The following description of the embodiments is merely intended to provide a better understanding of the present invention by illustrating examples of the present invention.
It is noted that, herein, relational terms such as first and second, and the like may be used solely to distinguish one entity or action from another entity or action without necessarily requiring or implying any actual such relationship or order between such entities or actions. Also, the terms "comprises," "comprising," or any other variation thereof, are intended to cover a non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements does not include only those elements but may include other elements not expressly listed or inherent to such process, method, article, or apparatus.

The nozzles in a printer are typically connected independently of other printing components in the printer via power lines to nozzle sockets. In the printing process of the printer, printing failure caused by that other parts of the printer are well electrified and a spray head of the printer is not successfully connected with a spray head socket often occurs. When the spray head is not normally electrified, the spray head cannot be normally used, and the spray head cannot discharge ink in the printing process. When a user finds that the nozzle does not discharge ink, the user can find that the nozzle is not electrified to cause printing failure after checking each part in the printer one by one. In the prior art, the detection method for the non-electrification of the spray head is complex, and the detection process is time-consuming and labor-consuming.
The invention provides a device, a method, equipment and a medium for detecting electrification of a nozzle control plate, which can solve the technical problem that the process for detecting whether the nozzle control plate is electrified is complicated and complicated in the prior art to a certain extent.
An embodiment of the present invention provides an electrical detection apparatus on a head control board, as shown in fig. 1, the apparatus includes a detection module 11, a head control board 12, a head power supply 13, and head electronics 120.
The head control board 12 is disposed inside the head, and includes a PCB and various head electronic parts 120 disposed on the PCB. Each of the head electronic components 120 is an electronic component. After the showerhead control board 12 is normally powered up, each showerhead electronics 120 will be able to function properly.
A detection module 11 for acquiring information from at least one head electronic part 120 provided on the head control board 12 and powered by the head power supply 13 after the head control board 12 is connected to the head power supply 13; and judges whether the head control board 12 is powered on or not according to the information acquisition result.
When the head control board 12 is connected to the head power supply 13, the head power supply 13 supplies power to the head electronic parts 120 on the head control board 12 to activate the head electronic parts 120.
After each of the showerhead electronic components 120 is powered on, it can operate normally and interact with other showerhead electronic components 120. The detection module 11 can determine whether the head control board 12 is normally connected to the head power supply 13 and whether the head control board 12 is powered on and can be normally used by acquiring information from at least one head electronic part 120 and according to the information acquisition result for each head electronic part 120. If the head electronic components 120 are normally powered on, the detection module 11 obtains a normal result of information about each head electronic component 120. If the head electronic parts 120 are not normally powered on, the result of acquiring information of each head electronic part 120 by the detection module 11 is not normal. The information acquisition result includes: whether the relevant information can be normally acquired from the head electronic part 120 or whether the information acquired from the head electronic part 120 is normal.
The head electronic part 120 includes a head memory 121, a temperature sensor 122, and a driving chip 123.
Fig. 2 is an internal circuit diagram of the detection module 11, two pins inside the first wire frame 200 are used for connecting the head memory 121, and the detection module 11 reads data stored in the head memory 121 through the integrated circuit bus I2C bus protocol, thereby acquiring head internal information (information of head generation date, head reference voltage, and the like). After the nozzle control board 12 is powered on, N pieces of data are acquired from the nozzle memory 121, and the software considers that the first state is normal. If any of the information acquisition signals sent from the detection module 11 to the head memory 121 is not answered, the information acquisition result is considered to be a failure.
Pins in the second wire frame 100 are used to connect the temperature sensor 122. After the detection module 11 acquires the temperature signal from the temperature sensor 122, it performs digital-to-analog conversion on the acquired temperature signal, and finally converts the temperature signal into a temperature value. If the temperature value obtained by conversion is greater than 0 ℃ and less than 60 ℃, the temperature information obtaining result is considered to be normal, otherwise, the temperature information obtaining result is judged to be abnormal, and the spray head control plate 12 is not electrified.
