On the other hand, if the CO level of at least one of the five remote controllers 300_6, ... 300_10 selected by the second setting coefficient (b%) in the process S300 is the risk level ( CO n1) is not detected in excess, the automatic combustion stop unit 130 performs a fifth process (S500 to S560).

The fifth process (S500 to S560) will be described in detail as follows.

As described above, the CO level of at least one remote controller (any one of 300_6, ... 300_10) among the five remote controllers 300_6, ... 300_10 selected by the second setting factor (b%) is the risk level (CO n1) ) is not detected in excess, the automatic combustion stop unit 130 is a fourth setting coefficient set to select the remote controller (300_1, ... 300_10) belonging to the proximity range to the combustion device 200 and the selected CO detection distance The CO level of all four remote controllers 300_1, ... 300_4 selected by Equation 4 for room number selection using the fourth setting coefficient (d%) to be within the proximity range by (d%) is When it is detected to exceed the caution level (CO n2) (S500), the combustion device 200 is automatically stopped from combustion (S510), and the CO concentration is lowered to determine that the cause of the CO detection is the CO leakage of the combustion device 200 After the CO warning is notified before the number of inspections (B = m, m is a natural number) elapses (S520) to check whether the After the combustion stop time (T2) to check whether it loses has elapsed (S530), it is determined whether the CO level of all remote controllers 300_1, ... 300_10 is detected as less than the safety level (CO n3) (S540) of the combustion device 200 Re-combustion is started (S550).

In this case, in the process S520, it is preferable to notify the CO warning to all ten remote controllers 300_1, ... 300_10.

In addition, as shown in FIG. 7 , when the total number of rooms N = 10, when the fourth setting coefficient d% is set to 40%, the automatic combustion stop unit 130 is The condition that satisfies the room number ≤ (10×40%), that is, all four remote controllers (300_1,… It is determined whether the CO level of 300_4) is detected as exceeding the attention level (CO n2).

At this time, the four remote controllers 300_1, ... 300_4 installed in the four rooms (Room 1, Room 2, Room 3, Room 4) L1, L2, L1, L2, It corresponds to L3 and L4.

In addition, the automatic combustion stop unit 130 generates an error (Error) before notifying a CO warning when the number of inspections (B = m) has elapsed (S510), and an error in all 10 remote controllers (300_1, ... 300_10) It is desirable to notify the occurrence.

In addition, the automatic combustion stop unit 130 after the combustion stop time (T2) has elapsed (S530), when the CO level of all the remote controllers 300_1, ... 300_10 is detected to be less than the safety level (CO n3), the inspection Count up the number of times (B = m) and start recombustion of the combustion device 200 (S540), and if the CO level of all the remote controllers 300_1, ... 300_10 is not detected below the safe level (CO n3), the The recombustion of the combustion device 200 is started without counting up the number of times of inspection (B = m) (S550).

If, in the S500 process, the CO level of all four remote controllers 300_1, ... 300_4 selected by the fourth setting coefficient (d%) is not detected as exceeding the caution level (CO n2), the automatic combustion stop unit (130) releases the CO warning notification when the CO level of all remote controls (300_1, ... 300_N) is detected to be less than the safe level (CO n3) (S560), CO warning notification to all 10 remote controls (300_1, ... 300_10) It is desirable to inform the release.

As can be seen from the above, in the present invention, during the combustion operation of the combustion device 200 using fuel such as gas or oil, the installation defect of the combustion device 200 or the influence of the external environment (eg, from the outside) Even if exhaust gas leakage occurs due to the removal of the exhaust tube that discharges the burned exhaust gas due to the impact applied by the Based on the detection distance, it warns the danger level (CO n1) or caution level (CO n2) detected by the remote controller (300_1,…300_N) or automatically stops the combustion device 200, so the combustion device 200 and the remote control According to the degree of proximity between (300_1, ... 300_N), it is possible to easily determine the occurrence of CO leakage of the combustion device 200 .

In addition, the present invention can prevent or solve the problem of frequent CO poisoning accidents for people or animals living indoors when indoor air is polluted due to CO detection.
