Detailed Description
In order to make the objects, technical solutions and advantages of the present disclosure more clear, the technical solutions of the present disclosure will be clearly and completely described below with reference to the specific embodiments and the accompanying drawings. It is to be understood that the embodiments described are only a few embodiments of the present disclosure, and not all embodiments. All other embodiments obtained by a person of ordinary skill in the art based on the embodiments in the present specification without any creative effort belong to the protection scope of the present specification.
As shown in fig. 1, an embodiment of the present invention provides an optical-electrical direct-reading meter, including:
the character wheel 10, the microprocessor 20, the communication module 30 and the photoelectric direct reading module 40; wherein the content of the first and second substances,
each hub of the character wheel 10 is provided with at least two photosensitive areas, the at least two photosensitive areas correspond to the photosensitive areas one to one, and the photosensitive areas on the same hub are different;
the photoelectric direct-reading module 40 is configured to collect photosensitive information of a current photosensitive area on each hub, which corresponds to the photoelectric direct-reading module 40 in position, determine current unit numbers respectively displayed on each hub according to each photosensitive information, generate flow data by using each determined current unit number, and send the flow data to the microprocessor 20;
the microprocessor 20 is configured to receive the flow data sent by the photoelectric direct reading module 40 and forward the flow data to the communication module 30;
the communication module 30 is configured to receive the flow data sent by the microprocessor 20 and forward the flow data to a remote management platform.
As shown in fig. 1, the meter includes a print wheel, a microprocessor, and a photo-electric direct reading module, where each hub of the print wheel is provided with at least two photosensitive areas, and the photo-electric direct reading module can collect photosensitive information of a current photosensitive area on each hub corresponding to the photo-electric direct reading module in position, and since a plurality of photosensitive areas on the same hub are different, that is, different photosensitive areas can correspond to different photosensitive information, and each photosensitive area corresponds to each unit number one to one, the photo-electric direct reading module can determine a current unit number respectively displayed by each hub of the print wheel according to the photosensitive information of each current photosensitive area, so as to generate flow data by using the current unit number respectively displayed by each hub, and the generated flow data is the same as flow data formed by the current unit numbers respectively displayed by each hub of the print wheel, and accordingly, when the generated flow data is sent to a remote management platform through the microprocessor and the communication module, the remote management platform can more accurately obtain an actual flow of a medium flowing through the meter.
For example, the print wheel of the photoelectric direct-reading meter includes 8 hubs A1, A2, A3, A4, A5, A6, A7, A8 in linear association, where 8 hubs correspond to ten thousand, hundred, ten, one, ten, percent, and thousandth of flow data in sequence, each hub is attached with 10 unit numbers of 0 to 9, and each hub is provided with a photosensitive area corresponding to each unit number one to one (the photosensitive areas corresponding to the same unit number on different hubs are the same), because photosensitive information of different photosensitive areas is different (for example, the intensity of feedback light formed by reflecting or transmitting the same light by different photosensitive areas is different, and the size of induction current formed by triggering the same photosensitive unit by feedback light formed by different photosensitive areas is different), after the photosensitive information of the current photosensitive area corresponding to the photoelectric direct-reading module on each hub is acquired, the current hub displayed current unit number data of each hub can be determined according to the photosensitive information of each current photosensitive area, for example, when the current hub generates 891, 8, and records the flow data according to the current unit numbers of 891, 893, 8, and 898, which correspond to the flow data.
It should be understood by those skilled in the art that the photoelectric direct-reading meter may further include other components such as a base meter or a screen display unit, and when a medium flows through the base meter, the base meter may reciprocate to drive a designated hub of the print wheel to rotate, so that each hub in the print wheel is linked to display a corresponding unit number, and finally, the actual flow rate of the medium flowing through the base meter is recorded and displayed through the print wheel.
As shown in fig. 1, the embodiment does not use the combination of the magnet, the magnetic induction element and the microprocessor to calculate the flow data in the conventional meter, so as to avoid the magnetic induction element being interfered by the external magnetic field or the stored flow data being lost to affect the accuracy of the calculated flow data, thereby avoiding the remote management platform or the screen display unit being unable to accurately know or display the actual flow of the medium flowing through the meter.
It should be noted that each photosensitive region on the same hub is different, and specifically, each photosensitive region on the same hub includes, but is not limited to, different shapes, different sizes, different reflective areas or different transmissive areas.
