Description

Technical Field

[0001] The utility model relates to the technical field of fire monitoring, in particular to a portable voice debugging device for a CAN measurement and control system of an underground pipe gallery. Background Art

[0002] In the construction of modern smart cities, underground pipe gallery construction is an important one. For each section of underground pipe gallery with a length of dozens or even hundreds of kilometers distributed in different areas of the city, a "monitoring system" must be built to ensure the safe operation of various equipment in the section, including the installation, operation, maintenance and fault diagnosis of a large number of measurement and control equipment.

[0003] The monitoring and execution equipment in each section of the underground corridor form the industrial Internet of Things of the CAN bus. The measurement and control information is displayed graphically and tracked in real time in the corridor control center using configuration software. However, the installation and operation and maintenance personnel need effective information tools to repair and debug the CAN measurement and control system in the underground corridor far away from the corridor control center. At present, the installation and maintenance personnel can only use laptops and CAN packet capture debugging tools and AC power supplies on the market, manually type commands on the keyboard, and perform debugging and maintenance by looking at the captured packet data displayed on the screen and the actions of the repaired and debugged equipment, which is extremely inconvenient. Utility Model Content

[0004] The utility model aims to provide a portable voice debugging device for an underground pipe gallery CAN measurement and control system, which can facilitate maintenance and debugging of the CAN measurement and control system in the underground pipe gallery on the ground.

[0005] In order to achieve the above purpose, the utility model provides the following technical solutions:

[0006] A portable voice debugging device for an underground pipe gallery CAN measurement and control system comprises a voice module, a processor with a CAN controller, a CAN transceiver, an Ethernet module and a battery power supply, wherein the voice module comprises a voice chip, a speaker and a microphone, the speaker and the microphone are both electrically connected to the voice chip, the battery power supply is electrically connected to the processor and the voice chip of the voice module, and the voice module, the Ethernet module and the CAN transceiver are all electrically connected to the processor.

[0007] In the above scheme, the microphone is used to pick up the voice signal emitted by the staff, the voice chip is used to parse the voice signal to obtain the voice command code, and transmit the obtained voice command code to the processor, the processor converts the voice command code into a CAN data frame, and the CAN data frame is sent through the CAN transceiver so as to be received by the CAN measurement and control system. The processor is also used to convert the CAN response data frame received by the CAN transceiver into a device response code and output it to the voice chip, which is parsed into voice information by the voice chip and played through the speaker.

[0008] When using the above-mentioned portable voice debugging device, the staff does not need to go deep into the tunnel. Through the voice debugging device installed in the tunnel control center, they can directly conduct voice conversations with the voice debugging devices installed in each tunnel section, monitor and control the equipment in each section, and debug and maintain the measurement and control equipment through voice conversations, which greatly facilitates the operation and maintenance of the tunnel.

[0009] In one possible implementation, the voice chip is a W02x-M-36P chip, whose MIC+ pin and MIC- pin are connected to a microphone, and whose SPK+ pin and SPK- pin are connected to a speaker. The W02x-M-36P chips can communicate with each other, ensuring the feasibility and stability of voice debugging.

[0010] Further optimized, the 5V_IN pin of the W02x-M-36P chip is connected to a 5V power supply through a first capacitor and a second capacitor connected in parallel, and its 3V3_OUT pin is connected to a 3.3V power supply through a third capacitor. In this solution, filtering is performed at the power input end through a capacitor, which can ensure the stability of the input voltage, thereby making the entire debugging device stable and reliable.

[0011] In one possible implementation scheme, the Ethernet module uses a LAN8720A chip, whose XTAL2 pin is connected to a crystal oscillator source, and both ends of the crystal oscillator source are grounded via a capacitor.

[0012] Further optimized, the TXP pin, TXN pin, RXP pin, and RXN pin of the LAN8720A chip are connected to a 3.3V voltage through a filter resistor, and its VDD1A pin, VDD2A pin, VDDIO pin, and VDDCR pin are connected to a 3.3V voltage through a filter capacitor. In this solution, filtering at the power input end through a resistor or capacitor can ensure the stability of the input voltage, thereby making the entire debugging device application stable and reliable.

[0013] Optionally, the battery power source is a 5V lithium-ion battery. In this solution, the 5V lithium-ion battery can be charged and recycled, and does not need to be connected to an alternating current, greatly simplifying the circuit layout.

[0014] Optionally, the processor is an ARM chip.

[0015] In specific application, there are multiple portable voice debugging devices, one of which is configured in the tunnel control center, and the rest are configured in multiple tunnel sections, and one portable voice debugging device is configured in each tunnel section.

[0016] Compared with the prior art, the utility model has the following technical advantages: it reduces the work intensity of underground pipe gallery operation and maintenance personnel under complex and harsh conditions, greatly improves work efficiency; it reduces the cost of operation and maintenance work, and effectively improves the working environment.

