Description

Technical Field

[0001] The invention belongs to the technical field of building materials, and in particular relates to an automatic spraying maintenance system. Background Art

[0002] The machine-made sand produced by tunnel ballast processing is mainly affected by the properties of tunnel ballast. Its hardness index may fluctuate greatly, which has a great impact on the wear of the crushing equipment, especially the crushing effect of the medium crushing cone. The production control system is required to detect the equipment status in real time and adaptively adjust the production line process. In addition, there are two main processes for the production of machine-made sand: dry process and wet process. The parent rock, which is mainly tunnel ballast, has a low mud content and is suitable for dry sand making. In the process of dry sand making, a large amount of dust is inevitable. It is necessary to set up reasonable dust collectors and water atomization dust reduction equipment, and use intelligent control systems to flexibly start and stop according to the amount of dust, so as to save energy while meeting environmental protection standards.

[0003] Construction site dust pollution is the unorganized particulate matter pollution emitted during the construction process, including both primary dust caused by various construction links within the construction site and secondary traffic dust caused by construction transport vehicles carrying mud and building materials escaping on the roads outside the construction site. For a long time, the air quality supervision caused by construction site dust has been a great problem for government regulatory departments because of the inability to obtain real-time monitoring data or the inability to obtain direct data corresponding to the facts after receiving reports.

[0004] In order to carry out green projects, quality projects and safety projects, construction sites are basically equipped with sprinklers, fog cannons and various cleaning devices. However, in actual use, they are basically all turned on and off manually or by remote control. This is time-consuming, labor-intensive, inconvenient to operate, and easily wastes resources.

The normally closed contact of the relay is connected to the 5V input voltage, the normally open contact is grounded, and the output terminal of the relay is connected to the input terminal of the optocoupler isolation chip TLP523-4 through a resistor; when AC220V is input to the relay at the output terminal of the circuit breaker, the normally closed contact of the relay is disconnected, the normally open contact is closed, the input level of the optocoupler isolation chip changes from 5V to 0V, the output terminal of the optocoupler isolation chip is turned on, and the I / O port voltage of the MCU is pulled up to 3.3V, thereby detecting that the contactor is closed.

[0027] In order to make the purpose, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments.

[0028] The automatic sprinkler maintenance system described in this embodiment includes three parts: an environmental monitoring unit, a data transmission unit, and an environmental early warning intervention unit;

[0029] The interaction between each sensor and the terminal device in the environmental monitoring unit is realized through the data transmission unit, and the changes in the monitored environment are realized through the environmental early warning intervention unit.

[0030] The environmental monitoring unit includes a terminal device, an LED display screen, a dust removal device, a temperature sensor, a humidity sensor, a wind force / wind speed sensor, and a PM2.5 / PM10 sensor. The temperature, humidity, wind force / wind speed, PM2.5, and PM10 of the surrounding environment are measured in real time by each sensor, and the above data are collected and transmitted to the terminal device; the terminal device interacts with each sensor, LED display screen, and dust removal device for data exchange respectively;

[0031] The data transmission unit includes DTU and NB-IoT base station; the environmental early warning intervention unit is a network cloud server.

[0032] like Figure 1 The figure shows the structure of the data transmission unit. The NB-DTU receives the data frame of the RS485 communication link sent by the terminal device, encapsulates the data in the NB-DTU's MCU according to the data format requirements of the NB-IoT module, and sends it to the NB-IoT base station through the NB-IoT module. After the base station receives the data, it forwards the data to the network cloud server according to the destination server address in the data protocol, completing a data reporting process. The data sending process is the opposite of the reporting process. First, the network cloud server sends the data to the NB-IoT base station. The base station forwards the data to the corresponding NB-IoT module according to the target address in the data protocol, and enables the module to generate a read request signal to notify the NB-DTU's MCU to read the data. After the MCU reads and parses the data, it sends the data to the terminal device through the RS485 interface circuit, completing a data sending process.

