PH value monitoring wireless sensing network (WSN) node device for preventing secrete drainage of sewage and monitoring method

Abstract

The invention discloses a PH value monitoring wireless sensing network (WSN) node device for preventing secrete drainage of sewage and a monitoring method. The PH value monitoring WSN node device comprises a floating ball floating in water in a sealed manner and a square shell which is fixedly connected with the bottom of the floating ball and is immersed in the water, wherein an antenna bracket table and a communication antenna are fixedly arranged in an upper half ball cover; a charging interface and a power switch are arranged on the antenna bracket table; a circuit board is fixed at the bottom in a lower half ball cover; a water storehouse is arranged at the bottom in the square shell; a water feeding storehouse is arranged on one side of the upper part of the water storehouse; a magnet valve is arranged between the water feeding storehouse and the water storehouse; the lower end of a PH value sensor extends into and is suspended in the water feeding storehouse; an electromagnet bracket fixed on the inner wall of the square shell is arranged on the upper part in the square shell; an electromagnet is supported on the electromagnet bracket; the upper end of a spring is fixedly connected with the electromagnet bracket, and the lower end of the spring is connected with the magnet valve just under the electromagnet; and when the PH value of a target water domain reaches an abnormal alarm threshold value, the valve can automatically open and collect samples with low water quality.

Description

technical field [0001] The invention relates to a wireless sensor network monitoring technology, in particular to a WSN (wireless sensor network) node device used for monitoring the PH value of sewage to prevent illegal discharge. Background technique [0002] At present, in order to reduce investment costs, some sewage discharge enterprises do not strictly follow the national discharge standards for effective treatment and discharge of the industrial sewage generated, but choose to quietly discharge sewage that does not meet the standards in the middle of the night or early morning. The time of the discharge may be intermittent, or the discharge duration is not very long, so that the management personnel who monitor the water quality cannot monitor it in time. Therefore, the supervisory personnel can only conduct spot checks and patrols at night accordingly, but this will not only cost a lot of money A lot of manpower and material resources are often missed, and its work ef...

Problems solved by technology

[0004] The purpose of the present invention is to provide a WSN node device and monitoring device for monitoring the PH value of the anti-sewage illegal discharge in view of the irregular and instantaneous discharge of sewage by the existing sewage illegal discharge enterprises, which leads to the phenomenon that supervisors cannot monitor in a targeted manner. The method can carry out random real-time monitoring of the target water area of ​​the sewage outlet of the enterprise, so that the supervisory personnel can obtain real-time problematic water quality samples without being on-site, and can easily take them back for further detailed testing of the water samples to improve monitoring. Efficiency, effectively prevent sewage from sneaking