The pin in the third wire frame 300 is used to connect the driving chip 123, and the pin outputs a high level by default, and when the nozzle control board 12 is not connected to the nozzle power supply, is not connected, or the nozzle control board 12 is not powered on, the output level is a low level. Therefore, when the detection module 11 detects that the pin is at a high level, the third state is considered to be normal, otherwise, the third state is considered to be abnormal.
In one embodiment, fig. 3 is a flowchart of an application for detecting whether the head control board 12 is powered on by using the components shown in fig. 2.
As shown in fig. 3, after the printer is powered on, the detection module 11 for detecting whether the head control board 12 is powered on acquires information of at least two head electronic parts 120 provided on the head control board 12, and determines whether the head control board 12 is powered on according to the information acquisition result for each head electronic part 120. If the detection module judges that the nozzle control plate 12 is electrified, the printer works normally to perform printing operation. And if the detection module 11 judges that the spray head control plate 12 is not electrified, generating prompt information. After seeing the prompt message, the user will turn off the printer, and investigate the reason why the head control board 12 is not powered on. And restarting the printer after the completion of the investigation.
In one embodiment, as shown in FIG. 5, the showerhead electronics 120 includes a showerhead memory 121. The information acquisition result includes: the information on the heads can be normally acquired from the head memory 121, and the information on the heads cannot be normally acquired from the head memory 121.
The head memory 121 is disposed inside the head, electrically connected to the head power supply, and stores information related to the head.
In one or more embodiments of the invention, the head Memory 121 includes an EEPROM (Electrically-Erasable Programmable Read-Only-Memory). The EEPROM comprises an EEPROM with the model M24C 32-D.
If the detection module 11 can normally acquire information about the nozzles from the nozzle memory 121, the nozzle memory 121 is successfully powered on.
The information about the ejection head includes: the production date of the nozzle, the type of the nozzle, printing information required by the nozzle printing, the reference printing of the nozzle and the like.
The detection module 11 is connected to the nozzle storage 121, and is configured to acquire information related to the nozzle from the nozzle storage 121, and determine whether the nozzle control board 12 is powered on according to whether the information related to the nozzle can be normally acquired from the nozzle storage 121.
The head memory 121 is provided on a circuit board inside the head. The circuit board inside the head is used to mount the electronic components in the head. When the head power supply 13 supplies power to the circuit board of the head, the circuit between the head memory 121 and the head power supply 13 is in a conducting state.
In one embodiment, the detection module 11 sends a plurality of information acquisition signals to the head memory 121 after the head memory 121 is powered on, and if the head memory 121 does not respond to any detection signal, the detection module 11 determines that the head control board 12 is not powered on.
Fig. 6 is a timing signal diagram of the detection module 11 shown in fig. 2, which is connected to the head memory 121, and detects the head memory 121. As shown in fig. 6, signals shown by the fourth, fifth, sixth, and seventh wire frames 400, 500, 700, and 800 are response signals of the head memory 121. The signal in the eighth line box 600 indicates that the head memory 121 is not responding.
When the head memory 121 is normal, and after the circuit between the head memory 121 and the head power supply 13 is in a conducting state, the head memory 121 can operate normally, and provides the print information required for printing to the head control board 12. During printing, the processor of the head control board 12 acquires the print information from the head memory 121 and performs printing using the print information.
The detection module 11 can determine whether the head memory 121 can be used normally according to whether the relevant information of the head can be normally acquired from the head memory 121, so as to determine whether the head control board 12 is powered on.
When the head control board 12 is powered on, the detection module 11 can normally acquire the information about the head control board 12 from the head memory 121. When the head is not powered on, the detection module 11 cannot normally acquire the information related to the head control board 12 from the head memory 121.
The detection module 11 can obtain the relevant information of the head control board 12 from the head memory 121, and includes: the detection module 11 acquires print information necessary for head printing from the head memory 121. During printing, the printer performs printing using the print information acquired from the head memory 121. After the head control board 12 is started, whether the head memory 121 can be normally used can be determined by whether printing information required for printing can be normally acquired from the head memory 121, so that whether the head control board 12 is powered on can be determined.
