The smart home becomes a new consumption trend, and as an important part of the smart home, taking the smart lock as an example, the smart lock is an entrance of the smart home, and the importance is self-evident. Along with people's attention to gate safety, the intelligence lock of taking the video module begins to popularize and becomes the mainstream gradually, and the intelligence lock of taking the video module can not only defend illegal invasion, can also carry out real time monitoring and early warning to the gate condition.

For electronic equipment including security equipment (intelligent lock) and camera equipment (video module), low power consumption and long endurance are always the rigid requirements of users. The electronic equipment is added with a camera monitoring function with high power consumption on the basis of the original security equipment. There are a number of current power supply schemes for electronic devices.

In the power supply scheme commonly used, adopt a power to supply power for security protection equipment and the camera equipment in the electronic equipment simultaneously, for example use No. 5 dry battery or lithium cell to intelligent lock and video module power supply simultaneously. Although the same power supply scheme is simplest and lowest in cost, the following disadvantages are brought about: firstly, camera equipment belongs to the functional module of big consumption heavy current like the video module, must produce great influence to security protection equipment's stand-by time with security protection equipment sharing a power, and, security protection equipment and camera equipment required supply voltage are different, for example the intelligent lock power supply needs supply voltage to be 4.8V ~ 6V, and the video module needs supply voltage to be 3.5 ~ 4.35V, consequently must do the buck-boost to the power to one of them module when adopting same power supply to supply power, can influence the discharge efficiency of power like this, shorten the length of time of use of power.

Therefore, in order to avoid the above drawback, improve and carry out independent power supply for adopting two power respectively to security protection equipment and camera equipment, for example use No. 5 dry battery and lithium cell to supply power for the part of intelligent lock and the part of video module respectively. The lithium battery adopts a detachable charging mode, and the lithium battery can adopt a charging IC to perform charging control on the battery core.

However, when the inventor of the present application tests and uses the power supply scheme, it is found that: although the video monitoring function is prevented from influencing the standby time of the electronic equipment by the aid of the mode for independently supplying power to the security equipment and the camera equipment, the power supplies of the two modules are relatively independent, the two modules are not distinguished primarily and secondarily, unified management can not be performed on system functions, and the power supplies of the two modules are relatively independent, so that the service condition of the camera equipment such as a lithium battery of a video module can not be monitored on the electronic equipment, and accurate detection and calibration of an electric quantity curve can not be performed on the electric quantity of the lithium battery.

Therefore, the inventor of the present application proposes a brand new hardware frame of an electronic device, which adopts different power supplies for security equipment and image capturing equipment in the electronic device, and designs the power supply of the image capturing equipment in particular, so that the security equipment can control the power supply of the image capturing equipment. For example, the inventor of this application realizes brand-new hardware design frame to the intelligence lock, adopt the mode that the part power supply of double cell for intelligence lock and video module respectively, the influence of the function of having avoided increasing video monitoring to the intelligence lock consumption, special design has been done to the lithium cell of video module simultaneously, the global design frame uses the intelligence lock function as leading, the function of video module is the mode of assisting, accord with the characteristics of intelligence lock function primary, intelligence lock part can realize using the lithium cell to monitor video monitoring simultaneously, and unified management, the electric quantity that also can guarantee the electric quantity monitoring of lithium cell can be more accurate and the electric quantity of the most efficient utilization lithium cell.

Fig. 1 is a schematic structural diagram of an embodiment of an electronic device according to the present disclosure, where the electronic device may be an intelligent security device, and the intelligent security device may be used in multiple security protection scenarios. Such as smart locks provided on doors, smart doors, safe deposit boxes, smart screens, etc. The technical scheme in the embodiment is mainly used for realizing power supply control of the electronic equipment.

Specifically, the electronic device in this embodiment may include the following structure:

a security device 1 and an image pickup device 2.

The security device 1 at least forms a first power supply path a with the first power supply 3, and the first power supply 3 supplies power to the security device 1 when the first power supply path a is conducted. For example, the dry battery is configured on the intelligent lock, the dry battery and the intelligent lock form a main power supply path, and under the condition that the main power supply path is conducted, if the intelligent lock opens the door lock function and is started, the dry battery supplies power to the intelligent lock through the conducted main power supply path.

