A kind of telecontrol channel device for discriminating failure provided in this embodiment is suitable at following several telecontrol channel failures
Reason.
The first situation:
When there is a situation where special line channel interrupts for our station, maintenance personnel is by sending the short message editted to master controller.
Master controller generates voltage change by leased-line interface, and the relay of special line probe senses the variation of voltage, closing relay 1
With relay 2, special line channel is kept from ring.Maintenance personnel carries out this four line loop downward message in scheduling station from after ring
Test, message then can determine whether normal to the circuit between scheduling station herein by being recycled to main website again from ring.If main website
Message is not received, then judges that there is disconnection point failure in circuit between scheduling station herein.
If it find that the circuit herein between scheduling station is normal, then transmitting short message disconnects the relay 1,2 kept
To release from ring, new short message is sent to master controller, and master controller makes the special line at next place pop one's head in from ring, then can determine whether this spy
Whether the circuit between head and a upper probe is normal.And so on, complete the loopback test of all probes.
Second situation:
When there is a situation where special line channels from ring or to get lines crossed for our station.Short message can be transmitted in maintenance personnel, is made by master controller
Special line probe actively disconnects the relay 3,4 of special line probe, to disconnect special line channel, if main website still can see from ring, string
The message of line then illustrates that the circuit between scheduling station exists from ring, failure of getting lines crossed herein, and so on can check other specially
Circuit between line probe.
The third situation:
When network channel breaks down, master controller is by cable access switch, with telecontrol device network channel same
One network segment, maintenance personnel can be by sending short message each network equipment for pre-seting master controller ping test and telecontrol device
Ip, to test each equipment on telecontrol device network channel whether normal operation.
4th kind of situation:
When all probes all show that special line channel is normal, network channel also be can be used, and can determine whether as telecontrol device failure.Safeguard people
Member can restart module by telecontrol device and restart telecontrol device.Relay 1 is disconnected, makes telecontrol device power down, then closes relay 1,
Telecontrol device will power on and start automatically.
It should be noted that the network interface of master controller can be used as maintenance port use, if maintenance personnel in substation,
Then can by using laptop connect master controller come realize pop one's head in everywhere from ring and network test, process is same as above, no
It is described in detail again.
The utility model is by a master controller and multiple special lines are popped one's head in, telecontrol device restarts module, several relays are opened
Composition is closed, is applicable to cover the substation of telecontrol device more.
The utility model can allow maintenance personnel to send order for special line channel from ring or disconnection by mobile phone, be accurately positioned
The position of special line channel failure point, and telecontrol device network channel fault point can be judged by network connection, to decide whether to pacify
Row's communication or relay protection personnel go to substation, and carry the spare part of which kind of equipment.To be unfamiliar with telemechanical special line channel and network channel
Staff accurate instruction is provided, offer convenience to eliminate defect.Finally, the utility model can pass through power-off weight
Telecontrol device is opened to solve the seemingly-dead defect of part telecontrol device.
The above, above embodiments are only to illustrate the technical solution of the utility model, rather than its limitations；Although ginseng
The utility model is described in detail according to previous embodiment, those skilled in the art should understand that: it is still
It is possible to modify the technical solutions described in the foregoing embodiments, or part of technical characteristic is equally replaced
It changes；And these are modified or replaceed, various embodiments of the utility model technical solution that it does not separate the essence of the corresponding technical solution
Spirit and scope.
