Description

The invention relates to devices for automated identification, integrity monitoring and accounting of objects in economic circulation, mainly located in conditions of increased radiation background or containing radiation sources inside, and can be used in various industries for organizing accounting and conducting inventories, and specifically in repositories of fissile materials.

A known system for remote reading of information for rolling stocks (RU 2170684 C1 from 10/18/2000, published on 07/20/2001), consisting of an electronic tag mounted on the object and / or on a locking-sealing device, stationary and portable readers and information processing centers .

The specified system allows to increase the quality, efficiency and information content of the control.

However, the known system cannot be used in conditions of increased radiation background due to the low radiation resistance of the microcircuit used in the tag.

A known installation for identifying objects (patent RU 2057334 C1 of 04/18/1991 publ. 03/27/1996) based on the use of a piezoelectric passive transponder placed on the object with an antenna carrying a characteristic code, data about the object and placed directly on each object to be identified, as well as a transmitting and receiving path of a reader with an antenna for radio sounding of an object, a threshold device, and an information processing unit with an indication device.

The specified installation is a prototype and can improve the accuracy of identification, as well as increase the reading range of information about the object.

The disadvantages of the known device is that this device does not allow for the accounting of objects, to determine the ways of moving objects, to control the integrity and condition of objects, and processing of stored information using computer technologies is not provided.

The technical task is to create a universal system that performs the functions of identifying objects, determining the path of their movement, monitoring the integrity and condition of objects in conditions of increased radiation background, as well as allowing to reduce the dose loads of maintenance personnel working in conditions of increased radiation background.

The technical result is expressed in the reduction of dose loads for personnel when carrying out work related to objects, determining the ways of moving objects, monitoring the integrity and condition of objects located in conditions of increased radiation background or containing radiation sources inside, increasing the reliability of information about metering and storage objects, reducing the role of the human factor.

This technical result is achieved due to the fact that at least one reader, which extracts the code from the piezoelectric passive transponder by means of radio sounding, introduces a sensor system into the identification system, including a piezoelectric passive transponder carrying a specific code located directly on each object to be identified for automatic or automated determination of the presence of an object in the area of the reader by a number of characteristic features, and automatic or automated control centers, processing and transmitting information from readers and sensor systems via optical communications, radio or wire connections, placed in an electronic database and processing using computer technology.

The reader in the identification system can be installed on an automatic or automated movement system equipped with sensors of its spatial position, the information from which is transmitted to an electronic database.

At least one wearable reader may be included in the identification system.

The identification system may include at least one reader of a barcode printed on the object, with the transfer of information to an electronic database.

The identification system may be equipped with an intervention indication device integrated with a piezoelectric passive transponder.

Introduction to the identification system of control centers, processing and transmission of information and a system of sensors to determine the presence of an identification object will determine the path of the object taking into account the direction of movement, exclude the identification of passive piezoelectric transponders not fixed to the object, which increases the reliability and reliability of identification. In addition, the determination of the presence of an object by a number of characteristic features using a sensor system allows you to turn on the reader only when the object is present and thus reduce the exposure of a person to high-frequency electromagnetic radiation.

Processing data located in an electronic database using computer technology allows you to determine the direction and path of movement of objects, to carry out their accounting.

Installing a reader on an automatic or automated moving system equipped with sensors for its spatial position allows for an inventory and to reduce the role of the human factor.

The presence in the system of identification of objects of at least one portable reader of piezoelectric passive transponders allows for an inventory in the absence of an automatic or automated moving system.

The presence in the system of identification of objects of at least one barcode reader allows an inventory of objects with a printed barcode, and to increase the reliability of the information.

The presence in the object identification system of interference indication devices integrated with a piezoelectric passive transponder will allow monitoring the integrity of the object and its condition.

A specific implementation of the system is presented in figure 1, and a possible arrangement of equipment of the system for identifying objects is shown in figure 2.

