The modular individual indicator performs periodic communication with the main control panel wireless communication module 120 of the main control panel 100 through the internal individual indicator wireless communication module 210, and transmits the power state, communication state, etc. in normal times. In addition, when an emergency situation occurs, it receives the direction indication, broadcasting mode, and contents from the main control panel and serves as an indicator to inform the emergency evacuation route. When communication operations such as transmission, reception, and reception standby state are prolonged, power consumption increases, and since the constant power configured independently from the outside cannot supply power to individual indicators for the desired lifetime, it is necessary to optimize this. For this purpose, it is possible to optimize the constant power lifespan of the individual indicator 200 while the individual modular indicator changes the communication operation by reflecting the change in the number of users around the indicator during normal times. That is, the individual indicator wireless communication module communicates with the main control panel wireless communication module at regular intervals.

Surrounding conditions can consider the number of users, and when there are many users, the individual indicator wireless communication module spends most of one cycle time of the set communication cycle operating time so that the emergency situation can be entered immediately in case of an emergency situation. Power consumption due to communication load can be optimized by keeping most of the 1 cycle time of the set communication cycle of the indicator wireless communication module in the OFF state.

During the above operation time, the individual indicator wireless communication module transmits regular power and communication status to the main control panel wireless communication module, and then maintains the reception standby state to receive the accident occurrence signal broadcast from the main control panel wireless communication module only in an emergency. have. The emergency signal generated while the individual indicator wireless communication module is OFF can be received in the next communication cycle.

The communication period (C) is set in the individual indicator wireless communication module 210, the operating time (A) of the individual indicator wireless communication module can be set in the timer IC 220, and each set value is A/C for each group It can be set by reflecting the value. In general, since the communication period (C) is determined in advance and applied to the device, the operation time (A) of the individual indicator wireless communication module can be calculated by the predetermined period (C). As for the A/C value for each group, the A/C value for each group calculated by the group-by-group communication congestion calculation unit of the main control panel is transmitted through the A/C value output unit for each group of the main control panel, and through the A/C value input unit for each group of the individual indicator received and reflected.

Next, the timer IC 220 turns on the power of the individual indicator wireless communication module 210 (step S120). Accordingly, the individual indicator wireless communication module 210 starts a communication operation.

Next, the individual indicator wireless communication module 210 transmits the constant power and communication status signals to the main control panel (step S130).

Then, it enters into a reception standby state waiting for an accident occurrence signal response (step S140).

Next, it is checked whether or not an accident occurrence signal is received from the main control panel (step S150).

When it is checked that the accident occurrence signal is received in step S150, the individual indicator wireless communication module transmits the accident occurrence situation to the MCU (step S160).

If it is checked that the accident occurrence signal is not received in step S150, it is checked whether the elapsed operation time of the individual indicator wireless communication module is less than the set operation time A msec (step S170).

When it is checked that the elapsed time of operation of the individual indicator wireless communication module is less than A msec in step S170, the feedback is fed back to step S140, which is a signal response standby state.

If it is checked that the elapsed time of operation of the individual indicator wireless communication module is equal to A msec in step S170, the timer IC 220 turns off the power of the individual indicator wireless communication module to terminate communication (step S180).

Next, the timer IC 220 sets the communication module OFF state required maintenance time (CA) msec, which is the difference between the set communication period (C) and the set operation time (A), in which the time elapsed from the state in which the individual indicator wireless communication module is turned OFF It is checked whether or not it is the same as (step S190).

In step S190, if it is checked that the elapsed time in the state that the individual indicator wireless communication module is OFF has elapsed by the communication module OFF state required maintenance time (CA) msec, it is fed back to step S110, and if it is checked that it has not elapsed, the individual indicator wireless Until the elapsed time from the communication module OFF state becomes the required communication module OFF state holding time, the individual indicator wireless communication module continues to be maintained in the OFF state.

The first operation method of the variable communication operation operation algorithm is an active variable mode, and the operating time ratio of the individual indicator wireless communication module within a predetermined communication period of the individual indicator wireless communication module 210 (shown in FIG. 2) is measured around the individual indicator group. It is a variable method reflecting the changing number of users of A piezoelectric scaffold as shown in FIG. 8 is installed to calculate the congestion level for communication, and the individual indicators 200 around the piezoelectric scaffold are grouped together and according to the group-specific communication congestion class calculated through the corresponding piezoelectric scaffold, individual indicators for each group are wireless It is to set the operating time ratio (A/C) of the communication module 210 (shown in FIG. 2).

8 is a configuration diagram for explaining a piezoelectric scaffold installed for calculating the congestion level for communication.

Referring to FIG. 8 , a piezoelectric footrest 90 manufactured using a piezoelectric element is attached to a nearby floor within the range of an indicator group composed of a plurality of individual indicators. Electricity generated according to the number of steps of the number of people in the vicinity is amplified at a constant rate through the amplifier 91 and input to the step current amount check unit for each group of the main control panel 100 .

