According to the embodiment of the invention, the detection module is arranged on the trunk where the peripheral module of the electronic equipment is arranged, 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 arranged and sending the current information to the processor, the processor judges the electric leakage condition according to the current information and performs corresponding electric leakage protection operation according to the electric leakage condition, thereby realizing the detection and the electric leakage protection of the electric leakage condition of the peripheral module, prolonging the service life of the peripheral module and avoiding safety accidents.
Referring to fig. 4, a flowchart 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:
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 closes the peripheral module for a preset time period through a control line, and simultaneously opens the analog-to-digital converter (ADC) through the communication port. And after the electric leakage condition is detected, the processor opens the peripheral module again to recover the starting state of the peripheral module. If the peripheral module is in the closed state, the processor maintains the existing state of the peripheral module, and only the analog-digital converter (ADC) is opened through the communication port. In the meantime, the power management module defaults to continuously supply power to the peripheral module.
After an analog-digital converter (ADC) is turned on, current information on a sampling resistor can be acquired through the ADC within a preset time period. 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 the communication port so as to perform subsequent judgment.
In the embodiment of the present invention, the preset time period may be 5s, and those skilled in the art may set a corresponding preset time period according to actual situations, all of which are within the protection scope of the present invention.
102, determining whether the peripheral module leaks electricity 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 leaks electricity according to the acquired current information, and when the peripheral module leaks electricity, the severity of the electricity leakage can be fed back by the current information, so that corresponding electricity 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 preset module for the preset time period, and in the preset time period, the detection module acquires the current information of the path where the power management module and the peripheral module are located, so as to determine whether the peripheral module leaks electricity according to the current information, and when the peripheral module leaks electricity, the leakage protection operation is performed according to the current information. Therefore, the effects that the electric leakage condition of the peripheral module can be detected, the corresponding electric leakage protection operation can be carried out according to the electric leakage condition, the service life of the peripheral module can be prolonged, and safety accidents are avoided are achieved.
Referring to fig. 5, a flow chart 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, in the process from power-off to power-on of the electronic equipment, the user is in a waiting state, and the electronic equipment cannot be operated and used by the user. Therefore, the leakage condition can be accurately detected at the stage. For some peripheral modules, the electronic equipment is still in a good state in the starting process, but faults such as electric leakage and the like can occur after the electronic equipment is used for a period of time after the electronic equipment is started, and at the moment, the electric leakage can be detected under the condition that the starting time of the electronic equipment exceeds a preset time threshold and the electronic equipment enters a sleep state. Similarly, the electronic equipment in the sleep state can not be operated and used by a user, and the electric leakage condition can be accurately detected. In the embodiment of the present invention, the preset time threshold is set to 24h, and those skilled in the art may also perform corresponding setting according to actual requirements. In the preset time period, obtaining, by the detection module, current information of a path where the power management module and the peripheral module are located includes: and acquiring current information on the sampling resistor through the analog-digital converter within the preset time period.
Step 201 is a further limitation of step 101.
in embodiments of the present invention, a variety of different current ranges may be set. For example, a third current range (N1, N2), a second current range (N3, N4), a first current range (N5, ∞) may be set. Wherein N1< N2< N3< N4 < N5. Specifically, the current range in which the acquired current information falls is the target current range.
in the embodiment of the present invention, three leakage ranges may be set, which are the third leakage range (n1, n3), the second leakage range (n3, n5), and the first leakage range (n5, infinity). Wherein n1< n3< n 5. Different leakage ranges represent different leakage levels. Wherein (n1, n3) indicates slight leakage of the peripheral module, (n3, n5) indicates moderate leakage of the peripheral module, and (n5, infinity) indicates severe leakage of the peripheral module.
If the target current range corresponds to the third leakage range (n1, n3), it indicates that the peripheral module leaks electricity slightly; if the target current range corresponds to the second leakage range (n3, n5), the peripheral module is indicated to have moderate leakage; if the target current range corresponds to the first leakage range (n5, infinity), then it indicates a severe leakage of the peripheral module.
Specifically, the determined target current range falls within the range of which leakage range, and which leakage range is used as the target leakage range, so that 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 is determined to be the third leakage range (N1, N3), and the target current range corresponding to the target leakage range of the peripheral module is correspondingly determined.
