Detailed Description
In order to make the objects, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are some, but not all, embodiments of the present invention. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
An embodiment of the present invention provides a specific implementation manner of a lighting control method, and referring to fig. 1, the lighting control method specifically includes the following steps:
step 100: and continuously acquiring an infrared detection state signal at an entrance of a target indoor space provided with the lighting equipment.
In step 100, the controller continuously acquires an infrared detection state signal at an entrance of a target indoor space where the lighting device is provided. It can be understood that, the controller is connected with the lighting device communication of the target indoor space, also with the infrared detection device communication that sets up at the target indoor space entrance, be used for receiving the infrared detection status signal that infrared detection device sent, and infrared detection device can be infrared diffuse reflection geminate transistor, wherein, infrared light pipe in the infrared diffuse reflection geminate transistor is when being blocked by the human body, the infrared ray that its sent can take place the diffuse reflection, see fig. 2, when a bundle of parallel incident light struck to rough surface, the surface can be towards the reflection of all directions to light, so the incident line is parallel to each other, because the normal direction of each point is inconsistent, causes the random reflection of reflected light to different directions, can produce the diffuse reflection promptly.
It can be understood that, since a single group of infrared diffuse reflection pair tubes can only detect whether there is shielding light, and cannot detect whether a person enters or exits, one infrared detection status signal in this embodiment may include a plurality of status signals, where 2 status signals included in the one infrared detection status signal are emitted by two groups of infrared diffuse reflection pair tubes disposed at an entrance of a target indoor space at the same time, or 3 status signals included in the one infrared detection status signal are emitted by more than three groups of infrared diffuse reflection pair tubes disposed at an entrance of a target indoor space at the same time.
In order to save the cost of lighting control, in this embodiment, the infrared detection status signal is preferably a status signal sent by two sets of infrared diffuse reflection geminate transistors disposed at the entrance of the target indoor space at the same time, and in an example, the relationship between the specific status signal and the infrared detection status signal is shown in table 1:
TABLE 1
In addition, in step 100, there may be two ways for the controller to continuously acquire the infrared detection status signal, the first way is that the infrared detection device sends its own status signal to the controller in real time, and since the time for the person to enter or exit the target indoor space is very short, the time interval for the controller to continuously acquire the infrared detection status signal should also be set according to the average speed of the person walking, specifically, the infrared detection device may be set to send its own status signal to the controller every 0.05 seconds, but for the target indoor space with low night or people flow, this way obviously consumes a lot of power of the infrared detection device and the controller and reduces the service life, so the second way may be preferably adopted, that is: the infrared detection device comprises two groups of infrared diffuse reflection geminate transistors, when one group of infrared diffuse reflection geminate transistors detects that infrared light emitted by the infrared detection device is shielded, the infrared detection device and the other group of infrared diffuse reflection geminate transistors are controlled to simultaneously and continuously send state signals to the controller, the two groups of infrared diffuse reflection geminate transistors simultaneously send respective state signals to the controller to jointly form one infrared detection state signal, and the time for continuously sending the state signals can be preset, so that the power consumption of the infrared detection device and the power consumption of the controller are reduced, and the service life of the infrared detection device and the controller are prolonged.
Step 200: and converting each infrared detection state signal into a corresponding binary state signal.
In step 200, when controlling to acquire the infrared detection status signals sent by the infrared detection device, each received infrared detection status signal is converted into a binary status signal in real time. It can be understood that the binary state signal is obtained by binary encoding conversion, and for the case that the infrared detection state signal is a state signal sent by two groups of infrared diffuse reflection geminate transistors arranged at the entrance of the target indoor space at the same time, it is obvious that the corresponding binary state signal is a two-bit binary state signal.
Step 300: initializing the preset values of an entry mark and an exit mark to be 0, then sequentially judging the signal type of each binary state signal, if the current binary state signal is an entry signal, adding 1 to the value of the entry mark, and subtracting 1 from the value of the exit mark, and if the current binary state signal is an exit signal, subtracting 1 from the value of the entry mark, and adding 1 to the value of the exit mark.
