As shown in FIG. 1 , the complex signal detection controller 10 of the present invention includes a control unit 100 including a mode limiting unit 110 and a reading unit 120 .

In this case, the controller 100 may control the operation of the controller 10 and obtain a signal from at least one sensor among the plurality of sensors.

Specifically, the plurality of sensors may be of different types, and the controller 10 may simultaneously acquire all the composite signals generated from each of the plurality of sensors and execute each reading by a reading method according to the type of the signal.

Additionally, the controller 10 of the present invention includes an output that operates in response to the signal.

The mode limiting unit 110 limits a signal reading method to the first mode or the second mode, and the reading unit 120 acquires a measurement value based on the signal, and measures according to the first mode or the second mode read the value

In this case, the mode limiter 110, as shown in FIG. 1, further includes a switch, so that it is possible to set the read method to the first mode or the second mode according to the position in which the switch is in contact.

Specifically, the switch of channel 2 shown in FIG. 1 is located at the first point corresponding to the first mode, so that the reading unit 120 can read the signal obtained from the coin-type sensor, and the The switch is positioned at the second point corresponding to the second mode, so that the reading unit 120 may read a signal obtained from the film-type sensor 220 .

The control unit 100 of the present invention, when the reading unit 120 reads the measured value in the first mode, determines the first leak based on the measured value exceeding the first reference value, and the reading unit 120 When the measured value is read in the second mode, the second leak may be determined based on the measured value that is less than the second reference value, and the disconnection may be determined based on the measured value that exceeds the second reference value.

Specifically, the first leak and the second leak correspond to the occurrence of a leak event of a hazardous chemical, and the disconnection corresponds to the occurrence of a disconnection event in the connection between the sensor and the controller 10, the measured value, the first reference value and The second reference value may be a resistance value, and the signal may be data including the resistance value.

In one embodiment, when the first reference value is 0 Ω in the first mode, the reading unit 120 may detect a hazardous chemical leakage event in a section (0 to t1) in which the measured value does not occur, as shown in FIG. 2 . It can be determined as a safe situation in which no occurrence of have.

In another embodiment, the controller 10 in the second mode when the second reference value is 300Ω, as shown in FIGS. 3 and 4, the second leakage and disconnection according to whether the measured value corresponds to 300Ω can judge

Specifically, as shown in FIG. 3 , the reading unit 120 determines that the measured value less than the second reference value has occurred from the point in time t2 when the measured value is decreased, and the second corresponding to the leakage event of the hazardous chemical substance 2 leak can be determined, and as shown in FIG. 4 , from the point in time t3 when the measured value rises, it is determined that the measured value exceeds the second reference value to determine the disconnection.

In this case, when the measured value is the same as the second reference value or the difference value (the value obtained by subtracting the small value from the large value) with the second reference value is less than or equal to a preset value, the present invention The reading unit may determine that the measured value corresponds to the second reference value, and thus may be determined as a safe state in which a hazardous chemical leak event or a disconnection event does not occur.

The plurality of sensors includes at least one of a point type sensor 210 and a film type sensor 220, the point type sensor 210 generates a signal when a leak occurs, and the film type sensor 220 when a leak occurs It may be characterized in that the measured value is decreased, but a signal in which the measured value increases when a disconnection occurs is generated.

Specifically, the point-type sensor 210 is located at a point for monitoring the leakage of hazardous chemicals, and when detecting a leakage event of hazardous chemicals, generates a signal corresponding to the first leak.

Additionally, the controller 10 of the present invention may limit the mode limiting unit 110 to the first mode in response to a signal non-reception event.

Specifically, as shown in FIG. 1, in the case of channel 3, there is no signal to be acquired because there is no connected sensor, and since the switch is located at the first point, the control unit 100 determines that the reading unit 120 is The third channel is read in the first mode, and when the first reference value is 0, the first leak cannot be determined, that is, the reading unit 120 reads the channel to which the sensor is not connected. It may not be performed, or the reading may be performed in the first mode.

For example, as shown in FIG. 1 , when the film-type sensor 220 is dropped from the controller 10 while the reading unit 120 reads a signal in the second mode in the first channel, the control unit ( 100) may forcibly switch the signal reading method to the first mode for channel 1 to which the film-type sensor 220 is coupled.

Accordingly, the control unit 100 controls the mode limiting unit 110 to change the signal reading method to the first mode limiting unit 110 when a signal non-reception event occurs while the mode limiting unit 110 limits the signal reading method to the second mode. It can be fixed to limit the mode.

When the reading unit 120 reads the measured value in the second mode, the controller 100 may obtain a second reference value corrected based on the measured value according to a preset time interval.

Specifically, as shown in FIG. 5 , the measured value forms a solid line graph, and the second reference value is corrected according to a preset time interval (eg, 14 minutes, 10 minutes, etc.) to form a dotted line graph. have.

In an embodiment, the second reference value of the first section (0:56:33~1:10:45) is the 2-1 reference value, and the second reference value of the second section (1:10:45~1:24:44) When the second reference value is the 2-2 reference value, the difference between the 2-2 reference value and the 2-1 reference value is equal to or less than a preset value, and the 2-2 reference value is the 2-1 reference value in the first section. It may be a corrected value corresponding to the measured value obtained at the time point (0:56:33) partitioned from the second section.

The control unit 100, when the event occurrence information corresponding to at least one of the first leak, the second leak and disconnection is obtained, the unique ID information and event occurrence information corresponding to the controller 10 to the manager terminal 20 Transmit, the output unit, the first leak, the second leak and disconnection, when at least one event occurrence information is obtained, performs a preset alarm, the alarm, including at least one of sound output, led lighting and vibration output It can be characterized as

With the above-described configuration, the manager corresponding to the manager terminal 20 can obtain the location information of the controller 10 that has generated event occurrence information based on the unique ID information, and according to the event type, At least one of a location access restriction and a response method may be determined.

When the reading unit 120 reads the measured value in the second mode, the control unit 100, if the corrected second reference value corresponds to a preset threshold value, as shown in FIG. 6 , the manager terminal 20 It may be characterized in that the unique ID information corresponding to the controller 10 and the generation time information of the second reference value corresponding to the limit value are transmitted.

The control unit 100 further includes a temperature sensor, obtains a temperature measurement value from the temperature sensor, corrects the measurement value based on a preset weight corresponding to the temperature measurement value, and sends the temperature measurement value to the manager terminal 20 . and transmitting a correction history corresponding to the temperature measurement value.
