[0046] Figure 1 FIG. 1 is a structural block diagram of a warning device with communication function according to an embodiment of the present invention. Figure 1 As shown, the warning device includes a light board 111, a first photoelectric circuit 112, a LoRa communication circuit 113 and a processing circuit 114. The first photoelectric circuit 112 is used to collect data collected by an external device, and to step down the data voltage of the data collected by the external device in a photoelectric coupling manner; the processing circuit 114 is respectively connected to the light board 111, the first photoelectric circuit 112 and the LoRa communication circuit 113, and is used to control the lighting of the light board 111 according to the data collected by the external device, and transmit the data collected by the external device to the terminal through the LoRa communication circuit 113.

[0047] Among them, the data collected by the external device may include the operating status of the external device and the working parameters during the operation process, etc., which can characterize the working conditions of the external device; the first photoelectric circuit 112 may include a phototransistor, and the phototransistor includes a light-emitting side and a light-receiving side. The light-emitting side receives the electrical signal of the external device collecting data, and then converts the electrical signal into an optical signal, and the light-receiving side converts the optical signal into an electrical signal. Since the data voltage of the input external device collecting data is relatively high, usually exceeding 10V, and the voltage of the data received by the processing circuit 114 is generally around 3.3V, the data voltage of the external device collecting data can be reduced through the first photoelectric circuit 112, thereby meeting the data processing requirements of the processing circuit 114. In addition, the first photoelectric circuit 112 can also play an isolation role to ensure the accuracy of the transmission of the data collected by the external device.

[0048] The light board 111 may include 90 programmable LED three-color lamp beads arranged in an array. The processing circuit 114 can control the light emission of these lamp beads by sending an LED control signal. In addition to the traditional red, yellow and green three-color lighting method, the entire light board 11 (red, yellow, green) can also achieve single-color (red, yellow, green) and light rotation lighting effects, with various lighting combinations.

[0049] The LoRa communication circuit 113 may include a flexible board antenna 1132 and a LoRa chip 1131. The processing circuit 114 may first convert the data collected by the external device into a serial digital signal, and then transmit it to the LoRa chip 1131. The LoRa chip 1131 then converts the data collected by the external device into a LoRa radio frequency signal, and finally transmits it outwardly through the flexible board antenna 1132. In addition to the sending function, the LoRa communication circuit 113 may also have a receiving function; in one embodiment, the data collected by the external device may also be received by the LoRa communication circuit 113, and then transmitted to the processing circuit 114, and the processing circuit 114 lights up the light board 111.

[0050] The LoRa communication circuit 113 can realize long-distance wireless communication. Under the same power consumption conditions, its transmission distance is farther than other wireless methods. Under the same power consumption conditions, the communication distance is 3-5 times higher than the traditional wireless radio frequency, achieving the unity of low power consumption and long distance. Compared with other wireless communication methods, such as 4G networking method, the LoRa wireless communication method adopted in this embodiment has lower material and usage costs.

[0051] After receiving the data collected by the external device after the voltage is stepped down by the first photoelectric circuit 112, the processing circuit 114 will light up the light board 111 according to the data collected by the external device to remind the staff on site, and on the other hand, the data collected by the external device will be sent to the terminal through the LoRa communication circuit 113 to achieve long-distance monitoring. In this way, the data collected by the external device is transmitted to the terminal by wireless communication, and there is no need for on-site staff to record, which reduces labor costs and improves monitoring efficiency. Among them, the terminal can be a host computer.

[0052] The above-mentioned warning device isolates and reduces the data voltage of the data collected by the external device through the first photoelectric circuit 112, and then the processing circuit 114 sends the data collected by the external device to the terminal through the LoRa communication circuit 113. At the same time, the lighting of the light board 111 is controlled according to the data collected by the external device, thereby realizing the unification of on-site alarm and long-distance monitoring. There is no need to rely on on-site staff to record alarms, the labor cost is low, and the monitoring efficiency is high.

[0053] In one embodiment, Figure 2As shown, the warning device also includes a second photoelectric circuit 115, which is used to receive a color light input signal from an external device and to reduce the voltage of the color light input signal by photoelectric coupling; the processing circuit 114 is also connected to the second photoelectric circuit 115, and is used to control the lighting of the light board 111 according to the reduced voltage color light input signal.