In step 300, in order to accurately and real-timely determine whether a person enters or exits the target indoor space, the controller prestores an entry flag and an exit flag, initializes the values of the entry flag and the exit flag to 0 before the start of the current determination period, and then sequentially determines the signal types of the binary state signals, where the signal types include an entry signal and an exit signal.
It can be understood that the manner of determining the signal type of each binary status signal is not unique, and may include determining the signal type of the current binary status signal by referring to the previous binary status signal of the current binary status signal, determining the signal type of the current binary status signal by referring to the next binary status signal of the current binary status signal, or determining the signal type of the current binary status signal according to the pre-obtained sequence of the corresponding binary status signals entering or exiting, which is preferably implemented in the first manner in this embodiment, and specifically refer to the following specific implementation manner regarding the determination process in step 300.
Step 400: after the signal type of each binary state signal is determined, whether the values of the current entering mark and the exiting mark are equal to a preset value or not is judged, if the value of the entering mark is equal to the preset value first, it is judged that a person enters the target indoor space at present and the lighting equipment in the corresponding control target indoor space is turned on, and if the value of the exiting mark is equal to the preset value first, it is judged that the person exits the target indoor space at present and the lighting equipment in the corresponding control target indoor space is turned off.
In step 400, after the signal type of each binary state signal is determined in sequence, it is determined whether the values of the current entry flag and the exit flag are equal to the preset value, it is determined whether a person enters or exits the target indoor space, if the value of the entry flag is equal to the preset value first, it is determined that the person enters the target indoor space and the lighting device in the corresponding control target indoor space is turned on, if the value of the exit flag is equal to the preset value first, it is determined that the person exits the target indoor space and the lighting device in the corresponding control target indoor space is turned off, and after it is determined that the person enters or exits the target indoor space, the process returns to step 300, i.e., steps 300 and 400 are repeatedly executed, and a new round of determination of the signal type of the binary state signal is performed again.
As can be seen from the above description, the lighting control method provided in the embodiments of the present invention can accurately and real-timely determine whether a person enters or exits the target indoor space, and thus can accurately and efficiently automatically control the lighting devices in the target indoor space.
In one embodiment, step 100 in the lighting control method of the present invention specifically includes the following steps:
continuously receiving state signals sent by high-level infrared detection equipment and low-level infrared detection equipment which are arranged at the inlets of target indoor spaces, wherein the state signals sent by the high-level infrared detection equipment and the low-level infrared detection equipment at the same time form the infrared detection state signals; the linear distance from the high-level infrared detection device to the entrance of the target indoor space is greater than the linear distance from the low-level infrared detection device to the entrance of the target indoor space. It will be appreciated that both the high infrared detection device and the low infrared detection device may preferably be infrared diffusely reflecting light pipes.
As can be seen from the above description, the lighting control method according to the embodiment of the present invention can determine whether a person enters or exits the target indoor space in real time by setting the two infrared detection devices, so as to efficiently and automatically control the lighting devices in the target indoor space.
In one embodiment, the status signal is a first signal indicating that the infrared ray is blocked or a second signal indicating that the infrared ray is not blocked, and the binary code of the first signal is 1 and the binary code of the second signal is 0; the step 200 in the lighting control method of the present invention specifically includes the following contents:
if the infrared detection state signal comprises two second signals, converting the infrared detection state signal into a first binary state signal: 00.
if the infrared detection state signal comprises a second signal sent by a high-order infrared detection device and a first signal sent by a low-order infrared detection device, converting the infrared detection state signal into a second binary state signal: 01.
if the infrared detection state signal comprises a first signal sent by a high-order infrared detection device and a second signal sent by a low-order infrared detection device, converting the infrared detection state signal into a third binary state signal: 10.
if the infrared detection state signal comprises two first signals, converting the infrared detection state signal into a fourth binary state signal: 11.
the specific binary status signal mapping relationship is shown in table 2 below:
TABLE 2
Therefore, based on the above table 2, referring to fig. 3, step 300 in the lighting control method of the present invention specifically includes the following steps:
step 301: initializing the values of a preset entry mark and an exit mark to 0;
step 302: based on a preset rule and according to a previous binary state signal of the current binary state signal, judging whether the signal type of the current binary state signal is an entering signal or an exiting signal; if the current binary state signal is an entry signal, go to step 303; if the current binary status signal is an exit signal, go to step 304.
