Main function:
Real-time online detection, bar code can be automatically read, automatic measurement, transmission, processing and storage of data, and can meet the mixed production detection of products of different power types; the system can automatically determine the selected relevant characteristic parameters, such as: temperature, Power; output the judgment result and connect it with the assembly line control system to realize automatic shunt control of defective products.
Structure:
Power detection module: Each intelligent wireless dynamic data acquisition box is equipped with a dual-channel power module, and the sampling frequency is adjustable from 1 to 120S. The first three minutes and millisecond-level rapid acquisition can be set to detect parts; the power acquisition module is easy to install, repair and test.
Dynamic data collection box: The size of the collection box is designed to meet the installation requirements of the suspension chain and the number of stations, and the installation is completed in cooperation with the suspension chain manufacturer. The suspension chain and sliding contact line are provided and installed by the wire body manufacturer, with 110V and 220V power cord connectors (ie collectors) reserved, and the spacing is designed according to the number of stations. The dynamic collection box is installed by our side to the wire body manufacturer reserved collectors superior. The dynamic data acquisition box has the function of automatically scanning the code and powering on, and the plug-in power supply is automatically controlled. It can respectively switch on and off the 110V and 220V power supplies. Even if the wrong power supply is plugged in, it will not cause damage to the wine cabinet.
Temperature probe: optional thermocouple probe or imported DS18B20 temperature sensor chip, the plug adopts aviation anti-drop plug, the communication line is reliable, temperature resistance: -50℃～110℃, waterproof, pressure resistance, and folding resistance. Each sensor line is marked with a different color code to indicate its purpose to prevent misplacement.
Barcode scanner: It can be equipped with a wireless handheld scanner or automatic scanner to realize product barcode data collection.
Wireless communication module: industrial grade, full duplex communication mode,
Optional wireless mode: communication frequency: 433M, communication radius: ≥100m, to ensure smooth communication and high reliability.
Optional wifi communication method: each box is equipped with a set of wireless wifi module, which transmits the data to the communication base station (set in the center of the ring line), and finally to the computer for processing.
Optional number of wireless base stations: redundant configuration, convenient for signal coverage and automatic switching.
Computer communication card: industrial-grade communication card or communication server, with photoelectric isolation.
Soft control system:
1. The system can adapt to the combination of product dynamics and statics, long-term running test, coordinate various functional hardware to achieve automatic test of characteristic parameters (temperature, current, voltage, power), meet high-efficiency (beat: 15s/unit) production, and the net detection time can be Functions such as adjustment (20 to 300 minutes, users can set independently according to specific conditions), automatic judgment, automatic establishment of original model standards, product information collection and other functions.
2. The soft control system has the functions of automatic bar code entry and detection of station address information. The cabinet model and the test plan are automatically corresponded, so that different cabinets (models, batches) can be tested according to different test plans (test time, sampling frequency, power supply voltage control, judgment standards, etc.).
3. The soft control system has the functions of automatic leak detection and error correction of cabinet information. The barcode scanner at the entry box reads the data, the I/O module and the sensor at the exit read the outgoing record of the collection box sequentially. If there are gaps or omissions, if the data is abnormal, it will automatically determine whether the box has returned and whether it is dynamic Sampling inspection stations, the overall information is guaranteed to be complete.
4. Option to connect the test data with the MES system, send the scan code information and test data to the MES system or the line PLC control system in real time, and control the product flow out.
