Below in conjunction with specific embodiment such scheme is further specified.Should be understood that these embodiment are used to the present invention is described and are not limited to limit scope of the present invention.The implementation condition that adopts among the embodiment can be done further adjustment according to the condition of concrete producer, and not marked implementation condition is generally the conventional condition of using.
Embodiment
As shown in Figure 1; This is wireless multichannel explanation device and system; It comprises transmitter 11, recipient 21; Wherein transmitter comprises mission controller 12, wireless transmitter module 13, FM broadcasting module 14 and data memory module 15, and recipient comprises reception controller 22, frequency range is provided with module 24, wireless communication module 23 and frequency modulation and accepts module 25.
The wireless transmitter module of transmitter receives the wireless request instruction of recipient, starts the emission of FM broadcasting, and the frequency information that returns the frequency modulation emission is given recipient; Recipient receives the frequency information of wireless transmitter module, starts frequency range and module is set the FM broadcasting receive frequency is set automatically begins to answer the explanation content; The state information of transmitter Fixed Time Interval inquiry recipient; Add up to zero when receiving the recipient regenerating condition, then stop the FM signal emission.
Wireless transmitter module is responsible for sending instruction through wireless channel; The FM broadcasting module is responsible for broadcasting through the transmission channel data; Data memory module is used for storage explanation content; Accepting controller is used to listen request and feedback request information; Frequency range is provided with module and is used for being provided with automatically the FM broadcasting receive frequency; Frequency modulation is accepted module and is used for accepting the explanation content according to the FM broadcasting receive frequency is set.
Recipient uses unique identification mark indicating self, is convenient to the identification of transmitter to equipment; The ID authentication list and the blacklist that comprise recipient in the transmitter.Transmitter can be supported the FM broadcasting emission of a plurality of channels simultaneously, and recipient matees automatically and the suitable frequency of accepting is set.Wireless telecommunications between transmitter and the recipient can be supported short-distance wireless communication patterns such as bluetooth, Wifi, infrared or less radio-frequency.
When broadcasting, the mode of multicasting is following:
1) wireless module of transmitter receives the wireless request instruction of recipient, starts the emission of FM broadcasting, and the frequency information that returns the frequency modulation emission is given recipient;
2) recipient receives the frequency information of transmitter module, the FM broadcasting receive frequency is set automatically begins to answer;
3) state information of transmitter Fixed Time Interval inquiry recipient, as receive the recipient regenerating condition and add up to zero, the FM signal emission then stopped.Wherein transmitter can send broadcast data and wait-for-response in the zone; When not responding, stop the FM signal emission; Otherwise continuation broadcast data.
When the wireless module of transmitter receives the wireless request instruction of recipient; The frequency of the current frequency range of feedback is given recipient from a plurality of frequency ranges; When the time difference of time that starts frequency range and admission confirm surpassed settings, transmitter started new frequency and goes on the air; If the frequency range formation reaches maximum, then return the frequency minimum at interval start-up time automatically with inserting request time.
The mission controller of transmitter is connected with content storage devices, the audio, video data that storage device for storing is play; The storage device of transmitter can be connected with server, accepts the content-data of service device transmission or the content-data of buffer server; The storage device of transmitter can be stored the multiple segment data broadcasted content, can independent broadcast on different frequency range.
Illustrate below, the explanation of this wireless multichannel introduction system, content comprises divides into 2 sections, and first section introducing system, the 2nd section are introduced equipment; Other comprises Chinese, two kinds of explanations of Japanese speech.In the USB dish, deposit.Recipient comprises 2 mode switchs, front and back page-turning button.Reflector comprises 8 frequency modulation channels, is divided into 2 groups, respectively the above-mentioned 4 sections contents of loop play.
When carrying out the multicasting explanation, begin to start reflector, reflector is launched wireless interrogated in predetermined zone.When certain or certain several receivers responded the wireless interrogated request, reflector activated wireless transmitter module through mission controller; Otherwise when not having recipient response inquiry request in the blanking time of presetting, reflector stops the FM signal emission, waits for next inquiry cycle continuation inquiry.
When the request of receiver response wireless interrogated, whether content and frequency that reflector is monitored according to the receiver needs are checked to have and have been launched corresponding frequency range and content.When having corresponding frequency range and content, corresponding frequency range.Do not exceed blanking time during scope when the time that starts frequency range, distribute to start corresponding new frequency range, mission controller calls FM broadcasting module 14 radio broadcasting related contents.At this moment, the reception controller 22 of recipient is provided with module 24 according to frequency range through frequency range the frequency that frequency modulation is accepted module 25 is set automatically, receives controller 22 control frequency modulation then and accepts module 25 and answer related content through wireless communication module 23.
Here recipient can be several kinds, and recipient can be answered the introducing system of first section Chinese explanation speech, also can answer the equipment of introducing of the 2nd section Chinese explanation speech; Even can answer the introducing system that speech explained in first section Japanese, also can answer the equipment of introducing of the 2nd section Japanese explanation speech.These different broadcast contents are broadcasted through different FM broadcasting modules 14.Different FM broadcasting modules 14 can adopt different frequency ranges to broadcast.Preferably, FM broadcasting module 14 has 8, can be divided into two groups, every group of above-mentioned 4 sections contents of difference loop play.
When launching corresponding frequency range not enabled, whether the mission controller of reflector is searched frequency range through FM broadcasting module 14 full, judges promptly whether the frequency range formation reaches preset maximum.When frequency range less than the time, through starting new frequency range, accept the request of recipient again.When frequency range expires, then return the frequency minimum at interval start-up time automatically with inserting request time, this frequency is broadcasted as the new frequency range of launching.
Exceed blanking time during scope when the time that starts frequency range, whether the mission controller of transmitter is searched frequency range through FM broadcasting module 14 full, judges promptly whether the frequency range formation reaches preset maximum.When frequency range less than the time, through starting new frequency range, accept the request of recipient again.When frequency range expires, then return the frequency minimum at interval start-up time automatically with inserting request time, this frequency is broadcasted as the new frequency range of launching.
Above-mentioned instance only is explanation technical conceive of the present invention and characteristics, and its purpose is to let the people who is familiar with this technology can understand content of the present invention and enforcement according to this, can not limit protection scope of the present invention with this.All equivalent transformations that spirit is done according to the present invention or modification all should be encompassed within protection scope of the present invention.