In one embodiment, as shown in FIG. 6, the showerhead electronics 120 includes a temperature sensor 122, and the information acquisition results include: the temperature sensor 122 is electrically connected to the head power supply 13 to determine whether the temperature signal obtained from the temperature sensor 122 is normal. The temperature sensor 122 is installed inside the head and used for detecting the temperature of the head control board 12 and generating a temperature signal according to the detection result.
In one embodiment, the temperature sensor 122 comprises a thermistor. The resistance value of the thermistor changes with the change of temperature. When the head control board 12 is energized, heat is generated by energizing the electronic components in the head control board 12, and the temperature of the head control board 12 rises. When the temperature of the head control plate 12 changes, the current value passing through the thermistor also changes, and this current value can be used as a temperature signal.
The temperature sensor 122 is provided on the head control board 12 for detecting the temperature of the head control board 12.
The detection module 11 is configured to determine whether the nozzle control board 12 is powered on according to whether the temperature signal obtained from the temperature sensor 122 is normal.
When showerhead control plate 12 is powered on, temperature sensor 122 is also powered on. The detection module 11 will acquire a temperature signal from the temperature sensor 122. The detection module 11 can convert the acquired temperature signal into a temperature value, and then judges whether the nozzle control plate 12 is electrified or not by judging whether the temperature value is within a normal temperature range of the nozzle control plate 12 or not. The normal temperature range of the spray head control plate 12 is between 0 and 60 degrees when the spray head works.
When the head control board 12 is powered on, each head electronic part 120 on the head control board 12 generates heat, which raises the temperature of the head control board 12. When the detection module 11 determines that the temperature of the nozzle control plate 12 is normal according to the temperature signal acquired by the temperature sensor 122, it can be determined that the nozzle control plate 12 is powered on.
In one embodiment, the temperature signal comprises an electrical signal within a set range of values. After the detection module 11 obtains the temperature signal, the temperature signal is used to calculate and obtain a temperature value. If the value of the temperature signal is too high or too low, the calculated temperature value is not in the normal temperature range. If the temperature value calculated and obtained by the detection module 11 is not within the normal range, it may be determined that the detection module 11 does not normally obtain the temperature signal, and it may be further determined that the temperature sensor 122 is not normally powered on. If temperature sensor 122 is not properly powered up, showerhead control board 12 may not be powered up.
After the temperature sensor 122 is powered on, the detection module 11 can receive a temperature signal from the temperature sensor 122, and further obtain the temperature inside the head control board 12 according to the temperature signal. When the temperature sensor 122 is not powered on, the detection module 11 cannot receive a temperature signal from the temperature sensor 122 or cannot receive a normal temperature signal.
In one embodiment, as shown in fig. 7, the head electronic part 120 includes a driving chip 123, and the information acquisition result includes: whether the electric signal obtained from the driving chip 123 is normal.
The driving chip 123 is electrically connected to the head power supply 13, and is configured to drive the electronic components on the head control board 12.
When the head is powered on, the driving chip 123 is in a conducting state with the head power supply 13. By detecting the driving chip 123, it can be determined whether the head control board 12 is powered on.
The driving chip 123 is electrically connected to the detection module 11 through a pin. The driving chip 123 outputs a current or a voltage to the detection module 11 after being powered on. When the driving chip 123 is not energized, no current or voltage is output to the detection module 11. The current or voltage output from the driving chip 123 to the detection module 11 is an electrical signal output from the driving chip 123 to the detection module 11.
The detection module 11 is configured to determine whether the nozzle control board 12 is powered on according to whether the electrical signal obtained from the driving chip 123 is normal.
In one embodiment, when the connection between the head control board 12 and the head power supply 13 is successful, the driving chip 123 sends a high-level electrical signal to the detection module 11. When the detection module 11 detects that the signal received from the driving chip 123 is a high level signal, the detection module 11 determines that the driving chip 123 is powered on successfully, otherwise, the detection module 11 determines that the driving chip 123 is powered on unsuccessfully.
