Embodiment
At present the dispatch automated system passage comprises three kinds of analog channel, digital channel and network channels.As Fig. 1, the utility model comprises analog channel detection module, digital channel detection module and network channel detection module, and computing machine is imported in the output of three detection modules behind change-over circuit; Specify the utility model below in conjunction with accompanying drawing.
The analog channel of dispatch automated system, it is the four-wire circuit of pulse code modulation (PCM) PCM in the optical fiber and digital communication facilities, its path frequency band is 300 ~ 3400Hz, the telemechanical transmission band is more than the 2600Hz, two of 3000 ± 150Hz frequencies normally, correspondence is provided with the 2600Hz Hi-pass filter, simultaneously because the telemechanical transmission band is more than the 2600Hz, select the 2400Hz low-pass filter for use, as the loopback of analog channel detection module of the present invention; The main website end is sent from descending check point with the sinusoidal wave detection signal of 800Hz, can pass through the 2400Hz low-pass filter smoothly, measures relatively with dual trace oscilloscope to up check point, can judge the quality of passage very soon.The setting of analog channel detection module comes down to utilize the 2400Hz low-pass filter in the redundant frequency band of the telemechanical of 300 ~ 3400Hz, opens up a sense channel.As Fig. 2, with two groups of 2600Hz Hi-pass filters and 2400Hz low-pass filter, be connected respectively to telemechanical uplink and downlink branch road, the 800Hz oscillator is delivered to the 2400Hz low-pass filter of downstream branch; The 2400Hz low-pass filter of up branch road connects and also connects dual trace oscilloscope, measures the 800Hz signal amplitude and the waveform that receive through loop.The present invention selects 2400Hz low-pass filter and 800Hz oscillator to be because such and original power line carrier has versatility, there is no need to develop the wave filter and the oscillator of other frequencies, and 2400Hz low-pass filter filtering characteristic realizes that easily the sound of 800Hz oscillator is pleasing to the ear, waveform is good-looking.
The detection of general analog channel will be used the detection inserted sheet, the pulse code modulation (PCM) pcm audio Wiring module of main website is provided with the insertion check point, respectively there are two contacts on Dui Ying detection inserted sheet two sides with it, and four corresponding four-core cables in contact are drawn, and every cable is received on one group of wave filter.During detection, the PCM sound that descending detection inserted sheet is inserted into down direction is joined in the module of can breaking, and the plug two sides indicates Z
1, P
1Distinguish direction, the PCM sound that up detection inserted sheet is inserted into up direction is joined in the module of can breaking, and same plug two sides indicates Z
2, P
2Distinguish direction; Inserted sheet is detected at two places can not the wrong plug seat, can not anti-inserted direction, otherwise can't detect.Can not be meant at the wrong plug seat: the seat of uplink and downlink can not wrong plug, in case wrong plug just transmit obstructed; Anti-inserted direction is meant that two faces that detect blade plug can not be anti-inserted, in case anti-inserted just that high pass is opposite with low-pass filter intervention path also can't be finished transmission.Therefore, in the uplink and downlink path, any insertion mistake just can't be tested.And the analog channel detection module carries out data and gathers when detecting being connected to computing machine, because computing machine can be realized automatic detection, also can detect inserted sheet.
The wiring of transformer station's end, need only be with the input and output lead-in wire of 2400Hz low-pass filter, snap into the clamping cutter on the sound distributing frame terminal of PCM respective channels " four lines receipts " and " four lines are sent out ", be regardless of direction, low-pass filter is fixed on position suitable in the communication cabinet.
