Description

Background

The indoor distribution system is an indoor distribution system, mainly introduces base station signals indoors, solves signal extension and coverage, improves indoor communication quality, and is an indispensable component of mobile communication in a metropolis.

An indoor subsystem generally comprises a host (near-end unit) and a slave (far-end unit), wherein the host mainly has the function of accessing signals from a base station, and is also called an access end; the slave is mainly responsible for signal zooming and covering; the master and the slaves are connected through cables, and one master is generally connected with and communicates with dozens of slaves.

The indoor distribution system comprises the processes of equipment site selection, cable arrangement, equipment installation, equipment power-on station opening, equipment performance debugging, delivery and use and the like from planning to opening and using, wherein a main machine is mainly installed in a relatively open place such as a weak current well, and a slave machine is generally installed in a relatively narrow place such as an indoor ceiling.

In order to monitor the running state of each device in the indoor distribution system in real time in the monitoring center, the indoor distribution system devices are visually displayed on a monitoring interface in a connection topological graph mode, and the monitoring center needs to keep communication with each device in the time-sharing system; or the monitoring center keeps communication with the host, the host keeps communication with the slave, and the state information of the slave is transmitted to the monitoring center through the host. In order to ensure normal and smooth communication, the devices in the mobile communication protocol room subsystem must have a unique number (one byte) in their system (a master and its connected slaves constitute a system) for distinguishing each other, wherein the master number is fixedly allocated to 0x00, the slave number is allocatable to [0x01,0xFE ], and in order to facilitate mass production of the devices, the device numbers of all slave devices at the time of factory shipment are identically configured to 0xFF. The device number of the slave must be reconfigured in the project before the device is turned on.

The traditional method for configuring the slave equipment numbers in engineering is that all equipment is electrified after being installed and detected to be correct, then the installed slave equipment is found out one by one according to a drawing, and the equipment numbers are redistributed to the slave equipment through a serial port or a network port.

This operation causes the following problems:

(1) Communication interfaces are required to be reserved in the slave equipment, so that the dustproof and waterproof performance of the equipment is reduced;

(2) The slave machine is arranged in narrow places such as a ceiling, the operation space is extremely limited, the operation is extremely difficult, sometimes even the ceiling or other equipment needs to be removed to finish the operation, and the hidden cost of the equipment is increased;

(3) The same equipment needs to be operated at least twice (installation and numbering configuration), so that the installation cost is increased;

(4) The risk resistance of the equipment is reduced, the configured equipment number must be ensured to be correctly stored and read, and if the storage medium of the equipment is damaged due to external factors, the equipment cannot be correctly monitored, so that the equipment is out of service.

Therefore, how to improve the equipment installation opening efficiency of the indoor distribution system and reduce the equipment installation cost and the later maintenance cost is a technical problem which needs to be solved urgently.

The above is only for the purpose of assisting understanding of the technical aspects of the present invention, and does not represent an admission that the above is prior art.

An embodiment of the invention provides an automatic topology identification method for indoor distribution system equipment, and referring to fig. 3, fig. 3 is a schematic flow diagram of a first embodiment of the automatic topology identification method for indoor distribution system equipment.

In this embodiment, the method for automatically identifying a topology of indoor distribution system equipment, which is used at a host side, includes the following steps:

and S100, acquiring polling time slot information, and polling a plurality of slave terminals based on polling serial numbers.

Specifically, before the host performs polling, it needs to acquire polling slot information, and then perform a polling process on a plurality of slave terminals according to polling sequence numbers according to the polling slot information.

It should be noted that the polling timeslot information is a host/slave communication timeslot table pre-stored at the host, and the host completes communication between the slave terminals at the host through timeslot allocation by recording the timeslot name, timeslot number, timeslot maximum length, and timeslot function.

Table 1: master/slave communication time slot table

In this embodiment, when the master performs polling on a plurality of slaves, the polling time slot of each slave is preset to 80ms, and after each slave performs the internal polling process, the master allocates a number to each slave in its allocated time slot, and the allocated time slot is preset to 300ms.

As shown in fig. 4, the master sends a polling command to each slave according to a polling sequence number during polling, so that the slave feeds back a polling response command to the master when receiving the polling command.

