In implementing the invention, the stated task is solved by means of a technical result, which consists in ensuring operational safety by increasing the efficiency of identifying emergency and pre-emergency situations through diagnostics of the condition with the possibility of detecting violations at an early stage by ensuring control of physical, chemical and mechanical (in particular, such as temperature, pressure, humidity, gas contamination, vibration, etc.) parameters of the environment, the underground space and the elements of the raised floor structure (rack(s), stringer(s), slab(s) with the possibility of predicting critical modes of its operation and organizing timely diagnostic and technical maintenance.

The specified technical result is achieved by integrating into the raised floor structure an intelligent system containing a block and/or blocks of control and measuring instruments (HOST(s)), secured to the raised floor elements - stinger, and/or rack, and/or slab, a network concentrator (HUB(s)), implementing two-way continuous communication between the upper level of automation (in particular SCADA, PLC, PC, ARM, etc.) and the block of control and measuring instruments and automation (HOST(s), as well as software for the dispatch control and data collection system.

The design of the raised floor with an intelligent system ensures the use of a set of control and measuring devices installed on the structural elements of the raised floor, ensuring the possibility of timely notification of critical conditions,

Brief description of the drawings

The invention is illustrated by drawings, where: Fig. 1 shows a diagram of the architecture of an intelligent system, Fig. 2 shows a diagram of an example of integrating an intelligent system into a raised floor structure.

In Fig. 1, the diagram of the architecture of the intelligent system shows: 1 - HOST, 2 - sensor module, 3 - measuring instrument (MI), 4 - microcontroller (MC), 5 - data bus, 6 - HOST microcontroller (MC), 7 - non-volatile memory, 8 - interface unit (UI), 9 - digital data bus, 10 - HUB, 11 - communication module, 12 - interface unit (UI), 13 - microcontroller (MC), 14 - data bus, 15 - hub microcontroller (MC), 16 - non-volatile memory, 17 - communication unit (CU).

In Fig. 2, in the diagram of the integration of an intelligent system and a raised floor structure, the following are designated: 18,19,20,21 - HOSTS, 22 - HUB, 23 - connecting cable, 24 - upper-level automation equipment (which can be used, for example: a personal computer (PC), SCADA, programmable logic controller (PLC), automated workstation (AWP), etc.), 25 - raised floor structure rack, 26 - raised floor structure stringer, 27 - raised floor structure slab.

The number of HOSTs and HUBs depends on the size of the space (length, width, height), its purpose (the presence of process equipment, pipelines, gas pipelines, utility networks, electrical equipment, and power lines). One or more HUBs, one or more HOSTs, or several HOSTs and HUBs can be connected to a Hub.

The HOST (Fig. 2) consists of a data bus, which houses a power module, a communication module, and a set of unified measurement modules (the number depends on the parameters being measured). The power module supplies the HOST with voltage from the HUB. The communication module facilitates two-way data transfer between the HOST and the HUB, as well as data buffering on the storage medium. The unified measurement module can measure a range of physical/chemical/mechanical parameters and perform their initial analysis.

HOST 1 includes a sensor module(s) 2, a data bus 5, HOST MC 6, non-volatile memory 7, and BS 8. SI 3 is built into the sensor module to measure the parameters of the environment and the raised floor structure. Data bus 5 is intended for communication between the sensor module(s) 2 and HOST MC 6. Two-way data transmission between the HOST(s) and the HUB(s) is carried out via BS 8.

The HUB (hub) is a communication unit between the lower-level automation system (HOST) and the upper-level automation system (PC, SCADA, PLC, workstation), along with other HUBs and HOSTs. It consists of a data bus, which is equipped with at least a power module, a UART unit (if interfacing with a PC is required), and communication modules. The power module supplies the equipment with voltage from an external power source or the device to which the HUB is connected. The UART unit ensures two-way data transfer from the PC and data buffering on the storage medium. The communication module ensures two-way data transfer between the HUB and the slave device, as well as data buffering on the storage medium.

HUB 10 is a unit providing communication between the lower level of automation (HOST 1) and the upper one, other HUBs 10 and HOSTs 1. Communication module 11 is responsible for receiving data from HOST 1 or HUB 10, includes BS 12 and MK 13. MK of HUB 15 receives information from communication module 1 via data bus 14), processes and forms a data packet for sending to the upper level of automation or transmits to other HUB(s) via BC 17. Non-volatile memory (7,16) is intended for storing data, including when the power is turned off.

The IS can include several HOSTS 1 and HUBs 10. The use of the IS will allow for continuous monitoring (in particular, measuring parameters, receiving and transmitting emergency protection commands) of the environment and elements of the raised floor structure.

Implementation of the invention

The system works as follows.

In the structure, the raised floor is installed on the rack(s) (25), stringer(s) (26), plate(s) 27 HOST(s) 18,19,20,21, which are blocks of control and measuring instruments and automation, which are connected to the HUB(s) (10) via a cable.

The initial information for monitoring and control is provided by the sensor module(s) included in the HOST, which represents a measuring instrument and a microcontroller.

To convert the parameters obtained by SI 3, MK 4 is built into sensor module 2. After conversion, the sensor module data is received via data bus 5 by HOST MK 6, which forms a HOST data array and, via interface unit 8, sends it to communication module 11 of HUB 10 via digital data bus 9 – a link between the HUB/HOST/upper-level automation equipment. The formed data array from the HOST comes to communication module 11 via interface unit 12. MK 13 of the communication module serves to process and transmit data to MK 15 of the HUB via data bus 14. Communication unit 17 serves to connect the HUB with other HUB(s)/HOST(s)/upper-level equipment. HOST MK (6) and HUB MK 15 are responsible for buffering data arrays in non-volatile memory 7,16.
