[ Detailed description ] of the invention
The power distribution station room acquisition system is divided into three units, namely an acquisition model, a resource object and operation data. The collection model is configured to generate resource objects, the resource objects generate service data through operation, the implementation main bodies of the three units are different, the collection model is configured by system developers, the resource objects are configured by engineering implementation personnel, and the service data are generated through operation of the system.
The present embodiment relates to a method for generating an acquisition model, where the acquisition model includes an alarm model, a measurement model, a device model, an equipment model, and a protocol model, as shown in fig. 1. The resource object includes a device object and a device object. The business data comprises real-time data, history curves, alarm output, acquisition links, statistical analysis and operation logs. As shown in fig. 2, there is a logic diagram of model object operation, in each unit and between units there is a connection, in each unit is a weak connection, in each unit is a strong connection, the model is a high abstraction of the object, the object is an instantiation of the model, all the models are collectively called as collection models, all the objects are collectively called as resource objects, the collection models should be built according to the requirements in the business engineering, and the resource objects are created through guidance, so as to finally reach the operation data required by the business engineering.
The acquisition model is the key of an acquisition system, and defines data to be acquired, a data acquisition method and a data processing rule. When the acquisition model is established, corresponding acquisition protocols are customized or configured according to the data acquisition modes of acquisition devices and acquisition equipment products on the market, the acquisition devices are also used as a special acquisition object for more complete acquisition management, namely, the operation data of the acquisition devices also need to be configured with the corresponding acquisition protocols and alarm rules, and the configuration sequence is as follows: alarm model- > measurement model- > protocol model- > device model- > equipment model. The acquisition model is a basis of an acquisition system and is also a core unit, the accuracy of service data is directly affected by the configured acquisition model, engineering construction staff can construct a device model and an equipment model of a resource object according to the device model and the equipment model, and the configuration is required according to the condition of site construction during the establishment. The business data is automatically generated according to the configuration of the acquisition model and the resource object, and is also the purpose of construction of business engineering.
Each model in the acquisition model is in a weak relation, intelligent matching is carried out between the models through model names and application ranges, the application ranges represent the application range of the data, for example, the voltage application range is a specific grade of voltage, and the temperature application range is a region where the temperature is located. The model names are strictly matched, the application range is intelligent matching, the intelligent matching is the same as the preferential matching, if the matching is successful if the matching is only, if a plurality of models exist, the highest score in other parameters is obtained, each model has a respective parameter scoring algorithm, if no matching model exists, the matching is performed through the empty application range, and if the matching is not successful, the model matching is reminded to fail. The name rule of the model is simplified through the joint matching mode, so that the gravity center of the model configuration is biased to an application scene, and the engineering is facilitated.
The design of each module is described in detail below:
1. Alarm model:
The alarm model is a strategy model adopted for data change to judge whether the data is correct. Two types of telemetry and telemetry are classified according to data types. Telemetry refers to analog quantity having a continuously varying value, such as temperature; the remote signaling refers to a status bar, which is a value that varies between constants, such as water logging.
The telemetry alarm model is divided into an upper limit, a lower limit and a lower limit according to the change of the value, wherein a normal data interval is arranged between the upper limit and the lower limit, and the upper limit and the lower limit emphasize the processing strategy that the data exceeds or is lower than the normal value too much.
As shown in FIG. 4, the remote signaling alarm model is a processing strategy for changing a value from one state to another state, the state before the change can not be set to be an alarm for indicating that any state is changed to the set state, the state after the change can not be set to be an alarm for indicating that the starting state is regardless of the state to which the change is performed, and the state before the change and the state after the change cannot be set to be null at the same time.
