Description

Control system based on fluid sensor and wireless power transmission method thereof

The present invention relates to the field of sensors and artificial intelligence; more specifically, it particularly relates to a control system based on a fluid sensor and a wireless power transmission method thereof.

The Internet of Things technology has been widely used in the field of sensor technology, enabling sensors to communicate with each other and operate in association with each other, and even send sensor data to a wireless network device that can connect to the Internet. The Internet sends reports to cloud server devices or mobile devices to achieve remote alarm purposes. The user can also use the cloud server device or mobile device network to connect to the wireless network device, so as to send control commands to the corresponding sensor to remotely control the operation of the specific sensor.

The design of the current sensor's sensing and notification method can be divided into two categories, one is that only has wireless communication function, can only transmit through Bluetooth, low-speed and short-distance wireless network communication protocol, frequency modulation or infrared. Wireless communication technology for communication, the other is both wireless communication function and wireless network function, can be set to communicate with other sensors through wireless communication technology, or through the Internet for data transmission. Therefore, when setting up a sensor system, a sensor with both wireless communication and wireless network functions is usually used to receive the sensing data of a sensor with only wireless communication function, and to connect to wireless network equipment. Send the sensing data to the cloud server device or the mobile device.

Today, many sensor electrodes are used to measure fluid parameters, such as pH, total solution Solving solids and oxidation-reduction potential, etc., adopt galvanic isolation to prevent stray current from water or high-humidity air from interfering with other sensor electrodes, pumps, heaters, etc. These stray currents may interfere with electrodes or other sensors. The measuring device of the detector may cause the output value to shift or fluctuate, thereby causing measurement and control errors. This usually means that pen-type sensors use batteries as a method of galvanic isolation, while AC-powered sensor electrode instruments use an independent isolated power supply that provides galvanic isolation, or instruments with multiple sensor electrodes usually use electrical Multiple DC-DC converters with isolated primary and multiple galvanic isolation. The secondary side provides power for each sensor electrode. In addition, most existing pen-type sensors do not transmit their measured output to the control system, while single or multiple electrode sensor systems mostly use cables and connectors to connect to the control or monitoring system, where these wires and Connectors are often corroded or cracked, and many of them have buffered signals in the combined sensor cable, making them susceptible to electromagnetic interference and changes in cable/connector impedance. Although the existing wireless power supply and wireless communication sensor system does not use radio frequency identification (Radio Frequency IDentification, referred to as: RFID), near-field communication (abbreviated as: NFC) or batteries with self-powered technology, these It may not be possible to provide sufficient power and stability for the combination of the sensor technology of the present invention, which is related to galvanic isolation and communication. In a typical application of the present invention, the processing requirements, reliability and ease of use of the fluid sensor element received by the processing unit will be utilized. Although other wireless power supply and wireless communication sensor systems use multiple sensor systems, these sensor systems may not be able to provide separate galvanic isolation for each sensor and/or have a more complex system structure, so they have obvious More potential failure points, especially when the system includes more wired and/or wireless communication interfaces, where any loss of communication between these interfaces will cause serious system failures, and the sensor components have a pair of broken Sensitive cables, interference and corrodible connectors that may be difficult to separate, and may produce poor electrical connections. And when a wireless control system is required to use multiple liquid sensors, the existing type usually requires multiple discrete components, such as power adapters, batteries, and processing/communication modules to sense them The sensor signals are transmitted to a central data collection, monitoring and/or control. Although most multiple sensor electrode systems using a single power supply have multiple DC-DC converter modules for each sensor electrode parameter. This makes all these solutions relatively expensive and more complicated to install and operate with respect to the end user, while at the same time prone to a higher degree of failure compared to the present invention.

Therefore, the main purpose of the present invention is to provide a fluid sensor-based control system and its wireless power transmission method, and in order to overcome the shortcomings of the above-mentioned more traditional and more complex system architecture methods, while allowing other sensors Measurement technology is used in more robust and information-rich control, and is simply upgraded or serviced by the end user.

Electricity is transmitted through the processing unit and the housing of the fluid sensor element in a manner similar to the wireless mobile phone charging system. However, the system of the present invention is different from the system usually used for the mobile phone wireless charging system. Each fluid sensor element Requires less electricity, and there is no battery to charge or replace. Each fluid sensor can be supplied with electricity long enough to provide stable sensor measurements when needed. Therefore, the fluid sensor element only operates when it is received by the processing unit or the adapter module. Since the sensor electrode module is wireless, the optical signal transmission method is used to transmit the measured sensor signal from the sensor electrode module to the processing unit, because the optical method passes through the fluid sensor element and the processing unit housing It is a short distance, so it is not easily affected. Compared with the communication protocols usually used in other wireless systems, it interferes and requires very little processing. In this system, the receiving frequency of the measured sensor is sampled by the hardware counter timer, which reduces the required processing power. The adapter module can use the same power and sensor signal transmission method to further facilitate the placement of the remote sensor electrode module, allowing the sensor to be placed remotely or to facilitate the calibration process. The processing unit containing multiple fluid sensor elements is slightly above the liquid to be measured, and any fluid sensor element will be the sensor element. The piece protrudes down into the liquid, and the parameters of the liquid will be measured. Both the processing unit and the fluid sensor element can be easily manufactured as a wireless waterproof and anti-corrosion unit.