And the image pickup apparatus 2 forms a second power supply path b with at least the power supply switch 4 and the second power supply 5. The second power supply 5 supplies power to the image pickup apparatus with the second power supply path a turned on. For example, a switch and a lithium battery which can be controlled by the intelligent lock are configured for a video module in the intelligent lock, the lithium battery, the video module and the switch form a slave power supply path, and under the condition that the slave power supply path is conducted, if the intelligent lock starts a video monitoring function, the lithium battery supplies power to the video module through the conducted slave power supply path.

The security device 1 is connected with the power supply switch 4, so that the security device 1 controls the power supply switch 4 to be in a disconnected state or a connected state;

specifically, when the power supply switch 4 is in the connected state, the second power supply path b is in the on state, and when the power supply switch 4 is in the off state, the second power supply path b is in the off state.

For example, as shown in fig. 2, the smart lock is connected to a switch on the slave power supply path, and the smart lock controls the on/off of the slave power supply path by controlling the on/off of the switch. For example, when the intelligent lock control switch is turned off, the slave power supply path is in a power supply cut-off state, and at this time, the lithium battery stops supplying power to the video module; under the condition that intelligence lock control switch switched on, be in the state that the power supply switched on from the power supply route, at this moment, the lithium cell can supply power to the video module, and the video module can carry out the collection of multimedia data like video etc..

In specific implementation, a channel capable of transmitting a control instruction can be established between the security device 1 and the power supply switch 4, so that the security device 1 transmits the control instruction to the power supply switch 4, and the power supply switch 4 is in a disconnected state or a connected state according to the control instruction.

According to the scheme, in the electronic equipment provided by the embodiment of the application, the security equipment and the camera equipment in the electronic equipment are respectively powered by independent power supplies, meanwhile, the security equipment is connected to the power supply switch on the power supply path where the camera equipment is located, the security equipment can carry out power supply control on the power supply of the camera equipment, and therefore master-slave control is achieved on the two parts in the electronic equipment.

In one implementation, the security device 1 may control the power switch 4 to be in the off state under any one or more of the following conditions:

in the first case: the remaining capacity of the second power supply 5 is less than or equal to a first threshold, the first threshold is a preset value, and the first threshold can be factory-set according to actual product requirements, or can be customized and modified by a user according to requirements. Under the condition that the residual capacity of the second power supply 5 is less than or equal to the first threshold value, the security device 1 controls the power supply switch 4 to be in the off state, the second power supply path b is in the cut-off state, the second power supply 5 does not supply power to the image pickup device 2 any more, and at this time, the image pickup device 2 is turned off. Based on this, under the condition that the second power supply 5 is charged and the residual current of the second power supply 5 is greater than the first threshold value, the security device 1 can control the power supply switch 4 to be in a connection state, the second power supply path b is in a conduction state, the second power supply 5 can continue to supply power to the camera device 2, and the camera device 2 can continue to acquire multimedia data under the power supply of the second power supply 5 after the camera device 2 is started.

For example, under the condition that the residual capacity of lithium cell is less than 5%, the switch disconnection on the intelligent lock control follow power supply route on the main power supply route, make the lithium cell on the follow power supply route no longer supply power to the video module, the video monitoring function on the intelligent lock is closed this moment, after the lithium cell is charged, the residual capacity is higher than 5% if be full of under the condition after, the switch connection on the intelligent lock control follow power supply route on the main power supply route, make the lithium cell on the follow power supply route resume and supply power to the video module, the video monitoring function on the intelligent lock can be resumeed this moment, carry out video acquisition.

