对于第一指示信号: 控制单元 103 直接输出第一指示信号到逻辑与单 元 105 , 逻辑与单元 105对第一指示信号进行逻辑与处理后, 将得到的电信 号输出给驱动器 106,驱动器 106在所述电信号的控制下驱动相应的指示灯 107发光,被驱动的指示灯 107将电信号转换为光信号输出, 呈现对应所述 第一指示信号的指示状态。
对于第二指示信号: 控制单元 103输出第二指示信号到编码 /调制单元 104进行组帧、 编码和调制后, 编码 /调制单元 104输出第二指示信号的调 制信号到逻辑与单元 105;逻辑与单元 105对第二指示信号的调制信号进行 逻辑与处理后,将得到的电信号输出给驱动器 106, 驱动器 106在所述电信 号的控制下驱动相应的指示灯 107发光, 被驱动的指示灯 107将电信号转 换为光信号输出, 呈现对应所述第二指示信号的指示状态。
其中,运行状态指示装置 101中可以包含两个或两个以上的指示灯 107、 具有两个或两个以上对应不同指示灯 107的接口的一个编码 /调制单元 104 或者两个或两个以上分别对应不同指示灯 107的编码 /调制单元 104, 具有 两个或两个以上对应不同指示灯 107的接口的一个逻辑与单元 105或者两 个或两个以上分别对应不同指示灯 107的逻辑与单元 105、以及具有两个或 两个以上对应不同指示灯 107的接口的一个驱动器 106或者包含两个或两 个以上的、 分别对应不同指示灯 107的驱动器 106。
实际应用中,如果运行状态指示装置 101中仅包含一个指示灯 107, 则 控制单元 103—次仅输出一个指示信号; 如果运行状态指示装置 101 中包 含两个或两个以上的指示灯 107,则控制单元 103—次可以输出用于驱动一 个指示灯 107 的一个指示信号, 也可以一次输出用于驱动多个不同指示灯 107的多个指示信号, 该指示信号可以是第一指示信号或第二指示信号。
对于第一指示信号: 控制单元 103直接输出第一指示信号到对应的逻 辑与单元 105或逻辑与单元 105上的对应接口, 逻辑与单元 105对第一指 示信号进行逻辑与处理后, 将得到的电信号输出给对应的驱动器 106或驱 动器 106上的对应接口, 驱动器 106在所述电信号的控制下驱动所述指示 灯编号所标识的指示灯 107发光, 该指示灯 107将电信号转换为光信号输 出, 呈现对应所述第一指示信号的指示状态。 对于第二指示信号: 控制单元 103输出第二指示信号到对应的编码 /调 制单元 104或编码 /调制单元 104上的对应接口, 编码 /调制单元 104进行组 帧、 编码和调制后, 输出所述第二指示信号的调制信号到对应的逻辑与单 元 105或逻辑与单元 105上的对应接口; 逻辑与单元 105对第二指示信号 的调制信号进行逻辑与处理后, 将得到的电信号输出给对应的驱动器 106 或驱动器 106上的对应接口, 驱动器 106在所述电信号的控制下驱动所述 第二指示信号中指示灯编号所标识的指示灯 107发光, 该指示灯 107将电 信号转换为光信号输出, 呈现对应所述第二指示信号的指示状态。
其中, 控制单元 103—次输出用于驱动多个不同指示灯 107的多个指 示信号时, 可以对两个或两个以上的指示灯 107进行编号, 并在控制单元 103配置各指示灯 107的指示灯编号,需要驱动某一个指示灯 107时可以在 相应的指示信号中添加其指示灯编号, 在控制单元 103 中配置各指示灯编 号与其输出通路之间的对应关系, 控制单元 103基于指示灯编号, 将指示 口, 或给对应的逻辑与单元 105或逻辑与单元 105上的对应接口。
或者, 还可以不添加指示灯编号, 直接在控制单元 103 中配置各指示 信号与其输出通路之间的对应关系, 控制单元 103依据此配置可以直接将 指示信号输出到对应的编码 /调制单元 104上或编码 /调制单元 104上的对应 接口, 或到对应的逻辑与单元 105或逻辑与单元 105上的对应接口。
需要特别说明的是, 第一指示信号和第二指示信号只是在功能上分为 两个信号, 在硬件传输上可以由一条通路进行传送。
这里, 每个指示灯 107可以有多种指示状态, 除了人眼能够识别的指 示状态(例如表示工作正常的全亮、 表示停止工作的全灭)夕卜, 指示灯 107 还可以有人眼不能识别的 N ( N为不小于 1的整数) 个指示状态 (例如不 同频率下的闪烁), 这 N个指示状态对应第二指示信号, 可以通过下述运行 状态检测装置 102进行检测后识別。
这里, 指示灯 107具体可以是 LED。
