Description

Transmitter and method of operating a transmitter

Technical Field

The present disclosure relates generally to signal measurements, and in particular, to transmitters and methods of operating transmitters.

Background

A transducer is a transducer that converts an output signal from a sensor into a signal that can be recognized by a controller.

For example, flow meters for measuring fluid flow may include measurement tubes, drivers, sensors, and transmitters. Illustratively, such a transmitter includes three modules within it: the device comprises a display module, a functional module and a core processing module. The three modules are physical modules and have physical structures and connection relations. The core processing module sends out a driving signal for driving the driver; the core processing module also receives analog signals generated by the sensor in response to the movement of the driver; the core processing module converts the analog signal into a digital signal and provides the digital signal to the functional module. The core processing module is connected with the functional module through a four-wire cable. The functional module comprises a digital signal processing unit. The digital signal processing unit processes the received digital signal and provides a display signal to the display module. The display module includes a liquid crystal display unit. The liquid crystal display unit displays information, such as a current flow rate, to a user based on the display signal. For example, for an existing 1600 transmitter, the display module includes a connector J101, the function module includes a circuit board on which a processor chip is mounted, the 14 pin connector J101 serves as a communication interface between the display module and the function module for transmitting SPI (Serial Peripheral Interface) signals, and a 4-wire connection cable for supplying power and transmitting RS485 signals is provided between the core processing module and the function module.

Exemplary embodiments of the present disclosure will be described hereinafter with reference to the accompanying drawings. In the interest of clarity and conciseness, not all features of an actual implementation are described in this specification. It will be appreciated, however, that in the development of any such actual embodiment, numerous implementation-specific decisions may be made to achieve the developers' specific goals, and that these decisions may vary from one implementation to another.

One aspect of the present disclosure discloses a transmitter. The transmitter is described in an exemplary manner with reference to FIG. 1.

FIG. 1 illustrates a block diagram of a structure of a transmitter 10 in accordance with one embodiment of the present disclosure. By way of example, transmitter 10 may be used with a variety of measurement devices such as a flow meter. Transmitter 10 includes: a housing (not shown); and a display module 11, a core processing module 13, and a functional module 15 disposed inside the housing. The core processing module 13 includes a driving unit 131 and an analog-to-digital conversion unit 133. The functional module 15 includes a digital signal processing unit 151. The function module 15 is configured to wirelessly supply power required for operation to the display module 11 and the core processing module 13. The function module 15 supplies power to the display module 11 and the core processing module 13 based on input power Pin received from the outside (e.g., an external power supply). That is, the power supply mode of the functional module to the display module is not a wired mode but a wireless mode; the manner in which the functional module supplies power to the core processing module is not a wired manner but a wireless manner. The drive unit 131 is configured to generate a drive signal Sdr for driving a driver, wherein the driver is located outside the transducer, the driver moving under the control of the drive signal Sdr. The core processing module 13 receives an analog signal Sin generated by the sensor in response to the movement of the driver. The analog-to-digital conversion unit 133 is used for converting the analog signal Sin into a digital signal Sdi for processing by a digital signal processor. The display module 11 includes a display screen (not shown) to display various information to the user. Information includes, but is not limited to: and measuring the result. The display screen is, for example, a liquid crystal screen or an LED display screen. Optionally, the display module 11 may further include an indicator light (e.g., LED indicator light), (touch) button, and the like. The digital signal processing unit 151 determines the flow rate, for example, based on the digital signal Sdi received from the core processing module 13. Optionally, the functional module 15 further comprises a power supply unit 153 and/or an output interface 155. The power supply unit 153 may be used to convert the input power Pin into matching power that can be used by the electronic modules within the functional module 15, for example, into power that can be used by the digital signal processing unit 151. The output interface 155 is used to export the output result of the digital signal processing unit 151 to other devices including external devices, not the display module 11. Compared with the function module which supplies power to the display module and the core processing module through hard connection lines, the hard connection lines can be omitted when power is transmitted in a wireless mode, equipment assembly becomes flexible and simple, and disassembly is easier.

In one example, the functional modules are arranged between the display module and the core processing module, i.e. three modules are arranged in one direction, wherein the functional modules are arranged in an intermediate position.

In one example, transmitter 10 can be implemented with a wireless power transceiver. A wireless power delivery implementation of the transmitter of the present disclosure is illustrated below with reference to fig. 2.

