined to correspond to the target leakage range of the peripheral module.
It should be noted that, step 202 and step 203 are sub-steps of step 102. In the embodiment of the application, whether the target current range corresponds to the target leakage range of the peripheral module can be determined directly by judging whether the target current range falls in the section of which leakage range.
And 204, if the target current range corresponds to the target leakage range of the peripheral module, executing target leakage protection operation corresponding to the target leakage range according to the corresponding relation between the preset leakage range and the leakage protection operation.
In the embodiment of the invention, a corresponding relation table between the leakage range and the leakage protection operation is preset. When the leakage range is the third leakage range, the processor judges that the peripheral module belongs to normal slight leakage, and then the leakage protection operation is as follows: the processor does not take any action. When the leakage range is the second leakage range, the processor judges that the peripheral module has larger leakage, and then the leakage protection operation is as follows: the processor gives control of whether to turn off the peripheral module to the user for selection. When the leakage range is the first leakage range, the processor judges that the peripheral module has serious leakage, potential safety hazard can be generated, and leakage protection operation is as follows: the processor forces the peripheral module to turn off.
Optionally, when the target current range is a first current range, and the first current range corresponds to a first leakage range, the power management module is controlled to stop supplying power to the peripheral module, and the power supply to the peripheral module is prompted to be disconnected.
Specifically, when the target current range is a first current range (N5, infinity), and the first current range (N5, infinity) corresponds to the first leakage range (N5, infinity), the processor determines that the external module has serious leakage, and in order to prevent the electronic device from generating serious heating and even safety accidents, after the power management module on the trunk where the external module is located is forcibly turned off, the display interface of the electronic device displays prompt information to inform the user that the external module is forcibly turned off.
Optionally, displaying an operation control in a display interface under the condition that the target current range is a second current range and the second current range corresponds to a second leakage range;
receiving a first input to the operational control;
and responding to the first input, controlling the power management module to continuously supply power to the peripheral module or controlling the power management module to stop supplying power to the peripheral module.
Specifically, in the case where the target current range is the second current range (N3, N4), and the second current range (N3, N4) falls within the interval of the second leakage range (N3, N5), the second current range corresponds to the second leakage range. At this time, when the processor judges that the external module has the electric leakage with a large degree but without generating potential safety hazards, the display interface of the electronic equipment displays operation controls and prompt information, so that the user is given the option, and the experience degree of the user is improved. For example, as shown in fig. 6, a display interface schematic of an electronic device is shown. The display interface of the electronic device 1 displays the prompt message 2: the camera has a large degree of electric leakage, whether the camera is closed or not, and two operation controls 3 of yes and no are displayed. And when the user triggers yes, the power management module on the trunk where the peripheral module is located is turned off. And when the user triggers no, the power management module on the trunk where the peripheral module is positioned is not closed. It should be noted that, after the user selects to turn off the power management module on the trunk where the peripheral module is located, the processor does not turn on the power management module any more until the user manually selects to turn on again.
Optionally, in a case where the target current range is a third current range, the third current range corresponds to a third leakage range, the leakage protection operation is not performed.
Specifically, when the target current range is the third current range and the third current range corresponds to the third leakage range, it is indicated that the peripheral module is only normally slightly leaked, the influence on the whole machine is not great, and the leakage protection operation is not required to be executed.
Optionally, the method further comprises: pre-testing the reference leakage current of the peripheral module when the peripheral module is closed; and determining each leakage range according to the reference leakage current.
In particular, it is considered that the peripheral module itself has slight leakage due to a manufacturing process or the like when shipped from the factory. Therefore, when the peripheral module leaves the factory, a person skilled in the art can test the reference leakage current of the peripheral module when the peripheral module is closed in advance, and determine each leakage range according to the reference leakage current. For example, if the reference leakage current of a certain peripheral module is 5mA, the third leakage range is preferable (5 mA,10 mA), the second leakage range is preferable (10 mA,15 mA), and the first leakage range is preferable (15 mA,20 mA).
The third leakage range (n 1, n 3) may be further subdivided into (n 1, n 2) and (n 2, n 3). If the target leakage range corresponding to the target current range is (n 1, n 2), the peripheral module is normal in leakage, and the processor does not need to act; if the target leakage range corresponding to the target current range is (n 2, n 3), the peripheral module is slightly leaked, but the influence on the user is small, and the processor still does not need to act. The second leakage range (n 3, n 5) described above may be further subdivided into (n 3, n 4) and (n 4, n 5). If the target electric leakage range corresponding to the target current range is (n 3, n 4), the peripheral module is in electric leakage to a certain extent, the processor controls the display interface to display operation control and normal prompt information, and the user selects the operation control and the normal prompt information independently; if the target leakage range corresponding to the target current range is (n 4, n 5), the peripheral module is in greater leakage, and the processor controls the display interface to display an operation control and alarm prompt information, and is selected by the user. The person skilled in the art can set different leakage ranges and leakage protection operations according to actual needs, and the invention is not limited to the leakage ranges.
According to the embodiment of the invention, on the basis of the current structure, the processor can close the setting module for a preset time period, and in the preset time period, the detection module is used for acquiring the current information of the paths of the power management module and the peripheral module, so as to determine whether the peripheral module is in electric leakage or not according to the current information, and when the peripheral module is in electric leakage, the electric leakage protection operation is carried out according to the current information.
