Description

A kind of ash library wireless transmission solar energy instrument control device
Technical field
The utility model belongs to coal-fired power plant field, and in particular to a kind of ash library wireless transmission solar energy instrument control Device.
Background technique
Currently, generally there are 2~3 grey libraries in the coal-fired power plant of two generating set, grey library is typically located at power generation The position of separate main building in factory, 30 meters or so of grey library height, more than ten meters of diameter.The needs for being run and being monitored according to system, often 1 continuous material level meter, 2 level switch, the pneumatic switching valve of several ash handing pipelines are set on a ash library.
Operational version in generation current factory are as follows: 1 grey library thermal control power supply disks of setting, are above-mentioned instrument and pneumatic switching Valve power supply;The monitoring of above-mentioned instrument and valve, control signal are hardwired to DCS remote I/O cabinet, it is logical by DCS remote I/O cabinet It interrogates to DCS and monitors.Under such scheme, grey library thermal control power supply disks and DCS remote I/O cabinet are placed in the gasification wind near grey library Computer room realizes the power supply and control of grey library instrument and pneumatic switching valve by plant area's conduit line cabling.But such side The shortcomings that case is as follows: cable length long (100 meters or so), mounting cost are high;Exclusively for one thermal control power supply disks of grey lab setting at This is higher.
Utility model content
For above-mentioned the technical problems existing in the prior art, the purpose of the utility model is to provide a kind of grey libraries with wirelessly Transmit solar energy instrument control device.
The purpose of this utility model is achieved through the following technical solutions.
A kind of ash library wireless transmission solar energy instrument control device, by controlling based on the continuous material level of power plant ash library, expecting Bit switch and pneumatic switching valve, the control device include solar power generation unit, power distribution unit, data acquisition unit and small-sized Control unit;
Solar power generation unit is connect with power distribution unit, and power distribution unit is respectively continuous material level meter, level switch, pneumatically cuts Change valve, data acquisition unit and the power supply of small-sized control unit;
Data acquisition unit is connect with continuous material level meter, level switch, pneumatic switching valve and small-sized control unit respectively;
Wireless module is connect with small-sized control unit.
The solar power generation unit includes solar energy photovoltaic panel, controller, battery and inverter, solar energy photovoltaic panel It is connect with controller, controller is connect with battery, and battery is connect with inverter, and inverter is connect with power distribution unit.
The utility model has the following beneficial effects: solar energy instrument control device provided by the utility model utilizes power plant ash The different position of Al Kut and the advantage using solar energy, using solar powered and wireless transmission method, instead of tradition The mode of thermal control power supply disks and cabling transmission signal is separately provided in grey library instrument and pneumatic switching valve, greatlys save artificial Expense and equipment cost can bring good economic benefit.
Detailed description of the invention
Fig. 1 is the principles of the present invention schematic diagram.
Specific embodiment
As shown in Figure 1, a kind of ash library wireless transmission solar energy instrument control device, continuous for controlling power plant ash library Level-sensing device, level switch and pneumatic switching valve, control device include solar power generation unit, power distribution unit, data acquisition unit, Small-sized control unit and wireless module.
Solar power generation unit is connect with power distribution unit, and power distribution unit is respectively continuous material level meter, level switch, pneumatically cuts Change valve, data acquisition unit connects power supply with small-sized control unit, it is gentle that solar power generation unit can be realized grey library level-sensing device Move the solar powered on the spot of switching valve.
Data acquisition unit is connect with continuous material level meter, level switch, pneumatic switching valve and small-sized control unit respectively, Data acquisition unit by acquiring based on continuous material level, the status signal of level switch and pneumatic switching valve, data acquisition unit will Collected status signal transmission is to small-sized control unit.Continuous material level meter, level switch, pneumatic switching valve itself all have inspection The function that survey state concurrently does well, data acquisition unit are the prior art, and the utility model is not described in detail.
Small-sized control unit is connect with data acquisition unit, and small-sized control unit receives the scene of data acquisition unit acquisition Signal simultaneously sends control signal, realizes the chain control of grey library material position and pneumatic switching valve.
Small-sized control unit is connect with wireless module, and wireless module is for the ash disposal system by data wireless communication afield System.
Solar power generation unit includes solar energy photovoltaic panel, controller, battery and inverter, solar energy photovoltaic panel and control Device connection processed, controller are connect with battery, and battery is connect with inverter, and inverter is connect with power distribution unit.
The working method of the utility model are as follows: wireless transmission solar energy instrument control device is arranged in grey Ku Kuding;Too Positive energy generator unit receives solar power generation, and solar power generation unit connects power distribution unit, the electricity of sending is sent to power distribution unit, Each grey library continuous material level meter of power distribution unit connection, level switch and pneumatic switching valve, provide power supply for them.
Each grey library continuous material level meter of data acquisition unit connection, level switch and pneumatic switching valve, acquire their signal And transmit associated control signal.Meanwhile data collection system gives data internal communication to small-sized control unit, in small-sized control list The chain control of grey library continuous material level meter, level switch and pneumatic switching valve is realized in first.
When continuous material level meter detects that grey library material position is high, small-sized control unit compared with the threshold value of storage inside, if The ash handing pipeline that the ash library is then alarmed and cut off by closing pneumatic switching valve more than threshold value, opens level switch, starts to unload ash;When When continuous material level meter detects grey library material level ultrahigh, ash-transmission system is cut off.Above-mentioned small-sized control unit carries out the mistake of threshold value comparison Journey is the routine techniques of those skilled in the art.
Small-sized control unit by wireless module by data wireless communication afield remove ash handing system, data are shown In control room, displayed data in control room and off-limit alarm.
Other technologies are referring to the prior art.
The above is only preferred embodiments of the present invention, is not the limit to technical solutions of the utility model It is fixed, it is noted that those skilled in the art can also make further under the premise of technical solutions of the utility model Improvement and change, these improvement and change should all be covered within the protection scope of the present utility model.
