At present, photovoltaic base stations, communication Power supplies, UPSs (uninterruptible Power supplies), electric vehicles, energy storage Power stations and the like all use a storage battery as a backup Power Supply in a large amount. The reason for the sudden explosion and fire of a large number of existing data rooms is that most of the accidents are caused by the faults of storage batteries. The source is that the user is not aware of the current health of the battery at all, and therefore lacks the necessary maintenance measures.

Therefore, real-time monitoring of the battery is indispensable.
At present, some large enterprises, large data centers, base stations and the like have a set of complete local monitoring systems to avoid the occurrence of similar accidents. However, similar accidents often occur because the existing monitoring systems are expensive. The existing monitoring method cannot realize remote mobility for monitoring the storage battery, needs 24 hours of uninterrupted manual nursing, and has quite high operation and maintenance cost, time waste and labor waste. Moreover, because some operation and maintenance personnel are not professional, the potential risk cannot be judged at all, and thus tragedies occur. For small enterprises and some individual users, in the face of high monitoring cost, no monitoring measures are probably provided, so the tragedies are frequent.

It will be appreciated that the collection device 100 reports to the central device 200 raw operational data of the battery collected in real time. The central device 200 selectively converts all or part of the original data into target operation data for analysis according to a preset communication protocol, and encapsulates the converted data into a data packet that can be recognized by the server.

Further, the server 400 is further configured to receive the communication protocol sent by the communication device 300. The server 400 is further configured to receive a data packet sent by the communication device 300, and parse the data packet according to a communication protocol sent by the communication device 300 to obtain the operation data of the battery.
Specifically, the battery operation data is transmitted in the form of a byte stream between the server 400 and the communication device 300. The carrier of the communication protocol may be a document file, in which the acquisition command sent by the server 400 and the data format and conversion manner of the data to be returned corresponding to the acquisition command and what meaning (such as voltage, temperature, internal resistance, etc.) each several bytes of the returned data represent are recorded, the server 400 issues the acquisition command based on the communication protocol, and intercepts, converts, calculates, and obtains the operation data of the battery carried therein based on the communication protocol, and stores the obtained data in a database.

The set may be divided according to the working area or the battery pack. The same set, for example: the same battery pack, the same workshop, the same base station, etc.
202. The server associates the operation data of the battery with the communication device and stores the association relationship in a database;
the communication device stores an ID for uniquely identifying its identity. And the server analyzes the data packet sent by the communication device according to a preset communication protocol to obtain the running data of the battery recorded in the data packet. And then, associating the obtained battery operation data with the ID of the communication device sending the operation data, and storing the obtained association relation in a preset database for subsequent analysis and query.
203. The server analyzes whether the operation data of the battery is abnormal or not;
specifically, whether the operation parameters and the operation state of the battery meet preset alarm conditions or not is analyzed, and if the preset alarm conditions are met, the abnormal operation data is judged. The alarm condition may be greater than or less than a preset alarm threshold, such as: the battery voltage is high, the alarm threshold is 13.8V (volt), the internal resistance is high, the threshold is 26.8, and the like; or, the operating state under normal conditions is not met, such as: normally it should be in a charged state, but currently it is in a non-charged state. In practical application, the alarm condition can be customized by a user.
204. If the alarm is abnormal, the server sends an alarm notification to the monitoring terminal bound with the communication device according to a preset alarm mode, so that the monitoring terminal outputs the alarm notification.
The monitoring terminal may include, but is not limited to: the mobile terminal such as a smart phone, a tablet computer, a portable computer and the like and other computer terminals such as a PC which can not process data in motion.