Tables 1 and 2 are telemetry alert model samples and telemetry alert model samples, respectively:
Table 1:
table 2:
| Name of the name | Description of the invention | Start state | End state | Application range |
| RevDir_phsA | Phase A tide reverse | Positive direction | Negative pole | |
| RevDir_phsB | Phase B tide reverse | Positive direction | Negative pole | |
| RevDir_phsC | C-phase tide reverse direction | Positive direction | Negative pole |
Alarms are classified into general, serious, and significant three categories according to severity. The general grade indicates that the data in the state is abnormal, has potential safety hazard, can continue to run, and can be processed together when being maintained next time; the severity level refers to the data defect in the state, and the abnormality needs to be repaired, so that the abnormality can be repaired on line; the significant level refers to the data fault in the state, and the operation needs to be stopped immediately, so that the problem data can not be operated until the data is recovered.
The alarm processing strategies are divided into voice broadcasting, mobile phone short messages, voice phones and picture pushing. The voice broadcasting and the picture pushing refer to an alarm output mode adopted in the watch desk mode, and the mobile phone short message and the voice telephone are started in the background and can be executed no matter whether the watch desk exists or not.
The data change also contains two special jump values and dead data. The jump value data is far beyond a reasonable value or the change occurs in the state data which does not exist, the dead data means that the telemetry value is not changed for a long time, and the two types of data are not in the alarm category.
2. And (3) measuring a model:
the measurement model is an abstraction of the data domain, and comprises measurement names, attribute descriptions, data types, measurement units, alarm models, application ranges and whether important data exist. The data types are remote signaling and remote measurement, and the application range is used for accurately matching the police model and the follow-up protocol model of the user.
The name of the measurement model is unique, all the devices are not provided with own value field names, the problem that the names defined by the data fields of all the factories are inconsistent is solved, for example, the A-phase voltage of an electric meter of an X manufacturer is represented by Ua, the A-phase voltage of an electric meter of a Y manufacturer is represented by UA, different names represent the same data field, and the use of a unified measurement model also simplifies the alarm configuration workload of the devices of different manufacturers and also simplifies the subsequent operation and maintenance work.
The measurement model is built so that data exchange between different system platforms is simplified, names of equipment of different manufacturers are shielded, an external interface has a unique data domain name, and the expression is readable. Table 3 shows some of the data of the metrology model, and the system should continue to expand new metrology models as the application does not expand.
Table 3:
3. Protocol model:
In communication, data transmission should be performed according to a predetermined format, and the transmitting and receiving ends should deal with the transmission rate, synchronization mode, data structure and the like in advance and follow each other, and these conventions are called communication conventions. The protocol model comprises a communication mode and a communication protocol, wherein the communication mode is also called an acquisition link, comprises a physical channel and data communication characteristics, and the communication protocol is also called an exchange rule and comprises an operation process and a data format of information exchange. Fig. 4 is a schematic diagram of a protocol model communication mode.
The communication modes are divided into serial ports, networks and wireless. The most important parameters for serial communication are baud rate, data bits, stop bits and parity, which must be matched for the two ports communicating, more commonly (9600, n,8, 1).
Communication conventions are divided into standard conventions and proprietary conventions. The standard specifications include the Modbus specifications of the industry, IEC101, IEC104, DL/T645 of power, and the like. The proprietary specifications are self-designed according to each manufacturer's product, and support for a southbound interface (Southbound Interface) and a northbound interface (Northbound Interface) is required for access to be compatible with third party specifications.
The communication protocol not only describes a synchronous mode but also comprises a data structure, sometimes called a point table, different manufacturers use the same protocol mode, but the data structure is inconsistent, the protocol model solves the problem that the different manufacturers are inconsistent in the data structure by introducing the measurement model, the data structure only exists in the protocol model, only provides measurement data externally, namely has uniform data names, such as DL/T645 protocol is adopted by electric meters, single X electric meter manufacturer UA is stored at 0001 register addresses, Y electric meter manufacturer UA is stored at 0088 register addresses, and the external data acquired by different electric meter positions of different data names of different manufacturers are provided as measurement model data, namely only comprises standard Ua measurement data. Table 4 is a protocol model data structure example.
