detailed description

The invention will be described in detail below with reference to the drawings in conjunction with the embodiments. It should be noted that the embodiments in the present application and the features in the embodiments may be combined with each other without conflict.

In the embodiment, a method for controlling an indicator light is provided. FIG. 1 is a flowchart 1 of a method for controlling an indicator light according to an embodiment of the present invention. As shown in FIG. 1 , the process includes the following steps:

Step S102: Receive a multicast message indicating that the indicator light flashes synchronously according to a predetermined frequency;

Step S104: Perform synchronization flashing according to the multicast message control indicator.

Through the foregoing steps, the method for controlling the blinking of the indicator light by using the multicast message for indicating that the indicator light is synchronously blinking according to the predetermined frequency is adopted, thereby realizing the purpose of realizing the synchronous flashing of the indicator light by using the multicast message, and solving the related art As the number of indicators increases, additional hardware is required, resulting in a complicated structure and high cost, which in turn reduces the complexity and cost of the device.

There are a plurality of methods for performing the synchronous flashing according to the multicast message control indicator. In an optional embodiment, the board receiving the multicast message can use the bit bitmap control indicator to perform synchronous flashing, including the following steps: Determining a lighting parameter of the indicator light, wherein the lighting parameter comprises one or more blinking frequencies of the indicator light; converting a blinking frequency of the indicator light in the lighting parameter into a bit bitmap corresponding to the blinking frequency; according to the bit bitmap, and The multicast message control indicator flashes synchronously. Among them, different flicker frequencies can be set as needed, such as 1 Hz, 2 Hz, 5 Hz. Moreover, the use of bit maps to control the blinking of the indicator lights eliminates the need for hardware equipment, reduces system complexity, and reduces overall cost.

In the case of synchronous blinking according to the bit bitmap and the multicast message control indicator, there may be multiple control modes. In an optional embodiment, the control may be performed in the following manner: a bit bitmap corresponding to the predetermined frequency The count is cleared; the bit map control indicator after the count is cleared is used to perform the synchronous flicker of the predetermined frequency. In this way, the board that receives the multicast message can set the bit map count of the indicator light that it controls to be consistent, and achieve the effect of synchronous flicker.

The synchronizing flicker of the predetermined frequency by using the bit bitmap control indicator after the count is cleared includes: sequentially scanning the bit bitmap; and controlling the indicator according to the bit of the bit bitmap. Wherein, when performing bit bitmap scanning, the bit bitmap may be continuously scanned, or the bit bitmap may be scanned periodically. When the bit map is in binary form, 0 can be used to turn off the light, and 1 to indicate the lighting. Of course, the bit map can also be in other hexadecimal forms, and in other ways, it is turned off and lit.

FIG. 7 is a block diagram showing the structure of an indicator light control apparatus according to an embodiment of the present invention. As shown in FIG. 7, the apparatus includes a determination module 72 and a transmission module 74, which will be described below.

The determining module 72 is configured to determine an indicator light that flashes synchronously according to a predetermined frequency; the sending module 74 is connected to the determining module 72, and is configured to send a multicast message to the board, wherein the multicast message is used to indicate the determined indicator light The board control determines the indicator light to flash synchronously.

In the related art, as the number of the indicators increases, an additional hardware is required, which results in a complicated structure of the device and a high cost. In the embodiment of the present invention, a method for synchronously blinking the indicator light is provided, and the method can be utilized limited. The bit is used to control the blinking frequency of multiple indicators and achieve the effect of synchronous flicker. The main process is as follows:

First set the lighting parameters (which can include the indicator number, color, and flashing frequency); secondly, convert the blinking frequency of the indicator to the corresponding bit bitmap to be written to the shared memory; and periodically scan the bits of each indicator in the shared memory. Figure, the indicator light is turned on or off in real time to change the blinking frequency. Finally, when some indicators need to be flashed synchronously, the board of the central control point periodically issues a multicast message, and the board that receives the message sets the bit map and the count of the indicators to be the same, and achieves synchronous flashing. effect. Can be achieved through the following technical solutions:

It is possible to set the duration t _B <=1/24s for each bit, the unit blinking period T>t _B , and T can divide t _B , and the unit flashing period length N=T/t _B . It can be set to 0 to indicate that the light is off, and when it is 1, it is to be lit. According to the set flicker frequency, different binary sequences are arranged in N bits. As the number of 0,1 changes in the binary sequence increases, the blinking frequency will become faster and faster.

