In one embodiment, the monitoring method further comprises the steps of:

In this embodiment, the shielding monitoring server may obtain the location distribution of the signal shielding device for multiple times, and each time a new location distribution is obtained, the new location distribution may be compared with the original location distribution, and if there is a difference, it indicates that the location of the signal shielding device has changed, and at this time, it is necessary to determine the signal shielding device whose location has changed.
Specifically, the monitoring method may monitor a position change of the signal shielding device, where the position change of the signal shielding device refers to a placement position movement of the signal shielding device, and some places include: the examination room, examination room application environment is received at random from the equipment storehouse before the national examination, or increase examination room signal shielding equipment, or with the changing examination room in school district, these all involve the position change of signal shielding equipment, can lead to originally synchronous equipment to become the step-out, signal shielding equipment is not fixed at a certain examination room, when arranging examination environment before the examination, place signal shielding ware in the preceding position in classroom, a signal shielding equipment is placed to general every examination room classroom, 2 and above are placed to big examination room (over 100 square meters).
Because the signal shielding device is randomly received, the position information of each device is unknown, the signal shielding device can collect an air interface signal, the PCI of the nearest base station Cell is obtained by analyzing the signal, the PCI is fully called Physical Cell Identifier, namely Physical Cell Identifier, the wireless signals of different cells are distinguished in LTE according to the Physical Cell Identifier, the signal shielding device comprises an antenna port, the signal shielding device sends a heartbeat data packet to the LoRa transparent transmission device through a network interface according to a certain protocol, the heartbeat data packet comprises shielding device position information (Cell PCI and antenna port corresponding to the base station radiation region nearest to the shielding device), a signal synchronization state, an alarm state, a shielding channel switch state, shielding signal strength, a master-slave state and the like, the shielding device is converted and modulated into the LoRa signal to be sent through the LoRa transparent transmission device, wherein the LoRa signal is added with LoRa node ID and received by a concentrator under the coverage of the LoRa signal, and the concentrator also collects the LoRa node signal strength, and then forwarded to the shielding monitoring server through a wireless router (supporting a 2G/3G/4G/5G network).
The shielding monitoring server acquires a signal shielding equipment distribution diagram according to the received information, and compares the signal shielding equipment distribution diagram with the original distribution diagram acquired or recorded and stored to obtain the signal shielding equipment ID, the LoRa node ID and the number of the signal shielding equipment ID and the LoRa node ID with changed positions; the shielding monitoring server updates a signal shielding device distribution diagram, controls the working mode of a signal shielding device with changed position, generally preferentially sets the mode as a slave mode, preferentially selects a matched shielding model according to a signal shielding model prestored by the shielding monitoring server, configures the slave model parameters of each slave machine adapted to the same region, achieves the optimal shielding effect, does not interfere with an uplink base station, updates asset management information, and sends an alarm to a user in time after receiving the alarm.
For the movable signal shielding equipment, the position change of the shielding equipment can be effectively monitored in real time, and the asset management of the signal shielding equipment and the synchronization of a plurality of signal shielding equipment are facilitated.
In one embodiment, the monitoring of the signal shielding device by the shielding monitoring server according to the signal shielding information includes the following steps:
the shielding monitoring server acquires the signal synchronization state of the signal shielding equipment according to the signal shielding information; if a first signal shielding device with unsynchronized signals exists, sending a request synchronization control signal to the concentrator according to the signal shielding information of the first signal shielding device;
the concentrator transmits the synchronous control signal to the first signal shielding device in a mode of the target wireless signal;
and the first signal shielding equipment executes LTE search according to the synchronous control signal, acquires an optimal synchronous channel and a synchronous frequency point and sets optimal synchronous parameters.
In this embodiment, the shielding monitoring server may obtain the signal synchronization state of the signal shielding device according to the signal shielding information, and may regulate and control synchronization when the first signal shielding device is asynchronous to the signal, specifically, send a synchronization control request signal to the first signal shielding device through the concentrator, where the first signal shielding device corresponds to the synchronization control signal, perform LTE search, search for an optimal synchronization channel and synchronization frequency point, and set an optimal synchronization parameter, so that the first signal shielding device realizes signal synchronization.
