Description

Background Art

[0002] At present, according to national standards, high-rise buildings must be equipped with aviation obstruction lights so that passing aircraft can see the "outline" of the object or group of objects from all aspects, and cooperate with the synchronous flashing of the aviation obstruction lights to achieve an obvious warning effect.

[0003] Aviation obstruction lights usually provide light signals in the form of flashing. When multiple lights are installed around a building, the flashing sequence is irregular. It is necessary to provide each light with a synchronization signal to keep the flashing in step, that is, when one light is on, the others are also on, and when one light is off, the others are also off. The technical standard requires that the flashing start time is 00:00:00 UTC, and the flashing timing error between the two lights is less than 50ms. At present, the commonly used technical solutions include:

[0004] (1) The main light is connected to the backup light. A signal line is connected from the main light to control the backup light so that the two can flash together. However, when the main light fails, the signal is lost and the backup light cannot work normally.

[0005] (2) Centralized control by control box, which ensures the synchronous flashing of each lamp by switching on and off the circuit in the control box. However, the centralized control range of the control box is limited and can usually only support 4-8 lamps.

[0006] (3) Install GPS modules on each aviation obstruction light to synchronize the lights. Install GPS modules on each aviation obstruction light, and the timing accuracy can reach ns, so the synchronization can be very good. However, the lights are usually equipped with light sensors. When the light values ​​of the lights are different, their on and off states will also be inconsistent, thus affecting the synchronous flashing.

[0007] Therefore, the present invention provides a system, method, device and storage medium for synchronous flashing of aviation obstruction lights. Summary of the invention

[0056] Figure 1 Schematic diagram of the structure of the synchronous flashing system of aviation obstruction lights of the present invention. Figure 1As shown, the aviation obstruction light synchronous flashing system of the present invention is characterized by comprising: a main control module 1 and a plurality of control panels 21, 22, 23, the main control module 1 is serially connected to a plurality of control panels 21, 22, 23 in sequence through a data bus, and each control panel 21, 22, 23 is respectively connected to a plurality of aviation obstruction lights in parallel. The main control module 1 comprises a GPS module 11 and a light sensing module 12, the GPS module 11 generates a GPS data packet including at least a pulse signal, the light sensing module 12 generates a light intensity value, the main control module 1 establishes a synchronous data packet with the GPS data packet and the light intensity value corresponding to the timing of the GPS data packet, and transmits the synchronous data packet to the control panels 21, 22, 23 step by step. The control panels 21, 22, 23 of each level shall compensate for the transmission time based on the serial order to obtain the synchronization time of the current level, and shall synchronously light up the corresponding aviation obstruction lights based at least on the synchronization time and the light intensity value. The present invention provides a method based on RS485 communication to centrally control the synchronization of aviation obstruction lights on buildings. All aviation obstruction lights, controllers, GPS modules, and light-sensitive sensors on the building are collectively referred to as a system. In order to achieve synchronous flashing of each aviation obstruction light in the system, it is necessary to provide them with a stable synchronization signal. The communication method adopts RS485 to form a multi-level discrete control method. In the control block diagram of the aviation obstruction light synchronization system, the photosensitive sensor control board is the first level when viewed vertically, the control board 21 is connected to the control board 21 via RS485 serially as the second level, the control board 22 is connected to the control board 22 as the third level, and the control board 23 is connected to the control board 23 as the fourth level; N aviation obstruction lights are connected in parallel in each level; the synchronization signal is initiated by the photosensitive sensor to each control board through the protocol, and is forwarded by the control board to the lamps on the same floor; each control board on each floor has one communication input and one communication output; the positional relationship of each control board is equivalent according to the protocol function and can be replaced with each other; the output end controls the N groups of lights on this floor; each group of lights is connected in parallel through the communication protocol, so each light on the same floor receives the same data; the timing deviation between multi-level communications is eliminated through a specific transmission protocol method to achieve synchronous flashing of the lamps.

