Description

Technical Field

[0001] The present invention relates to the field of fire protection technology, and in particular to a charging fire safety monitoring method and monitoring device. Background Art

[0002] The charging plug can provide energy replenishment for the device to be charged, making it convenient for the device to be charged to replenish energy.

[0003] Lithium-ion batteries are the most commonly used type of battery for devices to be charged. During the charging process, lithium ions move from the negative electrode to the positive electrode of the battery. When the battery is close to full charge, the concentration difference of lithium ions decreases, resulting in a decrease in the driving force for lithium ions to move to the positive electrode, so the charging speed will slow down.

[0004] At the same time, in order to protect the battery and extend its service life, the device to be charged and the charging plug usually adopt a strategy called "constant voltage charging". Under this strategy, when the battery is close to full charge, the charging current will gradually decrease to avoid overcharging and overheating of the battery. However, if the device is aging, the charging plug will overheat and it will be easy to cause a fire.

[0005] Therefore, at present, it is easy for many charging devices to be concentrated in charging stations waiting for charging. This situation is not only not conducive to the efficient operation of the charging station, but also prone to overheating due to centralized charging, which poses a fire safety hazard and may cause great risks to surrounding users.

[0035] An embodiment of the present invention provides a fire safety monitoring method for charging, which is applied to a charging station, wherein at least one camera device is arranged in the charging station, and the charging station includes a plurality of charging plugs, such as Figure 1 As shown, the above-mentioned charging fire safety monitoring method mainly includes:

[0036] Step S101, obtaining operation information sent by each charging plug; judging whether there is an idle charging plug based on the operation information; if not, obtaining a real-time image of the charging station captured by a camera device.

[0037] Specifically, the main control box communicates with each charging plug; the operating information sent by the charging plug usually includes whether it is in working state, charging power, charging power (or charging percentage), internal temperature and other data. The main control box determines whether there is an idle charging plug based on the operating information of each charging plug. When there is no idle charging plug, in order to reduce the slow charging stage of the charging plug in the charging state and other waiting devices to be charged waiting for too long, the power station application platform obtains the real-time image of the charging station captured by the camera device at this time. The camera device can be one or more.

[0038] Step S102, based on the real-time image of the charging station, determine whether there is a device to be charged waiting for charging, if so, obtain the number of devices to be charged in the waiting state, recorded as the number n.

[0039] Specifically, it is determined whether there is a device to be charged waiting for charging by using image recognition technology, and the number of devices to be charged in the waiting state is obtained.

[0040] Step S103, based on the operation information, obtaining the number a of charging plugs that have completed charging and the number b of charging plugs whose charging percentage is greater than a preset percentage; and recording the charging plugs whose charging percentage is greater than the preset percentage as stoppable charging plugs.

[0041] Specifically, deep discharge (charge close to 0%) and deep charge (full charge to 100%) will have a negative impact on the health of the battery. The life of a battery is related to the number of charge and discharge cycles it has. Deep discharge and deep charge will increase the number of cycles, thereby accelerating battery aging. It is generally recommended to charge within the range of 80% to 90%. This can reduce the number of charging cycles while ensuring that the battery has enough power for daily use. Therefore, the preset percentage is usually set to 80%, and the charging plug with a charging percentage greater than the preset percentage charges more power to the device to be charged. When the device to be charged stops charging at 80% to 90% of power, it is also beneficial to improve the battery life of the device to be charged.

[0042] Step S104, based on the quantitative relationship between a, b and n, when the stoppable charging plug is needed to charge some of the devices to be charged, a first request message is pushed to users connected to the charging plugs corresponding to the number of devices to be charged; the first request is used to prompt the user of the current charging percentage and request the user to stop charging; after receiving a response instruction in response to the first request, the corresponding charging plug is controlled to stop charging and the indicator light is displayed as a display state corresponding to the completion of charging.