[0033] In the data transmission and reception process, the data packaging and parsing processes are completed by the NB-DTU's MCU and the NB-IoT base station, which is completely transparent to the user. In addition, NB-IoT is built on a cellular network and consumes only about 180KHz of bandwidth. It can be directly deployed on a GSM network, UMTS network or LTE network, reducing deployment costs and achieving efficient transmission. NB-IoT supports cellular data connections for low-power devices in wide area networks, supports long standby times, provides efficient connections for devices with high network connection requirements, and can achieve long-term and stable data transmission. It can significantly reduce terminal power consumption and ensure stable data collection. Figure 3 As shown, the network bidirectional data transparent transmission DTU includes MCU, NB-IoT module, voltage stabilizing circuit module and RS485 communication interface; NB-IoT module, voltage stabilizing circuit module and RS485 communication interface are all connected to MCU; in circuit design, MCU's control over NB-IoT modules and data transmission are the core of the entire design.

[0034] The MCU uses the STM32F103C8T6 microcontroller with the Cortex-M3 core; the NB-IoT module uses the BC26 module. In addition to the power supply interface, the BC26 module hardware also includes 1 USIM card interface, 3 UART interfaces, 1 SPI interface, 1 PSM_EINT interface for external interrupt wake-up, 1 10-bit ADC interface, 1 antenna interface, as well as reset, power-on, and networking indication interfaces. In its OpenCPU version, it also includes an I2C interface, an I2S interface, and a configurable GPIO interface. The three UART interfaces are the main UART, debug UART, and auxiliary UART interfaces. Both the main UART and the auxiliary UART can be used for communication with the MCU. In addition, the main UART can also be used for BC26 firmware upgrades. The debug UART can output debugging information for software debugging. This design uses the main UART to transmit data with the MCU. Since the voltage level of the main UART is 1.8V, an external voltage conversion circuit must be added when communicating with the MCU. The specific voltage conversion circuit is as follows Figure 4 As shown, it is a conventional 1.8V to 3.3V voltage conversion circuit.

[0035] like Figure 5 As shown in the figure, the power module is implemented with the DC / DC power chip TPS54202, which is a 2A synchronous buck converter with an input voltage range of 4.5 to 28V. It contains two integrated switching field effect transistors and has internal loop compensation and internal soft-start functions. TPS54202 has high power density and small package, and only requires very few external components to achieve stable voltage output, which is very suitable for the design of circuits with volume requirements.

[0036] The VIN port of the power chip is connected to the external input port VIN, and two input filter capacitors C6 and C7 are connected in parallel between the VIN port and the external input port VIN, and the other ends of the input filter capacitors C6 and C7 are both grounded;

[0037] The GND port of the power chip is grounded;

[0038] The BOOST port of the power chip is connected to the capacitor C1, and the other end of the capacitor C1 is connected to the inductor L1;

[0039] The SW port of the power chip is connected to one end of the inductor L1;

[0040] A capacitor C2 and a resistor R1 are connected in parallel between the FB port of the power chip and the other end of the inductor L1. One end of the resistor R2 is grounded, and the other end is connected to the resistor R1, the FB port, and the capacitor C2. R1 and R2 are feedback resistors that provide a voltage reference for the TPS54202.

[0041] One end of the inductor L1 away from the SW port is connected in parallel with output filter capacitors C3, C4, and C5, and C3 also has an energy storage function. The other ends of the capacitors C3, C4, and C5 are grounded.

[0042] When R1 is 100kΩ and R2 is 22.1kΩ, the circuit output voltage is 3.3V. Capacitors C3, C4, and C5 are output filter capacitors, and C3 also has an energy storage function to improve the stability of the power supply output.

[0043] The STM32F103C8T6 has three serial interfaces in total. Serial port 1 is used to realize the reception and transmission of RS485 data, and the reception and transmission of RS485 data is realized by SP3485; Serial port 2 transmits data between the NTB0102DP chip and the main UART of BC26, and the main UART of BC26 is the level standard of 1.8V, while the serial port of MCU is the level standard of 3.3V. Therefore, when designing, it cannot be directly connected and must be connected through a level conversion chip. TI's NTB0102DP is selected in the design. The reception and transmission of RS485 data is realized by SP3485. Through this circuit, the mutual conversion between differential RS485 data and single-ended LVTTL level UART data can be realized.

[0044] The network cloud server stores and processes the received sensor data, determines whether there is data exceeding a threshold, and if there is a value exceeding the threshold, sends a control signal, transmits it to the terminal device through the data transmission unit, and starts the dust removal device.

