Description

Technical Field

[0001] This utility model relates to a location information sign based on infrared optical communication that can send alarm information with one click, belonging to the field of infrared optical communication technology. Background Technology

[0002] Positioning and emergency alarm systems are crucial in industrial safety, medical monitoring, and fire rescue. Positioning information signs based on infrared optical communication, capable of sending alarm information with a single click, are essentially an integration of "communication technology + positioning technology + scenario-based hardware." This is driven by the significant bottlenecks of traditional solutions. RFID and radio frequency are susceptible to electromagnetic interference, potentially causing accidents in sensitive areas such as substations and hospital ICUs; spectrum licensing restrictions also limit deployment flexibility. GPS fails indoors due to building obstructions causing a sharp drop in indoor positioning accuracy, failing to meet the needs of high-risk indoor environments. Cellular networks suffer from drawbacks; base stations may fail during disasters, and continuous cellular communication consumes high power, hindering the battery life of portable devices. Infrared optical communication's non-radio frequency, low power consumption, concealment, and anti-interference characteristics perfectly match the "reliability" requirements of emergency scenarios.

[0003] This information sign, together with optical communication base stations and optical communication switching centers, forms a wireless optical communication positioning information system. Each optical communication base station has a unique identifiable ID code. Personnel / equipment wear information signs containing identification information and a unique identification code. The information sign communicates with the optical communication base station via infrared light, transmitting the unique information sign code and identification information to the base station via infrared waves. When an alarm button is pressed, an alarm code is sent, which is then transmitted to the optical communication switching center via the basic interconnection network. The optical communication switching center deciphers the location information by recognizing the ID code of the optical communication base station and decodes the encoded information, personnel identification information, and alarm information of the positioning information sign. This allows the location of the sign bearer and the alarm information to be marked on an electronic map, realizing the entire process of "alarm-positioning-information transmission." Summary of the Invention

[0004] To overcome the shortcomings of the prior art, this utility model provides a location information sign based on infrared optical communication that can send alarm information with one click. It works in conjunction with a wireless optical communication base station to build a communication network using infrared optical wireless communication technology to transmit location and alarm information.

[0013] The power management unit includes a charging management circuit responsible for controlling the charging of the lithium battery. It has a charging LED indicator and a full charge LED indicator. During charging, the blue LED charging indicator is always on, and the red LED full charge indicator is off.

[0018] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments.

In addition, unless otherwise explicitly specified and limited, the terms "installed," "connected," and "linked" should be interpreted broadly. For example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium; it can be a connection within two components. For those skilled in the art, the specific meaning of the above terms in this utility model can be understood according to the specific circumstances.

[0020] like Figure 1 and Figure 2The location information sign shown is based on infrared optical communication and has one-button alarm information transmission. It includes an infrared emitting LED, a signal power amplification circuit, an alarm button detection circuit, a standby button detection circuit, a central processing unit, an information sign configuration interface, a battery, and a power management unit. The central processing unit is connected to the infrared emitting LED through the signal power amplification circuit, and converts the compiled digital signal into an analog infrared light signal that can be transmitted over long distances and carries digital information.

[0021] The processor is connected to the alarm button detection circuit to periodically monitor the button status. The central processing unit (CPU) is connected to the standby button detection circuit to periodically monitor the button status. The CPU is connected to the information board configuration interface, which in turn connects to an external host computer to configure the information board's identification information and unique identification code. The information board's charging interface is connected to the lithium battery via a charging management chip included in the power management unit, and also connects to an external charger. The lithium battery powers the various circuit modules of the information board through the power management unit.

[0022] The location information sign also includes an e-ink screen and a character library chip. The central processing unit (CPU) is connected to the e-ink screen and the character library chip to control the e-ink screen's display. The e-ink screen on the front of the sign can be configured to display information as needed. The character library chip contains a dot-matrix Chinese character library, which can be accessed by the CPU via an address. The sign's configuration interface connects to a host computer, allowing the CPU to set the content displayed on the e-ink screen.

[0023] The location information sign also includes a battery power detection circuit. The central processing unit (CPU) is connected to the battery via this circuit to periodically monitor the battery power. The CPU is also connected to the lithium battery via a lithium battery power detection circuit to periodically monitor the lithium battery power.

[0024] The battery is a lithium battery, specifically a 3.7V lithium battery module.

[0025] The infrared emitting LED modulates information onto infrared light for transmission, using a single 940nm wavelength LED to send data. The visible light band is 380nm-780nm. In a visible light environment, there is less near-infrared light in the background, which helps improve the signal-to-noise ratio of the communication system. Furthermore, this band is harmless to the human eye, allowing for safe operation. The central processing unit compiles the information to be transmitted into pulses of a specific format, which are then amplified by a signal power amplifier circuit to drive the infrared LED to turn on and off.

[0026] The alarm button detection circuit consists of a tactile switch and a pull-down resistor.

[0027] The power management unit includes a charging management circuit responsible for controlling the charging of the lithium battery. It has a charging LED indicator and a full charge LED indicator. During charging, the blue LED charging indicator is always on, and the red LED full charge indicator is off. When the charging reaches the voltage threshold, the e-ink screen automatically refreshes the normal display content. When fully charged, the blue LED charging indicator is off, and the red LED full charge indicator is always on.

[0028] The alarm button detection circuit consists of a tactile switch and a pull-down resistor connected to the central processing unit (CPU). The CPU monitors the button status; if the alarm button is pressed continuously for more than 3 seconds, an alarm is triggered, the e-ink screen displays the alarm character, and the infrared optical communication link is immediately activated to send the location and alarm information. The standby button detection circuit also consists of a tactile switch and a pull-down resistor connected to the CPU. When the information board is not in use, a long press of the button enters standby mode to save power. To use it again, a short press of the button activates normal operation.

[0029] The lithium battery power is detected by measuring the battery voltage through the microcontroller's built-in ADC interface. Since measuring too high a voltage can damage the microcontroller chip, a resistor divider method is used for measurement. When the voltage drops below a set value, the e-ink screen displays "Please Charge," indicating that the battery is low and needs charging. A 5V / 1A power adapter is selected as the information sign charger and connected to the information sign via the charging interface.

[0030] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
