Accompanying drawing explanation
Fig. 1 is the structure chart of the energy-conservation settlement system preferred embodiment of air compressor in this utility model.
Detailed description of the invention
This utility model provides the energy-conservation settlement system of a kind of air compressor, for making the purpose of this utility model, technical scheme and effect clearer, clear and definite, further describes this utility model below.Should be appreciated that specific embodiment described herein, only in order to explain this utility model, is not used to limit this utility model.
nullAs shown in Figure 1，The energy-conservation settlement system of the air compressor that this utility model provides，For air compressor 10 is carried out energy-conservation clearing，Wherein，Including one for recording the ammeter 100 of the energy consumption data of described air compressor 10、For recording flow transducer 200 and the PLC 300 of the air usage amount data of described air compressor 10，One end of described ammeter 100 and flow transducer 200 all electrically connects with air compressor 10，The other end of described ammeter 100 and flow transducer 200 all electrically connects with described PLC 300，Described PLC 300 is provided with S7-200 chip，Classify for the energy consumption data that described ammeter 100 and described flow transducer 200 are recorded respectively and air usage amount data、Statistical disposition，Thus draw energy-conservation checkout result.
Further, described PLC is again programmable logic controller (PLC) (Programmable Logic
Controller, is called for short PLC), it is a kind of digital electronic device with microprocessor, for the digital logic controller of Automated condtrol, store in control instruction can be loaded internal memory at any time and perform.Programmable Logic Controller is by innernal CPU, and the unit institute modularity such as instruction and data internal memory, input-output unit, power supply module, digital simulation is combined into.
Compared to prior art, the energy-conservation settlement system of the air compressor that this utility model provides, the continuous data of the most scattered metering outfit (such as ammeter 100, flow transducer 200) is integrated together before making, and by PLC 300, air compressor 10 carries out energy consumption analysis and energy-conservation accounting.
Air compressor is that the power consumption greatly of four in motor system one of sets, how to calculate and the energy consumption of metering air compressor 10, never have the unified or mode of industry accreditation and method, the power consumption data with ammeter metering having carries out lateral comparison, this mode, it is impossible to allow industry accept with energy enterprise, because air compressor has loading, unloading, unloaded several duties, wherein, unloading and unloaded two states do not produce compressed air, i.e. flog a dead horse；Meanwhile, along with equipment has use state different, under equal-wattage, gas production also has difference.Sum it up, the duty of air compressor 10 is different, power consumption is the most different from gas production, thus horizontal ammeter data compare cannot be as determining whether energy-conservation foundation.If only using gas production as single comparison parameter, its status of energy consumption cannot be confirmed especially.To this end, only both data are combined together, the power consumption needed for often producing 1 cube of compressed air as observable index compared with according to being rational, also accepted by available energy enterprise of institute.
Operation principle of the present utility model is as follows: based on 485 agreements, with specific time point for initial time axle, the power consumption data read in an ammeter 100 for every 5 minutes and the data on flows in flow transducer 200, carry out the addition of homogeneous data, obtain the total electricity consumption in the time period and data on flows, in also calculating this time period, often produce the power consumption needed for 1 cube of compressed air i.e. m3The energy saving profit that/min/KW, energy saving profit and both sides share.Meanwhile, form clearing earnings report, can directly export printing, as the energy-conservation proof of system.
Can quickly be drawn the energy-conservation checkout result of air compressor by this utility model, it is easy and simple to handle, saving manpower, can be effectively improved work efficiency.
Further, in this utility model, the described ammeter other end and the flow transducer other end are all electrically connected with described PLC by RS485 interface, described RS485 interface is the combination of balance driver and differential receiver, its anti-common mode disturbances ability is strong, i.e. noise immunity is good, and the data maximum transmission rate of RS-485 can reach 10Mbps.
Because RS-485 interface has a good noise immunity, the above-mentioned advantage such as long transmission range and multistation ability just becomes the serial line interface that this utility model is first-selected.Can quickly and be accurately transferred in PLC 300 by RS485 interface, the power consumption data of described ammeter 100 record and the air usage amount data of flow transducer 200 record.
Further, owing to the complexity of engineering site is with uncertain, there are not simple mapping relations between each data, i.e. one ammeter 100 corresponding can connect multiple stage air compressor or the situation such as multiple stage air compressor connection one or the multiple flow transducers 200 of corresponding connection, concrete, such as, described flow transducer 200 can be simultaneously connected with 3 air compressors 10, described ammeter 200 can connect an air compressor 10, it is possible to connects 2 air compressors 10.For simplifying the complexity that data process, it is a project that this utility model is compiled with machine room for unit, is overlapped with data on flows by an all ammeter of project, then calculates the amount of energy saving of whole project.
Further, in this utility model, described energy-conservation settlement system also includes the display screen 400 electrically connected with described PLC 300, and described display screen is used for showing energy-conservation checkout result.
Further, described energy-conservation settlement system also includes one for printing the printer of energy-conservation checkout result.
Further, described energy-conservation settlement system also includes one for the lightning-protection module preventing described energy-conservation settlement system to be struck by lightning.
In sum, energy consumption data that described ammeter and described flow transducer are recorded by PLC by this utility model respectively and air usage amount data are classified, statistical disposition, thus draw energy-conservation checkout result.Can quickly be drawn the energy-conservation checkout result of air compressor by this utility model, it is easy and simple to handle, saving manpower, can be effectively improved work efficiency.
Should be understood that; application of the present utility model is not limited to above-mentioned citing; for those of ordinary skills, can be improved according to the above description or convert, all these modifications and variations all should belong to the protection domain of this utility model claims.
