Find out in detail in relation to the present invention. When the door of the artificial intelligence switchboard and automatic control panel 100 is opened, the inside is exposed to the external environment, and the external environment is different from the environmental conditions inside the artificial intelligence switchboard and automatic control panel 100, so each (temperature / humidity / arc / CO/vibration) detection sensor 100a may malfunction differently from when the door is closed. Therefore, it is possible to use the door open/close sensor 106 to ignore the information detected when the door is opened, but even when the door is opened, the switchboard continues to perform the given task without rest, and there is always an emergency situation. It is in a condition that can happen. Therefore, rather than ignoring all detected information and stopping operation, the degree of opening of the door, that is, the ignoring rate is set differently according to the opening angle, so that the state of the artificial intelligence switchgear and automatic control panel 100 can be monitored without rest. it is more preferable

Here, in order to simplify and clarify the description, the opening of the door is door opening; The open angle of the door for how much the door is opened is the door open angle; Measuring the door opening angle is door opening angle measurement; The detected information includes detection information; Ignoring detection information means ignoring detection information; The ratio of how large (large) the degree of ignoring the detection information (ignoring the detection information) will be expressed as the detection information ignoring rate.

In order to measure the door opening angle, the detection sensor 100a of the switchboard and automatic control panel 100 may further include a door opening angle measurement unit 120 (door opening angle sensor/detector). That is, the door open/close sensor 106 may include the door open/close angle measurement unit 120, or the door open/close sensor 106 may be separately provided with the door open angle measurement unit 120 and may be combined.

When the detection information performed by the door open/close sensor 106 is detected as door open, the door open angle measurement unit 120 immediately starts (starts) the measurement of the door open angle.

In proportion to the door opening angle measured by the door opening angle measurement unit 120, the size of the detection information ignoring ratio for the detection information of each (temperature/humidity/arc/CO/vibration) detection sensor is set to be proportional. Although this operation may be performed directly in the door opening angle measurement unit 120, each detection sensor 100a, and the control module 110, each detection sensor including the door opening angle measurement unit 120 It is more preferable to allow the collected information to be processed (calculated, learned) together in the artificial intelligence server 300.

Depending on the size of the detection information ignoring rate, the degree of ignoring the detection information varies, and the greater (or smaller) the detection information ignoring rate, the greater (or less) the sensed detection information is ignored. That is, the detection information ignoring rate means that all detection information is not ignored but a little is acknowledged, and the sensitivity to accept detection information can be lowered (or made insensitive), or the detection information can be partially discarded and only partially accepted. there is. Therefore, the manager checks the usual management experience and the state of the switchboard, etc., and directly sets the detection information ignoring ratio suitable for the field situation in proportion (or inverse proportion), or it can be provided to the artificial intelligence server 300 to perform prior learning. .

For example, as the door is opened, the door opening angle measurement starts (the door opening angle starts to be measured), and accordingly, the measured door opening angles (a1, a2, a3 .. . an) section is sensed (sensed, measured), and when a situation occurs in which detection information is detected by each (temperature/humidity/arc/CO/vibration) detection sensor after door opening, the measured door opening angle (a1, A2, a3...an) matched in (inversely) proportionally to the increase (or decrease) of the size and sequentially ignoring the detection information, that is, the matched detection information ignoring ratio (b1, b2, b3, b4 ... bn) is provided to be selected and determined.

The measured door opening angles (a1, a2, a3 ... an) may be defined and set as, for example, angle a1 is 30 degrees, a2 is 60 degrees, a3 is 90 degrees, and an is 180 degrees. The detected information ignoring ratio (b1, b2, b3, b4 ... bn) is, for example, b1 ignores 20% of detected information, b2 ignores 40%, b3 ignores 60%, b4 ignores 80%, and bn ignores completely. It can be defined and set to ignore, etc.

