[0029] Please see Figures 1 to 3 As shown, this embodiment provides a unique agricultural multi-source sound and light alarm system, which consists of a sound and light alarm module, an alarm display module, and a power supply module connected together.

[0030] The sound and light alarm module includes a main control unit, a pulse triggering unit, and multiple light modules. The main control unit is connected to the pulse triggering unit through a relay switch, and the pulse triggering unit is connected to multiple light modules through a multi-channel logic gate circuit. The main control unit is configured to receive alarm signals from a remote server and control multiple light modules to alternately turn on and off through the pulse triggering unit.

[0031] The main control unit is also connected to a sound module, which is configured to provide TTS voice alarm.

[0032] The alarm display module is connected to the main control unit and the logic gate circuit respectively. The alarm display module is configured to receive the alarm level signal sent by the main control unit and display the alarm level synchronously with the lighting module.

[0033] The power supply module is configured to convert the input voltage into a system voltage to provide a stable voltage to each module.

[0034] Specifically, in this embodiment, the alarm system mainly includes multiple alarm modes such as TTS voice alarm, light alarm, and alarm level display. The overall function is described as follows: When the main control unit (U2, using the YED-RN111 chip) receives alarm data, it plays TTS voice information through the sound module (i.e., speaker); when the relay switch is closed, the four light groups alternately turn on and off according to the set channels; the main control unit sends the alarm level signal to the microcontroller (U12) through the serial port, and controls the alarm level display and non-display synchronously with the light group on / off control signal.

[0035] like Figure 3 As shown, the power module in this embodiment converts the input voltage into the system voltage through the voltage regulator chip U11 (MP1584EN model chip in this embodiment), providing a stable voltage for the entire system. Capacitors C8 and C13 are used for filtering, fuse F1 is used for current limiting, resistors R13 and R19 provide enable signals to keep the chip operational, diode D1 is used for power output rectification, and inductor L1 is used to suppress sudden current changes.

[0036] The unique agricultural multi-source audible and visual alarm system described in this embodiment is applied to urban agricultural meteorological support services. It can meet the disaster early warning needs of different application scenarios, realize dynamic multi-source audible and visual alarms, significantly reduce the cost of agricultural meteorological disaster early warning, make the early warning response capability faster, significantly improve the efficiency of direct agricultural meteorological services, and effectively solve the problems of high cost of current agricultural meteorological early warning information release terminal equipment, difficulty in personalized early warning customization, and single early warning method.

[0037] In addition, in practical use, the system can be integrated with existing agricultural meteorological monitoring systems (such as the "Fengling" WeChat mini-program for microclimate monitoring stations) and combined with suitable temperatures during crop growth and development to achieve dynamic multi-source audio and visual early warnings of high and low temperature meteorological disasters by region, crop, and type of disaster. At the same time, during the occurrence and development of major disastrous weather events, managers can broadcast weather warnings and crop management information to users by region and group, enabling rapid response and efficient handling of high and low temperatures and other disasters, and minimizing agricultural production losses caused by agricultural meteorological disasters.

[0038] In some implementations, such as Figure 1 As shown, the pulse triggering unit includes a signal generation circuit (U3, which uses an NE555 timer in this embodiment) and a counting pulse circuit (U5, which uses a CD4017 counter in this embodiment) connected together. Both the signal generation circuit and the counting pulse circuit are connected to a relay switch, and the counting pulse circuit is also connected to a logic gate circuit.

[0039] The logic gate circuit includes a first OR gate (U6, in this embodiment, U6 uses a 74L832 chip) and a second OR gate (U8, in this embodiment, U8 uses an SN74LVC2G32 chip). The first OR gate is directly connected to the counting pulse circuit, and the first OR gate is also connected to the counting pulse circuit through the second OR gate. The output terminal of the first OR gate is connected to the lighting module (in this embodiment, four lighting modules are used as an example, including U1, U4, U7, and U9) through multiple first switching transistors (the switching transistors matched with the lighting module include Q1, Q2, Q3, and Q4).

[0040] The first switching transistor is an NMOS transistor. The gate of the NMOS transistor is connected to one of the output pins of the first OR gate. The source of the NMOS transistor is grounded, and the drain of the NMOS transistor is connected to the lighting module (taking Q1 as an example, the gate of Q1 is connected to the AO pin of U6 through resistor R1, and the drain of Q1 is connected to the lighting module U1).

