Embodiment Construction

[0018] The technical solutions of the present invention will be described in detail below in conjunction with the accompanying drawings.

[0019] An on-line ion concentration sensor with automatic maintenance, such as figure 1 As shown, it includes a measurement control unit, a measurement tank, an ion concentration probe, an intake pump, an exhaust pump, a measurement solution intake pump, a cleaning solution intake pump, a protection solution intake pump, and a buffer solution intake pump.

[0020] The measurement control unit is a single-chip microcomputer system, which uses Loongson 1C microprocessor chip as the central processing unit, uses 802.11a / b / g protocol remote wireless module as the communication module, and comes with a 12V lithium polymer battery as the power supply. The measurement control unit connects the ion concentration probe and the relay module through the RS485 bus, and uses the MODBUS protocol to control the relay module. The relay module is respectiv...

Abstract

The invention discloses an automatic-maintenance online ion concentration sensor which comprises a measuring control unit, a measuring tank, an ion concentration probe, a gas inlet pump, a gas exhaustpump, a measured solution inlet pump, a cleaning liquid inlet pump, a protection liquid inlet pump and a buffering liquid inlet pump. The measuring tank is a hollow container. Seven holes are formedin the top end of the measuring tank and include the ion concentration probe installation hole, the gas inlet hole, the gas exhaust hole, the measured solution inlet hole, the cleaning liquid inlet hole, the protection liquid inlet hole and the buffering liquid inlet hole, and a gas and water exhaust hole is formed in the bottommost end of the measuring tank. The measuring control unit is connected with and controls the work of the ion concentration probe, the gas inlet pump, the gas exhaust pump, the measured solution inlet pump, the cleaning liquid inlet pump, the protection liquid inlet pump and the buffering liquid inlet pump. The automatic-maintenance online ion concentration sensor has the advantages of being high in automation degree, low in labor cost, automatic in maintenance andfree of repairing and is suitable for online environment index detection, intelligent industrial production, intelligent agricultural and industrial ecological breeding and other application scenes ofunmanned sites.

Description

technical field [0001] The invention belongs to the technical field of sensors in the field of information technology, and in particular relates to an online ion concentration sensor with automatic maintenance. Background technique [0002] With the development of Internet of Things technology, various types of online sensors are used in various industries such as industrial production, environmental monitoring, and agricultural breeding. Among them, the online ion concentration sensor is of great significance for the measurement and control of total nitrogen, total phosphorus, pH value, dissolved oxygen and other indicators in soil and water because it can monitor the concentration of various ions in the solution in real time. [0003] However, the ion concentration probes of the existing on-line ion concentration sensors on the market all adopt a sensitive membrane transducer structure. In actual use, they must be cleaned frequently with ultrapure water and other cleaning ...
