Description

The utility model belongs to the class of regulatory and control systems of general purpose and can be used for research of automatic fire alarm systems and emergency control of building engineering systems.

The closest known analogue is the Stand for the study of microcontroller control systems (RF Patent No. 77477, MPK-G09B 23/18). A stand for studying microcontroller control systems, comprising a controller board on which a microcontroller is installed, a read-only memory device used for storing software, a read-only memory device used for storing operational data, and a data interface converter that is used to communicate with external devices, and also a group of user interface devices, consisting of a keyboard unit and an indication unit, a group of peripheral test and simulating devices c, consisting of a source of harmonic signals with adjustable amplitude and frequency, a source of pulse signals with adjustable frequency and duty cycle, a potentiometer and an RC link with variable parameters, as well as a switching field, the first group of outputs of which is connected to the outputs of the microcontroller, the second group of outputs is connected with conclusions of the specified user interface devices, and the third group of conclusions is connected to the conclusions of the specified test and simulating devices, while the conclusions belonging to all three of these memory, is configured to interconnect in predetermined combinations using removable conductive jumpers and connect to external contact probes stands and external instrumentation.

The disadvantage of this device is the use of only one controller and the absence on the equipment stand of automatic fire alarm systems and emergency control of building engineering systems: sensors, detectors and actuators.

The problem solved by the proposed utility model is to provide the ability to simulate the operation of automatic fire alarm systems and emergency control of building engineering systems using devices (controllers) of various manufacturers and increase the practical significance and visibility of modeling by introducing the equipment of automatic fire alarm systems and emergency control of building engineering systems in the stand. The solution to this problem is important to ensure the possibility of checking the compatibility (interoperability) of controllers of various manufacturers working in one automatic fire alarm system and emergency control of building engineering systems and facilitating work with laboratory equipment.

The essence of the technical solution consists in the introduction of two additional controllers, a temperature sensor, a temperature sensor simulator, a smoke sensor, a smoke sensor simulator, an acoustic fire detector, a light indicator, a damper drive, an elevator simulator, a door lock simulator.

In fig. 1 shows a block diagram of a utility model.

The research laboratory stand for simulating automatic fire alarm systems and emergency control of building engineering systems includes an operator's computer (1), three controllers (2-4), a temperature sensor (5), a temperature sensor simulator (6), a smoke sensor (7 ), a smoke detector simulator (8), a sound fire detector (9), a light indicator (10), a damper drive (11), an elevator simulator (12), a door lock simulator (13). All of these devices are interconnected by a common data exchange bus (14). The programming of the controllers is carried out with the operator's computer via the data exchange bus using special software. The stand allows you to simulate the operation of automatic fire alarm systems and emergency control of building engineering systems using one, two and three controllers. The controller (s) involved in the simulation process receives signals from a temperature sensor, a temperature sensor simulator, a smoke sensor, and a smoke sensor simulator. In turn, the control signals from the controller (s) are sent to an audible fire detector, light indicator, damper actuator, elevator simulator, door lock simulator.

The presence on the multifunctional laboratory bench of the real elements of automatic fire alarm systems and emergency control of building engineering systems (temperature sensor, smoke detector, sound fire detector, light indicator, damper drive) simplify the work with laboratory equipment, increase the practical significance and visibility of modeling.

Thus, the proposed research laboratory bench simulating automatic fire alarm systems and emergency control of building engineering systems allows the research process to consider various options for building automatic fire alarm systems and emergency control of building engineering systems by introducing additional programmable logic controllers, and provides the ability to check the compatibility (interoperability) of devices of various manufacturers working in one automatic fire alarm system and emergency control of building engineering systems.
