Description

Technical Field

[0001] The utility model relates to the field of fire fighting devices, in particular to a spark probe with a carrier communication function. Background Art

[0002] In industrial production environments, the application of spark detectors is crucial for fire warning systems. They are responsible for monitoring fire sources in the environment. Once a spark is detected, the alarm system will be triggered to prevent the occurrence of fire in time. In general, spark detectors may communicate with the monitoring system through wired or wireless means.

[0003] Wired communication: The spark probe can be directly connected to the monitoring system through wired media such as cables or optical fibers to achieve real-time data transmission and remote control. This method is stable and reliable, but the wiring is relatively complex and is limited by distance.

[0004] Wireless communication: In order to realize remote monitoring and control more conveniently, the spark probe can also adopt wireless communication, such as using wireless communication technologies such as Wi-Fi, Bluetooth, Zigbee, etc. This method does not require wiring and has higher flexibility, but may be limited by signal interference and transmission distance.

[0005] Therefore, how to improve the flexibility and scalability of the fire warning system on the spark detector and reduce the cost of system wiring and maintenance has become an important issue in the current development of spark detector technology. Summary of the invention

[0006] In order to solve the above problems, the utility model discloses a spark probe with carrier communication function.

[0007] In order to achieve the above purpose, the utility model provides the following technical solutions: a spark probe with carrier communication function, comprising an infrared spark sensor, a processor, a carrier communication module and a storage module, wherein the signal output end of the infrared spark sensor is communicatively connected to the processor, and the processor respectively establishes communication connections with the carrier communication module and the storage module, and transmits an alarm signal to the control end through the carrier communication module.

[0008] In the above solution, the spark probe further includes a collection module and an independent communication module, and the signal output end of the infrared spark sensor establishes a communication connection with the independent communication module through the collection module.

[0009] In the above solution, the independent communication module establishes a communication connection with the processor.

[0010] In the above solution, the acquisition module and the independent communication module are arranged in independent housings.

[0011] In the above solution, the independent shell is located outside the shell of the spark probe.

[0012] In the above solution, the spark probe further includes a self-calibration module, and the self-calibration module is communicatively connected to the processor.

[0013] The scheme in the embodiment of the utility model uses a carrier communication module, so that after the spark is detected, an alarm signal can be quickly sent to relevant personnel, so that measures can be taken in time to prevent possible fire accidents. Carrier communication technology, as a communication method that uses existing power lines for data transmission, has the advantages of no need for additional wiring, long transmission distance, and low cost. However, most of the spark probes on the market are not equipped with carrier communication functions and cannot fully utilize existing power line resources for data transmission. At the same time, it is also equipped with a storage module that can store historical data and alarm records. This not only facilitates subsequent data analysis and accident tracing, but also provides strong data support for equipment maintenance and optimization. BRIEF DESCRIPTION OF THE DRAWINGS

[0017] In order to make the purpose, technical solutions and advantages of the utility model clearer, the utility model will be further described in detail below with reference to the accompanying drawings.

[0018] The terms used in the following embodiments are only for the purpose of describing specific embodiments and are not intended to be used as limitations on the present invention. As used in the specification and appended claims of the present invention, the singular expressions "a", "an", "above", "the" and "this" are intended to also include expressions such as "one or more", unless there is a clear contrary indication in the context.

[0019] References to "one embodiment" or "some embodiments" etc. described in this specification mean that one or more embodiments of the utility model include specific features, structures or characteristics described in conjunction with the embodiment. Therefore, the statements "in one embodiment", "in some embodiments", "in some other embodiments", "in some other embodiments", etc. that appear in different places in this specification do not necessarily refer to the same embodiment, but mean "one or more but not all embodiments", unless otherwise specifically emphasized in other ways. The terms "including", "comprising", "having" and their variations all mean "including but not limited to", unless otherwise specifically emphasized in other ways.

[0020] Example 1: Figure 1 As shown, a spark probe with carrier communication function includes an infrared spark sensor 100, a processor 200, a carrier communication module 300 and a storage module 400, wherein the signal output end of the infrared spark sensor 100 is communicatively connected with the processor 200, and the processor 200 establishes communication connections with the carrier communication module 300 and the storage module 400 respectively, and transmits an alarm signal to the control end through the carrier communication module 300.

[0021] The infrared spark sensor 100 uses infrared detection technology to monitor the spark situation in the environment in real time. When an abnormal spark is detected, the signal is quickly transmitted to the processor 200.

[0022] Specifically, it can be a high-sensitivity infrared sensor. High-sensitivity infrared sensors can detect weak sparks in time and improve safety prevention capabilities.

[0023] After receiving the signal from the infrared spark sensor 100, the processor 200 will process and analyze it to determine whether there is a safety hazard and decide whether to trigger an alarm based on a preset algorithm.

