Description
Technical Field
The invention relates to the field of scanning of electrically-adjustable antenna equipment, in particular to an antenna equipment scanning method and system.
Background
An electrically tunable antenna control system (RCS) remotely controls an electrically tunable antenna device in real time in a master-slave manner, and the master device may identify all slave devices in an unaddressed state on an interface by using a device scan message. A device scan command frame (XID) can only contain a unique matching code and mask. Only the matching secondary slave in the no address state can respond to the primary scan message. When each slave device (ALD) in the unaddressed state receives a scan command, the ALD performs bitwise and operation on its unique identification code (unique ID, UID) and a mask in a device scan command frame, and then compares the unique identification code with a matching code. If they match successfully, ALD sends a response frame to the master. After the master device issues a scan command, ALD has multiple response cases: if only one ALD satisfies matching, the main device can correctly receive the response; if no ALD can satisfy the matching, the main equipment cannot receive a response; if there are multiple ALD's that satisfy the condition, the main device is scanning collided.
When a scan collision occurs, the RCS needs to expand the scan code through the correlation strategy to narrow the scan range until a unique ALD scan is identified to obtain a matching ALD. Assuming that the number of bits left pushed by the mask is m (m is 1-4) when a collision occurs in the scanning process, when a collision occurs, the mask parameter is pushed by m bits left, m bits are added to the left side of the matching code, L is 2m new matching code strings are generated, that is, the scanning is continued after L new scanning branches are generated, and the whole searching process can be represented by one L-fork tree. Based on the scanning algorithm of the L-fork tree, the scanning range is reduced by adopting a method of increasing scanning information of the fixed position number. However, the smaller L, the greater the probability that a new match code generated at the time of a collision will match the ALD UID, and the more collision cycles; the larger L is, the smaller the probability that a new matching code generated in the collision is matched with the ALD UID is, the collision period is reduced, but the idle period is increased; the increased number of periods, whether collisions or idle periods, increases the scan time.
Therefore, the scanning algorithm based on the L-ary tree has higher complexity, needs longer scanning time and cannot effectively scan out the needed equipment in time.

Example 2
With the development of the times and the progress of the society, the demand of people on wireless communication and the requirement of network quality are increasing day by day, and the problem of wireless network optimization becomes more and more important. Network operators are also more concerned about improvements and improvements in network quality. Network optimization is the most direct and effective method for improving the quality of a mobile network and is also a key technology in network communication, wherein optimization of base station antennas is the main method for network optimization. In the network optimization process, the implementation difficulty is high due to the fact that the height of the antenna is changed, and therefore the coverage area of a small area is often changed by adjusting the inclination angle of the antenna. By selecting an appropriate tilt angle, an appropriate coverage area can be obtained, interference can be minimized, and thus an optimal signal strength can be obtained.
The antenna is divided into an electric tuning antenna and a non-electric tuning antenna according to whether the inclination angle of the antenna is adjustable. The non-electric tuning antenna is a traditional mechanical antenna, the antenna cannot be adjusted in severe weather, the problem of 'volume breathing' cannot be solved in time, and the whole network optimization cannot be performed in a short time. The electric tuning antenna can realize remote adjustment, has high adjustment and optimization efficiency and strong real-time performance, and the actual coverage range is closer to the network prediction planning, so that the coverage is more precise. The AISG protocol is a communication specification between an antenna intelligent device and a base station jointly established by mobile communication system manufacturers and microwave antenna related manufacturers which are mainstream in the world. Therefore, the compatibility and interoperability of the electric tilt antenna equipment of different manufacturers are realized. The current common scheme is to use an antenna attitude tester to update the latest data of a base station antenna in a system platform to the antenna attitude tester, and the antenna attitude tester is not really remote control. In the system, a computer end is adopted for remote control, a main station sends a command to a remote control unit, and the remote control unit realizes real remote control through a control antenna. According to the AISG protocol and 3GPP specifications, the master station is to implement control of the remote control units (slaves) by first obtaining all the slave basic information. And the scanning completes the searching of the slave devices hung on the network and the acquisition of the device information. After the scanning is completed, the master station can perform other command operations on the slave device.
In the AISG protocol, a scanning frame format is specified, but a detailed description is not given to a specific implementation manner of scanning, and each manufacturer needs to design a corresponding scanning algorithm by himself during development.
The scan frame sent by the master device includes the match code and mask compared to the UID of the slave device. And the mask and the slave equipment serial number are subjected to AND operation, and the operation result is compared with the matching string code. After the slave device sends a scanning frame, if a plurality of slave devices respond simultaneously, the slave devices share one 485 bus simultaneously, so that signal superposition occurs and collision occurs, and the master device receives an error response frame and needs to continue scanning downwards; if only one electric tilt antenna device is matched, the master device receives a normal XID response frame, and marks that one electric tilt antenna device is successfully scanned. After a device is successfully scanned, the host assigns a temporary HDLC address to the device so that the device does not respond to the subsequent scanning frame; if no electric tilt antenna device is matched, the main device does not receive any response within the designated time. Assuming that a period from the time when the master device broadcasts a scanning frame to the time when the slave device receives feedback is called a scanning period, the scanning period is classified into the following 3 types according to possible response situations:
and (3) collision period: and 2 or more than 2 slave devices respond simultaneously, the response signals collide, and the master device receives the error frame and needs to further scan.
An idle period: there is no response.
Readable period: only one slave device responds, and the master device receives a correct response frame, so that the basic information of the slave device is successfully acquired.