[0041] Specifically, in this embodiment, the specific circuit logic relationship is analyzed as follows when performing TTS voice alarm and light alarm:

[0042] (1) TTS voice alarm: YED-RN111 receives alarm data (YED-RN111 receives alarm instructions and cancel alarm instructions from the server through the 4G module) and plays TTS voice information through the connected speaker.

[0043] (2) Light alarm: When the relay switch S1 is closed, the light alarm circuit starts to work. According to the control signal of the NE555 timer, the 10 output terminals of the CD4017 counter output high and low level signals in sequence to control the light alarm and alarm display. The signal is sent to the gate of the NMOS transistor through the multiplexer chip to control the lighting of the lamp group.

[0044] For example, when pin 2 of the CD4017 counter outputs a high level and other pins output a low level, pin 3 of the 74LS32 (OR gate) counter outputs a high level. On one hand, at this time, the gate input of NMOS transistor Q1 is high, so NMOS transistor Q1 conducts, and lamp group U1 is powered on and brightens, while the other three lamp groups (such as U4, U7, and U9) are not powered on. On the other hand, pin 6 of OR gate U10 also outputs a high level, transistor Q5 conducts, enabling the digital tube display, and the microcontroller U12 sets the number to be displayed based on the data received from the serial port.

[0045] When only one pin of the CD4017 counter outputs a high level, the corresponding NMOS transistor can be turned on by the 74LS32 to control the lamp group to brighten, and at the same time, the alarm digital tube display will be turned on. The entire correspondence is shown in the table below:

[0046] CD4017 output pins 74LS32 output pins NMOS transistor Lighting Alarm display enabled 2、3 3 Q1 U1 Q5 4、7、11 6 Q2 U4 Q5 1、10 10 Q3 U7 Q5 5、6、9 13 Q4 U9 Q5

[0047] In some implementations, such as Figure 2 As shown, the alarm display module includes a microcontroller (U12), a digital display tube (DS1) connected to the microcontroller, and a third OR gate (U10, in this embodiment, U10 uses an OR chip) connected to the digital display tube.

[0048] The microcontroller communicates with the main control unit via a serial port. Multiple current-limiting resistors (including R15 to R23) are also provided between the microcontroller's I / O pins (P.0~P1.7 pins) and the segment selection pins of the digital display tube (such as a, b, c, d, e, f, g, DP pins).

[0049] The input terminals (A, B, C, D pins) of the third OR gate are connected to the output terminals (AO, BO, CO, DO pins) of the first OR gate. A second switching transistor, Q5, is connected between the output terminal of the third OR gate and the digital tube. The base of the second switching transistor is connected to the output terminal OUT of the third OR gate through the third resistor R12. The emitter of the transistor is connected to the A pin of the digital tube.

[0050] Specifically, in this embodiment, when displaying the alarm level, the specific circuit logic relationship is analyzed as follows:

[0051] Alarm level numbers: The microcontroller U12 receives the alarm level signals (1-9) sent by the main controller U2 via the serial port, enabling the P1.0 port to output different levels to control the displayed alarm numbers.

[0052] Alarm level enable: The LIGHTL, LEGHTR, LEGHTT, and LEGHTB outputs from the lighting alarm module are enabled or disabled by a multi-channel OR gate to display the alarm level on the digital tube. That is, when one light group is lit, the digital tube displays the alarm level; otherwise, it does not display anything, thus achieving synchronous linkage between the lighting and the alarm level.

[0053] In addition, when an alarm shutdown command is sent, the YED-RN111 shuts down the alarm, stopping the horn voice alarm and opening relay switch S1. NE555 and CD4017 are not connected to power and have no enable signal, thus disabling the light alarm and alarm display.

[0054] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and not to limit it. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of this utility model, and they should all be covered within the scope of the claims and specification of this utility model.

[0055] The embodiments of this application are intended to cover all such substitutions, modifications, and variations that fall within the broad scope of the appended claims. Therefore, any omissions, modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the embodiments of this application should be included within the protection scope of this application.
