The present invention discloses one kind of automatic boiler cold state test system and method. Several wind speed measuring probes are fixed via fixtures in measurement positions of the burner exit to measure accurate wind pressure signals, which are averaged in multi-channel pipeline, converted into electric signal in the pressure difference converter, converted in A/D converter into digital quantity and processed in microprocessor; the processed data are sent via pressure difference radio transceiver to main controlling radio transceiver and fed to computer via the communication interface for further processing to obtain the measurement results. The present invention has the advantages of simple installation, accurate data, fast measurement, etc. 本发明公开了一种锅炉冷态试验自动测试系统及其试验方法。它是通过固定装置将多只风速测量探头固定在燃烧器出口的测量位置处，测得准确的风压信号，通过连接管路将多点信号经多通接头平均后由差压变速器将压力信号转换成电信号，再经A/D转换器转换成数字量后送入微处理器处理，处理后的数据经差压无线收发器以无线通讯方式发送给主控无线收发器并通过通讯接口输入计算机进行处理，得出测量结果。本发明具有安装简便，数据准确、测量速度快、非人工测量等优点。
