Description
Technical field
The technology scope touched the invention belongs to protect article to stop.It refers in particular to towards museum exhibits, synthesis is active/passive infrared
Technology, using light, sound, mechanical obstruction means, the obstruction with intrinsic safety feature touches device and method.
Background technique
With advances in technology, museum grows with each passing hour to public propagation and the mode of displaying: the digital virtual of propagation is complete
Scape browser technology, displaying the automatic guide to visitors technology of two-way interactive.Comprehensive three-dimensional reconstruction, digitized video synthesis, multimedia interactive are compiled
Museum's circulation way of journey technology, marked achievement are to be presented in online virtual (number) museum: 2000, online
The Forbidden City website, panorama type shows the Forbidden City style and features；On April 29th, 2016, the Chinese Academy of Sciences release jointly together with more academic institutions
Digital Dunhuang system.Currently, the mainstream exhibition method in domestic museum also rests on the static unidirectional stage, by label text
Word, picture information combination guide describe story, and spectators is helped to understand showpiece.Static unidirectional exhibition method is by denouncing: showpiece
Limited space, label are real difficult full and accurate；Static text content shows single dull；Although guide provides certain interaction, number of having no alternative
An utterly inadequate amount is measured, and the quality and quantity interacted varies with each individual, the high-quality guide under lower treatment is rare.Based on number
And wireless communication technique, display form is experienced in two-way interaction focusing on people, very popular.Morning has been abandoned in two-way interaction experience
The specialized hardware terminal of phase turns to smart phone；Source is related to the liter in equipment leasing, hygienic issues and later period by specialized hardware terminal
Grade maintenance support, and smart phone is resourceful, supports two-way interaction experience.The core of automatic guide to visitors is indoor positioning technologies.
The competitor to go up on the stage has: WLAN, RFID, ZigBee, bluetooth etc., winner of a contest is non-, and WLAN does not belong to；First in addition to WLAN, remaining technology
Additional sender unit is all needed, two carry out smart phone standard configuration WiFi.
Museum practice have shown that, virtual network (number) museum is useful supplement and the extension in entity museum, entity
Museum itself has irreplaceable speciality and glamour；It is the accessory exhibition side in kind displayed that the three-dimensional of showpiece, which is shown,
The experience sense that formula, the dignified sense of the intrinsic history of showpiece in kind and spectators go through the veil of time is by three dimensional virtual technique can reach absolutely not.
Craving of the spectators to showpiece in kind, and Zero-Distance Experiencing requirement in kind is watched, sternness is proposed to museum management person
Challenge.Showpiece is watched across showcase glass, the experience of spectators is not good enough；Shop side, which withdraws, to display exhibits, and meets zero distance optimum experience
While, showpiece is but repeatly by touch damage.Reinforce social morality publicity, advocate love showpiece, is the one side of problem, but far from
It is enough；Exploitation, which stops, touches device, technological means of seeking help protects showpiece, reenacts necessary disciplinary measures, and shop side, which withdraws, to be displayed out
Showpiece just has safety guarantee.So far, it stops and touches device and still locate blank and urgently fill up, now discuss design and stop and touch device and should abide by
The basic norm kept.
Firstly, low expense.Financial allocation is leaned in museum, and high cost is unbearable, therefore it is preferred that cheap infrared technique.
It is carried out since more than 9 one-tenth touches faces showpiece, showpiece front is preferred to detect protection, side with highly sensitive active infrared
Face is quasi- to seek the less expensive passive infrared detection protection of price.
Secondly, few O&M.Museum's O&M manpower is deficient, bases oneself upon outsourcing；Therefore the structure for stopping touch device is preferably simple and reliable,
It can even take the circumstances into consideration to reduce automation, " top news " is to ensure the reliable and few maintenance for touching device.
Third, high safety.It stops touch device directly to contact with spectators, power supply safety is necessary, therefore designs 24V intrinsic safety
Power supply.In addition, blocking rod material uses high expansion and contraction rubber, thrust≤40N of blocking rod；Therefore, it stops and touches device machinery side
Method stops violator, and will not injure violator.
4th, it is integrated.Museum's standard configuration video monitoring system stops and touches device involvement monitoring system, calling system money
Source take pictures evidence obtaining, fright touch showpiece violator, help promoted stop touch device efficiency and museum whole management level.
Finally, humanized.When stopping touch device implementation obstruction, sequentially integrated application light, sound, mechanical three kinds of obstructions touch hand
Section.Photoresist, which blocks to remind, the violator for touching clue, if violator receives dissuasion, interrupts offending process, photoresist blocks prompting and also stops；
Acoustic resistance blocks the violator that warning has touch behavior, if violator, which can listen, advises receipts hand, acoustic resistance is blocked warning and also stopped；Machinery stops to be hindered by force
It is disconnected to touch, adjust video monitoring to take pictures evidence obtaining, calling security personnel show up punish it is refusing to mend one's ways despite repeated admonition, lack social morality person.
Propagate as follows with more representational intellectual property Summary on research results on exhibition method in museum:
