Description
Technical field
The present invention relates to remote supervisories to examine technical field, and in particular to the long-range visit of OSCE Objective Structured Clinical Examination
Ask system.
Background technique
The concept of Objective Structured Clinical Examination by Ronald doctor Harden of Britain et al. in 1975 propose,
The basic thought of OSCE is " test based on operating ", alive as a kind of method of objective evaluation clinical skill
The many countries and regions in boundary widely use.Chinese OSCE is applied to Training Residents and skill examination, it is therefore intended that reinforcement is faced
The culture of bed doctor's clinical operational skill is quality-oriented education in General Practice Education to adapt to the needs of society and talents market
In it is specific implement.With the development of society and the transformation of medical model, simple specialized health service system has been difficult to maintain.
The general family medicine talent for possessing high quality adaptive type is the direct embodiment of comprehensive hospital strength.Promote and apply OSCE, attention to training
The Clinical Thinking Ability and actual operational capacity of medical worker, is conducive to cultivate that large quantities of quality are high, the ability of practice is strong is compound
Medical person.
Its drawback is it must is the progress OSCE examination under a closed space, almost says it is the state of being isolated from the outside
Lower just to can be carried out, the related leader as medical colleges and schools desires to learn about examination process in fact, and can effectively prevent
Only in this process individual teachers to the corrupt practice in examination process.
Summary of the invention
In view of the defects and deficiencies of the prior art, the present invention intends to provide OSCE Objective Structured Clinical Examination

Image frame.
2D WDR wide dynamic, AGC automatic gain compensation function, 3D picture drop are hot-tempered；Integrate can output under low light
The excellent picture of zero interference.
The compensation of BLC rapid backlight, the place to reinforcement brightness effects deficiency
Has the features such as code stream setting, various video crossfire, transmission picture low latency
(6) wireless and network system
S1588GP is the full gigabit PoE Ethernet switch of 8 mouthfuls of all steels, 11 cun of desktop type non-network management of newest release, provides 8
A 10/100/1000M adaptive port RJ45, MDI/MDIX self-turnover is supported in every port, and can realize linear speed
Forwarding.8 ports have the function of PoE, support IEEE802.3at/af standard, can be used as power over Ethernet device, it can be automatic
Ground detects the type of terminal device, and the large power supply provided, big electric current and other electric power ought be had by having short-circuit protection effect
When failure, it powers starting short-circuit function cutting, prevents from burning out equipment and can avoid being caused by line fault or setup error
Network failure, and powered for it by cable.Each port highest output electricity reaches 30W, and transmitting range is up to 100m.
