| content prompt: hilin technology releases smart pump technology based on modbus communication protocol |
[modbus technology application scenarios]
hilin technology's micropump products are widely used in vocs volatile organic compounds monitoring, environmental online monitoring, smart granaries, smart city gas detection, cems flue gas monitoring and other fields. those pumps provide gas transportation for gas sampling, gas transmission, and vacuum applications. the pump needs to be controlled remotely, and cooperates with a variety of sensors such as pressure sensors, etc., to work according to the sensor feedback information under the scheduling of the central control device, and it is necessary to monitor and alarm the pump's operation in real time. by supporting the modbus communication protocol, it is easy to integrate hailin technology micropumps with various intelligent instruments and control systems at industrial control sites.
[modbus rtu protocol based on rs-485]
modbus was invented by modicon (now a brand of schneider electric) in 1979 and is the world's first bus protocol that is truly used in industrial sites. modbus rtu is a compact, serial communication method that uses binary to represent data, and relies on the rs485 serial port for communication at the physical layer.
[remote start and stop control function]
the modbus communication protocol developed by hilintec supports the control of the start and stop of the pump. the user can send the start and stop control signals through the host to control the start and stop of the pump, thereby realizing the on-off control of the medium transmission.
[speed control function]
the speed of the pump is controlled by modbus communication protocol. the user can send the speed control signal through the host to control the speed of the pump to achieve the flow control of the medium transmission.
[working condition monitoring function]
the modbus host can query the working status of the micropump in real time, such as whether it is started, working speed, running time, whether there are faults and historical faults, so that the central control system can understand the working status of the gas circuit and air source, power supply voltage fluctuations, load status, micropump working conditions such as remaining life.
[models supported by modbus technology]
at present, hilin technology's c50 series top-matching products, d50 series top-matching products, c60 series top-matching products can be customized to support modbus features. for more other models, please contact hilintec's pre-sales engineers for customization.