实际应用中, 第一指示信号可以是全亮的点灯电平或全灭的点灯电平, 第二指示信号可以是按照指定频率闪烁的点灯电平。 考虑到人眼的感知特 性, 所述指定频率一般要低于 50Hz,例如,如图 2所示,可以使指示灯 107 选用 1Hz频率(以 1秒为周期)进行闪灯,指示灯 107在半个周期( 0.5秒) 时间内加载第二指示信号的帧数据并闪烁, 另半个周期内全灭。
其中, 控制单元 103 可以是被测设备的控制单元, 可以采用单片机或 CPU 来实现, 也可以利用复杂可编程逻辑器件 ( CPLD, Complex Programmable Logic Device ) 或者现场可编程门阵列 (FPGA , Field - Programmable Gate Array )来实现。 编码 /调制单元 104、 逻辑与单元 105可 以通过与控制单元 103 连接, 实现上述信号处理, 也可以集成在控制单元 103中。
其中, 编码 /调制单元 104对输入的第二指示信号进行如下处理: 按照 预定义的帧结构对第二指示信号进行组帧, 然后, 将组帧得到的帧数据进 行双向间隔码(FM0, Bi-Phase Space )编码, 最后, 利用载波对编码后的 帧数据进行调制后得到第二指示信号的调制信号并输出。 这里, 对组帧得 到的帧数据进行 FM0编码的编码速率可以为 20Hz。 此处, 编码 /调制单元 104也可以使用其他的编码方式对帧数据进行编码, 不再列举。
这里, 对第二指示信号进行组帧为: 计算第二指示信号的帧长和循环 冗余校验(CRC, Cyclic redundancy check ) 16校验码, 并将所述第二指示 信号的帧头、 帧长度、 信息数据、 CRC16校验码一起组帧, 得到如图 3所 示的帧数据。 如果帧长度超过 0.5s, 可以将 N个第二指示信号分成多帧传 送, 如果小于 0.5s, 组帧时在 CRC 16校验数据后用数据 0填充。
这里, 预定义封装第二指示信号的帧结构, 如图 3所示, 分为 4个部 分: 第一字段(SEG1 )、 第二字段(SEG2 )、 第三字段(SEG3 )和第四字 段(SEG4 ), 其中, SEG1封装第二指示信号的帧头、 SEG2封装第二指示 信号的帧长度、 SEG3封装第二指示信号的信息数据、 SEG4封装第二指示 信号的 CRC16校验码。 这里, SEG3中可以封装一个或多个所述第二指示 信号的信息数据。 这里, 在第二指示信号中包含指示灯编号时, 所述第二 指示信号的信息数据中除可以包含第二指示信号本身的信息之外, 还可以 包含指示灯编号的信息。 实际应用中, 帧结构可以根据用户进行改变, 并 非是固定的。 相应的, 编码 /调制单元 104对第二指示信号进行组帧的过程 与所使用的帧结构相对应, 也并非固定的。
如图 4所示, 本发明的一种运行状态检测装置 102, 主要可以包括: 光 检测单元 108、 解调 /解码单元 109和显示单元 110。
其中, 光检测单元 108检测运行状态指示装置 101 的指示状态, 获取 运行状态指示装置 101 输出的光信号, 将该光信号转换为电信号, 再经放 大、 滤波和比较等处理后得到数字信号并输出到解调 /解码单元 109 , 解调 / 解码单元 109对所述数字信号进行解调和解码后, 得到第二指示信号并输 出给显示单元 110;显示单元 110根据所述指示信号显示相应的运行状态信 台
具体地, 图 5为光检测单元 108的内部框图, 光检测单元 108包括感 光元件 201、 放大模块 202、 滤波模块 203和比较模块 204。 感光元件 201 由光敏二极管或者光敏三极管电路组成。 光检测单元 108 的内部处理流程 为: 运行状态指示装置 101输出的光信号由感光元件 201检测并转换为电 信号, 该电信号再经过放大模块 202进行放大、 滤波模块 203进行滤波、 比较模块 204进行比较处理后转换为数字信号后输出。
具体地, 解调 /解码单元 109对所述数字信号做如下处理: 对输入的数 据信号先进行解调得到帧数据, 再检测所述帧数据的帧头, 如果能够识別 到帧头, 则根据所述帧数据 SEG2 中的帧长度截取帧数据的长度, 根据其 SEG4中的 CRC16校验码进行 CRC16校验, 如果 CRC16校验通过, 则输 出其 SEG3中的第二指示信号的信息数据给显示单元 110;如果不能够识别 到帧头或者 CRC16校验失败, 则抛弃当前帧数据。
具体地, 显示单元 110根据所述指示信号显示相应的运行状态信息, 处理过程如下: 在显示单元 110 中预先配置各第二指示信号的信息数据与 运行状态信息的对应关系列表, 显示单元 110根据第二指示信号的信息数 据, 从所述对应关系列表中查找到对应的运行状态信息, 并将该运行状态 信息显示出来。
