The following describes a specific way of determining the pumping state corresponding to the first sub-period of the target.
With continued reference to fig. 2, in some embodiments, determining the pumping state corresponding to the target first sub-period of the P first sub-periods based on the first pumping current value and the first current threshold may include:
q first pumping current values in a first target sub-period are obtained;
determining a second number of first pumping current values smaller than a first current threshold value in a first target subcycle;
under the condition that the second number is larger than a second preset value, determining that the target first sub-period is in an abnormal pumping state;
under the condition that the second number is not larger than a second preset value, determining that the target first sub-period is in a normal pumping state;
wherein Q is a positive integer.
In this embodiment, the target first sub-period may be any of the P first sub-periods.
For any first sub-period, respectively judging the magnitude of a first pumping current value and a first current threshold value acquired each time in the first sub-period, and when the first pumping current value is smaller than the first current threshold value, considering the equipment to be tested at the acquisition moment to be in an abnormal pumping state; and when the first pumping current value is not smaller than the first current threshold value, the equipment to be tested is considered to be in a normal pumping state at the acquisition moment.
The number of abnormal pumping states (i.e., the second number) in each first sub-period is obtained, and the second number is compared with a second preset value.
The second preset value is a user-defined value, and can be expressed in the form of number or ratio.
For example, when the second preset value is a ratio, and when the ratio of the second number to Q is greater than the second preset value, the device to be tested in the first sub-period is approximately considered to be an abnormal pumping state, and the state corresponding to the first sub-period is determined to be an abnormal pumping state; and under the condition that the ratio of the second quantity to the Q is not greater than a second preset value, the equipment to be tested is approximately considered to be normally loaded in the first sub-period, and the state corresponding to the first sub-period is determined to be the normally loaded state.
In some embodiments, determining a second number of target first sub-periods for which the first value of the current draw is less than the first current threshold may include: and under the condition that Q is not smaller than a second acquisition threshold value, determining a second quantity that the first pumping current value is smaller than the first current threshold value in the first target subcycle.
In this embodiment, the second acquisition threshold is a user-defined value, which is used to determine whether the number of the first pumping current values acquired in each first sub-period meets the preset acquisition number, so as to reduce the influence of random errors on the subsequent determination result.
According to the detection method of the charging equipment, provided by the embodiment of the application, the magnitude of the first pumping current value and the magnitude of the first current threshold value in the first sub-period of the target are compared, and the pumping state of the first sub-period of the target is further determined based on the magnitude relation between the second number of the first pumping current value smaller than the first current threshold value and the second preset value, so that the influence of sampling errors on a judgment result is effectively reduced, and the accuracy and precision of the detection result are improved.
Step 120, determining the type of the device to be tested based on the obtained second pumping current value and the second current threshold value of the device to be tested in the second period of the target under the condition that the pumping state corresponding to the first period of the target is the normal pumping state;
the type of the device to be tested comprises a non-wireless charging device and a wireless charging device, and the second current threshold value is larger than the first current threshold value.
In the step, the second pumping current value is a current value actually pumped by the device to be tested corresponding to the second period from the power supply device.
It should be noted that the second pumping current value and the first pumping current value may be the same value. That is, steps 110 and 120 may be performed sequentially or may be performed simultaneously, which is not limited by the present application.
The target second period may be any one of a plurality of second periods.
The second period may be the same period as the first period, and in the case that the second period is the same as the second period, the first pumping current value is the same as the second pumping current value, and step 110 and step 120 are performed synchronously.
It will be appreciated that each second cycle includes a plurality of second sub-cycles, each of which may include a plurality of pumping current acquisitions.
The second current threshold may be a value preset by a user, and is used for judging the magnitude of a current value pumped by the device to be tested, so as to further judge the type of the device to be tested based on the magnitude of the current value.
The type of the device to be tested comprises a non-wireless charging device or a wireless charging device.
The non-wireless charging equipment comprises intermittent charging equipment such as hand warmer, electric blanket and shoe dryer.
It can be understood that, in the case that the device to be tested is an intermittent charging device, the second pumping current value should be greater than the second current threshold under the normal pumping condition; under the condition that the device to be tested is a wireless charging device, the second pumping current value is not larger than the second current threshold value under the normal pumping condition.