[0043] Specifically, based on the quantitative relationship between a, b and n, when the stoppable charging plug is needed to charge some of the devices to be charged, a first request message is pushed to users connected to the charging plugs of the corresponding number of devices to be charged; the first request is used to prompt the user of the current charging percentage and request the user to stop charging; the user can click on the first request in the smart terminal to respond, and after receiving the response instruction to the first request, the corresponding charging plug is controlled to stop charging and the indicator light is displayed as the corresponding display state of charging completion, after which the user can unplug the charging plug and drive out the device to be charged, thereby facilitating the charging of other devices to be charged in the waiting state.

[0044] Specifically, by acquiring the operation information of each charging plug, the working status of the charging plug can be monitored in real time; by collecting the real-time image of the charging station through the camera device, it is determined which charging plugs can stop charging, so as to provide services for other devices to be charged. At the same time, according to the quantity relationship, the first request information can be pushed to the corresponding number of devices to be charged, prompting the user of the current charging percentage and requesting the user to stop charging. After the user confirms, the charging plug is controlled to stop charging. After the user leaves the position corresponding to the charging plug, other waiting devices can be charged, thereby improving the charging efficiency.

[0045] In some embodiments, based on the quantitative relationship among a, b and n, determining that the stoppable charging plug is required to charge some of the devices to be charged includes:

[0046] Determine whether a is greater than or equal to n; if so, determine that it is not necessary to stop the charging plug from charging some of the devices to be charged;

[0047] If not, determine whether a+b is greater than n; if so, determine that na stoppable charging plugs are needed for charging; if not, determine that b stoppable charging plugs are needed for charging.

[0048] Specifically, if a is greater than or equal to n, it means that the number of charging plugs that have been charged is sufficient to meet the needs of all devices to be charged. If a is less than n, it means that other charging plugs need to be added to meet the demand.

[0049] In some embodiments, after determining that na stoppable charging plug is needed for charging, the method includes:

[0050] Determine whether na charging plugs receive a response instruction after a preset time; if not, resend the first request information to some or all of the a+bn charging plugs based on the relationship between the number c of charging plugs that have not received the response instruction and a+bn.

[0051] In some embodiments, based on the quantitative relationship among a, b and n, determining that the stoppable charging plug is required to charge some of the devices to be charged includes:

[0052] Determine whether a is greater than or equal to n; if so, determine that it is not necessary to stop the charging plug from charging some of the devices to be charged;

[0053] If not, it is determined that b stoppable charging plugs are needed for charging.

[0054] In some of the embodiments, the method further includes: sending reward points to the user account that sends the response instruction.

[0055] In some of the embodiments, a first time duration from the time when the charging plug, which has completed charging and is still connected to the device to be charged, stops charging is obtained; it is determined whether the first time duration is greater than a preset time duration; if so, a first prompt message is pushed to the corresponding user; the first prompt message is used to remind the user.

[0056] In some of the embodiments, the method further includes: monitoring temperature data of each charging plug; sending an alarm message when the temperature of at least one of the charging plugs is greater than a first preset value; and disconnecting power supply to the corresponding plug when the temperature of at least one of the charging plugs is greater than a second preset value.

[0057] Specifically, the above scheme can issue a warning when the temperature of the charging plug is greater than the first preset value (and the temperature is overheated); the second preset value is greater than the first preset value; and the power is cut off when the temperature is greater than the second preset value to avoid the possibility of fire.

[0061] The third processing module 203 is used to: obtain the number a of charging plugs that have completed charging and the number b of charging plugs whose charging percentage is greater than a preset percentage based on the operation information; and record the charging plugs whose charging percentage is greater than the preset percentage as charging plugs that can be stopped;

[0062] The fourth processing module 204 is used to: based on the quantitative relationship between a, b and n, when the stoppable charging plug is needed to charge some of the devices to be charged, push a first request message to users connected to the charging plugs corresponding to the number of devices to be charged; the first request is used to prompt the user of the current charging percentage and request the user to stop charging; after receiving a response instruction in response to the first request, control the corresponding charging plug to stop charging and display the indicator light as a display state corresponding to the completion of charging.
