Ship-borne weather instrument sensor interface circuit and method for merging and identifying connected sensor

Abstract

The invention discloses a ship-borne weather instrument sensor interface circuit with a simple structure and capable of avoiding misoperation and improving the safety operation of equipment and a method for merging and identifying a connected sensor. According to the technical scheme, the ship-borne weather instrument sensor interface circuit comprises a host interface (1) and a sensor interface (2) and is characterized in that the sensor interface (2) adopts a connector with 7 pin cores, and pins are defined as P1: 5V, P2: 12V, P3: 24V, P4: GND, P5: 485A, P6: 485B, and P7: T, namely connected for detecting. The invention further discloses a method for identifying a connected sensor.

Description

technical field [0001] The invention belongs to the field of a single-circuit structure of a ship weather instrument sensor interface, in particular to a ship weather instrument sensor interface circuit and a method for mixed-insertion identification and access sensors with simple structure, capable of avoiding mis-insertion operations and improving equipment safety operation. Background technique [0002] Ship meteorological instruments require the measurement of various elements, and need to be connected to a large number of sensing devices, such as wind sensors, temperature and humidity sensors, air pressure sensors, water temperature, visibility, salinity, gyrocompass, wave meter, GPS, and a total of 10 types of log meters , Each device requires a connector, plus AC and DC power access, satellite communication access, VDR output, splitter output, etc., there are a large number of connectors.

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
