s31, when the real-time offset of the civil air defense door is between the early warning parameters (delta x1, delta y1 and delta z1) and the warning parameters (delta x2, delta y2 and delta z2), the processor outputs an early warning signal of normal offset of the civil air defense door;
s32, when the real-time offset of the civil air defense door is between the alarm parameters (delta x2, delta y2 and delta z2) and the fault parameters (delta x3, delta y3 and delta z3), the grading alarm processing module outputs the alarm signal of the deviation of the civil air defense door;
and S33, when the real-time offset of the civil air defense door is greater than the fault parameters (delta x3, delta y3 and delta z3), the grading alarm processing module outputs a fault signal that the civil air defense door influences the rail transit and needs to be stopped and repaired, and the rail transit is influenced and needs to be repaired at the moment.
The high-speed processor is used for accurate control, three-level alarm is carried out on the lifting angle state of the civil air defense door, and an early warning signal is sent out through normal deviation; abnormal deviation is not caused but the influence on the rail transit is not generated, and an alarm signal is sent out; the abnormal deviation affects the rail transit, sends a fault signal, is convenient to overhaul, adjust and remove faults, and can reduce the probability of misinformation in detail in a grading manner.
Further, for the convenience of identification, the alarming steps of the field alarming device are as follows:
s311, when the early warning signal is sent to the field alarm device, the field alarm device displays green lights and/or broadcasts the voice allowing passage or sends out discontinuous short-tone alarm signals;
s321, when the alarm signal is sent to the field alarm device, the field alarm device displays yellow light and/or broadcasts the voice allowing passage or sends out intermittent long and short sound alarm signals;
and S331, when the fault signal is sent to the field alarm device, the field alarm device displays red lights and/or broadcasts the voice of no passing or sends out intermittent long-tone alarm signals.
Through different audible and visual alarm signals, the lifting angle deviation state of the civil air defense door can be clearly known on site, the fault site can be conveniently found, the site inspection and maintenance can be conveniently guided, the maintenance efficiency is improved, and the maintenance cost is further reduced. The acousto-optic alarm device has the functions of error correction (acousto-optic simultaneous display, if the display result is consistent, the display is correct, if the display result is inconsistent, the display is wrong, so that the error correction is carried out), and the alarm reliability is improved (the acoustic or optical fault in acousto-optic can still give an alarm), the acousto-optic alarm step of the on-site alarm device is easy to realize, intelligent and efficient, easy to operate, free of preparation or remote calling of relevant civil defense door fault information materials, time and material cost are saved, and then the civil defense door is efficiently supervised and maintained.
The user side can make corresponding instruction scheduling or maintenance management according to the judgment result: for example, if the judgment result is a fault state, the train operation of the corresponding road section needs to be instructed and scheduled to stop, and maintenance personnel are dispatched to carry out maintenance, the reason for the lifting angle may be the fault of the jack and/or the hinge, and the maintenance personnel only need to carry out investigation and maintenance one by one; if the attitude sensor fails, the dispatching is required to be instructed to stop the vehicle running, and then maintenance personnel are dispatched to check, maintain and replace in time so as to avoid influencing train running or other accidents and recover normal traffic in time. The user side comprises the mobile terminal and the fixed terminal, so that the user side can conveniently know the state of the civil air defense door hanging angle in a fixed place such as a master control room, and can conveniently move and manage managers when the managers go out, faults and accidents can be prevented in advance, and the safety is improved.
The above description is only for the purpose of illustrating the preferred embodiments of the present invention and is not to be construed as limiting the invention, and any modifications, equivalents, improvements and the like that fall within the spirit and principle of the present invention are intended to be included therein.
