Description

The utility model relates to devices for automating energy accounting and dispatching of energy, industry and housing and communal services, providing processing, storage, transformation and exchange of information with collection servers.

From the prior art, a telemechanics controller is known, taken as the closest solution, containing a printed circuit board on which a processor module and a communication module connected in parallel to it, a power supply module, an interface module, a signal input / output module and a real time clock module are located, while the power supply module is connected to the communication module, to the interface module, and to the real-time clock module (see Patent RU 150636, published on February 20, 2015).

The disadvantage of the closest solution is the lack of the possibility of duplicating the GSM wireless information transmission channel, the lack of the possibility of uninterrupted data transmission over long distances in the event of a loss of the communication signal.

The technical problem solved by the utility model is the creation of such a device that is capable of transmitting information over LPWAN (LoRaWAN protocol) and GSM radio channels both simultaneously and in duplication mode.

The technical result of the utility model is to expand the functionality of the telemechanics controller by ensuring the possibility of uninterrupted transmission of data on the state of energy, industry and housing and communal services via the LPWAN radio channel (LoRaWAN protocol) over long distances (up to 40 km).

The technical result of the utility model is achieved due to the fact that the telemechanics controller contains a printed circuit board on which a processor module and a communication module connected in parallel, a power supply module, an interface module, a signal input/output module and a real time clock module are located, the power supply module is connected to the module communication module, with an interface module and with a real-time clock module, while on the printed circuit board there is a transmission and control module with a radio module, as well as SMA connectors connected in parallel to the radio module through the transmission and control module and to the communication module, and the radio module through the transmission module and control module is connected in parallel with the processor module and with the power supply module.

In addition, the radio module can be based on LPWAN technology and has a microcontroller with software and a transceiver.

In addition, the controller is provided with an SD card holder connected to the processor module.

Also, the controller can be equipped with an indication module connected in parallel with the processor module and the power supply module.

In addition, a SIM card holder connected to the communication module may be located on the printed circuit board.

The utility model is illustrated by a drawing, the figure of which shows a block diagram of the components of the proposed telemechanics controller MKP-23.

The proposed telemechanics controller (which also has the name Software and hardware complex “MKP-23 radio controller”, hereinafter referred to as the MKP-23 radio controller) is a small-sized programmable device (software and hardware complex (STC) of the monitoring and power quality control system at the substation level). The proposed controller is made in the form of a single printed circuit board with a power input and on which there are electronic components responsible for monitoring power supply, for solving problems of automation of production sites and for controlling access to facilities.

The following electronic components are located on the printed circuit board of the proposed controller: a transmission and control module, which includes connector 1 and a radio module 2 connected to it, a communication module 3 (module 3 of the data transmission network (DTN) and coordinates, hereinafter referred to as module 3 of DTN and coordinates ), power supply module 4, processor module 5, interface module 6, signal input/output module 7, real time clock module 8, SIM card holder 9, SMA connectors 10 for external antennas. In this case, an SD card holder 11 (SD card slot) and a display module 12 can also be additionally placed on the printed circuit board.

All listed components (modules) of the proposed telemechanics controller are mounted on a single printed circuit board and connected to each other as follows.

Connected in parallel with the processor module 5 are a power supply module 4, a SPD and coordinates module 3, an interface module 6, a signal input/output module 7, a real-time clock module 8, an SD card holder 11, an indication module 12, and a transmission and control module ( in particular radio module 2 via connector 1). At the same time, the specified connection provides two-way communication of the processor module 5 with the radio module 2, with the SPD and coordinates module 3, with the interface module 6, with the signal input / output module 7 and with the SD card holder 11 (i.e., the transmission of signals from the processor module 5 to the specified components and back from them to the processor module 5). Also, such a connection provides one-way communication of the processor module 5 with the power supply module 4 (power supply from module 4 to module 5), with the real-time clock module 8 (one-way signal transmission from module 8 to module 5), with the display module 12 (one-way signal transmission from module 5 to module 12).

