Part blank screen command function, brightness reaches the human eye comfortable brightness range 200-300nit of viewing before shielding, and there is voltage dynamic to compensate,
Ensure light source of projector brightness slow-decay in 20000 hours life spans.Subway Special projector and the moisture-proof cabinet of protection
Composition projection protective device.Protective device has the functions such as dust-proof, moisture-proof, heat dissipation, and the inlet and outlet of radiator fan can be outside
The dust-proof cotton of portion's quick-replaceable, while meeting vibration and wind pressure requirement in underground railway track region.Require in addition that the machine of Special projector
Body depth is less than 380mm, it is ensured that depth is less than 450mm after protective device installation, meets subway facilities clearance requirement.Cabinet is opened
Door direction is the door-opening mode of up-down structure, and in the case where not locking a door, door body will receive the influence Natural closure of gravity.
Technical solution of the present invention also discloses the detailed content of automatic dispatching, specifically: local system is in industrial personal computer
Monitoring service by custom starting task, polling tasks, timed task, conditioning tasks realize the unattended fortune of system automation
Dimension.By giving each power terminal equipment before the timed task realization metro operation time started, and system trend is initialized, or
The each terminal device of system is closed after metro operation and is disconnected powers；To prevent industrial personal computer long-term operation from causing system not
It is good, industrial personal computer schedule reboot is configured, when restarting, automatic starting acquisition service and monitoring service are appointed by configured starting
Business, the reset system situation after system starting is stablized, is at good state；And configuration condition task, it may be implemented according to disengaging
Signal of standing drives each set projection to open or close on demand.
The Service controls such as remote terminal manually controls, task scheduling drives can all generate an Action number, carry out business
Logic manipulation tracks and is written log, to instruction downlink and uplink whole process analysis, carries out short message to business operation unusual condition
Or mail alarm, maintenance personnel check that more detailed system O&M log carries out abnormal investigation according to alarm notification in time.For
The longitudinal data section of each data pair is recorded and analyzed and is directed under the projection of every set all data to carrying out lateral data
Whether profile analysis carries out abnormal log output by presupposition analysis strategy and parameter, and carried out according to alarm filter policy selection
Short message or mail notification；The advertisement situation for monitoring each playback terminal in real time, to ad distribution success, advertisement expire, advertisement from
Line etc. carries out tracking and short message or mail notification.Local system monitors the communication link state and data traffic in domain, by default
Warning strategies and threshold values analyzed and alerted；All warning information are marked with different brackets, and can be according to region, city
Attach corresponding person liable for city, equipment, and person liable can order on demand the warning information of certain grades and to obtain short message or mail logical
Know.
Generation system O&M reports (monthly, annual), exception reporting, business report, generates advertisement broadcasting, advertisement operation system
Meter report, correlation report periodically send corresponding person liable by mail.

Fig. 9 show the ad distribution timing diagram of embodiment of the present invention.The real-time prison of local service and distal end cloud service
It controls communication data and protecting information safety is realized using dynamic check.Dynamic key initial Shi Youyun center service distribution, when deployment
Initial bind is carried out, the later period is periodically generated new key by center service, is then pushed to local service, the note when running succeeded
Record is put on record, and local update simultaneously caches dynamic key.To be abnormal in reply key updating process, after new key updating, old is close
Key is used there are also one section of entry-into-force time as spare key.
Specifically, in public place, video ads illegal broadcasting in order to prevent needs to carry out more iron dust as illustrated in fig. 9
Procedure control.
1) advertising user must obtain advertising function and advertisement position (i.e. multimedia shield door) hair to administrative staff
The authorization of cloth is likely to carry out ad review application
2) auditor is served as by more people, only responsible content auditing, and advertisement is by that can carry out the advertisement when all audits
Encrypted signature, playback terminal will do it cryptographic check
3) when by the advertisement application publication of audit advertisement, a unique identification can be generated and bound with advertisement position, table
The bright advertisement can only be issued in given ad position, and playback terminal will do it check and correction verifying
4) the signature ciphertext and binding logo of playback terminal verifying advertisement, can not match and will be deleted the advertisement, even pass through
Verifying, if video format is not met, can also be deleted
5) need to carry out ad distribution really in the case of if cloud service can not be connected, it is also desirable to which advertising user is first completed extensively
Audit is accused with after binding requirement, advertisement has been audited in load from cloud using proprietary mobile storage disc, and it is automatic to be inserted into playback terminal
Complete publication.
