Abstract:
1. An electronic card module (an electronic module or an electronic board) equipped with a function of storing fabrication information, maintenance information, and operation information about a product and configured to have various electronic parts mounted on a PCB and to have a main function circuit unit configured therein, thus implementing a specific system, the electronic card module, comprising: an information provision unit integrally formed with the PCB forming the electronic card module and configured to store the fabrication information, maintenance information, and operation information of the electronic card module and to provide the pieces of information when there is a request from an external device, the information provision unit comprising: a communication port for communicating with the external device in accordance with a serial communication multi-drop method; an information storage memory for storing the fabrication information, maintenance information, and operation information of the electronic card module; an operating time detection circuit for detecting information about an operation of the main function circuit unit; a control unit for performing control so that temperature, humidity, and voltage are detected and an operating time is detected and performing control so that the pieces of information about the electronic card module is stored in the information storage memory based on the pieces of detected information; a voltage detection unit configured to detect actual voltage supplied from the main function circuit unit to the electronic card module; a temperature/humidity sensor configured to detect temperature and humidity external to the electronic card module; and an A/D conversion circuit connected to have one side connected to the temperature/humidity sensor and the other side connected to the control unit and configured to ND convert an analog temperature/humidity signal for determining whether the electronic card module is stably operated into digital temperature/humidity data, wherein information about used temperature and humidity is obtained for each hour and stored in the information storage memory.