In the second case, there is a short circuit in the second power supply path b. The short circuit is a case where the positive and negative poles of the second power supply 5 are directly connected due to a bypass of a circuit element in the second power supply path b or the like. Under the condition that the second power supply path b has a short circuit, in order to ensure the safety of the image pickup device 2 and the security device 1, the security device 1 controls the power supply switch 4 to be in an off state, the second power supply path b no longer has a short circuit, and the second power supply 5 no longer supplies power to the image pickup device. Based on this, after the circuit fault in the second power supply path b is detected and adjusted so that the short circuit in the second power supply path b is eliminated, the security device 1 may control the power supply switch 4 to be in a connection state, the second power supply path b is in a conduction state, the second power supply 5 may continue to supply power to the image pickup device 2, and the image pickup device 2 may continue to acquire multimedia data under the power supply of the second power supply 5 after the image pickup device 2 is turned on.

For example, when the lithium cell appears the short circuit from the power supply route, the power supply risk may exist, if the condition such as lithium cell is overheated or burns out, the switch disconnection on the intelligent lock control follow power supply route on the main power supply route this moment, make from power supply route in the off-state, the lithium cell is no longer to the video module power supply, the unable normal use of video monitoring function on the intelligent lock this moment, after the short circuit risk of lithium cell was got rid of, the switch connection on the intelligent lock control follow power supply route on the main power supply route, make from the lithium cell recovery on the power supply route to the video module power supply, the video monitoring function on the intelligent lock this moment can be resumeed, carry out video acquisition.

In the third case, the power supply temperature value of the second power supply 5 is greater than or equal to the second threshold value. The second threshold is a preset value, and can be factory-set according to actual product requirements, or can be customized and modified by a user according to requirements. Under the condition that the power supply temperature value of the second power supply 5 is greater than or equal to the second threshold value, it is indicated that the second power supply 5 is in an overheated state, the second power supply 5 is continuously used for supplying power to the camera equipment, and there may be a situation that the power supply is damaged or the camera equipment is damaged, at this time, the security equipment 1 controls the power supply switch 4 to be in a disconnected state, the second power supply 5 does not supply power to the camera equipment 2 any more, and at this time, the camera equipment 2 is turned off. Based on this, under the condition that waiting for the second power supply 5 to cool down and the power supply temperature value is less than the second threshold value, the security protection device 1 can control the power supply switch 4 to be in the connected state, the second power supply path b is in the conducting state, the second power supply 5 can continue to supply power for the camera device 2, and the camera device 2 can continue to carry out multimedia data acquisition under the power supply of the second power supply 5 after the camera device 2 is started.

For example, under the condition that the battery temperature of lithium cell is too high, the switch disconnection on the intelligent lock control follow power supply route on the main power supply route, make the lithium cell on the follow power supply route no longer supply power to the video module, the battery temperature of lithium cell no longer continues to rise, the video monitoring function on the intelligent lock is closed this moment, after the battery temperature of lithium cell is reduced to the safety threshold, the switch connection on the intelligent lock control follow power supply route on the main power supply route, make the lithium cell on the follow power supply route resume and supply power to the video module, the video monitoring function on the intelligent lock can be resumeed this moment, carry out video acquisition.

In a fourth case, the second power source 5 is transformed from the first configuration to the second configuration, the volume of the second power source 5 in the second configuration being larger than the volume of the second power source 5 in the first configuration. The deformation of the second power source 5 from the first configuration to the second configuration may be understood as: the second power supply 5 has a case where there is a component abnormality such as a bulge or the like and the image pickup apparatus 2 cannot be normally supplied with power. Under the condition that the second power supply 5 is deformed, it is indicated that the second power supply 5 is damaged, such as a bulge state caused by overheating, the second power supply 5 is continuously used for supplying power to the image pickup device, and there may be a condition that the power supply is damaged or the image pickup device is damaged, at this time, the security device 1 controls the power supply switch 4 to be in an off state, the second power supply 5 does not supply power to the image pickup device 2 any more, and at this time, the image pickup device 2 is turned off. Based on this, after waiting for the second power supply 5 to be replaced and discharging the security risk that deformation exists, the security device 1 can control the power supply switch 4 to be in the connected state, the second power supply path b is in the conducting state, the second power supply 5 can continue to supply power to the image pickup device 2, and the image pickup device 2 can continue to acquire multimedia data under the power supply of the second power supply 5 after the image pickup device 2 is started.

