Description

Technical Field

[0001] The utility model relates to a separate controller for a heat preservation lamp in a breeding farm, belonging to the technical field of temperature control. Background Art

[0002] In modern pig farms, in order to meet the needs of the newborn piglets for a warm environment in the farrowing bed, the ambient temperature in the farrowing house needs to be controlled. The normal ambient temperature for the growth of newborn piglets is about 35 degrees. To ensure the normal growth of piglets, when the temperature is low in winter, heat lamps are usually used to locally heat the piglet activity area to provide a suitable ambient temperature for the growth of piglets.

[0003] At present, the temperature control of the piglet growth environment is realized by using heat lamps, which is mainly achieved by controlling the output power of the heat lamps. There are two control methods:

[0004] The first is that the heat lamp is equipped with different temperature gears, and the output power is controlled by manually switching the gear switch. Not only the output power of the heat lamp cannot be adjusted automatically, but also this method of manually switching the gear cannot achieve the real-time maintenance of the ambient temperature within the temperature range suitable for the growth of piglets;

[0005] The second is that a separate controller is installed in the heat lamp, which automatically adjusts the output power. When the ambient temperature is lower than the set value, it runs at full power. When the ambient temperature reaches the set value, the output power is directly reduced proportionally. After the temperature drops, it runs at full power again. This control method causes the temperature of the heat lamp to change frequently, which will cause the piglet growth environment to be hot and cold. Moreover, in the existing design, the separate controller is integrated with the heat lamp. When a fault occurs, it can only be replaced as a whole, resulting in a high cost of use. In addition, the current heat lamp controllers do not have a communication function, and cannot enable the background server to monitor the temperature of the piglet growth environment in real time.

[0064] When the separate controller described in the utility model is used for the heat preservation lamp in the breeding farm:

[0065] It is only necessary to electrically connect the separate controller 1 to the mains power supply 2 and the heat preservation lamp 3 through wires (see Fig.11 As shown); therefore, the separate controller described in the utility model can realize convenient transformation of the heat preservation lamp without temperature control function in the existing farms. Not only is the transformation cost low, but also when the heat preservation lamp fails and needs maintenance, only the heat preservation lamp needs to be replaced, and the maintenance cost is low and convenient.

[0066] The transformer unit in the separate controller 1 of the utility model can convert the commercial power supply 2 into the DC power supply required by the separate controller 1 .

[0067] The temperature detection unit in the separate controller 1 described in the utility model can detect the real-time temperature of the environment in which the heat preservation lamp 3 is located (in this embodiment, the separate controller 1 is installed in the farrowing house of the farm, and detects the real-time environmental temperature in the farrowing house), and can transmit the detected real-time temperature to the MCU therein; and the MCU is preset with a target temperature, and the real-time temperature and the target temperature can be displayed in real time through the digital tube display unit.
