Description

数字式大气压力温度湿度测量记录仪Digital Atmospheric Pressure Temperature Humidity Measuring Recorder

技术领域 technical field

本发明属于测量技术领域,具体涉及一种大气环境参数测量仪器,尤其涉及一种大气压力温度湿度测量记录仪。 The invention belongs to the technical field of measurement, and in particular relates to an atmospheric environment parameter measuring instrument, in particular to an atmospheric pressure, temperature, and humidity measurement recorder.

背景技术 Background technique

目前大气环境参数测量仪多集中两种参数的获取,如温湿度计、压力温度计及压力湿度计。数据的显示及输出方式过于简单。数据与相关设备的交互极少,不便于数据的后续处理及利用。仪器的供电方式过于简单,供电范围比较窄。测量精度低是普遍存在的现象,对于高精度要求的场景不适用。很多仪器的传感器工作环境与待测环境存在差异,采样方法不合理。一般仪器的测量精度低、数据利用率低、输出方式单一及供电范围窄等,使得无法满足气象、科研、环保、军事、体育、医药卫生等领域的特定要求。 At present, most atmospheric environment parameter measuring instruments focus on the acquisition of two parameters, such as temperature-hygrometer, pressure thermometer and pressure-hygrometer. Data display and output methods are too simple. There is very little interaction between data and related equipment, which is not convenient for subsequent processing and utilization of data. The power supply method of the instrument is too simple, and the power supply range is relatively narrow. Low measurement accuracy is a common phenomenon, which is not applicable to scenarios requiring high precision. The sensor working environment of many instruments is different from the environment to be tested, and the sampling method is unreasonable. The low measurement accuracy, low data utilization rate, single output mode and narrow power supply range of general instruments make it impossible to meet the specific requirements of meteorology, scientific research, environmental protection, military, sports, medical and health fields.

具体实施方式 detailed description

数字式大气压力温度湿度测量记录仪供电通过接插件Power作为电源输入,其供电范围。 The digital atmospheric pressure, temperature and humidity measurement recorder is powered by the connector Power as the power input, and its power supply range.

为5-24V,首先输入电源经过大小电容CIN1、CIN2和CIN3进行高低频滤波,从而得到高品质供电电源,然后经过DC/DC模块输出稳定+5V电源,三端电源芯片ASM1117使得+5V变换成+3.3V供电给传感器模块、控制处理器模块、通信模块及启动模块工作,LED和限流电阻R9显示系统的供电是否正常,DC/DC模块与三端电源模块都集成有过流保护,从而系统保护合理可靠。接插件CONMS用于压力传感器连接控制处理器PA2-PA5的IO端口,PA2输出SCLK提供串行数据时钟信号;PA3与DIN连接提供串行数据输入功能;PA4与DOUT连接作为串行数据输出端口;PA5与MCLK连接提供给传感器工作时钟频率,在本设计中压力传感器工作频率为32.768KHz。接插件CONSHT用于温度湿度传感器连接控制处理器PA6-PA7的IO端口,PA6与SCK连接提供传感器工作频率及数据传输频率,在本设计中温度湿度传感器工作频率为100KHz;PA7与DATA连接作为温度湿度数据传输。系统上电工作后,控制处理器产生相应的驱动信号,传感器在驱动信号的驱动下,开始采样环境参数并将获取的数据按相应格式与速率传输到控制处理器相应缓存里,控制处理器接下缓存所获数据,解码后的数据按压力温度湿度顺序格式编码,然后通过RS232直接传输发送,无需交互指令。数据端口可以直接连接LED屏显示,同时也可通过上位机进行数据存储进行二次开发。 It is 5-24V. First, the input power is filtered by high and low frequency capacitors CIN1, CIN2 and CIN3 to obtain a high-quality power supply, and then the DC/DC module outputs a stable +5V power supply. The three-terminal power supply chip ASM1117 converts +5V into +3.3V supplies power to the sensor module, control processor module, communication module and start-up module. LED and current limiting resistor R9 show whether the power supply of the system is normal. Both the DC/DC module and the three-terminal power module are integrated with overcurrent protection, thus System protection is reasonable and reliable. The connector CONMS is used to connect the pressure sensor to the IO port of the control processor PA2-PA5. PA2 outputs SCLK to provide the serial data clock signal; PA3 is connected to DIN to provide the serial data input function; PA4 is connected to DOUT as the serial data output port; The connection between PA5 and MCLK provides the working clock frequency of the sensor. In this design, the working frequency of the pressure sensor is 32.768KHz. The connector CONSHT is used to connect the temperature and humidity sensor to the IO port of the control processor PA6-PA7. PA6 is connected to SCK to provide the sensor working frequency and data transmission frequency. In this design, the working frequency of the temperature and humidity sensor is 100KHz; PA7 is connected to DATA as the temperature Humidity data transmission. After the system is powered on, the control processor generates a corresponding driving signal. Driven by the driving signal, the sensor starts to sample environmental parameters and transmits the acquired data to the corresponding buffer of the control processor according to the corresponding format and rate. The obtained data is cached, and the decoded data is encoded in the order of pressure, temperature and humidity, and then transmitted directly through RS232 without interactive instructions. The data port can be directly connected to the LED screen for display, and it can also be used for data storage through the host computer for secondary development.