[0057] Among them, the data bus is RS485 bus. RS485 is a standard for multi-point communication with two-wire, half-duplex, balanced transmission lines and electrical characteristics belonging to the physical layer of the OSI model. It is a standard jointly issued by the Telecommunications Industry Association (TIA) and the Electronics Industry Alliance (EIA). A digital communication network that implements this standard can communicate efficiently over long distances in an environment with electronic noise. Under the configuration of a linear multi-point bus, there can be multiple receivers on a network. Therefore, it is suitable for industrial environments. PPS: Pulse Per Second is a pulse per second signal generated by the GPS receiver module (GPS Receiver). Its function is to indicate the time interval of the whole second, and to mark the specific moment corresponding to the UTC (Coordinated Universal Time) time given by GPS through the rising edge of PPS. The accuracy of the indicated whole second time can reach tens of nanoseconds, without cumulative error. The PPS generated every second and the whole second moment it gives can be used for accurate frequency modulation of the crystal oscillator - clock synchronization. UTC is Coordinated Universal Time, also known as World Unified Time, World Standard Time, and International Coordinated Time. Coordinated Universal Time is a time measurement system based on the length of the atomic second and is as close to the universal time as possible.

[0058] The failure of any aviation obstruction light in the present invention will not cause signal loss, and other lamps can still work normally; more than 8 lamps can be mounted on any control panel in the present invention. The total system can carry more than 32 lamps. In the present invention, light sensing and the global navigation satellite system GNSS (Global Navigation Satellite System) are integrated into a set of light-sensitive sensor control panels to ensure the consistency of light sensing and synchronization signal data timing in the entire system. GNSS is a general term for all navigation and positioning satellites, that is, the Global Navigation Satellite System (Global Navigation Satellite System). Any system that can achieve positioning by capturing and tracking its satellite signals can be included in the scope of the GNSS system, including the United States' GPS, China's BDS, Russia's GLONASS and Europe's GALILEO.

[0059] In a preferred embodiment, each level of control board 21, 22, 23 performs single-level transmission delay Δtd compensation on the pulse signal in the received synchronization data packet, and transmits the compensated GPS data packet to the next level of control board 21, 22, 23, but is not limited to this.

[0060] In a preferred embodiment, the single-stage transmission delay Δtd is:

[0061] Δtd=LEN*(DATL / N_BPS).

[0062] Wherein, LEN is the data byte length of the GPS data packet, DATL is the unit data placeholder, and N_BPS is the communication baud rate, but is not limited to this.

[0063] In a preferred embodiment, the control boards 21, 22, 23 at each level also compensate the pulse signal for the inter-board transmission delay Δtp, and transmit the compensated GPS data packet to the next control board 21, 22, 23. The inter-board transmission delay Δtp is:

[0064] Δtp=n1*(Ncpu+1) / Hcpu.

[0065] Among them, n1 is the number of program processing instructions, Hcpu is the chip main frequency of the control board 21, 22, 23, and Ncpu is the clock period of the pulse signal, but it is not limited to this.

[0066] In a preferred embodiment, the main control module 1 performs delay compensation Δtpp between the pulse signal and the real time, and transmits the compensated GPS data packet to the next control board 21, 22, 23, Δtpp<100ns, but not limited thereto.

[0067] In a preferred embodiment, the control boards 21, 22, and 23 at each level perform a delay compensation Δtpl on the pulse signal for lighting the lamp, and synchronously transmit the compensated GPS data packet to the corresponding aviation obstruction light. The delay compensation Δtpl for lighting the lamp is:

[0068] Δtpl=n2 / Hcpu.

[0069] Among them, n2 is the instruction cycle for lighting the lamp, and Hcpu is the chip main frequency of the control board 21, 22, and 23.

[0070] In a preferred embodiment, the lighting time of the aviation obstruction light is set to the rising edge of the received pulse signal, and it is turned off after lasting for a preset window, waiting for the next pulse signal cycle to light up again, but not limited to this.

