All other embodiments, which can be made by one of ordinary skill in the art based on the embodiments herein without making any inventive effort, are intended to be within the scope of the present application.
Along with the development of internet technology, the internet of things technology is widely applied to daily life, great convenience is brought to life, and building management is advanced as an application aspect of the internet of things technology. The building management and control system combines information elements related to building application and management by using sensor technology, information acquisition and processing technology, embedded computer technology and the like, and provides a safe and convenient environment for building managers and users.
As shown in fig. 1, in the building management system, the system includes a hardware device, a data acquisition gateway and a building monitoring platform. The hardware equipment comprises data sensors based on various communication protocols and is used for acquiring data in the building, such as the on-off state of lamps in the building, the state of fans in the building, the state of an air conditioner, the starting of monitoring equipment and the like. The data acquisition gateway is used for converting the communication protocol of the data sensor into a communication protocol suitable for the data acquisition gateway, so as to acquire sensing data and send the sensing data to an acquisition data center in the building monitoring platform.
The system comprises a data acquisition gateway, an acquisition gateway management system and a data acquisition gateway, wherein the acquisition gateway management system in the building monitoring platform is used for sending an instruction to acquisition software in the data acquisition gateway and controlling the data acquisition gateway to acquire sensing data of a data sensor indicated in the instruction. The acquisition configuration center is used for configuring a link for acquiring sensing data through acquisition software, so that the sensing data of the data sensor is acquired through a data acquisition code in the acquisition software.
Taking the sensing data acquired by the data sensor based on the modbus protocol as an example, the following description will be given: and sending a first instruction through a data acquisition code integrated in acquisition software based on a data sensor of a modbus protocol, and sending sensing data to the acquisition software based on the modbus protocol by the data sensor based on the modbus protocol according to the first instruction. The data acquisition gateway transmits the sensor data based on the modbus protocol to an acquisition data center.
As shown in fig. 1, in an intelligent building, communication protocols corresponding to data sensors for collecting data such as a switching state of a lamp, a state of a fan in the building, a state of an air conditioner, and starting of monitoring equipment are respectively a modbus protocol, a bacnet protocol, an opc protocol, and a nonstandard protocol defined by equipment manufacturers, namely a protocol 1. Because the communication protocols adopted by different data sensors are different, a data acquisition code is embedded in the data acquisition gateway and is used for converting the communication protocol adopted by the data sensors into the communication protocol corresponding to the data acquisition gateway, so that the sensing data in the data sensors are acquired.
However, in the prior art, in order to be compatible with the communication protocols, a code development and deployment specific to each communication protocol are required in the data acquisition gateway, so as to implement protocol conversion on data based on various communication protocols.
In the prior art, an integrated software program or an application code acquisition software is arranged in a data acquisition gateway. The data acquisition software comprises data acquisition codes corresponding to each communication protocol, and data based on the communication protocols are converted through the data acquisition codes. Wherein, the data acquisition codes corresponding to various communication protocols are deployed in one code.
Therefore, each time a device with a new communication protocol joins the internet of things, it is necessary to redeploy and develop the code in the acquisition software, i.e. add a data acquisition code corresponding to the new communication protocol, so that the data acquisition gateway can also perform protocol conversion on the data based on the new communication protocol. Therefore, the flexibility is poor and the efficiency is low when the data acquisition codes corresponding to the new communication protocols are added in the acquisition software.
Therefore, in order to solve the problems in the prior art, the present application proposes a control method of a data acquisition gateway, in which data acquisition codes corresponding to each communication protocol are separately separated from acquisition software, so that each communication protocol corresponds to a data acquisition code. When a new communication protocol is added, the data acquisition codes corresponding to the new communication protocol are added, and the data acquisition codes corresponding to other communication protocols are not modified. When the data sensor based on the new communication protocol is provided, the efficiency and the flexibility of the corresponding data acquisition code are increased in the acquisition software, and the development time of the corresponding data acquisition code is reduced. And the related workload of joint debugging, redeployment and the like of the data acquisition codes and hardware in the data acquisition gateway is reduced, and the related risk brought by upgrading and redeployment of the system is reduced.

