A collection, recording and transmission device for on-site detection data of environmental protection monitoring

Technical field:

The utility model relates to the technical field of environmental protection detection devices, in particular to a collection, recording and transmission device for on-site detection data of environmental protection monitoring that can monitor the environmental protection pollution treatment status of enterprises in real time or at regular intervals.

Background technique:

With the development of the economy, the quality of the environment is showing a trend of deteriorating, one of the important reasons is the lack of supervision and the backwardness of the monitoring means. In the past, similar products could not detect comprehensive data such as the actual current change of the pollution treatment motor, the amount of pollutant discharge, the PH value, and the COD value in real time. Therefore, the monitoring was not strict, and it was easy for some companies to exploit loopholes and secretly discharge pollutants. For example, a detection generating device with a patent number of 00237903.1 obtains a signal current from a current sensor corresponding to the power motor of a sewage treatment device, and converts it into a digital signal current through an analog conversion circuit, and converts the motor current into a digital signal current after processing by a microprocessor. The value is shown on the display. Although the device can finally achieve online continuous measurement, its application range is limited because it is only for power motor monitoring, the monitoring object is single and the monitoring range is too narrow. In the case of variable and diverse random sewage discharge and non-standard sewage discharge, or the sewage discharge caused by artificial illegal operations of enterprises driven by other interests, the device also appears to be powerless.

Invention content:

The purpose of this utility model is to overcome the defects of the prior art, to provide a real-time or regular online remote monitoring of environmental pollution treatment status of enterprises, and at the same time, it can meet the collection and recording of on-site detection data of environmental protection monitoring with variability and diversification. with transmission device.

The utility model is realized through the following technical scheme: the device is additionally equipped with input ports that can be connected to measuring instruments such as PH meter, COD, turbidity meter and flow meter, wherein the input port of the flow meter is directly connected with the microprocessor, and at the same time The output end of the processor is connected with the wireless transceiver module.

The device can also be provided with a calendar clock circuit connected to the microprocessor, and the output port of the microprocessor is also connected to a memory, a liquid crystal display module and an upper computer device.

The input terminal of the utility model can be connected to various types of environmental protection measuring instruments to realize diversified monitoring, and adopts the wireless cellular network mode, which saves the cumbersome wiring of similar devices in the past; at the same time, the real-time measurement data on site is collected, compressed, After packaging, it can be stored in the large-capacity data memory in the machine, and can also be sent to the environmental monitoring center wirelessly in real time according to the set time interval; it has strong real-time performance, fast speed, high data accuracy, and wide implementation range.
