Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative efforts belong to the protection scope of the present invention.

At present, phototactic wave band pest trapping equipment in the market usually adopts a high-voltage power supply to supply power, such as a 24V power supply. The main control panel therein is generally provided with a high-voltage working circuit powered by the above high voltage, for example, a driving circuit for driving an accessed pest trapping lamp or other electric equipment. Meanwhile, the main control board is often provided with a low-voltage operating circuit that can only be powered by low power, for example, a main control circuit for controlling the operation of the driving circuit or a communication circuit for implementing remote communication, etc. However, most of the signals transmitted between the devices in the low-voltage working circuit are weak electric signals, and the weak electric signals are easily interfered by a high-voltage power supply connected with the high-voltage working circuit, so that the low-voltage working circuit works with deviation, and the working reliability of the pest trapping equipment with the specific phototaxis waveband is further reduced.

Therefore, the utility model provides a specific phototaxis wave band pest traps equipment and main control board thereof examines fig. 1 the utility model relates to an embodiment, specific phototaxis wave band pest traps equipment main control board includes:

a circuit board 00 on which a low voltage operating circuit 31 and a high voltage operating circuit 11 are provided, the low voltage operating circuit 31 and the high voltage operating circuit 11 being electrically connected; the high voltage operation circuit 11 includes a drive circuit 111 and a connector 112 electrically connected thereto, and the low voltage operation circuit 31 includes a main control circuit 311;

the connector 112 is arranged at the edge of the circuit board 00 and is used for connecting the trapping lamp; the driving circuit 111 is electrically connected with the power supply terminal and the main control circuit 311 respectively; the main control circuit 311 is used for controlling the driving circuit 111 to output the power supply voltage of the power supply end to the trap lamp through the connector 112 so as to enable the trap lamp to work;

a weak current mounting area 30, an isolation area 20 and a strong current mounting area 10 are arranged on the circuit board 00, and the isolation area 20 is arranged between the weak current mounting area 30 and the strong current mounting area 10; the low-voltage working circuit 31 is arranged in the weak current installation area 30, and the high-voltage working circuit 11 is arranged in the strong current installation area 10;

wherein, an isolation trench 21 is disposed in the isolation region 20.

In this embodiment, the circuit board 00 may be implemented by a glass fiber board, and the glass fiber board is used as the circuit board 00 of the main control board of the pest trapping device in the specific phototaxis band, so that the circuit board 00 can maintain a complete mechanical structure when the SMT patches pass through the furnace, and the flame retardancy and the heat dissipation of the main control board of the pest trapping device in the specific phototaxis band can be effectively improved. In addition, the purchase cost of the glass fiber board is low, so that the production cost of the main control board of the pest trapping device with the specific phototaxis wave band is effectively reduced.

In this embodiment, optionally, the driving circuit 111 may be formed by a constant current LED switch driving chip and its peripheral circuits, such as a resistor, a capacitor, an inductor, a switching device, a diode, and the like, so that under the control of the main control circuit 311, the power supply voltage (i.e., the power supply voltage output by the high-voltage power supply) connected to the power supply terminal, for example, the 24V voltage, is subjected to voltage boosting/voltage reducing conversion, and then the driving voltage is output to the trapping lamp through the connector 112 to light the trapping lamp. Optionally, the driving circuit 111 may also be implemented by directly using a switching device, such as a relay, an MOS transistor, an IGBT, etc., where an input terminal of the switching device is connected to the power supply terminal, an output terminal of the switching device is connected to the connector 112, and a controlled terminal of the switching device is connected to the main control circuit 311, so that the main control circuit 311 conducts an electrical connection path between the input terminal and the output terminal of the switching device under control thereof, so that a power supply voltage output connected to the power supply terminal is output to the trap lamp through the connector 112, and the trap lamp is turned on. It is understood that the number of the driving circuits 111 and the number of the connectors 112 may be plural, and the power supply terminal may also be implemented by using the connectors 112.

