The invention relates to a system for individually recording the production performance of layers and automatically monitoring the environment of a layer house, which comprises an intelligent coop, an environment monitoring system, an upper computer and a lower computer, wherein the intelligent coop and the environment monitoring system are respectively connected with the lower computer; the upper computer is connected with the lower computer through a field bus. The system is used for collecting data by using a plurality of Atmega16 cores as cluster controller nodes, and carrying out information communication by using a RS-485 form with central nodes to make the data transferred to a central monitoring computer at real time so as to realize real-time monitoring on the production performance and the environment parameters of the layer house, such as the weight of layers, the feed intake, the water drinking, the excretion quantity, the excretion times, the egg laying time, the egg weight, and on the like. The system accurately, stably and continuously records each parameter of breeding, feedstuff, nutrition, and the like for poultries, and has special realistic significance to workload reduction and automatic environment detection and control of a layer house.
