Description

The instant wireless alarmer of transformer station, electric substation

Technical field

The utility model belongs to electrical control gear, particularly the instant wireless alarmer of a kind of transformer station, electric substation.

Background technology

At present the transformer station of China is, the Intelligent communication module of electric substation is all generally to adopt wired communication modes transmission data, RS232 for example, RS485 and the mode such as to net greatly.Its advantage is that transmission speed is fast, signal stabilization.But when setting up, must set up cable, optical cable etc., excavate cable duct, constructional difficulties, cost are high, need to spend a large amount of human and material resources and time; If line failure investigation is very difficult, the time is long, can not recover in time communication.

Summary of the invention

The object of the invention is to overcome above-mentioned technical deficiency, provide a kind of based on wireless GPRS service, realize the data transmission of wireless public network, between mobile subscriber and data network, provide connection, the transformer station of high-speed radio IP and X.25 integrated data access service, the instant wireless alarmer of electric substation are provided to mobile subscriber or fixed-line subscriber.

The technical scheme that the utility model technical solution problem adopts is: the instant wireless alarmer of a kind of transformer station, electric substation, comprise power circuit, alternating circuit, A/D D/A converting circuit, open into circuit, digital output circuit, host computer, liquid crystal display circuit and keyboard input circuit, it is characterized in that being provided with central logic control circuit in system, central logic control circuit by CPU, scrutable program storage RAM, memory RAM, counter timer, bus controller, I/O is able to programme and serial port able to programme interconnects and forms; Central logic control circuit and A/D D/A converting circuit, A/D D/A converting circuit, the power circuit of opening into circuit, host computer, keyboard input circuit, liquid crystal display circuit, digital output circuit and DC220V/24V/5V are connected.

The invention has the beneficial effects as follows: this utility model, when transformer station, all faults of power transformation occur, can send to the mobile phone of appointment or the PC of online by wireless mode fault alarm information; Overcome the limitation that cable network depends on track laying; Cost is low, uses manpower and material resources sparingly, and malfunction elimination is fast, can recover in time communication.
