Above-mentioned multi-channel master-slave nuclear thing position monitoring device, described master controller adopt DDZ to insert the road, are serial communication between described master controller and each passage, and described detector is the Geiger counter tube that links to each other with shaping circuit.
Above-mentioned multi-channel master-slave nuclear thing position monitoring device, that described channel controller adopts is AT89C4051, described channel controller device links to each other with the expansion relay with described signal transformation circuit.
Above-mentioned multi-channel master-slave nuclear thing position monitoring device, described display part comprises PS7219 display chip and high-brightness LED charactron and dichromatic LED, described storer is the 24C02 storage chip.
Above-mentioned multi-channel master-slave nuclear thing position monitoring device, described master controller adopts 89C52.
This technical scheme has following beneficial effect:
1. the present invention adopts the design of multimicroprocessor, the system that makes has remarkable advantages aspect parallel processing and the real-time image data, can improve the stability and the reliability of system greatly, especially for the system of function complexity, the design of a plurality of microprocessors more can show the obvious superiority of giving vent to anger.
2. the DDZ of the utility model employing inserts road formula structure and intensification control and treatment technology, a plurality of microprocessor concurrent workings, and significantly the advantage of raising enforcement image data has reduced single microprocessor to the pressure between data analysis, processing, the demonstration.
3. the utility model can adopt the distributed system based on MCS-51, form by a master controller and a plurality of channel controller, the serial communication of master-slave mode is adopted in message exchange between master controller and each passage, master controller can be taken turns continuous query to each passage, and each channel controller is only made a response to the instruction that this passage is correlated with.
4. be provided with main control part in the utility model, can show the real time data and the alarm condition of each passage, the parameter preset of each passage is made amendment and stored.
5. in the utility model channel controller is housed, the system monitoring gamma intensity is independently carried out by each channel controller and finishes, the signal that probe transmits is handled through the microprocessor that shaping offers each sense channel, the microprocessor of each sense channel is converted into the gamma intensity value with the frequency signal that transmits, simultaneously the gamma intensity value that monitors and this passage gamma-rays lower limit intensity level of setting are compared, be higher than when setting permissible value the action of this passage alarm relay.Data acquisition and processing (DAP) between each passage of the present utility model is separate, and parallel carrying out is real-time, has improved the reliability and stability of system greatly.Realize that hyperchannel input, hyperchannel show parallel processing.
6. the utility model adopts Geiger counter tube, its cost is low, temperature effect is little, peripheral circuit is simple, reliable operation, because the detection efficiency of conventional Geiger counter tube is very low, signal capture difficulty under the low radiation dose, the signal statistics fluctuation is very big, the signal that in this product detector is transmitted carries out shaping earlier through 3 reversers, and the signal after the shaping is as the gauge tap of oscillator, by the signal process shaping of oscillator output, offer host process after the driving, after using this processing, make this product can capture feeble signal, improved the sensitivity of instrument.