FIG. 2 shows a block diagram of the structure of transmitter 20 in accordance with another embodiment of the present disclosure. Transmitter 20 includes: a housing (not shown); and a display module 21, a core processing module 23, and a functional module 25 disposed inside the housing. The core processing module 23 includes a driving unit 131 and an analog-to-digital conversion unit 133. The functional module 25 includes a digital signal processing unit 151. The function module 25 is configured to wirelessly supply power required for operation to the display module 21 and the core processing module 23. The function module 25 supplies power to the display module 21 and the core processing module 23 based on input power Pin received from the outside (e.g., an external power supply). The core processing module 23 receives an analog signal Sin generated by the sensor in response to the movement of the driver. The display module 21 includes a display screen to display various information to the user. Information includes, but is not limited to: and measuring the result. The display screen is, for example, a liquid crystal screen or an LED display screen. Optionally, the display module 21 may further include an indicator light, a button, and the like. The digital signal processing unit 151 determines the flow rate, for example, based on the digital signal Sdi received from the core processing module 23. Optionally, the functional module 25 further comprises a power supply unit 153 and/or an output interface 155. The transmitter 20 includes the same elements as those of FIG. 1 for function as those elements having the same reference numerals as previously described with respect to FIG. 1. In contrast to transmitter 10 in FIG. 1: display module 21 of transmitter 20 includes a first wireless power receiver 211; functional module 25 of transmitter 20 includes a first wireless power transmitter 257, a second wireless power transmitter 259; core processing module 23 of transmitter 20 includes a second wireless power receiver 235. The first wireless power receiver 211 is for receiving power from the first wireless power transmitter 257. The second wireless power receiver 235 is for receiving power from the second wireless power transmitter 259. Such a configuration is advantageous in achieving distribution of power matching the power consumption specifications of the display module and the core processing module. For example, when the specification of the power required for the display screen of the display module 21 is Direct Current (DC) 3.3V; when the power required by the analog-to-digital conversion unit 133 and the driving unit 131 of the core processing module 23 has a specification of Direct Current (DC) 15V, the first wireless power receiver 211 may be configured to output 3.3V DC power, and the second wireless power receiver 235 may be configured to output 15V DC power.

The Qi standard is a 'wireless charging' standard which is pushed out by the standardization organization of the wireless charging technology, namely wireless charging alliance (Wireless Power Consortium, WPC), and has two main characteristics of convenience and universality. Different brands of products, as long as there is one identification of Qi, can be charged with Qi wireless chargers. In order to improve versatility of the product, convenience of maintenance, the first wireless power transmitter 257 and the second wireless power transmitter 259 include wireless power transmitters conforming to Qi standard; and the first wireless power receiver 211 and the second wireless power receiver 235 include wireless power receivers conforming to the Qi standard.

In one example, the first wireless power transmitter 257 is a TB6865FG transmitter; the second wireless power transmitter 299 is an STWBC2-HP transmitter; the first wireless power receiver 211 is a TB6860WBG receiver manufactured by TOSHIBA (TOSHIBA); the second wireless power receiver 235 is an STWLC68 receiver. TB6865FG transmitter is mounted on a circuit board in the functional module 25. The TB6860WBG receiver is utilized to provide the 3.3V dc power required for display while the maximum current of power it provides also meets the display module requirements. The STWLC68 receiver can be programmed to provide 15V of direct current to meet the requirements of the analog to digital conversion unit and the drive unit. The TB6860WBG receiver is capable of meeting the needs of the display panel in the display module in terms of size, output voltage, maximum output current.

A top layer of Indium Tin Oxide (ITO) 305, a glass spacer 307, a bottom layer of indium tin oxide 309 as a touch detection stack (i.e., a touch sensing unit) for touch detection. The liquid crystal display unit is a liquid crystal panel. That is, the display module of the transmitter with the integrated structure 30 does not require a dedicated cover glass, but rather the glass cover of the housing serves as a cover glass for protecting the liquid crystal panel. That is, the display module of the transmitter with integrated structure 30 does not include cover glass. The adoption of the integrated structure is beneficial to reducing components, fully utilizes the space in the shell, has a more compact structure, saves the internal space of the shell and reduces the cost of devices. Meanwhile, after the integrated structure is adopted, the cover plate glass is omitted, so that the distance between the touch detection lamination and the glass cover plate of the shell is reduced, and the touch detection is more sensitive.
