The specific embodiment
Fig. 1 is the block diagram of the structure of demonstration semaphore control system of the present invention.As shown in the figure, signal control setup 1 has signal lamp control part 2, power cycle test section 3 and lamp current test section 4, and it can control the signal lamp 8 with the signal electric lamp bulb 7 that is provided with filament 5 commonly used and subsequent use filament 6.Signal lamp control part 2 so that the instruction that signal lamp 8 is lighted/extinguished as lamp control input, control by the voltage of signal lamp source of AC 9 outputs it being supplied to signal lamp 8, thereby the lighting/extinguish of control signal lamp 8.Power cycle test section 3 for example is made up of photoelectrical coupler, and just often, the power cycle of detection signal lamp source of AC 9 is to be sent to signal lamp control part 2 with the power cycle signal.Lamp current test section 4 detects the lamp current that is supplied to signal lamp 8 from signal lamp control part 2, so that the lamp current detection signal is sent to signal lamp control part 2 just often.
Below, the work during to the signal control setup 1 control signal lamp 8 through having said structure describes.
At first,, explain that the filament commonly used 5 of electric lamp bulb 7 does not blow, whole actions just often with reference to the time diagram of Fig. 2.
A-c cycle be supplied to signal lamp control part 2 from signal lamp source of AC 9 is under the situation of 50Hz, and the power cycle Tp that detects through power cycle test section 3 is 20ms.Power cycle test section 3 is according to the alternating-current voltage/AC voltage that is supplied to signal lamp control part 2 from signal lamp source of AC 9, and the power cycle signal of the square wave of power cycle Tp is sent to signal lamp control part 2.Signal lamp control part 2 detects the rising or the decline of the power cycle signal that sends, and with predefined power cycle Tp contrast to confirm the alternating-current voltage/AC voltage of supplying with from signal lamp source of AC 9 normal, promptly from 9 normal supplies of signal lamp source of AC alternating-current voltage/AC voltage.Afterwards, control is connected/cut off to signal lamp control part 2 at the power cycle signal that sends from power cycle test section 3 just often according to the lamp control input from not shown interlock logic device output, to the lamp control output that is supplied to signal lamp 8.When cutting off this lamp control output, if the lamp current signal that sends from lamp current test section 4 cuts off, then signal lamp control part 2 judges that not detecting filament 7 commonly used blows.In addition, normal at the power cycle signal, lamp control input is connected and is supplied to the lamp control of signal lamp 8 and exports when connecting, and under the situation that the lamp current detection signal that sends from lamp current test section 4 is connected, judges that not detecting filament 7 commonly used blows.
Below, with reference to the time diagram of Fig. 3, the action when switching with the system of the signal lamp source of AC 9 that receives electric system of any reason switching signal lamp source of AC 9 describes.
Generally speaking, make signal lamp source of AC 9 realize redundancyization, and signal control setup 1 is supplied power from the system of selecting through switching part with mode by the power supply of 2 systems.When switching this system, the power supply moment disconnection of power supply Ts switching time can take place.This power supply Ts switching time is generally about 150ms.Power supply moment when the system of this signal lamp source of AC 9 is switched is when breaking off, and is as shown in Figure 3, is sent to the power cycle signal cut of signal lamp control part 2, and the lamp current detection signal also cuts off.For signal lamp control part 2; Power cycle signal sending from power cycle test section 3 is normal; And, show the signal lighted and lamp control output be sent under the state of signal lamp 8 sending, if the power cycle signal cut and the lamp current detection signal that send from power cycle test section 3 cut off as lamp control input; Then calculate the time length of dissengaged positions; Ts switching time contrasts with predefined power supply, and when the time length of the off-state of lamp current detection signal was the power supply Ts switching time left and right sides, the system of decision signal lamp source of AC 9 was switched.Afterwards, signal control part 2 is under the state of connection in the lamp control output of sending into signal lamp 8, and power cycle signal and lamp current detection signal cut off, and when switching in the system of decision signal lamp source of AC 9, judges that not detecting filament 7 commonly used blows.And,, judge that signal lamp source of AC 9 produces unusually, and show its meaning of output during the time than power supply Ts switching time overshoot at the power cycle signal and the time length of the off-state of lamp current detection signal.
Below; Time diagram explanation with reference to Fig. 4: the alternating-current voltage/AC voltage be supplied to signal control setup 1 from signal lamp source of AC 9 is normal; The lamp control of sending into signal control part 2 is input as and shows the signal of lighting; When the lamp control output of sending into signal lamp 8 from signal control part 2 is connected, the action when filament 5 commonly used blows.
Carrying out lamp control output through signal control part 2 so that filament 7 commonly used is supplied power; Filament 7 commonly used blows; If detect filament blow commonly used through yarn break detector 10; Then after through the repair time Td that forms by capacitor C with the coils from parallel connection of coils of the output relay FDR of yarn break detector 10, output relay FDR reinstatement.Select the capacity of capacitor C in advance so that the repair time Td of this output relay FDR is longer than power supply Ts switching time.
Therefore; If signal control part 2 at the power cycle signal that sends from power cycle test section 3 just often; Under the state of the lamp control output of connecting and be supplied to signal lamp 8 from the lamp control input of interlock logic device output; Become cut-out from the lamp current detection signal of lamp current detector 4 inputs from connection; Then calculate the time length of lamp current detection signal dissengaged positions; The time length and predefined power supply Ts switching time of the dissengaged positions of the lamp current detection signal of the repair time Td of output relay FDR and calculating are contrasted; After if the time length of the dissengaged positions of the lamp current detection signal when the lamp current detection signal is connected surpasses power supply Ts switching time and reaches the repair time Td of output relay FDR, confirm that at once the power cycle signal is normal and carry out lamp control output, judge that then the signal electric lamp bulb 7 of signal lamp 8 switches to subsequent use filament 6 from filament 5 commonly used.Afterwards, judge to have the detection of blowing of filament 5 commonly used, the expression signal of its meaning of expression be delivered to the interlock logic device, and with its storage until resetting by blowing restore instruction etc.
Like this; In the output relay FDR of yarn break detector 10, keep the slow release characteristic of repair time Td, if detect the power cycle signal just often, under the state that carries out lamp control output in signal control part 2; Cut off from the lamp current detection signal of lamp current detector 4 inputs; Then calculating should break time, the time length of the dissengaged positions of lamp current detection signal surpass power supply Ts switching time and with the output relay FDR of yarn break detector 10 in repair time Td when consistent, detect and use always after filament 5 blows; Between the signal lamp control part 2 of signal control setup 1 and signal lamp 8 only through 1 couple of feed cable 11a; 11b connects, and between signal lamp 8 and signal lamp control part 2, needn't be provided for the control cable of reparation contact condition of output relay of the yarn break detector 10 of inputted signal light 8, simultaneously; Needn't be provided with the input circuit that blows detection signal inputted signal light control part 2, thereby can obtain the signal control setup of high economy from signal lamp 8.