Step S200, when receiving the polling response instruction from the slave end, judging whether the current polling is finished, if so, sending number distribution initial information to a plurality of slave ends.

Specifically, when the master side is polling, after sending a polling instruction to the slave side, if a polling response instruction of the slave side is received, whether current polling is completed is judged, and if yes, number allocation starting information is sent to a plurality of slave sides.

As shown in fig. 4, it should be noted that, when waiting for receiving a polling response instruction, if the polling response instruction at the target slave end is overtime, the overtime count is incremented by 1, and it is determined whether the overtime count exceeds a preset value; if yes, deleting the polling information of the target slave terminal; if not, executing the step of judging whether the current polling is finished or not.

In a preferred embodiment, if the current polling is determined not to be completed, the polling sequence number is increased by 1, and the polling step is executed on a plurality of slave terminals based on the polling sequence number.

And step S300, when the number distribution response information of the slave end is received, storing the number distribution response information and sending the equipment number distribution information to the slave end corresponding to the number distribution response information.

Specifically, the master side waits for the slave side to feed back the number assignment response information to the master side after sending the number assignment start information to the slave side.

As shown in fig. 4, when the number assignment response information of the slave side is received thereafter, it is necessary to store the number assignment response information and transmit the device number assignment information to the corresponding slave side based on the number assignment response information.

It should be noted that, when the host receives a polling response instruction fed back by the slave according to the polling instruction, the timeout count is cleared.

As shown in fig. 4, in a preferred embodiment, after sending the device number assignment information to the slave side corresponding to the number assignment response information, the master side sends number assignment end information to the slave side, and determines whether the current polling sequence number exceeds the stored number of the slave sides;

The embodiment of the invention also provides an automatic topology identification method for the indoor distribution system equipment, and referring to fig. 5, fig. 5 is a flow diagram of a second embodiment of the automatic topology identification method for the indoor distribution system equipment.

Step S400, when a polling instruction of a host end is received, judging whether the polling instruction is a polling instruction for the host, if so, sending polling response information to the host end.

Specifically, the slave is used as a communication receiving end, and is prepared to receive information sent by the master at any time and to respond or not to respond according to the content of the information.

As shown in fig. 6, in this embodiment, when the slave receives the host information, if the information is polling information, it is determined whether the polling information is a polling command of the slave.

It should be noted that, when receiving the polling command from the host, the slave sends the polling response message to the host only when the polling command is a polling command of the host.

Step S500, when the number distribution starting information is received, judging whether the code counter is 0, if so, sending number distribution response information to the host end, and resetting the code counter; if not, the coding counter is decreased by 1, and the step of judging whether the coding counter is 0 is returned to be executed.

Specifically, if the master information received from the slave is code allocation start information and a code is not allocated, it is determined whether the code counter is 0.

As shown in fig. 6, further, when the encoding counter is 0, the slave side sends the encoding allocation response message to the host side, and resets the encoding counter; and when the coding counter is not 0, subtracting 1 from the coding counter, returning to the step of judging whether the coding counter is 0 until the coding counter is 0, and sending coding distribution response information to the host side again.

In step S600, the code counter is controlled to stop decrementing when the number assignment end information is received.

Specifically, when the slave receives the code allocation end information from the host, the slave controls the code counter to stop decrementing.

In a preferred embodiment, as shown in fig. 7, the number counter is obtained by:

(1) Reading the equipment serial number of the slave end;

(2) If the equipment serial number is successfully read, generating a random number by taking the equipment serial number as a seed, and taking the random number as an extension number;

(3) If the reading of the equipment serial number is unsuccessful, generating a random number by taking system count as a seed, taking the random number as a serial number, generating a random number by taking the serial number as a seed, and taking the random number as an extension number;

(4) And generating a number counter by taking the extension number as a seed.

The embodiment provides an automatic identification method for equipment topology of an indoor subsystem, which uses polling time slots to sense the in-place state of slave machines and acquire running state information of the slave machines through a host machine end, and allocates equipment numbers to slave machines which are not allocated with equipment numbers through allocating time slots, so that the technical problems that the efficiency of allocating the slave machine numbers to the existing indoor subsystem is low, and the installation cost of the indoor subsystem is high are solved.
