Description

Technical Field

[0001] The present invention relates to the field of lighting control systems, and more specifically, to an integrated pipe gallery intelligent lighting control system based on Internet of Things technology. Background Art

[0002] With the continuous development of my country's infrastructure, the laying area of ​​pipelines is getting longer and longer. In the construction of pipelines, the lighting system is one of the indispensable infrastructures. At present, most of the lighting control systems used in pipelines are traditional hanging lamp tube structures or manual switch structures. After long-term use, the damage rate is high and the maintenance cost is high. The most important thing is that they cannot be maintained in time.

[0003] Through patent search, it was found that the publication number is: CN204948481U. This patent can only perform multiple tests in addition to lighting, and has great limitations in practical applications. Moreover, it is not stable enough when installing lighting equipment. At present, some pipe corridor lighting lamps are installed in a suspended manner. With the aging of cables and natural factors, the lighting lamps are prone to fall off, causing the cables to pull the lighting lamps to be suspended in the air, which poses a great safety hazard. Moreover, if the lighting lamps are damaged, power outages or other natural disasters occur in traditional pipe corridors, the lighting lamps cannot be used to provide evacuation directions for staff, resulting in low efficiency.

[0049] See also Figure 2 , the operation of the control unit includes the following steps:

[0050] Step 1: The control unit connects to the remote distance measurement module for distance measurement;

[0051] Step 2: The remote ranging module inputs the signal into a four-input latch;

[0052] Step 3: The decoder amplifies the signal and performs analog-to-digital conversion;

[0053] Step 4: The converted signal is displayed on the display 8;

[0054] See also Figure 3 In step 1, the laser rangefinder is operated through the remote distance measurement module, and the distance measurement laser emitted by the laser rangefinder is aimed at the next lighting lamp 7. At this time, the distance signal can be recorded by the background processor.

[0055] See also Figure 2 , Figure 3 , Step 2 The input process includes the following steps:

[0056] a: wirelessly input the distance information between the lighting lamps 7 to the four-input latch via the ZigBee local area network protocol;

[0057] b: When the input latch receives a signal, D, C, B, and A input the 8421 code, and the corresponding display screen displays numbers from 0 to 9, and the corresponding turn signal lights up;

[0058] Among them, when LE is in a low power state, the states of the input terminals A, B, C, and D are entered into the latch; when LE is turned to a high power state, the entered data is locked in the trigger.

[0059] DPI is the decimal point control terminal. When it is at a high level, the decimal point lights up, and when it is at a low level, the decimal point goes out.

[0060] BL is the display or blanking control terminal. When it is high level, the digital and decimal point are unconditionally blanked, otherwise, they are displayed;

[0061] RBI is used to control the blanking of invalid zeros. When RBI=0, DPI=0, and the latch content is zero, it will not be displayed. At this time, RBO outputs a low level.

[0062] See also Figure 2 , Figure 3 In step 3-4, after the decoder receives the 8421 code, it first amplifies the collected signal, corrects part of the collected signal, and then converts the collected signal into a digital signal for output, so that the converted collected signal generates a signal that can be recognized by the display 8 and is displayed on the display 8 in digital form.

[0063] Among them, the decoder is a BCD seven-segment decoder. The input of the BCD seven-segment decoder is a BCD code (expressed by D, C, B, A), and the output is the driving signal of each segment of the digital tube (expressed by Fa Fg), also known as a 4-7 decoder;

[0064] If it is used to drive a common cathode LED digital tube, the output should be high effective, that is, when the output is high (1), the corresponding display segment lights up. For example, when the 8421 code DCBA = 0100 is input, 4 should be displayed, that is, it is required to light up segments b, c, f, and g at the same time, and extinguish segments a, d, and e. Therefore, the output of the decoder should be Fa Fg = 0110011, which is also a group of codes, often called segment codes. Similarly, according to the requirements of forming the 10 glyphs 0-9, the truth table of the 8421BCD seven-segment decoder can be listed (see Appendix). Figure 7 ); The numbers on the display 8 and the turn signal lights can be controlled simultaneously according to this principle.

[0065] When in use: first install the junction box 1 in the installation groove 3, then rotate the rotating plates 23 on both sides to drive the screw 22 to rotate, the screw 22 drives the second trapezoidal block 20 to move upward, the second trapezoidal block 20 supports the first trapezoidal block 18, and the first trapezoidal block 18 and the second trapezoidal block 20 are inclined. The first trapezoidal block 18 moves on both sides, and the first trapezoidal block 18 drives the top plate 19 to press against the side wall of the installation groove 3 through the movable rod 17, so that the junction box can be installed conveniently and stably;

[0066] At the same time, when the second trapezoidal block 20 rises, the vertical rod 24 is driven to move upward, and the vertical rod 24 drives the push plate 26 to squeeze the caulking agent 27. The caulking agent 27 is squeezed and overflows from the through hole 28 to contact the mounting groove 3, filling the gap between the junction box 1 and the mounting groove 3, thereby improving its firmness.

[0067] When a power outage, damage to the lighting lamp 7 or a natural disaster occurs in the tunnel, the control unit can control the display information on the display 8, so that the direction and distance information on the display 8 are projected onto the ground through the projection mechanism using the imaging principle, which is convenient for the staff to observe and evacuate or repair the lighting lamp 7 according to the instructions, thereby effectively improving its use efficiency.

[0068] The above is only a preferred specific implementation of the present invention; however, the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes according to the technical solution and its improved conception within the technical scope disclosed by the present invention, which should be covered by the protection scope of the present invention.