The object pos.2 (Fig.1) enters the premises 13 receiving / unloading objects (Fig.2). Here his initial identification takes place and information about him is entered into the database. In the case of using interference indication devices integrated with the piezoelectric passive transponder, item 3 (Fig. 1), in addition to identification, the integrity of the object is monitored. Upon receipt of a response from a piezoelectric passive transponder, item 3 (Fig. 1), a conclusion is made about the integrity of the interference indication device and, accordingly, about the integrity of the object. Otherwise, the integrity is violated, the object could have been opened. The object with suspicion of opening comes into a special room, and the information is recorded in the database. Further, the identified object can be moved on carts manually, on vehicles or through a conveyor. The entire route of objects through the rooms 14 and 15 (Fig. 2) is equipped with a kit for monitoring the passage of technological places pos. 11 (Fig. 1, Fig. 2), consisting of a system of sensors pos. 1 (Fig. 1) and reading devices pos .4 (Fig. 1), by means of control centers, processing and transmission of information pos.5 (Fig.1), connected to a computer pos.6 (Fig.1) located in the room of the control center 19 (Fig.2).

The sensor system is designed to determine the direction of movement of the object and its presence in the coverage area of the reader antenna pos.4 (figure 1). When approaching the object pos.2 (Fig.1), the sensor closest to it pos.1 (Fig.1) is triggered, and after a while, inversely proportional to the speed of movement, the next one. The time between the responses of the sensors is taken into account by the system through the control centers, processing and transmission of information pos.5 (figure 1). In case of successful determination of the code, about which the corresponding record is made in the database, the object can be moved further from this control position.

Data processing is designed to obtain an actual map of the passage of objects along the technological path, which increases the reliability of the information. The processing is as follows. If the time between the responses of the sensors for the presence of objects is too small or too long, the control center, processing and transmitting information pos.5 (figure 1) diagnoses a malfunctioning situation and does not start the reader pos.4 (figure 1) to determine the object code, о what is the corresponding record in the database done. If the time between the responses of the sensors for the presence of objects is within acceptable limits, the control center, processing and transmission of information pos.5 (Fig.1) starts the reader pos.4 (Fig.1) to determine the code of the object.

When the object pos.2 (figure 1) passes the entire technological path and is installed either in the storage room 16, 17, 18 (figure 2) or in the reception / unloading room 13 (figure 2), the final account is formed in the database containing links to records of the passage of each technological place. Depending on the starting point and on the basis of the analysis of the direction of the object’s movement, either an account for registration, or an account for deregistration, or an account about a violation in the passage of the technological chain is formed. Information about the object is stored in the database regardless of whether the object is registered or deregistered.

The inventory is carried out by means of an automated moving system pos.7 (Fig.1, Fig.2), equipped with a system of spatial position sensors X, Y, Z, with a kit placed on it for installation on an automated moving system pos.12 (Fig.1, figure 2), consisting of a reader of piezoelectric passive transponders with an antenna pos.8 (Fig.1) and a barcode reader pos.9 (Fig.1). Moving sequentially together with the automated moving system pos.7 (Fig.1, Fig.2) along the objects pos.2 (Fig.1), the reader of the piezoelectric passive transponders pos.8 (Fig.1) determines the presence and integrity of all storage objects with reference to the occupied place, the coordinates of which are determined by interrogating the spatial position sensors X, Y, Z of the automated movement system, and the barcode reader pos.9 (figure 1) determines the barcode of the object. All information about the received codes and spatial position is recorded in the database. Based on the information recorded as a result of the inventory, analysis using computer technology makes a conclusion about the number, location and condition of storage facilities.

It is permissible to conduct an inventory using a portable reader pos.10 (Fig.1, Fig.2) for operation in storage rooms 18 (Fig.2), not equipped with an automated moving system.

The reader may be a standalone device, i.e. the read codes of the piezoelectric passive transponders are located in its memory, not transmitted during the interrogation process to external systems. The codes recorded in the internal memory can be transferred to the database at the end of the inventory procedure by optical communication, radio or wired connection.

As sensors for the presence of an object, various kinds of optical sensors with or without a light guide, induction sensors, and capacitive sensors can be used.

Thus, the claimed combination of features is able to provide a new technical result.
