The singular terms "one" and "the" may also include plural forms.

[0037] Here we first explain some terms involved in the present invention.

[0038] The voltage AD value is the voltage digital signal (Analog To Digital, AD) value, which is converted by an analog to digital converter (Analog To Digital Converter, ADC) to obtain the corresponding digital signal value.

[0039] See attached Figure 1 , Figure 1 FIG. 1 is a flow chart showing the main steps of a vehicle battery monitoring method according to an embodiment of the present invention. Figure 1 As shown, the vehicle battery monitoring method in the embodiment of the present invention mainly includes the following steps 101 to 104.

[0040] Step 101, obtaining the current voltage AD value of the vehicle-mounted equipment;

[0041] In a specific implementation process, a voltage monitoring device may be used to obtain a current voltage AD value of the vehicle-mounted device.

[0042] Step 102: determining a target voltage range associated with the current voltage AD value based on a correlation relationship between a preset voltage AD value range and a voltage range;

[0043] Among them, each voltage range corresponds to a different voltage calculation formula;

[0044] In a specific implementation process, the association relationship between different voltage ranges and different voltage AD value ranges can be established in advance, and each voltage range corresponds to a different voltage calculation formula. In this way, after obtaining the current voltage AD value of the vehicle-mounted device, the target voltage range associated with the current voltage AD value can be determined based on the association relationship between the preset voltage AD value range and the voltage range, and then the voltage calculation formula corresponding to the target voltage range can be obtained.

[0045] In a specific implementation process, high voltage and low voltage cause different currents under the same load power, so that the actual voltage division value of the power line and NTC components before the voltage monitoring device access point (hereinafter referred to as the detection point) is not a fixed value. Therefore, the voltage calculation formula corresponding to different voltage ranges can be:

[0046] V=a i *(AD±x i );

[0047] Wherein, V represents the detection point voltage, a i represents the voltage coefficient corresponding to the i-th voltage range, the AD represents the current voltage AD value of the vehicle-mounted device, and the xi represents the compensation difference between the AD difference in the i-th voltage range and the AD difference in the reference voltage range, wherein the x i It indicates that the AD difference within the i-th voltage range is the difference between the voltage AD value of the vehicle-mounted device in the standby state and the voltage AD value in the power-on state at the same voltage within the i-th voltage range; the AD difference of the reference voltage range is the difference between the voltage AD value of the vehicle-mounted device in the standby state and the voltage AD value in the power-on state at the same voltage within the j-th voltage range.

[0048] In a specific implementation process, the a i It is the ratio between the actual voltage of the sample battery and the AD value of the sample voltage in the standby state.

[0049] Specifically, different voltages can be preset, and different voltage AD values ​​of the vehicle-mounted equipment in the standby state are counted as sample voltage AD values ​​in the standby state. The actual voltage of the sample battery of the vehicle battery is measured using a multimeter, and the ratio between the actual voltage of the sample battery and the sample voltage AD value in the standby state is used as the voltage coefficient a. i In this way, in the later process of obtaining the actual voltage of the battery, the voltage coefficient a is calculated relative to the sample voltage AD value when the vehicle-mounted device is turned on. i The process of obtaining the actual voltage of the battery is simpler and may not be affected by the actual operating conditions of the vehicle-mounted equipment when it is turned on.

[0050] In a specific implementation process, for a parking air conditioner, the sample voltage AD value in the on state is usually the voltage AD value under a fixed wind speed. When the parking air conditioner is in the on state, the actual wind speed may be greater than the fixed wind speed or less than the fixed wind speed, which may ultimately affect subsequent calculations.

[0051] For example, the voltage coefficient a is calculated using the sample voltage AD value in the parking air conditioner standby state. i The voltage coefficient a is calculated by using the sample voltage AD value when the parking air conditioner is turned on. i In this way, if the actual wind speed of the parking air conditioner is lower than the fixed wind speed, a compensation voltage needs to be subtracted after the voltage at the detection point is obtained according to the voltage calculation formula. If the actual wind speed of the parking air conditioner is higher than the fixed wind speed, a compensation voltage needs to be added after the voltage at the detection point is obtained according to the voltage calculation formula. The voltage coefficient a is calculated by using the sample voltage AD value in the standby state of the parking air conditioner. i After calculating the voltage at the detection point, a compensation voltage is added regardless of whether the actual wind speed of the parking air conditioner is higher or lower than the fixed wind speed when the parking air conditioner is turned on.