Step 303: the value of the entry flag is incremented by 1 and the value of the exit flag is decremented by 1.
Step 304: the value of the entry flag is decremented by 1 and the value of the exit flag is incremented by 1.
It is understood that the preset rules include: a first rule: the sequence of occurrence of the binary status signals when someone enters the target indoor space is: 00. 01, 11, 10 and 00; and, a second rule: the sequence of occurrence of the binary status signals when someone exits the target indoor space is: 00. 10, 11, 01 and 00.
If the current binary state signal and the previous binary state signal meet the first rule, the current binary state signal is judged to be an entering signal, and an entering mark is added and an exiting mark is reduced.
If the current binary state signal and the previous binary state signal meet the second rule, the current binary state signal is judged to be an exit signal, and an entry mark is decreased and an exit mark is increased.
As can be seen from the above description, the illumination control method according to the embodiment of the present invention provides an accurate data base for subsequent statistical marking by accurately determining the signal type, so as to implement automatic, intelligent, and remote illumination control.
In one embodiment, referring to fig. 4, step 400 of the lighting control method of the present invention specifically includes the following:
step 401: and after the signal type of each binary state signal is determined, acquiring the number of the entry marks and the exit marks in real time and judging whether the values of the current entry marks and the exit marks are equal to 4 or not.
If the number of entry flags is equal to 4 before the exit flag, go to step 402; if the number of exit flags is equal to 4 before the entry flag, step 403 is entered.
Step 402: it is determined that a person currently enters the target indoor space, and the number of persons in the current target indoor space is increased by 1, and then the process proceeds to step 404.
Step 403: it is determined that the person currently exits the target indoor space, and the number of persons in the current target indoor space is decreased by 1, and then the process proceeds to step 404.
Step 404: and judging whether the number of the personnel in the current target indoor space is 0, if so, entering a step 405, and otherwise, entering a step 406.
Step 405: controlling the lighting devices in the target indoor space to be turned off.
Step 406: and controlling the lighting equipment in the target indoor space to be turned on.
From the above description, it can be known that the lighting control method of the embodiment of the present invention can accurately and real-timely determine whether a person enters or exits the target indoor space, and further can accurately and efficiently automatically control the lighting device in the target indoor space, so as to achieve real automation, intellectualization, and remoteness, and finally achieve the energy saving requirements of cost saving, energy consumption reduction, and environmental protection, and can effectively improve and manage the use of the lighting device, effectively reduce the power consumption of lighting, and save the lighting cost.
To further explain the scheme, the present invention further provides an application example of the lighting control method, taking the target indoor space as a machine room in a communication building as an example, specifically including the following contents:
through intelligent control's mode, at the computer lab gate of communication machine building, the infrared diffuse reflection geminate transistor of installation, but this infrared diffuse reflection geminate transistor automated inspection computer lab has personnel's business turn over, and can count the number in the room, and under the condition of someone in the computer lab, the automatic light that switches on of controller, when all personnel withdraw the computer lab in the computer lab, the automatic light that closes of controller has avoided the artificial extravagant phenomenon such as forgetting to close the light.
In the practical application process, many scenes of invalid signals often occur, for example, before a person needs to enter a machine room, after touching a first light pipe, if other tools forgotten to hold or other reasons exist in the middle, the person exits the machine room without touching a second light pipe, which is an invalid signal, that is, when only one light pipe is touched, the entering and exiting process is interrupted, and the invalid signal should be eliminated in a control system. For another example, as an electronic product, some interference signals may occur, and the resulting invalid signals should be eliminated.
By means of binary coding, it is assumed that the output of infrared diffuse reflection is 0 when there is no blocking signal, and the output is 1 when there is a blocking signal, i.e. the correct and valid incoming signal should be: 00-01-11-10-00, the effective exit signals are: 00-10-11-01-00. As long as both of these in and out sequences are met, both are valid signals. The effective incoming signal is explained as follows: when no shielding signal exists, the output of the infrared diffuse reflection geminate transistor is 00, when a person enters a machine room, the person must touch a low-level signal of the geminate transistor firstly, the low-level signal is output 1, namely the geminate transistor is output 01, when the person continues to move forwards, the geminate transistor is closer to the arrangement position, when the person touches a high-level light tube, the low-level light tube is touched, the output of the geminate transistor is 11, the person continues to enter the machine room, the low-level light tube is held, the output signal of the geminate transistor is 10, and when the person finally enters the machine room, the output of the geminate transistor is 00. The same is true for the exit signal. If the controller receives the following signals: 00-01-11-10-00, which is a valid signal even if there are more partially unrelated sequences in the middle, when the overall sequence satisfies the valid entry sequence signal.
