On-off time of an infrared emitting diode of the plurality of the reflection-type infrared optoelectronic switches in the electromagnetic flowmeter can be timely adjusted according to different working states such as working time and non-working time, and a problem that the electromagnetic flowmeter is always in a conducting state and consumption is big is avoided. In addition, only one I / O port of the single chip microcomputer is needed for receiving end portions of the plurality of the reflection-type infrared optoelectronic switches for time sharing judgment, and possibility is provided for extension of other functions of the single chip microcomputer.

The embodiment of the invention provides a method and device for determining a repeated message, applied to the first network device in a redundant loop network. The first network device comprises a first port and a second port, wherein the first port and the second port are used for receiving the messages sent by the second network device. The method for determining a repeated message comprises the following steps: counting the number of the messages received by the first port when the first port receives the first message; judging whether the number of the messages received by the first port is less than or equal to the number of the messages received by the second port or not; determining the first message to be a repeated message if the number of the messages received by the first port is less than or equal to the number of the messages received by the second port. By means of the embodiment of the invention, the speed of determining repeated messages is improved.
