Abstract
The utility model relates to a dual-band vehicle-mounted interphone with two operating systems, mainly comprising a band display 1, a band display 2, a CPU controller and a keyboard controller. The band display 1 and band display 2 are both electrically connected with the CPU controller through electric wires. The keyboard controller is electrically connected with the CPU controller through an electric wire. Compared with the prior art, the dual-band vehicle-mounted interphone is allowed to receive two same bands or different bands at the same time to work, can realize the communication of many people and high practicability, the bands of the dual-band vehicle-mounted interphone are not restricted, and the working modes of the dual-band vehicle-mounted interphone are separated from each other and independent of each other.
Description
Technical field
The utility model relates to vehicle-mounted intercom, and what be specifically related to is a kind of vehicle-mounted intercom of two-band with two operating systems.
Background technology
The vehicle-mounted intercom of radio is a kind of wireless communication tool in the mobile call, can many people exchange each other simultaneously because of having, and makes many people can listen to same people simultaneously and speaks, instant in real time communication, the effect of getting ready to go into action in hundreds; It is economical and practical, and operation cost is low, does not expend cost of the phone call, and is easy to use; Particularly handling urgent accident or carrying out in the dispatch control, its effect is that other communication tool can not substitute.
At present; Existing most vehicle-mounted intercom has only a working frequency range job; Single frequency band work like very high frequency(VHF) VHF (30-300MHz) or superfrequency UHF (300-3000 MHz); In use listening to frequency range has limitation on the one hand for it, and single frequency band also has the generation of phenomenons such as noise, audio mixing on the other hand.
The utility model content
The purpose of the utility model is the deficiency to above technology, and a kind of two vehicle-mounted intercoms of two-band that separate independent operation that utilize a talk back equipment may command to realize two frequency ranges are provided.
The utility model is realized through following technical scheme: the vehicle-mounted intercom of a kind of two-band of two operating systems, mainly form by frequency range display one, frequency range display two, cpu controller and KBC.
Said frequency range display one and frequency range display two electrically connect through electric wire with cpu controller respectively, and KBC and cpu controller electrically connect through electric wire.
Cpu controller is used for channel, the wavelength band of control frequency setting effectively, numeral and character name, and utilizes described KBC to carry out selectivity and regulate.
Said frequency range display one can show different frequency range with frequency range display two, also can show similar frequency bands; This two n segment display n can clearly come channel, the wavelength band of display frequency setting, numeral and character name with two row.
The beneficial effect of the utility model embodies and is: compared with prior art, the utility model intercom can easily allow to receive two similar frequency bands or different frequency range work simultaneously, and its mode of operation is separated independent operation; Do not disturb mutually; Many people's conversations, frequency range does not receive limitation, and is practical.
Description of drawings
Below in conjunction with accompanying drawing the utility model is carried out detailed explanation;
Fig. 1 is the utility model block diagram.
Classify among the figure concrete title of each sign down as: 1 KBC, 2 cpu controllers, 3 frequency range displays one, 4 frequency range displays two.
Embodiment
As shown in Figure 1, the vehicle-mounted intercom of a kind of two-band of two operating systems mainly is made up of frequency range display 1, frequency range display 24, cpu controller 2 and KBC 1.
Said frequency range display 1 and frequency range display 24 electrically connect through electric wire with cpu controller 2 respectively, and KBC 1 and cpu controller 2 electrically connect through electric wire.
Cpu controller 2 is used for channel, the wavelength band of control frequency setting effectively, numeral and character name, and utilizes described KBC 1 to carry out selectivity and regulate.
Said frequency range display 1 can show different frequency range with frequency range display 24, also can show similar frequency bands; This two n segment display n can clearly come channel, the wavelength band of display frequency setting, numeral and character name with two row.
Claims (3)
1. the vehicle-mounted intercom of two-band of two operating systems is characterized in that: be made up of frequency range display one, frequency range display two, cpu controller and KBC; Said frequency range display one and frequency range display two electrically connect through electric wire with cpu controller respectively, and KBC and cpu controller electrically connect through electric wire.
2. the vehicle-mounted intercom of the two-band of a kind of two operating systems according to claim 1; It is characterized in that: cpu controller is used for channel, the wavelength band of control frequency setting effectively, numeral and character name, and utilizes described KBC to carry out selectivity and regulate.
3. the vehicle-mounted intercom of the two-band of a kind of two operating systems according to claim 1 is characterized in that: said frequency range display one can show different frequency range with frequency range display two, also can show similar frequency bands.