It should be understood that the specific embodiments described here are only used to explain the utility model and are not used to limit the utility model.

[0025] See also Figure 1The portable voice debugging device for the underground pipe gallery CAN measurement and control system provided in this embodiment includes a voice module, a processor with a CAN controller, a CAN transceiver, an Ethernet module and a battery power supply, wherein the battery power supply is electrically connected to the processor and the voice module to directly provide power thereto, and the voice module, the Ethernet module and the CAN transceiver are all electrically connected to the processor.

[0026] The battery power source preferably adopts a rechargeable battery to support continuous power supply, for example, a 5V lithium-ion battery can be used. A dry cell battery can also be used.

[0027] The voice module includes a voice chip, a speaker and a microphone. The speaker and the microphone are electrically connected to the voice chip, and the battery power supply is electrically connected to the voice chip. The voice chip is electrically connected to the processor via RS-232. The microphone is used to pick up the voice signal emitted by the staff, and the voice chip is used to parse the voice signal to obtain the voice command code, and transmit the obtained voice command code to the processor. The processor converts the voice command code into a CAN data frame, and the CAN data frame is sent through the CAN transceiver so as to be received by the CAN measurement and control system. The processor is also used to convert the CAN response data frame received by the CAN transceiver into a device response code and output it to the voice chip, which is parsed into voice information by the voice chip and played through the speaker.

[0028] See also Figure 2 As an example of a possible implementation method, the electrical circuit diagram of the voice module is as follows Figure 2 As shown. The voice chip uses the W02x-M-36P chip of Shanghai Huwen Technology Co., Ltd. Its 5V power input pin 5V_IN is connected to the 5V power supply through the second capacitor C2 and the first capacitor C1 connected in parallel, and its 3.3V power input pin 3V3_OUT is connected to the 3.3V power supply through the third capacitor C3. Filtering is performed through capacitors C2, C1, and C3 to ensure the stability of the input voltage. The MIC+ pin and MIC- pin of the W02x-M-36P chip are connected to the microphone MK1, and its SPK+ pin and SPK- pin are connected to the speaker LS1.

[0029] The Ethernet module mainly exchanges information with the sensing device (the measurement and control device being debugged or maintained), uploads the response information of the sensing device to the tunnel control center, or sends the measurement and control commands issued by the tunnel control center to the sensing device. Figure 3a and Figure 3bAs an example of an implementable method, the Ethernet module uses the LAN8720A chip, and its TXP pin, TXN pin, RXP pin, and RXN pin are connected to the 3.3V voltage through a filter resistor, and its VDD1A pin, VDD2A pin, VDDIO pin, and VDDCR pin are connected to the 3.3V voltage through a filter capacitor, respectively. The input voltage is filtered by a capacitor resistor to ensure the stability of the voltage. Its XTAL2 pin is connected to the crystal oscillator source Y3, and the two ends of the crystal oscillator source Y3 are grounded through a capacitor (C29, C30). RJ45 is an Ethernet interface, and the LAN8720A chip is connected to the corresponding pins of the ARM chip.

[0030] When the portable voice debugging device is used, one portable voice debugging device is installed in the tunnel control center and in each tunnel section. The staff can communicate directly with the voice debugging device in each tunnel section through the voice debugging device installed in the tunnel control center, monitor and control the equipment in each section, and debug and maintain the measurement and control equipment through voice dialogue, which greatly facilitates the operation and maintenance of the tunnel. Figure 4 In the corridor section, the corridor control gateway 30 and the measurement and control equipment 10 are both connected to the CAN bus, and the Ethernet module of the portable voice debugging device 20 is connected to the corridor control gateway 30 and communicates with the corridor control center via Ethernet.

[0031] When the portable voice debugging device is used for debugging, the staff sends out the voice signal of the CAN measurement and control command at the tunnel control center. The voice chip of the portable voice debugging device converts the voice signals of the various CAN measurement and control commands picked up into the corresponding voice command code and outputs it to the processor ARM chip. The ARM chip converts it into a CAN data frame and sends it to the CAN measurement and control system through the CAN transceiver. When the designated tunnel sensing device in the CAN measurement and control system responds to the measurement and control command and acts, the portable voice debugging device installed in the tunnel section converts the response code of the new state of the tunnel sensing device into a CAN response data frame and sends it to the CAN measurement and control system. The CAN transceiver receives the CAN response data frame and transmits it to the ARM chip. The ARM chip converts the CAN response data frame into a device response code and transmits it to the voice chip, and outputs the voice information through the speaker.

[0032] The above-described embodiments are only specific implementation methods of the present utility model, but the protection scope of the present utility model is not limited thereto. Any technician familiar with the technical field can easily think of various equivalent modifications, replacements and improvements within the technical scope disclosed by the present utility model, and these modifications, replacements and improvements should be included in the protection scope of the present utility model. Therefore, the protection scope of the present utility model shall be based on the protection scope of the claims.
