[0038] The present invention will be described in further detail below with reference to the accompanying drawings and embodiments.

[0039] The embodiment of the present invention provides a method for detecting the battery status of a door lock. Figure 1 As shown, the method includes:

[0040] Step 101: Detect the battery status of the door lock, and determine whether the door lock is powered by a mixture of new and old batteries according to the battery status;

[0041] Step 102: When it is determined that the door lock is powered by a mixture of new and old batteries, the user is prompted to replace the batteries.

[0042] The method of this embodiment can be applied to a smart door lock. When the door lock applies the method of this embodiment, the door lock can actively discover whether it is powered by a mixture of new and old batteries. When it is powered by a mixture of new and old batteries, it can send a reminder to the user to help the user distinguish between the mixed use of new and old batteries, thereby reducing the probability of the door lock being powered by a mixture of new and old batteries, resulting in excessive power consumption, and improving the user experience.

[0043] In actual application, when the smart door lock detects that new and old batteries are mixed, the user can be prompted to replace the batteries through the application on the terminal.

[0044] In one embodiment, detecting the battery status of the door lock and determining whether the door lock is powered by a mixture of new and old batteries according to the battery status includes:

[0045] Detect the voltage value at both ends of each battery of the door lock; and determine whether the door lock is powered by a mixture of new and old batteries based on the voltage value at both ends of each battery.

[0046] In actual applications, smart door locks are usually powered by multiple batteries connected in series. When new and old batteries are connected in series and mixed for power supply, the voltage of the old battery is lower than that of the new battery. Therefore, by embedding the corresponding voltage detection circuit to detect each battery, it can be determined whether the smart door lock is in a state of mixed power supply of new and old batteries.

[0047] In one embodiment, the voltage value across each battery of the door lock is detected, including:

[0048] A voltage detection circuit is used to detect the voltage value at both ends of each battery of the door lock; wherein, the voltage detection circuit includes a first resistor and a second resistor, one end of the first resistor is connected to one end of each corresponding battery, the other end of the first resistor is connected to the voltage sampling chip, and the other end of the first resistor is also grounded through the second resistor.

[0049] In actual application, the circuit can be led out from the shrapnel at the two ends of each battery in the battery box of the smart door lock, and a megaohm sampling resistor can be connected between the circuits. After the voltage of each node is divided, it is connected to the analog IO port of the chip, and the voltage of each node is collected using the AD conversion function. That is, the voltage is sampled between the batteries through a megaohm resistor, and the corresponding node is connected to the analog IO port of the processor. The operating voltage of each node can be calculated, and whether new and old batteries are mixed can be detected.

[0050] In one embodiment, when the number of the batteries is four, judging whether the door lock is powered by a mixture of new and old batteries according to the voltage value at both ends of each battery includes:

[0051] Obtaining a first difference between the voltage values ​​at both ends of the four connected batteries and twice the voltage values ​​at both ends of the third and fourth batteries;

[0052] Determining whether the first difference is less than or equal to a preset first threshold;

[0053] When the first difference is less than or equal to a preset first threshold, obtaining a second difference between the voltage values ​​across the third and fourth battery cells and twice the voltage value across the fourth battery cell;

[0054] Determining whether the second difference is less than or equal to a preset second threshold;

[0055] When the second difference is less than or equal to a preset second threshold, obtaining a third difference between the voltage value at both ends of the first battery and the voltage value at both ends of the second battery;

[0056] Determining whether the third difference is less than or equal to a preset third threshold;

[0057] When the third difference is less than or equal to a preset third threshold, it is determined that the door lock is not powered by a mixture of new and old batteries.

[0058] Correspondingly, when the first difference is greater than a preset first threshold, it is determined that the door lock is powered by a mixture of new and old batteries. When the second difference is greater than a preset second threshold, it is determined that the third battery and the fourth battery are in different states of age. When the third difference is greater than a preset third threshold, it is determined that the first battery and the second battery are in different states of age.

[0059] Below, based on Figure 2 The circuit connection relationship in the figure is described in detail to determine whether new and old batteries can be mixed.