Next, give 800Hz oscillator and dual trace oscilloscope the logical power supply of going up, the output impedance of 800Hz sine-wave oscillator is provided with 600 Ω shelves, output level is arranged on-5～0dB between, at this moment oscillograph one tunnel is shown as the about 1400mV of 800Hz oscillator output waveform voltage
P-p, what another road showed is the signal that comes by the 2400Hz of transformer station low pass loopback, observes two waveforms and compares.Normal condition is: frequency should be identical, and phase place is not necessarily identical, and amplitude has decay, and waveform should not have distortion, otherwise passage just has problem.What we selected for use is passive filter, and all wave filters add the uplink and downlink passage that whole ring rises, the decay of total about 10dB, and the waveform voltage of receiving is about 120mV
P-p
Detection to the dispatch automated system digital channel, it is exactly the detection of RS-232, its principle is very simple, as long as the receipts and the hair ring of data-interface are got up in transformer station, main website terminates on the com port of PC, sends out packet a collection of with detection software, compares after the reception, draw number percent, just can successfully detect digital telecontrol channel.The detection software of RS-232 is a lot, can download on the net.
In order to reach online detection, must use accessory channel just can finish, method commonly used has three kinds: (1) utilizes the detection method of four-wire circuit as accessory channel, and (2) utilize two-wire circuit to make the detection method of accessory channel, and (3) utilize digital circuit to make the detection method of accessory channel.Encircled in the method at these three kinds, when having only the digital circuit of utilization to detect, just can accomplish online detection as accessory channel.
Digital channel detection module of the present utility model such as Fig. 3, the end auxiliary detection channel C H2 of transformer station " sending out " connects with telecontrol channel CH1 " receipts ", " receipts " of auxiliary detection channel C H2 are connected with " sending out " of telecontrol channel CH1, when the main website end detects down going channel, " sending out " of computing machine is connected " the sending out " of telecontrol channel CH1 and " receipts " of auxiliary detection channel C H2 respectively with " receipts ", when the main website end detected data feedback channel, " sending out " of computing machine was connected " the sending out " of auxiliary detection channel C H2 and " receipts " of telecontrol channel CH1 respectively with " receipts "; The wiring of transformer station is fixed all the time during detection.
The network telecontrol channel generally is made of main website end router, optical transmission device and transformer station's network switch.For being mated with the 2M E1 interface of optical fiber communication, main website router, transformer station's switch be connected, in main website router and transformer station's network switch, must use 2Mbps/10Mbps bridge plate, realize the conversion between 2Mbps E1 interface and the 10Mbps Ethernet interface.
The present detection to network channel is divided into two paragraphs: the one, Ethernet interface is detected, and the 2nd, the E1 mouth is detected.Obviously the detection of network channel is online, and testing process is to not influence of dispatch automated system work.
Because Ethernet interface has the IP address, therefore, can on the automatic main site server, use and detect as network measuring orders such as ping to the detection of Ethernet interface paragraph; For the detection of e1 port, the duty that can on the NM server of transmission equipment, check circuit, thereby the quality of judgement passage with the Show order.
Give an example with real system, the dispatch automated system main website adopts the ON2000 system, and system has management server; Fibre optic transmission equipment adopts ATM Cisco 8500 series, and main website uses ATM Cisco 8540 core switch, and transformer station is ATM Cisco 8510, and main website is equipped with NM server:
(1) on the ON2000 of robotization main website system server, detects Ethernet interface
Fig. 4 is the network channel block diagram that main website arrives each transformer station, marked the IP address of each Ethernet interface among the figure, these port addresss are exactly check point, detection method is: enter C: command prompt, use the Ping order, operate as follows: at first, obtain main website end router side port address with the Ping order, when receiving 4 IP bag, show between main website end telemechanical router and the robotization ON2000 system communicate by letter normal, then again with Ping order acquisition transformer station switch ports themselves address, equally, when receiving 4 IP bags, the passage of expression from the main website server to transformer station's switch is good, that is to say that this network telecontrol channel is normal.Except with the Ping order, can also detect route with the Tracert order.If when Ping switch IP, the IP bag of " Request timed out. " such 4 mistakes appears; When particularly detecting, occur " Request timed out. ", illustrate that this network channel is obstructed with the Tracert order.At this moment need interlude, the E1 passage of transmission equipment is detected.
