Description

FIELD OF TECHNOLOGY

The invention relates to systems and methods for collecting and storing information about a technical device and its functioning parameters. In particular, the invention relates to a remote request for information about a technical device, including its functioning parameters, and the subsequent use of the collected data.

BACKGROUND

Technical devices, as you know, have a certain period (resource) of work and the shelf life established by the manufacturer. The term of operation (resource) can be considered as one or more events related to the on-off of a technical device. There is a need for a sensor system, a method of accumulating and retrieving information about the operation of the device, including the time worked by it, in such a way as to make the information easily accessible and convenient for use by the user.

Known sensor system for collecting product data, which contains a computer, a polling device and an electronic circuit on a flat basis (film) - a label that includes at least one sensor, an radio frequency integrated circuit and an antenna. The sensor is adapted to produce an output similar to a change in the ambient conditions of the sensor. The sensor generates an analog signal and contains output contacts. The radio frequency integrated circuit contains a memory element, input contacts and output contacts. The input contact (s) is in electrical communication with the output contact (s) of the sensor. The antenna is in electrical communication with the output contacts of the radio frequency integrated circuit (RU 2601183 C1, 10.27.2016). The method of collecting data about the product using this sensor system consists in embedding a system tag in the product, on which the radio frequency integrated circuit, antenna and sensor are located, using a polling device, polling the status of the label and reading information from the memory of the radio frequency integrated circuit, analyze and / or interpret the information and create a sound and / or visual and / or tactile output of information (ibid.).

The necessary power supply for the sensors and the integrated circuit can be provided by the energy collected by this circuit, but the electric power is supplied to the circuit only when it is exposed to a polling device. The disadvantage of this system and method when they are used for recording and storing the functioning parameters of a technical device that does not have power supply, including the time it has spent a resource, is the inability to record product parameters and the time it worked out during its operation in the absence of a polling device and a power source .

Known dual-port memory M24LR64 for radio frequency identification devices manufactured by STMicroelectronics (journal. Electronics News, No. 8 (88), 2010, p. 20), in which a traditional radio frequency tag type RW with a standard radio frequency ISO15693 wireless communication interface with RFID readers ISO15693 standard, an EEPROM memory access chip has been added using the standard I2C serial interface, which provides interaction with most microcontrollers and is widely used in custom specialized microchips (ASIC), as a means of communication with microcontrollers, as well as in the microchip there are real-time clocks.

Known non-volatile EEPROM-memory, for example, the company Dallas Semicunductor ("Non-volatile static memory (NV SRAM)" http://www.cqham.ru/super/dallas/nvsram.htm), in the housing of which is integrated a power source, as which In particular, a capacitor, a microprocessor can be used to control the process of recording and downloading data and a real-time clock.

The disadvantage of non-volatile EEPROM memory is the lack of the ability to record information about the parameters and operating time of the measured device, as well as the possibility of obtaining (removing) data on the operating time and functioning parameters of the measured device

Known sensors based on LIS331DLH chips manufactured by MOUSER ELECTRONIC (3-axis 16 bit Accelerometers, https://ru.mouser.com/Sensors/Motion-Position-Sensors/Accelerometers/Datasheets/_/N-axgd7?P = 1z0w8k6Z1ynyo5t) whose communication with the control electronics takes place via the PC protocol and which require power supply to operate.

The disadvantage of the sensors is that power is required for operation, which significantly increases the power consumption of the sensor system.

Closest to the proposed are a sensor system for collecting product data and a method for collecting data using this system according to the above patent RU 2601183.

The sensor 4 can be installed on the technical device 1 separately from the electronic circuit (Fig. 1), or it can be located on the same basis 8 with the electronic circuit (Fig. 2).

In FIG. 3 shows an embodiment of a sensor system with an indication of the end of a resource. An indicator 9 of the end of the resource (service life) of the technical device 1 (made, for example, of electronic paper), placed on a viewable surface of the technical device 1, is indicated in the sensor system.

The sensor system shown in FIG. 1, implements the proposed method of collecting information about the technical device as follows.

The electronic circuit and sensor 4 of the sensor system are located on the technical device 1 so as to provide the greatest sensitivity of the sensor 4 and antenna 7 for taking parameters of operation using the polling device 2, designed to read information about the technical device 1.

Before shipment of the technical device 1 from the manufacturer, the electronic circuit is scanned by the interrogation device 7, while the elements of the electronic circuit are activated and the scan date (date of the first read), the assigned resource of the technical device 1, and the end date of the designated life are recorded in the memory of the radio-frequency integrated circuit 6 technical device 1 with simultaneous locking and setting a password for writing to the memory of the radio-frequency integrated circuit 6. From now on, reading the info mation about the parameters of the technical device 1 operation may be performed only with a password. The assigned resource can also be written to the memory of the non-volatile integrated circuit 5.

