Pig breeding monitoring system

Abstract

The invention discloses a monitoring system for pig rising, which consists of at least one raising monitoring station and a supervisory personal computer. The raising monitoring station consists of a weighing guardrail device, a weighing manger device, a feed proportioning device and an intelligent controller which is used for monitoring the weighing guardrail device, the weighing manger device and the feed proportioning device and the input/output interface of which is connected with an LCD touch screen, a signal conditioning device, which is used for conducting an amplification and an A/D conversion to at least two channels of load sensor signals, an RF transmitter for ID signals, which is used for identifying pigs and a drive circuit and used for controlling the feed electric motor arranged on the feed proportioning device. An RF ID card hung on the pig ear is additionally arranged to match with the RF transmitter for ID signals and the quantity of pigs needed to be monitored. The weighing guardrail device, the weighing manger device and the feed proportioning device all adopt simple and smart structures to coordinate with the computer control, thereby, the invention has simple structure, reliable performance, low manufacturing and using cost, small system error, high accuracy, low waste of feedstuff and high degree of automation; moreover, the invention can replace an imported product and satisfy the requirements for a modernized pig-raising production.

Description

technical field [0001] The invention relates to pig feeding equipment, in particular to a feeding monitoring system capable of real-time monitoring of the feeding physiological characteristics of pigs, especially breeding pigs. Background technique [0002] Pig trial breeding refers to the experimental breeding of pigs, including the trial breeding of breeding pigs, through scientific methods to find out the growth and reproduction laws of pigs, evaluate the feeding effect, and find scientific, economical and practical methods of raising pigs. According to modern genetic breeding theory, in order to select good breeding pigs, it is necessary to accurately measure various growth characteristic parameters of breeding pigs, including eating time, eating length, feeding amount, daily weight, weight gain, feed-to-weight ratio, etc. [0003] At present, the methods of domestic pig trial breeding are still relatively primitive: mainly relying on manual labor, which is labor-intensi...

AI Technical Summary

Problems solved by technology

[0007] 1. During the use of the system, there are often zero number event records (more than 300 per day at the beginning of use), and each time there is a very small amount of food intake, but the total number is large, which will affect the accuracy of the measurement results sex

[0008] 2. The measuring scale cannot automatically return to zero. The empty weight of the measuring scale often changes, and the range of fluctuation is 0.3-0.8kg, and some are even higher, which will also affect the accuracy of the measurement results.

[0009] 3. The system sometimes has a record of negative feed intake, and the amount is relatively large, resulting in negative feed intake for some pigs a day, which affects the accuracy of the measurement results

[0010] 4. The system wastes a lot of feed, and the more pigs there are, the greater the proportion, which affects the accuracy of the measurement results

[0011] 5. When the system transmits data, sometimes it cannot be completed at one time, and it needs to be repeated 1-2 times to complete, which affects work efficiency

[0012] 6. The reliability of the system is not good enough, and there are frequent failures in the early stage of use, resulting in the loss of data at the faulty station

[0013] 7. The shaft of the system installed on the batcher and the motor are meshed through gears, and the feed often falls into it, which causes system failure and cannot work stably

[0014] Chinese patent CN00941783Y also disclosed a new type of pig growth performance automatic measuring machine in September 2007. This machine is complex in structure, unreliable, and high in cost. There is no obvious improvement in the realization of functions compared with the above-mentioned American products.
