Technical field
The utility model relates to a kind of feed-back type ageing system with monitoring function.
Background technology
Ageing system is mainly used in the aging of high-power aluminium base power module, and traditional ageing system exists load to connect the problem that unreliable, load heat radiation difficulty, energy dissipation, operating personnel are patrolled and examined aspects such as wasting time and energy.Why have the problems referred to above, be because: 1, the aging mode of tradition uses cement load aging, owing to use crocodile clip that module is linked to each other with load, when load current is very big, occurs the phenomenon of virtual connections easily; 2, owing to the very big space constraint that is subjected to again of power, the heat radiation of cement load is difficult to guarantee, the phenomenon that load burns out often occurs; 3, use the aging electric energy of cement load all to be converted into heat and distribute, aging for high power module, waste of energy is serious; Need be when 4, operating personnel patrol and examine in measurement module input and output under the hot environment, people's subjective factor influences efficient and measuring accuracy.
The utility model content
The utility model technical issues that need to address just are to overcome the defective of prior art, and a kind of feed-back type ageing system with monitoring function is provided, and it has intellectuality, standardization, energy-conservationization characteristics.
For addressing the above problem, the utility model adopts following technical scheme:
The feed-back type ageing system that the utlity model has monitoring function is made up of three parts: aging chamber, power supply rack, supervisory control comuter.Aging chamber is the module aging equipment, and the power supply rack provides system required power supply, and supervisory control comuter control ageing process is conventional electrical connection between the three.
Aging chamber described in the utility model is made up of ageing rack, loading disk, card extender, power power-supply wave filter, each aging chamber is made up of two ageing racks, each ageing rack is divided into four layers, place 3 loading disks for every layer, each loading disk 8 modules that can wear out at most, calculate by this, the aging ability of every aging chamber is 2 * 4 * 3 * 8=192 piece.Each loading disk is made up of from single-chip microcomputer and 4 tunnel feedback electronic loads a host scm and 4.Host scm is responsible for carrying out communication with supervisory control comuter and four from single-chip microcomputer, controls 4 tunnel feedback electronic loads respectively from single-chip microcomputer for four, comprises load current being set and gathering parameter such as electric current and voltage; The every road of 4 tunnel feedback electronic loads can provide 5A load current to 20A, the load current precision is ± 1%, the module output voltage range that can allow is 18 volts to 40 volts, can independently wear out 600 watts module of each feedback electronic load, also can two or four in parallel uses, use the feedback electronic load to wear out and 70% energy can be returned inlet highway, save the energy.4 acquisition precisions from single-chip microcomputer are as follows: input voltage: ± 500mV, and output voltage: ± 200mV, load current: ± 1%, environment temperature: ± 2 ℃.The effect of card extender is that the module with different pin definitions is connected on the loading disk.The input and output terminal of modular power source generally adopts pin to go out the form of pin, and pin is to adopt 1mm or the straight bar form of other size to draw from modular power source inside; Power is from 0.5 watt supreme kilowatt.It is all different with functional definition that the modular power source overall dimensions and the pin of different capacity goes out the size-spacing of pin, the input and output pin layout and the relative position of disparate modules are different, link to each other with feedback module dish so need by the PCB circuit input and output be defined as unanimity with card extender again.The power power-supply wave filter is with the filtering of bus input voltage.
Power supply rack described in the utility model is made up of 48 volts of control power supplys, battery pack, 60 volts of bus power power-supplies.48 volts of control power supplys: for console panel provides power supply; Battery pack: when unexpected power failure, guarantee that 48 volts of control power supplys can continued power 30 minutes; 60 volts of bus power power-supplies: for 48 volts of input power modules provide power supply.
The function of the utility model supervisory control comuter comprise begin to wear out, finish to wear out, ageing parameter setting, data acquisition, data presentation, audible alarm, literal report to the police.Concrete control procedure is as follows:
1, beginning, end are worn out: by aging the carrying out of computer operation interface control aging chamber modular power source
2, ageing parameter setting: the scope of load current by the aging module of computer operation layout setting and input voltage, output voltage, temperature
3, data acquisition, demonstration: with the data acquisition unit communication in the aging chamber, aging data of acquisition module and subitem show
4, sound, literal are reported to the police: when unusual generation, and the alert notice operator that sounds, and by literal display abnormality phenomenon
5, aging chamber constitutional diagram: show the aging chamber operating position
The RS-485 agreement is adopted in the communication of the utility model computing machine and data acquisition unit
