ZH-ZJT type shock reflex system I. Overview ZH-ZJT type shock of sudden intense stimuli and data analysis for the study of animal reflex system, a computer can be controlled from 1 to 5 shocked reaction tank, the noise can be added at the same time stimulating light, electricity, gas stimulation, based on user-defined interval given the appropriate stimulus, as well as fear-induced shock response time, latency response, shock amplitude will be displayed and stored for further statistical analysis of parity in the results. Data can import Excel, SPSS statistical convenience. Second, the technical parameters 1, the weight sensor selection and styling (1 ~ 2kg) 2, using the main controller + device control card mode 3, the function device control card (1) can accept commands from the host controller, acoustic, Start with a stop light, electricity, gas, (2) can collect weight sensor signal amplification, and transmitted to the master controller (3) an observation device to configure a device control card 4, the main controller functions: (1) with PC communication, accept instructions PC for data acquisition, sound and light electric start and abort (2) be able to communicate with the device control card (3) can simultaneously control four devices control card, and work independently 5, with PC software interface (1) provides a graphical interface for data acquisition, waveform display (4-channel) (2) provides acquisition parameters settings interface (3) provides real-time data acquisition (Y value) (4) sound and light start time, duration, end time is determined by the host computer (5) signal acquisition start time, duration, end time is determined by the host computer (6) provides OCX or Dll modular design. Development platform using Visual studio.net2003 6, Technical Specifications (1) sound stimulus intensity: 85 db, 95 db, maximum 130 db, can be set by software; acoustic stimulation frequency: can be set by software, 4 ~ 25KHz (2) light stimulus Strength: 2w; light stimulation frequency: can be set by software, the default 60 beats / min (3) electrical stimulation: current intensity 0 ~ 3mA (constant) adjustable (4) Gas (tactile stimulation): by adjusting the air pressure cylinders, Gas output time can be controlled through the software valve (5) sampling frequency: 0 ~ 500KHz, can be set (6) data requirements through software, communication 16 A / D digital signal (7) PC and the next crew USB interface mode (8) Data collection: Start stimulation, animal response latency, highly reactive animals, animal reaction time, collecting animal sounds decibels (9) can be flexibly configured to stimulate ways: as sound, light, electricity, combined, etc.