It should be noted that step 202 and step 203 are substeps 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 within the interval 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 electric leakage range and the electric leakage protection operation is preset. When the electric leakage range is the third electric leakage range, the processor judges that the peripheral module is normally slightly leaked, and the electric leakage protection operation is as follows: the processor does not perform any action. When the electric leakage range is the second electric leakage range, the processor judges that the peripheral module has electric leakage of a larger degree, and then the electric leakage protection operation is as follows: the processor gives the user the option of controlling whether to turn off the peripheral module. When the electric leakage scope is first electric leakage scope, the treater judges that there is serious electric leakage in peripheral hardware module, may produce the potential safety hazard, then earth leakage protection operates: the processor forcibly turns off the peripheral module.
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 prompt that the power supply to the peripheral module is cut off.
Specifically, when the target current range is the 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 peripheral module has severe leakage, and in order to prevent the electronic device from generating severe heat or even a safety accident, after the power management module on the trunk line where the peripheral module is located is forcibly turned off, the display interface of the electronic device displays a prompt message informing the user that the peripheral module has been forcibly turned off.
Optionally, displaying an operation control in a display interface when 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 operation control;
and responding to the first input, controlling the power management module to continue to supply power to the peripheral module, or controlling the power management module to stop supplying power to the peripheral module.
Specifically, in the section where the target current range is the second current range (N3, N4) and the second current range (N3, N4) falls within the second leakage range (N3, N5), the second current range corresponds to the second leakage range. At this moment, when the processor judges that the external module has a large degree of electric leakage which is not possible to generate potential safety hazard, the display interface of the electronic equipment displays the operation control and the prompt information, 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 information 2: "the camera has a large degree of electric leakage, whether to turn it off", 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 located 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 the power management module again.
Optionally, in a case where the target current range is a third current range, and 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 only leaks electricity slightly normally, the influence on the whole device is not large, and the leakage protection operation is not required to be executed.
Optionally, the method further comprises: testing the reference leakage current of the peripheral module in advance 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 at the time of factory shipment. Therefore, when the peripheral module leaves the factory, a person skilled in the art can test the reference leakage current of the peripheral module in advance when the peripheral module is closed, and determine each leakage current range according to the reference leakage current. For example, if the reference leakage current test of a certain peripheral module is 5mA, the third leakage current range may be (5mA, 10mA), the second leakage current range may be (10mA, 15mA), and the first leakage current range may be (15mA, 20 mA).
The third leakage range (n1, n3) may be further subdivided into (n1, n2) and (n2, n 3). If the target leakage range corresponding to the target current range is (n1, n2), the peripheral module is normally leaked, and the processor does not need to operate; if the target leakage range corresponding to the target current range is (n2, n3), the peripheral module is slightly leaked, but the influence on the user is small, and the processor still does not need to operate. The second leakage range (n3, n5) may be further subdivided into (n3, n4) and (n4, n 5). If the target electric leakage range corresponding to the target current range is (n3, n4), the peripheral module is in a state of electric leakage to a certain degree, and the processor controls the display interface to display an operation control and normal prompt information which are selected by a user independently; if the target leakage range corresponding to the target current range is (n4, n5), the peripheral module leaks electricity to a greater extent, and the processor controls the display interface to display the operation control and the alarm prompt information, and the operation control and the alarm prompt information are selected by the user. Those skilled in the art can set different leakage ranges and leakage protection operations according to actual needs, and the present invention is not limited thereto, and all of them are within the protection range.
According to the embodiment of the invention, on the basis of the current structure, the processor can close the preset module for the preset time period, and in the preset time period, the detection module acquires the current information of the path where the power management module and the peripheral module are located, so as to determine whether the peripheral module leaks electricity according to the current information, and when the peripheral module leaks electricity, the leakage protection operation is performed according to the current information. Therefore, the effects that the electric leakage condition of the peripheral module can be detected, the corresponding electric leakage protection operation can be carried out according to the electric leakage condition, the service life of the peripheral module can be prolonged, and safety accidents are avoided are achieved.