In some embodiments, the target second period may include L second sub-periods including O second pumping current values, and the 2 nd to O second pumping current values in a previous second sub-period are 1 st to (O-1) th second pumping current values in a subsequent second sub-period adjacent to the previous second sub-period.
In this embodiment, L and O are both positive integers, and L > 1,O > 1.
Each second sub-period may include a plurality of current-carrying acquisitions.
As shown in FIG. 6, C4 1 、C4 2 、C4 3 … … and C4 NSET3+3 The same is the number of times of collection of the pumping current.
With continued reference to fig. 6, the l second sub-periods may include: C5C 5 1 、C5 2 And C5 3 A plurality of second sub-periods; wherein C5 1 Comprising C4 1 、C4 1 ……C4 NSET3 The value of O second pumping current is equal; C5C 5 2 Comprising C4 2 、C4 3 ……C4 NSET3+1 The value of O second pumping current is equal; C5C 5 3 Comprising C4 3 、C4 4 ……C4 NSET3+2 And (5) waiting for O second pumping current values.
The implementation of step 120 is described in detail below.
With continued reference to fig. 2, in some embodiments, the target second period may include L second sub-periods, and step 120 may include:
acquiring O second pumping current values in a second sub-period of the target;
determining a third number of second pumping current values greater than a second current threshold within a second sub-period of the target;
Under the condition that the third quantity is larger than a third preset value, determining that the equipment to be detected is non-wireless charging equipment;
wherein L and O are both positive integers.
In this embodiment, the target second sub-period may be any of the L second sub-periods.
In the application, the extraction current value of which the second extraction current value is larger than the second current threshold value can be approximately regarded as large current, and the extraction current value of which the second extraction current value is smaller than the second current threshold value can be approximately regarded as small current.
It can be understood that, in the practical application process, after the wireless charger is connected to the USB power supply device, the wireless charger intermittently sends a signal to detect whether a powered device such as a mobile phone or a bluetooth headset is connected. During the signal transmission period of the wireless charger, larger current is consumed; that is, after the wireless charger is connected to the USB port, the situation of pumping is similar to that of intermittent pumping USB equipment.
Fig. 7 illustrates three types of pump current patterns corresponding to the device under test, where ISET1 is a first current threshold and ISET2 is a second current threshold.
As can be seen from fig. 7, the pumping current corresponding to the non-intermittent pumping device is constant in the whole sampling period under the normal pumping state, and the value of the pumping current is larger (larger than the second current threshold ISET 2); the pumping current corresponding to the intermittent pumping equipment periodically changes in the whole sampling period, and the value of the corresponding pumping current is larger (larger than a second current threshold ISET 2) in a normal pumping state; the pumping current corresponding to the wireless charging equipment periodically changes in the whole sampling period, and in a normal pumping state, the value of the corresponding pumping current is smaller (larger than the first current threshold ISET1 and smaller than the second current threshold ISET 2).
For any second sub-period, respectively judging the magnitude of a second pumping current value and a second current threshold value acquired each time in the second sub-period, and when the second pumping current value is larger than the second current threshold value, considering the equipment to be tested at the acquisition moment as larger pumping current; and when the second pumping current value is not greater than the second current threshold value, the current pumped by the equipment to be tested at the collection moment is considered to be smaller.
And acquiring a larger number of times (namely a third quantity) of the pumping current in each second sub-period, and comparing the third quantity with a third preset value.
The third preset value is a user-defined numerical value, and the third preset value can be expressed as a number or as a ratio, which is not limited herein.
For example, for any second sub-period, when the third preset value is a ratio, and when the ratio of the third number to O is greater than the third preset value, it is approximately considered that the device to be tested normally pumps and the pumping current is greater in the second sub-period, so that the possibility that the device to be tested is a wireless charging device can be eliminated, and the device to be tested is determined to be a non-wireless charging device (i.e., an intermittent pumping device).
In some embodiments, determining a third amount by which the second pump current value is greater than the second current threshold value within the target second sub-period may include: and under the condition that O is not smaller than a third acquisition threshold value, determining a third quantity that the second pumping current value is larger than the second current threshold value in a second target subcycle.
