Sensor and detection technology experiment table,Tr--ning device of fire hydrant fire extinguishing system

1. Experimental table composition

The sensor and detection technology experiment table consists of six parts: the m--n console, vibration source, temperature source, rotor source, sensor and corresponding experimental templates, data collection cards and processing software, and experimental table tables.

1. The m--n console part

Provide high -stable ± 15V, + 5V, ± 2V ~ ± 10V adjustable, + 2V ~ + 24V adjustable eight types of DC voltage voltage power supply; the m--n control table panel is also equipped with voltage, frequency, and speed display. Audio signal source (audio oscillator) 1kHz ~ 10kHz (adjustable); low -frequency signal source 1Hz ~ 30Hz (adjustable); --r pressure source 0-20kPa adjustable, digital voltage table: 0-20V, high accuracy; frequency/speed speed; Table: frequency of 1 ~ 9999Hz, speed of 1 ~ 9999rpm; timer: 0-9999s, accurate to 0.1S; high -precision temperature regulatory instrument (control temperature accuracy ± 0.5 ° C); RS232 computer serial interface.

2. Three source boards

Heating source: 0 ～ 220V AC heating, temperature control at room temperature ~ 150 ℃; rotating source: 2 to 24V DC driver, speed adjustment of 0 to 3000rpm; vibration source: vibration frequency 1Hz ～ 30Hz (adjustable), resonance frequency around 12Hz Essence

3. LabView data collection card and processing software:

Data collection and interface parts adopt a USB interface to facilitate the actual use of users. The collector can meet the complete experimental requirements, replace the existing instrument display reading, and can also be used as a direct scientific research and development of scientific researchers. The specific technical indicators are as follows:

1) 3 channels 16 -bit input, ** clamp ± 20V, must be achieved, in order to prevent burning channels. *** Small resolution 1mV, continuous ** sampling frequency 100kHz, the curve must be smooth. M--ntenance Electric Electronics and Occupational Qualification Tr--ning Evaluation Simulation Software (provides copyright certificates and demonstrated on -site): This software is the format of the APK, which can be used on the PC side, or on the mobile terminal. Set up faults. The green box in this software selects manually setting the fault point (*** can set 39 fault points). You can also automatically perform a random f--lure point settings through the system. Three fault points settings, random four fault points settings, random five fault points settings. This software has a toolbox, component library, magnifying glass, circuit diagram and other functions. You can choose a multimeter to detect through the toolbox. The appropriate element can clearly understand the components and circuits by magnifying the mirror. This software starts the control circuit f--lure setting through the motor star triangle, and has been investigated to allow students to understand the working principle and circuit structure of the motor star triangle to start the control circuit.

2) All sensor experimental sampling and control software must be collected and controlled with LabView. Software acquisition settings can be sampled, timed sampling, two -way sampling, and dynamic sampling. In a single -step sampling, you can analyze its ** non -linear error or ** stagnation error in a single -step sampling method. In dynamic experiments, the frequency, amplitude, or speed of the input waveform can be analyzed during dynamic experiments. Support printing function, you can print the experimental results after the experiment is over. Collecting card hardware has a program control amplification function, and can be highly accurate when measuring small voltage. The resolution is 1MV. Students can program and debug themselves by themselves.
