Embodiment

As shown in Figure 1, the centralized fault alarm of a kind of LED teleseme unit, comprise an AT89S52 monolithic microcomputer kernel control chip, be connected with alarm cell controller and LED alarm lamp on the kernel control chip, wherein the effect of alarm cell controller is the inquiry that is used to that various parameter values are set and the teleseme working current is provided; Described fault alarm unit also comprises teleseme current monitoring module, teleseme lamp position voltage acquisition load module, watchdog module, RS485 network communication module, hummer module and the switching value alarm output module that is connected with kernel control chip, is connected with the LED teleseme between described teleseme current monitoring module and the teleseme lamp position voltage acquisition load module.

Described teleseme current monitoring modular circuit schematic diagram as shown in Figure 2, this module is by sealing in the output voltage loop line in current sensor, but working current with regard to the acquired signal machine, the voltage signal of current sensor output supplies single-chip microcomputer computing and processing by the AD conversion of TLC1543 chip, be converted into current value, an alarm unit is made up of eight current detection modules altogether, to realize the collection to eight telesemes, has only drawn one the tunnel among the figure.

Described teleseme lamp position voltage acquisition load module circuit theory diagrams as shown in Figure 3, this module is by the switching of outside relay, when SLD1 or SLD2 end input voltage, shunting action by two resistance, the pressure stabilization function of electric capacity, pass through the photoelectricity transformation of TLP521 optocoupler again, the DYSL1 of output and DYSL2 signal are by the parallel serial function that is converted into of shift register integrated package, output is for the single-chip microcomputer calculation process, just can distinguish the fault of three lamp positions of each frame teleseme, this part also is made up of eight voltage acquisition modules altogether, to realize collection, only drawn one the tunnel among the figure to eight telesemes.

Described RS485 network communication module circuit theory diagrams as shown in Figure 4, the impedance matching of the control that this part sends and receives by Q2 and R64, R65, R66 and the transient voltage of three TVS suppress ability, make 485 communications stable more and reliable, antijamming capability is strong.

Described switching value alarm output module circuit theory diagrams as shown in Figure 5, the switch of the photoelectricity buffer action control 12V relay of this module by the TLP624 optocoupler is when producing when reporting to the police relay adhesive, output alarm signal.

Described watchdog module circuit theory diagrams as shown in Figure 6, the monitoring of this module by watchdog chip X25045 can prevent effectively that program from entering endless loop, when program enters endless loop, this chip produces a REST reset signal, makes program restart operation, has system's self-recovering function.
