Wherein, by described step S222, if the judged result of described step S221 is sure, kill described first timer, determine that described video conference terminal is online, preferably, the presence that described video conference terminal is set is true, it is 0 that first timer expired times are set, and it is bright light that described LED status is set.If the judged result of described step S221 negates, next by carrying out described step S223, if the judged result of described step S221 negates, judge whether the overtime read-around ratio of described first timer exceedes Second Threshold, further, if the judged result of described step S223 is sure, the overtime read-around ratio of described first timer exceedes Second Threshold, next enters step S225 and continues to carry out; If the judged result of described step S223 negates that the overtime read-around ratio of described first timer does not exceed Second Threshold, next enters step S224 and continues to carry out.
Wherein, by carrying out described step S224, if the judged result of described step S223 negates to restart described first timer.If the judged result of described step S223 is sure, next by carrying out described step S225, if the judged result of described step S223 is sure, determine described video conference terminal chain rupture.Further, by described step S225, determine after described video conference terminal chain rupture, next perform step S226, close all or part of described indicator light.
Fig. 6 illustrates according to a fifth embodiment of the invention, the flow chart of the control method of the video conference terminal controller based on serial ports.The present embodiment shows described video conference terminal and how to detect the technical scheme of described video conference terminal controller chain rupture, and these steps preferably start repeatedly to carry out until described video conference terminal controller rolls off the production line after described video conference terminal controller is reached the standard grade.Particularly, in the present embodiment.First perform step S230, described video conference terminal starts second timer, the presence that described video conference terminal controller is set after described video conference terminal initialization is false, and second timer expired times are initialized as 0, and starting second timer and timing cycle is set is 2 seconds.Next enter step S231, whether judgement receives the described keepalive command from described video conference terminal controller before described second timer is overtime, further, if the judged result of described step S231 is sure, before described second timer is overtime, receive the described keepalive command from described video conference terminal controller, next enter step S232 and continue to carry out; If the judged result of described step S231 negates; before described second timer is overtime, do not receive the described keepalive command from described video conference terminal controller; described second timer expired times are increased to 1, and next enter step S233 continuation execution.
Wherein, by described step S232, if the judged result of described step S231 is sure, kills and restart described second timer, and determining that described video conference terminal controller is online, it is 0 that described second timer expired times are set.If the judged result of described step S231 negates, next by carrying out described step S233, if the judged result of described step S231 negates, judge whether the overtime read-around ratio of described second timer exceedes Second Threshold, further, if the judged result of described step S233 is sure, the overtime read-around ratio of described second timer exceedes Second Threshold, next enters step S235 and continues to carry out; If the judged result of described step S233 negates that the overtime read-around ratio of described second timer does not exceed Second Threshold, next enters step S234 and continues to carry out.
Wherein, by carrying out described step S224, if the judged result of described step S233 negates to restart described second timer.By carrying out described step S235, if the judged result of described step S233 is sure, determine the chain rupture of described video conference terminal controller.
Further, with reference to above-mentioned Fig. 7 and Fig. 8, the video conference terminal that video conference terminal controller provided by the invention is corresponding with it completes communication process in the following way:
1) the state notifying video conference terminal that video conference terminal controller only need to be pressed button, by video conference terminal, be responsible for lighting a lamp (except system running indicator/online lamp), video conference terminal controller only just cuts out all lamps after chain rupture being detected.The state of system running indicator/online lamp is responsible for maintenance by video conference terminal controller.Those skilled in the art are appreciated that in conjunction with prior art and above-described embodiment state representation talking state or the non-talking state that button is pressed or is not pressed; Similarly, system running indicator/online lamp also represents respectively corresponding state, does not repeat them here;
2) video conference terminal controller needs timed sending keepalive command always after starting, so that video conference terminal detects.Those skilled in the art are appreciated that preferably in conjunction with prior art and above-described embodiment, and keepalive command is 4 bytes.Correspondingly, the sending order of keepalive command can according to implement need determine, for example preferably, it is 0xFF according to the banner word of sending order, command word is 0xEE; Correspondingly, follow-up parameter word, check word can need to determine according to implementing, and do not repeat them here;
3) utilizing keepalive command to do chain rupture detects.Particularly, be divided into again following several step:
3.1) chain rupture of video conference terminal detects.As shown in Figure 7; video conference terminal will add the function that a chain rupture detects; after receiving keepalive command, respond a keepalive command; if current Mtc_Box presence is vacation, refresh indicator light; it is true that Mtc_Box presence is set, and closes chain rupture and detects timer and restart this timer.If continuous three chain ruptures detect timer timeout, think chain rupture of Mtc_Box, it is false that Mtc_Box presence is set;
3.2) chain rupture of video conference terminal controller detects.As shown in Figure 8, after the initialization of video conference terminal controller, start keep-alive timer, timed sending keepalive command.If send continuously 10 (preferred number of times, yet can according to implementing to determine this number of times) keepalive commands, all do not receive the keepalive command response of MT, think chain rupture.After chain rupture being detected, need the state of all lamps to be made as and to close.The interval of keep-alive timer is temporarily made as 0.5 second, if promote the sensitivity that chain rupture detects, this value further can be established littlely, for example 0.2 second, does not repeat them here.
Above specific embodiments of the invention are described.It will be appreciated that, the present invention is not limited to above-mentioned specific implementations, and those skilled in the art can make various distortion or modification within the scope of the claims, and this does not affect flesh and blood of the present invention.