In addition to the processor module 5, the power supply module 4 and the SMA connector 10 for external antennas are connected in parallel to the radio module 2 via connector 1 (with a transmission and control module). Moreover, connector 10 has two-way communication with radio module 2, and module 4 has one-way communication.

SMA connector 10, SIM card holder 9 and power supply module 4 are also connected in parallel to the SPD and coordinates module 3 in addition to the processor module 5. Moreover, connector 10 and holder 9 have two-way communication with module 3, and module 4 - one-way communication.

Also, the power supply module 4 is connected to the interface module 6, to the real time clock module 8, and to the module 12, providing power to these components.

The transmission and control module is the main transceiver module of the proposed MKP-23 radio controller (telemechanics controller), which incorporates a microcontroller and a 2 LPWAN radio module. Through the connector 1 located on the printed circuit board, the LPWAN radio module 2 is electrically connected to the corresponding components located on the printed circuit board in order to control them and exchange commands. The transmission and control module is the main element of the transmit-receive path of the MKP-23 radio controller (performs the functions of sending data on the state of energy, industry and housing and communal services, and receiving control commands) and includes a microcontroller with special software installed on it, as well as a transceiver (LPWAN transceiver radio module) that performs two-way communication with base stations (including servers). Radio module 2 operates on the basis of LPWAN technology (mainly LoRaWAN protocol), which provides data transmission with telemetry readings over long distances (up to 40 km). Radio module 2 LPWAN can be replaced with another one using radio transmission based on other data transmission technologies ZigBee, UNB, etc. The microcontroller is responsible for processing received and transmitted information and performing all logical functions, interacts with the relevant components located on the printed circuit board, receives processes the information received from them, processes the LoRaWAN protocol, exchanges commands with base stations and servers. The LPWAN transceiver module (transceiver) ensures the operation of the radio frequency communication channel.

The use of the proposed telemechanics controller together with the SPT module 3 and the coordinates of the transmission and control module, including connector 1 and radio module 2, ensures the transmission of information via LPWAN and GSM radio channels both simultaneously and in duplication mode. As a result, in case of absence or temporary loss of the communication signal (GSM), the proposed controller, due to the presence of a radio module 2, will ensure uninterrupted transmission of data on the state of energy, industry and housing and communal services via the LPWAN radio channel (LoRaWAN protocol) over long distances (up to 40 km).

Processor module 5 (CPU, RAM, ROM, RTC) is the main computing module of the proposed telemechanics controller (MKP-23 radio controller), which includes a central processor, RAM, permanent memory with special software installed on them. The processor module 5 is responsible for processing and exchanging data between the transmission and control module on the one hand, and between the interface module (RS-485, RS-232, FE, USB) and the signal input output module (GPIO) on the other hand. The processor module 5 also provides processing and data exchange, both simultaneously between the radio module 2 and module 3, and separately and independently of each other. In case of loss of the GSM signal during data transmission, the processor module 5 exchanges signals and commands with the radio module 2, ensuring the uninterrupted operation of the proposed controller, including synchronizing the operating time thanks to the 8-hour real-time module.

Interface module 6 (RS-485, RS-232, FE, USB) is responsible for the exchange of data between the processor module 5 of the MKP-23 radio controller and external devices used to automate the accounting of energy resources and dispatch energy, industry and housing and communal services facilities via wired data transmission channels . In this case, all received data from external devices can be transferred to the collection server both via GSM communication channels using module 3, and via the LPWAN radio channel using radio module 2, ensuring continuous and uninterrupted transmission and data exchange.

Signal input/output module 7 (GPIO) is responsible for controlling external actuators and transmitting discrete signals from external sensors to processor module 5 for processing with subsequent transmission to the transmission and control module. At the same time, in case of loss of the communication signal when using module 3 of the SPT and coordinates, thanks to the radio module 2 with connector 1, reception and transmission of signals and commands to and from external sensors is provided at any time necessary for prompt response.

