The distributed control information system based on smart sensors contains multisensor smart sensors connected to each other by nodes for receiving and converting control commands into power signals and with an interface unit. Multi-sensor smart sensors are integrated into a distributed network, and any two multi-sensor smart sensors are bilaterally interconnected via at least two nowhere matching network sections. Each node receiving and converting control commands into power signals is connected to at least one multisensor intelligent sensor. The interface block with the operator is implemented using a device that provides selection, decryption and display of data from the information field, as well as the transmission of commands (settings) of the operator to the information field of the system.

The disadvantages of this analogue are the lack of self-diagnosis of system units, in addition, information cannot be guaranteed to be received for a given time interval, because if there is an exchange between a pair of subscribers, the rest are waiting for the end of the exchange and may “not have time” to capture the network for “their” exchange, there is no central device that controls this exchange, so there is a delay in the access time to the sensors.

As the closest technical solution, we consider the AUTOMATED FIRE PROTECTION MANAGEMENT SYSTEM (see, for example, RU 2135240, published on 08.27.1999), designed to ensure high-quality fire fighting in the event of an emergency.

Description of Embodiment of Utility Model

Elements of a utility model are shown in FIG.

The module 1 for monitoring the status of the address-analog loops (MAC) contains a microprocessor 2, connected through the buffer register 3 and the data bus 4 to the module 5 of the processor of the control and monitoring fire device (PPCP). Via the internal data transfer bus 6, module 1 is connected to the first controller 7 of the 200/500, 200AP protocol and at least one additional controller 8 of the 200/500, 200AP protocol. The first controller 7 of the 200/500, 200AP protocol is connected to the first address-analog loop 9 of the addressable devices through the first galvanic isolation unit 10 and the first control and switching unit 11 of the first loop.

In the described embodiment of FIG. 1 shows one additional controller 8 of the 200/500, 200AP protocol, however, an embodiment is possible in which the address-analog loop control module 1 contains many additional controllers 8 '(two additional controllers are shown in Fig. 2) of the 200/500, 200AR protocol the number of additional analog addressable loops 12 'of addressable devices (Fig. 2).

An additional controller 8 of the 200/500, 200AP protocol (Fig. 1) is connected to the address detector of the address-analog loop 12 of the addressable devices through an additional galvanic isolation unit 13 and an additional loop control and switching unit 14.

The first loop control and switching unit 11 is connected to the microprocessor 2 by communication lines 15 and 16 for transmitting information about a short circuit or a break in one of the analog addressable loops 9, 12, while the additional loop control and switching unit 14 is connected to the microprocessor 2 by lines 15 and 17 communication for transmitting information about connecting one of the address-analog loops 9, 12.

The first loop control and switching unit 11 and the additional loop control and switching unit 14 are connected by a line 18 for transmitting a test signal in a closed loop from the microprocessor 2 through the internal data transfer bus 6, then through the first controller 7 of the 200/500, 200AR protocol, the first galvanic isolation unit 10 and the first loop control and switching unit 11 to the additional loop monitoring and switching unit 14, then through the additional galvanic isolation unit 13, additional protocol 8 controller 200/500, 200AP, internal bus 6 for transmitting data to microprocessor 2.

Interest in address-analog systems is steadily increasing. To date, systems of this class are the most effective in detecting fire. Address-analog equipment operates according to the 200+ protocol. Address-analog systems built on the basis of the 200+ protocol are recognized as the most intelligent and technically advanced.

The use of these systems allows to increase the number of devices in the address-analog loop, reduce the response time of the system, provide visual monitoring of the status of the detectors and the short-circuit isolator integrated in the detector, provide multi-stage activation of sirens and synchronize them via the address-analog loop, and reduce cable costs.

The new 200AP protocol is an extended version of the 200+ protocol. The 200AP protocol allows you to connect up to 159 detectors and up to 159 addressable devices to the system, thereby allowing the end user to save on cable, additional extenders for the address-analog loop, etc.