Referring to fig. 2, in an embodiment of the present invention, the optical-electrical direct-reading meter further includes: a power supply module 50; wherein, the first and the second end of the pipe are connected with each other,
the microprocessor 20 is configured to control the power module 50 to output a working current to the photoelectric direct reading module 40 under an external trigger; and when receiving the flow data sent by the photoelectric direct reading module 40, controlling the photoelectric direct reading module 40 to power down.
In this embodiment, the power module may generally be a storage battery, the microprocessor controls the power module to output a working current to the photoelectric direct-reading module only when receiving an external trigger, so that the photoelectric direct-reading module implements a corresponding service flow provided in the foregoing embodiment according to the working current output by the power module, and the microprocessor controls the photoelectric direct-reading module to power down when receiving flow data sent by the photoelectric direct-reading module, that is, the photoelectric direct-reading module is powered up only when a meter reading service needs to be implemented in the photoelectric direct-reading meter, which can reduce electric energy consumed by the photoelectric direct-reading module and improve a duration of the power module.
In order to specifically realize reduction of electric energy consumed by the photoelectric direct-reading module and improvement of the endurance time of the power module, the invention specifically provides two implementation modes, namely an implementation mode 1 and an implementation mode 2, of the photoelectric direct-reading meter.
Implementation mode 1: the photoelectric direct-reading meter further comprises: a clock module; the clock module is used for triggering the micro-processing periodically at set time intervals; and the microprocessor is used for controlling the power supply module to output working current to the photoelectric direct-reading module under the triggering of the clock module.
Implementation mode 2: the communication module is further used for receiving a data acquisition instruction sent by the remote management platform and forwarding the data acquisition instruction to the microprocessor; the microprocessor is used for controlling the power supply module to output working current to the photoelectric direct-reading module when receiving the data acquisition instruction forwarded by the communication module.
As will be understood by those skilled in the art, the controlling of the power down of the photoelectric direct reading module by the microprocessor specifically means that the microprocessor controls the power supply module to stop outputting the working current to the photoelectric direct reading module, so that the photoelectric module does not consume the electric energy stored in the power supply module any more.
Referring to fig. 3, in an embodiment of the present invention, the photoelectric direct reading module 40 includes: a photoelectric processing circuit 401, at least two groups of light emitting units 402 and light sensing units 403 which are in one-to-one correspondence with the hubs 101; wherein the content of the first and second substances,
each of the light emitting unit 402 and the light sensing unit 403 is connected to the photoelectric processing circuit 401;
the microprocessor 20 is configured to control the power module 50 to output a working current to the photoelectric processing circuit 401 under an external trigger;
each of the light emitting units 402 is configured to generate incident light according to the working current received by the photoelectric processing circuit 401, and the generated incident light can be irradiated to a specified position, so that the current photosensitive area 1011 on the hub 101 corresponding to the light emitting unit 402 at the specified position processes the incident light irradiated to the specified position to form feedback light;
each photosensitive unit 402 is configured to receive feedback light formed by the current photosensitive area on the hub corresponding to the photosensitive unit 402, form an induced current according to the received feedback light and the working current received by the photoelectric processing circuit 401, and output the formed induced current to the photoelectric processing circuit 401;
the photoelectric processing circuit 401 is configured to determine, according to the induced current respectively sent by each light sensing unit 402, a current unit number respectively shown by the hub 101 corresponding to each light sensing unit 402, generate flow data by using each determined current unit number, and send the flow data to the microprocessor 20.
In this embodiment, the photoelectric processing circuit may specifically use a circuit board as a carrier, and each of the light emitting units and the light sensing units may be mounted on the circuit board to be connected to the photoelectric processing circuit.
