[0003] The above-mentioned existing technical solutions have the following defects: the above-mentioned signboard is illuminated by LED lights when there is no light around the signboard during use, but the on-off control of the above-mentioned signboard LED lights is through the LED drive circuit. When the LED lights are turned on, the LED drive circuit must be switched manually, and in a day, the ambient brightness will be dimmed or brightened with time, so it is necessary to turn off the LED lights during the brightening period, and to Turn on the LED light, the whole process is more troublesome, it needs to be improved

Embodiment 1
[0047] refer to figure 1 , figure 2 , is a replaceable sign disclosed in the present invention, comprising a column 1, a sign body 2 screwed to the top of the column 1, and a number of LED lamps 19 evenly distributed on the side wall of the sign body 2.
[0048] The sign body 2 is equipped with a control system 3 that controls the LED lights 19 to automatically turn on and off to light up or turn off to dim. The control system 3 includes a control terminal 4, an ambient brightness sensing module 5, a time period calculation module 7, a comparison module 8, and an information transmission module 9 And the ambient brightness threshold database 6, the ambient brightness threshold database 6 is used to provide the brightness reference threshold corresponding to the first time period (6~8 o'clock) in a day; the brightness reference threshold value of the second time period (8~18 o'clock); Brightness reference thresholds for three time periods (18~6 o'clock).
[0049] The control...
Embodiment 2
[0056] A method for replacing a sign, comprising:
[0057] Step 1: Power on and use, power on the sign body to make several LED lights glow or turn off during the corresponding time period of the day;
[0058] Step 2: System detection, through the database recorded in the control information recording module for the lighting conditions of LED lights, the sign body can be replaced when any one of the delayed shutdown warning module or the quick trigger warning module gives an alarm;
[0059] Step 3: Disassembly of the signage, take out the bolts from the column to release the connection between the signage body and the column, so that the signage body and the column are separated from each other, and then remove the signage body from the column;
[0060] Step 4: Clean the top of the column, use a cleaning brush to clean the installation position of the sign body to remove the peeling paint and adhered dust on the column;
[0061] Step 5: Column repair, re-spray the paint on th...

Abstract
The invention relates to a replaceable signboard and a replacement method thereof, comprising a column, a signboard body, a control system is arranged in the signboard body, and the control system includes a control terminal, an ambient brightness sensing module, an ambient brightness threshold database, a time period calculation module, a comparison module and information transmission module; the ambient brightness threshold database provides the brightness reference threshold corresponding to the first time period of the day; When the brightness reference threshold of a period of time, the LED lamp is in the low brightness stage, and when the ambient brightness of the sign body is greater than the brightness reference threshold of the first period of time and less than the brightness reference threshold of the second period of time, the LED lamp is in the off stage, and the sign body When the brightness of the surrounding environment is less than the brightness reference threshold of the third time period, the LED lamp is in a high brightness stage; the invention can automatically turn on or off the LED lamp in real time, so as to illuminate the signboard.
Description
technical field [0001] The invention relates to the technical field of signs, in particular to a replaceable sign and a replacement method thereof. Background technique [0002] Existing signboards, such as a Chinese utility model patent whose notification number is CN206639542U, disclose a signboard comprising a strip bracket and a light guide signboard, the upper end of the light guide signboard is detachably mounted on a strip On the bracket; there is an LED light strip at the connection between the strip bracket and the top of the light guide plate, and an LED drive circuit connected to the LED light strip inside, and the LED lamp beads on the LED light strip are facing the light guide Identify the upper face of the plate. [0003] The above-mentioned existing technical solutions have the following defects: the above-mentioned signboard is illuminated by LED lights when there is no light around the signboard during use, but the on-off control of the above-mentioned sign...