For example, under the condition that the lithium cell swell warp, the switch disconnection on the intelligent lock control follow power supply route on the main power supply route for lithium cell on the follow power supply route no longer supplies power to the video module, the video monitoring function on the intelligent lock is closed this moment, after changing new lithium cell, the switch connection on the intelligent lock control follow power supply route on the main power supply route, make the lithium cell on the follow power supply route resume and supply power to the video module, the video monitoring function on the intelligent lock can be resumeed this moment, carry out video acquisition.

In a specific implementation, the remaining power of the second power supply 5 can be acquired by a micro control unit mcu (micro Controller unit) in the second power supply 5. The presence or absence of a short in the second supply path b can be obtained by a short detector in the second supply path b. The power supply temperature value of the second power supply 5 can be acquired by the MCU. The form change of the second power supply 5 can be detected by the MCU in the second power supply.

In conjunction with the structure shown in fig. 1, the second power supply 5 may include the following structure, as shown in fig. 3:

the battery cell 501 is configured to receive electric energy provided by the charging device 6, and provide electric energy for the image pickup device 2. The charging equipment can be power supply equipment such as a power bank or commercial power.

The first controller 502 is connected to the second power supply path b where the battery cell 501 is located, and is configured to acquire charge and discharge parameters of the battery cell 501 on the second power supply path b. The first controller 502 may be an MCU, and the collected charging and discharging parameters may include: charging times, charging temperature, voltage, current, percentage of electricity and other parameters.

The electricity meter 503 is connected to the second power supply path b where the battery cell 501 is located, and the electricity meter 503 is connected to the first controller 502, and is configured to update an electricity quantity curve of the battery cell 501 by using the charge and discharge parameters, where the electricity quantity curve represents a corresponding relationship between the voltage of the battery cell 501 and the electricity quantity percentage.

Specifically, the electricity meter 503 may adjust the algorithm parameter of the electricity calculation algorithm of the electric core 501 according to the charge and discharge parameter, so as to calculate the electricity percentage of the remaining electricity corresponding to the discharge voltage of the electric core 501 by using the adjusted electricity calculation algorithm of the algorithm parameter, and further generate the electricity curve of the electric core 501 according to the corresponding relationship between the voltage of the electric core 501 and the electricity percentage, where the electricity curve represents the corresponding relationship between the voltage of the electric core 501 and the electricity percentage. For example, as shown in fig. 4, the horizontal axis in the electric quantity curve represents the discharge time of the lithium battery, the vertical axis represents the discharge voltage of the lithium battery, along with the continuous discharge of the lithium battery, the voltage of the lithium battery continuously decreases from 4300 mv to 3500 mv, in this process, the electric quantity percentage of the lithium battery continuously changes, in this embodiment, after the electricity meter in the lithium battery receives the charge and discharge parameters collected by the MCU in the lithium battery, the electricity meter continuously updates the corresponding relationship between the voltage and the electric quantity percentage in the electric quantity curve, so that the electric quantity curve of the lithium battery is more accurate, thereby showing the discharge voltage of the representative lithium battery that the electric quantity percentage of the user can be more accurate, the user can judge the true remaining electric quantity of the lithium battery according to the electric quantity percentage, so that the user can judge whether to charge the lithium battery according to the electric quantity percentage, avoid the judgment that the electric quantity percentage is inaccurate and leads to make the electric quantity of the lithium battery run out so that the video module is self-error Dynamic shutdown.

In a specific implementation, the second power supply 5 is detachably connected to the image pickup apparatus 2 and the power supply switch 4. In the case where the remaining capacity of the second power supply 5 is low or the second power supply 5 needs to be replaced, etc., the second power supply 5 may be detached from the electronic device for charging or replacement.

