Embodiment
Please refer to shown in Fig. 1, which show the concrete structure of the preferred embodiment of the utility model, a kind of 24L Control card, include in order to all SMD electronic components PCB 10 and the STC chip 20 with data protection function that is installed in PCB 10, Xiao with extremely short function reverse recovery time holds based diode 30, in order to drive the triode 40 of relay, in order to prevent the optocoupler 50 of the noise after relay switch, resistance capacitance 60, in order to the crystal oscillator 70 of accurate timing, in order to the three-terminal voltage-stabilizing chip 80 of lowering and stabilizing blood pressure effect in DC circuit, in order to the break-make light emitting diode 90 of display circuit and the PCB circuit for each electronic component is electrically connected.
Described PCB circuit size is 215MM*91MM.
Described PCB circuit includes 12V input circuit, 12V output circuit and 232/485 communication switching circuit 100.
Described STC chip is STC351-PDIP40 chip; Described STC chip includes program's memory space and data space, has data protection function, and during unexpected power-off, data can not be lost.
Real-time clock module is provided with in described crystal oscillator.
The principle of work of this 24L Control card is as follows:
First access 12V direct-flow input circuit, power to Control card, at this moment starting pilot lamp can light, if STC chip now own burning program, so now communication pilot lamp also can be lighted.12V direct current changes into 5V voltage enter three-terminal voltage-stabilizing pipe voltage stabilizing step-down after inductance and capacitor filtering after, and to STC chip power supply, crystal oscillator is to the timing of STC chip simultaneously, then by adhesive and the disconnection of STC chip controls 24L relay.The output terminal of 24L Control card connects a pin of relay.Another pin connects a wherein road of 24L, now STC chip sends a signal to optocoupler, optocoupler is except after noise, triode is controlled after resistance, the adhesive of relay is determined by transistor switching circuit, wherein during adhesive, the reverse recovery time of schottky diode is extremely short, and such relay is wanted can milli free from errors adhesive disconnection.
This 232/5 PORT COM, is connected with computer, therefore need convert 232 signals to and could connect computer.
This light emitting diode can observe circuit, and with dodging the go out adhesive and disconnection that reflect relay intuitively, facilitates testing circuit.
This 24L Control card controls solution for the disconnection adhesive of 12V relay specially, relay is driven with triode, interference is removed with optocoupler, by STC chip, thus carry out the 24 non-interfering operations in tunnel, rely on chip program and powerful function accurately, for relay provides the control program of high-level efficiency, high stability and full-automation.Be widely used in the opening and closing of network remote monitoring power plant, automated workshop, remote machine room light, the power supply that opens the light, audio frequency, video and electronic gate, save the hardship of manpower passes, thus save human resources.
The above, it is only preferred embodiment of the present utility model, not technical scope of the present utility model is imposed any restrictions, therefore every according to technical spirit of the present utility model to any trickle amendment made for any of the above embodiments, equivalent variations and modification, all still belong in the scope of technical solutions of the utility model.
