Embodiment 1

[0041] This embodiment provides a sewage treatment method, which is applied to two parts: a sewage treatment station and a monitoring center.

[0042] see figure 1 The shown flow chart of the sewage treatment method applied to the sewage treatment station, the method includes the following steps:

[0043] Collection step S110: Collecting data from the sewage treatment equipment through the PLC module to obtain equipment operation data.

[0044]The PLC module in the sewage treatment station takes PLC (Programmable Logic Controller) as the core, and completes the operation and debugging of various sewage treatment equipment through the input of various sensors and related analog inputs in the sewage treatment station. These PLC modules are connected to the sewage treatment equipment through hard wiring or RS485 network communication.

[0045] After the operating data of the sewage treatment equipment is obtained through the PLC module, the wireless communication component in s...

Embodiment 2

[0058] This embodiment provides a sewage treatment system, see image 3 As shown, it includes a sewage treatment station 300 and a monitoring center 400 .

[0059] The sewage treatment station 300 includes:

[0060] The PLC module 310 is used to collect data from the sewage treatment equipment to obtain operating data of the sewage treatment equipment. Data transmission between the PLC module and the sewage treatment equipment is carried out through hard wiring or RS485 network communication.

[0061] The wireless communication component 320 is used to transmit the equipment operation data to the monitoring center; it is also used to receive the control instructions returned by the monitoring center.

[0062] The wireless communication component is a wireless GPRS module, including an alarm sub-module, which is used to monitor the communication status of the wireless GPRS module in real time, and send an alarm reminder message and a remote control message when a communicatio...

Abstract

The invention provides a sewage treatment communication method and system, relating to the technical field of automatic control. The method comprises following steps: a collection step: carrying out data collection on sewage treatment equipment by virtue of a PLC module, so as to obtain equipment operation data; a transmission step: transmitting the equipment operation data to a monitoring centerby virtue of a wireless communication assembly; and a control step: receiving a control instruction returned by the monitoring center by virtue of a wireless communication assembly, and controlling the sewage treatment equipment according to the control instruction. By replacing a traditional wired communication manner with the wireless communication assembly, the problems that the construction iscomplex, the cost is relatively high, and the examination is inconvenient in the current wired communication manner are solved; and power is supplied to a PLC station by virtue of a solar power generation device under an abnormal power-off condition, so that the problems that the continuous power supply time of a traditional continuous power supply is short, and the cost of a high-capacity continuous power supply is high are solved.

Description

technical field [0001] The invention relates to the technical field of automatic control, in particular to a communication method and system for sewage treatment. Background technique [0002] With the continuous expansion of the city and the rapid growth of population data, the scale of urban sewage is also increasing, and the water quality is becoming more complex. Effective treatment of urban sewage is required. [0003] Urban sewage treatment refers to the measures taken to change the nature of sewage so that it will not cause harm to environmental waters. In the process of urban sewage treatment, various facilities, equipment and technology should be used to separate the pollutants contained in the sewage from the water, so that harmful substances can be converted into harmless substances, thereby purifying the water quality and making full use of water resources. The process of urban sewage treatment involves a large number of mechanical equipment such as valves, wate...