For each detection sensor, for example,

In proportion to the door opening angle measured by the door opening angle measuring unit 120, the size of the detection information ignoring ratio with respect to the detection information of the temperature detection sensor may be set to be proportional. For example, in the case of an environment or season where the outside temperature is higher than the temperature inside the switchboard, the sensitivity of the detection information of the temperature detection sensor can be corrected to be lowered by increasing the size of the detection information ignoring ratio in proportion to the door opening angle. In this case, that is, when the external temperature is low, the sensitivity of detection information of the temperature detection sensor may be corrected to be high.

In proportion to the door opening angle measured by the door opening angle measuring unit 120, the size of the detection information ignoring ratio with respect to the detection information of the humidity detection sensor may be set to be proportional. For example, in the case of an environment or season where the humidity outside is higher than the temperature inside the switchboard, the sensitivity of the detection information of the humidity detection sensor can be corrected to be lowered by increasing the size of the detection information ignoring rate in proportion to the door opening angle. In this case, that is, when the external humidity is low, the sensitivity of detection information of the humidity detection sensor may be corrected to be high.

In particular, the case of the arc detection sensor 103 is important, and the size of the arc detection information ignoring ratio with respect to the detection information of the arc detection sensor 103 is proportional to the door opening angle measured by the door opening angle measurement unit 120. can be set proportionally. The arc detection information ignoring rate, for example, when the conditions set by the manager are met, the arc sensitivity (sensitivity in response to the strength of the arc, or sensitivity recognized by counting the number of occurrences of the arc) is lowered (decreased) to operate This can be achieved by setting

Looking at it step by step,

A step of starting measuring the door opening angle as the door is opened (starting the door opening angle measurement) is included.

and determining whether the measured door opening angle is greater than 0 degrees and less than or equal to a1 (0<measured door opening angle<=a1). For example, it is determined whether the door opening angle is greater than or equal to 0 degrees and less than or equal to 30 degrees.

If the condition of the above step is met, a step of setting the detection information ignoring rate as b1 (the detection information ignoring rate = b1) is included. For example, the detection information ignoring rate is set to 20% (ignoring 20% and recognizing the remaining 80%). In the case of the arc detection sensor 103, 20% of the detected arc is ignored and 80% is recognized as an arc.

and determining whether the door is further opened and the measured door opening angle is greater than a1 and less than a2 (a1<measured door opening angle<=a2). For example, it is determined whether the door opening angle is greater than or equal to 30 degrees and less than or equal to 60 degrees.

If the condition of the above step is met, a step of setting the detection information ignoring rate as b2 (the detection information ignoring rate = b2) is included. For example, the detection information ignoring rate is set to 40% (ignoring 40% and recognizing the remaining 60%). In the case of the arc detection sensor 103, 40% of the detected arc is ignored and 60% is recognized as an arc.

and determining whether the door is further opened and the measured door opening angle is greater than a2 and less than a3 (a2<measured door opening angle<=a3). For example, it is determined whether the door opening angle is greater than or equal to 60 degrees and less than or equal to 90 degrees.

If the condition of the above step is satisfied, a step of setting the detection information ignoring rate as b2 (the detection information ignoring rate = b3) is included. For example, the detection information ignoring rate is set to 60% (60% is ignored and the remaining 40% is recognized). In the case of the arc detection sensor 103, 60% of the detected arc is ignored and 40% is recognized as an arc.

and determining whether the door is further opened and the measured door opening angle is greater than a3 and less than a4 (a3<measured door opening angle<=a4). For example, it is determined whether the door opening angle is greater than or equal to 90 degrees and less than or equal to 110 degrees.

If the condition of the above step is met, a step of setting the detection information ignoring rate as b4 (the detection information ignoring rate = b4) is included. For example, the detection information ignoring rate is set to 80% (80% is ignored and the remaining 20% is recognized). In the case of the arc detection sensor 103, 80% of the detected arc is ignored and 20% is recognized as an arc.

Of course, if the step goes further, the detection information ignoring rate can be set to 100%, that is, to ignore all.
