具体实施方式detailed description
本发明提供了一种基于ZigBee和嵌入式系统的养殖环境监控系统，养殖场环境智能监控系统由采集端、服务器端和客户端三部分构成。所述采集端负责采集养殖场的温度、湿度、光照等参数，通过ZigBee模块将采集数据发送到服务器端。采集端的个数和监控范围大小根据养殖场的规模及环境来决定。服务器端是整个系统的核心，接收采集终端发送的温湿度、光照强度信息，并向客户端提供所需要显示的环境信息数据，更要分析和判断环境信息是否异常，并把客户端发送的控制命令转发到采集端从而实现对异常环境的调控。养殖户在客户端对采集到的环境信息进行远程查看，对采集端相关设备进行远程控制，从而远程调控养殖场的温度、湿度、光照强度。The invention provides a breeding environment monitoring system based on ZigBee and an embedded system. The intelligent monitoring system of the breeding farm environment consists of three parts: a collection end, a server end and a client end. The collection end is responsible for collecting parameters such as temperature, humidity, and light of the farm, and sends the collection data to the server end through the ZigBee module. The number of collection terminals and the size of the monitoring range are determined according to the scale and environment of the farm. The server side is the core of the whole system. It receives the temperature, humidity and light intensity information sent by the collection terminal, and provides the client with the environmental information data that needs to be displayed. It also needs to analyze and judge whether the environmental information is abnormal, and control the information sent by the client. The command is forwarded to the acquisition end to realize the regulation of the abnormal environment. Farmers remotely view the collected environmental information on the client terminal, and remotely control the relevant equipment at the collection end, thereby remotely adjusting the temperature, humidity, and light intensity of the farm.
请参阅图1，采集端包括单片机、温湿度传感器、光照传感器、风扇、摄像头、OLED显示屏，所述温湿度传感器用于采集养殖舍现场环境信息并发送给所述单片机，所述单片机接收所述信息通过所述OLED显示屏显示，并分别控制所述光照传感器、风扇和摄像头工作，电源模块用于为系统供电，所述单片机通过所述ZigBee模块与所述服务器端连接，将采集的信息发送至所述服务器端。Please refer to Fig. 1, the acquisition end includes single-chip microcomputer, temperature and humidity sensor, light sensor, fan, camera, OLED display screen, and described temperature and humidity sensor is used for collecting the on-site environment information of breeding house and sends to described single-chip microcomputer, and described single-chip microcomputer receives all The above information is displayed through the OLED display screen, and controls the light sensor, the fan and the camera to work respectively. The power supply module is used to supply power to the system. sent to the server.
所述单片机还连接有报警装置用于发出声光报警。The single-chip microcomputer is also connected with an alarm device for sending out sound and light alarms.
采用OV9650摄像头拍摄各养殖舍现场画面，视频传至服务器端的视频模块进行处理，实现对整个养殖场的视频监控。The OV9650 camera is used to capture the on-site pictures of each breeding house, and the video is transmitted to the video module on the server side for processing, so as to realize the video monitoring of the entire farm.
养殖场内的温度与湿度属于正常温湿度范围，所以在温湿度传感器选型时不用考虑耐高温和低温的特殊要求。由于要根据采集到的养殖场温湿度对养殖场温湿条件进行调控，所以对传感器的采样精度要求较高，传感器的响应时间则要求要小。温度误差应该控制在1℃内，湿度误差应该控制在3％RH内，传感器的响应时间应该小于15s。使用DHT11数字温湿度传感器，该传感器各项指标都符合要求，而且成本比较低。The temperature and humidity in the farm belong to the normal temperature and humidity range, so there is no need to consider the special requirements of high temperature and low temperature resistance when selecting the temperature and humidity sensor. Since the temperature and humidity conditions of the farm should be regulated according to the collected temperature and humidity of the farm, the sampling accuracy of the sensor is required to be high, and the response time of the sensor is required to be small. The temperature error should be controlled within 1°C, the humidity error should be controlled within 3%RH, and the response time of the sensor should be less than 15s. Using DHT11 digital temperature and humidity sensor, all indicators of the sensor meet the requirements, and the cost is relatively low.
