Description
Equipment overview
The industrial sensor application and testing equipment is a training platform that is close to the real industrial field sensor debugging application. The sensors used on the equipment are all industrial sensors, and the signal detection points on the equipment are completely generated by the actual operation of the industrial control object. Students can install and debug the sensor circuit at the approximate industrial debugging site, so that students can vividly and deeply understand the use occasions and detection application conditions of various sensors in the industrial site, and train students on the application selection and failure of industrial sensors Analysis and diagnosis capabilities, etc.
The industrial sensor application and testing equipment adopts a block-type modular structure. Each industrial control object and control unit are connected to a safety socket, and a wire with a safety plug is used for circuit connection. It can be used alone or combined with a dedicated interface module to complete the controller. control function. Various industrial control objects use many types of industrial sensors including: displacement sensors, color mark sensors, vision sensors, optical fiber sensors, photoelectric sensors, proximity sensors, temperature sensors, liquid level sensors, pressure sensors, etc. Covers most of the sensors used in the industrial field. At the same time, the equipment is equipped with an IoT sensor expansion unit, including PM2.5 and air quality sensors, air and soil temperature sensors, carbon dioxide sensors, etc.
At the same time, the device is equipped with a single-chip digital control interface module with high reliability and stability, with 8 optically isolated digital signal inputs, which can be used to detect various external switch signal inputs, and 8 optically isolated digital signal outputs. 2-channel output current: 0-20mA, error <0.5mA; 2-channel output voltage: 0-10V, error ±0.2V, 2-channel measurement current: 0-20mA, error <0.5mA; 2-channel measurement voltage: 0-10V ,The error is ±0.2V. At the same time, the interface module provides the host computer software that matches the company’s equipment. Through human-computer interaction, the sensors on each industrial control object can be collected to the host computer, or the sensor can be simulated and debugged through the host computer. Work, it is convenient for students to carry out various testing and debugging training tasks according to the learning stage. At the same time, the bottom layer of the interface module of the MCU is open, and students can carry out in-depth study and basic MCU training according to actual needs.
The industrial sensor application and testing equipment power station is equipped with an AC power control unit: the three-phase four-wire 380V AC power supply supplies power to the device after the air switch. The device is equipped with power supply and power-on instructions, with lighted fuse protection, start-stop switch control, and leakage alarm at the same time Indication and alarm reset, and with emergency stop switch. Provide one set of three-phase four-wire 380V, single-phase 220V power supply (safety socket), and provide two sets of three-plug AC200V sockets, which are controlled by the start-stop switch and set with fuse protection. DC power supply, DC voltage/ammeter, logic level output and indication, etc.: DC voltage: 0～±10V adjustable output; DC current: 4～20mA adjustable output; DC digital voltmeter/ammeter: voltmeter range 0～30V , Accuracy 0.5, ammeter range 0-30mA, accuracy 0.5; at the same time, there are logic level output (inching, yellow, green and red three color switches), logic level indicator (yellow, green and red three color indicators), LED digital tube, selection Switch, buzzer, DC 24V relay, DC voltage output: 24V/6A, 12V/2A each set (with fuse protection).