[0071] Figure 2 This is a timing diagram of the PPS signal and the GNSS signal when the aviation obstruction light synchronous flashing system of the present invention is implemented. Figure 2 As shown, the synchronization signal in the present invention is derived from the PPS second pulse signal of the GNSS module, and the synchronization time and light intensity value are transmitted through the RS485 communication method; the timing of the PPS second pulse signal and the GNSS data message is as shown in the figure below, wherein the biggest feature of the PPS (Pulse Per Second) second pulse signal is that it is timed by satellite, with an accuracy of up to 100ns and can be output continuously; the GNNS data message contains UTC time, longitude and latitude, satellite parameters, etc.

[0072] Figure 3 This is a timing diagram of the lighting time and PPS signal of the aviation obstruction light synchronous flashing system of the present invention. Figure 3 As shown, the lighting time of all lamps is set to the rising edge of the PPS signal, and then they are turned off after a period of time; they wait for the next PPS signal cycle to light up again; the flicker error of the entire system will approach 0ms.

[0073] Figure 4 This is a synchronous timing error diagram of the aviation obstruction light synchronous flashing system of the present invention. Figure 4 As shown in the figure, the time synchronization process is as follows: in the aviation obstruction light synchronization system block diagram, the light-sensitive sensor module obtains the light intensity value and the GNSS time, longitude and latitude, and PPS signal quantity, and transmits it to the next-level controller or aviation obstruction light according to the specified communication protocol. During the transmission process, certain delays and errors will be generated, resulting in inconsistency between the flashing point of the lamp and the UTC time. Therefore, it is important to analyze the timing error in this process.

[0074] Synchronous timing error such as Figure 3 , the error mainly comes from three parts:

[0075] (1) The difference between the time data from the light-sensitive sensor and the actual UTC time.

[0076] The accuracy error between the PPS signal and the true UTC time is Δtpp, Δtpp<100ns.

[0077] (2) Timing delay caused by inter-board transmission.

[0078] In the light sensitive sensor control board, the PPS signal generates an interrupt, triggering the interrupt processing program of the controller, and then sends it after processing and analysis; during this period, a data processing delay is generated, and the interrupt waiting delay is Ncpu clock cycles. The interrupt vector controller lasts for one clock cycle, and the main frequency is Hcpu, so the interrupt delay is (Ncpu+1) / Hcpu=0.18us; the program processing instructions are n1, and the delay is Δtp;

[0079] Δtp=n1*(Ncpu+1) / Hcpu;

[0080] In this embodiment, the interrupt waiting clock cycle is 12, the main frequency Hcpu is 72Mhz, and the program processing instruction n1 is 20, so Δtp=20*13 / 72Mhz=0.46us;

[0081] The control board has two RS485 ports, one master and one slave. After the master port receives the communication data, the maximum difference between the time in the data and the actual UTC time is Δtd, which is the data communication delay time. When the communication baud rate is N_BPS and the data byte length is LEN, the basic data format is 1 idle bit, including the start bit, stop bit, check bit, and data 8 bits, a total of 11 bits are recorded as DATL. The single-stage transmission delay time is:

[0082] Δtd=LEN*(DATL / N_BPS);

[0083] For example, in normal use, the data byte length LEN is 36, the communication baud rate N_BPS is 9600bps, and the unit data bit DATL is 11b. Substitute it into the above formula Δtd=36*(11 / 9600)=41ms.

[0084] (3) The processing delay from when the lamp receives the message to when it lights up.

[0085] After receiving the message, the lamp needs to parse the communication protocol and control the lamp to be on or off according to the time. The time consumed in the process is n2 instruction cycles; Δtpl = n2 / Hcpu;

[0086] In this embodiment, n2 is 100, Δtpl=100 / 72Mhz=1.4uS.

[0087] In the first lighting timing cycle, the maximum accumulated time difference is Tmax; in the second lighting timing cycle, the previous action is repeated so Tmax remains unchanged and no continuous cumulative effect is produced.

