Description

Voltage regulating station monitoring system with the dual power supply that timing is restarted

Technical field

This utility model relates to the voltage regulating station monitoring system of a kind of dual power supply restarted with timing.

Background technology

Owing between natural gas pressure regulating station, Regional Distribution is wider, the gas consumption every time adding up each measurement unit by traditional manual metering mode needs to expend the resources such as a large amount of manpower and material resources, workman's inefficiency, the natural gas motorcar situation of each user cannot in time, dynamically be understood by Enterprises Leader and relevant departments simultaneously, hinders the further raising of enterprise management level.

For adapting to the development of gas cause, require that gas enterprise is to data and site environment situations such as gas distribution station, voltage regulating station, priority industry user, the safe operation situation of pipe network key node, operating pressure, flow, temperature, implement dynamically monitoring, Remote management. But there is mains failure, and electricity consumption dispute and DTU unstability, the monitoring leak caused and phenomenon can not be responded.

Utility model content

Technical problem to be solved in the utility model is to provide for a kind of raising monitoring efficiency, the voltage regulating station monitoring system of the dual power supply restarted with timing uninterruptedly monitored for 24 hours.

In order to solve above technical problem, this utility model provides the voltage regulating station monitoring system of a kind of dual power supply restarted with timing, this system is provided with dual power supply, and in original voltage regulating station monitoring system, increase effusion meter, pressure transmitter, pressure difference transmitter, temperature transmitter, valve positioner, combustible gas leakage detection transmitter, uploaded onto the server by data acquisition module, it is achieved that the unmanned monitor in real time of voltage regulating station.

Described dual power supply, one is civil power, and another redundancy is photovoltaic generation, monitors system with powered by direct current to voltage regulating station.

Adopting dual power supply, by 220V civil power as conventional power supply, stand-by power supply is photovoltaic generation, draws money on credit most and holds the 7 day time of use. Solar energy photovoltaic panel converts unidirectional current, each power consumer apparatus in supply voltage regulating station monitoring system to by controller, DC-DC, and is stored in colloid storage battery by unnecessary electricity. When depletion of YANG light, controller automatically extracts electricity from colloid storage battery and normally uses supply each device in voltage regulating station monitoring system, it is to avoid the voltage regulating station caused because of modes such as power failures monitors thrashing.

Wireless data transfer module DTU in voltage regulating station monitoring system adopts timing reset, increases the time relay, makes DTU restart once in every 24 hours, it is to avoid because of the voltage regulating station monitoring error that the situations such as DTU deadlock cause.

Superior effect of the present utility model is in that:

1) adopting dual power supply, accumulator is the longest supports 7 days continuous firings;

2) DTU is provided with and regularly restarts function, solves the DTU problem crashed;

3) monitoring efficiency is improved, uninterruptedly monitoring in 24 hours, reduces line attendant's operating pressure.

Accompanying drawing explanation

The Figure of description constituting the part of the application is used for providing being further appreciated by of the present utility model, and schematic description and description of the present utility model is used for explaining this utility model, is not intended that improper restriction of the present utility model. In the accompanying drawings:

Fig. 1 is theory diagram of the present utility model;

Fig. 2 is dual power supply theory diagram.

Detailed description of the invention

Below in conjunction with accompanying drawing, embodiment of the present utility model is described in detail, but the multitude of different ways that this utility model can be defined by the claims and cover is implemented.

Embodiment of the present utility model is described in detail below in conjunction with accompanying drawing.

As shown in Figure 1, this utility model provides the voltage regulating station monitoring system of a kind of dual power supply restarted with timing, this system is provided with dual power supply, and in original voltage regulating station monitoring system, increasing effusion meter, pressure transmitter, pressure difference transmitter, temperature transmitter, valve positioner, combustible gas leakage detection transmitter, the data such as the pressure in each voltage regulating station, temperature, flow are dynamically sent to the Surveillance center at civil gas management place by data acquisition module. Surveillance center be responsible for received data are analyzed, store, generate form, curve display process, and report to the police when improper combustion gas transmission state occurs, enable field failure in time, effectively process, it is to avoid to produce bigger economic loss.

This utility model, on the basis of tradition voltage regulating station monitoring system, increases floor data real-time acquisition device, including inlet pressure, outlet pressure, stand case temperature, combustable gas concentration, valve state etc.; Combining with GIS, the cartographic information at gas ductwork shows voltage regulating station dotted state; Voltage regulating station point data was reported to the police and Valve controlling beyond normal range; Monitoring data trend figure shows, understanding website traffic-operating period directly perceived.

As in figure 2 it is shown, usually by 220V mains-supplied, when running into the situations such as power-off, photovoltaic generation power. During mains-supplied, 220V civil power meets control chamber 220Vin, control chamber 220Vout and meets ACDC, the ACDC of Flameproof box the 24V voltage of output connects the ACDCVin interface of control chamber, exports to load (monitoring device) eventually through 24Vout; Photovoltaic generation is converted light energy into electric energy by solar energy photovoltaic panel by controller and is stored in non-maintaining colloid storage battery, it is necessary to extract from accumulator during use, and is boosted to each current consuming apparatus during 24V unidirectional current supply voltage regulating station monitors by DC-DC. When depletion of YANG light, controller automatically extracts electricity from colloid storage battery and normally uses for each equipment. This approach avoid the voltage regulating station monitoring thrashing because the modes such as power failure cause.

Timing used is restarted the time relay used and is placed on 24Vout, and whether civil power or photovoltaic generation all can be timed and restart.

The foregoing is only preferred embodiments of the present utility model, be not limited to this utility model, for a person skilled in the art, this utility model can have various modifications and variations. All within spirit of the present utility model and principle, any amendment of making, equivalent replacements, improvement etc., should be included in protection domain of the present utility model interior within.
