[0019] Figure 1 , 2As shown, the casing 8, the pressure sensor D1, and the water flow generator FD are located below the waterline. The data transmission circuit includes a GPRS module D4 and a data acquisition module D2. The power input ends 1 and 2 of the data acquisition module D2 and the GPRS module D4 are connected via wires respectively, and the signal output end of the data acquisition module D2 is connected to the signal input end of the GPRS module D4 via wires. In the water quality detection circuit, one end of the first resistor R is connected to the collector of the phototransistor Q1, the emitter of the phototransistor Q1 is connected to one end of the second resistor R2, and the other end of the first resistor R is connected to the positive electrode of the infrared light emitting diode VL.

The control circuit is a single-chip microcomputer module D3 with multiple power output ends, and can also use one of PLC or time-controlled switches. The two poles of the solar panel G1 and the two poles of the battery G2, the 1st and 2nd feet of the GPRS module D4 of the power input end of the data transmission circuit, one end of the resistor R of the power input end of the water quality detection circuit and the negative pole of the infrared light-emitting diode VL, the other end of the resistor R4 of the power input end of the water flow detection circuit, the 1st and 2nd feet of the pressure sensor D1 of the power input end of the water pressure detection circuit, and the 1st and 2nd feet of the single-chip microcomputer module D3 of the power input end of the control circuit are connected through wires.

[0020] Figure 1 , 2As shown, the new model mainly uses the depth of color of wastewater as a detection of whether to discharge sewage (if other data in the water is required, the corresponding probe can be installed and the data can be transmitted wirelessly. The detection and transmission of other data in the water are not protected by this new model). The relevant functional departments of this new model (such as the environmental protection department) install the equipment at the sewage outlet of the relevant production area. Usually, the solar panel G1 generates electricity under the light to charge the battery G2. In this way, the new model does not need to set up power supply lines, and the installation and use are more convenient, and the energy saving purpose is achieved accordingly. After the control circuit is powered, pins 3, 4 and 5, 6 of the single-chip computer module will cyclically output positive and negative and negative and positive and negative polarity power at certain intervals (for example, power is output for 10 seconds every hour) to enter the power input terminal of the electric linear slide M1. After the positive and negative poles of the electric linear slide M1 are powered, its sliding block will drive the casing of the water quality detection circuit, the water flow generator of the water flow detection circuit, the pressure sensor of the water pressure detection circuit, etc. to move from left to right. After the positive and negative poles of the electric linear slide M1 are powered, its sliding block will drive the casing of the water quality detection circuit, the water flow generator of the water flow detection circuit, the pressure sensor of the water pressure detection circuit, etc. to move from right to left. Pins 7, 8 and 9, 10 of the single-chip microcomputer module will cyclically output positive and negative and negative-positive power supplies at certain intervals (for example, outputting power for 8 seconds every 1 hour) to enter the power input terminal of the electric push rod M2. After the positive and negative poles of the electric push rod M2 are energized, its push column will drive the casing of the water quality detection circuit, the water flow generator of the water flow detection circuit, and the pressure sensor of the water pressure detection circuit from top to bottom. After the negative and positive poles of the electric push rod M2 are energized, its push column will drive the casing of the water quality detection circuit, the water flow generator of the water flow detection circuit, and the pressure sensor of the water pressure detection circuit from bottom to top. Through the above, the new model can control the water quality detection circuit, the water flow detection circuit, and the water pressure detection circuit to realize uninterrupted collection of water quality, water flow and water pressure data of different water levels and different areas at the sewage outlet of the production area (the collected data is more comprehensive, and the water discharged from the wastewater outlet may have different pollution levels in different water layers and different locations).

