Abstract
The invention discloses an auxiliary call help-seeking device, comprising Bluetooth module, CODEC, microphone, telephone receiver and antenna, where the antenna is connected with radio frequency interface of the Bluetooth module via radio frequency line, the Bluetooth module is connected with the CODEC, the microphone and the telephone receiver are connected with the CODEC via analog audio interface to input or output the analog signals converted by the CODEC, and help key and distress key are connected with signal input end of the Bluetooth module. And the invention is used to automatically dial prestored help seeking number and 110. And the invention transmits help seeking signal by Bluetooth radio communication technique, needing no complex drive mechanism and having advantages of small volume, portable and convenient to use.
Description
Technical field
The present invention relates to short-distance wireless communication technology, be specifically related to a kind of auxiliary telephone recourse device.
Technical background
Bluetooth (Bluetooth) technology is the short distance radio communication standards of being joined together to develop by mobile operator and mobile computing company, is used for designing setting up a kind of small-sized, economic, short-range Radio Link between portable computer, mobile phone and other mobile device.The frequency range of regulation and stipulation work is public ISM band, and peak data rate can reach 1Mbps.At present the extensive fields of bluetooth applications is exactly a mobile phone, can use the Bluetooth wireless technology transporting speech when making a phone call, and realizes the wireless connections of other equipment and mobile phone.Being extensive use of of mobile phone brought many convenience to people, but can not conveniently have been used in some specific occasion.For example when people alone a people run into various dangerously when needing to report to the police, use the phone may be dangerous more; When disadvantaged group such as the old,weak,sick and disabled face a danger when being difficult to move, call that seek help can be very difficult ... in these cases, obviously there is deficiency in mobile phone.And do not have specialized apparatus to solve required problem at present yet.
Summary of the invention
The purpose of this invention is to provide the above-mentioned specific occasion of a kind of convenience and use, realize not having the obviously device of seeking help automatically of performance.
The object of the present invention is achieved like this: auxiliary telephone recourse device is characterized in that being made up of bluetooth module, coding decoder CODEC, microphone, receiver, help key, key in danger and antenna.Antenna links to each other with the radio frequency interface of bluetooth module by radio frequency line, is used for and the communicating by letter of mobile phone; Bluetooth module integrated coding decoder CODEC; Microphone links to each other with coding decoder CODEC by analog audio interface with receiver, and the analog signal that coding decoder CODEC converts to is carried out input and output; Help key links to each other with the signal input part of bluetooth module with key in danger, is used for seek help number and alarm call that automatic dial-out is stored in bluetooth module in advance.Described coding decoder CODEC also can adopt independent parts, links to each other with bluetooth module by pcm interface.Described bluetooth module also is provided with the USB mouth that is attached thereto, and can directly link to each other with PC by this interface, allows the user can set in advance automatic Outgoing Number easily.
The present invention is transmitted help signal by Bluetooth wireless technology, need not complex drive mechanism, have volume little, carry and use advantages such as all very convenient.
Description of drawings
Fig. 1 is the hardware configuration schematic diagram of first embodiment of the invention;
Fig. 2 is the hardware configuration schematic diagram of another embodiment of the present invention.
Among the figure: 10-bluetooth module, 11-antenna, 12-microphone, 13-receiver, 14-CODEC, 15-help key, 16-key in danger, 17-USB mouth.
Embodiment
The invention will be further described below in conjunction with the drawings and specific embodiments.
Accompanying drawing has provided two indefiniteness embodiment of the present invention.In explaining process of the present invention, will omit detailed description to known function and structure.
As shown in Figure 1, wherein antenna 11 links to each other by the radio frequency interface of radio frequency line with bluetooth module 10, and this antenna can be selected the AT9520 product of Advanced Ceramic X company for use; Bluetooth module 10 is integrated coding decoder CODEC14, this part can adopt the BlueCore02-Flash module of CSR company to realize; Microphone 12 and receiver 13 are used to pick up/playing audio signal, also link to each other with CODEC14 by analog audio interface, and the analog signal that coding decoder CODEC14 converts to is carried out input and output; Help key 15 links to each other with bluetooth module 10 with key 16 in danger, is used for automatically transfering to the seek help number and the alarm call of storage in advance, and help key 15 also is used to control the coupling with mobile phone simultaneously.
Use the present invention to be divided into two kinds of situations:
First kind of situation is: when the end user runs into general danger and need seek help, only need click help key 15, this device just can be dialed the number of storage in advance automatically by the mobile phone that matches, and can realize conversing, to reach the purpose of being succoured;
Second kind of situation is: when the end user runs into special hazard and need report to the police secretly, only need click the key in danger 16 of lid protection, this device just can be by the mobile phone automatic dialing alarm phone that matches, so that the police in time succour.
Referring to Fig. 2, coding decoder CODEC14 is not integrated in 10 li of bluetooth modules as different from Example 1, but adopts independent parts, and links to each other with bluetooth module 10 by pcm interface.This unit can be selected the MC145483 phonetic codec chip of Motorola Inc. for use.Bluetooth module 10 also is provided with the USB mouth 17 that is attached thereto, and by this interface, the present invention can directly link to each other with PC, allows the user can set in advance automatic Outgoing Number easily.
The present invention sets in advance Outgoing Number can three kinds of modes:
First kind of mode is: by special-purpose software, write Outgoing Number in advance according to customer requirements when the dealer sells this product, can take same mode to carry out the number change.
The second way is: the present invention can provide the USB mouth, allows the user directly carry out the setting and the change of Outgoing Number in advance on PC.
The third mode is: the present invention can also directly use help key 15 and key in danger 16 to carry out Outgoing Number setting in advance.