The 200AP protocol contains a sub-addressing mechanism that increases the capacity of the address-to-analog loop and allows each channel of multi-channel devices to be controlled separately. The essence of this mechanism is as follows: in addition to the main address occupied by the device, for example, a combined siren in the address space of the modules, each channel (sound and light) is also assigned a sub-address, which can be accessed by command from microprocessor 2.

The 200AP protocol also contains an “interrupt” function, which allows the system to respond as quickly as possible to an emergency situation. For example, when the current value of the monitored parameter exceeds the value of the programmed threshold of the device, the device generates an “interrupt” signal. After receiving such a signal, the panel will know that the device in the address-analog loop has changed its state, after which the address of the specified device is detected. From the moment the device status changes to the moment the control devices are activated, it takes no more than 3 seconds, it doesn’t matter how many devices are connected to the analog-address loop and what address the activated device has. The thresholds of the devices are programmed during the commissioning of the system.

In FIG. 2 shows an embodiment of an address-analog loop control module 1, in which module 1 contains a microprocessor 2, additionally connected via an internal data bus 6 with two additional controllers 8, 8 ’of the 200/500, 200AP protocol.

Additional controllers 8, 8 'of the 200/500, 200AP protocol are connected to addressable detectors of the second and third address-analog loop 12, 12' of addressable devices through additional blocks 13, 13 'of galvanic isolation and additional control and switching blocks 14, 14' of additional addressable -analog loops, respectively. Additional blocks 14, 14 ’control and switching of loops connected to the microprocessor 2 lines 15 and 17, 17’ communication to transmit information about the status of one of the address-analog loops 12, 12 ’.

The first loop control and switching unit 11 and additional loop control and switching units 14, 14 'are connected by lines 18, 18' for transmitting a test signal in a closed loop from the microprocessor 2 via the internal data transfer bus 6, then through the first controller 7 of protocol 200 / 500, 200АР, the first galvanic isolation unit 10 and the first loop control and switching unit 11 to additional loop control and switching units 14, 14 ', then through the additional galvanic isolation units 13, 13', additional controllers ry 8, 8 'protocol 200/500, 200AR, the internal data bus 6 to a microprocessor 2. The work module 1 (FIG. 1) controls addressable loops as follows.

Closed-loop data transmission inside module 1 of the analog-address loops allows diagnosing the main blocks of the module. The microprocessor 2 through the CAN interface 19 and the controller 20 of the CAN interface is configured to receive information about the status of external controlled and controlled devices, as well as to issue the results of self-diagnosis of module 1.

CAN 19 interface is designed to organize serial, highly reliable and inexpensive communication channels in distributed control systems. This interface has a protocol that supports the ability to locate several leading devices on the trunk and provides real-time data transfer.

CAN 19 has high noise immunity due to error correction. Data transmission is carried out by frames, which are accepted by all network devices. The identifier describes the contents of the data packet and is used to determine the priority when trying to transmit multiple devices simultaneously. The data transfer speed is selected based on the distance, the number of subscribers in the network and the capacity of the communication line. It is set according to the program and can range from a dozen Kbaud to 1 Mbaud.

The CAN interface standard defines data transfer regardless of the physical layer, i.e. The communication channel can be anything, for example, a radio channel or optical fiber. However, in practice, the CAN interface usually means a network with a physical communication channel in the form of a differential pair of wires.

CAN 19 interface, being an additional digital interface for communication with external devices, provides data transfer via data bus 4. If the exchange via data bus 4 stops, the microprocessor 2 transmits via CAN 19 information about the lack of communication with the external module 5 of the processor, for example, to an external diagnostic console 21.

The use of CAN 19 allows for reliable real-time data transmission for a wide class of devices - diagnostic consoles, industrial computers, input-output devices. Information on the results of self-diagnostics and diagnostics of address-analog loops is transmitted via CAN 19 to the diagnostic console to indicate the results.

The use of the 200/500, 200AP protocol allows real-time connection of addressable detectors and addressable external devices to module 1 for address-analog loop monitoring, and provides monitoring of the status of connected devices with the determination of their location at their address.