Specifically, the monitoring method may further enable the signal shielding device to enter the synchronization state again after the signal shielding device is out of synchronization with the base station cell. In an actual application scenario, if a mobile operator changes the frequency point of a base station cell, both the fixed signal shielding equipment and the mobile signal shielding equipment are out of synchronization, and the solution is to obtain asynchronous equipment from a shielding monitoring server, change a synchronous channel, a synchronous time delay and a synchronous frequency point of the asynchronous equipment, and enable the signal shielding equipment to obtain synchronization again. The shielding monitoring server records the state historical data of the signal shielding equipment, and the state historical data can be used as reference for subsequent maintenance.
The shielding monitoring server obtains the information of the asynchronous equipment from the database, and the shielding monitoring server comprises: signal shielding equipment ID number, signal shielding equipment LoRa node ID, signal shielding equipment LoRa node signal strength, signal shielding equipment position information (cell PCI and antenna port corresponding to a base station radiation area nearest to a shielding device), master-slave state and signal synchronization information; by controlling the LTE searching function of the signal shielding equipment, the signal shielding equipment retrieves the optimal synchronous channel and the optimal synchronous frequency point and sets the optimal synchronous parameters, thereby achieving the purpose that the desynchronized signal shielding equipment quickly synchronizes the current network signals.
In one embodiment, the monitoring of the signal shielding device by the shielding monitoring server according to the signal shielding information includes the following steps:
the shielding monitoring server determines a second signal shielding device of which the software is not upgraded according to the signal shielding information and sends software upgrading data to the concentrator;
the concentrator transmits the software upgrading data to the second signal shielding equipment in a mode of the target wireless signal;
and after receiving the software upgrading data, the second signal shielding equipment is switched from a signal shielding monitoring mode to a software upgrading mode, and software upgrading is carried out according to the software upgrading data.
In this embodiment, the shielding monitoring server may analyze whether software in the signal shielding device is upgraded according to the signal shielding information, determine a second signal shielding device to which the software is not upgraded, send software upgrade data to the second signal shielding device through the concentrator, suspend signal shielding monitoring by the second signal shielding device, convert the signal shielding monitoring into software upgrading, and better perform signal shielding and monitoring after the upgrading is completed.
Specifically, in the long-term operation process of the signal shielding equipment, the software BUG is inevitable and needs to be upgraded; or because the parameters of the control signal shielding equipment do not meet the requirements due to the update of the operator network, and equipment software upgrading is also needed, but personnel cannot be sent to carry out field upgrading like a prison, a military base and the like, so that remote upgrading is completed through a monitoring system based on LoRa.
Because the communication rate of the LoRa network is not high, only one signal shielding device can enter the upgrading mode at the same time. During upgrading, the monitoring software operation modes of the signal shielding device can be divided into two types: a monitoring mode and a software upgrade mode. As shown in fig. 7, in the monitoring mode, the monitoring software of the signal shielding device normally collects various monitoring data of the signal shielding device and reports the generated alarm according to the setting, and the device only uses the protocol a in this mode. The shielding monitoring server sends a command of converting to a software upgrading mode and software upgrading contents to the signal shielding equipment through the concentrator, so that the signal shielding equipment enters the software upgrading mode to realize the function of remote upgrading. In the software upgrading mode, the monitoring software of the signal shielding equipment stops the functions of acquisition, warning and the like, and transmits and stores files. In this mode the device uses only the B protocol. When the software upgrading is completed or the upgrading cannot be normally completed due to an error in the software upgrading, the signal shielding device can enter the monitoring mode to work in an automatic software resetting mode. After the shielding monitoring server finishes remote upgrade, the shielding monitoring server can obtain a remote upgrade result (whether the remote upgrade is carried out to an expected version or not) by a method of actively reporting the software version number by the signal shielding equipment after the software of the signal shielding equipment is restarted.