Please refer to fig. 3, which is a schematic flow chart illustrating an implementation of a remote battery monitoring method according to an embodiment of the present application. As shown in fig. 3, the method mainly includes the following steps:
301. after establishing data transmission connection with the communication device, the server inquires whether the communication device completely returns response messages of successful configuration corresponding to all configuration commands in the database;
302. if not, the server forwards the configuration commands of the response messages which are not returned and correspond to successful configuration to the centralized device one by one through the communication device according to a preset sequence;
303. the centralized device executes configuration operation according to the configuration command and returns a response message of successful configuration to the server through the communication device so that the server sends the next configuration command;
304. the server stores the corresponding relation among the response message, the unique identification information of the communication device and the configuration command corresponding to the response message in the database;
305. if all the configuration commands are returned, confirming that all the configuration commands are sent;
306. when all the configuration commands are sent, the server forwards the acquisition commands to the centralized device through the communication device;
307. the centralized device sends the operation data of the battery collected by the collecting device to the server through the communication device according to the collecting command;
the communication device may be, for example, a communication cloud box for data forwarding. The centralized device may be, for example, a centralized box for data aggregation, converting raw collected data into target collected data of the type required for server analysis, and encapsulating the target collected data into data packets of a preset communication protocol. The communication device is connected with the concentration device, and the concentration device is connected with the acquisition device. The communication cloud box can automatically establish TCP connection with the server as long as power is supplied, and bidirectional communication is realized. Optionally, the communication cloud box establishes a long TCP connection with the server.
After the server successfully establishes TCP connection with the communication cloud box, the configuration commands are forwarded to the concentration box one by one through the communication cloud box according to a preset sequence. And the centralized box executes configuration operation according to the configuration command and returns a response message of successful configuration to the server through the communication cloud box. And the server sends the next configuration command to the centralized box through the communication cloud box only after receiving a response message of successful configuration returned by the communication cloud box. And meanwhile, the server stores the corresponding relation among the response message returned by the communication cloud box, the unique identification information of the communication cloud box and the configuration command corresponding to the response message in the database. And when all the configuration commands are sent, the server forwards the acquisition commands to the concentration box through the communication cloud box. And the centralized box reports the operation data of the battery acquired by the acquisition device to the server in real time through the communication cloud box according to the acquisition command.
In order to avoid repeated configuration, after the server establishes data transmission connection with the communication device, before sending the configuration command, the server queries whether all the communication devices return response messages corresponding to all the configuration commands, wherein the response messages correspond to successful configuration. If not, according to the preset sequence, the configuration command which does not return the response message corresponding to the successful configuration is forwarded to the centralized device one by one through the communication device. If all the battery operation data are returned, the acquisition command is directly forwarded to the centralized device through the communication device, so that the centralized device reports the battery operation data acquired by the acquisition device according to the command. That is, when the communication cloud box is connected to the server, the server first queries the database and determines whether the communication cloud box returns a successful configuration record for the configuration command. The configuration commands may be multiple ones, each configuration command corresponds to a successful configuration record, and the configuration records are recorded in the database in a one-to-one correspondence. And for the configuration command without the corresponding successful configuration record, the server issues the configuration command to the centralized box through the communication cloud box and waits for the response message of successful configuration returned by the centralized box, and for the configuration command with the corresponding successful configuration record, the server does not issue the configuration command to the centralized box any more.
Optionally, if the configuration command includes a self-checking command, the central apparatus executes a configuration operation according to the configuration command, and returns a response message of successful configuration to the server through the communication apparatus, including: the centralized device searches the acquisition devices connected with the centralized device according to the self-checking command, acquires the unique identification information of the connected acquisition devices, and sends a response message containing the searched unique identification information of the connected acquisition devices and the configuration success notification information to the server through the communication device when all the connected acquisition devices are searched.