The bit bitmap is scanned periodically at intervals of t _B . When it is found that the current bit does not match the bit scanned at the previous time, the indicator light is turned on or off according to the value of the current bit, so that the indicator light flashes according to the set frequency.

When the card itself as the central control point is initialized successfully, the multicast message is periodically issued, and the time interval can be set to t>N*t _B . When the board that receives the multicast message is successfully initialized, the bit map of the indicator is set to be the same to achieve synchronous flashing.

Create a piece of shared memory that records the number, color, and bit map of all the lights on the board (indicated by hexadecimal numbers), and the indicator bits of the previous scan.

The board as the central control point periodically issues multicast messages, and the board that receives the message sets the bit map count of the indicator to be the same. Each board is used to control the blinking frequency of the indicator light through the selected bit map.

In the method for managing the blinking of the indicator light in the above embodiment, only one timer is used, and the bit map is used to control the blinking of multiple indicators, the flicker frequency can be adjusted, and the indicator flashes synchronously, and the number of indicators is The increase does not require additional hardware, reducing cost and system complexity.

FIG. 8 is a flowchart of a method for managing flashing of an indicator light according to an embodiment of the present invention. As shown in FIG. 8, the process includes the following steps:

Step S802, setting a lighting parameter, including a number, a color, and a blinking frequency of the indicator light. This setup command can come from the program used to monitor a device in the board or it can be a manual command input.

Step S804, converting the flicker frequency into a bit bitmap and writing to the shared memory. According to the principle of photography, it is judged by the blinking frequency of the human eye that after more than 24 pictures per second, the human eye does not feel the difference of the picture, that is, t _B <=1/24s is required. This ensures that it is not perceived by the human eye in the event of a bit error. After determining the time t _B for each bit and the unit blinking period T, the unit blinking period length N=T/t _B . Each bit can be turned off with 0, and 1 can be lit. Of course, there can be other forms of expression, such as 0 for lighting, 1 for lighting, and 0 for extinguishing in this embodiment. 1 indicates lighting to explain. According to different flicker frequencies, different bit sequence sequences are arranged in the N-bit bitmap, and bit maps corresponding to different flicker frequencies are obtained. When you need to change the flicker frequency, just modify the bit map in the shared memory.

Step S806, the timing scan indicator bit bitmap is turned on or off in real time according to the distribution of 0, 1 in the bit bitmap.

In step S808, it is judged whether the card initialization is completed, and whether the synchronization lighting interval t has arrived, and if yes, the process proceeds to step S810.

In step S810, the indicator bit bitmap and the count thereof (that is, the bit position of the current time bit bitmap) are set to be the same, and the indicator light flashes synchronously.

It should be noted that, for a certain indicator to flash synchronously, it is required to keep the indicator light on and off at each moment. Specifically, in the present invention, a bit bitmap (corresponding to a certain blinking frequency) and each are required. The bits scanned at the same time are consistent.

The above is a general description of the method provided by the embodiment of the present invention, and the method is further described below:

The method provided by the embodiment of the invention can be divided into two parts: a lighting setting process and a lighting scanning process.

