Description

Technical Field

[0001] The utility model belongs to the field of water conservancy projects, and in particular relates to a touch-type gate opening sensor. Background Art

[0002] The gate level meter is a device for measuring the gate opening. The gate opening measurement is very important in reservoirs, sluices, ship locks, hydropower stations and other occasions, affecting the staff's scheduling decisions on water conservancy projects. Therefore, the industry has high requirements for the real-time, accuracy, and durability of gate opening measurement. The gate level meter usually has a precise speed change and measurement structure inside, and can transmit the measurement results to display instruments, PLCs, control center servers and other equipment, integrating measurement and communication functions.

[0003] The most traditional gate level meter is basically a purely mechanical structure, which uses mechanical rotary encoders, pull-rope displacement sensors, etc. to measure the gate opening value. Its measurement principle is mainly based on a certain specific mechanical structure for pure physical connection, and then uses mathematical calculations to obtain the measured value.

[0004] With the improvement of infrastructure automation and the vigorous development of Internet of Things technology, the industrial control industry has higher requirements for sensors. In recent years, instruments and meters for measuring gate positions that are improved on traditional mechanical encoders have gradually appeared on the market, but the existing instruments and meters are simple and straightforward superpositions of mechanical gate position meters, display screens, single-chip microcomputers, communication interfaces and other components, with low intelligence, and the overall functions are basically limited to traditional sensors, except that the measurement data can be transmitted to PLC, servers, display instruments and other equipment by connecting communication cables. Although it has improved compared to before, it is not convenient to install and use, and the increase of on-site cables has more or less created some safety hazards.

[0005] At the same time, because the current gate level meter generally adds communication functions, there is a need to configure the serial port communication address, baud rate and other parameters of the gate level meter. Some companies develop their own host computer software, use the serial port of the sensor to connect to the computer, and then use the host computer software on the computer to set and debug parameters. Although the traditional host computer software has improved the functions of the gate level meter, the steps are still somewhat complicated for most monitoring units. When the gate level meter fails or unknown problems occur during the use of the gate level meter, the monitoring unit needs to contact the manufacturer of the gate level meter and wait until they go to the site and connect the equipment with a communication cable before providing corresponding technical support, which has a high maintenance cost; at the same time, for the monitoring unit, it must wait for the technical support personnel to arrive at the site before repairing the equipment, which will also bring certain safety hazards.

[0006] In addition, the traditional gate level meter is a purely mechanical structure, which needs to be connected to instruments such as gate opening meters through serial ports or other means to display. At present, some improved gate level meter products on the market are equipped with display screens, but their functions are generally relatively simple, and they can only passively receive communication fragments between encoders and other devices to display current data.

[0019] The technical solutions in the embodiments of the present invention are described clearly and completely below. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0020] See also Figure 1 Combination Figure 2-Figure 3 As shown, the embodiment of the utility model includes:

[0021] A touch-type gate opening sensor is mainly used in the field of water conservancy projects to measure the gate opening of water conservancy projects such as rivers, lakes, and reservoirs. The sensor comprises a housing 1, a coding disk 2, a panel 3, a rotating shaft 4, a sleeve 5, a main board 6, a touch LCD screen 7, a lithium battery, a power cord, and an antenna 8.

[0022] The shell 1 is a hollow rectangular parallelepiped structure with an opening on the top and a panel 3 installed thereon. The shell 1 and the panel 3 are customized with a high protection grade material and an integrated body design.

[0023] The touch LCD screen 7 is fixed on the panel 3. The touch LCD screen 7 adopts a 2.4-inch color LCD screen, which is a capacitive touch screen. The UI human-computer interaction can not only display the gate opening value, gate status and other information in real time, which is convenient for on-site staff to view, but also supports users to directly configure parameters by clicking on the screen, making the configuration process clear and intuitive, and the probability of false touch is low. The touch LCD screen 7 replaces the limitations of the original mechanical switch or traditional host computer software operation level and mechanical level, optimizes the user experience, and reduces the cost of personnel training and the possibility of false operation.

[0024] The rotating shaft 4 is horizontally distributed and one end is fixed on the inner wall of the housing 1 through a bearing seat 9, and the other end is protruded through the opening of the housing 1 and arranged outside the housing 1 to connect with the gate hoist. The center of the code disk 2 is vertically sleeved on the rotating shaft 4 in the housing 1 through a sleeve 5. During measurement, when the gate hoist is running, the internal motor works, that is, when the gate is lifted, the rotating shaft 4 rotates with the operation of the motor in the gate hoist, which will drive the code disk 2 to rotate. Before use, after setting the gear ratio by touching the LCD screen 7, the device can work normally.

