Description
Technical field
The utility model relates to a kind of link-down alarm device based on power network dispatching system.
Background technology
In the prior art, known technology is the continuous expansion along with electrical network scale, and the continuous increase of the telecontrol information amounts such as transformer station's remote measure and communication, the requirement effectively reliably uploading scheduling station to telecontrol information is more and more higher.Network channel based on dispatch data net, can realize one-to-many transmission, real-time, reliability is high, plays important leverage effect to electric power dispatching system safe and stable operation.But the link in existing network channel uses ip address mostly, once link is obstructed, just cannot transmit telecontrol information, potential threat is formed to the safety and stability of electric power dispatching system.This is the weak point existing for prior art.
Summary of the invention
The purpose of this utility model, be exactly for the deficiency existing for prior art, and a kind of technical scheme of the link-down alarm device based on power network dispatching system is provided, the device of the program, when link is different, can send warning timely, prompting staff repairs, and ensure that the normal operation of power network dispatching system.
This programme is achieved by the following technical measures: a kind of link-down alarm device based on power network dispatching system, comprise housing, the feature of this programme is: described housing is provided with display screen and keyboard, circuit board is provided with in housing, described circuit board is provided with controller, alarm, communication module, alarm control circuit, described communication module is connected with controller, described controller is connected with alarm by alarm control circuit, and described controller is connected with display screen and keyboard respectively.
Described alarm control circuit comprises a chip IC, 1 pin of described chip IC is connected with+VCC by first resistance R1,2 pin of chip IC are connected with described controller, 4 pin of chip IC are connected with+VCC, 3 pin of chip IC are connected with the base stage of a triode VT by second resistor R2, the grounded emitter of triode VT, the 3rd resistance R3 is connected in series between the base stage of triode VT and emitter, the collector electrode of triode is connected with+VCC1 by relay J, and normally opened contact J-1 and the alarm of relay J are connected and be connected with power supply afterwards.
Described communication module is wifi wireless communication module or zigbee wireless communication module.
Described chip IC is photoelectrical coupler.
Through hole is provided with at the top of housing and both sides.
Protection network is provided with inside described through hole.
Housing is also provided with alarm lamp, and described alarm lamp is in parallel with alarm.
The beneficial effect of this programme can be learnt according to describing of such scheme, can shield owing to there being housing in this scenario to whole device; There is through hole, can dispel the heat; Protection network is provided with in through hole, can blocks dust, play certain protective action; Display screen for carrying out the reality of relevant information, such as any road link fails; Keyboard can operate, and is convenient to user and checks; There is the communication that wifi wireless communication module or zigbee wireless communication module can realize between this device and scheduling station, and be wireless mode, make this device easy to use; After controller receives the warning message that scheduling station sends, control alarm by alarm control circuit and send warning, use photoelectrical coupler, avoiding outer signals affects controller.As can be seen here, the utility model compared with prior art, has substantive distinguishing features and progress, and its beneficial effect implemented also is apparent.