The implementation main body of the method in this embodiment may be, for example, a data acquisition gateway shown in fig. 3, where a plurality of data acquisition codes respectively corresponding to communication protocols of different types of data sensors are integrated in the data acquisition gateway shown in fig. 3, where each data acquisition code is mutually independent.
The method in this embodiment may be implemented by software, hardware, or a combination of software and hardware. As shown in fig. 2, the method may include:

The target data sensor is a data sensor for acquiring currently required sensing data, and the data acquisition code is used for converting a communication protocol applicable to the corresponding data sensor into a preset communication protocol.
The preset communication protocol is a communication protocol applicable to the data acquisition gateway.
In this step, for the application scenario shown in fig. 1, in the intelligent building, the communication protocols corresponding to the data sensors for collecting the data such as the on/off state of the lamp, the state of the fan in the building, the state of the air conditioner, and the start of the monitoring device are respectively a modbus protocol, a bacnet protocol, an opc protocol, and a nonstandard protocol defined by the equipment manufacturer, that is, protocol 1.
Therefore, in order to acquire data acquired by the data sensor based on each communication protocol, as shown in fig. 3, in the data acquisition gateway, the data acquisition codes corresponding to each communication protocol are individually separated from the acquisition software, so as to obtain the data acquisition codes corresponding to the modbus protocol, the bacnet protocol, the opc protocol and the protocol 1 respectively. I.e., modbus protocol data acquisition code, bacnet protocol data acquisition code, opc protocol data acquisition code, and protocol 1 data acquisition code.
The data acquisition codes are used for converting the communication protocol applicable to the corresponding data sensor into a preset communication protocol. The preset communication protocol is a communication protocol corresponding to the data acquisition gateway, so that the data acquisition gateway can realize the conversion of the communication protocol between the data acquisition gateway and the data sensor, and further the sensing data of the data sensor can be obtained.
The method is described by taking the sensing data of the data sensor based on the modbus protocol as an example on the basis of the data sensor shown in fig. 3: the acquisition software sends a first instruction to the modbus protocol data acquisition code, the modbus protocol data acquisition code sends a second instruction to the data sensor based on the modbus protocol according to the first instruction, the data sensor based on the modbus protocol sends sensing data to the modbus protocol data acquisition code after receiving the second instruction, and the modbus protocol data acquisition code sends sensing data to the acquisition software after receiving the sensing data.
Based on the data acquisition gateway shown in fig. 3, for example, a period of sensing report data in each data sensor can be preset in the acquisition software, and for a target data sensor, when the acquisition period corresponding to the number of data sensors arrives, the acquisition software determines a target data acquisition code corresponding to the target data sensor, and the target data acquisition code corresponding to the target data sensor acquires the acquired sensing data.
In some possible embodiments, before S201, the method of this embodiment further includes:

Specifically, for the data acquisition gateway shown in fig. 3, when a data sensor based on a new communication protocol is added in the intelligent building, in order to acquire the sensing data of the new data sensor, a data acquisition code corresponding to the communication protocol of the new data sensor is added in the data acquisition gateway.
The user develops a source code of the data acquisition code corresponding to the communication protocol of the new data sensor, compiles the source code, and obtains the data acquisition code corresponding to the communication protocol of the new data sensor. The user adds the data acquisition code corresponding to the communication protocol of the new data sensor to a preset catalog document of the data acquisition gateway so that the data acquisition gateway can acquire a data acquisition code adding instruction, and thus the data acquisition code corresponding to the communication protocol of the new data sensor can be acquired according to the data acquisition code adding instruction.
The preset catalog document comprises a plurality of data acquisition codes, for example: modbus protocol data acquisition code, bacnet protocol data acquisition code, opc protocol data acquisition code, and protocol 1 data acquisition code.
The process of developing the source code of the data acquisition code corresponding to the communication protocol of the new data sensor by the user is as follows:
step 1, the user knows the parameter information such as the coding format, the initial bit number, the data bit number, the parity bit number, the stop bit number, the error checking mode and the like of the new communication protocol.
And 2, compiling a source code of a data acquisition code for communicating with the data sensor based on a new communication protocol, and verifying and testing, namely compiling a downlink communication code.
And 3, compiling an interface (such as starting, stopping and collecting) for the collection software to call according to an interface format agreed by a new communication protocol, and packaging a source code of a data collection code which is communicated with the data sensor in the step 2 in the interface, so as to realize a defined interface in the collection software, namely compiling an uplink communication code.