In this embodiment, the circuit board on which each light-emitting unit and each light-sensing unit are mounted should be fixed in the optical electrical direct-reading meter (for example, fixedly connected to the base meter or the corresponding housing), and each group of light-emitting unit and each group of light-sensing unit should be kept in correspondence with the corresponding hub in position (refer to fig. 4 and 5), so that when the photoelectric processing circuit receives the operating current output by the power module each time, the same light-emitting unit can generate incident light capable of irradiating the same designated position corresponding to the current light-emitting unit according to the operating current. Thus, for each light-emitting unit, when the current hub corresponding to the current light-emitting unit rotates to enable any one current photosensitive region arranged on the current hub to be located at a specified position, the current photosensitive region located at the specified position may process incident light irradiated to the specified position (for example, reflect or transmit part of the incident light irradiated to the specified position) to form feedback light; because the photosensitive areas on the same hub are different from each other, feedback lights (including but not limited to different feedback light intensities) formed by processing corresponding incident lights by the different photosensitive areas on the same hub are different from each other, when the current photosensitive unit corresponding to the current light-emitting unit receives the feedback lights (reflected light reflected by the current photosensitive area or transmitted light transmitted by the current photosensitive area) formed by the different photosensitive areas, induced currents corresponding to different current thresholds can be formed, the photoelectric processing circuit can determine the current unit number respectively shown by the hub corresponding to each photosensitive unit according to the induced currents respectively sent by the photosensitive units (i.e. the photosensitive information of the current photosensitive area located at a corresponding specified position on the hub corresponding to the current photosensitive unit), and thus, the determined current unit numbers are used for generating flow data.
When any one of the current photosensitive areas arranged on the hub reaches the designated position corresponding to the corresponding light-emitting unit due to the rotation of the hub, the current photosensitive area can specifically process incident light irradiated to the designated position by the corresponding light-emitting unit through a reflection mode or a perspective mode.
A: referring to fig. 4, when processing the incident light in the reflective mode, in one embodiment of the present invention,
the outer side wall of each hub 101 is uniformly attached with 10 unit numbers of 0-9 along the circumferential direction;
the photosensitive region includes: a light-reflecting film 60; wherein the content of the first and second substances,
for each unit number, the area adjacent to the unit number on the outer side wall of the hub 101 is provided with the reflective membrane 60 corresponding to the unit number;

When the incident light is processed by the reflective mode, the photosensitive region may be specifically the reflective membrane 60 disposed on the outer sidewall of the hub, and the corresponding set of the light emitting unit 402, the light sensing unit 403 and the corresponding hub 101 are in a positional relationship as shown in fig. 4, where the light emitting unit 402 and the light sensing unit 403 are both located outside the outer sidewall of the hub 101, when the hub 101 rotates around its axis to make a current reflective membrane 60 disposed on the hub 101 located at a specified position corresponding to the light emitting unit 402, a part of the incident light formed and irradiated to the specified position by the light emitting unit 402 may be reflected by the current reflective membrane 60 to the light sensing unit corresponding to the light emitting unit 402, and the rest part of the incident light may be absorbed or diffusely reflected by the hub 101 at the specified position 403.
Referring to fig. 4, specifically, for example, a reflective membrane 60 corresponding to the unit number 8 is disposed in an area adjacent to the unit number 8 on the outer sidewall of the hub 101, when the reflective membrane 60 corresponding to the unit number 8 is located at a specific position corresponding to one light-emitting unit 402, because the reflective membranes 60 corresponding to each unit number are different, when each reflective membrane reflects incident light, the intensity of the formed reflected light (or the shape and size of the photosensitive area corresponding to the reflected light irradiating the photosensitive unit) is different, correspondingly, when the reflective membranes corresponding to different unit numbers are located at the specific position corresponding to the photosensitive unit 402, the induced currents formed by the photosensitive unit 403 and output to the photoelectric processing circuit are different, and the photoelectric processing circuit can determine that the current unit number displayed by the hub 101 corresponding to the photosensitive unit 403 is 8 according to the induced currents sent by the photosensitive unit 403.
B: referring to fig. 5, when processing the incident light in the transmissive mode, in one embodiment of the present invention,

for each unit number, the transmission hole 1011 corresponding to the unit number is arranged on the hub 101, and a connecting line between the two corresponding unit numbers and the transmission hole 1011 penetrates through the center of the hub 101;
the group of light emitting units 402 and the group of light sensing units 403 corresponding to the hub 101 are respectively located at two sides of the hub 101, and the connecting lines between the group of light emitting units 402 and the group of light sensing units 403 corresponding to each other are parallel to the axis of the hub 101;
each of the light emitting units 402 is configured to generate incident light according to the operating current received by the photoelectric processing circuit 401, and the generated incident light can be irradiated to a specified position, so that the current transmission hole 1011 located at the specified position on the hub 101 corresponding to the light emitting unit 402 transmits the incident light irradiated to the specified position to form transmitted light;
each of the light sensing units 403 is configured to receive the transmitted light formed by the current transmission hole 1011 on the hub 101 corresponding to the light sensing unit 403, form an induced current according to the received transmitted light and the working current received by the photo processing circuit 401, and output the formed induced current to the photo processing circuit 401.