养殖场里的光照不会太强，所以对量程的要求不高，一般传感器都可以满足量程要求。由于要实时控制，对精度的要求比较高。采用ISL29003光照传感器，具有体积小、稳定性高、响应时间短、抗干扰能力强、防水能力强的优点。The light in the farm is not too strong, so the requirements for the range are not high, and the general sensors can meet the range requirements. Due to the need for real-time control, the requirements for precision are relatively high. Using ISL29003 light sensor, it has the advantages of small size, high stability, short response time, strong anti-interference ability and strong waterproof ability.
ISL29003是一种集成光传感器，内置ADC和标准IIC接口，可采集周围光照强度，并把采集到的模拟量转化为数字量，最后通过IIC输出。该传感器可采集和显示1～64000勒克斯的光照强度。ISL29003 is an integrated light sensor with built-in ADC and standard IIC interface, which can collect the ambient light intensity, convert the collected analog quantity into digital quantity, and finally output through IIC. The sensor can collect and display light intensity from 1 to 64000 lux.
服务器端包括64位微处理器，存储器、视频模块和电源电路，所述64位微处理器通过所述ZigBee模块与所述采集端连接，所述存储器用于将所述64位微处理器接收的数据进行存储，所述视频模块用于对接收的视频数据进行处理，所述电源电路用于为所述服务器端供电。The server end comprises a 64-bit microprocessor, a memory, a video module and a power supply circuit, the 64-bit microprocessor is connected with the acquisition end through the ZigBee module, and the memory is used to receive the 64-bit microprocessor The video data is stored, the video module is used to process the received video data, and the power supply circuit is used to supply power to the server.
所述64位微处理器通过GPRS模块和/或WIFI模块与所述客户端无线连接。The 64-bit microprocessor is wirelessly connected with the client through a GPRS module and/or a WIFI module.
系统选用ZigBee作为采集端和服务器端的无线连接方案，ZigBee模块使用ZICM2410模块，ZICM2410是集成CPU的单片ZigBee芯片，为采集端和服务器端的ZigBee网络提供高性能，低成本的射频收发方案。The system selects ZigBee as the wireless connection solution between the acquisition end and the server end. The ZigBee module uses the ZICM2410 module. ZICM2410 is a single-chip ZigBee chip integrated with a CPU.
本发明监控系统的工作过程如下：The working process of the monitoring system of the present invention is as follows:
采集端对养殖场温度、湿度、光照强度信息每秒采集一次，并对采集到的数据进行判断，如果采集到的数据格式正确，把采集到的数据经过处理打包发送给服务器端，由服务器端产生相应的命令发回给采集端。为了方便查看采集端的运行状态，每个养殖舍配有OLED显示屏对采集到的环境信息进行现场实时显示。考虑到服务器端与采集端的交互安全性问题，正常情况下采集端由服务器端全部控制。当由于意外导致服务器端无法正常控制采集端进行环境异常报警时，采集端30s之后自动切换到自控模式，在自控模式下采集端进行自我环境异常检测。The acquisition end collects the temperature, humidity, and light intensity information of the farm once per second, and judges the collected data. If the collected data format is correct, the collected data is processed and packaged and sent to the server. Generate corresponding commands and send them back to the acquisition end. In order to facilitate the viewing of the running status of the collection terminal, each breeding house is equipped with an OLED display to display the collected environmental information in real time. Considering the interaction security between the server and the acquisition end, under normal circumstances the acquisition end is fully controlled by the server end. When the server cannot normally control the collection terminal to issue an environmental abnormality alarm due to an accident, the collection terminal will automatically switch to the self-control mode after 30 seconds, and the collection terminal will perform self-environmental abnormality detection in the self-control mode.
单片机采用基于ARM Cortex-M0架构的LPC11C14，主要面向高集成度和低功耗的嵌入式应用，64位微处理器采用S5PC100，具有低成本、低功耗、高性能的优点，适用于对性能要求高、处理数据量比较大的嵌入式系统。The single-chip microcomputer adopts LPC11C14 based on ARM Cortex-M0 architecture, which is mainly for embedded applications with high integration and low power consumption.