[0054] It can be understood that the color light input signal carries the lighting information of the light board 111, so the processing circuit 114 can control the lighting of the light board 111 according to the color light input signal. The signal voltage of the external input color light input signal is usually greater than 15V. In order to ensure that the processing circuit 114 can receive and process normally, it is necessary to step down the voltage. Among them, the second photoelectric circuit 115 may include a phototransistor, and the light-emitting side of the phototransistor can receive the color light input signal of the external device, and then convert it into an optical signal, and then the light-receiving side of the phototransistor converts the optical signal into an electrical signal, so that the voltage of the color light input signal can be reduced by the second photoelectric circuit 115. In addition, the second photoelectric circuit 115 can also play an isolation role, ensuring the accuracy of the color light input signal transmission. In one embodiment, the processing module can also transmit the lighting information of the light board 111 in the color light input signal to the terminal through the LoRa communication circuit 113.

[0055] Specifically, the color lamp input signal can be input through the input line, wherein the input line includes 4 lines, namely 3 signal lines corresponding to the three colors of red, yellow and green, and 1 common terminal. The color lamp input signal is input through at least one signal line, and when the voltage difference (regardless of positive or negative) between the signal line and the common terminal reaches above the threshold, the lamp board 111 lights up the lamp of the corresponding color.

[0056] In this embodiment, the second photoelectric circuit 115 is used to reduce the voltage of the color light input signal, so that the processing circuit 114 can normally receive the color light input signal, and then control the lighting of the light board 111 according to the color light input signal, thereby realizing the traditional lighting function of the light board 111.

[0057] In one embodiment, Figure 3 As shown, the warning device further includes a power circuit 110, and the power circuit 110 is used to provide power supply energy to the warning device.

[0058] It can be understood that the power supply circuit 110 can be a power supply that requires external power supply, which can provide electrical energy to the electrical components in the entire warning device to ensure the normal operation of the warning device.

[0059] In one embodiment, Figure 4 As shown, the power circuit 110 may include a power chip 1101, and the power chip 1101 is used to receive an external input power source to obtain power supply energy.

[0060] It can be understood that the power chip 1101 can receive power from an external power source, reduce the voltage of the external power source to the working voltage of the warning device, and finally obtain power supply power, and then use the power supply power to power the internal components of the warning device. Among them, the working voltage of the warning device can be, for example, 5V, so the power chip 1101 can reduce the voltage of the external power source to 5V, and then power the warning device.

[0061] In one embodiment, Figure 5 As shown, the power supply circuit 110 also includes a rectifier circuit 1102, which is used to receive a color light input signal from an external device, and transmit the color light input signal to the power supply chip 1101 after rectifying the color light input signal; the power supply chip 1101 is also used to receive the color light input signal output by the rectifier circuit to obtain power supply energy.

[0062] The rectifier circuit 1102 can realize reverse connection protection for the power chip 1101. No matter what the polarity of the color light input signal input to the rectifier circuit 1102 is, the polarity of the output signal of the rectifier circuit 1102 is fixed, thus preventing damage to the power chip 1101. In one embodiment, the rectifier circuit 1102 may include a rectifier bridge circuit.

[0063] It can be understood that after the color light input signal is input, it is used for power supply through one branch and output to the second photoelectric circuit 115 through another branch, thereby realizing the lighting control of the light board 111. In this way, the internal power supply of the warning device can be provided in two ways, one is that the external input power supply is powered by the power chip 1101, and the other is that the power chip 1101 is powered by receiving the color light input signal; as long as any one of the ways exists, the power supply of the warning device can be realized.

[0064] In one embodiment, Figure 6 As shown, the warning device further includes a communication circuit 485 119 , which is connected to the processing circuit 114 and is used for transmitting data collected by the external device between the external device and the processing circuit 114 .

[0065] It can be understood that the 485 communication circuit 119 adopts the RS-485 serial bus standard, which may include a 485 transceiver. The received signal is converted into a serial signal by the 485 transceiver and then transmitted to the processing circuit 114. Similarly, the serial signal sent by the processing circuit 114 can also be converted into a 485 level by the 485 transceiver and sent to the external device. The 485 communication circuit 119 can realize the reception and transmission of data collected by the external device. In addition, the 485 communication circuit 119 can also realize wired networking, receive host computer commands, receive warning information, and report the current operating status of the external device.

[0066] The 485 communication circuit 119 can communicate efficiently over long distances in an environment with electronic noise. In a linear multi-point bus configuration, there can be multiple receivers on a network, so it is suitable for industrial environments.

[0067] This embodiment adopts 485 communication circuit 119 and LoRa communication circuit 113 to provide wired and wireless networking modes respectively. After networking, the working status of the on-site equipment can be uniformly monitored, recorded and managed through the host computer or server, which reduces labor costs and improves reliability.

