Description
Technical field
The present invention relates to computer realm, particularly relate to a kind of fire emergency lamp comprehensive detection system and method.
Background technology
Fire emergency lamps total quality allows of no optimist, and is mainly manifested in: the emergency time does not reach the 90min of standard-required; Sheathing material adopts combustible material mostly; Final voltage is on the low side; Fail to meet 80% of master gauge rated voltage requirement; Discharge and recharge long duration test last does not reach 85% of discharge time first and answers >=90min discharge time; Figure and word do not meet standard-required etc.Cause fire emergency lamps product quality inferior, the reason not meeting national standard mainly contains the following aspects:
1, thin, the management system of enterprise-quality consciousness falls behind, lacks qualified technical personnel
China's fire emergency lamps national Specification, the every batch products of fire emergency lamps manufacturing enterprise must carry out factory inspection by product standard requirement before dispatching from the factory, and clear stipulaties factory inspection project, every batch products provides by production unit the qualified book that dispatches from the factory after the assay was approved through product quality, can put goods on the market.But the detection of a little outward appearance and so on that had considerable part manufacturer just to do, not tight to check on to stock up pass, important step such as processing pass, assemble flow pass, factory testing pass etc. of starting material in production run, even become a mere formality, the inspection just in order to deal with fire supervision department; Some manufacturer lacks necessary checkout equipment, individual other does not have checkout equipment even at all, especially those production scales are little, just set foot in the enterprise of fire product, mostly be that " family workshop " formula is produced, enterprise-quality consciousness is thin, and production technology, managerial experience lack, and just can not produce qualified product really up to the mark at all; Economic benefit is pursued simply by some manufacturers, reduce cost of products by every possible means, key components, parts are onlyed demand to low price and do not asked quality, What is more, for reaching low cost object, the product technology standard-required of intentional reduction associate components, causes bum fire emergency lamps to come into the market.On the other hand, enterprise personnel quality is general not high, and from checking that situation was not difficult to find to fire emergency lamps producer in recent years, the workman that most enterprises is recruited was cheap labour, and cultural quality is low, and just not on duty hurriedly through professional technique training; Even the quality of Some Enterprises or person in charge of the technology aspect self also have little understanding to related products index.In addition, enterprise's " family " phenomenon is comparatively general, and causing business administration system unreasonable, many business entitys, is chief executive, is again workshop class, group leader.The enterprise talent proportion structure numerous imbalances, particularly the middle management talent, technician are out of stock, and talent competition mechanism cannot be formed, and tachnical storage is difficult to catch up with social development paces with rapid changepl. never-ending changes and improvements and market development demand.
2, enterprises propagandist implements that standard is ineffective, operative norm is tight, technological innovation initiative is not high
The existing fire emergency lamps standard GB17945-2000 " fire emergency lamps " of China was issued on January 30th, 2000, and enforce on October 1st, 2000, and fire emergency lamps product continues to use always before this is Ministry of Public Security industry standard GA54-93 " fire-fighting emergency headlamp tool general technical specifications ".Old and new standard contrasts, a lot of performance index of product have done corresponding increase and redjustment and modification, industry standard more in the past, existing national standards has required very large improving to fire emergency lamps technical conditions, for guaranteeing that fire emergency lamps quality provides better, stronger legal guarantee.But even to this day, new standard situation is performed from the producer producing fire emergency lamps, have part producer only new standard a surname to be passed through several major technique personnel, and other employees also do not know what new standard is, do not perform new standard in each link of producing and operation simultaneously yet; Some enterprise product design documents and pattern still continue to use former standard so far, do not carry out product approval by new standard, and the transformation of fire emergency lamps product technology is not known where to begin especially with innovation; Considerable part enterprise for pursuing economic benefit and immediate interest, still at sale stock, very disruptive fire emergency lamps market order.To this, enterprise to new standard a surname pass through ineffective, perform tight, technological innovation consciousness is weak, indifferent, policy and the mechanism of technological innovation are not in place, not only have impact on product quality, and it is slow to cause current product update paces, is not suitable with the situation of the market demand.
3, disorderly competition between enterprise, user pursue at a low price simply
Fire emergency lamps production and sales industry is the same with other industry, and same market competition is very fierce, and product price war becomes a flash point increasingly.Manufacturer is in order to occupy market, generally expanded sales by sale of demanding a lower price, make a price reduction the only resource seemed into enterprise participation market competition of fighting for sale, ignore the primary factor of expanding market for commodities---product quality, result manufacturing enterprise makes an issue of by fair means or foul on starting material, components and parts, some manufacturing enterprise simplifies production process and trace routine even artificially, and to reach the object reduced costs, thus it is not high to result in current fire emergency lamps total quality level.On the other hand, user self security against fire consciousness is not also cause product quality not high factor that can not be ignored by force.Some user is unilateral to be thought, fire control equipment drops into can not produce direct economic benefit, can economize and then economize.Put undue emphasis on the low price of product therefrom, ignore product quality requirement, individual user even knows that vacation is bought in vacation, and only figure is cheap, sells provide market to underproof fire emergency lamps.
Current domestic fire emergency lamps detection method has a lot, and checkout equipment is also uneven, in general, present stage fire emergency lamps checkout equipment exist deficiency mainly concentrate on the following aspects.
1, functions of the equipments are single
Every platform checkout equipment can only detect single project, and carrying out the detection of fire emergency lamp all events needs to purchase multiple devices, and fund input is large, inefficiency;
2, automation degree of equipment is low
Test findings mostly is visual inspection, as: the switching time of fire emergency lamps measures, by artificially proceeding to emergency rating from main electricity, then switching time is determined with stopwatch, because human eye has certain delay when light fixture changes, so the value of actual test is greater than working value own, the result obtained so is also inaccurate, and everyone is different, the test result obtained also has difference, if test result is in critical conditions, just easily cause the erroneous judgement of result, by manually filling in experimental test record document, there is larger error in assay,
3, design of testing device is simple
Human-computer interaction is poor, and operation is inconvenience very, if testing staff thinks that the detection of grasp one series products needs to learn the method for operating of multiple devices, brings very big inconvenience to work.By investigating the quality supervision and test department at current domestic every country quality testing center and each province, all develop some simple fire emergency lamps checkout equipments targetedly according to the actual conditions of oneself, intelligence degree is not high, function singleness, the sample size of one-time detection is few, and efficiency is low.
