Description
Technical field
The present invention relates to field of communication technology more particularly to a kind of transmission methods and system of character emergency communication machine.
Background technique
Traditional emergency command communication is mainly based upon public mobile network, conventional intercom or three kinds of conventional digital cluster
Mode.Mode based on public mobile phone mobile network does not support group call, can not form the collaborative work of team, group, and exhale
It makes nonpreemption limit, can only be waited when Called Subscriber is in call, may be delayed and link up the best opportunity;Based on conventional intercom
Mode cannot achieve wide-area communication, communication distance is limited, does not support to interconnect with telephone or satellite communication, cannot achieve remote
Distance communication;And conventional digital trunked communication system includes the large scale equipments such as base station, controller, this kind of equipment volume is big, weight
Greatly, it carries and transports and is very inconvenient;Conventional digital cluster is communicated using digital junction mode, and networking is inflexible.
Summary of the invention
It is in view of the deficiencies in the prior art or insufficient, the technical problems to be solved by the present invention are: providing a kind of word
Emergency communication machine is accorded with, it is small in size, it can guarantee the most basic communication between mobile phone.
To achieve the goals above, the technical scheme adopted by the invention is as follows providing a kind of transmission side of character emergency communication machine
Method includes the following steps:
Step 1: character emergency communication machine APPS application program is installed on mobile phone, opens this application program;
Step 2: mobile phone passes through the embedded server link in Wifi and character emergency communication machine;
Step 3: realize that character network chain connects by dedicated RF module between character emergency communication machine;
Step 4: character emergency communication machine is linked with the APP application program in mobile phone;Communication linkage is carried out between mobile phone.
As a further improvement of the present invention, embedded server provides software platform in the step 2, completes data
Transmission specification, data are packaged transmitting-receiving caching, while the parallel link control function for completing RF module, complete wireless transmission arbitration,
Channel data manages control function.
As a further improvement of the present invention, the dedicated RF module of the step 3 character emergency communication machine usually all in
Receptive pattern once discovery sends channel sky, and allows to send, just sends data according to the wireless arbitration scheme being set
Block, the same moment, only one communication equipment was in transmission state.
As a further improvement of the present invention, the embedded server uses ARM cortex SOC chip.
As a further improvement of the present invention, the dedicated RF module uses digital modulation /demodulation and high speed RF-DAC,
And channel frequency supports UHF/VHF until short wave channel, numeric code rate is less than 300bps.
As a further improvement of the present invention, the additional RF power amplifier of the character emergency communication machine.
As a further improvement of the present invention, the character emergency communication machine and charger baby are integrated in a machine box.
A kind of character emergency communication machine system, including more character emergency communication machines, every character emergency communication machine include
WiFi module, embedded server, RF link controller, RF module.
The beneficial effects of the present invention are: character emergency communication machine of the invention is the signal covering in not cellular base station
Under, continuation is chained up mobile phone with character communication net, forms group, guarantees to know respective positions between group member, respective
Simple characters response, and keep punctual and duly communication.In times of crisis or remote districts guarantee most basic communication linkage.
Detailed description of the invention
Fig. 1 is character emergency communication machine frame figure provided by the invention;
Fig. 2 is pictorial block diagram illustration of the invention.
Specific embodiment
The present invention is further described for explanation and specific embodiment with reference to the accompanying drawing.
As shown in Figure 1, the present invention provides a kind of character emergency communication method and system, the specific steps are as follows:
Character emergency communication machine APPs application program is installed on mobile phone;
Mobile phone passes through the embedded server link in WiFi and character emergency communication machine;Lead between character emergency communication machine
It crosses dedicated RF module and realizes that character network chain connects;
User be using interface similar wechat window, can typewrite symbol, transmission character, can recorde whole and communicated
Journey.
Communication equipment and embedded server guarantee the character data link of RF channel, keep the position for updating each node in group
It sets and situation.
User is known that the case where other group members in group at any time.
WiFi module is interacted with cell phone application S, completes human-computer dialogue, keeps communication interface.WiFi module is selected in the market
Standard chips are stabilized, guarantee compatibility.
Embedded server provides software platform, completes data transmission specification, and data are packaged the function of transmitting-receiving caching.Simultaneously
The parallel link control function for completing RF module completes wireless transmission arbitration, the control functions such as channel data management.Embedded clothes
Business device selects ARM cortex SOC chip, the AP+CP processor being equivalent in phone solution
Dedicated RF module, the RF module of each character emergency communication machine is usually all in receptive pattern, once discovery is sent
Channel is empty, and allows to send, just according to the wireless arbitration scheme transmission data block being set, the same moment only one
Communication equipment is in transmission state.Implementation uses digital modulation /demodulation and high speed RF-DAC.RF channel frequency supports UHF/
VHF is less than 300bps until short wave channel, numeric code rate, and transmission range is determined that each communication equipment can by different channel modules
To be that other transmitting stations relay relay according to packet header specification.Common position, the emergency informations such as state automatically keep Share update.
The RF module of each communication equipment supports additional RF power amplifier, thus supports the application on car and boat.
Character emergency communication machine and charger baby are integrated in a machine box, and guaranteeing can be 50 hour with continuous work in emergency
More than.
