Abstract

The invention relates to an intelligent constant-temperature constant-liquid-level dairy cow drinking trough control system which is composed of a water inlet module, a water outlet module, a temperature control module, a liquid level control module and a WIFI module, the temperature control module is connected with a water temperature sensor and an environment temperature sensor through lines, and the liquid level control module is connected with a liquid level sensor through a line; numerical values detected by the water temperature sensor and the environment temperature sensor are processed through a linear fitting algorithm, so that the accuracy and precision of the detection values are improved; the numerical value detected by the liquid level sensor is processed through a median filtering algorithm, so that the accuracy and precision of the detected value are improved, and the system can accurately measure the liquid level height under the condition that the liquid level fluctuates. The cow drinking water waiting time and the cleaning sewage discharging time are greatly shortened, the heating efficiency is improved, and sewage is reduced; the water temperature is increased uniformly; automatic cleaning ensures that dairy cow drinking water is as clean as possible; the intelligent control realizes centralized control, one-key adjustment and combined linkage of the water tank.

Description

technical field [0001] The invention relates to the technical field of animal husbandry and breeding machinery, in particular to an intelligent constant temperature and constant liquid level cow drinking trough control system. Background technique [0002] We all know that 87% of milk is water. Dairy cows need to consume 3-5 kg ​​of water for every 1 kg of fresh milk they produce. Therefore, it is very important to ensure sufficient drinking water for dairy cows in the process of large-scale pasture production. [0003] At this stage, centralized water supply equipment has been widely used in various large-scale pastures, but there are still many problems, mainly in the following five aspects: [0004] 1. Slow speed of water up and down: The unreasonable design of the water up and down system of the tank leads to slow water up and down: the slow speed of water up makes the cows have to wait for drinking water, especially the cows that have just returned to the barn from th...

Problems solved by technology

[0004] 1. Slow speed of water up and down: The unreasonable design of the up and down water system of the tank leads to slow water up and down speed: the slow speed of water up makes the cows have to wait for drinking water, especially the cows that have just returned to the barn from the milking parlor. The secretion of milk consumes a lot of water in the body, and it is separated from the water source for a long time, so it needs to be replenished at the first time. The slow speed of water supply in the tank prolongs the drinking time of the previous cows, and the subsequent cows have to wait in line, resulting in untimely drinking water. Lower milk production in the next stage

The slow water speed reduces the cleaning efficiency of the sink. For some sinks equipped with manual drain plugs, the cleaners can complete the entire cleaning operation after the dirty water is completely drained from the sink and the upper and lower drain plugs are covered. Therefore, the number of sink cleaning per unit time is reduced.

[0005] 2. Inaccurate parameter control: Inaccurate control of parameters such as the liquid level and water temperature of the tank

Excessive water capacity not only reduces the heating efficiency of the tank, but also increases the amount of sewage generated by back-end cleaning

Inaccurate water temperature control leads to too high or too low heating temperature, reducing the willingness of cows to drink water

[0006] 3. High heating energy consumption: the existing water tank heating devices mostly use a number of strip heating plates attached to the bottom of the tank body, the heating speed is slow, the heating block is not heated uniformly, and the heating energy consumption is high

[0007] 4. Unable to realize automatic cleaning: the existing water tanks are still mostly cleaned manually, the cleaning efficiency is low, and the cows are stressed during the cleaning process

[0008] 5. Low degree of intelligence: Most of the existing water tanks are controlled by a single machine, and the parameters of the water tank need to be adjusted separately for different regions and usage environments, which cannot achieve network control and the degree of automation is low

[0009] 6. The liquid level measurement data is inaccurate: the water level fluctuates greatly when the cows drink water, and the existing water tanks mostly use float valves to control the liquid level, which has a high failure rate and inaccurate liquid level measurement, resulting in the inability to provide a constant and sufficient water source for the cows in time;

[0010] 7. Inaccurate temperature measurement data: Most of the existing water tank temperature measurements only measure the temperature of a single point in the tank. The data source is single and the measurement data has not been processed. There is a gap with the real temperature, and the ambient temperature is not evenly considered, resulting in accurate temperature measurement. The temperature and accuracy are low, which will affect the control of the water temperature by the heating device; in addition, if the ambient temperature is too low, it will also cause the failure of the electromagnetic valve heating plate and other mechanisms in the water tank, which will affect the drinking water tank to provide enough drinking water at an appropriate temperature for the cows in time;
