Problems solved by technology

Chinese invention patent CN201210205514.1 proposes to use the input device to input dimming display instructions to reduce the brightness of the display, thereby reducing power consumption and prolonging the service life, but this solution only uses the characteristics of the display itself and does not make full use of the use Environment to achieve energy saving and prolong service life; Chinese invention patent CN201310723713.6 proposes to use the "afterglow effect" of the human eye to display in group alternate lighting mode during the afterglow time to reduce the power consumption of the display and prolong its service life, but the scheme It only uses the "afterglow effect" of the human eye, and does not use the display itself and the use environment to achieve energy saving and prolong service life; Chinese invention patent CN201010113793.X, Chinese invention patent CN201010113803.X and Chinese invention patent CN201010253215.6 were proposed and approved Turn off the elevator operation information display on the non-passenger floor to reduce energy consumption and prolong the service life of the display. However, this solution will cause passengers to be unable to know the elevator operation status information before pressing the call button because the elevator operation information display is in a power-off state, and then Make passengers mistakenly think that the elevator is in a non-service state; Chinese invention patent CN201210037293.1 proposes that all the display devices corresponding to the call registration devices that have not received valid call registration information display all or part of their display content in a low-brightness manner , so as to reduce the power consumption of the display and prolong its service life. Compared with the previous schemes, this scheme has a greater degree of improvement in energy saving and life extension.

Embodiment 1

[0055] like figure 2 As shown, the display device is a rectangular LED dot matrix screen composed of 5 (columns) × 7 (rows) totaling 35 LEDs (here, n=35, the display unit is an LED, and the display device is an LED dot matrix screen); The array screen uses a periodic method to display the information to be displayed. The period here can be a fixed period with a constant time length, or a non-fixed period with a variable time length. Suppose the original information to be displayed is figure 2 The black Arabic numeral "1" in.

[0056] In the normal display mode, the display device displays the original information to be displayed—the Arabic numeral "1" with normal size and brightness. After entering the specific display mode, the method for the display control device to control the display device to display information includes the following step:

[0057] Step 1, determine the quantity m of the working display unit of the display device (the working display unit refers to...

Embodiment 2

[0075] This embodiment is similar to Embodiment 1, except that the display positions of the working display units determined in step 2 are different. In this embodiment, the display positions of the working display units are reciprocated according to a certain rule (that is, the m display units on the display device are sequentially used as working display units).

[0076] image 3 What is shown is a schematic diagram of a working display unit cyclically changing its position on the display device according to a certain rule. As shown in the figure, the position of the illuminated working display unit moves to the right from the first row and the first column (corresponding to the first display unit of the display device - LED dot matrix screen - LED) to the first After row 5, jump to row 2, column 1, and so on, until reaching row 7, column 5 (corresponding to the last LED of the LED dot matrix screen), and then complete this cycle, and then return to the first Line 1 column...

Embodiment 3

[0079] This embodiment is similar to Embodiment 1 or Embodiment 2, the difference lies in that the display manner of the information determined in step 4 is different.

[0080] In continuous k (as 2) display cycles, the working display unit (i.e. the selected LED) in the preceding i (as 1) cycles is extinguished (i.e. in a non-display state) and in the subsequent j (j=k-i ) (as described in 1) cycle, the display unit operates with a non-zero brightness λ (0max ) to display, so that the effect of flickering display can be realized.

[0081] Obviously, when the working LED is off (that is, its brightness λ=0), no LED is in the display state, and the number of display units (LEDs) in the display state is m=0, then the number of LEDs in the display state is m (m=0) and the total number of display units n (n=35) satisfy 0=m

Abstract

The invention discloses an information display method of an information display system. The information display system comprises a display device and a display control device for controlling the display device; the display device enables work display units to display information to be displayed in a periodic way. The information display method comprises the following steps of 1, confirming the amount of the work display units; 2, confirming the display positions of the work display units; 3, confirming the display ways of the work display units; 4, displaying information to be displayed; and 5, turning off the display units in a displaying state when the display period is ended. By using the information display method, an elevator information display system can be remarkably reduced in power consumption and effectively prolonged in service life on the premise of providing the information that an elevator is in a normal working state for passengers. The invention also discloses the information display system.

Description

technical field [0001] The invention relates to an information display method, in particular to an information display method of a display device composed of a plurality of display units. The invention also relates to an information display system. Background technique [0002] The elevator information display system is usually used to display passengers' destination floor and / or direction information, call registration device status, passenger registration information, elevator current operation information and other information that you want to provide to passengers. The common display method of the elevator information display system for the information to be displayed is continuous display with constant brightness. Obviously, this method has disadvantages such as high power consumption and short display life. [0003] Aiming at the shortcomings of common display methods, relevant literature provides various improvement schemes from different perspectives. Chinese inven...
