Detailed Description

EPA (Ethernet for Plant Automation) is used as an open real-time Ethernet standard applicable to industrial field equipment, can well apply IT technology to an industrial control system, and establishes a standard for real-time work applicable to the field equipment by utilizing a deterministic communication scheduling strategy of efficient, stable and standard Ethernet and UDP/IP protocols. EPA can be constructed on the most general Ethernet, and wireless protocols such as GPRS, zigbee, bluetooth, CDMA1X and the like can be seamlessly accessed into an EPA industrialized network platform.

The utility model provides a communication device based on EPA agreement can realize better security performance, makes things convenient for dismouting and maintenance, is favorable to realizing remote communication. A communication apparatus according to an embodiment of the present invention is described below with reference to fig. 1 and 2.

Fig. 1 shows a perspective view of a communication device 1 according to an embodiment of the present invention. Fig. 2 shows a further perspective view of the communication device 1 according to an embodiment of the invention. Fig. 1 is a view from a front angle and fig. 2 is a view from a rear angle.

As shown in fig. 1, the communication apparatus 1 may include: printed Circuit Board (PCB) is provided with a plurality of connectors on printed circuit board, the protection level of a plurality of connectors satisfies IP67 standard, can realize that the protection dust inhales (wholly prevents the contact, and protection dust infiltration), and the protection is short-lived to be soaked (prevents soaking). In the embodiment shown in fig. 1, the plurality of connectors may include: a power connector 11, an input/output (I/O) connector 12, a bus connector 13 based on the EPA protocol.

Since the protection level of the EPA protocol product in the past is IP20, the EPA protocol product can only be applied to the environment in a cabinet; however, the protection level of the communication device according to the present invention can reach IP67, and can be applied to a more severe field environment, for example, dust inhalation protection (prevention of dust contact, penetration of dust protection), and short soaking protection (prevention of soaking) can be realized.

The communication apparatus 1 further includes: the flexible package 10 is embedded with the printed circuit board provided with the connector.

Furthermore, the communication device 1 may further include a housing for enclosing the flexible package 10.

The power connector 11 may be an M12L snap five-core connector. For example, two power connectors 11 may be symmetrically provided, that is, the number of the power connectors 11 may be 2.

The I/O connector 12 may be an M12A snap four-core connector. For example, eight I/O connectors 12 may be symmetrically arranged, i.e., the number of I/O connectors 12 may be 8. The printed circuit board may be utilized to convert the I/O signals to digital signals based on the EPA protocol.

The EPA protocol based bus connector 13 may be an M12D buckle quad connector. For example, two EPA protocol based bus connectors 13 may be symmetrically arranged, i.e., the number of EPA protocol based bus connectors is 2.

The connectors are small in size and all reach the protection level IP67. In addition, the use of a specific type of connector is advantageous for extending the communication distance, for example, long distance (e.g., 90 meters) telecommunications can be realized based on M12L-five-core connectors, M12A-four-core connectors, and M12D-four-core connectors, which can meet the voltage requirements and anti-interference shielding requirements of communications in combination with the adapted cable.
