The method for lighting the urban lamp comprises the following steps: the controller is to signal relay output high level, lets signal relay's normally open contact one, normally open contact two and normally open contact three closed, just can switch on this city lamps and lanterns and light, and the controller is to signal relay output low level, lets signal relay's normally open contact one, normally open contact two and the three disconnection of normally open contact, just can let this city lamps and lanterns extinguish. The method for obtaining the lighting time and the extinguishing time of each city lamp by the controller according to the input advance or delay of the sunrise time and the advance or delay of the sunset time corresponding to each city lamp can be as follows:
according to the advance or delay amount of the sunrise time corresponding to each city lamp, subtracting the advance or adding the delay amount of the sunrise time corresponding to the city lamp preset in the controller respectively, and taking the result as the corresponding turning-off time of the city lamp;
according to the advance or delay amount of the sunset time corresponding to each city lamp, the advance or the delay amount is subtracted from or added to the sunset time corresponding to the city lamp preset in the controller, and the result is used as the corresponding lighting time of the city lamp.
Further, the step 1 specifically includes:
controller and remote control platform, the controller is towards the information of remote control platform transmission city lamps and lanterns, specifically as follows:
step 1-1: a timing link detection message mode is additionally arranged in the controller to detect the link condition of the mobile communication network between the controller and the remote control platform;
step 1-2: the controller transmits the acquired information of the urban lamps to a remote control platform in real time, and a cache is synchronously constructed in the controller to store information messages of the transmitted information of the urban lamps;
step 1-3: the remote control platform writes the smoothly received information of the urban lamps into an information table according to the sequence and transmits back a feedback message;
step 1-4: the controller determines whether the mobile communication network is abnormal or not according to the received feedback message condition;
step 1-5: and searching the information message of the information of the urban lamps which is not transmitted when the mobile communication network is abnormal in the cache, and transmitting the information message again to achieve the reduction type retransmission. The sequence is the sequence in which the controller acquires the information of the urban lamps.
In the application, the controller runs a concurrent program for acquiring the information of the urban lamps, and transmits the current information of the urban lamps after the information of the urban lamps is acquired; because the information of the urban lamps is acquired according to the sequence, correspondingly, the information transmission of the urban lamps is also performed according to the sequence, however, the time intervals among all the stages are different; to ensure that the information of important urban lamps is not lost, the controller needs to acquire the feedback of the remote control platform; in addition, the high speed required by the instant transmission of the information of the urban lamps is also involved, and when the feedback of the information message of the information of the previous urban lamp by the remote control platform is not obtained, the controller often needs to transmit the information message of the information of the other urban lamps; however, no matter whether the information message of the information of another city lamp exists or not, the controller sets the constraint of receiving overdue, that is, if the controller does not acquire the feedback message of the remote control platform in the set overdue time period, it can determine that the information message of the information of the city lamp is lost.
If the mobile communication network link is smooth, the controller often obtains a plurality of feedback messages at one time after transmitting information messages of information of other urban lamps, which represents that the remote control platform smoothly obtains the information messages of the information of the urban lamps transmitted at the previous time.
If the mobile communication network link is not smooth, the controller often does not obtain one feedback message after continuously transmitting the information messages of the information of the urban lamps, or only obtains less than X feedback messages after continuously transmitting the information messages of the information of the X urban lamps, and at the moment, the controller can judge that the current mobile communication network has link abnormality.
The abnormal condition is that a link of a mobile communication network has an obstacle during the period of transmitting the information of the instant city lamps by the controller, so that the information of the city lamps transmitted by the controller is not obtained by the remote control platform, and the remote control platform can not transmit a feedback message to the controller; another abnormal situation is that the remote control platform obtains the information of the urban lighting fixture transmitted by the controller, and the link of the mobile communication network has an obstacle when performing feedback, so that the controller does not obtain the feedback message fed back by the remote control platform in a set time period.
Therefore, to ensure that the information of the urban lamps is completely received by the remote control platform, the controller retrieves and transmits the information message of the information of the urban lamps, which does not obtain the feedback message, in the cache, and executes the operation of reducing retransmission.
The timed link detection message mode comprises: the controller starts a concurrence program for transmitting the link detection message to reach each time distance y1(s), the controller transmits the link detection message to the remote control platform, the remote control platform waits for the feedback message determined by negotiation in advance, if the feedback message is obtained in the set overdue time period, the smoothness of the current mobile communication network can be determined to be good, and the software of the current remote control platform operates without errors; if the feedback message is not obtained in the set overdue time period, the mobile communication network is represented to have obstacles; here, the expiration period can be set according to a specific situation.