The SPD and coordinates module (GSM, LTE, GPS, Wi-Fi) is responsible for the exchange of data between the processor module 5 of the MKP-23 radio controller and external devices used to automate the accounting of energy resources and dispatch energy, industry and housing and public utilities facilities via wireless data transmission channels, and also determines the geographical coordinates of the location of the MKP-23 radio controller and receives the exact time signals from satellites.

The power supply module (~220V, =12-24V) is responsible for providing power to the components of the MKP-23 radio controller, including the transmission and control module (radio module 2), processor module 5, interface module 6, signal input / output module 7, SPT module 3 and coordinates.

The display module 12 is responsible for displaying the operation status of the proposed telemechanics controller (MKP-23 radio controller), including in the absence of the module 3 communication signal, displaying the controller's operability via a radio channel using radio module 2.

SMA connectors for external antennas are responsible for connecting external antenna-feeder devices to the transmission and control module and module 3 of the SPT and coordinates.

The SIM card holder is designed to install SIM cards of telecom operators in order to organize data exchange between the processor module 5 of the MKP-23 radio controller and external devices used to automate energy accounting and dispatch energy, industry and housing and communal services facilities via wireless data transmission channels.

The SD card slot is intended for installing flash memory cards in order to expand the permanent memory (ROM) of the MKP-23 radio controller, if necessary.

The 8 real-time clock module provides synchronization of the proposed controller's operating time, including in the event of a loss of connection between the controller and the server through module 3, maintaining the connection between the controller and the server via radio module 2 with real-time display.

The proposed telemechanics controller (MKP-23 radio controller) may have a housing that includes a base element and a removable cover (not shown). At the same time, a connector for fastening the telemechanics controller to a DIN rail is fixed on the base element. In the presence of a housing, the printed circuit board is rigidly connected (by screw connection) to the base element.

Also, to form the electrical circuit of the controller, transistors, resistors, diodes, LEDs, and jumpers are located on the printed circuit board.

The presence of the above functionality makes it possible to implement, on the basis of the proposed MKP-23 radio controller, the functions of automating energy accounting, dispatching of energy, industry, housing and communal services and transmitting data on the state of energy, industry and housing and communal services via LPWAN radio channels (LoRaWAN protocol) and GSM.

The functionality of the proposed device is implemented as follows.

The microcontroller of the transmission and control module (radio module 2) is programmed to receive and transmit data on the operation of the MKP-23 radio controller, as well as to control the operation of all components included in the MKP-23 radio controller in accordance with the algorithms specified by the software (firmware).

Reception and transmission of data from the MKP-23 radio controller is performed using a radio channel using a 2 LPWAN radio module transceiver. Reception, transmission and processing of information are carried out by a remote specialized monitoring software center.

The MKP-23 radio controller is also controlled via a radio communication channel using the LoRaWAN protocol. Reception and processing of information is carried out by specialized software of the microcontroller. Programming of the proposed telemechanics controller (MKP-23 radio controller) is carried out via the USB connector.

Remote control of the MKP-23 radio controller is carried out by sending commands from the server to the radio module 2 LPWAN. When receiving a command, the LPWAN radio module 2 transmits information to the microcontroller, which processes this command and then transmits control signals to the appropriate components. If it is necessary to send information to the server, the microcontroller generates a data packet and transmits it to the transceiver of the radio module 2 LPWAN for sending.

Thus, the presence of the specified functionality will make it possible to implement a wide range of functions on the basis of one MKP-23 radio controller, namely:

safe and uninterrupted reception and transmission of commands from the server to the MKP-23 radio controller and vice versa for the purpose of automating energy accounting, dispatching of energy, industry, housing and communal services and uninterrupted transmission of data on the state of energy, industry and housing and communal services via the LPWAN radio channel (LoRaWAN protocol);
