Abstract
Description
Technical Field
[0001] This utility model relates to the field of communication technology, specifically a strobe light circuit for digital repeaters. In digital repeaters, the strobe light increases the visibility and warning effect of the digital repeater at night or in environments with poor visibility. Background Technology
[0002] Currently, traditional digital repeaters are mainly used for forwarding voice signals in the field. They can enable multiple devices to network automatically as needed, thereby extending the communication distance. To ensure communication effectiveness, repeaters are usually assumed to be located at a high position. However, their visibility is poor at night or in environments with low visibility, making it difficult to detect and identify the equipment in a timely manner when it is being retrieved after completing the task, thus affecting operational efficiency. Summary of the Invention
[0003] To address the shortcomings of existing digital repeaters in terms of poor visibility in low-visibility environments, this invention provides a strobe light circuit for digital repeaters. By connecting the strobe light circuit to the battery of the digital repeater, the strobe light can be added to improve the visibility and warning effect of the repeater at night or in low-visibility conditions, thus facilitating equipment retrieval and warning.
[0004] To achieve the above objectives, this utility model adopts the following technical solution: a strobe light circuit for a digital repeater, characterized in that the strobe light circuit comprises a power interface, a power switch, a power voltage regulator circuit, a timer circuit, and an LED light; the power interface is connected sequentially through the power switch, the power voltage regulator circuit, the timer circuit, and the LED light; the power interface is used to connect the battery to the strobe light circuit; the power switch is used to control the power on and off of the strobe light circuit; the power voltage regulator circuit regulates the battery voltage from +14.4V to +5V to provide a constant operating voltage for the timer circuit; the timer circuit is used to control the flashing frequency of the LED and provide the LED power supply voltage and drive current; the LED light is used for the overall flashing of the device.
[0005] The beneficial effects of this utility model are:
[0006] 1) The advantages of this circuit are: It drives LEDs using a timer circuit, generating stable and accurate timing signals, greatly simplifying the design, saving components, and reducing circuit complexity. The timer circuit has high reliability and stability, and can operate normally under harsh environmental conditions; the timer circuit is simple and easy to understand, making it easier to locate and solve problems.
[0007] 2) The strobe light circuit is applied to the digital repeater to enhance the device's visibility. As a communication device, the digital repeater is not conspicuous and is easily overlooked. However, adding strobe lights can greatly improve the device's visibility, enabling relevant personnel to quickly locate and identify the digital repeater in emergency situations, especially at night when there is insufficient light, thus allowing for timely and effective operations.
[0008] 3) Enhance emergency response capabilities. Digital repeaters are typically used in emergency communication scenarios, such as natural disasters and accident rescue. In these scenarios, rapid and accurate communication is crucial. Adding flashing lights makes digital repeaters more visible in emergency situations, allowing rescue personnel to quickly locate and use them, thereby improving emergency response capabilities.
[0009] 4) The equipment is highly expandable. As needed, the LEDs can be replaced with other colored bulbs, such as red or green, to adapt to different application scenarios. The circuit configuration can be changed to a continuous lighting mode to achieve lighting effects and enhance the convenience of nighttime operations. Attached Figure Description

[0011] Figure 2 This is the circuit diagram of the strobe light circuit of this utility model;
[0012] Figure 3 This is a circuit connection block diagram of an embodiment of the present utility model. Detailed Implementation
[0013] like Figure 1 As shown, the strobe light circuit consists of a power interface, a power switch, a power regulator circuit, a timer circuit, and an LED light.
[0014] like Figure 2 As shown, the specific connection of the strobe light circuit is as follows: pin 1 of the power chip N1 is grounded, pins 2 and 4 are connected together, and connected to one end of capacitor C4, capacitor C5, and resistor R1 respectively, and pins 4 and 8 of the time chip N2. The other ends of capacitors C4 and C5 are grounded. Pin 3 of the power chip N1 is connected to one end of capacitors C1 and C3 and one end of power switch S1. The other end of power switch S1 is connected to pin 1 of battery interface XS1. The other ends of capacitors C1 and C3 and pin 2 of battery interface XS1 are grounded respectively. The other end of resistor R1 is connected to one end of resistor R2 and pin 7 of time chip N2. The other end of resistor R2 is connected to one end of capacitor C6 and pins 6 and 2 of time chip N2. The other end of capacitor C6 is grounded. Pin 3 of time chip N2 is connected to the positive terminal of the LED through resistor R3. The negative terminal of the LED is grounded. Pin 1 of the power chip N1 is grounded.
[0015] The power supply chip N1 is model number TLV761; the timer chip N2 is model number NS555.
[0016] Example 1, such as Figure 3 As shown, the strobe light circuit is installed inside the digital repeater housing and connected to the digital repeater's battery via the battery interface XS1. The power switch S1 and the LED light are installed on the outer panel of the digital repeater housing.
[0017] When in use, turn on the power switch. Power is supplied to the timer chip N2 through the power supply regulator circuit. At the start of operation, timer chip N2 is in its initial state, with output pin 3 at a low level and the internal RS flip-flop in a reset state. When the power supply voltage is applied to timer chip N2, the internal capacitor begins to charge. The charging current flows through pin 6 of timer chip N2 to charge capacitor C6, causing the voltage of capacitor C6 to gradually rise. When the voltage of capacitor C6 reaches the threshold of the comparator inside timer chip N2, the comparator will output a high level, which will cause… When the internal RS flip-flop is set, pin 3 of the output circuit goes high. Once the internal RS flip-flop of the timer chip N2 is set, the high-level signal at pin 3 will cause the internal capacitor to discharge, causing the voltage at pin 6 of the timer chip N2 to drop. When the voltage of capacitor C6 drops below the comparator threshold at pin 2 of the timer chip N2, the internal comparator of the timer chip N2 will output a low level, which will reset the internal RS flip-flop and return pin 3 to a low level. This achieves the high-low switching of the output level, thereby driving the LED to blink.
