The invention provides an infrared awakening automatic detection device for a three-phase electric energy meter, which comprises an infrared light-emitting module, an inclination angle adjusting module, a supporting module, a detection module and a control module, and is combined with a figure 1.
The infrared light emitting module is used for emitting infrared light. Comprises a plurality of infrared light emitting diodes 1 which are arranged and fixed on a mounting plate 2. The mounting plate 2 is a wood plate, and the back of the mounting plate leads out a wiring 3 of the infrared light-emitting diode 1. The mounting panel upper portion sets up protection casing 4 and outwards stretches out, the material of protection casing 4 is transparent ya keli.
The inclination angle adjusting module is used for adjusting the inclination angle of the infrared light emitting module, so that the infrared light emitting module is over against the infrared receiving unit of the three-phase electric energy to emit infrared light. The inclination angle adjusting module comprises a transmission shaft 5 arranged at the bottom of the mounting plate and a first servo motor 9, wherein the first servo motor 9 drives the transmission shaft 5 to adjust the inclination angle of the mounting plate, and the inclination angle is locked by screwing a fastening bolt 8 of the transmission shaft.
The infrared light emitting module is supported to a set height through the supporting module and moves to a set position. The support module comprises a support main body 6 and a jacking mechanism 7. The universal wheel 6-1 is arranged at the bottom of the support main body 6, the steering mechanism has a 360-degree steering function, can randomly change working environments and places, and has a brake stabilizing function. The support main body 6 is also used for fixing the jacking mechanism 7, the power supply adapter plate 10 and the control module, and can also be used for fixing the detection module. The support main body 6 can be provided with a configuration block 6-3, and the balancing weight 6-3 can ensure that the system keeps balance when encountering sudden external force and in the advancing process.
The jacking mechanism 7 comprises a bottom plate 7-1, a second servo motor 7-2, a motor transmission mechanism 7-3 and two support arms 7-4. The second servo motor 7-2 is arranged on the table top 6-2 of the support main body 6 and is fixed through a servo motor fixing bolt 7-4; the two support arms 7-4 are connected to the bottom plate 7-1 through the motor transmission mechanism 7-3 to drive the bottom plate 7-1 to rotate, the lower ends of the two support arms 7-4 are connected with the driving bottom plate 7-1, and the upper ends of the two support arms are connected to the bottom of the mounting plate. The jacking mechanism 7 realizes the adjustment of the angle of the infrared light-emitting module in the horizontal direction.
In one embodiment, a height adjustment mechanism may be provided to adjust the height of the infrared light emitting module.
The detection module detects whether the three-phase electric energy meter is awakened or not. After the three-phase electric energy meter is awakened, the liquid crystal screen can be lighted once every 0.2 seconds, and the sequence is as follows: 1) yellow 2) green 3) blue. The detection module detects light emitted by the liquid crystal screen and sends the light to the control module for judgment. The detection module comprises a plurality of photodiodes, and with reference to fig. 2, a yellow filter is arranged on part of the photodiodes, so that yellow light can pass through, be detected by the photodiodes, and be sent to the control module; the same part of the photodiode is provided with a green filter, so that green light can pass through and be detected by the photodiode; some photodiodes are provided with a blue filter so that blue light can pass through and be detected by the photodiode.
The control module controls the first servo motor 9 to adjust the angle and controls the second servo motor 7-2 to adjust the height; and receiving a current signal sent by the photodiode, and judging whether the current signal is in a correct sequence. The input pin stored in the control module corresponds to the color type of received light, and when the signal of the diode is received, the corresponding light color is searched. And judging the sequence according to the receiving time, judging the detection result after finishing the sequence judgment, emptying the currently stored color and sequence, and judging the next three-phase electric energy meter.
And judging whether yellow light, green light and blue light are included, if so, indicating that the awakening function of the three-phase electric energy meter is normal. In some cases, there may be a case that the detection of the three-color light is incomplete, for example, due to a transmission time error and a difference in response speed of each three-phase electric energy meter, the detection module flickers to blue light after awakening, in this case, after detecting the blue light, the detection module waits for 0.2s, and then the detection module detects yellow light → green light → blue light again, which indicates that the awakening function is normal, and if the detection module waits for 0.2s, the detection module determines that the awakening function is abnormal, and outputs an alarm message. Also if green light is initially detected, wait 0.2s, and go to the next blinking cycle to detect again.
As shown in fig. 4, the output ends of each group of photodiodes with the same color filter are connected to the control module through the diodes, and are output to the main control chip after filtering and amplitude adjustment, corresponding to one pin of the main control chip, so that any photodiode can inform the main control chip when detecting an optical signal, and the pin of the main control chip is saved.
If no light is detected within 0.2s, it may be either not woken up or not detected, thus possibly causing a false alarm. To avoid false alarms, an auxiliary decision needs to be made. In one embodiment, an auxiliary judgment module is arranged, the auxiliary judgment module comprises a light emitting diode and a photodiode corresponding to a color filter, orange light is emitted, the orange light is received and converted into an electric signal by a plurality of corresponding additional orange photodiodes after being reflected by the three-phase electric energy meter, the electric signal is sent to the control module, and the control module judges that the three-phase electric energy meter exists. If no three-phase electric energy meter is arranged at the detection position, orange light cannot be reflected, and further the orange light cannot be detected and obtained by additionally arranging an orange photodiode. Therefore, if no light is detected within 0.2s, and the detection signal sent by the auxiliary judgment module indicates that no three-phase electric energy meter is arranged at the detection position, no alarm signal is output, and vacancy reminding information is output.
And if the signal of the sequence of yellow light → green light → blue light is not detected within 0.2s, judging that the awakening function is abnormal. Because various instantaneous interference light sources may exist in the environment, judgment is carried out through the three-color light source and the light emitting sequence, and misjudgment is avoided. In one embodiment, if there is less interference in the environment, any two lights can be detected and the correct sequence can be used to determine that the wake-up function is normal.
Furthermore, after receiving the instruction of the control module, the first servo motor rotates according to the actual environment, the angle is automatically adjusted, the precision of the rotation angle is 1 degree, and the rotation range is adjusted by the angle from 0 degree to 90 degrees clockwise and from 0 degree to 90 degrees anticlockwise. After receiving the instruction of the control module, the second servo motor rotates according to the actual environment, automatically adjusts the angle, and the precision of the rotation angle is 1 degree, and the rotation range is clockwise 0-180 degrees and anticlockwise 0-180 degrees.
In one embodiment, 18 infrared light emitting diodes comprise an infrared light emitting array; each kind of light is detected by at least 4 photodiodes, and any photodiode acquires a signal and outputs the signal to the control module.
In one embodiment, the power switch 10-1 is disposed on the power adapter board 10, and the control module is fixed, the control module includes a processing circuit and a control chip, the processing circuit includes a filter circuit and an amplitude adjustment circuit, and the control chip employs a PLC.