In this embodiment, the third collection threshold is a user-defined value, which is used to determine whether the number of collected second pumping current values collected in each second sub-period meets the preset collection number, so as to reduce the influence of random errors on the subsequent determination result.
According to the detection method of the charging equipment, provided by the embodiment of the application, under the condition that the normal pumping of the equipment to be detected is determined, the magnitude relation between the second pumping current value and the second current threshold value in the second target sub-period is compared, and further under the condition that the pumping current is determined to be large, the equipment to be detected is determined to be the non-wireless charging equipment, so that the intermittent pumping equipment and the wireless charging equipment can be accurately distinguished, the identification precision and the judgment accuracy are higher, the detection method is suitable for the charging equipment of any type (wireless charging equipment, intermittent charging equipment and the like), and the detection method has wider application scenes and high universality.
The manner of determining the current information corresponding to the second sub-period of the target will be described below.
With continued reference to fig. 2, in some embodiments, after determining a third amount that the second pump current value is greater than the second current threshold value within the target second sub-period, the method may further include:
And under the condition that the third number is not larger than a third preset value, acquiring second pumping current values in one sub-period after the target second sub-period in the L second sub-periods.
In this embodiment, for example, in the case that the third preset value is a ratio, when the ratio of the third number to O is not greater than the third preset value, it is approximately considered that the pumping current corresponding to the device to be tested in the second sub-period is smaller, and at this time, the device to be tested cannot be excluded as the wireless charging device, then the next second sub-period is repeated to perform the above steps for determining.
The second pumping current value included in the next second sub-period may be other second pumping current values except the earliest second pumping current value collected at one time in the current second sub-period, and the second pumping current value collected at the next time.
According to the detection method of the charging equipment, provided by the embodiment of the application, the influence of sampling errors on the judgment result can be effectively reduced by repeatedly judging the magnitudes of the second pumping currents corresponding to the plurality of second sub-periods under the condition that the pumping currents are smaller, so that the accuracy and precision of the detection result are improved.

And under the condition that the current state is determined to be the normal pumping state or the condition that the equipment to be tested is determined to be the intermittent pumping equipment, controlling the power supply equipment to start power supply so as to normally supply power.
According to the detection method of the charging equipment provided by the embodiment of the application, the first pumping current value and the first current threshold value in the first period of the target are used for determining the pumping state corresponding to the first period of the target, and the second pumping current value and the second current threshold value in the second period of the target are used for determining the type of equipment to be detected, so that misjudgment caused by pumping detection on the intermittent charging equipment in the period of stopping pumping in the intermittent pumping period can be reduced, the accuracy of the pumping state judgment result is obviously improved, in addition, the intermittent charging equipment and the wireless charging equipment can be accurately distinguished, the judgment accuracy is high, the method is suitable for charging equipment of any type (wireless charging equipment, intermittent charging equipment, non-intermittent charging equipment and the like), and the method has wider application scenes and high universality.
In actual implementation, the above-described steps 110 and 120 of the present application may be implemented by the detection means of the charging device as shown in fig. 8 and 9. The detection device of the charging device can be arranged on the power supply device.
As shown in fig. 8, the apparatus may include a power supply module, an identification control module, and a current detection module.
Wherein, as shown in fig. 9, the power supply module includes a power supply and a pass-through tube Q1.
The channel Q1 is directly connected to the power supply and the USB load, and serves to control whether the power supply supplies the USB load.
The current detection module includes an amplifier AMP1, a comparator CMP2, a reference voltage VREF1, and a reference voltage VREF2.
The current detection module is used for detecting the voltage drop of the channel tube Q1, and sending the comparison result to the identification control module after amplification and comparison.
The identification control module detects the current extracted by the USB load by controlling the current detection module and compares the current with different reference voltages to obtain a corresponding result, and then controls the on and off of the channel tube Q1 according to the detection result to control whether the power supply supplies to the USB load.
The implementation of the present application will be specifically described with reference to fig. 3, 8 and 9.
Step 401, detecting that the USB device is accessed, or opening the USB port by other means, then step 402 is entered.
Step 402, detecting that the port is open and enabling no-load detection, and then step 403 is entered.
In step 403, the voltage drop of the pass transistor Q1 is amplified by AMP1 and compared with VREF1 (i.e., the first current threshold) by CMP1, to obtain a first comparison result C1, and the process proceeds to step 404.
