集鱼灯实地光照数据量大，现有测试设备因船体摇摆和潮位变动等因素造成较大的数据误差。为降低测试过程中数据误差较大的问题，设计了一种新型测试系统，使用CC2530单片机为照度测试的下位机，采用GY-30模块为光强检测元件，以Zigbee作为主控器与终端设备之间的无线通讯方式。系统实施过程为：当光子投射到GY-30模块时，会产生对应大小的电流，电流经电路放大后被终端CC2530采集，该模块将数据发送至网络中的协调器，协调器通过USB与PC上位机连接并传输测试数据。结果显示，以单次测试样本7×6数据量为例，按照传统测试方法耗时约为120 min，而使用新系统可缩短至20 min，在数据准确度方面也有大幅提高。利用新系统测试大面积的光场分布，在一定程度上能减少误差，同时可减少灯光测试的重复性操作。

The data quantity involved in luminance field test using fish-attracting lamps is usually very large and with existing devices, luminance data may vary much due to ship swaying, wave surge and tide. In order to reduce data errors in the measurement, a wireless luminance measurement system was designed. The system uses CC2530 microcontroller as the lower control system, GY-30 module to detect the light intensity, and Zigbee module as the communication apparatus between the master control device and terminal control units. When the GY-30 module is projected with light, it will produce electric current of corresponding magnitude to that of the light. The electric current data will be collected by terminal CC2530 modules and sent to the network coordinator, which is linked to the master computer by USB and thus could further transmit the data. The results showed that, with the single test sample of 7×6 in size, the measuring time using traditional method was about 120 min, while with the new system, the time could be shortened to 20 min, and the accuracy of data was also improved significantly. Therefore, using the new system to measure the light field distribution of large area could reduce, to some extent, the errors and repetitive operations during the luminance measurement.
