Description

Technical Field

[0001] The present invention relates to the technical field of anti-lost control systems, and in particular to an anti-lost control system for a capacitive pen. Background Art

[0002] With the continuous improvement of people's material life, people's requirements for spiritual life are getting higher and higher. Among them, there are a group of people who are particularly fond of my country's classic quintessence such as Chinese painting and calligraphy. Everyone also knows that creation itself is a gradual error correction process, especially in the early stage of creation, it is a peak period for consuming basic auxiliary materials such as paper and brushes. On the one hand, this not only causes a certain waste of resources, but also causes pollution to the environment. On the other hand, it is also a considerable economic burden for the creators. So is it possible to change this traditional way of creation? If you can create on an electronic device first and then export it, this can not only avoid waste and reduce pollution to the environment, but also reduce the economic cost of the creators.

[0003] The existing positioning technologies on the market generally use LAN or Bluetooth connection technology. Through the Bluetooth connection of the touchpad corresponding to the capacitive pen and the central processor or the same LAN connection, the distance between the capacitive pen and the touchpad signal is roughly judged according to the strength of the signal. When the threshold is exceeded, the wireless communication module will send its own position information in real time accompanied by a warning sound prompt, giving warnings from both visual and auditory aspects, so that users can realize the loss of the capacitive pen in time and quickly find the capacitive pen through the location information in time. However, in actual use, this anti-lost control system not only has great limitations, but also requires multiple electrical components to coordinate the signal processing, which is relatively redundant for smaller capacitive pens. For this reason, we propose a capacitive pen anti-lost control system. Summary of the invention

[0004] In view of the shortcomings of the prior art, the present invention provides a capacitive pen anti-loss control system, which solves the problem that in actual use, the anti-loss control system not only has great limitations, but also requires multiple electrical components to coordinate signal processing, which is relatively redundant for smaller capacitive pens.

[0005] The above technical objectives of the present invention are achieved through the following technical solutions:

[0006] A capacitive pen anti-lost control system comprises a data processing module, the data processing module is located in the middle section of the capacitive pen body, and is used to send operation information to an RFID read-write module to store user information; the RFID read-write module is located in the middle section of the capacitive pen body, and can emit a first radio frequency signal after the operation information is sent to the RFID read-write module; an RFID radio frequency tag is located on a touch panel, and the RFID radio frequency tag emits a second radio frequency signal through a built-in RFID chip; and a central processing unit is capable of receiving the user ID and position ID information contained in the first radio frequency signal and the second radio frequency signal integrated by the data processing module, and issuing a next step instruction.

[0007] Preferably, the data processing module has a wireless transmission module, and the wireless transmission module is used to send the integrated data to the central processing unit.

[0008] Preferably, the data processing module has a data storage module for classifying and storing the received ID numbers to facilitate transmission by the wireless sending module.

[0009] Preferably, the RFID reading and writing module has a receiving antenna for receiving the second radio frequency signal, and the RFID reading and writing module has a transmitting antenna for transmitting the first radio frequency signal.

[0010] Preferably, the capacitive pen anti-lost control system further includes a writing electrode located at the front section of the capacitive pen body and a wiping electrode located at the rear section of the capacitive pen body.

[0011] Preferably, the front section of the capacitive pen body, the middle section of the capacitive pen body and the rear section of the capacitive pen body are detachably snap-connected together.

[0012] Preferably, the writing electrode and the wiping electrode emit signals at different frequencies.

[0013] Preferably, the capacitive pen anti-loss control system further includes a power supply module for providing power to the capacitive pen anti-loss control system, the writing electrode and the wiping electrode.

[0014] Preferably, the capacitive pen anti-loss control system further includes a switch module, and the switch module is used to control the connection relationship between the power module and the capacitive pen system and the capacitive pen anti-loss control system.

[0015] In summary, the present invention mainly has the following beneficial effects:

[0016] 1. The main working principle of the invention is to use the RFID sensing system to realize the alarm and rapid positioning and searching when the capacitive pen is lost. Compared with the traditional WI FI connection or Bluetooth connection positioning method, the RFID positioning method is adopted. Since the RFID reading and writing module and the RFID radio frequency tag have corresponding ID numbers, the detection and positioning are more accurate. At the same time, the anti-lost component starts to work only when the switch module is connected to the main circuit, which increases the endurance of the device and makes the device more durable.

[0017] 2. Through the recognition of radio frequency signals, different frequencies can be adjusted to further increase the correlation between the capacitive pen and the touchpad, making it less susceptible to external influences. The device has higher stability and can still operate normally in an environment that is easily affected. BRIEF DESCRIPTION OF THE DRAWINGS

[0031] refer to Figure 6-Figure 7 , the power module 4 and the switch module 5 are electrically connected together, the writing electrode 8 and the wiping electrode 9 constitute a capacitive pen system, the RFID radio frequency tag 10, the RFID reading and writing module 3, the data processing module 2 and the central processor 11 constitute a capacitive pen anti-lost system, and the switch module 5 is electrically connected to the capacitive pen system and the capacitive pen anti-lost system respectively, so that the capacitive pen anti-lost system can control the connection status of the two at the same time, ensuring that the device can operate normally under the premise of normal operation of each module, and there will be no problem that a certain module is always in a connected state and wastes extra energy;

[0032] refer to Figure 8 The data processing module 2 has a wireless transmission module, which is used to send the integrated data to the central processing unit. The data processing module 2 has a data storage module, which is used to classify and store the received number ID to facilitate the transmission of the wireless transmission module.

When the capacitive pen is separated from the touch panel and is ready to be used, the switch module 5 is turned on to connect the power module 4 and the main circuit composed of the capacitive pen anti-lost control system, the writing electrode 8 and the wiping electrode 9. After the main circuit issues an operation instruction, the data processing module controls the RFID reader-writer module to transmit the first radio frequency signal through the transmitting antenna to match the RFID radio frequency tag 10 with the corresponding number, and enables the RFID radio frequency tag 10 to send back the second radio frequency signal containing the position number to the RFID reader-writer module. signal, and at the same time, the second radio frequency signal received by the receiving antenna is integrated by the data storage module and sent to the wireless receiving module in the central processor, so as to ensure that the central processor can receive the user and location IDs contained in the first radio frequency signal and the second radio frequency signal, and obtain the state and location of the capacitive pen by comparing the ID number with the cloud database of the central processor.