FIG. 9 is a flowchart of setting a lighting device according to an embodiment of the present invention. As shown in FIG. 9, the flow includes the following steps:

Step S902, determining a correspondence relationship between the flicker frequency and the bit bitmap. According to the principle of photography, the duration of each bit t _B <=1/24s. When t _{B is} set to 40 ms, the unit blinking period T is set to 1 s, and the lighting synchronization period t is set to 2 s, the number of bits of the bit bitmap required for each blinking period is N=T/t _B =25. For each bit, 0 is used to indicate off, and 1 is illuminated. For example, for 1 Hz flicker, the first 13 positions of the 25-bit bit map are 0, and the last 12 positions are 1, the bit bitmap can be obtained as shown in FIG. 10, and FIG. 10 is a flicker frequency of 1 Hz according to an embodiment of the present invention. Bit bitmap. Similarly, according to different flicker frequencies, different bit bitmaps are arranged to obtain 2 Hz, and the bit map corresponding to the 5 Hz flicker is respectively shown in FIG. 11 and FIG. 12, wherein FIG. 11 is a flicker frequency according to an embodiment of the present invention. A bit map at 2 Hz, and FIG. 12 is a bit map at a blinking frequency of 5 Hz according to an embodiment of the present invention. Thus, in a synchronous lighting period t, the bit maps corresponding to 1 Hz, 2 Hz, and 5 Hz are represented by hexadecimal numbers as 0x1FFE000FFF, 0xFC07E07E03F, 0x6318C6318C63, respectively.

Comparing FIG. 10, FIG. 11 and FIG. 12, it can be seen that since the duration of each bit is determined, the more the number of changes of 0,1 in the bit bitmap during the unit blinking period, the more reflected to the indicator light. The more the number of changes is, the faster the blinking frequency is.

In step S904, the shared memory is turned on. The shared memory may be created by the indicator management thread in step S1302 in FIG.

In step S906, the lighting parameter is written into the shared memory mentioned in step S904. The incoming lighting parameters include the indicator number, color, and blinking frequency. When writing to the shared memory, the corresponding record is first found according to the indicator number, and the corresponding bit bitmap is written into the record according to the corresponding relationship between the blinking frequency determined by step S902 and the indicator bitmap.

FIG. 13 is a flow chart of a lighting scan according to an embodiment of the present invention. As shown in FIG. 13, the flow includes the following steps:

In step S1302, a shared memory is created. A light management thread resides on each board that creates a piece of shared memory. The shared memory holds a record for each indicator, including the indicator number, color, bit map, and the bits scanned at a previous time. As the number of indicators increases, it is convenient to add a record to the shared memory. Other threads or processes can change the blinking frequency of the indicator by modifying the bit map in the shared memory.

Step S1304, setting an indicator bitmap scanning timer. The indicator management thread can scan the bit map of all indicators every 40ms.

Step S1306, adding a synchronous lighting multicast group, for receiving a synchronous lighting multicast message of 2s at a time.

Step S1308, the message is received on the thread.

In step S1310, it is judged whether the received message is a scan bitmap timer message, if yes, the process goes to step S1312, and if no, the process goes to step S1318.

Step S1312: sequentially scan the bit bitmap of each indicator in the shared memory, compare the current time bit with the previous time bit, and if not, operate the indicator light. In this case, if the current time bit is 1, the indicator light is lit, and if it is 0, the indicator light is turned off, and the current time bit is recorded, so that it can be used in the next comparison, and then the bit count is incremented by one. .

In step S1314, it is judged whether the current board has been initialized and is located at the central control point, and the count of the bitmap reaches 50 (that is, the indicator synchronization interval of 2s is up), if yes, the process goes to step S1316, if no, the step is entered. S1308.

It should be noted that whether to issue a synchronous lighting message with an interval of 2 seconds is not based on a 2s timer, but is determined by a bitmap count of 50, mainly considering that if a timer for separately lighting is set, when located at the central control point When the position of the board changes, the synchronization lighting timer needs to be reset on the new board, which is complicated.

In step S1316, a synchronous lighting multicast message is issued.