In this embodiment, the main control circuit 311 may be implemented by a main controller and its peripheral circuits, such as an MCU, a DSP (Digital Signal processing chip), and an FPGA (Field Programmable Gate Array), and its peripheral circuits may be implemented by a capacitor, a resistor, a crystal oscillator, and so on. It is understood that the connector 112 electrically connected to the main control circuit 311 may also be disposed in the low voltage operating circuit 31, so as to access an external trigger device, such as a key, etc., so that when a user triggers the external trigger device, the trigger device can output a corresponding trigger signal to the main control circuit 311 through the connector 112, so that the main control circuit 311 controls the driving circuit 111 to output a power voltage of a power source end to the trap lamp through the connector 112 to operate the trap lamp.

In addition, the low voltage operating circuit 31 may also be provided with a plurality of connectors 112 electrically connected to the main control circuit 311, so as to facilitate accessing to other external devices, and establish electrical connection with the main control circuit 311, so as to implement data interaction therebetween, for example, accessing to an external sensor, an external communication module, and the like.

In this embodiment, the connector 112 may be implemented by using a snap connector 112, so as to ensure that when an external device is connected, an electrical connection path between the external device and a corresponding circuit can be stably maintained, thereby reducing the risk that the external device is loosened and dropped, and improving the reliability of the pest trapping device for a specific phototaxis band.

In the present embodiment, as can be seen from the above, most of the signals transmitted between the devices in the main control circuit 311 in the low-voltage operating circuit 31 are weak low-voltage signals, and the power supply voltages supplied by the power supply to the driving circuit 111 in the high-voltage operating circuit 11 are high-voltage signals. Therefore, by providing the low-voltage operating circuit 31 in the weak current mounting area 30, providing the high-voltage operating circuit 11 in the strong current mounting area 10, and dividing the high-voltage operating circuit by the isolation area 20 having the isolation groove 21 therebetween to achieve physical isolation, it is possible to effectively reduce electromagnetic interference of a high-voltage signal in the high-voltage operating circuit 11 with respect to a weak current signal transmitted through the low-voltage operating circuit 31 during transmission, and in particular, interference with a high-frequency weak current signal transmitted through the low-voltage operating circuit 31. Meanwhile, as can be seen from the above embodiments, the driving circuit 111 in the high-voltage operating circuit 11 may be formed by a constant-current LED switch driving chip and its peripheral circuits, and the above-mentioned heat generating devices, such as a switch chip and a power device, may generate a large amount of heat during the operation process. Therefore, the grooves formed in the isolation region 20 can also effectively increase the heat dissipation speed of the circuit board 00 to reduce the heat accumulation around the heating device, thereby improving the working stability of the high-voltage working circuit and further improving the working reliability of the pest trapping device with the specific phototaxis wave band. Optionally, the number of the isolation grooves 21 may be one, that is, the circuit board in the isolation region is hollowed out, so as to realize physical isolation; optionally, in another embodiment, the number of the isolation grooves 21 may be multiple, and a certain gap (the circuit board may not be hollowed out at the gap) is provided between the multiple isolation grooves 21, so that the physical isolation is realized, the structural strength of the circuit board can be ensured, and the risk of damage to the circuit board during production, mounting, post-soldering, testing, warehousing, assembly, transportation and maintenance is reduced.

It should be understood that the utility model discloses specific phototaxis wave band pest trapping equipment mainly sets up in granary, grain stack, and often humidity ratio is bigger in the granary, forms steam easily, and the circuit board if be in under the environment of higher humidity for a long time, device and/or copper covering on it are easy to be corroded and then lead to whole equipment work to produce the trouble.

