Abstract
A digitization experiment system of a data acquisition unit with a universal serial bus (USB) port comprises a plurality of independent juxtaposed sensors which connected with one end of the data acquisition unit. The other end of the data acquisition unit is connected with a personal computer (PC) through a USB port. Accordingly, the sensors cannot only have sensory abilities, but also have independent communication abilities, thereby being capable of directly communicating with the personal computer and achieving effects of hot plugs and timely sampling of the sensors based on high performances (high in transmission rate, capable of supporting hot swappable and plug and play) of a USB communication.
Description
Technical field
The utility model relates to the teaching and experiment equipment that a kind of laboratory is used, and relates in particular to a kind of digital experiment system that has the data acquisition unit of USB interface.
Background technology
The various digital experiment system that usually adopt in the experiment field is all by using a shared data collector to form in the set of sensors of a plurality of different purposes.Because a plurality of sensors all are to link to each other with PC by the shared data collector, this has just caused when removing or adding sensor all will close shared collector power supply, will avoid causing the sensor loss like this.All will close shared collector power supply when removing or add sensor also is the net result and the classroom efficiency that can counteract and influence experiment to other sensors.
When being transferred to personal computer by a collector during information of same that a plurality of sensors obtain, influenced message transmission rate because of passage is narrow, make the real-time of image data can not get ensureing, especially when running into the data of gathering variation at a high speed, must adopt the method for quasi real time collection, promptly the data storage that earlier sensor is obtained is in collector, every a period of time again property send into personal computer and handle, the display speed of data obviously lags behind acquisition speed, easily make the experimenter produce illusion, influence experiment effect, nor be beneficial to the ability that the performance sensor obtains experimental data and personal computer high speed processing video data at a high speed.With the bridge of shared data collector, in case breaking down, the shared data collector will make the paralysis of a whole set of experimental facilities, so more can enough data acquisition units very important as each sensor and personal computer communication.
Data acquisition unit and PC link very inconvenient.
Summary of the invention
At above-mentioned defective, the utility model discloses a kind of digital experiment system that has the data acquisition unit of USB interface, can effectively solve present domestic and international product of the same type and not support the problem that sensor hot plug, data transmission efficiency are not high and reliability is limited to.
The utility model discloses a kind of digital experiment system that has the data acquisition unit of USB interface, described digital experiment system comprises the sensor that a plurality of independences are arranged side by side, described sensor is connected with an end of data acquisition unit, and the other end of data acquisition unit connects PC by USB interface.
Described sensor is provided with two at least; Sensor in a plurality of different purposes concentrates on a shared data collector, the other end of described shared data collector adopts USB interface, make sensor not only have perception, also has autonomous ability to communicate, can be directly and the personal computer communication, obtain the effect of sensor hot plug and real-time sampling based on the high-performance (the transfer rate height is supported hot plug and plug and play) of USB communication.
Personal computer generally has a plurality of standard USB interface and expanding USB interface, so that this sensor is connected with computing machine is very convenient, and the working sensor power supply can take from the USB interface of personal computer, so a whole set of experimental system distribution source in addition.
Description of drawings
Fig. 1 is a kind of digital experiment system architecture synoptic diagram that has the data acquisition unit of USB interface;
Embodiment
Below in conjunction with accompanying drawing the utility model is carried out detail analysis and explanation.
A kind of digital experiment system that has the data acquisition unit of USB interface, sensor in a plurality of different purposes concentrates on a shared data collector, the other end of described shared data collector adopts USB interface, make sensor not only have perception, also has autonomous ability to communicate, can be directly and the personal computer communication, obtain the effect of sensor hot plug and real-time sampling based on the high-performance (the transfer rate height is supported hot plug and plug and play) of USB communication.
Personal computer generally has a plurality of standard USB interface and expanding USB interface, so that this sensor is connected with computing machine is very convenient, and the working sensor power supply can take from the USB interface of personal computer, so a whole set of experimental system distribution source in addition.
The sensor of various different purposes as shown in Figure 1 can be connected on the shared hub as required, and the other end of hub adopts USB interface directly to be connected with personal computer, can insert at any time or withdraw from, and is independent of each other, and supports hot plug.Make data connector be connected convenience particularly with PC.