[0025] The mainboard 6 is horizontally fixed on the housing 1 below the panel 3. An electromagnetic induction counting circuit, a power charging management integrated circuit, an RS485 / 4-20mA circuit and a LoRa / Internet of Things module are provided on the mainboard 6. The power charging management integrated circuit is connected to the touch LCD screen 7, a lithium battery, a power cord, an electromagnetic induction counting circuit, an RS485 / 4-20mA circuit and a LoRa / Internet of Things module to control the power supply of each module.

[0026] The mainboard 6 adopts an industrial-grade 32-bit processor and has embedded software programming burned inside to connect various components, execute instructions, issue instructions, store instructions, etc.

[0027] The main body of the electromagnetic induction counting circuit is the reed switch, which is also called a reed switch. It is a component that automatically switches on and off according to the surrounding magnetic field. The encoding disk 2 is arranged in a circular structure and 16 magnet cores 10 are evenly spaced around the side circumference, corresponding to the electromagnetic induction counting circuit up and down; when the encoding disk 2 rotates, the magnet cores 10 on the side circumference of the encoding disk 2 installed perpendicular to the bottom plate sweep under the reed switch in the electromagnetic induction counting circuit one by one, driving the reed switch to continuously change from a passage to an open circuit and then from an open circuit to a passage. In this way, the gate opening is reflected as the number of rotations of the encoding disk 2, and the magnet cores 10 on the encoding disk 2 are used as a counting method to continuously sweep the magnetic field of the clarinet to make it repeatedly conduct and disconnect the process, so that a switching quantity is generated from the signal waveform. The electromagnetic induction counting circuit also includes logic chips such as NAND gate chips, Schmitt triggers, inverters, latch triggers, analog switch chips, and synchronous decimal reversible counters, which process the switch quantities generated from the encoder disk 2 step by step until they are transmitted to the main board 6. The embedded software programming in the main board 6 processes the data, thus ultimately achieving the effect of converting the analog quantity of the gate opening into a digital quantity.

[0028] The lithium battery and the power cord are respectively arranged in the housing 1, and the power cord is connected to the lithium battery through the charging controller. The touch LCD screen 7, the lithium battery and the power cord are respectively connected to the main board 6. The antenna 8 is located on the back of the housing 1 on the protruding side of the rotating shaft 4 and is connected to the main board 6. During normal operation, it is connected to the mains through the power cord, and the mains supplies 12-36V DC power to the device and charges the lithium battery at the same time; if there is an unexpected situation such as a power outage, the lithium battery will supply power to the device to ensure that the data is not lost. The encoder disk 2 collects the gate opening value, and after being processed by the electromagnetic induction counting circuit and the main board 6, the gate opening value and parameter setting information are displayed on the touch LCD screen 7. The measurement resolution is 1cm. As long as the gate opening value changes, it will be immediately displayed on the touch LCD screen 7 through circuit processing.

[0029] This application supports two parameter configuration methods: on-site touch screen configuration and serial port configuration. The parameters that need to be configured include serial port communication address, baud rate, gear ratio of on-site gears and other information. On-site configuration uses the method of directly clicking on the touch screen, which is suitable for the initial installation of the equipment and subsequent inspections, maintenance and other scenarios; serial port configuration is to connect the communication cable to the computer through the RS485 data output interface and 4-20mA analog output interface set by the RS485 / 4-20mA circuit of the equipment, and configure it through the host computer software installed on the computer.

[0030] The wireless communication module adopts LoRa / IoT module, which is fixed on the main board 6 and connected with the main board 6 by circuit and embedded software programming, so that the device supports LoRa and NB-IoT wireless communication methods and can communicate wirelessly with RTU, server and other devices. The use of these two complementary wireless communication technologies can meet the communication needs of almost all user occasions.

[0031] In order to extend the communication distance, an antenna 8 made of a rubber stick material with a 3dB gain is placed outside the housing 1 to extend the signal transmission distance of the wireless communication module.

[0032] After testing, the communication distance can reach about 3 kilometers when using loRa module for transmission.

[0033] The main board 6 is also provided with a charging voltage monitoring circuit (not shown in the drawings), a battery voltage monitoring circuit (not shown in the drawings) and an external watchdog reset circuit (not shown in the drawings) and are respectively connected to the power charging management integrated circuit. The charging voltage monitoring circuit and the battery voltage monitoring circuit support voltage self-checking. The watchdog command has the highest priority in the program interruption. It can regularly check the internal situation of the chip and send a restart signal to the chip once an error occurs.

[0034] To sum up, the touch-type gate opening sensor pointed out in the utility model integrates functions such as data acquisition, wireless communication, data display, and touch parameter configuration. It adopts an integrated design and is programmed through internal circuit design and embedded software. It can work independently and stably by simply clicking on the screen to set the parameters. The device can automatically collect data in real time, display the data on the screen in real time, and automatically send it to the server, which improves the user experience, reduces the error rate and mechanical wear rate, and reduces personnel training costs. It greatly optimizes the application method of traditional sensors, breaks the limitations of the functions of traditional sensor devices, and has almost no maintenance costs except for the damage of parts.
