Description
Technical field
The utility model relates to a kind of supervisory control system, particularly a kind of system that the microwave equipment that is applied to mobile communications network is carried out remote monitoring.
Background technology
In mobile communications network, microwave equipment is mainly used in point-to-point digital microwave relaying.Some relay station is erected at and has inconvenient traffic, the isolated area of inclement condition.For these microwave equipments, managerial personnel can't in time obtain the operation information of equipment, grasp the alarm performance data of equipment, and the defective of equipment and fault also just can't in time be found, handle and be repaired, and this will have influence on the communication quality of communication network.
ETSI had released a kind of novel interactive mobile data services USSD based on the GSM mobile communications network in 1997, and so-called USSD (Unstructured Supplementary Service Data) is a unstructured supplementary data traffic.Its initial definition mainly provides basic supplementary service, as calling transfer, call barring etc., but along with the USSD standard enters the USSD phase2 stage, USSD uses and further expands now, can support the more non-constructed supplementary business of horn of plenty, for example stock lottery business, bank transfer, mobile e-business penny ante etc. also are applied in industry gradually.
As data transmission service, USSD and modes such as SMS, GPRS have a lot of similar places, but its oneself characteristics are arranged.
(1) transmission rate is lower
Under talking state, USSD and SMS use identical signaling channel, i.e. Dedicated Control Channel SDCCH (Stand-alone Dedicated Control Channel), and message transmission rate is approximately 600bps; But not during talking state, USSD uses quick assist control channel FACCH (FastAssociated Control Channel), and message transmission rate is approximately 1kbps, than SMS transmission rate height.GPRS data service and voice service shared channel, the highest theoretical value is 171.2kbps, actual transfer rate is greatly about 40kbps.
(2) response speed is fast, and interaction capabilities is strong
USSD keeps conversation to connect in conversation procedure always, and transparent channel is provided, and does not store forwarding; And SMS does not have session channel at the physical carrier layer, is a store-and-forward system, and the user finishes one query need carry out repeatedly conversation procedure.Because USSD keeps a conversation procedure in mutual, each data send and do not need to rebulid channel, and therefore with regard to the response time, USSD is faster than the response speed of short message.
(3) application cost is low
In USSD, SMS, these three kinds of modes of GPRS, the message transmission rate of GPRS still need be shared limited channel resource with speech business than higher, and for network and user, operating cost is all than higher.And USSD utilizes FACCH and SDCCH signaling channel to transmit, and expense is cheap, and cost is lower.
Compare with SMS, USSD not support terminal to the communication mode of terminal.
Based on these characteristics of USSD, be applied to microwave equipment is implemented remote monitoring, not only use cost is reasonable, and very necessary for the quality that guarantees communication.
The utility model content
The purpose of this utility model is to provide a kind of cost low, uses the system that USSD monitors remote microwave equipment.
Be the technical scheme that realizes that the purpose of this utility model adopts: a kind of system for monitoring remote microwave equipment, be connected with microwave equipment by signal, be characterized in, comprising:
Be used to read and transmit the monitor terminal of microwave equipment caution signal;
Be used to send and receive the USSD center module of the USSD message that comprises querying command or alarm signal;
Be used for monitoring center module that microwave equipment caution signal is inquired about and handled;
Described monitoring center module is connected with the USSD center module by signal; The USSD center module is connected with monitoring terminal by signal; Monitor terminal is connected with microwave equipment by signal.
More specifically, described monitoring center module is connected with the USSD center module by signal by Internet.
Described USSD center module is connected with monitoring terminal by signal by the GSM network.
Described monitor terminal and microwave equipment signal one to one are connected.
Described monitor terminal is connected to form by W77LE58 microprocessor, GSM modulator-demodulator and power module.
Described GSM modulator-demodulator is meant TC35i.
System for monitoring remote microwave equipment of the present utility model is work like this: monitoring center module sends querying command to each monitor terminal in turn by the USSD center module, after monitor terminal receives effective USSD message from the GSM network, extraction is encapsulated in the order in the USSD message packets, obtain facility information according to order from microwave equipment alarm data interface, handle the back according to the self-defining communications protocol format of system, be encapsulated in the USSD message data field, utilize the AT order to send to the GSM network, through turning back to monitoring center module after GSM network and the USSD center module by the GSM modulator-demodulator.Like this, monitoring center module can be monitored the ruuning situation of each microwave equipment, the alarm event of display device.
The utility model with respect to the major advantage of prior art with effect is: 1, compare with wire transmission mode, the wireless data transmission mode has more flexible characteristic, and that the USSD mode has more response speed is fast, the characteristics that interaction capabilities is strong, therefore, use the USSD pattern just can realize monitoring to remote microwave equipment, than wired monitoring mode more flexibly and the scope of communicating by letter expand greatly; 2, using the USSD pattern to carry out remote monitoring, can make full use of the existing wireless network resource of operator, need not to set up special wire transmission network, is not very big situation for amount of communication data, greatly reduces monitoring cost.
