Detailed description of the invention
By the following description to embodiment, will more contribute to public understanding this utility model, but Specific embodiment given by applicant can't be considered as this utility model technical side The restriction of case, any definition to parts or technical characteristic is changed and/or overall structure is made shape Formula and immaterial conversion is regarded as the protection domain that the technical solution of the utility model is limited.
On-site wireless Wi-Fi voice communication device as shown in Figures 1 to 4, including a central point, Being provided with ip voice server on central point, ip voice server is connected with router, passes through Wi-Fi Wireless mode is connected with ip voice system and relay point, is provided with for realizing wireless communication in relay point The wireless repeater of number long-distance transmissions, command car control centre is connected with central point by relay point, Wireless repeater includes the wireless receiving module for receiving signal and for launching wireless of signal Penetrate module, by known wired or wireless relation between wireless receiving module and wireless transmitter module Being connected with each other, or be connected with each other by control chip, the effect of control chip is to wireless receiving The signal that module receives processes, it may be judged whether sends signal and instruction is accordingly passed to Wireless transmitter module, the outside of wireless interrupt module 1 is provided with a shielding shell, shields shell The metal sidewall 2 arranged including circumference encapsulation, one end of shielding shell is provided with nonmetal cover plate 3, screen The other end covering shell is leading-out terminal, and the effect of leading-out terminal is to draw holding wire, and wireless module sets Have one for receive launch signal antenna 4, the generation end of antenna 4 is towards nonmetal cover plate direction. In the present embodiment, antenna 4 is made up of two connecting rods, and antenna is overall in " L " font, Qi Zhongyi Individual connecting rod is main running signal bar 41, and main running signal bar 41 is perpendicular to the body of wireless interrupt module 1, Another connecting rod 42 is signal lever tip, and direction parallel with the body of wireless interrupt module 1 is dorsad Nonmetal cover plate 3 side, main running signal bar 41 launches signal through the nonmetal cover plate 3 in front.
In the present embodiment, on-site wireless WIFI voice communication device uses 12V battery to power, Control chamber continuous working period is not less than 3 hours, mainly ip voice system, central point, commander Speech communication between car control centre, relay point, voice point (3G network).On-site wireless The main characteristics function of WIFI voice communication device is as follows: 1, wifi base-station environment: ensure that 6 In the case of road above language terminal is online, voice communication is normal, clear.The external 10DB in base station Gain omni-directional antenna, coverage is radius more than 200 meters;2, GSM network interface: voice System has access to GSM gateway device, it is provided that GSM gateway interface.3, IP network phone connects Mouthful: operator can add voice system by IP network telephone set;4, FXO interface: phone Line interface, outside line can be by entering voice system after dialing this telephone number;5, network interface: Computer to access server host can be passed through, configure;6, equipment reserves Mike and speaker interface, Interface is 6.5 standard audio jack of standard.Microphone interface can be accessed by powerful wireless Mike's equipment, Speaker interface can be accessed by large-scale audio external play equipment;7, need between Liang Tai and more than two voice systems Time to be connected, the sub-member in every amoyese system for electrical teaching all can reach assigned number enter the other side by dialling Voice system.In other embodiments, wireless repeater also includes stand-by power supply, stand-by power supply It is preferably lithium battery.When DC modular converter is to electricity consumption loop power supply, stand-by power supply is in storage Standby state, when DC modular converter does not gives electricity consumption loop power supply, stand-by power supply supplies to electricity consumption loop Electricity.
The operation principle of wireless relay is: wireless receiving module, the signal received, passes to control Coremaking sheet, the signal that control chip analyzing and processing wireless receiving module receives, if currently received Burst of data is to meet the data of the form of regulation in SOLONWEB agreement, and control chip judges The value (ID_COUNT) of the source (ID_FROM) of data and the enumerator of data (these all In SOLONWEB agreement, have regulation), so that it is determined that before currently received data either with or without Receiving, (ID_FROM value and ID_COUNT value were with receiving before without receiving In serial data, corresponding value differs), just this secondary data is sent by wireless sending module, If received, (ID_FROM and ID_COUNT value was with corresponding in the serial data that receives before Value is identical) the most do not send this secondary data.
In actual applications, wireless repeater uses shielding shell to come wireless module two end signal real Now shielding, the body of wireless repeater is arranged in shielding shell, by the sky set on wireless module Line 4 receives signal.On the one hand this shielding shell disclosure satisfy that the requirement that rescue command is on-the-spot, another Individual critically important aspect is exactly the scattering degree that can shield wireless transmitter module towards both sides, it is ensured that nothing Line transmitter module is when certain receiver module dead ahead, and this receiver module signal strength values is the strongest, its The signal strength values of both sides receiver module and its difference are relatively big, under some complex electromagnetic environments Rescue command is on-the-spot, and interference ratio is more serious, be still capable of to equipment accurate, stable, can By location.
Certainly, this utility model can also have other various embodiments, without departing substantially from this utility model In the case of spirit and essence thereof, those of ordinary skill in the art can do according to this utility model Go out various corresponding change and deformation, but these change accordingly and deformation all should belong to this practicality newly Scope of the claims appended by type.