Based on this, in conjunction with the structure shown in fig. 3, the following structure may also be included in the second power supply 5, as shown in fig. 5:

the charging interface 504 is capable of connecting the charging device 6, and the charging device 6 forms a charging path c with the battery cell 501 through the charging interface 504, so that the charging device 6 provides electric energy for the battery cell 501. That is to say, the charging device 6, such as a power supply adapter connected to an ac power supply or a charger baby, may provide electric energy to the battery cell 501 through the charging interface 504, and the battery cell 501 is connected to the image capturing apparatus 2 through the power supply interface and provides electric energy to the image capturing apparatus 2. For example, as shown in fig. 6, the lithium battery in the smart lock receives the commercial power converted by the power adapter through the TYPE-C TYPE charging interface or receives the power provided by the power bank through the TYPE-C TYPE charging interface, and provides the power for the video module.

The second controller 505 is connected between the charging interface 505 and the battery cell 501, and is configured to perform charging control on the battery cell 501.

The second controller 505 may be a charging IC (Integrated Circuit Chip, micro electronic device). In a specific implementation, the second controller 505 is specifically configured to: the cell parameters of the cell 501 are collected, and the charging path is disconnected according to the cell parameters of the cell 501. For example, the second controller 505 is connected between the charging interface 504 and the battery cell 501, and the second controller 505 forms a charging path with the charging device 6, the charging interface 504, and the battery cell 501, based on which the second controller 505 disconnects the charging path when the cell parameter of the battery cell 501 meets the power-off condition, so as to avoid the charging device 6 from continuously charging the battery cell 501.

In one implementation, the cell parameter may include a current charge of the cell 501. Based on this, the second controller 505 disconnects the charging path c if the current charge amount of the battery cell 501 is greater than or equal to the third threshold value. The third threshold may be a threshold indicating that the battery cell 501 is fully charged. For example, referring to fig. 6, the charging IC of the lithium battery disconnects the charging path between the TYPE-C interface and the battery cell when the current electric quantity of the battery cell reaches 100%, so as to avoid situations such as overcharge that may be caused by continuing to charge the lithium battery.

In another implementation, the cell parameter may include a cell temperature value of the cell 501. The cell temperature value of the cell 501 may be acquired by a temperature sensor in the second power supply 5. Based on this, the second controller 505 opens the charging path c when the cell temperature value of the battery cell 501 is greater than or equal to the fourth threshold value. The fourth threshold may be a threshold that characterizes the cell as requiring over-temperature protection. For example, the charging IC of the lithium battery disconnects the charging path between the TYPE-C interface and the battery cell when the cell temperature value of the battery cell is higher than a certain threshold, so as to avoid situations such as ignition of the lithium battery, which may be caused by continuous charging of the lithium battery.

In another implementation, the cell parameter may include a current electric quantity of the cell 501 and a cell temperature value of the cell 501. Based on this, the second controller 505 disconnects the charging path c when the current electric quantity of the battery cell 501 is greater than or equal to the third threshold value or when the cell temperature value of the battery cell 501 is greater than or equal to the fourth threshold value. For example, the charging IC of the lithium battery disconnects the charging path between the TYPE-C interface and the battery cell when the battery cell is fully charged or the temperature of the battery cell is too high, thereby avoiding situations such as ignition of the lithium battery, which may be caused by continuous charging of the lithium battery.

It should be noted that the second controller 505 is also connected to the first controller 502, so as to notify the first controller 502 when the second controller 505 disconnects or connects the charging path c, so that the first controller 502 can acquire the charging and discharging parameters of the battery cell 501 on the second power supply path b, such as parameters of obtaining the charging times, the charging temperature, and the charging voltage. For example, a charging IC of the lithium battery is connected to an MCU of the lithium battery, and the MCU records battery cell charging and discharging parameters of the lithium battery.

With continued reference to the structure shown in fig. 3, the second power supply 5 may further include the following structure, as shown in fig. 7:

and a temperature sensor 506 for acquiring a power supply temperature value of the second power supply 5.

Wherein, the electricity meter 503 is connected to the temperature sensor 506, and the electricity meter 503 sends a first message to the first controller 502 when determining that the power supply temperature value of the second power supply 5 is greater than or equal to a second threshold value; the first message contains at least a power supply temperature value for the second power supply 5.