In order to solve the scanning collision and shorten the scanning time, the present embodiment performs bit-by-bit scanning on a given sequence number to determine whether the sequence number matches with a reference sequence. The method of identifying each different device from the plurality of online device lists by screening. Since the probability that the same character appears at the corresponding position from right to left of the manufacturer serial number increases in sequence, the 0 th bit to the nth bit are scanned in sequence from right to left. The method provided by the embodiment comprises the following steps:
step 201, determining the maximum scanning layer number and the maximum scanning precision according to the number of bits of the serial number of the antenna device, where the number of bits n of the serial number, the maximum scanning layer number depth, and the maximum scanning precision grade satisfy the following formulas: a × grade × depth ═ n (1); where a denotes the number of bits of one mask advance when the grade ═ 1.
The maximum scanning layer number can be determined by adopting the following method:
constraint 1: the proportion of equipment which can be distinguished by traversing one precision is more than or equal to ninety percent;
constraint 2: the time it takes for the device to complete a single layer count is minimized.
The maximum number of scanning layers depth, i.e. the scanning depth, can be obtained by performing optimization processing according to the constraint conditions, and therefore, the determination of the scanning depth is determined by the time consumed by performing one-time comparison by the minimum comparison unit of the device and the characteristics of the serial number itself. Then, the maximum scanning accuracy, which is the preset value in embodiment 1, is calculated according to formula (1). Wherein a can be 2 or 4, and when a is 2, the precision is higher.
In determining the number of bits of the serial number of the antenna device, the complete serial number is usually used, but when special cases are encountered, the following method may be adopted:
a. comparing the serial numbers of the antenna devices, and determining the number of continuous bytes of the serial numbers which are completely the same from left to right and the number of bytes which need to be scanned; and averagely dividing the number of bytes needing to be scanned into a plurality of layers. For example, the sequence number of eighteen bits is the same as the first eight bits, so when the scanning layer number is generated, the first eight bits can be skipped over, and the latter ten bits are equally divided into a plurality of depth segments; second, the division of the number of layers, in relation to the efficiency of the comparison unit, is appropriate if more than ninety percent of the devices can be distinguished with twelve accuracies per depth.
b. And (3) carrying out independent optimization aiming at special equipment, such as counting the similarity of the sequence number field, and skipping certain bits when scanning the field with high similarity.
Step 202, dividing the serial number of the antenna device into n layers according to the maximum scanning layer number, wherein the number of bits of the serial number included in each layer is the same, as shown in fig. 2.
And step 203, starting from the first layer of the sequence number, constructing a first group of nodes according to the scanning precision of 1, and adding the first group of nodes into a scanning queue.
And step 204, taking out the head element from the scanning queue, and constructing scanning information according to the head element.
Step 205, sending out the scanning information in a broadcasting mode.
Step 206, acquiring response information of the scanning information.
Step 207, when the response information is formed by matching information of a plurality of antenna devices, judging whether the current scanning precision is greater than the maximum scanning precision, if not, increasing the number of bits of the scanning information, namely adding 1 to the original scanning precision to construct new scanning information; if so, the scanning layer number is switched, namely, the scanning depth is increased by one layer, and new scanning information is constructed when the scanning precision is 1.
The host device finds a plurality of response frames in the buffer stack, which indicates that UIDs of a plurality of ALD are consistent with the matching code string of the scanning frame, the scanning precision needs to be increased, based on the scanning precision, a next layer node is constructed and added into a newly constructed lower layer queue, based on the scanning precision, a higher-precision lower layer scanning frame is started, and the devices are distinguished. If the scanning precision reaches the current maximum precision value (Grade-max) and the collision response is still received, the scanning depth is insufficient under the supported scanning precision, so that the scanning depth is increased, and the scanning is started from the lowest precision to the deeper level of the deep submergence entry sequence.
And step 208, when the response information is formed by matching information of one antenna device, determining the identification information of the antenna device sending the response information according to the response information.
And the master device receives a response frame with correct CRC in a buffer stack, successfully scans an ALD (atomic layer deposition), extracts the frame from the stack, acquires basic information of the device, including UID (user identifier), device type and the like, constructs an address allocation XID frame according to the UID of the device, sends the address allocation XID frame to the device, and allocates an unallocated address in an address base to the device so as to prevent the device from responding to the broadcast XID frame again. For nodes to be readable, the scan need not increase in precision and depth.
In step 209, when no response message is received, the process returns to step 204.
In the frame receiving period of the main device, if the stack has no normal frame stored, it shows that the UID of any ALD device does not conform to the matching code string of the scanning frame, and then a node element is taken down from the node queue of the layer for scanning. For the idle node elements, the scanning is continued without increasing the precision and the depth of the scanning.
Assuming that there are m ALD devices to be scanned on the network, the readable period, the idle period and the collision period are included in one complete scanning period, and the consumption time of the three periods is assumed to be equal, so that one complete scanning time is the sum of the three periods. Let the parameter L denote the idle period, R the readable period and C the collision period. According to the method of the present invention, the expectation of the idle period, the readable period, and the collision period in the scan can be expressed as:
assuming that the expectation of idle, readable and collision cycles at depth d can be expressed as:
L(m,d)＝4grade(1-4-grade)m
R(m,d)＝m(1-4-grade)m-1
C(m,d)＝4grade-L(m,d)-R(m,d)
wherein grade is 2 n/d.
The total number of collision cycles and the total number of idle cycles in a complete scanning cycle are respectively the sum of collision cycles and the sum of idle cycles in each depth of deep-diving scanning, so that:
the embodiment divides the long serial number into a plurality of different depths and carries out multi-fork tree scanning by taking the precision as an adjusting point; according to the length of the scanning sequence, the scanning depth and precision are dynamically adjusted, the algorithm complexity is reduced, and the scanning time is reduced; the method has wide adaptability, and can select proper maximum scanning precision for sequences with different lengths and different characteristics so as to further improve the scanning efficiency of the algorithm, and is easy to realize and operate.