For this reason, in the present embodiment, the circuit board may be subjected to moisture-proof treatment. Optionally, in an embodiment, the circuit board may be coated with a three-proofing paint, so as to play a role in water vapor protection; optionally, in another embodiment, the circuit board may be encapsulated with epoxy resin, so that the epoxy resin on the circuit board after cooling may also perform the functions of accelerating heat dissipation, preventing salt fog, preventing mold, resisting earthquake, etc. while performing the function of preventing water vapor. Optionally, in another embodiment, a layer of nano plating layer may be further wrapped on the circuit board, and the wrapped nano plating layer does not change the overall structural size and shape of the current main control board while playing a waterproof and moistureproof effect, so that a manufacturer can conveniently install the main control board of the pest trapping device in a specific phototaxis waveband in the pest trapping device in the specific phototaxis waveband, thereby improving the production efficiency.

The utility model discloses specific phototaxis wave band pest trapping equipment main control board includes circuit board 00, is provided with low voltage operating circuit 31 and the high voltage operating circuit 11 of electricity connection each other on the circuit board 00 to and weak current installing zone 30, isolation zone 20 and forceful electric power installing zone 10. The high-voltage working circuit 11 includes a driving circuit 111 and a connector 112 electrically connected to the driving circuit 111, the low-voltage working circuit 31 includes a main control circuit 311, the connector 112 is disposed at an edge of the circuit board 00 and is used for connecting the trap lamp, the main control circuit 311 is used for controlling the driving circuit 111 to output a power voltage of a power source terminal to the trap lamp through the connector 112 so as to enable the trap lamp to work, the isolation region 20 is disposed between the weak current installation region 30 and the strong current installation region 10, the low-voltage working circuit 31 is disposed in the weak current installation region 30, and the high-voltage working circuit 11 is disposed in the strong current installation region 10. Meanwhile, a plurality of isolation trenches 21 are provided in the isolation region 20. Therefore, in the actual working process of the main control panel, the high-voltage signal of the power supply connected to the high-voltage working circuit 11 does not affect the weak-current signal output by the low-voltage working circuit 31, and the electromagnetic interference between the low-voltage working circuit 31 and the high-voltage working circuit is reduced, so that the working reliability of the pest trapping device in the specific phototaxis wave band is further improved.

In an embodiment of the present invention, referring to fig. 2 and 5, the circuit board 00 includes a top wiring layer 01 and a bottom wiring layer 02, and the weak current installation area 30, the isolation area 20 and the strong current installation area 10 are all disposed on the top wiring layer 01.

In the present embodiment, the weak current mounting region 30, the isolation region 20, and the strong current mounting region 10 are all provided on the upper wiring layer 01, and it is understood that the devices of the circuits in the above-described respective regions are also provided on the upper wiring layer 01. Thus, in the actual working process, the heat generated by different devices in different circuits on the top wiring layer 01 in the working process can be quickly conducted to the air, or conducted on the structure of the fixed circuit board 00 through the circuit board 00, and the situation of heat accumulation caused by too many devices on the other side (the bottom wiring layer 02) of the circuit board 00 cannot occur, so that the overall heat dissipation performance of the circuit board 00 is effectively improved.

Meanwhile, during the operation of the above circuits, high frequency signals may be generated, for example, high frequency switching signals output by the main control circuit 311 to the constant current LED switch driving chip. However, because there is no device on the other side (bottom wiring layer 02) of the circuit board 00, there is no influence on the high frequency signal generated by the circuit on the top wiring layer 01 (if there is a device on the other side of the circuit board 00, in the working process of all circuits on the circuit board 00, the signals generated by the devices on the two sides will interfere with each other, especially generate a large interference on the high frequency signal), so that the working stability and reliability of the low voltage working circuit 31 and the high voltage working circuit 11 on the circuit board 00 are ensured, and further the working reliability of the pest trapping device for a specific phototactic wave band is improved.

In addition, in another embodiment, referring to fig. 2 and 5, a ground copper clad layer is disposed on the bottom wiring layer, a ground copper clad layer is disposed on the blank region of the top wiring layer, and a via array 010 is further disposed on the blank region of the top wiring layer.

