Description

Technical Field

[0001] The utility model relates to the field of teaching auxiliary equipment, in particular to a wirelessly upgradeable Bluetooth electronic dictionary. Background Art

[0002] Currently, some electronic dictionaries purchased and used in closed-door primary and secondary schools typically lack internet connectivity to prevent students from using the devices for purposes other than learning. Consequently, these electronic dictionaries often require data cables to update their vocabulary databases or lack an update function. However, due to the large number of students in school environments, each update requires a significant workload. Therefore, a wirelessly updateable Bluetooth electronic dictionary has been proposed to address this issue. Utility Model Content

[0003] The technical problem to be solved by the present invention is to overcome the existing electronic dictionary, which has a large number of users and a huge workload for each upgrade. The present invention proposes a wireless upgrade Bluetooth electronic dictionary to improve the user experience and meet the user's needs for vocabulary updates and function upgrades.

[0004] The technical solution adopted by the present invention to solve the technical problem is as follows: the present invention is a wirelessly upgradeable Bluetooth electronic dictionary, comprising: an electronic dictionary, characterized in that a keyboard, a display, and a battery compartment are provided on the surface of the housing of the electronic dictionary, and a circuit board of the electronic dictionary is connected to a main control chip, a memory chip, a Bluetooth module, and a battery module;

[0005] The main control chip is an NRF51802 chip or an RJM32W206 chip, and the main control chip is connected to the storage chip, keyboard, display, and battery module respectively;

[0006] The memory chip is a GD25Q16 chip, and the memory chip is connected to the main control chip;

[0007] The Bluetooth module is a Bluetooth adapter, which is connected to the main control chip and the Bluetooth antenna;

[0008] The power module is a power management and battery module, which is connected to the main control chip. The battery is a CR2032 lithium manganese battery.

[0009] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0010] 1. Upgrading is convenient and fast through devices such as Bluetooth signal terminal transceivers or smartphones, without the need for complicated connection cables, which simplifies the upgrade process and improves the user experience. Users select the content to be upgraded through a dedicated application or software platform, and the update data is transmitted to the electronic dictionary, enabling rapid updates of the vocabulary and software.

[0011] 2. The utility model directly finds words suitable for this grade by initially selecting different dictionaries, avoiding recommending English words that are not involved in this grade or age group, which is more conducive to students' English learning. BRIEF DESCRIPTION OF THE DRAWINGS

[0016] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0017] A wirelessly upgradeable Bluetooth electronic dictionary comprises: an electronic dictionary, wherein a keyboard, a display, and a battery compartment are provided on a housing surface of the electronic dictionary, and a circuit board of the electronic dictionary is connected to a main control chip, a memory chip, a Bluetooth module, and a battery module;

[0018] The main control chip is NRF51802 chip or RJM32W206 chip, and the main control chip is connected to the storage chip, keyboard, display and battery module respectively;

[0019] The memory chip is a GD25Q16 chip, which is connected to the main control chip;

[0020] The Bluetooth module is a Bluetooth adapter, which is connected to the main control chip and the Bluetooth antenna;

[0021] The power module is for power management and battery. The power module is connected to the main control chip, and the battery is a CR2032 lithium manganese battery.

[0022] Dictionary data upgrade:

[0023] Prepare a main device with Bluetooth signal interaction function (such as a background system + signal relay device or a mobile phone, etc.) and an electronic dictionary; turn on the Bluetooth communication function of both parties (the electronic dictionary determines the options displayed on the screen by pressing buttons), and the two parties establish a communication connection; the main device sends a "dictionary upgrade data packet" to the electronic dictionary, and the electronic dictionary can be operated to select or automatically controlled by the main control chip to upgrade. The electronic dictionary receives the data through the Bluetooth antenna, and the Bluetooth signal is processed by the Bluetooth module and controlled by the built-in program of the main control chip. The content of the "dictionary upgrade data packet" is saved to the storage chip, replacing and overwriting the original data.

[0024] Dictionary usage:

[0025] Use the keyboard to select the dictionary options for different publishers and different grades that appear on the display, and enter the corresponding dictionary after confirming. Enter text information through the keyboard. For example, if you enter the letter "a" on the keyboard, the main control chip will call the dictionary data in the storage chip, and the display will show the search results, and the words containing the letter "a" will be displayed on the display. For example, if you enter the letters "ab" on the keyboard, the words containing the letters "ab" will be displayed on the display, and so on. Select the corresponding word, and the corresponding phonetic symbols, meanings, etc. will be displayed. Or by entering Chinese words, the main control chip will directly call the corresponding phonetic symbols, meanings, etc. in the current Chinese dictionary in the storage chip.

[0026] By initially selecting different dictionaries, you can directly find words that are suitable for this grade and avoid recommending English words that are not covered in this grade or age group.

[0027] Although the embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and variations may be made to these embodiments without departing from the principles and spirit of the present invention, and the scope of the present invention is defined by the appended claims and their equivalents.
