Fig. 1 is a block diagram of an alarm circuit related to the first embodiment of the present invention, and Fig. 2 is a block diagram of a train approach alarm device. As shown in FIG. 1 and FIG. 2, the train alarm device related to the embodiment of the present invention is that when the main switch (SWM) is changed from the off state to the on state, a plurality of light emitting diodes (LEDs) are obtained. ) The alarm display 10 is a device that sequentially lights up in a predetermined sequence. The sequence of the alarm display 10 is indicated by arrows in Fig. 2. ‘Alarm display -9- (7) 1235121 1 0 is arranged along the edge of the platform on the platform of the station to remind the passengers that the train is about to enter the station in order to light up in order to guide the passengers safely. In contrast to the plurality of alarm displays 10, a plurality of alarm display circuits 20 and a plurality of alarm display circuits 20 are arranged on a 2-core 1-circuit line in a multi-cascade connection. The alarm display circuit 20 applies the terminal voltages of the return lines to the alarm display 10 in a predetermined order. In the embodiment of the present invention, the terminal voltage is applied in a direction from the alarm display circuit 20 on the left side (front side) in FIG. 2 to the alarm display circuit 20 on the right side (second side) in FIG. 2. The terminal voltage of the return line is equivalent to the power supply voltage added between the IN terminal and the GND terminal of the return line. The plurality of alarm display circuits 20 are connected in multiple cascades on one line along the edge of the platform of the station platform, each of which has a first timer T1 and a first switch S W1 operated by the timer, And, the second timer T2, and the second switch SW2 that operates in response to the timer. The alarm display circuit at the front of the multi-stage alarm display circuit and the front display of the next stage 20 are electrically connected to the next-stage alarm display circuit 20. The terminal voltage of the return line has a configuration that can be applied to the first timer T1 of each alarm display circuit 20. In addition, the terminal voltage is a configuration that can be applied to the in-line connected alarm display 10 and the first switch SW1. The first switch SW1 is such that when the main switch SWM is turned on, the terminal voltage is applied to make the first 1 When the timer starts to operate, the previous operation is maintained to maintain the ON state when the main switch SW1 is turned off. 'The terminal voltage can be applied to the alarm display 1 0, from the first timer τ1 -10- (8) 1235121 After the set time of 11 starts, the contact will change from the open state to the closed state. The first timer T1 is reset when the main switch SWM is turned off and the terminal voltage is removed. The second switch SW2 between the alarm display circuit 20 of the previous stage and the alarm display circuit 20 of the next stage is a device that operates by the second timer T2, and is the first timer of the alarm display circuit 20 of the previous stage. When the timer T1 starts to operate, it is in the off state. After the first timer T1 starts to operate, after a set time t2, it will change from the off state to the on state. The terminal voltage is applied to the first timer T1 of the secondary alarm display circuit 20. The contact made up of the above. After the second switch S W2 is turned on in sequence after the alarm display 10 is turned on, the main switch S WM is turned off, and the second timer T2 is reset to the off state when resetting. The first timer T 1 is also switched on the alarm display 10 After the sequence lighting is completed, it is reset by turning off the main switch SWM, and it is turned on. Next, the effect of this embodiment will be described. As the train approaching alarm device is, a plurality of alarm display circuits 20 are connected in a cascade on one line, following the direction from the alarm display circuit 20 of the previous stage to the alarm display circuit 20 of the second stage. The structure of sequentially applying the terminal voltages of the return lines allows the plurality of alarm displays 10 to light up in a predetermined order. Therefore, it is not necessary to configure one loop for each alarm display 10, and it is not necessary to configure a power supply for each alarm display circuit, which reduces operation time and labor. In addition, since it has a simple structure in which a plurality of alarm display circuits are connected in cascade on one line, the number of parts can be reduced and costs can be reduced. Figure 3 is a timing diagram of the alarm display circuit. -11-1235121 (9) Before the plurality of alarm displays 10 are started, all the second switches SW2 are turned off. The first switch SW1 of each alarm display circuit 20 is also turned on. When the main switch s WM (the main controller SWM shown in Figs. 2 and 3) changes from the off state to the on state, the terminal voltage of the return line is applied to the first timer T1 of the alarm display circuit 20 in the previous section. The first timer T1 of the alarm display circuit 20 in the previous stage is started to operate. At this time, the second switch SW2 is turned off, and the terminal voltage is not applied to the first timer T1 of the alarm display circuit 20 on the