Description

Technical Field

[0001] The present invention relates to the technical field of intelligent information display of batteries for civil or commercial unmanned aerial vehicles, and in particular to a battery information viewing device. Background Art

[0002] At present, the application of drone smart batteries is becoming more and more common, and smart batteries using CAN interface communication are also gradually being widely used. Smart batteries using CAN interface communication can not only improve the reliability of data transmission between the battery and the drone, but also upload the drone battery data to the host computer through the CAN interface to view detailed information inside the drone battery.

[0003] However, uploading drone battery data to the host computer through the CAN interface and viewing detailed information inside the battery has the following disadvantages.

[0004] First of all, the communication protocol of the CAN interface is relatively complex, and it is necessary to use a CAN box to parse the data and cooperate with the corresponding host computer software to view the internal data of the drone battery. Therefore, if you need to view the drone battery information in real time when using the drone outdoors, it is very inconvenient.

[0005] Secondly, when judging the real-time information of the drone battery, it is necessary to collect and analyze multiple sets of data in the battery. Therefore, when using the drone outdoors, it is necessary to use a computer with host computer software installed to analyze the collected multiple sets of battery data, judge and view the drone battery information. This makes it very inconvenient to view the drone battery information outdoors, which directly affects the efficiency of testing the drone outdoors.

[0006] Based on the above reasons, in order to better improve the efficiency of outdoor drone testing and realize more convenient real-time viewing of drone battery information, it is urgent to provide a portable drone battery information viewing device. This information viewing device can not only realize the real-time analysis and display of drone battery CAD data, multiple sets of battery information can be switched and displayed, but also is compatible with the isolated CAN communication interface, small in size, easy to carry, and can be directly plugged and adapted with the smart battery CAN interface, without being restricted by the outdoor environment. Summary of the invention

[0007] In view of the shortcomings of the prior art, the purpose of the present invention is to propose a battery information viewing device. The drone battery information viewing device provided by the present invention can not only realize the real-time analysis and display of drone battery CAN data, but also is compatible with the isolated CAN communication interface, has a small size, is easy to carry, can be directly plugged and adapted with the smart battery CAN interface, and is not restricted by the outdoor environment.

[0008] In order to achieve the above object, the present invention adopts the following technical solutions:

[0009] A battery information viewing device, comprising a CAN communication unit, a control unit, a display unit and a power supply unit;

[0010] The CAN communication unit is used to connect to a first CAN communication interface of the battery to obtain first battery information;

[0021] Further, according to any of the above-mentioned devices, the device further comprises a button, the button is connected to the controller, and the button comprises:

[0022] A startup module, used for starting the battery information viewing device;

[0023] and\or

[0025] Further, according to any of the above-mentioned devices, the device also includes a charging and debugging port, and the charging and debugging port is connected to the power supply device through the battery charging management unit.

[0026] Furthermore, the charging debugging port is a USB debugging port.

[0028] Furthermore, the display unit is an LED or LCD display screen.

[0029] The beneficial effects of the present invention are:

[0030] 1. The battery information viewing device of the present invention adopts a CAN communication unit, a control unit, a display unit and a power supply unit, wherein the CAN communication unit is used to connect to the first CAN communication interface of the battery to obtain the first battery information; the control unit is used to parse the first battery information and generate the second battery information; the display unit is used to display the second battery information; and the power supply unit is used to supply power to the battery information viewing device of the present invention. The battery information viewing device of the present invention can not only be directly plugged and adapted with the first CAN communication interface of the drone intelligent battery, without being restricted by the outdoor environment, but also can realize the real-time parsing and display of the drone battery information.

[0031] 2.

[0036] 5. The battery information viewing device of the present invention is equipped with a built-in charging debugging port, which can be connected to a built-in rechargeable battery through a battery charging management unit to charge the built-in battery. At the same time, the charging debugging port can also be used as a debugging port for external communication.

[0040] The present application will be further described in detail below in conjunction with the accompanying drawings and embodiments. It is to be understood that the specific embodiments described herein are only used to explain the relevant invention, rather than to limit the invention. It should also be noted that, for ease of description, only the parts related to the invention are shown in the accompanying drawings.

[0041] Embodiment 1:

[0042] It should be noted that, in the absence of conflict, the embodiments and features in the embodiments of the present application can be combined with each other. Figure 1 The present application is described in detail with reference to embodiments.

[0043] like Figure 1 As shown, in order to solve the deficiencies in the prior art, the technical solution of the present invention is:

[0044] A battery information viewing device, comprising a CAN communication unit, a control unit, a display unit and a power supply unit; the CAN communication unit is used to connect to the first CAN communication interface of the battery to obtain first battery information; the control unit is used to parse the first battery information and generate second battery information; the display unit is used to display the second battery information; and the power supply unit is used to power the device.