In this embodiment, the via array 010 is an array formed by combining a plurality of vias, and the vias are through holes capable of connecting a top layer wiring layer and a bottom layer wiring layer of the circuit board 00. After the wiring of the circuit on the circuit board 00 is finished, a vacant blank area without wiring or coated with copper still exists, and at the moment, grounding copper is arranged in the blank area of the top wiring layer and the blank area on the bottom wiring layer, so that the ground wire impedance is reduced, the loss of input current and output current on the circuit board 00 is reduced, and meanwhile, due to the fact that the area of the copper foil is increased, heat generated when the circuit works can be better conducted to the air, and the heat is prevented from being accumulated on the circuit board 00. In addition, since the isolation region 20 is also disposed on the top wiring layer, and there is a blank region without traces or copper in the isolation region 20, there is also a grounded copper in the blank region of the isolation region 20. Therefore, the electromagnetic interference of the high-voltage signal generated by the high-voltage circuit to the weak-current signal generated by the low-voltage circuit 31 during operation can be further reduced, and the reliability of the operation of the pest trapping device with the specific phototaxis wave band is further improved.

the antenna access seat 313 is used for accessing an external antenna; the communication circuit 312 is also electrically connected to the main control circuit 311, and the communication circuit 312 is closely attached to the antenna socket 313 in the weak current installation area 30.

In this embodiment, the communication circuit 312 may be implemented by using a communication chip and corresponding peripheral circuits thereof, for example, a WIFI communication chip, a 4G/5G communication chip, a bluetooth communication chip, an NB-IoT wireless communication chip, and the like. The communication circuit 312 may be connected to an external device through an external antenna, such as a mobile phone, a computer, a PLC, etc., so that a user can remotely communicate with the main control circuit 311 on the circuit board 00 through the external device to realize remote control.

It will be appreciated that the antenna socket 313 should be closely located to the communication circuitry 312 so as to reduce the distance of the electrical connection path between the communication circuitry 312 and the antenna socket 313, and at the same time the width of the electrical connection line between the antenna socket 313 and the communication circuitry 312 should be at least greater than 0.3mm. Therefore, when the antenna is connected and the communication circuit 312 begins to communicate with the external device to transmit signals, the loss of the signals connected/output through the antenna can be reduced as much as possible, the accuracy and stability of the communication data between the communication circuit 312 and the external device are improved, and the working reliability of the pest trapping device with the specific phototaxis wave band is further improved.

For example, the constant current LED switch driving chip and the inductor in its peripheral circuit should be tightly attached to each other as much as possible, so as to ensure the stability of signal transmission. It is understood that a certain distance should be kept between multiple driving circuits 111, or isolation is implemented by grounding copper so as to prevent signal interference between different driving circuits 111. Similarly, the plurality of main control circuit 311 devices in the main control circuit 311 need to be disposed closely for the same reason.

For example, a fan switch driving circuit 111 is provided in the strong electric installation area 10 for driving the fan under the control of the main control circuit 311, or a resistor divider circuit is provided in the weak electric installation area 30 for forming an NTC temperature detection circuit with an attached thermistor probe to detect the external temperature and transmit the detection result to the main control circuit 311. In addition, the functional circuit can also be an electronic scale circuit, a power consumption detection circuit of the trap lamp, a humidity detection circuit and the like. The functional circuits respectively comprise a plurality of functional circuit devices, and based on the same reason of the embodiment, the functional circuit devices in each functional circuit are arranged in a manner of being attached to each other, so that the stability and the efficiency of signal transmission in the circuit are effectively improved.

Because the bottom of the chip is usually tightly attached to the surface of the circuit board 00, the heat accumulated at the bottom of the chip during operation is difficult to be quickly conducted to the air, which easily causes heat accumulation, and further causes influence on the normal operation of the chip.

For this reason, referring to fig. 4 and 5, in an embodiment of the present invention, the top wiring layer 01 of the circuit board 00 is provided with a via array 010 at a position corresponding to the low voltage operating circuit 31 and the high voltage operating circuit 11.