[0068] In one embodiment, Figure 7 As shown, the warning device further includes a Bluetooth circuit 116 , which is connected to the processing circuit 114 and is used to transmit the configuration parameters of the warning device between an external transceiver device and the processing circuit 114 .

[0069] Among them, the configuration parameters of the warning device are the configuration parameters of some components in the warning device, for example, they may include the configuration parameters of the light board 111, the 485 communication circuit 119, the LoRa communication circuit and the processing circuit; the configuration parameters of the light board can be used to implement the functional configuration of the light board so that the light board emits light in a specific mode; the configuration parameters of the 485 communication circuit 119 can be used to configure the communication protocol of the communication circuit 115; the configuration parameters of the LoRa communication circuit can be used to configure the communication frequency of the LoRa communication circuit; the configuration parameters of the processing circuit 114 can be used to define the input of the digital IO port of the processing circuit 114 when the processing circuit 114 is connected to the first photoelectric circuit 112 and the second photoelectric circuit 115.

[0070] Among them, the Bluetooth circuit 116 may include a Bluetooth chip 1161 and an onboard antenna 1162. When the configuration parameters of the warning device are sent outwardly through the Bluetooth circuit 116, the Bluetooth chip 1161 can receive the configuration parameters of the warning device serially output by the processing circuit 114, and then send them outwardly through the onboard antenna 1162; when the Bluetooth circuit 116 receives the configuration parameters of the warning device sent externally, they are first received by the onboard antenna 1162, and then transmitted to the Bluetooth chip 1161, and then transmitted to the processing circuit 114. Finally, the processing circuit 114 performs functional configuration of the corresponding components in the warning device according to each parameter.

[0071] In this way, the user can use a mobile phone or a computer with a Bluetooth transceiver to customize the components of the warning device through the Bluetooth circuit 116, which is flexible, efficient, convenient and fast. In addition, the Bluetooth circuit 116 is used to configure the functions of the light board 111, without wiring or disassembling the light board 111, which is convenient and fast, and can efficiently realize short-distance data transmission.

[0072] In one embodiment, Figure 8As shown, the processing circuit 114 is also used to output a control signal; the warning device also includes a buzzer 117, which is connected to the processing circuit 114 and is used to send a sound alarm signal according to the control signal.

[0073] It can be understood that the warning device can be provided with a buzzer 117 for sound alarm in addition to using the light board 111 for light signal alarm, thereby improving the success rate of the alarm. Among them, the processing circuit 114 can output a control signal when there is abnormal data in the data collected by the external device received.

[0074] In one embodiment, Fig. 9 As shown, the warning device also includes a reset trigger circuit 118, which is connected to the processing circuit 114 and is used to output a reset signal when externally triggered; the processing circuit 114 is also used to control the warning device to return to an initial state according to the reset signal.

[0075] It can be understood that the reset trigger circuit 118 can restore the initial state of each component in the warning device, including but not limited to the communication protocol of the 485 communication circuit 119, the communication frequency of the LoRa communication circuit, the light board 111 light mode, the parameter configuration of the processing circuit 114, etc.

[0076] The reset trigger circuit 118 may include a button, and a driving signal may be generated by an external trigger button and transmitted to the processing circuit 114 , and then the processing circuit 114 controls each component to restore the factory settings.

[0077] In one embodiment, the first optoelectronic circuit 112 has two data receiving ports.

[0078] It can be understood that the first photoelectric circuit 112 has two data receiving ports, indicating that the first photoelectric circuit 112 can realize the reception of 2-bit data, thereby improving the data reception efficiency. Specifically, the first photoelectric circuit 112 may include two phototransistors, one end of the light-emitting side of each phototransistor receives data through an input line, and the other end is connected to a common end. When the voltage difference between any input line and the common end (the input line and the common end do not distinguish polarity) is in the range of (10V to 30V), the light-receiving side of the phototransistor will output a high level to the processing circuit 114, thereby realizing the step-down of the data voltage of two bits of data.

[0079] Fig.10 is a structural block diagram of a warning device according to another embodiment, such as Fig.10As shown, the warning device includes a light board 111, a first photoelectric circuit 112, a second photoelectric circuit 115, a LoRa communication circuit 113, a processing circuit 114, a power circuit 110, a 485 communication circuit 119, a Bluetooth circuit 116, a buzzer 117 and a reset trigger circuit 118; wherein the power circuit 110 includes a power chip 1101 and a rectifier circuit 1102. Through the combination of the above functional modules, the use requirements of most use scenarios can be met.