[0060] See also Figure 2 , Figure 2It includes 4 batteries V1, V2, V3 and V4 connected in series. Voltage detection circuits are connected to one end of battery V1, the connection between batteries V1 and V2, the connection between batteries V2 and V3, and the connection between batteries V3 and V4 respectively. Each voltage detection circuit includes a first resistor (R1, R3, R5 and R7 in the figure, all with a resistance value of 1MΩ) and a second resistor (R2, R4, R6 and R8 in the figure, all with a resistance value of 1MΩ), one end of the first resistor is connected to one end of each corresponding battery (one end of battery V1, the connection between batteries V1 and V2, the connection between batteries V2 and V3, and the connection between batteries V3 and V4), the other end of the first resistor is connected to the voltage sampling chip, and the other end of the first resistor is also grounded through the second resistor.

[0061] Based on the above connection relationship, when judging, first, compare the voltage relationship between the AC nodes. If the result is within the specified range, then detect the voltage relationship between the CD nodes. If the result is within the specified range, compare the voltage difference between the AB nodes and the BC nodes. If the result is within the range, it is determined to be a normal state, that is, there is no mixing of new and old batteries. If any of the above three comparisons exceeds the specified range, it can be determined that new and old batteries are mixed. Through the above steps, it can be determined whether the smart door lock is powered by a mixture of new and old batteries.

[0062] When it is detected that the smart door lock is in a state of mixed power supply of new and old batteries, the application can prompt the user to inform the user that the smart door lock is in a state of mixed power supply of new and old batteries, explain the hazards of mixing new and old batteries, and recommend that the user replace the battery as soon as possible.

[0063] Specifically, see Figure 3 , the previous process can be:

[0064] The battery box leads out wires to the circuit board at the connection between every two batteries, and leads out two 1MΩ resistors to ground between the batteries for voltage sampling.

[0065] Step 301: The detection circuit extracts the voltage value of each battery after voltage division;

[0066] Step 302: determine whether |VA-2VC|>VN1;

[0067] If yes, go to step 305, if no, go to step 303;

[0068] Step 303: determine whether |VC-2VD|>VN2;

[0069] If yes, go to step 305, if no, go to step 304;

[0070] Step 304: determine whether |VAB-VBC|>VN3;

[0071] If yes, go to step 305, if no, go to step 306;

[0072] Step 305: Sending a reminder to the user to mix old and new batteries through the application;

[0073] Step 306: End.

[0074] Specifically, in this embodiment, the voltage relationship between the AC nodes is first compared. In an ideal state, when the new and old batteries are not mixed, the voltage at A is twice the voltage at C. When the new and old batteries are mixed, if one battery is different from the other three, it is detected that the voltage at A is not twice the voltage at C; if two batteries are different from the other two, when V1 and V2 are the same, and V3 and V4 are the same, it is detected that the voltage at A is not twice the voltage at C. The actual situation includes differences in the batteries themselves and sampling errors, so the preset abnormal value VN1 is used for comparison with |VA-2VC|.

[0075] When the voltage relationship of the AC node meets the requirements, the voltage relationship between the CD nodes is compared. Ideally, when the old and new batteries are not mixed, the voltage at C is twice the voltage at D. When the old and new batteries of V3 and V4 are mixed, it is detected that the voltage at C is not twice the voltage at D. The actual situation includes the differences between the batteries themselves and the sampling error, so the preset abnormal value VN2 is used for comparison with |VC-2VD|.

[0076] When the voltage relationship of the CD node meets the requirements, the voltage relationship of batteries V1 and V2 is compared. Ideally, when the old and new batteries are not mixed, the voltage of V1 (the voltage difference of the AB nodes) is equal to the voltage of V2 (the voltage difference of the BC node). When the old and new batteries of V1 and V2 are mixed, it is detected that the voltage of V1 (the voltage difference of the AB nodes) is not equal to the voltage of V2 (the voltage difference of the BC node). The actual situation includes the differences between the batteries themselves and the sampling error, so the preset abnormal value VN3 is used to compare with the voltage difference of the two batteries |VAB-VBC|.

[0077] Further, see Table 1 below, which shows several situations in which new and old batteries are mixed.
