771-A 16-channel 24-bit 256kHZ vibration signal collector

771-A 16-channel 24-bit 256kHZ vibration signal collector

1. Product overview
Data collector is an intelligent terminal running Linux operating system. With the support of Ethernet network, a large-scale distributed intelligent data collection system can be quickly built. The collector terminal is small, low power consumption, easy to integrate, can be added waterproof shell, reaching the IP67 protection level. Using the Visual Studio integrated development environment, with a large number of open source and third-party resources, users can complete the development of collector programs in a very short time, such as continuous signal acquisition, data processing algorithm, network communication, etc., with high development efficiency and low difficulty. The collector uploads the calculation results to the server, and the amount of data is reduced compared with the original collected data, which occupies lower network resources, reduces the hardware configuration requirements of the server, and greatly reduces the hardware cost of the server. Network communication transmission reliability, good platform adaptability, simple development and operation, and rich development resources. Users can back up data locally, and ensure the integrity of data in case of network failure or server power failure. Applicable to: thermal power, wind power, chemical industry, shipping, aviation
