ZH-ZJT type shock reflex system I. Overview ZH-ZJT type shocked to sudden strong stimulation of the reflex response and data analysis system for research animals, a computer can control 1 ~ 5 shocked reaction tank, noise exposure can be added simultaneously 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 analysis statistical parity in the results. Data can be imported Excel, SPSS statistical convenience. Second, the technical parameters 1, the weight sensor selection and setting (1 ~ 2kg) 2, using the main controller card + device control mode 3, the function of the device control card (1) can accept commands from the host controller, the sound and, Start with a stop light, electricity, gas, (2) can be collected 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, receiving instruction PC for data acquisition, sound and light electric start with a stop (2) can communicate with the device controller (3) can simultaneously control four devices control card, and work independently 5, and PC software interface (1) provides a graphical interface data acquisition, waveform display (4-channel) (2) provides acquisition parameters setting 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 Dll OCX or modular design. 6 using Visual studio.net2003 development platform, the technical indicators (1) sound stimulus intensity: 85 db, 95 db, maximum 130 db, can be set by software; acoustic stimulus 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) The data requirements through software, communication 16 A / D digital signal (7) PC and the next crew of USB interface mode (8) Data collection: start stimulation, the animal response latency, highly reactive animals, animal reaction time, collecting animal sounds decibels (9) can be flexibly configured stimulation: such as sound, light, electricity, combined, etc.