[0021] Figure 1 , 2As shown, after the water pressure detection circuit is powered on, when the water level in the corresponding area is high (or the pressure sensor D1 is located at a greater depth in the water), the pressure detected by the pressure detection surface of the pressure sensor D1 is relatively large, and the voltage signal output by its 3rd pin is relatively high. When the water level in the corresponding area is low (or the pressure sensor D1 is located at a lower depth in the water), the pressure detected by the pressure detection surface of the pressure sensor D1 is relatively small, and the voltage signal output by its 3rd pin is relatively low. The dynamically changing voltage signal enters the 3rd pin of the data acquisition module D2 through the current limiting and voltage reduction of the resistor R1. In the water flow detection circuit, when the flow rate of the wastewater discharged on site is relatively large (the impeller of the water flow generator FD is aligned with the water inflow direction), the voltage signal output by the water flow generator FD is relatively large. When the flow rate of the wastewater discharged on site is relatively small, the voltage signal output by the water flow generator FD is relatively small. The voltage signal output by the water flow generator FD (5V small DC water flow generator) varies with the water flow and is divided by the resistors R3 and R4 to enter the 3rd pin of the data acquisition module D2. In the water quality detection circuit, the 12V power supply is stepped down by the resistor R to supply power to the infrared light emitting diode VL. The infrared light emitting diode VL emits light and irradiates the light receiving surface of the phototransistor Q1. The phototransistor Q1 is turned on and the emitter output voltage signal is limited and stepped down by the resistor R2 to enter the 4th pin of the data acquisition module D2. In actual situations, when the quality of the discharged wastewater is relatively good, its transparency is relatively large, and the degree of blocking the light emitted by the infrared light emitting diode VL is relatively low. The light received by the light receiving surface of the phototransistor Q1 is relatively large, and the signal voltage entering the 4th pin of the data acquisition module D2 is relatively large. When the quality of the discharged wastewater is relatively bad, its transparency is relatively low, and the degree of blocking the light emitted by the infrared light emitting diode VL is relatively high. The light received by the light receiving surface of the phototransistor Q1 is relatively low, and the signal voltage entering the 4th pin of the data acquisition module D2 is relatively small. After the dynamically changing water flow rate, water pressure, and water transparency voltage signals enter the multi-channel signal input end of the data acquisition module D2, the data acquisition module D2 converts the dynamically input multi-channel analog voltage signals into digital signals and outputs them to the signal input end of the GPRS module D4. The GPRS module D4 transmits the dynamically changing signals remotely through the wireless mobile network, and the remote relevant personnel can understand various on-site data in real time through a PC or smart phone (the production management personnel can also understand the water flow conditions of the on-site sewage outlet based on the received data, such as knowing that the wastewater discharge flow rate has decreased, the water pressure has become relatively low, etc., which means that the amount of wastewater discharged by the production equipment has decreased, and there may be problems with the cooling water supply, so they can go to the site in time for processing, etc.), which provides strong technical support for reducing pollution and formulating relevant measures (for example, if the environmental protection department learns that the transparency of the on-site wastewater has deteriorated and the degree of pollution is high, it can go to the site in time for disposal and urge the production department to make rectifications).It should be noted that the data acquisition module collects multiple analog voltage signals and converts the multiple signals into digital signals for wireless transmission, and the remote PC or smart phone related applications receive the data and display it in digital or waveform form through the display screen. This is an extremely mature IoT data transceiver and display technology. This application only uses mature IoT data transceiver and display technology to realize the collection, conversion, transmission and display of water level, water pressure and water pollution degree data in the wastewater discharge area (the higher the digital signal or waveform representing the water level, water pressure and water pollution degree observed by the remote relevant personnel on the screen, the higher the water level, water pressure and water pollution degree on the site, and vice versa, the lower the water level, water pressure and water pollution degree on the site). This new model does not provide any technical protection for the data acquisition module to collect multiple analog voltage signals and convert them into digital signals for wireless transmission via the GPRS module, and the remote PC or smart phone related applications receive the data and display it in digital or waveform form through the display screen. Figure 2 Among them, the battery G2 model is 12V / 10Ah; the electric push rod M2 is a reciprocating electric telescopic rod finished product with a power of 10W; the electric linear slide M1 is a 50W electric screw slide finished product; the resistance values ​​of resistors R1, R, R2, R3, and R4 are 4.7K, 1.8K, 4.7K, 47K, and 5K respectively; the infrared light-emitting diode VL model is BT401; the phototransistor Q1 model is 3DU4; the data acquisition module is an analog voltage signal acquisition module of model DAM3152, which has multiple analog voltage signal acquisition terminals, and can convert multiple analog voltage signals collected into digital signals and output them through one RS485 data port; the GPRS module D4 is The finished GPRS module model LTE-658 has two power input terminals and one RS485 data input port; the pressure sensor D1 is a finished diffused silicon pressure transmitter model YD322, which has two power input terminals and one signal output terminal. When working, the signal output terminal will output a dynamically changing 0-5V voltage signal according to the detected pressure; the main control chip of the single-chip microcomputer module D3 is STM32F042K6U6 (the single-chip microcomputer module works through the internal circuit, and the power output at different times of 3, 4, 5, 6, 7, 8, 9, and 10 is an extremely mature technology. This application does not provide any protection for this technical point); the solar panel G1 model is 12V / 1Ah.