Optionally, if the configuration command further includes a communication protocol configuration command, the central apparatus executes a configuration operation according to the configuration command, further including: the centralized device configures a target communication protocol carried in the communication protocol configuration command in the local device according to the communication protocol configuration command, wherein the target communication protocol is used for limiting the packaging format and the content of the operation data of the battery sent by the centralized device.
308. The server acquires the operation data of the battery acquired by the acquisition device and sent by the communication device;
the collecting devices may correspond to the batteries one to one, i.e. one collecting device corresponds to each battery, each battery having an ID, such as a unique serial number, for uniquely identifying its identity. Each acquisition device has an ID for uniquely identifying its identity and stores the ID of the corresponding battery. The acquisition device acquires the operation data of the battery in real time and sends the acquired operation data to the communication device. The operational data of the battery includes: operating parameters and operating conditions of the battery. Wherein the operating parameters of the battery may include, but are not limited to: voltage, temperature, internal resistance, etc. of the battery. The operating state of the battery may include, but is not limited to: a state of charge, a state of discharge, and a remaining amount of power, etc. Furthermore, the operation data of the battery may further include an ID of the corresponding battery and an ID of the corresponding acquisition device, so that when the operation of the battery is analyzed to be abnormal in the following, it may be determined which battery has the abnormality or which acquisition device has a fault according to the IDs.
Furthermore, for convenience of management, all the acquisition devices of the same set are connected to a centralized device, the acquisition devices transmit acquired operation data to the centralized device, and the centralized device packages the operation data of the battery transmitted by the acquisition devices into a data packet in a preset format according to a preset communication protocol and then transmits the data packet to the server through the communication device in a byte stream mode. The same set, for example: the same battery pack, the same workshop, the same base station, etc.
Optionally, the server receives a communication protocol used by the acquisition device sent by the communication device before issuing the acquisition command. The server sends an acquisition command to the communication device according to the communication protocol. And when the server receives the data packet sent by the communication device, analyzing the data packet according to the communication protocol to obtain the operation data of the battery. The carrier of the communication protocol can be a document file, and the document file records the acquisition command sent by the server, the data format and the conversion mode of the data to be returned corresponding to the acquisition command, and the meaning (such as voltage, temperature, internal resistance and the like) of each several bytes of the returned data. The server issues an acquisition command based on the communication protocol. Meanwhile, the server intercepts, converts and calculates the data packet returned by the communication device based on the communication protocol to obtain the operation data of the battery carried in the data packet, and stores the obtained data in the database. In this way, regardless of the protocol used by the centralized device, the server can analyze the data packet sent by the centralized device, thereby improving the compatibility of the monitoring system.
309. The server associates the operation data of the battery with the communication device and stores the association relationship in a database;
the communication device stores an ID for uniquely identifying its identity. And the server analyzes the data packet sent by the communication device according to a preset communication protocol to obtain the running data of the battery recorded in the data packet. And then, associating the obtained battery operation data with the ID of the communication device sending the operation data, and storing the obtained association relation in a preset database for subsequent analysis and query.
310. The server analyzes whether the operation data of the battery is abnormal or not;
specifically, whether the operation parameters and the operation state of the battery meet preset alarm conditions or not is analyzed, and if the preset alarm conditions are met, the abnormal operation data of the battery is judged. The alarm condition may be greater than or less than a preset alarm threshold, such as: the battery voltage is high, the alarm threshold is 13.8V (volt), the internal resistance is high, the threshold is 26.8, and the like; or, the operating state under normal conditions is not met, such as: normally it should be in a charged state, but currently it is in a non-charged state.
Optionally, the monitoring terminal obtains an alarm threshold value input by the user based on an alarm setting operation of the user, and sends the alarm threshold value to the server. The server stores the received alarm threshold in the database, and analyzes the operation data of the battery based on the alarm threshold to determine whether the battery is abnormally operated when step 310 is executed. For example: when the server analyzes the operation parameters of the battery, the analyzed operation parameters are correspondingly compared with the alarm thresholds in real time, and if the operation parameters exceed or are lower than the alarm thresholds, the data are considered to be abnormal.
311. If the operation data of the battery is abnormal, the server sends an alarm notification to the monitoring terminal bound with the communication device according to a preset alarm mode, so that the monitoring terminal outputs the alarm notification.