[0045] The dust removal equipment adopts a spraying device, including a spraying device on a fog cannon truck, a spraying device on the top of a workshop, and a spraying device on a green belt;

[0046] The technical principle of the spraying of the fog cannon truck is to pressurize the water by high air pressure, and input it into the high-pressure nozzle atomization device through the pipeline to form a water mist floating in the air. The water mist is sent to a longer distance by the spraying system. The water mist can absorb fine dust and suspended particles in the air within a certain space, thereby achieving dust reduction. The emergence of the fog cannon truck has a significant effect on the control of dust, and the content of large particles in the air will be reduced. The fog cannon truck has high working efficiency and fast spraying speed. When spraying dust reduction on work scenes that are prone to dust, the sprayed particles are small. When the particles come into contact with dust, they will become a wet mist, which can quickly suppress dust reduction. Not only that, the supporting power is also very flexible. It can be powered by three 380V mains electricity or a diesel generator set. It is very flexible to operate, safe, stable and reliable to use. It can be remotely controlled or manually operated. It can arbitrarily control the horizontal rotation spray angle and water consumption. Compared with other dust suppression spraying equipment (such as spray guns, sprinkler locomotives, etc.), it can increase efficiency by 70% to 80%. And the water mist coverage area is much larger than other dust suppression spraying equipment.

[0047] The main purpose of the workshop top spraying is to prevent the dust in the production workshop from overflowing outside the factory building, and directly control the dust in the workshop, which is used to reduce dust in the production workshop and prevent dust from overflowing. The spacing between the sprinkler heads is 3m, and they are arranged with each span of the steel structure beam. The system uses PE pipes or PPR pipes as pressurized water delivery pipes, and the pipes are connected by hot melt welding to prevent the cracking of the connectors caused by hard connections. The sprinkler adopts a three-nozzle high-pressure atomizing sprinkler.

[0048] Green belt spraying is a kind of spraying on green plants to achieve the purpose of dust reduction and haze removal and watering plants.

[0049] The opening and closing of the start switch of the spray device of the fog cannon vehicle is realized by the on-off of GPIO in the ARM hal library protocol. Considering that the spray device of the fog cannon vehicle needs to be powered by AC220 / 380V and the on-site power supply is unstable, the control connection is to set a series of safety protection measures, and the disconnection and closing of the large circuit are realized through the isolation control of the intermediate relay.

[0050] When the sensor detects abnormal PM2.5 at the gravel making site, the remote control technology can be used to quickly turn on the fog cannon device to reduce the PM2.5 level at the gravel making site. When remote power off is required, the backend server sends a control disconnection command to the designated terminal, and the circuit breaker outputs DC24V or AC220V voltage to the input terminal of the intermediate relay, and the intermediate relay controls the contactor to disconnect.

[0051] The opening and closing of the sprinkler device is realized by a relay, such as Figure 5As shown; the output voltage of the circuit breaker is connected to the input terminal A1 of the AC relay RJ1S-CL-A110, the normally closed contact of the relay is connected to the 5V input voltage, the normally open contact is grounded, and the output terminal of the relay is connected to the input terminal of the optocoupler isolation chip TLP523-4 through a resistor; when AC220V is input to the relay port B at the output terminal of the circuit breaker, the normally closed contact of the relay is disconnected, the normally open contact is closed, the input level of the optocoupler isolation chip changes from 5V to 0V, the output terminal POWER-T of the optocoupler isolation chip TLP523-4 is turned on, and the I / O port voltage of the MCU is pulled up to 3.3V, thereby detecting that the contactor is closed.

[0052] In summary, the present invention measures the surrounding environment information in real time through various sensors and transmits it to the terminal device. The environmental warning intervention unit is a network cloud server; the DTU receives the data frame of the RS485 communication link sent by the terminal device, and sends it to the NB-IoT base station through the NB-IoT module; after the base station receives the data, it forwards the data to the network cloud server according to the destination server address in the data protocol; the network cloud server sends the data to the NB-IoT base station, and the base station forwards the data to the corresponding NB-IoT module and causes the module to generate a read request signal, notifying the MCU of the DTU to read the data; after the MCU reads and parses the data, it sends the data to the terminal device through the RS485 interface circuit. According to the surrounding environment monitored by the sensor, the present invention transmits the relevant data to the system platform in real time through the Internet of Things, and automatically associates with the dust removal equipment, and then performs related equipment operations to realize unmanned automatic management.