For example, the electric signal obtained by the detection module 11 from the driving chip 123 is a current signal higher than a first set value or a voltage signal higher than a second set value.
If the current value or the voltage value received by the detection module 11 is low, the current value or the voltage value received by the detection module 11 may be noise.
The detection module 11 can determine whether the driving chip 123 is powered on according to whether the electrical signal acquired from the driving chip 123 is normal; whether the head control board 12 is powered up can be determined according to whether the driving chip 123 is powered up.
In one embodiment, the driving chip 123 is preset with data information for interacting with the detection module 11; the information acquisition result includes: whether the preset data information can be normally acquired from the driving chip 123.
The detecting module 11 is further configured to determine whether the nozzle control board 12 is powered on according to whether the data information can be normally acquired from the driving chip 123.
By presetting data information for interacting with the detection module 11 in the driving chip 123, the detection module 11 obtains the preset data information from the driving chip 123 after the driving chip 123 is started. The detection module 11 determines whether the driving chip 123 is powered on according to whether preset data information can be normally acquired from the driving chip 123, and further determines whether the head control board 12 is powered on according to whether the driving chip 123 is powered on.
The driver chip 123 and the detection module 11 CAN communicate with each other through UART (Universal Asynchronous Receiver/Transmitter), IIC (Inter-integrated circuit), SPI (Serial Peripheral Interface), CAN (Controller Area Network), USB (Universal Serial Bus), portal, FSMC (Flexible Static Memory Controller, variable Static Memory Controller) and other communication methods.
In one embodiment, as shown in FIG. 8, the device further includes a display device 14.
The detection module 11 is further configured to generate display information according to a determination result of determining whether the nozzle control board 12 is powered on, and send the display information to the display device 14.
The display information includes: when the nozzle control plate 12 is electrified, prompting the nozzle control plate 12 to display information of the electrified state; when the nozzle control board 12 is not powered on, the display information that the nozzle control board 12 is not powered on is prompted.
If the determination result obtained by the detection module 11 is that the head control board 12 is powered on, the detection module 11 generates display information when the head control board 12 is powered on. If the determination result obtained by the detection module 11 is that the head control board 12 is not powered on, the detection module 11 generates display information when the head control board 12 is not powered on.
And the display device 14 is used for displaying the received display information.
When the head control board 12 is powered on, the display device 14 receives display information when the head control board 12 is powered on. When the display device 14 receives the display information when the head control board 12 is powered on, it will display the prompt information such as "the head is powered on" to prompt the user that the head control board 12 can be used normally.
When the nozzle is not powered on, the display device 14 receives the display information when the nozzle control board 12 is not powered on. When the display device 14 receives the display information when the head control board 12 is not powered on, it will display the prompt information such as "failed start of the head", etc. to prompt the user that the head control board 12 cannot be used normally.

Step S1: acquiring information from at least one showerhead electronic component disposed on a showerhead control plate and powered by a showerhead power supply; step S2: and judging whether the spray head control plate is electrified or not according to the information acquisition result.
After the sprayer is normally connected with the sprayer power supply, the sprayer power supply can supply power to the sprayer electronic components for forming the sprayer so as to drive the sprayer electronic components to normally use. The head electronic parts are functional parts of the head and constitute the head. The showerhead electronics are powered by a showerhead power supply. In the printing process, each spray head electronic component can perform information interaction with other spray heads so as to perform printing. After each electronic nozzle component in the nozzle is electrified, the information acquisition result of each electronic nozzle component can be normal.
Whether the nozzle control board is electrified or not can be judged according to whether the information acquisition result of the nozzle electronic parts to each nozzle electronic part is normal or not. And if the information acquisition result of each nozzle electronic component is normal, judging that the nozzle control board is electrified. And if the information acquisition result of the electronic parts of the spray heads to the electronic parts of the spray heads is abnormal, judging that the control board of the spray heads is not electrified.
In one embodiment, the showerhead electronics includes a showerhead memory, the information acquisition result includes: whether the information related to the ejection head can be normally acquired from the ejection head memory.