The cache is U ═ z1, z2 … zX, z1 is a head component of the cache, and the head component is an information message of the information of the urban lamp written into the cache firstly; zX is the end component of the cache, which is the information message of the last written city light fixture information, and each cache component increases the time point when the information message of the city light fixture information is transmitted besides the effective information of the information message of the city light fixture (the effective information is the binary code of the information of the city light fixture); to ensure that each component zv in the cache is simple and practical in execution, the capacity of each component of the cache is set to be the highest character quantity of an information message for transmitting the information of the urban lamp, the number of the synchronous cached components is initialized to be X, X is the number of the information messages of the information of the urban lamp, and v is a natural number not higher than X; after the controller returns the information messages of the information of the instant city lamps, the transmitted information messages of the city lamps are added to the tail end of the cache U, the cache U is filled after the controller transmits the information messages of the information of the X city lamps, the information messages of the information of the subsequent city lamps are written into the cache in sequence through the tail end of the cache, and the information messages of the information of the city lamps at the head of the cache are read out from the cache in sequence.
The method of re-transmitting includes: when a link of a mobile communication network has a fault, the controller does not obtain a feedback message fed back by the remote control platform, then the controller searches an information message of the information of the urban lamp to be transmitted again in the cache U, and the searched search word is the time point when the information message of the information of the urban lamp is transmitted; if a plurality of information messages which are not fed back exist, the controller executes a plurality of retrieval and retransmission processes in the cache U; and the information message of the information of the urban lamp transmitted by the retransmitted process is not written into the cache.
And during the period of retransmitting the information message of the information of the original retransmitted urban lamp, when the controller needs to transmit the information message of the information of the other urban lamp, the controller executes the information message transmission of the information of the other urban lamp after the current information message retransmission of the urban lamp is achieved, and adds the information message of the information of the other urban lamp to the tail end of the cache.
The number of the cached component elements is provided with a maneuvering change mode, under the maneuvering change mode, the number of the cached component elements, y3, y1, y2, y1 is the timing distance for the controller to transmit the link detection message to the remote control platform, and y1 is a constant; y2 is the minimum time interval for transmitting the information message of the information of the current city lamps; thus, the lower y2 is, the higher y3 is, the more the cache of the number of elements consumes the more software and hardware, and the longer the cache is; however, too high value of y2 may make y3 too low, and too low number of elements in the cache often cannot meet the requirement that information messages of information of the whole transmitted city lamp are written into the cache for temporary storage, so that y2 is set as the arithmetic mean of the transmission time intervals between the information messages of the information of the past W-loop city lamp of the controller, where W is a positive integer higher than one; w returns and transmits the time interval quantity to store in the temporary storage area, every time interval of transmission formed newly is written into the temporary storage area to upgrade the most first time interval quantity information, after the temporary storage area totals to W times the time interval, carry out y3 ═ y1 ÷ y2, obtain the quantity of this y3 and serve as the component element number of the buffer memory, correspondingly, also change the information message of the information of the urban lamps and lanterns stored in the buffer memory. The amount of W is often a positive integer from three to five.
By applying the maneuvering change mode of the cache in the application, the setting of the number of the cached group elements is more in line with the real condition of information message transmission of the information of the urban lamp by the current controller: if the time interval is high, the number of the cached group elements is reduced to save the use degree of software and hardware; and if the time interval is low, increasing the number of the cached group elements to maintain the temporary storage requirement of the information message of the information of the urban lamp with higher quantity.
The method for changing the information message of the information of the urban lamps stored in the cache comprises the following steps:
executing y 3-y 1 ÷ y2, obtaining the amount of y3 as the number of buffered elements, and when the number of buffered elements is higher than that of the buffered elements, connecting the higher number of elements to the head of the buffered element and setting another buffered head element; just like y3 is increased by B compared with the number of elements in the previous buffer, B is a positive integer higher than one, then the increased B elements are connected to the head of the previous buffer, and the head elements of the other buffer are set, finally the number of elements in the extended buffer is X + B, and when the number of elements in the buffer is lower than the number of elements in the previous buffer, the lower part of the number of elements is cut off through the head of the previous buffer, and the head elements of the other buffer are set. As y3, the number of elements in the previous buffer is reduced by B, B is a positive integer higher than one, B elements are cut off from the head of the previous buffer, and another buffer head element is set, and finally the number of elements in the reduced buffer is X-B.
In summary, the above method specifically includes:
step A-1: the controller constructs a mobile communication network link between the controller and the remote control platform and clears the cache;
step A-2: if the city lamp information is not the information message transmission of the information of other city lamps, if the city lamp information is the information message transmission of the information of the current city lamp, the current city lamp information is transmitted and the step A-3 is carried out, and if the city lamp information is not the information message transmission of the information of the current city lamp, the step A-6 is carried out;
step A-3: adding the information message of the transmitted information of the current city lamp into the tail end of a cache, advancing the cache in sequence, shifting the information message of the information of the city lamp at the head of the cache out of the cache, and registering the time interval of the previous information message of the information of the transmitted city lamp;
step A-4: determining whether the number of the registered time intervals is equal to W, if so, turning to the step A-5 for execution, and if not, turning to the step A-6 for execution;
