[0025] The present invention will be further described below in conjunction with the accompanying drawings.

[0026] refer to Figure 1As shown, one embodiment of the present invention is a multifunctional lamp pole controller based on the Internet of Things, the controller includes a control acquisition mainboard and a routing gateway mainboard, and the control acquisition mainboard is also connected to a power module. And the routing gateway mainboard is connected to the power module through the control acquisition mainboard. Figure 2 As shown, the aforementioned control acquisition mainboard includes a microprocessor module, which is respectively connected to the pin signal interface, switch signal input terminal and communication interface placed on the control acquisition mainboard. Figure 3 As shown, the routing gateway mainboard includes a wireless network module, an Ethernet module and a WIFI module, and the wireless network module, the Ethernet module and the WIFI module are respectively connected to the Linux core board, and the Linux core board is connected to the microprocessor module in the control acquisition mainboard through the communication interface.

[0027] Based on the above circuit module structure, combined with Figure 4 As shown, it is used for the microprocessor module to perform self-test after the control acquisition mainboard is powered on, and the control routing gateway mainboard is powered on after the self-test passes. An abnormal listening thread protocol is built into the microprocessor module, which is used for the microprocessor module to obtain the abnormal log and operation log after the routing gateway module mainboard is powered on and running through the abnormal listening thread protocol. The Linux core board is built-in with a network service thread protocol, and the network service thread protocol provides a local network communication thread and a WIFI wireless thread to the outside. The local network communication thread is used to communicate with the microprocessor module of the control acquisition mainboard, and the microprocessor module transmits the currently monitored abnormal log data and the data collected by the sensor device to the platform server through the local network communication thread. The WIFI wireless thread provides a WIFI hotspot to the outside.

[0028] Preferably, the Linux core board is connected to the network port of the mounting device through the network service thread protocol. On this basis, the aforementioned network port of the mounting device is connected to the LED display device and the video surveillance device. The network port of the mounting device is also connected to the expansion submodule device, such as the one-button alarm device, emergency broadcast, 77G millimeter wave radar and charging pile, etc., which are the mainstream external equipment facilities that can be integrated on the smart lamp pole. And the aforementioned expansion submodules are all connected to the microprocessor module in the control acquisition mainboard through the communication interface.

[0029] Through the above module expansion, the smart lamp pole can realize one-click alarm and help, emergency broadcast, vehicle and personnel distance and flow monitoring, and new energy vehicle charging. The expansion module communicates with the server through the network port of the routing gateway motherboard to ensure the interaction between the expansion module and the platform, and the expansion module and the control acquisition motherboard use RS232 / RS485 communication interface for board-level communication, ensuring centralized monitoring and management of local device status.

[0030] In this embodiment, by integrating the control acquisition mainboard and the routing gateway mainboard in the controller, the control acquisition mainboard can obtain the abnormal log and operation log after the gateway module mainboard is powered on, and then monitor the operation status of various external facilities connected to the routing gateway module in the smart lamp pole, and transmit the abnormal log to the platform server through the routing gateway module. The control acquisition mainboard can also obtain the signal data collected by each sensor on the sensor mainboard through the pin signal interface, and feed it back to the platform server after being processed by the microprocessor module in the control acquisition mainboard, so as to realize the use of a controller to monitor and control all equipment and facilities on the smart lamp pole, which is convenient for management and information interaction between the smart lamp pole and the unified smart city management platform.

[0031] The multifunctional lamp pole controller based on the Internet of Things mentioned in the above embodiments is a centralized control device mainly developed for intelligent multifunctional poles, with multiple functions such as remote switch control, voltage and current monitoring of each circuit, active alarm, dimming control output, switch signal monitoring and alarm, autonomous routing, WIFI hotspot, environmental integrated sensor, LED screen display, video monitoring, etc. The Ethernet interface of the LED display module and the video monitoring module and the device routing gateway motherboard is connected to communicate with the cloud server. The acquisition control motherboard monitors the system operation status of the LED display module and the video monitoring module and the voltage and current of each module by communicating with the routing gateway, ensuring the timely and accurate active reporting of various abnormal events, and providing timely data support for system managers.

