Abstract
Description
Technical Field
[0001] This utility model relates to a livestock and poultry environmental monitoring system, specifically to an intelligent monitoring system for the deodorization effect of livestock and poultry houses with deodorization effect monitoring and network reporting functions. Background Technology
[0002] With the continuous expansion of livestock production and the increasing intensification of operations, the production of large quantities of livestock and poultry products also generates significant amounts of malodorous substances, such as hydrogen sulfide, ammonia, volatile fatty acids, trimethylamine, methane, skatole, and thiols, which mix together to produce an unpleasant odor. This seriously harms the health of livestock and poultry, and also endangers the health of humans, especially livestock farmers. Furthermore, the release of these substances into the atmosphere can potentially form acid rain, polluting the environment. Therefore, effectively controlling the malodorous emissions from livestock farms is an urgent problem that needs to be solved to ensure the sustainable development of the livestock industry.
[0003] 1. Traditional GC-MS technology is only used for chemical composition analysis and cannot monitor gas concentration. Moreover, the equipment cost exceeds 150,000 yuan and the analysis time is long, which cannot meet the real-time early warning needs of farms.
[0004] 2. Commercial electronic nose sensors have a relatively large monthly drift rate and significant detection errors in high-humidity environments such as livestock and poultry houses;
[0005] 3. The existing monitoring system lacks a synchronous sampling mechanism before and after deodorization, only performs single-point monitoring, and has a single sensor layout. It does not set up comparison sampling points at the inlet and outlet of the deodorization equipment, making it impossible to accurately assess the deodorization effect and efficiency.
[0006] 4. Data reporting relies on manual entry, and the efficiency of connecting with the relevant environmental protection department's platform is low, while manual reporting is time-consuming;
[0007] 5. The system lacks an automatic assessment function for environmental indicators after the deodorization equipment is in operation, requiring manual comparison of data to determine whether standards are met, which is inefficient and prone to errors. Utility Model Content

[0012] The data processing module is connected to the APP client and the environmental monitoring department's server via the communication module.
[0013] The carbon dioxide sensor, ammonia sensor, hydrogen sulfide sensor, and temperature and humidity sensor are distinguished by their respective device address codes.
[0014] The data processing module uses an industrial control computer.
[0015] It also includes a power supply circuit for powering the monitoring system; the power supply circuit includes a power source and a 220V to 12V transformer connected to the power source via a leakage current protector; the output of the 220V to 12V transformer is connected to a parallel line and a step-down module respectively; the power source powers the industrial control computer, and the step-down module is connected to a relay.

[0024] The data processing module has a built-in GB18596-2001 emission standard database, which automatically compares the collected parameters before and after deodorization with the threshold.
[0025] The data processing module is connected to the computer, the APP, and the environmental monitoring department's server via the communication module.
[0026] The carbon dioxide sensor, ammonia sensor, hydrogen sulfide sensor, and temperature and humidity sensor are distinguished by their respective device address codes.

[0029] The gas monitoring equipment box has a waterproof shell, which is suitable for the humid environment of livestock and poultry houses;
[0030] This utility model features a three-layer hardware architecture, wherein:
[0031] Sampling Layer: The air inlet of the monitoring equipment box is connected to the air inlet of the deodorizing equipment via an air inlet pipe, and the air outlet is connected to the air outlet of the deodorizing equipment via an air outlet pipe. The air inlet pipe is equipped with an air inlet solenoid valve, and the air outlet pipe is equipped with an air outlet solenoid valve. The air inlet solenoid valve and the air outlet solenoid valve are respectively connected to the data processing module via relays. Sensor groups (temperature, humidity, ammonia, hydrogen sulfide, carbon dioxide) are arranged in the monitoring equipment box. Different sensors are distinguished by device address codes. For temperature sensors, they correspond to device 1 and device 6 to distinguish between before and after deodorization. They are led out from the equipment box and placed in the corresponding positions. The gas sensors are controlled by relays to control the solenoid valves to open and close different channels at timed intervals to distinguish the detected gas before and after deodorization. The sampling flow rate is 200-300 mL / min.
[0032] Communication layer: RS485 bus (9600 baud rate) transmits data, Modbus RTU protocol CRC16 check rule: crc=(crc&1)?(crc>>1)^0xA001:crc>>1;
[0033] Control layer: The relay module (LH-08.js control) links the deodorization equipment according to the data processing results, and the industrial control computer controls the start and stop.
