Embodiment
Understand the utility model in order to clearer, be described in detail below in conjunction with accompanying drawing:
As shown in Figure 1, the utility model adopts the C8051F341 microprocessor of SiliconLabs company, this microprocessor is fully-integrated mixed signal SOC (system on a chip) type MCU, having electrification reset in sheet, VDD monitor, voltage adjuster, WatchDog Timer and internal clock oscillators function, is the SOC (system on a chip) that really can work alone.The inner integration USB controller of this processor, does not need to increase USB interface chip in microprocessor outside, greatly simplifies circuit design.In addition, this monitor also comprises industrial computer re-starting control circuit, crystal oscillator, house dog, indicator light circuit.Monitor working power is provided by USB interface by industrial computer, or by DB9 line directly from the power taking of industrial computer internal switch power supply.
As shown in Figure 2, the industrial computer re-starting control circuit of intellectual monitoring device adopts the relay of single-pole double-throw (SPDT) to realize.Two signal wires (RESET1, RESET2 signal) that industrial computer is restarted are connected to the public pin (1 pin of K1) of monitor relay respectively and often open pin (3 pin of K1).When intellectual monitoring device detects that industrial computer crashes, microprocessor driven relay closes, industrial computer Restart Signal RESET1 and RESET2 conducting, industrial computer is restarted.
Native system working principle of hardware: C8051F341 microprocessor is a fully-integrated mixed signal SOC (system on a chip) type MCU, is whole control circui core.Crystal oscillating circuit is the concussion waveform of 12MHz for generation of frequency, as the work clock of microprocessor.Watchdog circuit is used for monitoring microprocessor duty, flies the microprocessor that can reset, ensure processor functional reliability when microprocessor program runs.Indicator light circuit is used for the instruction of monitor duty.USB circuit provides usb communication bus, for the transmission of monitor and industrial computer data, instruction.Industrial computer restarts driving circuit after monitor monitors crashes to industrial computer, produces control signal control industrial computer and restarts.
As shown in Figure 2, this functional circuit employing relay realizes the function that industrial computer is restarted.When intellectual monitoring device control industrial computer is restarted, microprocessor is in RESET signal output low level, and triode Q1 conducting, has electric current to pass through in relay K 1 coil, relay closes, and industrial computer Restart Signal RESET1 and RESET2 conducting, industrial computer is restarted.
As shown in Figure 3, USB interface is for inserting USB cable, and LED is pilot lamp, and DB9 is DB9 male socket, for inserting industrial computer reset signal and power supply connection cable.
As shown in Figure 4, be connected between monitor with industrial computer by two cables, one is USB cable, transmits for usb communication.Another is DB9 cable.
