  2. 2. The monitoring system for monitoring the safety of sows and newborn piglets of claim 1, further comprising an infrared detection module, wherein the infrared detection module is used for measuring body temperature information of the sows and the piglets and performing thermal imaging on the data processing module.
  3. 3. The monitoring system for monitoring the safety of sows and newborn piglets according to claim 2, wherein the data processing module is pre-stored with a thermal imaging temperature map, the temperature interval in the thermal imaging picture is displayed by comparing the thermal imaging of the piglets and the sows with the temperature map, and if the body temperature of the piglets or the body temperature of the sows exceeds a threshold value, the data processing module sends a possible fever investigation instruction to a breeder.
  4. 4. The system for monitoring the safety of sows and newborn piglets of claim 1, further comprising an environmental monitoring module for monitoring environmental data of the pigsty, wherein the environmental data comprises at least temperature and humidity.
  5. 5. The system for monitoring the safety of sows and newborn piglets according to claim 4, further comprising an air conditioner compressor, wherein the air conditioner compressor is used for adjusting the room temperature in the pigsty, when the temperature monitored by the environment monitoring module is lower than or higher than a threshold range, the data processing module sends out a heating or cooling instruction, the air conditioner compressor starts to adjust the temperature in the pigsty to the threshold range after receiving the instruction, and if the humidity does not reach a humidity threshold standard, water is sprayed through the water sprayer to adjust the humidity to the humidity threshold.

Description

Monitoring system and monitoring method for monitoring safety of sow and newborn piglet Technical Field The invention relates to the field of livestock health monitoring, in particular to a monitoring system and a monitoring method for monitoring the safety of sows and newborn piglets. Background In pork production, sows play a role in breeding piglets, so that the breeding and health conditions of the sows are highly valued by managers. In the breeding process, the sow can repeatedly get up and lie at a specific time point before delivery, and the sow is prone to being pressed by the sow due to frequent rising and lying after delivery. Most sows are fed by adopting limiting fences. The sow breeding process mainly comprises several stages of oestrus hybridization, pregnancy, farrowing and postpartum lactation, and the later production activities mainly occur in a delivery room. The improper delivery management and delivery of the sow can easily cause a series of problems, such as prolonged sow labor, low temperature and inappetence after delivery, no milk syndrome, postpartum infection and the like, and the problems of the sow often cause the increase of morbidity and mortality of piglets, and influence the survival rate of the piglets. The key measures of sow delivery and postpartum care are mainly to perform farrowing monitoring and postpartum care while the environmental control (such as temperature, humidity, air quality and noise) of a delivery house is well controlled. The invention patent with the application number 201910777209.1 relates to a sow health monitoring method and a sow health monitoring system, which can record the complete activity state of each sow from the feeding to the discharging, find that abnormality can be traced in the whole course, give birth to prompt and early warning, reduce the risk of the piglets being pressed up and the like, automatically warn and prompt the working staff to check the sow delivery process at reduced manpower time, enable the original work to be more timely and efficient, effectively reduce the contact between personnel and foreign objects and the sow, reduce the risk of epidemic situation infection, and greatly avoid stress response caused by personnel contact. According to the technology, the characteristics of the behaviors of the sow are analyzed through the picture information of the camera, so that the safety monitoring of the sow and the piglets is finished, the newborn piglets need to be placed at the side of the sow, and as the newborn piglets need to eat the colostrum early, the technology does not have innate immunity and the immunity is obtained by eating the colostrum. Allowing piglets to eat the colostrum as early as possible is the only effective way for primary piglets to obtain antibodies against various infectious diseases. If colostrum is not eaten, it is difficult to keep alive. The colostrum contains various nutrients and bioactive substances required by piglets besides enough immune antibodies. The piglet can eat the colostrum at any time after birth, can stimulate the activities of digestive organs, promote the discharge of the embryo and stool, increase nutrition and heat production, and improve the resistance of the piglet to cold. If the images are extracted only through the camera, the actual situation of the piglets cannot be displayed, for example, the piglets are too much to be shielded, or the sow completely presses the piglets to form the full coverage situation, so that the situation of the piglets which are not in the images cannot be known through the image information. Disclosure of Invention The invention provides a monitoring system and a monitoring method for monitoring the safety of sows and newborn piglets, which can solve the problem that the sows extruded piglets cannot be identified due to picture shielding. The monitoring system for monitoring the safety of the sows and the newborn piglets comprises a camera, a data processing module and a sound pick-up, wherein the camera is used for capturing image information of the newborn piglets and the sows, the data processing module is used for acquiring the image information, extracting and tracking outlines of the sows and the piglets in the image information in real time, if the outline information of the piglets is located at positions which cannot be seen by the waist of the sows and below the sows and the outline and tracking information of the piglets are interrupted when the standing and lying states of the sows change, judging that the piglets are pressed and giving out alarm information, the sound pick-up is arranged in a sow rest area and used for acquiring environmental sound information of the whole body of the sows, the data processing module is used for analyzing the environmental sound information, judging that the piglets are in unexpected situations when the low-frequency hissing sound occurs, and the water spray device is used for spraying hot water