When you turn on the operation of the technical device 1, the sensor 4 generates a signal, upon the fact of which, a non-volatile integrated circuit 5 is saved in the memory of the functioning parameters of the technical device 1 and the corresponding moment (or date) of real time.

When you turn off and shut down the technical device 1, the signal of the sensor 5 disappears, and the real-time mark of the completion of the technical device 6 is entered into the memory of the non-volatile integrated circuit 5.

The next time you turn on the cycle repeats.

During the cycle, the recording of the functioning parameters of the technical device 1 occurs at a frequency specified by the program of work of the processor of the non-volatile integrated circuit 5.

At the end of each cycle, the operating time of the technical device 1 is determined by summing the integrated processor non-volatile integrated circuit 5 time intervals between the times of each inclusion in the work and the completion of the technical device; the value of the total time worked is recorded in the memory of the non-volatile integrated circuit 5 and its comparison with the assigned resource recorded in the memory of the non-volatile and / or radio-frequency integrated circuit 5, 6.

During the routine inspection of the technical device, the polling device 2 reads the identifier, the date of the first reading and the end date of the designated life from the memory of the radio frequency integrated circuit 6, and also removes the password for writing data to the memory of the radio frequency integrated circuit 6; at the same time, data on the parameters of the technical device 1 is transmitted from the memory of the non-volatile integrated circuit 5 to the memory of the radio-frequency integrated circuit 6 and to the polling device 2, where they are displayed on the screen of the polling device 2, and the amount of information is determined by the free capacity of the memory of the radio-frequency integrated circuit 6. Next, all data can be transferred from the polling device 2 to the memory of an external computer 3.

Information about the identifier of the technical device 1, the date of its shipment (date of first reading), the end date of the assigned service life and the hours worked are displayed on the screen of the polling device 2. Also, the data on the functioning parameters of the technical device 1 are transferred from the memory of the non-volatile integrated circuit 5 to the external computer 3. If the total operating time is equal to or exceeds the designated resource, this information is also displayed on the screen of the polling device 2.

On the external computer 3 is the processing of the operating parameters.

The sensor system shown in FIG. 3, 4, implements the proposed method of collecting information about the technical device as follows.

The electronic circuit and sensor 4 of the sensor system are located on the technical device 1 so as to provide the greatest sensitivity of the sensor 4 and antenna 7 for taking parameters of operation using the polling device 2, designed to read information about the technical device 1.

Before shipment from the manufacturer of the technical device 1, the electronic circuit is scanned by the polling device 2, and the date of the first reading and the end date of the designated life is recorded in the memory of the radio frequency integrated circuit 6 with the simultaneous blocking of the recording of dates in the memory of the radio frequency integrated circuit 6. Set the password on unlocking the recording of dates in the memory of the radio frequency integrated circuit 3 and write the assigned resource in the memory of the non-volatile integrated circuit 5 and / or into the memory of the radio frequency integrated circuit.

From this moment, information on the parameters of the technical device 1 can be read only with a password.

When you turn on the technical device 1, the sensor 4 gives a signal, upon the fact of which there is a record in the non-volatile memory 2 of the functioning parameters of the technical device 1 and the corresponding real-time marks.

When the technical device 1 is turned off and shut down, the signal of the sensor 4 disappears, and a mark (moment or date) of real time is entered into the memory of the non-volatile integrated circuit 5. In this case, the processor of the non-volatile integrated circuit 5 summarizes the time worked over all previous cycles of the technical device 1 and compares this value with the assigned resource stored in the memory of the non-volatile integrated circuit 5 and / or the radio frequency integrated circuit 6. If the value of the total time worked is equal to or greater than the assigned resource, the processor of the non-volatile integrated circuit 5 issues a command to activate the control element 10 (electronic key), which changes the state of the resource indicator 9 of the technical device 1. In the presence of a second antenna 11 and an integrated circuit in the sensor system 12, the radio signal for the end of the life of the technical device 1 is turned on, which is received by the external, relative to the technical device 1, radio receiving system.

If the value of the total time worked is less than the assigned resource, the next time the technical device is turned on, the cycle repeats.

During each cycle of operation of the technical device, the recording of operating parameters occurs at a frequency specified by the program of work of the processor of the non-volatile integrated circuit 5.

When reading, the polling device 2 gives a command to transfer the total worked time of the technical device 1 to the memory of the radio frequency integrated circuit 6, at the same time, the data on the parameters measured by the sensors 4 begins to be transmitted from the memory of the non-volatile integrated circuit 5 through the memory of the radio frequency integrated circuit 6 and through the polling device 2 in the memory of an external computer 3, and the amount of information is determined by the free capacity of the memory of the radio frequency integrated circuit 6.