[0032] Refer to Figure 2 and Figure 5As shown, in order to facilitate the control acquisition mainboard to collect the operation data of the equipment and facilities on the smart lamp pole and the external environmental data, in another embodiment of the present invention, a control acquisition thread can also be preset in the microprocessor module in the control acquisition mainboard, and the microprocessor module is connected to the pin signal interface through the control acquisition thread. For example, a pin signal interface in the form of a PGA interface, an ADC interface, a DEC interface, and an EMU interface. Based on the aforementioned design ideas, the aforementioned pin signal interface can be directly connected to the sensor mainboard. The sensor mainboard belongs to the external equipment facilities of the above-mentioned multifunctional lamp pole controller, which mainly includes a microcontroller. The microcontroller is connected to the pin signal interface signal through its own communication interface (such as RS485 / 232 and other bus interfaces), and the aforementioned microcontroller is also connected to multiple different types of sensors, such as three-axis direction sensors, carbon dioxide sensors, noise sensors, atmospheric pressure sensors, temperature and humidity sensors, light intensity sensors and PM2.5 / PM10 data acquisition sensors. The microprocessor is used to transmit the data collected by each sensor through the communication interface and the pin signal interface, and the control acquisition thread transmits the data to the microprocessor module in the control acquisition mainboard. The data collected by the aforementioned sensors can be transmitted to the platform server through the local network communication thread of the routing gateway mainboard through the microprocessor module. As Figure 5 As shown, the sensor mainboard mainly adopts a mechanism of centralized processing of digital and analog signals. Its device hardware interface is 485 bus and the protocol is the standard MODBUS protocol, which ensures compatibility with other devices.

[0033] Furthermore, similar to the design concept of similar controller products, the aforementioned control acquisition mainboard is also provided with eight control output circuits and three voltage input circuits, and all are connected to the microprocessor module. In addition, the above-mentioned power supply module is a battery unit, and the microprocessor module is connected to the battery unit through the automatic power switching unit. At the same time, the control acquisition mainboard is also provided with a local clock unit and an acceleration sensor, and the acceleration sensor and the local clock unit are both connected to the microprocessor module, and the local clock unit is used to keep the time of the control acquisition mainboard consistent with the remote platform server, and the acceleration sensor is used to measure the bevel inclination of the controller, etc. As can be seen from the above, the control acquisition mainboard mainly monitors each module from two aspects: one is the voltage and current information of the hardware monitoring device. The second is to monitor the module system operation log.

[0034] The above hardware monitoring equipment adopts a voltage and current acquisition solution with a precision of 0.2. The platform server will set the alarm threshold according to the rated voltage and current of the device connected to the controller. The operation of the controller can monitor the relevant parameters in real time and generate alarm information of current over-limit (upper and lower limits) and voltage over-limit, and can provide the active power data of the external devices connected to each circuit of the controller. The log listening part is that the device does not reflect the abnormality of electrical data in the hardware part (voltage and current are both within the normal threshold), but the system operation log of the device shows that the system has been constantly resetting or prompts that some functions are abnormal. The controller will also promptly and actively report the abnormal log to the remote platform server. At the same time, local emergency processing is carried out (such as current over-limit will shut down the power supply of the abnormal circuit). It reduces the investment expenditure of later manual maintenance, improves the processing response speed of faulty equipment maintenance, and provides necessary data support for maintenance personnel.

[0035] refer to Figure 3 and Figure 4 As shown, in a more preferred embodiment of the present invention for solving the technical problem, in order to ensure the effectiveness of network transmission, the network service thread protocol includes an Ethernet network thread and a 4G network thread, which are used to control the microprocessor module in the acquisition mainboard to communicate with the external device through the Ethernet network thread under normal circumstances, and the 4G network thread is suspended. When the Ethernet network thread is in the exception handling stage, the microprocessor module in the acquisition mainboard communicates with the external device through the 4G network thread.

[0036] After the network service is enabled, the gateway will simultaneously enable the service thread based on 4G wireless and the service thread based on Ethernet, which ensure the establishment of the physical link channel. When both Ethernet and 4G physical links are available, the communication link based on Ethernet is preferred, and the 4G thread is in a suspended state. When Ethernet cannot guarantee the physical link normally, the 4G thread will resume the running state, and the Ethernet thread will handle the exception handling stage. Ethernet usage has a higher priority than 4G wireless.

[0037] refer to Figure 4 As shown, another embodiment of the present invention is a multifunctional lamp pole control method based on the Internet of Things, the method comprising the following steps:

[0038] Step S1, after the control acquisition mainboard is powered on, the microprocessor module performs a self-check, and after the self-check passes, the control routing gateway mainboard is powered on.

