[0002] In the prior art, the human-machine remote communication technology uses a relative time method to monitor the network delay status, such as detecting the signaling loopback time. For example, the control device sends control signaling to the machine device and records the sending time. The mechanical device returns a response signaling after receiving the control signaling, and the control device records the receiving time after receiving the response signaling, and then the control device performs aging processing through its own receiving time and sending time, and its time reference system is the control device itself. The method cannot directly process the timeliness of control information and related reference information in the man-machine remote communication scene, so the timeliness of transmitting information is low when the network delay is unstable
For example, control devices and mechanical devices are easy to receive and use failure information caused by long delays

Embodiment 1
[0037] An embodiment of the present invention provides a method for judging aging, such as figure 1 shown, including:
[0038] S101. The control device receives machine-side information with a second absolute time stamp sent by the machine device.
[0039] The second absolute time is the absolute time when the machine device sends the machine-side information.
[0040] S102. The control device obtains the absolute time of the control terminal.
[0041] The control end absolute time is the absolute time when the control device receives the machine end information with the second absolute time stamp sent by the machine device.
[0042] S103. The control device performs aging processing on the machine-side information with the second absolute time stamp by using the absolute time of the control terminal, the second absolute time stamp, and the preset aging judgment rule.
[0043] In this way, the control device directly processes the timeliness of the relevant reference inform...

[0094] An embodiment of the present invention provides a method for judging aging, such as Figure 4 shown, including:
[0095] S401. The machine device receives control terminal information with a first absolute time stamp sent by the control device.
[0096] The first absolute time is the absolute time when the control device sends the control terminal information.
[0097] S402. The machine device obtains the absolute time of the machine end.
[0098] The machine-side absolute time is the absolute time when the machine device obtains the control-side information with the first absolute time stamp sent by the control device.
[0099] S403. The machine device performs aging processing on the control terminal information with the first absolute time stamp by using the machine terminal absolute time, the first absolute time stamp, and the preset aging determination rule.
[0100] In this way, the machine device directly processes the timeliness of the relevant reference info...

Abstract
The embodiment of the invention provides a time efficiency discrimination method, a control device and a mechanical device, relating to the communication field, and the timeliness of transmitting information can be raised. The time efficiency discrimination method comprises the following steps: the control device receives machine terminal information with a second absolute time stamp sent by the mechanical device, the second absolute time is an absolute time when the mechanical device sends the machine terminal information; the control device obtains a control terminal absolute time which is an absolute time when the control device receives the machine terminal information with the second absolute time stamp sent by the mechanical device; the control device carries out time efficiency processing on the machine terminal information with the second absolute time stamp through the control terminal absolute time, the second absolute time stamp and a preset time efficiency discrimination rule. The time efficiency discrimination method, the control device and the mechanical device provided by the embodiment are used for man-machine communication.