At the same time, the identifier of the technical device 1 is read from the memory of the radio frequency integrated circuit 6, the date of the first reading, the end date of the designated life, and the password for writing dates to the memory of the radio frequency integrated circuit 6 is also removed.

Information about the identifier of the technical device 1, the date of its shipment from the manufacturer (the date of the first reading), the end date of the assigned service life and the term of the fulfilled resource is displayed on the screen of the polling device 2. Also, the functioning parameters of the technical device 1 are transferred to an external computer 3.

On an external computer 3 is processing the parameters of the functioning of the technical device.

Various embodiments of the present invention are described below. The description is illustrative, and it does not describe every possible variant of the device on the same principles, since a description of each possible embodiment of an electronic circuit is impossible.

System manufacturing examples.

In this embodiment (Fig. 1), the electronic circuit of the system comprises a radio frequency tag and a non-volatile integrated circuit 5 containing an integrated power supply, memory, and a processor for controlling the recording and transmission of data. At least one sensor 4 generates data that is recorded in the memory of the non-volatile integrated circuit 5. The sensor system also includes a polling device 2 and at least one external computer 3 with a database located on it.

The RF tag contains a radio frequency integrated circuit 6 containing memory and input and output contacts, and an antenna 7 in electrical communication with the output contacts of the radio frequency integrated circuit 6. The RF tag contains input contacts that are connected to the output contacts of the non-volatile integrated circuit 5, input contacts which are connected to the output contacts of the sensor 4.

The RFID tag is based on 8. Examples of base materials (film, rigid, single layer and multilayer) include: polyester, paper, high dielectric permittivity and FR-4 refractory material. Multi-layer structures may also include partial layers of non-conductive material separating the conductive layers, for example, copper and silver inks or copper and silver foil.

The radio frequency integrated circuit 6 may be active or passive. The antenna 7 may have the physical shape of a coil or a symmetrical vibrator.

The interrogation device 2 comprises a power source and an antenna adapted to generate electromagnetic radiation, including the resonant frequency of the first antenna 7, as well as a receiver adapted to detect the electromagnetic radiation of the antenna 7 and to demodulate it by extracting embedded data from the detected radiation. The interrogation device 2 is a reader for radio frequency identification, which has the ability to interrogate an RF tag, determine the memory status of an RF integrated circuit 6, and retrieve information related to information of a sensor 4 or sensors measuring operation parameters of a technical device 1 on which a sensor 4 is located. The polling device 2 also contains a secondary communication channel using the Bluetooth ^tm communication protocol to transmit information extracted from the radio frequency tag to an external a polling device, such as a computer or smartphone with Bluetooth ^tm connected. The interrogation device 2 can additionally analyze information related to the state of the RF tag and / or the parameters of the technical device 1 on which the RF tag is installed, and generate data associated with a specific RF tag and / or parameters of the device on which the sensor 4, which is located in composition of the sensory system.

The interrogation device 2 may also include one or more cameras capable of capturing images associated with the technical device 1, an RF tag, or environmental conditions. The polling device 2 may provide for global positioning, allowing the polling device 2 to establish and provide collective access to information related to the geographical location of the polling device 2.

As the interrogation device 2, a smartphone can be used that can interrogate the RF tag to obtain information from the memory of the radio frequency integrated circuit 6. The interrogation device 2 can analyze or otherwise interpret the information and can display it on the screen or transmit it for subsequent processing on an external computer 3 Information can also be delivered to the user of the sensor system through audio output, visual output, tactile output, or combinations thereof. When creating the output, the polling device 2, in addition to the RFID information, can use inputs from sensors or smartphone systems.

The sensor system contains an external secure computer 3, on which a database is located, which allows you to: identify the technical device 1, record and process the functioning parameters of the technical device 1 during its operation. Computer 3 has secure Internet access.

An example implementation of the method.

The method of collecting information about the technical device on the example of a propeller blade was carried out as follows. In the manufacture of the blade, the electronic circuit is implanted in the blade in such a way that it is impossible to remove it without destruction. After the manufacture of the blade, the unique identification number of the RFID tag is read, which is recorded in the database of the external secure computer 3, at the same time, other identification features of the blade are recorded in the database that allow the blade to be uniquely identified. At the same time, a ban is placed on writing to the memory of a non-volatile integrated circuit 5. When a consumer shades a blade or screw into which the blade enters, the identification number of the RF tag is re-read, the write lock on the non-volatile integrated circuit 5 is removed, and the real-time clock of the non-volatile integrated circuit processor 5 is activated . At the beginning of the blade operation (rotation), the sensor 4 is activated, the switching signal of which is recorded in the memory of the non-volatile integrated circuit 5. One the real-time value is recorded at a time. At the end of the blade operation, the signal of the sensor 4 disappears, while the signal to turn off the sensor 4 and the real-time value are recorded. When you turn it on again, the cycle repeats and the values of the difference between the turn-off time and the turn-on time of the sensor 4 in each cycle are summed by the processor of the non-volatile integrated circuit 5. This value is the total operating time of the blade.

