Problems solved by technology

[0003] During equipment installation, especially maintenance, it is necessary to perform plug-in and plug-in operations of sensor connectors. In the case of less demand for connectors, different core numbers of connectors can be used to prevent misoperation, but in the case of more connectors Under the circumstances, the scheme with different number of cores is no longer feasible
Especially in the equipment compartment of the ship cabin, due to the narrow space, the equipment identification on the connector is not easy to check. If the number of cores is the same, it is easy to cause mis-insertion operation. If the pin definition is not careful in the early design, it is likely to appear Circumstances of damaged equipment

Embodiment Construction

[0018] figure 1 Among them, a sensor interface circuit for a ship weather instrument, including a host terminal interface 1 and a sensor terminal interface 2, the sensor terminal interface 2 adopts a connector with 7 pin cores, and each pin is defined as P1: 5V, P2: 12V, P3: 24V, P4: GND, P5: 485A, P6: 485B, P7: T is access detection. Host-side interface 1 and sensor-side interface 2 are connected through photoelectric coupling.

[0019] exist figure 1 The left side of the middle is the host side of the device, and the right side is the sensor side. Through this definition, our host can be connected to different sensors of 5V, 12V, and 24V. Other types of interfaces are similar, but the signal pin interface is different and the number of cores is different.

[0020] The method for identifying the access sensor by mixed insertion of the sensor interface circuit of the ship weather instrument comprises the following steps:

[0021] (1) Classify all access devices, and then d...
