Description

A kind of various modes industrial computer that receives

Technical field

The utility model relates to the industrial computer field, particularly be a kind of various modes industrial computer that receives.

Background technology

Industrial computer is widely used in industry or fields such as security protection, fire-fighting such as monitoring and alarming system, fire alarm system.But traditional monitoring-controlling system signal collection mainly through wired or wireless power receive mode, can not be satisfied control technology requirements such as intellectuality, modularization, telecommunication.

The utility model content

The purpose of the utility model is to overcome above-mentioned deficiency, and a kind of various modes industrial computer that receives is provided.

The utility model solves the technical scheme that its technical matters adopted: a kind of various modes industrial computer that receives; Comprise GSM short message receiving-transmitting circuit, wireless transceiver circuit, central processing unit, warning circuit and RS485 communication interface circuit, the output signal of said GSM short message receiving-transmitting circuit and wireless transceiver circuit exports warning circuit and RS485 communication interface circuit to through central processing unit control.

Radio transmitter that the resistance R 5 that said wireless transceiver circuit is connected by K switch 1 output terminal successively, triode Q2, FDD-5 transmitter module U3 form and the loudspeaker Y that is connected by JDD-5 receiver module U2, JDD-5 receiver module U2 output, the wireless receiving circuit that LED 1 is formed constitute.

Said central processing unit adopts the 89C51 single-chip microcomputer.

Said RS485 communication interface circuit is connected to the COM end of PC through the output terminal of 75176 communication interface chip IC2.

Through adopting above-mentioned technical scheme; The beneficial effect of the utility model is: this industrial computer adopts GSM short message receiving-transmitting circuit acquisition controlling command signal, wireless module receiver module circuit to receive the remote signal command signal; After central processing controller judgement conversion; Be sent to PC through the conversion of RS485 telecommunication circuit, show the current information state, realize that multiple interfaces warning transmission receives control model by PC; The difficult technical barrier of the integrated coupling of resolution system is effectively saved the engineering cost cost greatly, is had random setting, the intelligent control function of reception, monitoring, warning.

Description of drawings

Fig. 2 is the circuit theory diagrams of the utility model.

Embodiment

Like Fig. 1, shown in Figure 2; A kind of various modes industrial computer that receives of the utility model; Comprise GSM short message receiving-transmitting circuit 1, wireless transceiver circuit 2, central processing unit 3, warning circuit 4 and RS485 communication interface circuit 5, the output signal of said GSM short message receiving-transmitting circuit 1 and wireless transceiver circuit 2 exports warning circuit 4 and RS485 communication interface circuit 5 to through central processing unit 3 controls.

The 35th, 37,38,39 pin that are connected to 89C51 single-chip microcomputer IC1 by GSM short message transceiving module U1 etc. are formed GSM short message receiving-transmitting circuit 1; Form RS485 communication interface circuit 5 by the 32nd, 10,11 pin of 89C51 single-chip microcomputer IC1 and 75176 communication interface chip IC2, resistance R 3 etc.; When needs send warning message when instruction to the PC control system; Send " message code or word content " through handset short message platform to GSM chip SIM phone number, GSM short message transceiving module U1 receives external warning message, after GSM short message transceiving module U1 inter-process; To 89C51 single-chip microcomputer IC1 data signal; After 89C51 single-chip microcomputer IC1 internal processes is comprehensively judged decoding, to 75176 communication interface chip IC2 communications of control data information, send signal to PC through 75176 communication interface chip IC2 by 89C51 single-chip microcomputer IC1; Receive decoding by the PC configuration software and show current warning message; Thereby timely efficiently and effectively guiding operation operator on duty to the timely processing of warning message, strives for the very first time.

Radio transmitter that the resistance R 5 that said wireless transceiver circuit 2 is connected by K switch 1 output terminal successively, triode Q2, FDD-5 transmitter module U3 form and the loudspeaker Y that is connected by JDD-5 receiver module U2, JDD-5 receiver module U2 output, the wireless receiving circuit that LED 1 is formed constitute.When pressing K switch 1, through the R5 current limliting, make triode Q2 conducting, be input to the 2nd pin of FDD-5 transmitter module U3, and deliver to its 3rd pin CP modulation signal input end, the high-frequency signal of emission is modulated.Antenna is promptly launched modulated frequency electromagnetic waves to JDD-5 receiver module U2.When JDD-5 receiver module U2 receives the high frequency electromagnetic wave signal of FDD-5 transmitter module U3 emission; The 4th pin CPA audio signal output end of JDD-5 receiver module U2 directly drives common electrical dynamic formula loudspeaker Y and sends the sound, and its 2nd pin output high level signal makes LED 1 get electroluminescence; The 34th pin I/O end that is connected to 89C51 single-chip microcomputer IC1 simultaneously also is high level state; After 89C51 single-chip microcomputer IC1 internal processes is judged, to send out two-way and send control signal, the first via is exported by 89C51 single-chip microcomputer IC1 data signal; Send signal through 75176 communication interface chip IC2 to PC, receive decoding by the PC configuration software and show current warning message; The 4th pin output low level signal of another route 89C51 single-chip microcomputer IC1 through resistance R 2 current limlitings, makes triode Q1 conducting, promote the news Chinese percussion instrument YD send " ticking ... " Alarm sound, remind the processing of operator on duty to warning message.

An above-described preferred embodiment that is merely the utility model can not limit the scope that this practicality is implemented, and every equalization of being done according to the utility model claim changes and decorates, and all should still belong in the scope that the utility model contains.