[0052] Step 103, substituting the current voltage AD value into the voltage calculation formula corresponding to the target voltage range to obtain the detection point voltage of the vehicle battery;

[0053] Step 104: Determine the actual voltage of the battery according to the operating status of the vehicle-mounted equipment and the voltage at the detection point.

[0054] In a specific implementation process, after the vehicle-mounted device is turned on, it is equivalent to connecting to a load increase, which will increase the bus current. There is a voltage drop caused by the power line and the NTC component voltage division between the vehicle battery output and the detection point. This voltage drop cannot be ignored after the startup power is increased, so the preset compensation voltage is increased according to the different startup operating powers. Therefore, if the operating state of the vehicle-mounted device is the startup state, the detection point voltage is added to the preset compensation voltage to obtain the actual voltage of the battery. After the vehicle-mounted device is turned off, it is equivalent to not connecting to the load, the bus current is small, and the voltage drop caused by the power line and NTC components before the detection point can be ignored. Therefore, if the operating state of the vehicle-mounted device is the standby state, the detection point voltage is used as the actual voltage of the battery.

[0055] The vehicle battery monitoring method of the present embodiment obtains the current voltage AD value of the vehicle-mounted device, determines the target voltage range associated with the current voltage AD value based on the correlation relationship between the preset voltage AD value range and the voltage range, substitutes the current voltage AD value into the voltage calculation formula corresponding to the target voltage range, obtains the detection point voltage of the vehicle-mounted battery, and determines the actual voltage of the battery according to the operating status of the vehicle-mounted device and the detection point voltage, thereby achieving accurate and reliable acquisition of the vehicle battery voltage, and further effectively monitoring the performance of the vehicle battery, preventing the vehicle battery from being exhausted and reducing the service life of the vehicle battery.

[0056] It should be pointed out that although the various steps in the above embodiments are described in a specific order, those skilled in the art can understand that in order to achieve the effects of the present invention, different steps do not have to be performed in such an order. They can be performed simultaneously (in parallel) or in other orders. These changes are within the scope of protection of the present invention.

[0057] Furthermore, the present invention also provides a control device for a smart home device.

Figure 2 As shown, the vehicle battery monitoring device according to the embodiment of the present invention may include an acquisition module 20 , a first determination module 21 , a calculation module 22 and a second determination module 23 .

[0059] An acquisition module 20 is used to acquire a current voltage AD value for the vehicle-mounted device;

[0060] A first determination module 21 is used to determine a target voltage range associated with the current voltage AD value based on a correlation relationship between a preset voltage AD value range and a voltage range; wherein each voltage range corresponds to a different voltage calculation formula;

[0061] The voltage calculation formula is:

[0062] V=a i *(AD±x i );

[0063] Wherein, V represents the detection point voltage, a i represents the voltage coefficient corresponding to the i-th voltage range, the AD represents the current voltage AD value of the vehicle-mounted device, and the x i represents the compensation difference between the AD difference in the i-th voltage range and the AD difference in the reference voltage range, wherein the x i It indicates that the AD difference within the i-th voltage range is the difference between the voltage AD value of the vehicle-mounted device in the standby state and the voltage AD value in the power-on state at the same voltage within the i-th voltage range; the AD difference of the reference voltage range is the difference between the voltage AD value of the vehicle-mounted device in the standby state and the voltage AD value in the power-on state at the same voltage within the j-th voltage range.

[0065] A calculation module 22, used for substituting the current voltage AD value into the voltage calculation formula corresponding to the target voltage range to obtain the detection point voltage of the vehicle battery;

[0066] The second determination module 23 is used to determine the actual voltage of the battery according to the operating state of the vehicle-mounted equipment and the voltage at the detection point.

[0067] In a specific implementation process, if the operating state of the vehicle-mounted device is standby state, the detection point voltage is used as the actual voltage of the battery; if the operating state of the vehicle-mounted device is on state, the detection point voltage is added to the preset compensation voltage to obtain the actual voltage of the battery.