[0045] In this embodiment, the CAN communication unit is a controller area network (CAN) communication unit.

[0046] The CAN communication unit includes: a second CAN communication interface, used to connect to the first CAN communication interface of the battery; and a CAN transceiver chip, used to obtain the first battery information.

[0047] In this embodiment, the second CAN communication interface is a plug-in connector.

[0048] In this embodiment, the first CAN communication interface is an isolated CAN communication interface; the power supply unit is also used to supply power to the isolated CAN communication interface through the CAN communication unit.

[0049] In this embodiment, the power supply unit is used to power the battery information viewing device on the one hand, and on the other hand, it is used to power the isolated CAN communication interface used by the drone intelligent battery. Since the bus of the isolated CAN communication interface is physically isolated, it requires external power supply to work. The power supply unit of the battery information viewing device illustrated in this embodiment can power the isolated CAN communication interface.

[0050] The device in this embodiment also includes a button, which is connected to the controller. The button includes: a power-on module for starting the battery information viewing device; and a page turning module for turning the information on the display unit to switch and display multiple groups of battery information.

[0051] The display unit in this embodiment is a relatively small LED display screen, which displays the voltage, current, capacity, temperature, life and other information inside the battery. Due to the small size of the display screen, the information of the drone smart battery cannot be displayed on the screen at once. Therefore, it is necessary to press a button to turn the information on the display screen, switch to display multiple groups of battery information, and thus display the acquired information of all drone smart batteries.

[0052] The device in this embodiment also includes a charging and debugging port, which is connected to the power supply device through the battery charging management unit.

[0053] In this embodiment, the charging debugging port is a USB debugging port, which can be used not only to connect a power supply device but also to be used as an external communication debugging port.

[0054] In this embodiment, the power supply device is a built-in rechargeable battery, and the built-in rechargeable battery is a lithium battery.

[0055] To facilitate understanding of the present invention, the battery information viewing device provided by the present invention is further described below based on the device structure of the present invention and the application process in the embodiment:

[0056] When the information of the drone smart battery is viewed in real time, the battery information viewing device of this embodiment is first connected to the first CAN communication interface (isolated CAN communication interface) of the drone smart battery through the plug-in second CAN communication interface. The start module of the button is pressed to start the battery information viewing device of this embodiment.

[0057] After starting the device, the power supply unit in the device supplies power to the isolated CAN communication interface in the drone. At the same time, the CAN transceiver chip obtains the first battery information of the drone's intelligent battery through the isolated CAN communication interface and sends the information to the control unit. The control unit parses the first battery information and generates second battery information. The display unit displays the parsed second battery information through the LED screen, thereby obtaining the information of the drone's intelligent battery and displaying it on the display screen synchronously. By pressing a button, the information on the display screen can be turned, and multiple groups of battery information can be switched to display, thereby realizing the real-time viewing function of the drone's intelligent battery information.

[0058] Embodiment 2

[0059] The features of this embodiment that are the same as those of the first embodiment are not described in detail. The features of this embodiment that are different from those of the first embodiment are as follows:

[0060] like Figure 2 As shown, the first CAN communication interface used by the drone intelligent battery in this embodiment is a direct CAN communication interface. Since the bus of the direct CAN communication interface is physically connected to the internal circuit of the drone, it can work without external power supply. Therefore, the power supply unit of the battery information viewing device in this embodiment only needs to power the battery information viewing device and synchronously display the acquired drone intelligent battery information on the display screen.

[0061] In addition to the display unit described in Embodiment 1 and Embodiment 2 being an LED display screen, the display unit can also be set to other forms of display screens as long as it can display the information of the drone smart battery in real time, for example, it can be set to an LCD display screen. The display unit can be an LED or LCD display screen to display the information of the drone smart battery in real time.

[0062] The drone battery information viewing device exemplified in Example 1 and Example 2 can not only realize the real-time analysis and display of drone battery CAD data, multiple sets of battery information can be switched and displayed, but also is compatible with the isolated CAN communication interface, has a small size, is easy to carry, can be directly plugged and adapted with the smart battery CAN interface, and is not restricted by the outdoor environment.

[0063] The above description is only a preferred embodiment of the present application and an explanation of the technical principles used. Those skilled in the art should understand that the scope of the invention involved in the present application is not limited to the technical solution formed by a specific combination of the above technical features, but should also cover other technical solutions formed by any combination of the above technical features or their equivalent features without departing from the inventive concept. For example, the above features are replaced with the technical features with similar functions disclosed in this application (but not limited to) by each other.