[0088] Tmax=Δtpp+Δtp+4*Δtd+Δtl;

[0089] In the actual test, Tmax = 100ns + 0.46us + 4*41ms + 1.4us = 164.00196ms;

[0090] In addition, it can be seen from the above analysis and calculation that the synchronization timing error is mainly the Δtd caused by the transmission delay. Eliminating such errors can greatly optimize the time accuracy of each node in the system;

[0091] Protocol Format

[0092]

[0093] Usually in network systems, due to regional differences, network congestion, server performance differences and other reasons, the delay time of network services is not a fixed value; in the present invention, the format of the data content transmitted is customized and the transmission rate is fixed, so its delay is a relatively fixed and calculable value; the initiation of data transmission is determined by the rising edge of the PPS second pulse signal, and the transmission protocol includes UTC time, data byte number field, and synchronization deviation field; when the controller receives a set of data, its system time is the time in the data plus the synchronization deviation field value, and its deviation field value calculation formula is Δtd, then the updated time of this controller and the actual UTC deviation value can offset each other, and at the same time, the UTC time remains unchanged when transmitted to the next level program, and the delay time Δtd caused by increasing the data length in the synchronization deviation field, so that the next level receiving end can still maintain the associated synchronization with the PPS signal; the maximum deviation is 1 byte receiving time according to the Δtd formula is 1.14ms.

[0094] Figure 5 This is a diagram of the inter-stage timing error when the aviation obstruction light synchronous flashing system of the present invention is implemented. Figure 5 As shown in the figure, when the first-level lamp (the lamp connected to the control board 21) receives the data, the current time is updated to T0+Δtd given by the superior, and the difference between its time and the actual UTC time is very close; the second-level lamp (the lamp connected to the control board 22) receives the data and the transmission compensation time is 2*Δtd. When it receives the data, the time will become T0+2*Δtd, and the actual time is also close to the UTC time.

[0095] Figure 6 This is a flashing effect diagram when the aviation obstruction light synchronous flashing system of the present invention is implemented. Figure 6 As shown, each aviation obstruction light can flash synchronously when the final flashing effect of the lamp is achieved. The time in the lamp is compensated by protocol synchronization, so that its system time and the actual UTC time are close, eliminating the time error caused by data transmission in the above analysis. By observing and counting the voltage of the lamp flashing, the time difference between the lamp and the PPS signal is less than 10ms; after receiving the protocol data, each level of controller in the system compensates for a certain transmission time so that the next level can obtain the accurate UTC time through compensation, so that the time of the entire system can be accurately unified; in order to improve system efficiency and reduce the communication frequency, it is sent every 6s. During the asynchronous period, the time runs through the internal clock of the controller, and the accuracy of the crystal oscillator is 10 (ppm); the time error generated during operation is: Tr = 10ppm × 6s = 60us; far less than the ms level required by the design; if the pps signal is lost, the system can continue to run synchronously for: Tc = 50ms / 10ppm = 5000s; that is, 1.38 hours, which shows that the synchronization effect has reached the expected effect.

[0096] Figure 7 The flowchart of the method for using the synchronous flashing of the aviation obstruction lights of the present invention is as follows. Figure 7 As shown, the method for using the synchronous flashing of aviation obstruction lights of the present invention adopts the above-mentioned synchronous flashing system of aviation obstruction lights, and comprises the following steps:

[0097] S110, the GPS module generates a GPS data packet including at least a pulse signal, and the light sensing module generates a light intensity value.

[0098] S120, the main control module creates a synchronous data packet with the GPS data packet and the light intensity value corresponding to the timing of the GPS data packet, and transmits the synchronous data packet to the control board step by step.

[0099] S130, the control board of each level needs to compensate for the transmission time when performing in a serial order to obtain the synchronization time of this level.

[0100] S140. The control panel lights up the corresponding aviation obstruction lights based at least on the synchronization time and the light intensity value.

[0101] The aviation obstruction light synchronous flashing method of the present invention can realize the synchronous lighting of multi-stage connected aviation obstruction lights, and after the PPS pulse signal is lost, the aviation obstruction light system can still maintain the synchronization characteristics for a period of time.

[0102] The embodiment of the present invention further provides an aviation obstruction light synchronous flashing device, comprising a processor and a memory, wherein executable instructions of the processor are stored, wherein the processor is configured to execute the steps of the method for using the aviation obstruction light synchronous flashing by executing the executable instructions.
