1. Field of the Invention
The invention is related to a wireless transmission data access device with integrated charging function. It especially utilizes a method of board-to-board or all-in-one to integrate the charging function into the wireless transmission data access device and give users charging function in the mobile wireless network device.
2. Description of the Prior Art
As the gradual spread of wide band network, in an environment with VoIP (Voice over IP) function, wireless network telephones and wireless transmission data access devices are both necessary fundamental requirements.
The wireless network device (such as: Wi-Fi VoIP Phone{grave over ()}Wi-Fi with GPRS combo VoIP Phone{grave over ()}Wi-Fi with GSM combo VoIP Phone{grave over ()}Wi-Fi with PHS combo VoIP Phone, Wi-Fi with WCDMA combo VoIP Phone{grave over ()}PDA Software IP Phone, etc.) provides the convenience of bringing. It comprises cells which can be charged over and over again as voltage/current sources and must match a charge set to ensure sufficient electric power for use. The wireless transmission data access device (Wireless Wi-Fi AP Device) comprises a wireless access point, a wireless AP router, and a wireless AP gateway to integrate wireless network transmission data access function and the wireless network device as one unit. The application of Wi-Fi transmission techniques comprises IEEE802.11b, IEEE802.11g, IEEE802.11a wireless transfer protocols.
Wireless network devices must transfer voice and data to remote destination through a wireless access point, a wireless AP router or a wireless AP gateway that have been already mounted in an environment and are authenticated by wireless system registration, and must use charger set to ensure the sufficient electric power. In an environment without any wireless network, wireless network device will be useless. However, the voltage/current source supplied to mobile wireless network device and wireless transmission data access device are independent and irrelevant. As for users, when the power of the mobile wireless network device isn't enough, users must charge it with an additional charger set. It will increase the waste of power, make it inconvenient to use, increase the space for mounting, and need to find an outlet. All of these increase the inconvenience and trouble in use.
The main purpose of the invention is to provide a wireless transmission data access device with integrated charging function, which is a charger set integrated from the wireless transmission device with network wireless device function such as a wireless access point, a wireless AP router or a wireless AP gateway, and is used to charge the mobile wireless network device and transfer voice and data.
The other purpose of the invention is that the charger set and the wireless transmission data access device are integrated in a housing by board-to-board or all-in-one method. No matter where the wireless transmission data access device is mounted, it has the function of charging the wireless network circuit at any time and can prolong the time of use of wireless network telephones.
The charger set 50 comprises a microprocessor 52, a charging indication panel 53, an error check circuit 54, a protecting circuit 55, a charging voltage check 56, and a charging current check 57. The charging techniques which we use comprise but are not restricted in large current quick charging method, voltage comparison method, and single-chip microcomputer voltage difference controlling method, etc. The embodiment example of the invention uses single-chip microcomputer voltage difference controlling method. All the components are controlled by the microprocessor 52. The voltage/current come from the voltage/current source input circuit 51 into the charger set 50. The charging current check 57 and the charging voltage check 56 controlled by the microprocessor 52 produce a suitable stable charging voltage to charge the charging cells inside the wireless network device and prevent the suddenly increasing voltage/current by the protecting circuit 55. The error check circuit 54 checks the charging status, send signals to the microprocessor 52, and drive the charging indication panel 53 to show the charging status.
As shown in
Thus, the wireless transmission data access device with integrated charging function which is provided by the invention not only increases the charging function besides the data and voice transmission function of the wireless transmission data access device but also promotes the convenience of use of the wireless network device. The invention never appeared before, and has the value of industry. It fits all the requirement of invention. We apply for a patent according to the law and hope it to be approved as soon as possible. Thank you very much.
We have provided a detailed description of the invention. What we have described is only one of the better embodiment examples. It can't restrict the embodiment scope of the invention. All the variation and modification according to this invention should still belong to the patent scope of the invention.
