Problems solved by technology

[0004] However, many water quality monitoring devices are placed in water areas that need to be tested. The flow of water and factors considered by the outside world may cause the water quality monitoring device to be moved or stolen. Then we need to regularly monitor the water quality monitoring device and judge the quality of the water quality monitoring device. whether it was stolen

Embodiment 1

[0029] Embodiment 1, the multi-parameter water quality telemetry system 1 reads the real-time latitude and longitude information (x, y) of the GPS module 4, and the latitude and longitude information (x) read during installation 0 ,y 0 ) for comparison, the formula for calculating the real-time position information of the multi-parameter water quality monitor is as follows:

[0030]

[0031] Where R is a set constant.

[0032] When F(x,y)

[0033] ΔT Under normal conditions, in order to reduce the traffic consumption in data transmission, the reading interval between STM32F103 MCU 3 and GPS module 4 is 10 minutes, and we set it to be 10 minutes to submit monitoring data once. During the communication process between MCU 3 and GPS module 4, use The technology of heartbeat packet keeps the status of device transplantation and mobile network networking.

Embodiment 2

[0034] Embodiment 2, the multi-parameter water quality telemetry system 1 reads the real-time latitude and longitude information (x, y) of the GPS module 4, and the latitude and longitude information (x) read when installed 0 ,y 0 ) for comparison, the formula for calculating the real-time position information of the multi-parameter water quality monitor is as follows:

[0035]

[0036] Where R is a set constant.

[0037] When F(x, y)>=r, it is determined that the device is stolen or lost by water. Send the location parameters to the server at the first time, then set the ΔT submitted by the data communication in the communication to 1min, so as to facilitate accurate tracking of the geographical location of the device.

[0038] STM32F103 MCU 3 adopts the modbus communication protocol to read the water quality parameter data of the address unit of the online multi-parameter water quality monitor, and at the same time control the start and stop of the online multi-paramete...

Abstract

The invention discloses an anti-theft system for a water quality monitoring device. The system comprises a multi-parameter water quality remote monitoring system, the multi-parameter water quality remote monitoring system is provided with a communication main unit, an STM32F103 single chip, a GPS module, an NB-IOT antenna, a solar charging panel, an NB-IOT antenna and a cloud control server, the STM32F103 single chip is used as a management core on the multi-parameter water quality remote monitoring system, data of water quality parameters of an address unit of an online multi-parameter waterquality detector is read, and meanwhile starting and stopping of the online multi-parameter water quality detector are controlled; the STM32F103 single chip collects information of the longitude and latitude of the online multi-parameter water quality detector through the GPS module for comparison with a set threshold value, and when a difference value is larger than the threshold value, it is judged that a mounting box is flushed away or stolen. According to the system, by adopting a B / S architecture and a WEB development technology, dual-direction communication of a water quality monitoringterminal is achieved, a manager or an operator can monitor the system just by opening a webpage on a browser of a computer or a mobile phone or a tablet computer, client side software does not need tobe installed, and operation and control are more conveniently conducted.

Description

technical field [0001] The invention relates to the field of anti-theft technology for water quality monitoring devices, in particular to an anti-theft system for water quality monitoring devices. Background technique [0002] Water quality monitoring is the process of monitoring and measuring the types of pollutants in the water body, the concentration and change trend of various pollutants, and evaluating the water quality status. The scope of monitoring is very wide, including unpolluted and polluted natural water (river, river, lake, sea and groundwater) and various industrial drainage. The main monitoring items can be divided into two categories: one is comprehensive indicators reflecting water quality, such as temperature, chromaticity, turbidity, pH value, conductivity, suspended solids, dissolved oxygen, chemical oxygen demand and biochemical oxygen demand etc.; the other category is some toxic substances, such as phenol, cyanide, arsenic, lead, chromium, cadmium, m...