And the spray head power supply is used for supplying power to all electronic components of the spray head.
The sprayer memory is arranged in the sprayer and electrically connected with the sprayer power supply and used for storing relevant information of the sprayer.
Information about the sprinkler, including: the type of the nozzle, the production date of the nozzle, printing information required by the nozzle printing, the reference voltage of the nozzle and the like. When the sprayer memory is normal, after the sprayer starts, the processor in the sprayer can normally acquire the printing information required by printing from the sprayer memory and print by utilizing the printing information, so that whether the sprayer memory is electrified or not is related to whether the sprayer can normally print or not, when the sprayer control panel is judged to be electrified or not, whether the sprayer memory is electrified or not needs to be judged, and only the sprayer memory is normal, the sprayer can normally print.
After the sprayer memory is electrified, the relevant information of the sprayer can be obtained from the sprayer memory. If the sprayer memory is not electrified, the relevant information of the sprayer cannot be acquired from the sprayer memory. Therefore, whether the nozzle storage is electrified or not can be judged according to whether the relevant information of the nozzle is acquired from the nozzle storage or not. Whether the nozzle control board is electrified or not can be judged according to whether the nozzle storage is electrified or not.
In one embodiment, step S1, obtaining information about the showerhead from a showerhead memory electrically connected to the showerhead power supply includes: after the nozzle control board is electrified, a plurality of information acquisition signals are sent to a nozzle memory; step S2, determining whether the nozzle control board is powered up according to whether the information can be normally acquired from the nozzle storage, includes: and if any one of the plurality of information acquisition signals does not respond to the information acquisition information, judging that the information cannot be normally acquired from the spray head memory, and not electrifying the spray head control plate.

The temperature sensor is used for detecting the temperature of the spray head control plate. When the nozzle control board is electrified, electronic parts of each nozzle on the nozzle control board generate heat, so that the temperature of the nozzle control board is increased. When the temperature of the spray head control plate is judged to be normal according to the temperature signal acquired by the temperature sensor, the fact that the spray head control plate is electrified can be determined.
In one embodiment, the temperature sensor is a thermistor. The thermistor is a resistor whose resistance value changes with the change of the external temperature. The temperature signal transmitted by the thermistor to the detector comprises: the value of the current through the thermistor. The resistance value of the thermistor changes with the outside temperature, and the current value passing through the thermistor also changes. The detection module can obtain the temperature of the position where the thermistor is located by carrying out data conversion on the received current value.
The temperature signal comprises an electrical signal within a set range of values. After the detection module acquires the temperature signal, the temperature signal is used for calculating and acquiring a temperature value. If the value of the temperature signal is too high or too low, the calculated temperature value is not in the normal temperature range. If the temperature value calculated and obtained by the detection module is not in the normal range, the detection module can be judged not to normally obtain the temperature signal, and the temperature sensor can be judged not to be normally powered on. If the temperature sensor is not normally powered on, the nozzle control board may not be powered on.
After the spray head is started, all electronic devices inside the spray head can operate after being electrified, and heat is continuously generated in the operation process. Therefore, the temperature value inside the nozzle, which is obtained by the detection module according to the received temperature signal, is continuously increased and then is within a numerical range. The detection module can further judge whether the spray head control board can be normally used according to the temperature value obtained by the received temperature signal. If the temperature value that detection module obtained according to temperature signal is in setting for the temperature range, then detection module judges that the shower nozzle control panel can normal use. If the temperature value obtained by the detection module according to the temperature signal is not within the set temperature range, the detection module judges that the spray head control plate can not be normally used. Setting the temperature range between 0 and 60 degrees, wherein the temperature inside the spray head is higher than 60 degrees, and spray head electronic components inside the spray head can be burnt out; the showerhead internal temperature is below 0o and the showerhead control plate may not be powered up.

