Problems solved by technology

[0003] However, most of the lower computers in the existing equipment only set up a serial interface and connect to the upper computer through a serial interface. In this way, in some specific scenarios, the serial interface may not be enough, for example, there are 2 When the intelligent dynamic environment monitoring unit collects the monitoring data of a lower computer at the same time, it is obviously impossible to connect with two upper computers through a serial interface. At this time, the distribution and expansion of the serial interface is very important.

example 1

[0041] The controller obtains the monitoring control instruction of the first device within a preset time when the serial port distribution device is powered on.

[0042] When the serial port distribution device is used in the dynamic environment monitoring system, because the upper computer needs to obtain the monitoring data of the lower computer in real time, and monitor the lower computer, usually the serial port distribution device is always in working state since the factory is turned on. In the embodiment, the "preset time for the serial port distribution device to be powered on" may be the preset time after the serial port distribution device is powered on for the first time from the factory. Wherein, in the controller acquiring the monitoring control instruction of the first device, the first device may be all first devices connected to the first serial interface set on the serial port distribution device.

[0043] Wherein, when the first device sends a monitoring control ...

example 2

[0046] When the first DIP switch is triggered by the first trigger instruction, the controller clears the monitoring control of the first device corresponding to the first DIP switch acquired by the serial port distribution device within the preset time of power-on. Command, and obtain the current monitoring control command of the first device.

[0047] The first DIP switch can be triggered by the first trigger instruction within the preset time or after the preset time when the serial port distribution device is powered on. Among them, it is obtained when the controller clears the serial port distribution device within the preset time triggered by power-on In the monitoring control command of the first device corresponding to the first DIP switch, since each first DIP switch is correspondingly provided with a first serial interface, and because each first serial interface is connected with a first serial interface A device, therefore, the first device corresponding to the first ...

[0051] When the second DIP switch is triggered by the second trigger instruction, the controller obtains the monitoring control instruction of the first device through the external input of the second serial interface.

[0052] For example, in some scenarios of the dynamic environment monitoring system application, in a certain period of time, there may be a situation in which the first serial interface is not connected to the first device. In this case, the controller cannot obtain The monitoring control instruction of the first device can trigger the second DIP switch through the second trigger instruction described in this embodiment to make the serial port distribution device work in the configuration mode, and the second serial interface can be connected to an external configuration device, such as a computer By configuring the device, you can input the monitoring and control instructions of the first device to the controller, or modify the existing monitoring and control ins...

Abstract

The invention relates to a serial port distribution device for dynamic environment monitoring. The device comprises a controller, and a plurality of first serial interfaces and second serial interfaces. The first serial interfaces and the second serial interfaces are respectively connected with the controller, the first serial interfaces are used for being connected with first device, and the second serial interfaces are used for being connected with second device. The controller obtains a monitoring control instruction of the first device through the first serial interface under a first trigger condition. The controller obtains monitoring data of the second device through the second serial interface according to the monitoring control instruction under a second trigger condition. The controller receives the first trigger condition and stores the monitoring data, and when the controller obtains a monitoring control instruction of any first device under the second trigger condition, thecontroller sends the stored monitoring data corresponding to the monitoring control instruction to the first device obtaining the monitoring control instruction.

Description

Technical field [0001] The present disclosure relates to the technical field of serial interfaces, in particular to a serial port distribution device for dynamic loop monitoring. Background technique [0002] In the prior art, serial interface communication technology is a safe and reliable communication technology, which is widely used in civil aviation, industrial control and other fields.