In step 404, a determination is made as to whether the first comparison result C1 is high.
The first comparison result C1 is high, which indicates that the first pumping current of the USB equipment detected at the time is lower than a first current threshold represented by VREF 1; step 405 is entered.
The first comparison result C1 is low, which indicates that the first pumping current of the USB equipment detected at the time is higher than a first current threshold represented by VREF 1; step 405 is entered.
In step 405, the counters M1 and N1 are operated according to the result of the first comparison result C1.
If the first comparison result C1 is high, the counter M1 is controlled to be increased by 1, and the counter N1 is controlled to be increased by 1; step 406 is entered.
If the first comparison result C1 is low, the counter M1 is controlled to be unchanged, and the counter N1 is increased by 1; step 406 is entered.
Wherein the counter M1 is used for counting the number of times the first comparison result C1 is high (i.e., the second number above), and the counter N1 is used for counting the total number of times the first comparison result C1 is high (i.e., the Q above).
In step 406, it is determined whether the value of the counter N1 (i.e. Q) is equal to the preset detection number NSET1 (i.e. the second acquisition threshold).
If so, then the first sub-period is deemed to have collected enough data and step 407 is entered.
If not, it is considered that enough data is not acquired in the first sub-period, and data needs to be acquired again, and step 403 is performed to continue to acquire the first pumping current.
Step 407, comparing the value (i.e. the second number) of the counter M1 with a preset count value MSET1 (i.e. a second preset value) to obtain a second comparison result C2, and clearing the count values of M1 and N1 after obtaining C2; step 408 is entered.
The second preset value is smaller than or equal to a second acquisition threshold value.
In step 408, a determination is made as to whether the second comparison result C2 is high.
If the second comparison result C2 is high, the USB device is considered to be fully charged or the USB device is extracted in the second comparison result C2 acquisition period (i.e., the first sub-period), i.e., no load is detected; step 409 is entered.
If the second comparison result C2 is low, the USB equipment is considered to be normally in the second comparison result C2 acquisition period (namely the first sub-period); step 409 is entered.
Step 409, according to the determination result of the second comparison result C2, the counters M2 and N2 are operated.
If the second comparison result C2 is high, the counter M2 is controlled to be increased by 1, and the counter N2 is controlled to be increased by 1; step 410 is entered.
If the second comparison result C2 is low, the counter M2 is unchanged, and the counter N2 is increased by 1; step 410 is entered.
The counter M2 is used for counting the number of times the second comparison result C2 is high (i.e., the first number), and the counter N2 is used for counting the total number of times the second comparison result C2 is high (i.e., P).
In step 410, it is determined whether the value of the counter N2 (i.e., P) is equal to the preset detection count NSET2 (i.e., the first acquisition threshold).
If so, the large period (i.e., the first period) is considered to have enough data collected, and step 411 is entered.
If not, it is indicated that the large period (i.e., the first period) does not collect enough data, and the data needs to be collected again, and the process proceeds to step 403.
Step 411, comparing the value (i.e. the first number) of the counter M2 with a preset count value MSET2 (i.e. a first preset value) to obtain a third comparison result C3; step 412 is entered.
The first preset value is smaller than or equal to a first acquisition threshold value.
In step 412, a determination is made as to whether the third comparison result C3 is high.
If the third comparison result C3 is high, it is considered that the USB device is fully charged or the USB device is unplugged in the third comparison result C3 acquisition period (i.e., the first period), i.e., no load is detected, and the process proceeds to step 413.
If the third comparison result C3 is low, the USB device is considered to be normally booted in the third comparison result C3 acquisition cycle (i.e. the first cycle), and step 414 is entered.
In step 413, the third comparison result C3 is high, which indicates that the USB device is fully charged or the USB device is pulled out in the third comparison result C3 acquisition period, the USB port is in an idle state, the identification detection module closes the channel Q1 and clears the counters M1, M2, M3, N1, N2 and N3, and finally closes the idle detection, and the idle detection flow ends.
Step 414, the third comparison result C3 is low, which indicates that the USB device in the third comparison result C3 acquisition period is normally booted, the second comparison result C2 with the earliest time in the third comparison result C3 acquisition period is removed, and the rest of the second comparison results C2 enter the next third comparison result C3 acquisition period (i.e., enter the next first period); step 415 is entered.