[0039] Step S2: The microprocessor module in the control acquisition mainboard obtains the abnormal log and operation log of the routing gateway module mainboard after it is powered on through the abnormal listening thread protocol.

[0040] Step S3: The network service thread protocol built into the Linux core board in the routing gateway module mainboard provides a local network communication thread to the outside, and the microprocessor module transmits the currently intercepted abnormal log data to the platform server through the local network communication thread.

[0041] Step S4, the microprocessor in the sensor mainboard transmits the data collected by each sensor to the microprocessor module in the control acquisition mainboard through the communication interface and the pin signal interface, and the microprocessor module transmits the data to the platform server through the local network communication thread. Similar to the above embodiment, in this step, the aforementioned sensors include a three-axis direction sensor, a carbon dioxide sensor, a noise sensor, an atmospheric pressure sensor, a temperature and humidity sensor, an illumination sensor, and a PM2.5 / PM10 data acquisition sensor.

[0042] As Figure 4 As shown, in addition to the expansion sub-module equipment, LED display equipment and video surveillance equipment, in the entire power supply system, except for controlling the acquisition mainboard to be in a long power supply state, the power supply of other equipment can be controlled on and off by the mainboard.

[0043] After the control acquisition mainboard is powered on, the system resets and then enters the hardware self-test phase. If the test fails, the system will reset again (mainly to test the status of peripheral chips on the board).

[0044] After the detection is successful, the system enters the running state, controls the acquisition mainboard to power on the gateway mainboard, analyzes and processes the gateway operation log through the "abnormal listening processing thread", and sets the corresponding status flag.

[0045] After the gateway device is powered on, the system is reset first, and then the hardware resources are detected. If the hardware is normal, the thread of starting the network service is entered. If the hardware resource detection fails, the device will output an abnormal log and automatically reset the gateway system.

[0046] After the network service is enabled, the gateway will simultaneously enable the service thread based on 4G wireless and the service thread based on Ethernet, which ensure the establishment of the physical link channel. When both Ethernet and 4G physical links are available, the communication link based on Ethernet is preferred, and the 4G thread is in a suspended state. When Ethernet cannot guarantee the physical link normally, the 4G thread will resume the running state, and the Ethernet thread will handle the exception handling stage. Ethernet usage has a higher priority than 4G wireless.

[0047] After the physical link is successfully established, the network service thread will configure the internal parameters (such as the internal IP address switch domain, the establishment of the Socket of the "local communication network thread", IP address filtering, etc.), and then provide the data service function of the LAN port. At the same time, the WIFI wireless thread is started, and after the unnecessary configuration process, the WIFI hotspot service function can be provided.

[0048] For each connected LED module, video module, and expansion module, when the Socket link is established, a "log listening task" will be started in the network service thread to capture and extract the output log of the device, and output the log data information through the operation log window of the gateway. (The log listening task mainly extracts data based on the log output protocol provided by the manufacturer of the LED display module and video surveillance equipment. Even if the target device is in a network-free state, the device can still analyze the log locally and take corresponding processing measures).

[0049] In addition to monitoring LAN-based devices, the control acquisition mainboard is also responsible for collecting and processing the three-phase voltage, eight-circuit working current, switch signal and sensor signal of the equipment, and provides functions such as loop output, dimming output, local parameter setting, local forced control, and device operation mode switching. Data is transmitted to the platform server through the "local communication network thread".

[0050] By analyzing the collected data, the device provides over-temperature alarm, switch quantity alarm, abnormal current alarm, abnormal voltage alarm, abnormal switch light alarm, etc. (For specific functions, please refer to the function description below).

[0051] The LED display module, video display module and external expansion module are directly connected to our "Smart City Integrated Information Management Platform", including the relevant interface interfaces of uplink and downlink communications, data frame structure, database implementation, etc., to achieve unified remote management of each terminal device.

[0052] Based on the above-mentioned embodiment of the present invention, the multifunctional lamp pole controller monitors the power supply system of each independent module with an effective value accuracy better than 0.2%. Figure 4 As shown, the routing gateway can monitor and analyze the operation logs of each device and perform corresponding exception processing.

The same expression appearing in multiple places in the specification does not necessarily refer to the same embodiment.