(2) on optical transmission device ATM NM server, detect the E1 mouth
Open ATM Cisco 8540 server windows, behind input login name and the password, enter server interface.Just can check that the state of these two ports, parameter such as report an error just can judge the quality and the error code degree of this passage with show order.Detection method is divided two parts:
The one, check the e1 port of the end ATM of main website 8540:
Lishui8540#show?ces?interface?cbr?12/0/1
Interface: CBR12/0/1 Port-type:E1-75ohms-DCU

Therefrom find out: port real-time status IF Status and supervisor status Admin Status are logical Up, are not to disconnect Down.Data layout DataFormat is destructuring UnStructured's, is suitable for connecting the network in telecontrol passage; And structuring Structured, be applicable to connect PCM.Do not alarm NoAlarm simultaneously, also do not report an error, promptly all Errors items are 0 entirely.
The 2nd, check the e1 port of the ATM8510 of transformer station, inspection method and ATM8540 are roughly the same.Check the ATM of transformer station 8510 e1 ports show it also is normal as a result, that is to say that this 2M circuit is good.On the contrary, if the 2M circuit has problem, can in every index, show.
In order to guarantee the safety of ON2000 system of dispatch automated system main website and ATM communication facilities network management system, this two cover system all is a private network independently, and there are physical isolation in they and LAN (Local Area Network) and Internet.Therefore can not sign in to these two servers from LAN (Local Area Network) and detect, detection time, place are restricted.And above need of work testing staff is operation in front of server, makes troubles to testing like this.Along with being on the increase of substation site, plant maintenance personnel's continuous minimizing, if can be in any place can logon server, that just can detect the quality of network in telecontrol passage at any time.The utility model improves the network channel detection module, makes it to carry out on-line monitoring easily.
Network channel detection module of the present utility model uses modulator-demodular unit (Modem) access method: the inside line line is set, the com interface that connects main website automation system server and ATM communication facilities network management system server by modulator-demodular unit respectively, as Fig. 5, two other server is connected to computing machine through change-over circuit, as Fig. 1.So just can sign in to this two servers by inside line respectively, carry out network channel and detected.Thus, no matter at that time in which transformer station's work, as long as telephone wire is inserted into the notebook computer RJ-11, just can carries out network channel and detect, detection method is identical with operation on server.When using network channel detection module of the present utility model, even the testing staff not in this locality, can finish the detection to network channel in the same old way.That is to say that the professional goes on business or participates in when training,, can Telnet detect as long as be with notebook computer.
The utility model gathers above three module, and by change-over circuit, the data of three detection modules are converted to and are fit to the form that computing machine receives: the detection of analog channel is a four-wire circuit, and two lines are to send, and other two lines are as acceptance; The detection of digital channel is a three-wire system, i.e. sending and receiving and ground; The crystal head of the detection of network channel for making with grid line, the grid line of making is direct-connected line, and the analog channel detection module is received the RS-232 interface of computing machine after the output of digital channel gathers through the output of 485/RS-232 change-over circuit through the output of mould/number conversion circuit, network channel detection module.
The utility model is selected the programming of Visual Basic visible language for use, and the interface is simply clear, is dialogic operation, easy operating.Gather the detection data with computing machine, except detectable failure, all right sense channel index, whole use is the computer interface push-botton operation entirely, as shown in Figure 6, is operational flow diagram of the present utility model.
At first sign in to system and select the interface, need to select a transformer station of detection; Select type of detection again: if there is channel failure in certain transformer station that has notice, at this moment just select to carry out the telecontrol channel fault detect, the failure judgement attribute, the data that detect back three detection modules gather, and show the fault detect result, i.e. telemechanical apparatus fault or communication equipment fault, if select parameter index to detect, the meeting computing machine demonstrates each property value of telecontrol channel after detecting so, does not need the professional, and any people can finish fault detect in 1 minute.This just can distinguish the guilty culprit position, can shorten the fault handling time of dispatch automated system, improves the reliable rate of dispatching automation.