If the value of the total operating time of the blade exceeds the value of the assigned resource of the blade recorded in the memory of the non-volatile integrated circuit 5 (or radio frequency integrated circuit 6), then the processor of the non-volatile integrated circuit 5 triggers the indicator 10 control element 10, as a result of which the state of the indicator 9 changes, when At the same time, a visual signal of the end of the assigned resource is formed on the surface of the blade.

In one embodiment of the system, if it has a second antenna 11 and an integrated circuit 12 generating a radio signal, the control element 10 includes this integrated circuit 12. In this case, the radio signal generated by the second antenna 11 is received by an external, for example, on-board radio receiving system, notifying of the end assigned resource.

Also, the formation of a visual and radio signal for the end of the assigned resource occurs if the current real-time value exceeds the assigned blade service life recorded in the memory of the non-volatile integrated circuit 5.

The readings of the sensors 4 of the parameters of the technical device are also recorded in the memory of the non-volatile integrated circuit 5 for subsequent reading by the device 2 of the survey and transmission to an external computer 3 for subsequent processing.

When scanning the radio frequency label of the blade, the signal of the polling device 2 generates a signal in the antenna 7, which in turn triggers the radio frequency integrated circuit 6, which starts the program for reading the time worked by the blade, as well as transmitting the blade operation parameters 3 to the external computer database.

To implement the method, a polling device 2 is used, adapted to detect radiation associated with radio frequency tag data. The polling device 2 may be an RF or NFC reader associated with Bluetooth ^tm support, as described above, or a smartphone or other computing device containing an RF reader, possibly with NFC support.

The polling device 2 can be used to determine the current state of the RF tag using an RF communication protocol such as the NFC protocol. The polling device 2 can interpret the data received from the RF tag using a software application written for this purpose.

An RF tag can be read, for example, using a radio frequency protocol such as Near Field Communication (NFC).

In one embodiment, the polling device 2 may comprise a secondary network communication module, allowing the polling device 2 to send and receive data over a cellular telephone network or other networks, including local area networks or WiFi networks. In such an aspect, the polling device 2 may transmit data received from an electronic circuit or a data analysis result, if provided by the software application of the reader. The software application of the interrogation device 2 can also analyze the data from the electronic circuit to determine whether it is necessary to stop using and replace the blade with the integrated electronic circuit, or to plan when it will be necessary to repair or replace the blade. In this aspect, the application can be used to determine the need for preventive maintenance or repair.

In one embodiment, the conductive Velcro fasteners can be used to create an interface between the functional environment surrounding the blade and the outer surface of the blade. The mechanism for fastening the blades, the sensor, and the removable RFID tag to ensure conductivity can be a Velcro fastener, compression fastening (for example, elastic strip, garter), adhesive fastening (for example, adhesive strip), magnetic fastening, or combinations of these types of fastening . In this embodiment, the antenna and the non-conductive coating system can be made in the form of a node in electrical contact with the conductive Velcro fastener elements, which, in turn, are located on the outer surface of the blade, while the antenna and the non-conductive coating system are located inside the blade. Corresponding Velcro fastener elements may be included as part of the antenna of the radio frequency integrated circuit, and the two antenna parts may be combined using Velcro fastener elements for the functional use of the RF tag. Thus, the more expensive integrated circuit assembly can be reusable, thereby reducing the total cost associated with using the system with a plurality of suitable disposable items. Corresponding nodes can be formed using a conductive adhesive to fix the electrical wires of the corresponding parts of the RF tags to the corresponding Velcro fastener elements.

Although specific embodiments of the invention have been illustrated and described, it will be apparent to those skilled in the art that various other changes and modifications can be made without departing from the spirit and scope of the invention.

The proposed system can be used on any technical devices, where an important requirement is to comply with the assigned service life and terminate the operation of the technical device at the end of the designated life and without power supply.

Such devices are widely used in space, rocket and aviation technology (for example, propellers, wheels and shafts of compressors and turbines of gas turbine engines, combustion chambers and nozzles of jet engines, wings and empennages of aircraft, heat protection of aircraft, etc.), as well as in power plants for various purposes (units of steam and gas turbines, electric generators, cases of various pneumatic and hydraulic systems) and in transport devices (wheels and transmission parts of cars and railways, shaft main marine shafts, etc.). To organize the optimal operation of technical devices and conduct timely and justified preventive repairs, it is important to obtain data on the operating parameters of technical devices during operation. The reading of these data is carried out either during the operation of the technical device, or during scheduled preventive repairs.
