Description
Technical Field
The invention relates to the technical field of routers, in particular to a method and a device for displaying the working state of a router based on the display effect of an LED lamp.
Background
With the development of mobile internet, routers have gradually moved to each household as a bearer of a network. The existing router product is usually provided with a plurality of indicator lamps for indicating the working state of the router, the working state of the router is represented through the indicator lamps, one or more GPIO ports are LED out from the main control chip of the router to serve as control ports of the LED, and level signals and level duration time corresponding to the working state are output to the GPIO ports. Therefore, the user can judge the working state of the router through the color and the flashing frequency of the LED lamp so as to know whether the working has problems and quickly check the problems of the router.
Generally, a router gives an indicator light corresponding to each WAN/LAN port and 1-2 indicator lights corresponding to a network card, a port or a network card data transmission effect is displayed through the flashing of the indicator lights, the indicator lights corresponding to the WAN/LAN ports and the network card are always on to indicate normal connection/normal work, the flashing of the indicator lights indicates that data transmission exists, and the flashing of the indicator lights is faster when the data transmission rate is higher and the synchronization with data streams of transmission data is realized, so that a user can visually know the data transmission condition through the indicator lights.
However, at different transmission rates, the indicator light is only different in frequency and the brightness remains substantially uniform. The flicker frequency which can be perceived by human eyes is limited (generally, human eyes cannot perceive flicker for the refresh frequency above 80 Hz), and when the indication frequency is more than 50Hz, the human eyes can generate the effect of visual persistence, and basically cannot see flicker. That is to say, the change of the transmission rate cannot be obviously sensed by the user simply by means of the change of the flicker frequency, and the judgment of the working state of the router by the user is not facilitated, so that most users do not choose to judge the data transmission rate by the flicker of the indicator light, and much more data transmission rate of the router is judged by the state information displayed on the GUI interface of the router, and the mode is single.
Therefore, it is necessary to improve the operation state of the route displayed by the indicator light, especially the rate change in the data transmission state displayed by the indicator light, so as to provide a new selectable way for the user to know the operation state of the route and optimize the use experience of the route.

Detailed Description
The invention is described in detail below with reference to the figures and the specific embodiments.
The method provided by the invention is applied to a router main chip, the chip can adopt an MT7621 chip or other chips of the same type, the router main chip can determine the duty ratio D1 and the period T1 of the PWM signal through the acquired data transmission rate V, the duty ratio D1 correspondingly controls the brightness of the LED indicator lamp, the period T1 correspondingly controls the flicker frequency of the LED indicator lamp, the PWM signal determined in the way can simultaneously control the brightness and the flicker frequency of the LED indicator lamp, so that a user can know the data transmission rate V from the two aspects of the brightness and the flicker frequency of the LED indicator lamp, and the user can obtain more accurate feedback and improve the use experience of the user.
Specifically, as shown in fig. 1, the method includes the steps of:
step 1, the current data transmission rate V of the router is read by the main chip of the router.
Step 2, the router master chip determines a PWM signal according to the data transmission rate V, and the method comprises the following steps:
determining a transmission rate level LV to which the data transmission rate V belongs according to the size of the data transmission rate V;
determining a preset duty ratio Dp corresponding to the transmission rate level LV according to the transmission rate level LV, and taking the preset duty ratio Dp as a duty ratio D1 of the PWM signal;
and determining a preset period Tp corresponding to the transmission rate level LV according to the transmission rate level LV, and taking the preset period Tp as the period T1 of the PWM signal.
It should be understood that, in the embodiment of the present invention, the transmission rate level LV, the preset duty ratio Dp, and the preset period Tp are not limited, and may be specifically set according to an actual situation. Illustratively, the transmission rate class LV includes three classes, I, II and III, which respectively correspond to 10M class, 100M class and 1000M class, where 10M class means that the transmission rate is within 100Mbps, 100M class means that the transmission rate is between 100mbps and 1000mbps, and 1000M class means that the transmission rate is above 1000 Mbps.
The preset duty ratio Dp corresponding to the I-level transmission rate is 10%, the preset period Tp is 100ms, the preset duty ratio Dp corresponding to the II-level transmission rate is 50%, the preset period Tp is 40ms, the preset duty ratio Dp corresponding to the III-level transmission rate is 90%, and the preset period Tp is 20ms.
That is to say, the smaller the transmission rate level LV is, the smaller the corresponding data transmission rate is, the smaller the duty ratio D1 of the PWM signal determined by the level LV is, and the larger the period is, and the larger the duty ratio is, the smaller the brightness of the corresponding product is, and the larger the period is, the slower the corresponding flicker frequency is. Therefore, when a user observes the dimming of the LED indicator lamp and the flicker frequency is very low, the current data transmission rate can be determined to be poor; if the LED indicator is bright and the flashing frequency is fast, it can be determined that the current data transmission rate is excellent.
In one embodiment of the invention, the preset period Tp is more than or equal to 20ms and less than or equal to 100ms, the flicker frequency is determined to be within the range of 10hz to 50Hz based on the preset period, and a user can perceive the flicker frequency within the range more obviously.
And 3, the router main chip outputs the PWM signal determined in the step 2 to a control port of the LED indicator lamp through one GPIO port of the router main chip so as to control the LED to work according to the PWM signal.
In the step 1, the data transmission rate V is an average transmission rate read in one acquisition period T2, the acquisition period T2= nT1, n is greater than or equal to 5, so that subsequent LED indication and the like can have enough transition time to perform gradual dimming or variable dimming, and the brightness of the LED indicator lamp is prevented from sudden change in a short time.
And in an acquisition period T2, gradually increasing the duty ratio D1 from the minimum duty ratio Dmin to the corresponding preset Dp. That is to say, the LED pilot lamp is the gradual brightening in the course of the work to it is the injury to the eyes to reduce the user to look over, makes the user have a practical process.
It should be noted that, when the data transmission rate V is an average transmission rate read in one acquisition period T2, the current display effect of the LED indicator is a result of the PWM signal operation determined based on the previous acquisition period, and is not the PWM signal determined by the current acquisition period.
Preferably, an increase rate R of the data transmission rate in the current acquisition period T2 is calculated, and the period T1 of the PWM signal is adjusted according to the increase rate R, so that the change of the blinking frequency of the LED is synchronized with the data transmission rate, so that the user can directly know the change of the increase rate of the current data transmission rate through the change of the blinking frequency. Specifically, if R is less than or equal to-Rp, the period T1 of the PWM signal is gradually increased in the next acquisition period; if R is more than-Rp and less than or equal to Rp, keeping the period T1 of the PWM signal unchanged in the next acquisition period; if R is larger than Rp, gradually reducing the period T1 of the PWM signal in the next acquisition period; wherein the Rp is a minimum increase rate of the data transmission rate.
Preferably, when the period T1 of the PWM signal is gradually increased in the next acquisition period, the period T1 is gradually increased from the minimum period Tmin; when the period T1 of the PWM signal is gradually decreased in the next acquisition period, the period T1 is gradually decreased to the minimum period Tmin. Therefore, the change of the flicker frequency is more natural and smooth, and the use experience of the route is improved.
