Description
[technical field]
The utility model relates to a kind of digital circuit and microprocessing systems development board of the usefulness of imparting knowledge to students.
[background technology]
Present stage, each school all offered the Digital Electronic Technique experiment, and generally speaking, school all can adopt the mode of computer analog or object operation to do experiment.
The object operation mode promptly is to adopt digital circuit board to carry out operation experiments, and the employed digital circuit plate bulk of school is all bigger at present, carry inconvenience, and function ratio is less, and cost is bigger; In addition, in experimentation, need be inserted into the pin on the lead in the corresponding jack; Draw experimental data through control then, but the time of usefulness grown, the loose contact between pin and the jack will appear; This bad when the inspection fault, be difficult to inspection and come out.
[utility model content]
The purpose of the utility model is the deficiency that is to overcome prior art, provide a kind of easy to carry, function is many, uses economical and practical and digital circuit and the microprocessing systems development board of guaranteeing to test stability.
In order to solve the technical matters of above-mentioned existence, the utility model is taked following technical proposals:
A kind of digital circuit and microprocessing systems development board; The power supply area, the signal that comprise pcb board and be located at above it produce district, logic pen district, transfer district, test block, voltage to frequency test section, level viewing area, digital display area and logic level generation district; On described transfer district and test block, be provided with a series of matrix sockets; On described socket, be provided with the jack that can be connected with lead; On described pcb board, also be provided with matrix series district, single-chip microcomputer district, music generation district and peripheral control zone; Be provided with connector and pass and the pin corresponding with jack from connector inside at described lead one end, described pin can be connected in the connector slides within and with making its elastic component that resets.
In to above-mentioned digital circuit and microprocessing systems development board improvement project, described elastic component is a spring.
In to above-mentioned digital circuit and microprocessing systems development board improvement project, the single-chip microcomputer in the described single-chip microcomputer district is universal DIP plug wire single-chip microcomputer.
Compared with prior art, the beneficial effect of the utility model is: 1) because it is integrated in each function element on the pcb board, so its volume is little, be convenient for carrying; 2) function is many, uses economical and practical; 3) in addition; When being inserted into pin in the jack; Elastic component will produce a downward pressure to pin, can guarantee that like this pin contacts with the hard contact of jack bottom all the time, the situation of loose contact can not occur; Thereby guarantee the stability of testing, greatly reduce the probability that inspection is fixed a breakdown.
Below in conjunction with accompanying drawing and embodiment the utility model is further specified:
[description of drawings]
Fig. 1 is the structural representation of the utility model;
Fig. 2 is the connector synoptic diagram of the utility model;
Fig. 3 is the cut-open view of the utility model connector.
[embodiment]
A kind of digital circuit and microprocessing systems development board; The power supply area 2, the signal that comprise pcb board 1 and be located at above it produce district 3, logic pen district 4, transfer district 5, test block 6, voltage to frequency test section 7, level viewing area 8, digital display area 9 and logic level generation district 10; On described transfer district 5 and test block 6, be provided with a series of matrix sockets 11; On described socket 11, be provided with the jack 111 that can be connected with lead; On described pcb board 1, also be provided with matrix series district 13, single-chip microcomputer district 14, music generation district 15 and peripheral control zone 16; Be provided with connector 12 and pass from connector 12 inside and the pin 121 corresponding with jack 111 at described lead one end, described pin 121 can be connected at connector 111 internal activities and with making its elastic component that resets 122; When using the utility model, behind the access power supply, signal produces district 2 will provide pulsed operation, and the effect of monitoring power supply district 2, signal generation district 3 and test block 6 is played in described voltage to frequency test section 7; In experimentation; Experimental needs; On test block 6 through being inserted into the pin on the lead 121 in the corresponding jack 111; Whether correct, restart logic level and produce the 10 li corresponding switches in district if coming the circuit in test experience district 6 to connect through logic pen district 4 then, will be bright at the corresponding pilot lamp of level viewing area 8; Digital viewing area 9 will demonstrate the data that experiment draws, and the single-chip microcomputer 141 in the described single-chip microcomputer district 14 can be controlled peripheral control zone 16 and connect the external machine (mainly being the control lathe) of coming in from the external world; Because it is integrated in each function element on the pcb board, so its volume ratio is less, and function is many; Use both economical material benefit, in addition, when being inserted into pin in the jack; Described elastic component will produce a downward pressure to pin, can guarantee that like this pin contacts with the hard contact of jack bottom all the time, even the time of using has been grown; Can guarantee that also pin contacts with the hard contact of jack bottom, the situation of loose contact can not occur.Said above comprehensive, the utility model be a kind ofly be convenient for carrying, function is many, uses economical and practical and digital circuit and the microprocessing systems development board of guaranteeing to test stability.
In the present embodiment, described elastic component is a spring, also can be other elastic constructions, as long as pin is resetted.
In the present embodiment, the single-chip microcomputer 141 in described single-chip microcomputer district 14 is universal DIP plug wire single-chip microcomputers, so just can control more external controller, and usable range is more extensive.