In step S1318, it is judged whether the received message is a synchronous lighting message, and if so, the process proceeds to step S1320, and if no, the process proceeds to step S1308.

In step S1320, it is judged whether the current board is initialized or not. If yes, the process goes to step S1322, and if no, the process goes to step S1308.

In step S1322, the blinking frequency of the current board indicator is set to 1 Hz, that is, the bitmap of the indicator in the shared memory is modified to be a bitmap corresponding to 1 Hz, and the bit bitmap count is cleared. In this way, all the boards that receive the synchronous lighting message, the bit map and its count are consistent, and the effect of synchronous flicker is achieved.

FIG. 14 is a structural block diagram of an indicator flash synchronization management apparatus according to an embodiment of the present invention. As shown in FIG. 14, the apparatus includes a bit bitmap unit 142 (same as the above-described conversion unit 44) and a bitmap scanning unit 144 (same as above). The scanning sub-unit 62) and the lighting setting unit 146 will be described below.

The bit bitmap unit 142 is configured to convert the set indicator blinking frequency into a corresponding bit bitmap.

According to the principle of photography, the human eye vision residual time is 1/24 s, so the time t _B for which each bit lasts is set to be less than 1/24 s.

Set the unit blinking period T, and T can divide t _B . Then the bit bitmap length required for each blinking period is N=T/t _B .

In the N-bit bitmap, each bit is extinguished with 0 and 1 is illuminated. According to different flicker frequencies, different bit sequence sequences are arranged in the N-bit bitmap, and the indicator bit bitmaps corresponding to different flicker frequencies are obtained.

The bitmap scanning unit 144 is configured to periodically scan the indicator bitmap in the shared memory, and turn on or off the indicator.

Timing of the indicator light in the shared memory is periodically scanned at the interval t _B of each bit duration, and the scanned bit at the previous moment and the bit scanned at the current time are compared, and if the two are different, if the current bit When the bit is 0, the indicator is off, and when it is 1, the indicator is lit.

When the synchronization lighting interval t is reached, it is judged whether the current board is initialized or not, and is located at the central control point. If yes, a synchronous lighting multicast message is issued.

The card that receives the synchronization lighting message determines whether it is initialized successfully. If it succeeds, the blinking frequency is set to be consistent, and the indicator bit bitmap count is cleared.

The lighting setting unit 146 is configured to modify the bitmap of the indicator light in the shared memory according to the set blinking frequency.

A piece of shared memory is created in the board to hold the status of the indicator. When a thread or process needs to operate the indicator light, it only needs to modify the indicator bit bitmap in the shared memory according to the incoming blinking frequency.

It can be seen from the above embodiments that the method and device for managing the blinking of the indicator light of the present invention flashes the indicator light at a certain set frequency by periodically scanning the bit map of the indicator light. The multicast message is sent periodically by the card located at the central control point, and each board that receives the message sets the bit bitmap and its count to be consistent, achieving the effect of synchronous flicker.

It can be seen from the above that the method and device for synchronous flashing of the indicator light provided by the present invention are simple and easy, and the bit map is used to control the blinking of multiple indicator lights, and the flicker frequency can be adjusted. By periodically sending multicast messages, the indicator blinks synchronously. The indicator bit bitmap is saved in shared memory and can be used for multi-threaded operation indicators. When the number of indicators increases, no additional hardware is required, reducing cost and system complexity.

It will be apparent to those skilled in the art that the various modules or steps of the present invention described above can be implemented by a general-purpose computing device that can be centralized on a single computing device or distributed across multiple computing devices. Optionally, they may be implemented by program code executable by the computing device such that they may be stored in the storage device by the computing device and, in some cases, may be different from this The steps shown or described are performed sequentially, or they are separately fabricated into individual integrated circuit modules, or a plurality of modules or steps thereof are fabricated into a single integrated circuit module. Thus, the invention is not limited to any specific combination of hardware and software.
