Description
Technical Field
The utility model relates to a real teaching field of instructing, concretely relates to conflagration automatic alarm and linkage simulation demonstration experiment platform.
Background
In the aspect of fire control field teaching, because the content of the fire alarm and fire control linkage system engineering technology is abstract, the students need to deepen the learning impression through practical operation, and the learning efficiency is improved. The training demonstration equipment which is associated with urgent needs provides required equipment and matched system configuration for training teaching.
The automatic fire alarm and linkage simulation demonstration experiment platform simulates and demonstrates the working principle and the process of an automatic fire alarm and fire-fighting linkage control system in a mode of combining an experiment demonstration board and a real object. The platform can demonstrate the working process of automatic alarm and fire-fighting linkage equipment after a fire disaster occurs by simulating fire alarm. The demonstration operation of the device can lead the students to master the basic constitution and the working principle of the fire fighting system.
The existing practical training platforms are divided into two types, namely vertical type and horizontal type. The lower part of the training platform is a bracket part, and the upper part of the training platform is a panel for mounting fire-fighting parts. The training platform can visually display the connection modes of the fire alarm linkage controller, the gas fire extinguishing control panel, the alarm unit, the acousto-optic and fire-fighting communication unit, the signal input unit and the gas fire extinguishing unit.
Generally, a vertical rack is easy to be used by teachers and students in classrooms for watching, and a horizontal rack is easy to be used by a plurality of groups of students for observing and measuring signals on a panel due to the fact that surrounding space is increased, so that students are familiar with the working principle and process of an automatic fire alarm and fire-fighting linkage control system. But the combination that current real standard platform can not be fine is in the same place, to vertical rack, needs the student to fire extinguishing system experiment operation after the mr gives a lesson, because the rack overall dimension is bigger, and the student operation of being not convenient for of upper portion in measurement panel upper portion and the both sides also has the restriction to the student's quantity of studying around the experiment rack moreover, makes partial student can not effectively observe the system operation process. For the horizontal rack, each system on the panel is convenient for operate, has also increased actual measurement student number, but is not very convenient to mr's lecture, because it is horizontal, the teacher only stands around the rack and listens to class when lecturing, and outer student listens to the effect very not ideal like this. If two sets of the electric heating device are used simultaneously, the use cost is increased, the practicability is low, and the flexible operation is not convenient.
And the easy accumulation dust in the rack use, be the electricity between each fire control part on the rack, the dust can lead to circuit failure, makes the unable normal operating of system or to host computer conveying error report, influences normal teaching, reduces student's learning quality and efficiency.
Chinese patent (CN207993277U) discloses a real teaching demonstration board of instructing of fire extinguishing system, including fire alarm linkage controller, gaseous fire control panel, alarm unit, reputation fire control communication unit, signal input unit, bus linkage control unit, multi-thread linkage control unit, gaseous fire extinguishing unit, this patent can demonstrate fire alarm and linkage system's operation process and principle, but this teaching demonstration version can not give the concrete structure of demonstration version platform, and this demonstration version platform does not have dustproof function, can't guarantee the effective operation of system.