Referring to fig. 5, fig. 5 is a schematic diagram of a detection algorithm for in-out detection signals, which utilizes a labeled algorithm to circularly judge a current state, classify each situation, confirm an effective signal, and in the algorithm, on the basis of confirmation of the effective sequence, exclude an irrelevant sequence, so that the detection signals are more accurate, and in fig. 5, N is a current state value, B is a previous state value, IM is a flow sequence entry effective value, OC is a flow sequence exit effective value, IC is an entry label mark, and OC is an exit label mark. Briefly, this detection algorithm is mainly based on identifying the comparison between the current tube occlusion state and the last occluded state.
Referring to fig. 6, fig. 6 is a detection sequence of a normal entry signal, the status of both the pair transistors is 00 at the beginning, which indicates that both are occluded, the value of the current NOW is assumed to be 0, in the process of first, the pair transistor status is detected to be 01, the value of the current NOW is 1, the status of the pair transistor in the last state is 00, and the value of becure is 1, then a normal sequence change is recorded, the entry valid value IM is 1, and the entry flag IC valid value is added by 1. After 4 times of the process, when the entering mark is increased to 4 times, the detection process is proved to be completed, and the accurate entering signal is returned when the personnel really enter.
Referring to fig. 7, fig. 7 is a sequence of detection of an abnormal entry signal, which can be explained in such a manner that a person intending to enter the machine room, when passing through the doorway in preparation for complete entry, suddenly and inadvertently trips one step back on the foot, and then re-enters the machine room. The sequence detected by the controller in the process is as shown in the sequence of fig. 7, the same entering process is only the middle point wave, but the last person finishes the entering process, and is an effective sequence, after the process III is finished, the entering mark IC is increased to 3, at this time, because the person is returned to one step, after the process IV is added, the IC is automatically reduced by 1, and enters the machine room again for repeating the process III, namely, the process IV is finished, and then the process IV is finished, so that the valid signal which really and completely enters the machine room is obtained.
Referring to fig. 8, fig. 8 illustrates the process of eliminating invalid incoming signals. The process can be explained as that when a person enters the machine room and shields the two light pipes, the person suddenly reminds that a tool is not taken, and the person immediately turns back to take the tool. This process appears to the controller as the sequence of fig. 8. After the process (ii), the entering tag IC is increased to 2, and the entering tag IC is decreased to 0 because of the process (iii). The entry is invalid. Through the algorithm, accurate detection of personnel entering can be completed, various invalid entering and exiting sequences can be eliminated, and accurate calculation of the number of people is achieved.
From the above description, it can be seen that the illumination control method of the application example of the present invention performs binary coding on the shielding signal by solving the problem of removing the invalid signal, mainly by means of an optimization program algorithm, and removes the invalid signal by distinguishing the real valid signal from the invalid signal, thereby improving the detection accuracy, realizing the real automation, intellectualization and remoteness, and finally realizing the energy saving requirements of cost saving, energy consumption reduction and environmental protection. Therefore, by means of technical innovation, the use of a large number of lamp tubes is improved and managed, the lighting power consumption can be greatly reduced, and the lighting cost is saved.
An embodiment of the present invention provides a specific implementation manner of an illumination control system capable of implementing all steps in the illumination control method, and referring to fig. 9, the illumination control system specifically includes the following contents:

And the lighting device control module 40 is configured to, after determining the signal type of each binary state signal, determine whether values of the current entry flag and the exit flag are equal to preset values, determine that a current person enters the target indoor space and turns on the lighting device in the corresponding control target indoor space if the value of the entry flag is equal to the preset value first, and determine that the current person exits the target indoor space and turns off the lighting device in the corresponding control target indoor space if the value of the exit flag is equal to the preset value first.
