[0053] The following describes embodiments of the present invention in conjunction with the accompanying drawings. It should be understood that the embodiments described herein are only used to illustrate and explain the present invention, and are not used to limit the present invention.
[0054] Figure 1 The structure of the wireless module 10 applied to the fire fighting device according to some embodiments of the present utility model is shown below. Figure 1 The wireless module 10 will be described.
[0055] like Figure 1 As shown, the fire fighting device in this embodiment includes a communication antenna 21 and at least one functional component 22. The communication antenna 21 can transmit and / or receive wireless signals so that the fire fighting device can communicate with the control center or other fire fighting devices. Figure 1 A functional component 22 is shown in the figure. In different embodiments of the present invention, the fire fighting device may further include multiple functional components. The functional component 22 may specifically be a component that realizes a specific function of the fire fighting device, such as a sensor for detecting the environment, such as a temperature sensor, a smoke sensor, etc., and a component that sends an alarm signal, such as a light emitter, a buzzer, etc.
[0056] The wireless module 10 includes a first circuit board 11, a first control module 12, a radio frequency front-end module 13 and a driving circuit 14. In this embodiment, the first control module 12, the radio frequency front-end module 13 and the driving circuit 14 are integrated on the first circuit board 11 and packaged. The wireless module 10 can be installed in the fire fighting device as an independent communication control chip, which greatly improves the integration. The wireless module 10 can be produced and stored separately, which is conducive to simplifying the production process of the fire fighting device and reducing the production cost.
[0057] In this embodiment, the first control module 12 is configured to execute preset commands and control at least some functional components 22 in the fire-fighting device through preset commands. For example, the first control module 12 can control at least some functional components 22 to start or stop, or control at least some functional components 22 to increase output power or reduce output power, etc.
[0058] The RF front-end module 13 is signal-connected to the first control module 12 and the communication antenna 21 of the fire-fighting device, and the RF front-end module 13 is configured to control the communication antenna 21 to transmit and / or receive wireless signals. Specifically, for example, the RF front-end module 13 controls the communication antenna 21 to start or shut down, or the RF front-end module 13 can control the wireless signals transmitted and received by the communication antenna 21.
[0059] The drive circuit 14 is connected to the first control module 12 by signal, and the drive circuit can be controlled by the first control module 12 to output a preset voltage value and an excitation signal to drive at least part of the functional components 22. In the fire fighting device, different functional components 22, or the same functional components 22 in different operating states, have different power supply requirements. Usually, the functional component 22 used to send an alarm signal, such as a buzzer, needs to provide a boost circuit to meet the start-up requirements of the buzzer. When the first control module 12 in this embodiment controls multiple functional components 22, multiple drive circuits 14 can be encapsulated in the wireless module 10, corresponding to the multiple functional components 22 respectively, or it can be set to have one drive circuit 14 corresponding to multiple functional components 22 according to the actual application scenario.
[0060] In this embodiment, the driving circuit 14 not only provides a driving voltage (preset voltage value) for the functional component 22 , but also can output an excitation signal to the functional component 22 according to the first control module 12 .
[0061] In the existing fire fighting device, the communication chip is usually only used to control the fire fighting device to communicate with the outside, while the control of the functional component 22 in the fire fighting device and the driving circuit corresponding to the functional component are separately set, which leads to a high degree of complexity in the circuit design of the fire fighting device. In the embodiment of the utility model, the first control module 12 can not only cooperate with the RF front-end module 13 to transmit and / or receive wireless signals, but also control the functional component 22 of the fire fighting device through the driving circuit 14. For example, the first control module 12 is constructed based on the OpenCPU technology, and the limited resources of the processor can be applied to control the functional component 22, which can save the external micro control unit, which is conducive to simplifying the circuit design of the fire fighting device and reducing the production cost.
[0062] Moreover, in the present embodiment, a driving circuit 14 is also encapsulated in the wireless module 10. The wireless module 10 can be installed on a circuit board of the fire-fighting device and connected to an external circuit (outside the wireless module 10) through pins. The driving circuit 14 can reduce the complexity of the external circuit, and the driving circuit 14 encapsulated in the wireless module 10 can improve the reliability of the fire-fighting device.

In this embodiment, the fire fighting device includes a plurality of functional components 22, some of which can be controlled by the first control module 12, and another part of the functional components 22 can be controlled by the second control module 23. Further, some of the functional components 22 can also be configured to be controlled by the second control module 23 and the first control module 12 at the same time, for example, providing a partial redundancy design for the fire fighting device to improve the reliability of the fire fighting device.
[0064] Preferably, the second control module 23 can be configured as an integrated circuit, which can provide simple control for the functional component 22, such as controlling the start or stop of the functional component 22, which is conducive to simplifying the circuit design of the fire-fighting device, eliminating the need to set up an additional microcontroller unit outside the wireless module 10, and reducing the cost of the fire-fighting device.

Specifically, the timing module 15 includes, for example, a high-speed crystal and a low-speed crystal, which can provide an accurate clock source for the timer, and in this embodiment, the timing module 15 can also provide a clock source for the second control module 23 outside the wireless module 10, which can simplify the circuit design, save a set of timing crystals, such as 32k crystals, reduce the production cost, improve the reliability of the fire fighting device, and save the space inside the fire fighting device.
[0066] In the existing conventional design, timing modules need to be provided inside and outside the MCU (micro control unit) in the fire fighting device to provide clock sources respectively. In this embodiment, the timing module 15 is encapsulated inside the wireless module 10 and the timing module 15 is multiplexed.

[0068] The processor 122 is connected to the RF transceiver 121 by signal, and the processor 122 is configured to execute a corresponding preset command according to the signal of the communication antenna 21.

The RF transceiver 121 is configured to parse the wireless signal and transmit it to the processor 122. The processor 122 can execute a corresponding preset command according to the wireless signal, such as driving one or more functional components 22 in the fire-fighting device to start or stop. On the other hand, the processor 122 can also be configured to control the communication antenna 21 to transmit the wireless signal through the RF transceiver 121 and the RF switch 131 after executing the preset command.
