The utility model discloses in the processing apparatus embodiment based on distributed acquisition information, this processing apparatus based on distributed acquisition information's schematic structure diagram is shown in FIG. 1.

Especially, when adopting the loRa module, its communication distance is far away, and communication performance is comparatively stable, is applicable to the occasion that requires highly to communication quality.
Fig. 2 is a schematic circuit diagram of a power supply module in this embodiment, the power supply module 2 includes a first resistor R1, a second resistor R2, a first transistor Q1, a first diode D1, a first capacitor C1, a second capacitor C2, a three-terminal regulator U1, a second regulator D2, a third resistor R3, a voltage output terminal Vo, a third capacitor C3, a thyristor VS, a fourth capacitor C4, a fourth resistor R4, a rectifier bridge Z, a transformer T, and a voltage input terminal Vin, an emitter of the first transistor Q1 is connected to a cathode of the first diode D1 and one end of the first resistor R1, a base of the first transistor Q1 is connected to one end of the first capacitor C1 and an input terminal of the three-terminal regulator U1, a collector of the first transistor Q1 is connected to an anode of the first diode D1, an output terminal Vo of the three-terminal U1, one end of the second capacitor C2, one end of the second capacitor C2, and a cathode of the second regulator U2, the anode of the second voltage-regulator tube D2 is connected to one end of a fourth resistor R4, the control electrode of the thyristor VS and one end of a third resistor R3, the other end of the first resistor R1 is connected to the other end of the first capacitor C1, the negative connection terminal of the three-terminal regulator U1, the other end of the second capacitor C2, the other end of the third resistor R3, the other end of the voltage output Vo, one end of the second resistor R2, one end of the third capacitor C3, the cathode of the thyristor VS, one end of the fourth capacitor C4, one output end of the rectifier bridge Z and the other end of the fourth resistor R4, the other end of the second resistor R2 is connected to the other end of the third capacitor C3, the anode of the thyristor VS, the other end of the fourth capacitor C4 and the other output end of the rectifier bridge Z, one input end of the rectifier bridge Z is connected to one end of the secondary winding of the transformer T, the other end of the rectifier bridge Z is connected to the other end of the secondary winding, one end of the primary coil of the transformer T is connected with one end of the voltage input end Vin, and the other end of the primary coil of the transformer T is connected with the other end of the voltage input end Vin.

It should be noted that in this embodiment, the resistance of the fourth resistor R4 is 43k Ω, and certainly, in practical applications, the resistance of the fourth resistor R4 may be adjusted according to specific situations, that is, the resistance of the fourth resistor R4 may be increased or decreased according to specific situations.
After the 220V alternating current input by the voltage input end Vin is reduced by the transformer T, the alternating current is rectified and filtered by the rectifier bridge Z and subsequent circuits, so that the output end obtains stable 5V voltage. The maximum output current of the three-terminal regulator U1 is 1.5A, and if the output current is larger than 1.5A, the output current is enlarged, so that a high-power first triode Q1 is connected to the periphery of the three-terminal regulator U1. The adopted parallel connection type current spreading mode is that the input end of a three-terminal voltage regulator U1 is connected with the base electrode of a first triode Q1, the output end of a three-terminal voltage regulator U1 is connected with the collector electrode of a first triode Q1, and therefore the sum of the two output currents can meet the requirement of outputting 1.5A current.

The voltage protection circuit is composed of a second voltage regulator tube D2, a third resistor R3, a silicon controlled rectifier VS and the like.
When the power supply works normally, the output voltage is 5V, and the silicon controlled rectifier VS is in a cut-off state. When the output voltage of the voltage-stabilized power supply exceeds a limit value due to some reason (such as damage of an integrated block or breakdown of a regulating tube), namely greater than or equal to 5.5V, the second voltage-stabilized tube D2 breaks down, and the sampling voltage rises to trigger the silicon controlled rectifier VS to be conducted, so that the load is protected.
In order to prevent the reverse peak voltage from breaking down the three-terminal regulator U1 or the first transistor Q1, a first diode D1 is connected in parallel between the input terminal and the output terminal of the three-terminal regulator U1 and between the emitter and the collector of the first transistor Q1, and is mainly used for protecting the three-terminal regulator U1 and the first transistor Q1. The fourth capacitor C4 is an output capacitor of the rectifier bridge Z, and can suppress high frequency harmonic interference. The second resistor R2 provides a bleed current loop for the third capacitor C3.
In this embodiment, the first transistor Q1 is a PNP transistor. Of course, in practical applications, the first transistor Q1 may also be an NPN transistor, but the circuit structure may also be changed accordingly.

The fifth capacitor C5 is a coupling capacitor for preventing interference between the first transistor Q1 and the three-terminal regulator U1, so as to further enhance the safety and reliability of the circuit. It should be noted that in the present embodiment, the capacitance of the fifth capacitor C5 is 450pF, and certainly, in practical applications, the capacitance of the fifth capacitor C5 may be adjusted accordingly according to specific situations.
In this embodiment, the power supply module 2 further includes a third diode D3, an anode of the third diode D3 is connected to a cathode of the second voltage regulator D2, and a cathode of the third diode D3 is connected to one end of the voltage output terminal Vo. The third diode D3 is a current limiting diode for current limiting protection to further enhance the safety and reliability of the circuit. It should be noted that in the present embodiment, the third diode D3 has a model E-822, and in practical applications, other types of diodes having similar functions may also be used as the third diode D3.
In this embodiment, the power supply module 2 further includes a fifth resistor R5, one end of the fifth resistor R5 is connected to the collector of the first transistor Q1, and the other end of the fifth resistor R5 is connected to the output end of the three-terminal regulator U1. The fifth resistor R5 is a current limiting resistor for performing current limiting protection to further enhance the current limiting effect. It should be noted that in the present embodiment, the resistance of the fifth resistor R5 is 56k Ω, and certainly, in practical applications, the resistance of the fifth resistor R5 may be adjusted accordingly according to specific situations.