The piezoelectric footrest is made larger than the general stride length in order to ensure that the station users have no choice but to step on the piezoelectric footrest 90 without intentionally crossing it.

In this embodiment, the communication congestion level for each group is graded by the operator through the communication congestion level standard setting unit 512 (shown in FIG. 4) of the input unit 510 (shown in FIG. 4) provided in the main control panel 100. You can set the number and criteria. For example, by classifying the congestion level such as red, orange, yellow, green, and blue in the order of high congestion level to low congestion level, the congestion level for communication for each group can be checked on the screen displayed by the main control panel 100. .

The level of communication congestion for each group may be calculated based on the accumulated current of the foothold in the group. That is, the communication congestion level for each group may be calculated through the operation of Equation 1 below, and may be performed by the communication congestion level calculation unit 522 for each group in the operation unit 520 of the main control panel 100 .

[Formula 1]

Here, W1 is a weight for each indicator group.

At this time, whenever the calculated level of communication congestion for each group exceeds the standard value for each level set by the operator, the operating time ratio (A/C) of the individual indicator wireless communication module 210 (shown in FIG. 2 ) is determined accordingly, which is the main control panel It is broadcast as individual indicators by the A/C value output unit 534 (shown in FIG. 4) for each group in the communication output unit 530 provided in the 100 . Each of the individual indicators receives the group-specific A/C value input unit 614 (shown in FIG. 5) according to the group's operating time ratio (A/C), and the individual indicator wireless communication module determines the communication period (C) Communication operations such as transmission, reception, and reception are performed only as much as the operation time (A) within one cycle of the time period, and the remaining time (CA) is adjusted by the timer IC so that the individual indicator wireless communication module is in the OFF state. In addition, the color corresponding to the communication congestion level for each group is displayed on the main control panel screen.

9 is a graph for explaining the setting of an operating time ratio (A/C) of an individual indicator wireless communication module according to an example. In particular, an example in which the operating time ratio (A/C) of the individual indicator wireless communication module is set according to the communication congestion level is shown.

Referring to FIG. 9, when the congestion level for communication of a specific group exceeds the reference 1 among the reference values for each grade, the operating time ratio (A/C) of the individual indicator wireless communication module 210 (shown in FIG. 2) is set to 0.8, the standard When it exceeds 2, the operating time ratio (A/C) of the individual indicator wireless communication module 210 is set to 0.9, and when it exceeds the standard 3, the operating time ratio (A/C) of the individual indicator wireless communication module 210 is 1 can be set That is, when the degree of congestion is high, the operating time ratio (A/C) of the individual indicator wireless communication module 210 is set high, and the proportion of the time that the individual indicator wireless communication module is ON within one cycle of the predetermined communication period (C) increases. In other words, the waiting time for receiving an emergency signal is longer, so it is possible to immediately recognize whether an emergency has occurred, but power consumption due to the communication load increases.

On the other hand, the operation method of the individual indicator wireless communication module 210 according to another example is a schedule mode, and when the individual indicator wireless communication module 210 for each group operates according to the communication cycle, the operation of the individual indicator wireless communication module 210 is This is a method in which the time ratio (A/C) is set according to time. This method can be used when rush hour time such as commuting time is clear and the frequency change of passengers is clearly differentiated according to time.

10 is a graph showing the setting of an operating time ratio (A/C) of an individual indicator wireless communication module according to another example. In particular, an example in which the operating time ratio (A/C) of the individual indicator wireless communication module is set according to time is shown.

Referring to FIG. 10 , in the schedule time setting unit that may be provided in the input unit 510 of the main control panel 100 , criterion 1 is set to 8:00 am and criterion 2 is set to 10:00 am for individual indicators 200 of a specific group. If set, from 8:00 am to 10:00 am from the A/C value output unit (534, shown in FIG. 4) for each group of the main control panel 100, the individual indicator wireless communication module (210, shown in FIG. 2) A value with an operating time ratio (A/C) of 1 is broadcast to individual indicators, and each of the individual indicators receives the According to the A/C value for each group, the communication operation is performed only for the operation time (A) allocated within one period of the communication period (C).

On the other hand, if the standard 3 is set to 6 pm and the standard 4 is 8 pm, from 6 pm to 8 pm, the A/C value output unit 534 for each group of the main control panel 100 (shown in FIG. 4 ) The value of the operating time ratio (A/C) of the individual indicator wireless communication module 210 of 0.9 is broadcast to individual indicators, and each of the individual indicators is an A/C value input unit 614 for each group, as shown in FIG. According to the A/C value for each group of the user group received through

In addition, as it is implemented in the form of an independent module that does not affect the operating power system, it can be installed and operated simply in the existing station.

In addition, maintenance-related budgets can be reduced because it uses a long-life self-powered power supply rather than a rechargeable type, so maintenance is almost unnecessary and inspection is easy through power and communication status notifications.

In addition, since the communication operation is changed according to the change in the number of users around the indicator during normal times, the lifespan of the self-power supply can be maximized.
