Compared with the prior art, the output signal of the utility model can be a CW signal or a modulated signal, a plurality of mobile network forms can be supported by only modifying the program of the signal source, and the indoor communication transmission device has small equipment, no panel design and convenient operation and is convenient for engineering application; parameter control is carried out through computer connection, a computer can be disconnected after connection, and the equipment continues to work; and the indoor communication transmission device is provided with a battery and can continuously work for more than five hours.
Description
Technical field
The utility model relates to transmitter, particularly relates to a kind of indoor communications emitter.
Background technology
The custom of using mobile phone along with the development and the people of mobile communication changes, use more and more universal at indoor use mobile phone and card of surfing Internet, DoCoMo once did a statistics, present indoor telephone traffic accounts for more than 70% of total traffic, along with popularizing of net book, believe that the ratio regular meeting of indoor telephone traffic is higher.Therefore indoor distributed system more and more obtains paying attention to, and the quality of indoor distributed system quality also will directly have influence on the income of operator.The construction of indoor distributed system in the past is not a standard very, and planning is gone to toward not carrying out simulation test; And the extensive use of CDMA technology is bad if indoor covering is planned, just will produce bigger influence to big net, perhaps we can say to be exactly an interference source of big net.
Summary of the invention
Technical problem to be solved in the utility model is exactly to provide a kind of indoor communications emitter for the defective that overcomes above-mentioned prior art existence.
The purpose of this utility model can be achieved through the following technical solutions: a kind of indoor communications emitter, it is characterized in that, comprise power module, control module, signal source, power amplifier and communication interface, described power module is connected with control module, signal source, power amplifier, described control module is connected with communication interface, signal source, and described signal source is connected with power amplifier.
The utility model also comprises an external battery, and described power module is provided with a 220V power interface, and described external battery is connected with power module 220V power interface.
Described communication interface is a RS-232 interface.
Compared with prior art, the utlity model has following advantage:
1, output signal can be that the CW signal also can be the signal of band modulation, only needs just can support multiple mobile network's standard by the program of revising signal source;
2, equipment is small and exquisite, and no panel designs is easy and simple to handle, is convenient to engineering and uses;
3, parameter control is carried out in the computer connection, computer can be disconnected after the connection, and equipment works on;
4, be furnished with battery, sustainable work is more than 5 hours.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
Embodiment
Below in conjunction with accompanying drawing the utility model is described further.
As shown in Figure 1, a kind of indoor communications emitter, comprise power module 1, control module 2, signal source 3, power amplifier 4 and communication interface 5, described power module 1 is connected with control module 2, signal source 3, power amplifier 4, described control module 2 is connected with communication interface 5, signal source 3, and described signal source 3 is connected with power amplifier 4.
The utility model also comprises an external battery, and described power module is provided with a 220V power interface, and described external battery is connected with power module 220V power interface; Described communication interface is a RS-232 interface.
The utility model is used for the indoor covering system engineering construction, and real anolog base station transmits, and can not only obtain field intensity information in the test, can also obtain carrier/interface ratio information, can reflect the situation of indoor distributed system truly, avoids big net is produced interference.
Signal source: adopting DSP and FPGA technology, can produce the base station signal of various standards according to user's demand, can be the CW signal, also can be that real base station transmits, i.e. signal after the modulation;
Power amplifier: be used for power amplification, the output of different capacity is provided;
Power module: equipment built-in power module, give each module for power supply, external interface has only a 220V alternating current;
Control circuit: control each module according to customer requirements, make to be output as the signal that the user needs.
The utility model utilizes Digital Signal Processing to produce the base station signal of various mobile communication, and base station signal by power amplifier, is reached the power output of actual requirement of engineering; Also can be by RS-232 and dataphone, in-house facility is not controlled button and display screen, and all controls are by computer program control, in case behind the equipment, can disconnect and the linking of computer, are convenient to engineering and use.