and step 1, configuring and starting a test environment (comprising data sensor configuration, communication line configuration and building monitoring platform starting, and starting acquisition software in a data acquisition gateway).
And 2, adding a data acquisition sensor based on a new communication protocol to the test system.
And 3, adding the name of the new communication protocol to the building monitoring platform, wherein the naming specification is the name of the communication protocol of WeChat.

And 5, configuring and adding measurement point (acquisition point) information based on the data acquired by the new data sensor to the building monitoring platform.
And 6, inquiring whether the sensing data acquired by the new data sensor is written in or not according to the measuring point in the building monitoring platform and checking the accuracy of the sensing data (the aim is mainly to verify the function of reading the sensing data).
And 7, performing data writing test on the building monitoring platform, and checking whether the data is correctly written into the new data sensor.
For example, the switching state of the lamp is switched by a new data sensor.
Step 8, ending the test after the data acquisition code test corresponding to the communication protocol of the new data sensor passes; otherwise, the reason of the problem needs to be found out, and the source code of the data acquisition code corresponding to the communication protocol of the new data sensor is modified and then tested until the test passes.
Because a plurality of data acquisition codes which are independent from each other and respectively correspond to the communication protocols of the data sensors of different types are integrated in the data acquisition gateway. Therefore, when a new communication protocol is added, the data acquisition codes corresponding to the new communication protocol are added, and the data acquisition codes corresponding to other communication protocols are not modified. Therefore, after the data acquisition codes corresponding to the new communication protocol are added to the data acquisition gateway, only the data acquisition codes corresponding to the new communication protocol are required to be tested, so that the workload related to joint debugging, redeployment and the like of the data sensor is reduced, and the testing time of the data acquisition codes in the data acquisition gateway is shortened.

The current communication protocol is a communication protocol applicable to the target data sensor.
In this step, the data sensor may store the acquired sensing data in a designated storage unit of the data sensor, and after determining the target data acquisition code, the target data acquisition code is operated to acquire the sensing data stored in the designated storage unit of the data sensor according to the target data acquisition code.
The sensing data acquired by the target data acquisition code is transmitted by adopting a communication protocol based on the data sensor, so that the target data acquisition code is required to convert the sensing data transmitted by the communication protocol based on the data sensor into a preset communication protocol used by the data acquisition gateway, and the data acquisition gateway can acquire the sensing data.
In the control method of the data acquisition gateway provided in this embodiment, a plurality of data acquisition codes which are independent from each other and respectively correspond to communication protocols of different types of data sensors are integrated in the data acquisition gateway, where each data acquisition code is independent from each other. In this way, when the sensing data of the data sensor is acquired, determining a target data acquisition code corresponding to the target data sensor from a plurality of data acquisition codes; and acquiring sensing data acquired by the target data sensor according to the target data acquisition code, and converting the acquired sensing data from a current communication protocol to a preset communication protocol to acquire sensing data applicable to the data acquisition gateway.

And when the data sensor based on the new communication protocol is provided, the efficiency and flexibility of corresponding data acquisition codes are increased in acquisition software, and the development time of the corresponding data acquisition codes is reduced.
Based on the embodiment shown in fig. 2, for the data acquisition gateway, the overall process of the control method is as follows:
