The above-mentioned chair and desk for pupils with recognition function, described control device also comprises the drive circuit for driving telescoping mechanism action, and the input of drive circuit connects the output of microprocessor, and the output of drive circuit connects telescoping mechanism.
The above-mentioned chair and desk for pupils with recognition function, described telescoping mechanism is leading screw, hydraulic cylinder or cylinder.
The above-mentioned chair and desk for pupils with recognition function, the backrest of described seat is provided with the chair back for blocking desk table bucket window.
The above-mentioned chair and desk for pupils with recognition function, the cross section of described line slideway is T-type structure, and sliding in T-shaped line slideway is provided with block, and described chair pin is fixedly installed on the upper surface of block.
The above-mentioned chair and desk for pupils with recognition function, the sidewall that described desk is relative with seat is provided with infrared range-measurement system, and the output of infrared range-measurement system connects the input of microprocessor.
Owing to have employed above technical scheme, acquired by the utility model, technological progress is as follows.
The utility model makes tables and chairs put neatly by being arranged on ground guide rail, and can, under guarantee tables and chairs normally use prerequisite, one's own tables and chairs is not separated.The utility model has recognition function, when owner is near tables and chairs, card reader reads the RF radio-frequency card worn with owner and by information transmission to microprocessor, whether the information that microprocessor judges receives is consistent with the information of setting, if consistent, then controlling telescoping mechanism drives seat to move to the direction away from desk, facilitates owner to take a seat; If inconsistent, then seat does not move, and other people cannot take a seat.When owner does not use, card reader cannot read RF radio-frequency card information, and microprocessor then controls telescoping mechanism and drives seat return, and the window of desk table bucket then blocks by the chair back on backrest, and the study article in protection desk table bucket, prevents it from losing.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model;
Fig. 2 is the top view of line slideway described in the utility model;
Fig. 3 is the electrical principle block diagram of control device described in the utility model.
Wherein: 1. desk, 2. seat, 21. chair back, 22. chair pin, 23. blocks, 3. guide rail, 31. frame type guide rails, 32. line slideways, 4. telescoping mechanism.
Detailed description of the invention
Below in conjunction with the drawings and specific embodiments, the utility model is further elaborated.
Have a chair and desk for pupils for recognition function, its structure as shown in Figure 1, comprises desk 1, seat 2 and guide rail 3, and guide rail is inlaid on ground, classroom, and the table pin of desk 1 and the chair pin of seat 2 are all arranged in guide rail 3.The backrest of seat is provided with the chair back 21, the area of the chair back is corresponding to the area of desk table bucket window, is of use not only in when using tables and chairs and facilitates student to lean on, also for blocking desk table bucket window when not using tables and chairs.
The structure of guide rail 3 as shown in Figure 1, comprises a frame type guide rail 31 and two line slideways 32, and four corners of frame type guide rail 31 are used for clamping desk pin; Article two, line slideway 32 be arranged in parallel, and not only for clamping chair foot, also for leading to chair motions, one end of line slideway 32 is stretched in frame type guide rail, and is fixedly connected with frame type guide rail, and the other end extends back.
One end that line slideway stretches into frame type guide rail is embedded with telescoping mechanism, as shown in Figure 2, telescoping mechanism for drive seat linearly guide rail seesaw, telescoping mechanism can be any one in leading screw, hydraulic cylinder or cylinder.In the present embodiment, the cross section of line slideway is T-type structure, and sliding in T-shaped line slideway is provided with block 23, and chair pin 22 is fixedly installed on the upper surface of block, for preventing seat run-off the straight in movable process.
Seat is provided with control device, for controlling telescoping mechanism action.Control device comprises RF radio-frequency card, card reader, drive circuit, microprocessor and infrared range-measurement system, the output of card reader is connected with the input of microprocessor respectively with the output of infrared range-measurement system, the output of microprocessor connects the input of drive circuit, and the output of drive circuit connects telescoping mechanism.
RF radio-frequency card is worn on it tables and chairs owner, with tables and chairs master message in RF radio-frequency card; Card reader is arranged on the seat, for reading RF radio-frequency card information, and is transferred to microprocessor; Microprocessor is used for sending control signal according to card reader information to drive circuit, and drive circuit is used for driving telescoping mechanism action under the instruction of microprocessor.
Infrared range-measurement system is arranged on the desk sidewall relative with seat, for responding to the distance on tables and chairs owner distance desk side edge, and is transferred to microprocessor.
Operation principle of the present utility model is as described below.
When tables and chairs owner is near tables and chairs, card reader reads the RF radio-frequency card worn with owner, and by information transmission to microprocessor, whether microprocessor judges is consistent with the information of setting, if consistent, then control telescoping mechanism and drive seat to move to the direction away from desk, facilitate owner to take a seat; If inconsistent, then seat does not move, and other people cannot take a seat.
Tables and chairs owner is after taking a seat, infrared range-measurement system detects the distance L between owner and desk, and be transferred to microprocessor, when this distance L is larger than the gauged distance Le of setting, microprocessor drives seat to move to desk by controlling telescoping mechanism, until L and Le is equal, tables and chairs owner just can have suitable position to enter learning state.
When tables and chairs owner leaves tables and chairs, card reader cannot read RF radio-frequency card information, and microprocessor then controls telescoping mechanism and drives seat return, and the window of desk table bucket then blocks by the chair back on backrest, the study article in protection desk table bucket.
