Description

I. Product introduction

YL-1021A sensor and inspection technology experiment platform is a product we dedicated in R&D for years. Base on sensor technology lecturing experiment devices, we develop this product in order to meet the demand for various sensors, multiple levels of requirements.

Sensor and inspection technology is one of the most important part in modern technology. Sensor is the critical device for data extraction, data conversion, and data processing.

Sensor and inspection technology extract data from nature, society, production process, and scientific experiments, such as pressure, weight, velocity, humidity, and etc.; Via corresponding sensor modules, the collected data can be converted into transferable, visual, and other processible information. The purpose of data processing is to process, calculate, analyze, and integrate the obtained data, in order to display, alarm, predict, measure, protect, control, dispatch, and manage target subjects.

YL-1021A Sensor Technology and Inspection Practical Training Device is not only a practical training device, but also a complex device. The complexity includes its sensor Technology, data processing, electronic technology, SCM technology, and wireless technology theories and skill trainings.

Its advantage is that:

1．It can adopt to different majors, and we also make customized experimental modules.

2．It can adopt to the development trend. As the information extraction tool, sensor development is fast, we can follow up the development and support with new sensor model and experiment modules.

3．Instructor and students can develop new experiments, and we can help with it.

4．User can implement the device for course development, senior design, and self-made device.

YL-1021A Sensor Technology and Inspection Practical Training Device is designed for vocational schools and technical colleges, specifically intended for courses such as Sensor Theory and Technology, Automated Inspection Technology, Non-Electrical Measurement Technology, Industrial Automated Panel and Controls, Parameter Electrical Measurement Mechanical, and etc.

YL-1021A Sensor Technology and Inspection Practical Training Device primarily uses transparent educational sensors for observation purpose, but the structure and wiring is the same as industrial sensors.  We hope the experiment can help enhance students’ comprehension of text book knowledge, and in the meanwhile, obtain the skill of data extraction, conversion, and analysis as a scientific worker.

5. Integrate with NI plug-and-go devices, we can use NI LabVIEW to perform graphical programming. Students can use all software to experiment and practice.

3.1 Sensor module composition

A sensor can convert a measured non-electric quantity into a electric quantity output, thus it has to have a component to “feel” the deviation of the non-electric quantity. However, not all non-electric quantity are convertible to electric quantity, but it might be easier to convert non electric quantity into an intermediate non electric quantity. This function component is call sensitive component (a.k.a. Convector) in a sensor. For example, strain gauge pressure transducer converts pressure signal into voltage signal output, its sensitive component is an elastic diaphragm, it converts the pressure into the deformation of the elastic diaphragm.

The component converts the intermediate non-electric quantity output into electric quantity of the sensitive component in the sensor, is called converter component (or converter). It implements physical, chemical, biological or other effects to achieve this purpose. For example, the converter of strain gauge pressure transducer is a strain gauge, it implements the resistance strain effect (the resistance of metal or semi-conductor is influenced by its magnitude of mechanical deformation), to convert the deformation into the value change of resistance.

Sensitive component is the part that directly “feel” or respond to measured parts; converter converts the “feeling” of sensitive component or response to the measured parts into transmittable and measurable electric signal. Be aware that some measure non-electric quantity can be converted into electric quantity directly. In this case, the sensitive component and converter merges into one component. For example, thermo resistor temperature sensor utilizes platinum resistor (PT100) or copper resistor (Cu50), directly output the measured temperature signal into resistance value.

The output electricity of converter component usually difficult to be shown, recorded, processed nor controlled. In this case, we would like to convert the electricity into electrical signal. The part responsible for this function in sensor is called measuring circuit. Measuring circuit is also called signal regulation and conversion circuit, it converts the sensor component output electrical signal to convenient display, record, process, and control signal. For instance, there is a bridge as measuring circuit in strain gauge pressure transducer, it can convert strain gauge pressure transducer signal into a voltage signal, which can be recorded, and displayed via a magnifier. The choice of measuring circuit accords with converter component type. The common types are bridge circuit, PWM circuit, oscillating circuit, and high impedance input circuit.

In summary, a complete sensor circuit is consisted of 4 parts: sensitive component, converter, measuring circuit, and auxiliary power. Shown as figure below. Among which, the sensitive component and converter can merge to one component, and some sensor does not require auxiliary power.

3.2 Wireless communication sensor network

In many cases, sensors are supposed to be placed in target location for data collection, thus wireless transmission capability is mandatory for these sensors.

This device is equipped with 3 wireless communication modules: Zigbee, Bluetooth, and Wi-Fi. It can respond to corresponding sensor wireless communication network.

Sensor wireless communication network is primarily composed of AD converter, transmission component, receiving component, and host computer. System structure shown in the figure below:
