[0018] To make the technical problems, technical solutions and advantages of this utility model clearer, a detailed description will be given below in conjunction with the accompanying drawings and specific embodiments.

[0019] The mobile alarm provided by the present invention will be described in detail below with reference to the accompanying drawings, through specific embodiments and application scenarios.

[0020] like Figure 1 and Figure 2 As shown, the mobile alarm provided in this embodiment of the utility model includes a housing 101, an alarm system installed inside the housing (the alarm system is not shown as it is inside the housing), a telescopic rod 102, and a solar panel 103.

[0021] like Figure 2The diagram shows the rear structure of the portable alarm. A retractable rod 102 is located on the back of the housing 101. When the portable alarm needs to be moved, the retractable rod 102 is pulled up; when the portable alarm does not need to be moved, the retractable rod 102 is retracted. The size and material of the retractable rod can be flexibly set by those skilled in the art based on factors such as the size of the housing and the weight of the portable alarm. No specific limitations are imposed in this embodiment.

[0022] Multiple alarm indicator lights 1011 are provided in the first area on the front of the enclosure 101 near the top of the enclosure; multiple holes 1012 are provided in the second area on the front of the enclosure 101 away from the top of the enclosure.

[0023] A solar panel 103 is installed on the outside of the enclosure 101 and connected to the alarm system to power the alarm system. Multiple alarm indicator lights 1011 are connected to the alarm system and are used to output the alarm light signal emitted by the alarm system. The hole 1012 is used to output the alarm sound signal emitted by the alarm system. In actual implementation, it can be set to emit only an alarm sound signal or an alarm light signal after receiving an alarm signal, or it can be set to emit both alarm sound signals and alarm light signals simultaneously to achieve a better warning effect.

[0024] In this embodiment, as Figure 1 As shown, the mobile alarm may also include N pulleys 104; the base of the mobile alarm housing 101 is provided with N bases 105, and each base 105 is provided with a pulley 104, wherein N is greater than or equal to 2.

[0025] When the mobile alarm needs to be moved, the retractable rod is pulled up, and the alarm is dragged. Because the mobile alarm housing has casters at the bottom, dragging is easier. The specific number of casters can be flexibly set by those skilled in the art based on the length of the mobile alarm base; this embodiment does not impose a specific limitation. For example, N can be set to 2, 4, or 6, and of course, it can also be set to an odd number.

[0026] In this embodiment, there are two solar panels; one solar panel can be folded onto each of the two sides of the housing; the solar panels are unfolded to power the power supply module when the mobile alarm is working; the solar panels are closed when the mobile alarm is not working, making it convenient to move the mobile alarm.

[0027] In this embodiment, the two sides of the housing 101 are each provided with a recessed area of ​​the same size as the plane of the solar panel 103; the top of the solar panel is foldable and connected to the upper edge of the recessed area, and the solar panel is embedded in the recessed area when closed. This embedded structure can prevent the sides of the solar panel from being bumped, thereby extending the service life of the solar panel.

[0028] In this embodiment, the mobile alarm unit has a total of four alarm indicator lights on the front of its housing, arranged at equal intervals. Using four alarm indicator lights balances the effectiveness of the alert and the area occupied by the lights, thus freeing up more space on the front of the housing for other functional components. The specific number of alarm indicator lights can be flexibly determined by those skilled in the art based on the length of the mobile alarm unit's base; this embodiment does not impose a specific limitation. For example, it can be set to two or six, or even an odd number. The alarm indicator lights can also be arranged at unequal intervals, or even in multiple rows. The alarm indicator lights are red and blue flashing lights. Red and blue flashing lights are energy-efficient and emit more conspicuous alarm light.

[0029] In this embodiment, a push-button switch is provided on one side of the mobile alarm housing 101. The mobile alarm can be switched on and off by controlling this switch (the switch is connected in series between the power supply module and the alarm system to control the power supply of the alarm system). It can be located on the left or right side of the housing 101, and this embodiment of the present invention does not impose any specific restrictions on this.

[0030] In this embodiment, the back of the mobile alarm cabinet 101 is designed as an openable door structure, and a keyhole is provided on the back. The back of the cabinet can be opened by the keyhole, which makes it convenient for staff to operate the internal components of the cabinet, such as replacing internal components.

[0031] In this embodiment, as Figure 3 As shown, the alarm system includes a microprocessor and a wireless signal receiver electrically connected to the microprocessor, a power supply module, an alarm indicator light, and an alarm voice chip. The wireless signal receiver is wirelessly connected to the alarm signal triggering terminal. The input end of the power supply module is connected to a lithium battery, the input end of the lithium battery is connected to a charging management chip, the input end of the charging management chip is connected to a solar panel, and the output end of the alarm voice chip is connected to a speaker.

[0032] The microprocessor is a single-chip microcomputer. In this embodiment, a low-power MSP430 series single-chip microcomputer is used with a power supply voltage of 3.3V.

