The utility model content
In order to overcome aforesaid problem, the utility model provides a kind of data communication server, the data that it can send by mobile device under the wireless mode received well, and the data flow relaying is transmitted to other nodes such as main control server by wired mode.
The technical solution adopted in the utility model is: a kind of digital communications services device, be provided with first interface circuit that is used for transfer of data between data sending terminal and this digital communications services device, and second interface circuit that is used for transfer of data between digital communications services device and the main control server, wherein first interface circuit comprises modulator-demodulator.
Further, this data communication server also comprises telephone exchange, and it is connected with this digital communications services device by the operation control interface.
Preferably, this first interface circuit comprises the radio receiver that is connected with this modulator-demodulator.
Preferably, this second interface circuit comprises network interface card, realizes communicating by letter by between twisted-pair feeder and the main control server.
Preferably, this second interface circuit comprises the digital cable modulator-demodulator, realizes communicating by letter by between coaxial cable and the main control server.
Preferably, this second interface circuit comprises digital subscriber link modem, realizes communicating by letter by between telephone wire and the main control server.
Preferably, this second interface circuit comprises wireless network card.
In above-mentioned technical scheme, because transmitting, the data of sending and receiving end all adopt a modulator-demodulator to finish, therefore simplified equipment, reduced cost, make maintenance be more prone to.Simultaneously, the digital communications services device has alleviated the pressure of main control server, makes data in time to be handled, and provides condition for ensureing underground work safety, can also realize multiple conversation form by the telephone exchange function in addition, provide convenience for the staff communicates with each other.
Description of drawings
Fig. 1 is a schematic block diagram of the present utility model;
Fig. 2 a is the part of the circuit theory diagrams of an embodiment;
Fig. 2 b is another part of the circuit theory diagrams of the foregoing description, constitutes the complete circuit theory diagrams of this embodiment jointly with Fig. 1 a;
Embodiment
The utility model is described in further detail below in conjunction with the drawings and specific embodiments.
The utility model provides a kind of data communication server, and the data that its energy received well is gathered down are forwarded to miscellaneous equipment with these data relayings, and can realize the telephone exchange function.
As shown in Figure 1, and, under coal mine, there is the several data collecting device, comprises most important gas monitor equipment, other the transducer that detects dust concentration, temperature, humidity, air pressure, wind speed and noise or the like in addition referring to Fig. 2 a and Fig. 2 b.After these equipment collect data, need to send it to ground sometimes,, can adopt wired or wireless mode according to the difference of equipment.For example for gas monitor equipment, the firedamp sensor that fixing firedamp sensor is arranged or push ahead along with working face, it can adopt cable that the data of collecting are sent earthward, be worn on underground work personnel portable firedamp sensor on one's body in addition, the mode of its transmission data is wireless mode often.The data transfer mode of other underground data measuring device is also identical substantially.All these Data Sources can adopt equipment separately that data are sent, but preferably these data are combined, and send by an equipment, to simplify R-T unit.Preferred scheme is to adopt a control chip (for example single-chip microcomputer or embedded chip etc.) to receive these data, and send with analog form by a modulator-demodulator, can adopt wireless launcher to send, can't propagate into the occasion on ground at wireless signal, also can adopt wired mode to send.In order to distinguish Data Source, can be each device numbering, in the data of transmission, carry this numbering, multiplex modes such as use frequency division multiplexing are sent data.This just requires the receiving terminal can be according to the difference of transmitting terminal, receives and recovers these data.In Fig. 1, modulator-demodulator is used for the data that demodulation is sent by transmitting terminal, and when data sent with wireless mode, this data communication server comprised that also a corresponding radio receiver receives it.Data after the demodulation are sent in the digital communications services device, and this server is according to the entrained coded message specified data of data source, and it is carried out taxonomic revision and sends in the main control server.The digital communications services device is except handling wireless communication data, also can transfer data to each node, control monitor shooting angle of for example main control server being sent and direction command transfer are given the relevant device control chip, and when causing danger, the voice signal of notifying the personnel in the pit to withdraw sends to the control chip of loud speaker etc.
In a specific embodiment, interconnected by twisted-pair feeder between digital communications services device and the main control server via network interface card.For example, receive on the switch or hub of same local area network (LAN).Speed and quality in order to guarantee transfer of data can also adopt optical interface device and optical fiber.This mode relatively is fit to digital communications services device and main control server apart from switch all more in short-term, for example less than 100 meters.When distance between them is big, can adopt digital cable modulator-demodulator (cable modem), realize communicating by letter by between coaxial cable and the main control server, perhaps adopt Digital Subscriber Line (DSL) modulator-demodulator, realize communicating by letter by between telephone wire and the main control server.The advantage of coaxial cable is that speed is fast, but lay cables is cumbersome, and the DSL mode is simple in the place wiring that telephone wire is arranged, but limited bandwidth can be selected suitable execution mode in actual applications as required.In addition, also can adopt wireless mode to carry out data communication, for example adopt Bluetooth technology, this mode is convenient and swift, but needs to lay base station receiver equipment.
In another specific embodiment, this data communication server also can comprise a telephone exchange, and the digital communications services device is connected with its operation control interface, and it is carried out programming Control.This telephone exchange function with in each interphone, external call, the mine fixedly the communication that is equipped with of mobile working unit link together, according to different call request, by program control realization one to one, the conversation of one-to-many, many-one, multi-to-multi.In one embodiment, if each working node of ground has all been realized computer networking, also can not need telephone exchange, and realize network IP telephone function by the program on the digital communications services device, each staff just can realize conversation by earphone like this.
Data communication server of the present utility model can adopt in the colliery, also needs the occasion of the several data that integrated treatment gathers applicable to other.The utility model is collected data such as gas density, dust concentration, temperature, humidity, air pressure, wind speed and noise by modulator-demodulator and receiving system, and with its be transmitted to main control server collection, analyze, show, backup etc., and can give other node with the data forwarding of each node, for each node provides the active data service, and the voice service of multi-way call.
Those skilled in the art are to be understood that; the disclosed specific embodiment of the utility model is not that the utility model is carried out any restriction; but in order to make the those skilled in the art more clearly understand the utility model, protection range of the present utility model is only defined by appended claims.
