Summary of the invention
At above-mentioned actual demand, technical matters to be solved by this invention provides a kind of condition monitoring that possesses, and pressure reduction shows, output driving circuit sample and state interlocking duplicate protection, wireless remote control, the bio-safety cabinet intelligent controller of communication function.
The technical solution adopted in the present invention: a kind of biological safety cabinet controller, it is characterized in that: an end of microprocessor connects keyboard circuit, the AD unit, first photoelectric isolating circuit, clock circuit and watchdog circuit, the other end connects the LCD liquid crystal display circuit, expansion interface circuit, memory circuit and communicating circuit, described AD unit connects sensor, described first photoelectric isolating circuit connects limit switch, described expansion interface circuit connects second photoelectric isolating circuit and remote control circuit, described second photoelectric isolating circuit connects output driving circuit, and described output driving circuit connects pressure fan, exhaust blower, the UV device, illumination and expansion of power supply.
Be equipped with second photoelectric isolating circuit between described expansion interface circuit and the output driving circuit, described second photoelectric isolating circuit connects relay by amplifier, and the two ends of described relay are equipped with fly-wheel diode.
Be equipped with pull-up resistor between described expansion interface circuit and the remote control circuit.
The invention has the advantages that described bio-safety controller is based on microprocessor, cooperate relevant functional circuit, operation for Biohazard Safety Equipment on the basis of control operation of original traditional biological safety cabinet and simple logic restriction provides more humane novel concept, specifically comprises:
1, the LCD LCDs can dynamically show air-supply and air draft pressure reduction;
2, the interlocking between numerous can not the operation simultaneously of realization;
2, built-in 24-hour format timing demonstration and stop watch function;
3, blower fan work time timer function determines whether its filtrator needs to change with monitoring safety cabinet service time by safety cabinet service time;
4, uviol lamp working time timer function is with monitoring uviol lamp service time, and estimates that uviol lamp need change the time, can control the ultraviolet disinfection time automatically simultaneously;
Sound and light alarm is arranged when 5, operation window is not fastened,, sound and light alarm is also arranged and the liquid crystal display alarm is arranged if front window is opened above operational height;
6, straighforward operation, the coupling different antennae can realize 5 meters to ten meters straighforward operation;
7, backing up maintenance pattern can be carried out data parameters analysis and fault eliminating to safety cabinet.8, carry out communication with host computer, have ability with computing machine communication and even network monitoring.
The Biohazard Safety Equipment that above numerous function designs all are the no microprocessors of tradition in the past is unexistent.The present invention has overcome the defective of simple logic control; microprocessor programming technique that utilization is advanced and interface driving circuit are realized the control to safety cabinet; adopted the duplicate protection of state interlocking; further realize the automatic protection of BIOLOGICAL CONTROL cabinet; adopted the LCD LCD; real-time environmental data monitoring in the safety cabinet preferably is provided, and abundant warning message and error message is provided.Easy to operate, dependable performance.