When the incident light is processed through the light transmission mode, the photosensitive area may specifically be a transmission hole 1011 disposed on the hub, and a set of the light emitting unit 402, the photosensitive unit 403 and the corresponding hub 1011 are located in a positional relationship as shown in fig. 5, where the light emitting unit 402 is located on a first side of the hub 101, and the photosensitive unit 403 is located on a second side of the hub 101, and when the hub 101 rotates so that one current transmission hole 1011 disposed on the hub 101 is located at a designated position corresponding to the light emitting unit 402, a part of the incident light formed by the light emitting unit 402 and irradiated to the designated position may be transmitted to the photosensitive unit 403 located on the other side of the hub 101 through the transmission hole 1011, and the rest of the incident light may be absorbed or diffusely reflected on the first side of the hub 101 at the designated position.
Referring to fig. 5, the transmission hole 1011 corresponding to the unit number 8 is disposed on the hub, and a connection line between the unit number 8 and the transmission hole 1011 corresponding to each other passes through a center of the hub 101, when the hub 101 displays the unit number 8, the transmission hole 1011 corresponding to the unit number 8 is located at a specific position corresponding to the light emitting unit 402, because the transmission holes 1011 corresponding to each unit number are different, when the transmission holes transmit incident light, intensities of the formed transmitted light (or shapes and sizes of photosensitive areas corresponding to the transmitted light irradiated to the photosensitive units) are different, and correspondingly, when the transmission holes corresponding to different unit numbers are located at the specific position corresponding to the photosensitive units 402, induced currents formed by the photosensitive units 403 and output to the photoelectric processing circuit are different, and the photoelectric processing circuit can determine the current unit number real 8 displayed by the hub 101 according to the induced currents formed and sent by the photosensitive units 403.
Because the formed feedback lights are completely the same when the same photosensitive areas process the same incident lights under ideal conditions, but there may be measurement errors or working condition errors in the actual service scene, in order to eliminate the measurement errors and the working condition errors, and ensure that the photoelectric processing circuit can accurately determine the current unit numbers respectively displayed by the hubs corresponding to each photosensitive unit according to the induced currents respectively formed and output by each photosensitive unit, please refer to fig. 6, in an embodiment of the present invention, the photoelectric direct reading module 40 further includes: a storage unit 404; the storage unit 404 is configured to store a current threshold corresponding to each unit number;

In this embodiment, the photosensitive units form and output induced currents according to the received feedback light, and depend on the intensity of the received feedback light, that is, depend on the shape, size, or photosensitive area of the current photosensitive region located at the corresponding designated position, so that when different photosensitive regions on the same hub are located at the corresponding designated positions, the induced currents formed and output by the corresponding photosensitive units can be located within different current thresholds; the photosensitive areas corresponding to the same unit numbers on different hubs may be the same, and the storage unit stores the current threshold corresponding to each unit number, that is, when the photosensitive area corresponding to each unit number is located at a corresponding designated position, the photosensitive area processes incident light irradiated to the corresponding designated position to form feedback light which is irradiated to the corresponding photosensitive unit, and then the photosensitive unit correspondingly forms a ratio variation range corresponding to induced current.
For the induced current formed and sent by each photosensitive unit, the photoelectric processing circuit firstly determines a current threshold corresponding to the induced current from the storage unit, and then determines the unit number corresponding to the determined current threshold as the current unit number displayed by the hub corresponding to the photosensitive unit.
In a possible implementation manner, each light emitting unit may be composed of a plurality of arrays of light emitting diodes and a light guide cover, and when the plurality of arrays of light emitting diodes generate incident light according to the photoelectric processing circuit, the corresponding light guide illumination may enable the incident light generated by each light emitting diode to form a regular light beam to irradiate on a designated position corresponding to the current light emitting unit.
In a possible implementation manner, each photosensitive unit may be composed of a plurality of arrays of photosensitive diodes, when the photosensitive unit receives feedback light formed by the photosensitive region located at the corresponding designated position, each photosensitive diode may be turned on under the action of the feedback light, and the magnitude of an induced current formed and output by turning on each photosensitive diode of the arrays depends on the intensity of the received feedback light, that is, depends on the shape, size, or photosensitive area of the current photosensitive region located at the corresponding designated position.
