Description

Technical Field

[0001] The utility model relates to poultry breeding environment control equipment, belonging to the technical field of poultry breeding. Background Art

[0002] With the development of modern science and technology, the three-dimensional cage technology of poultry in animal husbandry has been widely popularized. Poultry cage farming has many advantages, such as high stocking density, convenient management of all aspects, improved feed conversion rate, and conducive to disease prevention and control.

[0003] At present, most of the sheds for large-scale breeding adopt closed environment, poor air circulation, dust in feed, large number of poultry, large breathing volume, large exhaust gas, and poultry flapping their wings during activities, which drive dust in feed and feces emitted by poultry's own fallen feathers. The air quality is too poor and poultry is prone to respiratory diseases. Therefore, in the production environment, electrical equipment is used to turn on fans and windows to remove dust and circulate air. After turning on the fan, the temperature of the shed will drop as fresh air from the outside enters, which will cause stress to the poultry, so precise control of the fan is crucial.

[0004] In addition, since poultry is raised in multi-layer cages, it is necessary to keep the temperature of the shed at a constant temperature as much as possible. In addition, due to the high breeding density and compact cages, natural light cannot enter the shed, so there is a problem of weak light in the shed. Poultry needs 24-hour lighting during the brooding stage to facilitate poultry to find water, feed and resting places more easily, so that poultry can get used to the dark environment and achieve low-carbon environmental protection. The lighting time for breeding also gradually decreases with the increase of age. After one week, the lighting is turned on only when the poultry needs to be fed and watered, and some time periods are during the day and some are at night. Manually turning on and off lights and adjusting light brightness increases the difficulty of breeding. It is necessary to develop an integrated poultry breeding environment control device.

The terms used herein in the specification of the present invention are only for the purpose of describing specific embodiments and are not intended to limit the present invention.

[0029] See also Figure 1, the embodiment of the utility model provides a poultry breeding environment control device, including a main controller 1, a temperature and humidity sensor 2, a carbon dioxide sensor 3, a relay control board 4, a drinking water sensor 5, a feeding sensor 6 and a switch power supply 7;

[0030] Among them, the temperature and humidity sensor 2 is connected to the main controller 1 through an ADC pin, and the temperature and humidity sensor 2 is used to monitor the temperature and humidity in the poultry breeding shed; the carbon dioxide sensor 3 is connected to the main controller 1 through an ADC pin, and the carbon dioxide sensor 3 is used to monitor the carbon dioxide concentration in the poultry breeding shed;

[0031] Among them, the relay control board 4 and the main controller 1 are connected via the RS485 interface using the ModbusRTU protocol, the relay control board 4 is electrically connected to the fan or wet curtain pump in the poultry breeding shed through the AC contactor, and the relay control board 4 is used to start and stop the fan, wet curtain pump or heater in the poultry breeding shed;

[0032] Among them, the drinking water sensor 5 and the main controller 1 are connected via the RS485 interface using the ModbusRTU protocol, and the drinking water sensor 5 is used to monitor the water supply of the water inlet pipe in the poultry breeding shed;

[0033] Among them, the feeding sensor 6 and the main controller 1 are connected via the RS485 interface using the ModbusRTU protocol, and the feeding sensor 6 is used to monitor the feed supply of the feed tower in the poultry breeding shed;

[0034] Among them, the switching power supply 7 and the main controller 1 are connected through an ADC interface, and the switching power supply 7 is also connected to the lighting lamp in the poultry breeding shed. The main controller 1 is used to adjust the output voltage value of the switching power supply 7 through the ADC interface to adjust the brightness of the lighting lamp.

[0035] In this embodiment, a 24V relay 8 is also included. The 24V relay 8 is connected to the main controller 1 through an I / O pin. The 24V relay 8 is also connected to the ventilation window control motor in the poultry breeding shed through an AC contactor. The 24V relay 8 is used to start and stop the ventilation window control motor in the poultry breeding shed; a human-computer interaction screen 9 is also included. The human-computer interaction screen 9 and the main controller 1 are connected through an RS485 interface using the ModbusTCP protocol. The human-computer interaction screen 9 is used to receive user interaction instructions for the poultry breeding environment control device.

[0036] Specifically, the main controller 1 is used to control the fan and ventilation window control motor in the poultry breeding shed in linkage, wherein the fan can be controlled in different zones as needed. When the fan is not started, the ventilation window control motor controls the ventilation window to close as well. Before the fan is started, the ventilation window is opened to the set position in advance. After the ventilation window is opened to the specified position, the fan starts immediately. At the same time, the human-computer interaction screen 9 allows the user to freely set the breeding age and fan start time in the breeding stage, and adjust the number of fans and running time at the beginning of each fan level. After the user completes the setting, the ventilation window can start and stop with the fan in the ventilation state, which not only ensures the ventilation volume but also ensures that the shed is not affected by the external environment when the fan is stopped.

[0037] Among them, the main controller 1 uses the ADC interface to collect the analog signals (4-20MA) of the temperature and humidity sensor 2 and the carbon dioxide concentration sensor in the shed. When the environmental parameters in the shed are lower than or higher than the threshold set by the breeder, the command to turn on or off the fan is executed. At the same time, several fans are grouped and divided into 18-36 fan groups. The number of fans in each group is different, the start time is different, and the start conditions are different. Through large-scale breeding technology, refer to the breeding environment in each region and the breeding experience of breeding technicians, and adjust the fan operation level on the human-computer interaction screen 9. Achieve the best ventilation state in a shed, and set a minimum ventilation at the same time. Start when the outdoor temperature is low in winter, and only maintain a ventilation function.

[0038] Among them, the I / O interface of the main controller 1 is used to output the switch signal, and the relay is used to control the disconnection and connection of the main contact of the AC contactor, so as to achieve the function of controlling the start and stop of the fan. The fan cooperates with the negative pressure ventilation mode in the level mode operation state. The negative pressure ventilation mode is to adjust the opening ratio of the ventilation window through the micro-pressure difference sensor (analog signal 4-20MA) when the micro-pressure difference sensor detects the pressure difference inside and outside the shed. When the main controller 1 is in the automatic operation state, the ventilation window is opened to the relevant position in advance with the start of the fan. When the GPIO interface of the fan relay is set to 0, the GPIO interface of the ventilation window is also set to 0, so that the ventilation window and the fan are synchronously accompanied.

[0039] In this embodiment, the main controller 1 establishes a connection with the enterprise cloud platform server 10 through the Ethernet interface using the Ethernet MQTT protocol, and the enterprise cloud platform server 10 is used to store the data collected by the poultry breeding environment control device. In addition, the poultry breeding environment control device can be remotely controlled through the enterprise cloud platform server 10 to record the environmental data in the shed at all times, so that users can make decisions that are in line with breeding technology: the number and time of turning on the fan, etc.
