The subject matter that existing power communication private network exists has: the network configuration of (1), communication network is relatively weaker: the power communication backbone network is generally optical fiber communication or digital microwave telecommunication at present, some areas still do not have condition to set up optical fiber self-healing looped network, the part of links mesh network often is subjected to the influence of various external force factors, and its loaded service can not normally be moved; In case remote motion signal breaks down in this case, can't find immediately and share the faulty line business by circuitous circuit; (2), the primary transmission off-capacity: power private network communication, except that building up the fiber optic circuit that puts into operation in recent years, old trunk circuit capacity generally has only 34Mb/S, minority is 140Mb/S and 155Mb/S, has restricted the developing of broadband new business; (3), communication system falls behind, the trunk circuit extended active duty is serious: some areas main line microwave circuit remains the transmission system based on PDH, has much moved more than 10 year, is badly in need of updating.Prefectures and cities city Netcom letter is built slowly; (4), various places development pole imbalance: various places economic development level difference, on power communication, also show as the development pole imbalance, some areas, unit have realized digitlization, fiberize looped network, having the ability provides communication service to society; The most basic dispatching telephone of the remote transformer station in some place even company can not guarantee.At present, research at remote motion signal mainly concentrates on the accident analysis of signal and the detecting instrument aspect of remote motion signal, as the portable telecontrol channel fault analysis instrument of YJT-100 type, power remote tester XG2052, BTS-1000 portable power telemechanical test macro or the like.These instruments otherwise can only be separately to the monitoring of remote motion signal, or can only haul oneself willingly into separately, but simultaneously as yet not deeply the correlative study of the monitoring of remote motion signal and self-operation system.
Summary of the invention
The purpose of this utility model provides a kind ofly to be had power communication remote motion signal simultaneously and detects and haul oneself willingly into function, reliability and safe, real-time power communication remote motion signal monitoring and haul oneself willingly into instrument.
The purpose of this utility model is achieved in that the utility model comprises by front panel, rear board, left panel, right panel, the casing that top panel and bottom panel are formed, the both sides of plate are equipped with handle in front, on the plate mains switch is installed in front, power supply indicator, reset switch, the working station indicator and the indicator light of communicating by letter, on the plate telephony interface is installed in the back, fuse holder and supply socket, be processed with fan hole on the plate in the back, feature is on the plate automatic/hand change over switch and download/function switch to be installed also in front, near-end input/output pulse coded modulation (PCM) leased-line interface also is installed on the plate in the back, far-end input/output pulse coded modulation leased-line interface and download interface, central control module is installed in casing, carrier detection module, the electric power modem module, public telephone network (PSTN) modem module, remote update module and relay module, wherein the input of the near-end of near-end input/output pulse coded modulation leased-line interface can be connected with the signal input part of electric power modem module and the far-end output of far-end input/output pulse coded modulation leased-line interface respectively by relay module, the far-end input of the signal output part of electric power modem module and far-end input/output pulse coded modulation leased-line interface all can be connected with the near-end output of near-end input/output pulse coded modulation leased-line interface respectively by relay module, the far-end input of the input termination far-end input/output pulse coded modulation leased-line interface of carrier detection module, the carrier signal input of the output termination central control module of carrier detection module, the electric power modem module, the public telephone network modem module adopts two-way the connection with central control module respectively with the remote update module, and the control signal output ends of central control module is succeeded the control input end of electrical appliance module.
After power communication remote motion signal detected and hauls oneself willingly into instrument and power on, its near-end input linked to each other by relay module with the far-end input with far-end output, near-end output, and carrier detection module begins to detect the carrier wave of remote end input signal; When carrier detection module detected less than carrier wave, it notified central control module at once, and central control module sends the alarm indication at once, starts dial-up program then; If central control module is set up with the central control module of opposite end and communicated by letter, it starts the authentication program at once; If the identity of central control module obtains confirming that it changes the communication pattern indication at once, and the control relay module, make the near-end input link to each other with the input of electric power modem module, near-end output links to each other with the output of electric power modem module; The power modulation demodulation module is to the near end input signal demodulation then, central control module is encrypted demodulating data, public telephone network modulation module is modulated enciphered data then, delivers to the public telephone network modulation module of opposite end at last through public telephone network; Meanwhile, public telephone network modulation module is carried out demodulation to received signal, obtains enciphered data; Enciphered data is delivered to central control module, and by its deciphering, last power modulation demodulation module is modulated data decryption, and modulation signal is sent to the near-end lead-out terminal.
The utility model has been finished power communication remote motion signal first and has been detected and hauled oneself willingly into function.Electric power system is the blood of whole national economy, and power communication, control are again the cores of electric power system, thereby it has proposed very high requirement to power communication remote motion signal.Because the running environment complexity of power communication, power communication remote motion signal is subjected to the interference of various natures and human factor, and the safe operation of this electric power system has constituted very big threat.The utility model is on the basis that carrier signal is detected, and can analyze the fault of remote motion signal circuit.In case it judges that there is fault in remote motion signal circuit, will start dial-up program, finish the transmission of remote motion signal by public telephone network, guarantee the high reliability of power communication remote motion signal.Therefore the utlity model has and have the power communication remote motion signal detection simultaneously and haul oneself willingly into function, reliability and advantage safe, real-time, that can shorten power communication and control appliance technology innovation time, reduction power communication and control attendant workload.