secondary side. The terminal voltage of the return line is applied to the first timer T1 and the second timer T2 of the alarm display circuit 20 at the previous stage, so that when the first timer of the alarm display circuit 20 starts to operate, the first switch SW1 of the alarm display circuit at the previous stage is maintained. On, but on. In addition, after the first switch SW1 of the alarm display circuit 20 in the previous stage starts to operate after a set time t1, the first switch SW1 of the alarm display circuit 20 in the previous stage changes from the on state to the closed state, so that the alarm of the alarm display circuit 20 in the previous stage alarm The display 1 〇 goes off 〇 The second timer is to start operation when a voltage is applied. It is turned on after 12 hours after the setting. It is the second between the alarm display circuit 20 in the previous stage and the alarm display circuit 20 in the next stage. The switch SW2 changes from the off state to the on state, and applies the terminal voltage to the first timer T1 of the alarm display circuit 20 in the next stage. The terminal voltage is applied to the first timer T2 of the alarm display circuit 20 of the next stage, and the first timer of the alarm display circuit 20 of the second stage starts to operate. '-12- 1235121 (10) 1 The switch SW1 is on, and the alarm display 10 associated with the alarm display circuit 20 in the next stage is applied with a terminal voltage and lights up. As in this mode, the terminal voltage is sequentially applied in the direction from the alarm display 10 associated with the alarm display circuit 20 in the previous stage to the alarm display 10 associated with the alarm display circuit 20 in the subsequent stage. The system turns on the alarm display 10 in the predetermined order from the left alarm display 10 to the right alarm display 10. Use the set time 11 of the first timer T1 to set the time from when the alarm display 1 goes on, and use the set time t2 of the second timer to determine the alarm from the previous display 10 to the next alarm Time difference until display 1 〇 lights up. That is to say, in the front and rear stages, the time setting of the alarm display 10 can be changed from turning off until the next stage lights up. When plural alarm displays 10 are flashed in a predetermined order, the lighting time and lighting can be changed. The interval between the lights can make the flicker frequency change. For example, the front and rear alarm displays can be turned on repeatedly, or conversely, after the front section goes out, the rear section is turned on after a short period of time. The lighting time itself can be changed using the set time 11 of the first timer. . After the sequential flashing of the plurality of alarm displays 10, the main switch SWM is turned off, the terminal voltage is 0, the first timer T1 and the second timer T2 are reset, and the first switch SW1 is changed from the off state. In the on state, the second switch SW2 is changed from the on state to the off state, and the -13- (11) 1235121 is ready for the next blinking of the alarm display 10. Figure 3 shows that the 1N side of the input terminal voltage loop is turned on, the first switch SW1 is turned on, and the alarm display 10 is turned on. After a set time of 11, the first switch s W1 is turned off. However, the second switch is turned on due to the set time t2 of the second timer T2 shortly after the turn-off. Therefore, the return side OUT of the output terminal voltage is turned on. Fig. 4 is an example of a timing chart showing a train approaching alarm device, in a case where the set time t2 of the second timer T2 is longer than the set time t2 of the first timer T1. As can be seen from FIG. 4, after the alarm display 10 in the previous stage is turned off, the alarm display 10 in the next time after the time difference between the set time 11 and the set time t2 is turned on. In addition, although the embodiment shows that a plurality of alarm displays 10 are connected in cascade on two cores and one circuit, as shown in FIG. 5A, three cores and one circuit can also be used to connect the plurality of alarm displays. Alarm display. Therefore, for example, when the station platform is extremely long, a plurality of alarm displays 10 are regarded as one block, and a plurality of blocks 1, 2, ... are continuously arranged on the ground edge of the station platform. The blocks light up in sequence at the same time. [Effects of the Invention] The use of the train approach alarm device related to the present invention has a plurality of alarm display circuits corresponding to a plurality of alarm displays, and the plurality of alarm display circuits are connected in a cascade in multiple stages on a single line. -14- (12) 1235121 are sequentially applied to a plurality of alarm display circuits, even in the case of the number of lighting units or alarm displays, as long as they are sequentially connected on a single line, no large power wiring is required Waiting time and manpower, so even in the case of additional installation of the existing station platform, roads, etc., compared to the overall additional installation costs, the engineering costs required for the installation, wiring, piping, etc. of the machine The proportion is also extremely low. In addition, since the overall structure of the device is simple, costs can also be reduced.
