In order to illustrate the technical scheme of the invention, the following description is made by specific examples.
As shown in FIG. 1, a dynamic configuration method of a plug and play TTU comprises a TTU1, a distribution network master station 2, a plurality of distribution master stations 3 and a plurality of external devices 4; specifically, TTU1 includes 101/104 protocol module 10 and high-level application module 11, and 101/104 protocol module 10 includes device management module 100; the 101/104 protocol module 10 can be connected with external equipment for dynamic configuration, and synchronizes the dynamic configuration result to the advanced application module 11; the advanced application module 11 can perform remote meter reading management on the dynamically configured equipment and upload meter reading results to the power distribution main station 3; the device management module 100 is capable of dynamically configuring a plurality of external devices 4, including assigning information body addresses, conventions, and configuration data items. Further, all external devices 4 are connected with the TTU1 through a dual-mode medium, wherein the dual-mode medium is wireless, broadband power carrier (HPLC), or broadband power carrier connection. The 101/104 protocol module 10 is in communication connection with the distribution network main station 2, and the communication protocol is the power grid 101/104 protocol; the high-level application module 11 is in communication connection with the power distribution main station 3, and the communication protocol does not comprise the power grid 101/104 protocol; 101/104 protocol module 10, high-level application module 11. It should be noted that, the transmission protocol of the power grid 101/104 protocol is an inherent transmission protocol of the distribution network, and is connected with the distribution network host station to realize data transmission and receive all commands issued by the distribution network host station, including remote control, parameter setting and archive setting.
As shown in fig. 2, the method for dynamically configuring the external device 4 by the 101/104 protocol module 10 includes the following steps:
S1, the 101/104 protocol module 10 resets the key identification of the 101/104 transmission protocol; including designating the link address as unique; setting a default address of the public address as an id number of the external device 4;

s5, the equipment management module 100 dynamically configures equipment in the global point table;
And S6, the 101/104 protocol module 10 respectively transmits the global point table to the advanced application module 11 and the distribution network master station 2.
TABLE 1 device archive sheet
Further, step S4 includes the steps of:
S41, if only the equipment items are added in the equipment to be updated, the 101/104 protocol module 10 reads the records of a plurality of online equipment in the first equipment file, sequentially writes the records into a global point table (the global point table refers to the table 2 and the table 3), reads the records of a plurality of equipment to be updated, and writes the records into the global point table. After the step is completed, a plurality of online devices are in one-to-one correspondence with the first device file and the global point table;
s42, if the equipment to be updated comprises equipment items to be deleted, the 101/104 protocol module 10 deletes the records of the equipment to be deleted one by one in the first equipment file; and writing the records of the rest devices in the first device file into the global point table in turn.
Step S5 comprises the steps of:
S51, if only the equipment items are added in the equipment to be updated, the equipment management module 100 allocates the information body addresses one by one for the equipment to be updated and configures the data items;
S52, if the equipment to be updated comprises the equipment item to be deleted, the equipment management module 100 distributes information body addresses for all the equipment in the global point table and configures the data item.
After step S6 is completed, the plurality of devices in the second device archive complete dynamic configuration sequentially according to steps S2-S6. The plurality of devices in the second device archive are accessed and deleted devices which are not dynamically configured; or deleted devices that are not dynamically configured; or an accessed device that is not dynamically configured. The records of the first device file and the second device file comprise device types and device id numbers.
The above is the main step of the plug and play technology. When the medium-voltage equipment and the low-voltage equipment are accessed, the TTU1 needs to be accessed seamlessly, and data of newly added equipment such as equipment type and equipment id number is acquired dynamically, and the data of other online equipment is not influenced; meanwhile, newly accessed equipment data on the distribution network master station 2 also needs to be accessed seamlessly, and TTU1 power failure cannot occur. Moreover, the new access device needs to actively request network access, and cannot influence networking and meter reading data requests of the rest of the online devices. The device files are dynamically managed when plug and play is realized, the distribution network master station transmits the files to the 101/104 protocol module 10, the 101/104 protocol module 10 synchronizes the files to the advanced application module 11 to realize the synchronization of the device files, and the 101/104 protocol module 10 reads a device file table according to the device type and additionally generates a global point table so as to realize the interaction of the three-remote data and the distribution network master station.
And each power distribution master station needs to acquire the generated global point table in real time, otherwise, the data displayed by each power distribution master station is not in one-to-one correspondence with the actual equipment data. Thus, after adding or deleting devices, the topology of each distribution master station area also needs to be regenerated, and the global point table also needs to be re-established.
In this embodiment, the 101/104 protocol module 10 receives the device files, and sends the files and the global point table to the relevant advanced application modules 11, and each advanced application module 11 recognizes which devices are newly added and which devices are deleted, and respectively uses those model devices, and implements management of different acquisition tasks of different model devices by comparing the global point table with the original file. Further, the 101/104 protocol module 10 and the advanced application module 11 are storage media readable by the TTU1, and the storage media stores a program capable of running on the TTU1, and the program is capable of implementing S1-S6 of the method and all relevant steps when executed. Preferably, the external device 4 is a medium and low voltage device.
As shown in fig. 3-4, at present, the establishment of the topology diagram and the establishment of the point table of each distribution main station 3 are added manually one by one, and are applicable to the conditions of less medium and low voltage equipment and less information body addresses. However, for the application scene of the medium and low voltage equipment, thousands of information body data exist in a TTU1 medium and low voltage station area; moreover, for the medium and low voltage distribution network models, equipment is added or deleted at any time; for the network topology already established by the network distribution master station 2, the information body addresses of the devices are distributed, and in the case that a link is already established, adding or deleting a device will result in a non-one-to-one correspondence of the information body addresses. Thus, the conventional grid 101/104 protocol is not applicable and requires appropriate modification.
Several key identifiers exist in the power grid 101/104 protocol: public address, link address and information body address. At present, the conventional protocol and the current distribution network master station 2 agree that the public address and the link address are the same address, and the default is 1. The typical 68-packet protocol in the 101 protocol, the public address is defined as the terminal address, and defaults to TTU1 address. The public address is modified to the id of the device, i.e. the dev_id value in the device profile. When the device management module 100 dynamically configures the device, the information body address is preferably a table_pro_add, dev_id and a table_pro_add in a device point table (not illustrated), that is, a specific data can be uniquely distinguished, and the process is also applicable to the 104 protocol. If the public address is 2 bytes, 65535 devices can be indicated, already enough for one low voltage station area. Each frame of message only transmits telemetry or remote signaling data of one device, the public address is dev_id address, and each distribution main station 3 can distinguish which device the frame data is, and which device the data is through the information body address.
By modeling the devices, a device can be simply added or deleted when a certain device is added or deleted, and related data items and information body addresses can be automatically added because a model of the device exists. The plug-and-play model from the equipment to the master station is simply and conveniently realized, the later maintenance cost is greatly reduced, and the method is very suitable for medium-voltage and low-voltage distribution network models.
As shown in tables 2-3, two global point table modes can be flexibly selected. First, the information body addresses of each type of device are the same, and the distribution network master station 2 and the distribution master station 3 distinguish specific data of which device according to the public address and the device id, and analyze and display the data. Secondly, the information body address sequence of each device in the global point table is increased, the global is unique, and the distribution network master station 2 and the distribution master station 3 distinguish specific data of the devices according to the information body addresses and analyze and display the data. Which is used is specific to the specific situation of the master station distribution network master station 2 and the power distribution master station 3.