[0024] In a possible implementation, the processor 200 may use a microcontroller of the STM32 series as a processor core. A high-performance processor can process sensor data quickly and accurately, reducing the possibility of false alarms and missed alarms.

[0025] The carrier communication module 300 is responsible for remotely transmitting the alarm signal of the processor 200 to the control end through a carrier to realize remote monitoring and alarm. Specifically, a module with the same function such as an OFDM technology carrier communication module or a power line carrier communication module can be used. Carrier communication technology can realize long-distance, low-power data transmission, ensuring that the alarm signal is transmitted to the control end in a timely and accurate manner.

[0026] The storage module 400 is used to store the data analyzed and processed by the processor 200 and the alarm records, which is convenient for subsequent data analysis and troubleshooting. Specifically, a storage device such as an SD card or EEPROM can be used. The storage module can record and trace historical data, providing an important basis for safety management and accident analysis.

[0027] When the infrared spark sensor 100 detects a spark, it immediately transmits a signal to the processor 200. The processor 200 processes and analyzes the received signal and determines whether to trigger an alarm according to preset conditions. Once the alarm is triggered, the processor 200 instructs the carrier communication module 300 to send an alarm signal to the remote control terminal. At the same time, the relevant information will also be stored in the storage module 400 for subsequent analysis.

[0028] Example 2: Figure 2 As shown, based on Example 1, in order to enhance communication stability and improve the communication when the system communication is blocked or the carrier communication module 300 fails, the spark probe further includes a collection module 500 and an independent communication module 600. The signal output end of the infrared spark sensor 100 establishes a communication connection with the independent communication module 600 through the collection module 500. The independent communication module 600 establishes a communication connection with the processor 200. The collection module 500 and the independent communication module 600 are arranged in an independent housing. The independent housing is located outside the housing of the spark probe.

[0029] In this embodiment, the acquisition module 500 is responsible for real-time acquisition of the output signal of the infrared spark sensor 100 and converting it into a data format suitable for transmission and processing. Specifically, a high-precision ADC (analog-to-digital converter) chip, such as ADS1256, can be used to convert analog signals into digital signals.

[0030] The independent communication module 600 is connected to the acquisition module 500. When the main communication path (i.e., the carrier communication module 300) is blocked or fails, the independent communication module 600 can start and establish a backup communication link to ensure timely data transmission. Communication modules with multiple communication modes (such as 4G / 5G, Wi-Fi, Bluetooth, etc.) can be used, such as Huawei ME909s-821 and other 4G communication modules.

[0031] By placing the acquisition module 500 and the independent communication module 600 in independent housings and locating them outside the housing of the spark probe, electromagnetic interference that may be caused by sparks can be effectively isolated and the two modules can be protected from damage. A waterproof and dustproof housing made of metal or plastic can be used.

[0032] Under normal working conditions, the spark probe transmits data through the carrier communication module 300. When it is detected that the communication is blocked or the carrier communication module 300 fails, the acquisition module 500 will immediately start and transmit the signal of the infrared spark sensor 100 to the independent communication module 600. The independent communication module 600 then transmits the data to the control end through its backup communication link to ensure the timely transmission of the alarm signal.

[0033] Example 3: Figure 3 As shown, this embodiment further introduces a self-calibration module 700 based on the embodiment 1 or the embodiment 2 to improve the detection accuracy and reliability of the spark probe. The self-calibration module 700 is in communication connection with the processor 200 .

[0034] The self-calibration module 700 can periodically calibrate the infrared spark sensor 100 to ensure the accuracy and sensitivity of the sensor. The calibration process may include adjusting the sensor's gain, offset and other parameters to adapt to different environmental conditions and performance changes that may occur after long-term use. Exemplarily, a high-precision calibration chip or calibration algorithm can be used, such as using a dedicated calibration microcontroller (such as STC89C52, etc.) for automatic calibration.

[0035] Under normal working conditions, the spark probe detects spark conditions in the environment through the infrared spark sensor 100. At the same time, the self-calibration module 700 can trigger the calibration procedure regularly or under specific conditions to calibrate the infrared spark sensor 100. After the calibration is completed, the calibration parameters will be passed to the processor 200 so that the processor can perform more accurate analysis and judgment based on the calibrated sensor output.

[0036] A communication connection is established between the self-calibration module 700 and the processor 200 to exchange data and instructions during the calibration process. This communication connection can be implemented in a wired or wireless manner, depending on the system design and actual application requirements.

[0037] The technical means disclosed in the solution of the utility model are not limited to the technical means disclosed in the above-mentioned implementation mode, but also include technical solutions composed of any combination of the above technical features. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the principle of the utility model, and these improvements and modifications are also regarded as the protection scope of the utility model.