[0033] The alarm signal triggering terminal uses a wireless sensor or wireless gateway node. When the wireless sensor detects abnormal environmental parameters, it wirelessly sends an alarm signal to the wireless signal receiver. The wireless signal receiver can be a Bluetooth module, a WiFi module, or a 4G / 5G module; these wireless communication modules are common in existing technology and their models are not limited. The wireless signal receiver is a wireless signal receiving chip that uses the same communication method as the wireless sensor or wireless gateway node.

[0034] The alarm voice chip, model WT6040-8S, can be communicated / controlled via buttons, pulse counting, one-wire serial port, and two-wire serial port. It features 16 levels of volume control and 80 seconds of voice storage on a single chip. It also integrates an 8R0.5W power amplifier circuit, capable of directly driving a speaker (PWM output) to emit an alarm sound. The alarm signal emitted by the speaker is output to the outside of the mobile alarm enclosure through a hole located in the second area on the front of the enclosure.

[0035] In this embodiment, the lithium battery is housed inside the casing. The solar panel charges the lithium battery via a charging management chip, and the lithium battery converts its voltage into the operating voltage for the microprocessor and other modules via a power supply module.

[0036] The charging management chip uses the CN3791 solar charging management chip, which features maximum power point tracking, supports a wide input voltage range of 4.5V to 28V, can perform complete charging management for a single lithium battery, has a maximum charging current of 4A, and has multiple protection functions, making it suitable for various ambient temperatures. By using solar panels to store electricity for the lithium battery during daytime operation, it also contributes to energy conservation and environmental protection.

[0037] The power supply module is a DC voltage regulator chip that converts the relatively high voltage output from the lithium battery into the operating voltage of modules such as the microprocessor. In this embodiment, the power supply module uses the L1117 series voltage regulator chip. The LM1117 has an adjustable voltage version, which can achieve an output voltage range of 1.25V to 13.8V through two external resistors. There are also five models with fixed voltage outputs (1.8V, 2.5V, 2.85V, 3.3V, and 5V). Figure 4 The image shows the L1117-3.3 voltage regulator circuit, which can convert the lithium battery voltage to 3.3V DC voltage to power the microprocessor. Other modules can use appropriate voltage regulator chips as needed.

[0038] Alarm indicator circuit such as Figure 5 As shown, in the alarm state, terminals M0-M3 are at a low level, and the indicator light between voltage VCC and the low level forms a conductive path, causing the indicator light to illuminate.

[0039] In summary, the mobile alarm described in this utility model achieves continuous power supply through a combination of solar energy and lithium batteries. The core structure consists of two foldable solar panels on both sides of the housing. When the alarm is in operation, the solar panels are unfolded from the grooves on the side of the housing (the top of the solar panel folds and connects to the upper edge of the groove, allowing it to be fully embedded in the groove when closed, preventing damage from impacts). The solar panels absorb light energy and convert it into electrical energy, which is then used to charge the lithium battery inside the housing via a CN3791 solar charging management chip. The electrical energy stored in the lithium battery is processed by a power supply module to power the entire alarm system. The power supply module uses an L1117 series voltage regulator chip, which converts the voltage output from the lithium battery into an appropriate operating voltage for each component, such as providing a 3.3V DC voltage for the microprocessor using the MSP430 series, ensuring stable operation of all components in the alarm system. When the alarm is not in operation, the solar panels are folded and embedded in the grooves, without affecting the movement of the device.

[0040] In the signal triggering stage, the alarm signal triggering terminal is a wireless sensor or wireless gateway node. When the terminal detects abnormal parameters in the industrial environment (such as excessive concentration of hazardous gases, equipment malfunction signals, etc.), it will send an alarm signal via wireless communication (Bluetooth, WiFi, or 4G / 5G). The wireless signal receiver inside the enclosure must use the same communication method as the triggering terminal to ensure stable signal reception. After receiving the abnormal signal, the receiver immediately transmits the signal to the MSP430 series microprocessor. On one hand, the microprocessor sends signals to the four equally spaced alarm indicator lights in the first area on the front of the enclosure (near the top of the enclosure). These indicator lights are red and blue flashing lights, which are energy-saving and highly visible. Upon receiving the command, they flash immediately, outputting an alarm light signal for easy long-distance identification. On the other hand, the microprocessor activates the alarm voice chip, directly driving the speaker to generate an alarm sound signal. The sound is transmitted through multiple holes in the second area on the front of the enclosure (away from the top of the enclosure), ensuring that the sound propagation is not obstructed by the enclosure, achieving simultaneous sound and light alarm and covering the warning needs in different scenarios.

[0041] It should be noted that, in this document, the terms "comprising," "including," or any other variations thereof are intended to cover non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements includes not only those elements but also other elements not expressly listed, or elements inherent to such a process, method, article, or apparatus. Unless otherwise specified, an element defined by the phrase "comprising one..." does not exclude the presence of other identical elements in the process, method, article, or apparatus that includes that element.

[0042] The above description is a preferred embodiment of the utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the principle of the utility model, and these improvements and modifications should also be considered within the scope of protection of the utility model.