And the first controller 502 sends a second message to the security device 1 when determining that the number of times of over-temperature is greater than or equal to the fifth threshold, so that the security device 1 at least controls the power supply switch 4 to be in the off state. The first controller 502 and the security device 1 may establish a channel capable of message transmission, such as an I2C communication channel, to facilitate transmission of the second message from the first controller 502 to the security device 1.

The number of times of over-temperature is the number of times that the power supply temperature value of the second power supply 5 is greater than or equal to the second threshold, that is, the number of times that the first controller 502 determines that the power supply temperature value in the first message is greater than or equal to the second threshold.

That is to say, the electricity meter 503 updates the electricity quantity curve of the battery cell 501, and also performs the initial determination on the power supply temperature value of the second power supply 5, where the power supply temperature value of the second power supply 5 may also be understood as the battery cell temperature value of the battery cell 501. The first controller 502 is configured to send a first message carrying the power supply temperature value of the second power supply 5 to the first controller 502 when the power supply temperature value of the second power supply 5 exceeds the second threshold value each time the electricity meter 503 determines that the power supply temperature value in the first message exceeds the second threshold value each time the first controller 502 receives the first message of the electricity meter 503 each time, thereby avoiding a situation of erroneous determination of the electricity meter, and send a second message to the security device 1 when the power supply temperature value is continuously determined for multiple times and the security device 1 is triggered to control the power supply switch 4 to be in an off state in time.

The fifth threshold value can be set according to the sensitivity requirement. For example, if a higher sensitivity is required, the fifth threshold may be set to a smaller value, such as 2; if lower sensitivity and higher accuracy are required, the fifth threshold may be set to a higher value, such as 5. For example, as shown in fig. 8, in the case that the temperature sensor detects that the battery temperature of the lithium battery exceeds a certain threshold, the fuel gauge in the lithium battery sends a message to the MCU in the lithium battery, the MCU judges again whether the battery temperature in the message exceeds the certain threshold, and records the judgment result, the number of times that the battery temperature exceeds the certain threshold in the recorded judgment result exceeds 5 times, then the MCU notifies the smart lock, the smart lock disconnects the switch in the slave power supply path, the lithium battery stops continuing to supply power to the video module, and the battery over-temperature protection of the video module is realized.

Based on the above implementation scheme, the first controller 502 may further send a third message to the security device 1 when determining that the number of times of over-temperature is greater than or equal to the fifth threshold, so that the security device 1 sends an alarm message to a terminal, such as a mobile phone, where the alarm message indicates that the second power supply 5 is in a high-temperature state. For example, when the number of times of over-temperature of the lithium battery exceeds 5 times, the MCU in the lithium battery informs the intelligent lock to disconnect the power supply of the lithium battery to the video module, and also informs the intelligent lock to send an alarm short message to a mobile phone of a user, wherein the intelligent lock carries information that the lithium battery is overheated and a fire condition possibly exists, so that the user is informed to check the condition of the intelligent lock and the environment where the intelligent lock is located in time.

In particular, the temperature sensor 506 may include: first temperature detect resistance and second temperature detect resistance, first temperature detect resistance and second temperature detect resistance set up the different positions on second power 5 to more accurate detect the supply temperature value of second power 5.

the electricity meter 503 is connected to the temperature sensor 506, and when determining that the power supply temperature value of the second power supply 5 is greater than or equal to the second threshold, the electricity meter 503 sends a fourth message to the protection circuit 507 to trigger the protection circuit 506 to switch to the off state, so that the second power supply path b between the battery cell 501 and the image pickup apparatus 2 is in the off state.

The protection circuit 507 may be implemented by an over-temperature protection circuit. For example, as shown in fig. 10, an over-temperature protection circuit is disposed in a secondary power supply path formed with the video module in the lithium battery, and when the fuel gauge determines that the battery temperature of the lithium battery collected by the temperature sensor exceeds a certain threshold, a message is sent to the over-temperature protection circuit to trigger the over-temperature protection circuit to switch to a disconnected state, so that the lithium battery does not continue to discharge to the video module, and the lithium battery is prevented from being overheated and causing danger.