Step 415, determining whether the removed second comparison result C2 is high; step 416 is entered.
Step 416, if the removed second comparison result C2 is high, the counter M2 is controlled to decrease by 1, and the counter N2 is controlled to decrease by 1; step 403 is entered.
If the removed second comparison result C2 is low, the counter M2 is controlled to be unchanged, and the counter N2 is decremented by 1; step 403 is entered.
Step 417, the voltage drop of the channel Q1 is amplified by AMP1 and compared with VREF2 (i.e., the second current threshold) by CMP2, to obtain a fourth comparison result C4; step 418 is entered.
In step 418, a determination is made as to whether the fourth comparison result C4 is high.
If the fourth comparison result C4 is high, the second pumping current of the detected USB device is higher than the set current represented by VREF2 (i.e., the second current threshold); step 419 is entered.
If the first comparison result C1 is low, the second pumping current of the detected USB device is lower than the set current represented by VREF2 (i.e., the second current threshold); step 419 is entered.
In step 419, the counters M3 and N3 are operated according to the result of the fourth comparison result C4.
If the fourth comparison result C4 is high, the counter M3 is controlled to be increased by 1, and the counter N3 is controlled to be increased by 1; step 420 is entered.
If the fourth comparison result C4 is low, the counter M3 is controlled to be unchanged, and the counter N3 is increased by 1; step 420 is entered.
The counter M3 is used for counting the number of times the fourth comparison result C4 is high (i.e., the third number), and the counter N3 is used for counting the total number of times the fourth comparison result C4 is high (i.e., O).
In step 420, it is determined whether the value of the counter N3 (i.e. O) is equal to the preset detection number NSET3 (the third acquisition threshold).
If the data are equal, the fourth comparison result C4 is considered to have acquired enough data in the acquisition period (i.e., the second sub-period), and the process proceeds to step 421.
If not, it is assumed that the fourth comparison result C4 does not acquire enough data in the acquisition period (i.e., the second sub-period), and the data needs to be acquired again, and the process proceeds to step 417.
Step 421, comparing the value of the counter M3 (i.e. the third number) with the preset count value MSET3 (i.e. the third preset value) to obtain a fifth comparison result C5; step 422 is entered.
The third preset value is smaller than or equal to a third acquisition threshold value.
In step 422, a determination is made as to whether the fifth comparison result C5 is high.
If the fifth comparison result C5 is high, it is considered that the USB device is normally loaded and the current drawn by the USB device is larger in the fifth comparison result C5 acquisition period (i.e., the second sub-period), so that the wireless charger can be eliminated, and step 423 is entered.
If the fifth comparison result C5 is low, it is considered that the USB device in the fifth comparison result C5 acquisition period (i.e. the second sub-period) has a smaller current, and the wireless charger cannot be excluded, and the process proceeds to step 424.
Step 423, if the fifth comparison result C5 is high, the USB device is considered to be normally loaded and the current drawn by the USB device is larger in the fifth comparison result C5 acquisition period (i.e., the second sub-period), so that the wireless charger can be eliminated; resetting M1, M2, M3, N1, N2 and N3, and resetting the no-load detection; step 417 is entered.
Step 424, if the fifth comparison result C5 is low, the USB device in the fifth comparison result C5 acquisition period (i.e. the second sub-period) is considered to have a smaller current, which cannot exclude the wireless charger; removing the fourth comparison result C4 with the earliest time in the fifth comparison result C5 acquisition period, and entering the next fifth comparison result C5 acquisition period (i.e. entering the next second sub-period) by the rest of the fourth comparison results C4; step 425 is entered.
Step 425, determining whether the removed fourth comparison result C4 is high; step 426 is entered.
Step 426, if the removed fourth comparison result C4 is high, the counter M3 is controlled to be decremented by 1, and the counter N3 is controlled to be decremented by 1; step 417 is entered.
If the removed fourth comparison result C4 is low, the counter M3 is controlled to be unchanged, and the counter N3 is decremented by 1; step 417 is entered.
Wherein step 403 and steps below are performed in parallel with step 417 and steps below.
The identification control module controls whether the power supply module stops supplying power or not based on the judging result.
