[0052] The preferred embodiments of the present invention are described below in conjunction with the accompanying drawings. It should be understood that the preferred embodiments described herein are only used to illustrate and explain the present invention, and are not used to limit the present invention.

[0053] like Figure 1 As shown, the embodiment of the present invention provides a rugged tablet computer with a hot-swap battery, comprising:

[0054] A first detection module, used to detect first power information of the main battery, and determine whether it is less than a first preset power threshold;

[0056] The starting module is used to start the backup battery to supply power to the rugged tablet computer body when the first detection module determines that the first power information is less than a first preset power threshold.

[0057] The working principle of the above technical solution is as follows: the first detection module is used to detect the first power information of the main battery and determine whether it is less than the first preset power threshold; the sending module is used to send a replacement request to the user terminal when the first detection module determines that the first power information is less than the first preset power threshold, so that the user can replace the main battery in time. The starting module is used to start the backup battery to power the three-proof tablet computer body when the first detection module determines that the first power information is less than the first preset power threshold. The first preset power threshold is 3%. Both the main battery and the backup battery are hot-swappable batteries.

[0058] The beneficial effects of the above technical solution are as follows: a main battery and a backup battery are set. When the three-proof tablet computer is working normally, the main battery is used to supply power, and the backup battery is not used. The backup battery only supplies power to the system when the main battery is replaced online, which effectively ensures worry-free replacement of the main battery, avoids interruption of ongoing business, and causes incomplete data records. At the same time, it avoids confusion when replacing batteries, and avoids affecting the service life of another battery when one battery fails, thereby reducing costs.

[0062] The charging module is used to control the new main battery to charge the backup battery when the third detection module determines that the third power information is greater than a third preset power threshold.

[0063] The working principle and beneficial effects of the above technical solution: The second preset power threshold is 50%. The second detection module is used to detect the second power information of the backup battery after replacing the new main battery, and determine whether it is less than the second preset power threshold; when it is determined that the second power information is less than the second preset power threshold, a charging demand is generated; the third detection module is used to detect the third power information of the new main battery according to the charging demand, and determine whether it is greater than the third preset power threshold; the third preset power threshold is 80%. The charging module is used to control the new main battery to charge the backup battery when the third detection module determines that the third power information is greater than the third preset power threshold. The main battery can charge the backup battery to ensure the availability of the backup battery, avoid frequent replacement of the backup battery, and use it more conveniently.

[0064] like Figure 3 As shown, according to some embodiments of the present invention, the charging module includes:

[0065] An establishment module is used to establish a new connection relationship between the main battery and the backup battery;

[0066] The first setting module is used to set the charging delay time;

[0067] The judgment module is used to obtain the actual voltage value of the backup battery and judge whether the actual voltage value is between the minimum output voltage and the maximum output voltage of the new main battery; when it is determined that the actual voltage value is between the minimum output voltage and the maximum output voltage of the new main battery, after waiting for the charging delay time, the new main battery is controlled to charge the backup battery.

[0068] The working principle and beneficial effects of the above technical solution: an establishment module is used to establish a connection relationship between a new main battery and a backup battery; a first setting module is used to set the charging delay time; a judgment module is used to obtain the actual voltage value of the backup battery and judge whether the actual voltage value is between the minimum output voltage and the maximum output voltage of the new main battery; when it is determined that the actual voltage value is between the minimum output voltage and the maximum output voltage of the new main battery, after waiting for the charging delay time, the new main battery is controlled to charge the backup battery. Avoid charging failure prompts caused by signal delays when the new main battery charges the backup battery, so as to facilitate stable and safe charging of the backup battery by the new main battery. Set the charging delay time to 2-5s.

[0069] According to some embodiments of the present invention, the charging module includes:

[0071] A second control module, used for controlling the new main battery to charge the backup battery at a second charging voltage in a second charging stage;

[0072] A third control module, used for controlling the new main battery to charge the backup battery at a third charging voltage in a third charging stage;

[0073] Among them, the second charging voltage, the third charging voltage and the first charging voltage decrease in sequence.

[0074] The working principle of the above technical solution: The first charging stage is the recovery stage, which is used to restore the voltage and temperature of the backup battery to a normal state to avoid damage to the backup battery. The first charging voltage is: U1+K1*(U2-U1), where U1 is the minimum output voltage of the new main battery; U2 is the maximum output voltage of the new main battery; K1 has a value range of (0.1, 0.3), which is related to the required time for recovery. The smaller the required time for recovery, the larger the value of K1. The first charging stage is a high-speed charging stage, which is used to quickly charge the backup battery after it returns to a normal state, so as to increase the charging rate. The second charging voltage is: U1+K2*(U2-U1), and K2 has a value range of (0.7, 1), which is related to the required time for charging. The smaller the required time for charging, the larger the value of K2. The third charging stage is a buffer stage, which is used to steadily charge the backup battery after the high-speed charging is completed, reduce the charging speed, and avoid the backup battery from being damaged by virtual electricity due to continuous high-speed charging. The third charging voltage is: U1+K3*(U2-U1), the value range of K3 is (0.4, 0.6), which is related to the stable demand time. The shorter the stable demand time, the larger the value of K3.

[0075] The beneficial effects of the above technical solution are: based on the charging module, the new main battery is controlled to charge the backup battery, and different control strategies are adopted in different charging stages to ensure the charging rate, while maintaining the backup battery, avoiding damage to the backup battery, and extending the service life of the backup battery.

[0081] The determination module is used to determine the charging evaluation parameter value according to the first consumption parameter, the second consumption parameter and the third consumption parameter; determine the charging effect level of the new main battery on the backup battery according to the charging evaluation parameter value and display it.

[0082] Working principle of the above technical solution: In this embodiment, calculating the first consumption parameter in the first charging stage includes:

[0083]

[0084] Among them, S is the first consumption parameter; U zb is the initial voltage of the backup battery before the first charging stage begins; U za I is the termination voltage of the backup battery after the first charging stage; h is the charging current in the first charging stage; T h is the duration of the first charging stage; U xa The initial voltage of the new main battery before the first charging stage begins; U xb I is the new main battery termination voltage after the first charging stage ends; m is the current consumption in the first charging stage; T m For power consumption time.

[0085] The principle of calculating the second consumption parameter in the second charging stage is consistent with that of calculating the third consumption parameter in the third charging stage, and both are calculated based on the previous charging stage, which will not be repeated here.

The closer the charging evaluation parameter value is to 0, the better the charging effect is. Different weight coefficients are set for each charging stage, and weighted calculations are performed based on the first absolute value, the second absolute value and the third absolute value and the corresponding weight parameter, so as to accurately obtain the charging evaluation parameter value, and then accurately determine the new charging effect level of the main battery to the backup battery.

[0102] When it is determined that the size parameter is greater than the preset size parameter, it indicates that an abnormality occurs in the backup battery, and a replacement demand for the backup battery is generated and sent to the user terminal.

When it is determined that the backup battery is abnormal, it is repaired or replaced in time to ensure the reliability of the backup battery, and then when the main battery is replaced, the backup battery powers the system to avoid data loss.

[0104] According to some embodiments of the present invention, it also includes: a first alarm module, which is used to detect the real-time current of the backup battery and calculate the difference between the real-time current and the preset reference current when the startup module starts the backup battery to power the three-proof tablet computer body; when it is determined that the difference is not within the preset difference range, send an automatic backup request to the three-proof tablet computer body and issue an alarm prompt.