The driving chip is electrically connected with the detection module through pins. The driving chip outputs current or voltage to the detection module after being electrified. If the driving chip does not output current or voltage to the detection module, or the output current or power is low, the detection module can judge that the driving chip is not electrified, and further judge that the nozzle control panel comprising the driving chip is not electrified.
The detection module judges whether the nozzle control panel is electrified or not according to whether the electric signal can be normally acquired from the driving chip or not.
The electric signal acquired by the detection module from the driving chip is a current signal higher than a first set value or a voltage signal higher than a second set value.
If the current value or the voltage value received by the detection module is low, the current value or the voltage value received by the detection module may be noise.
The detection module can judge whether the driving chip is electrified or not according to whether the electric signal is received or not; according to whether the driving chip is electrified or not, whether the nozzle control board is electrified or not can be judged.
In one embodiment, the information obtaining result includes: the preset data information can be normally acquired from the driving chip.
Step S1 further includes: acquiring preset data information from the driving chip; step S2 further includes: and judging whether the nozzle control board is electrified or not according to preset data information which can be normally acquired from the driving chip.

The showerhead control plate may have a plurality of showerhead electronics for supporting the normal operation of the showerhead. Only after each electronic part of the spray head is electrified normally, the spray head can work normally. Therefore, before the head starts to operate, it is necessary to acquire information from a plurality of head electronic components provided on the head control board, and determine whether the head control board is powered on according to the information acquisition result for each head electronic component, and if the head electronic component is abnormal in the information acquisition result for each head electronic component, the head electronic component may not be powered on.
One of the reasons why the nozzle control plate is not electrified is: the nozzle control board is not normally connected with the nozzle power supply. The user can be after acquireing the information that the shower nozzle control panel was not gone up the electricity, detect whether normal connection is gone up with the shower nozzle power to the shower nozzle control panel, if detect the shower nozzle control panel and the shower nozzle power is not normally connected, then the user can carry out the reconnection with shower nozzle control panel and shower nozzle power to ensure that each shower nozzle electronic part homoenergetic is normally gone up.
In one embodiment, if the detection module cannot normally acquire information from any one of the head memory, the temperature sensor provided on the head control board, and the driving chip for driving the electronic components of the head, it is determined that the head control board is not powered on.
And the nozzle memory is used for storing printing information required by nozzle printing. Only after the information can be normally acquired from the head memory can it be judged that the head memory can be normally used. Only after the nozzle storage is normally used, the nozzle can acquire information required by printing from the nozzle storage in the printing process, and the printing can be guaranteed to be smoothly carried out.
And the temperature sensor is used for measuring the internal temperature of the spray head and can measure the temperature of the spray head in real time in the working process of the spray head. According to whether the temperature signal obtained from the temperature sensor is normal or not, whether the nozzle control board is electrified or not can be judged. If the temperature signal obtained from the temperature sensor is abnormal, the situation that the nozzle control plate is not normally electrified and the nozzle is abnormal and is not suitable for printing operation can be judged. Only after the temperature signal obtained from the temperature sensor is normal, the printing process of the spray head can be guaranteed not to be in accident, the spray head can be judged to be normally started, and follow-up operation can be carried out.
And the driving chip is used for driving the electronic components of the spray head. Whether the electronic parts of the head can work normally is related to whether the head can operate. Therefore, whether the driving chip is normal or not directly determines whether the spray head can perform subsequent operation or not. After the shower nozzle starts, whether need judge driver chip normal earlier, if driver chip is unusual, then can judge that the shower nozzle control panel does not go up the electricity, the shower nozzle can't carry out follow-up printing, the shower nozzle starts the failure.
Therefore, only after the signal can be normally acquired from the sprayer memory, and the information acquired from the temperature sensor inside the sprayer and the driving chip used for driving the electronic components inside the sprayer is normal, the sprayer control board can be judged to be electrified, and the sprayer can normally work. Only after the nozzle control board is judged to be electrified according to the nozzle storage, the temperature sensor inside the nozzle and the driving chip used for driving the electronic components inside the nozzle, the nozzle control board can be finally judged to be electrified, and the nozzle can be used for carrying out subsequent operation.
