Detailed Description

Reference will now be made in detail to the exemplary embodiments, examples of which are illustrated in the accompanying drawings. When the following description refers to the accompanying drawings, like numbers in different drawings represent the same or similar elements unless otherwise indicated. The implementations described in the exemplary embodiments below are not intended to represent all implementations consistent with the present disclosure.

In operation, in one example, a printing device is typically used to print a document. A plurality of consumable boxes (such as consumable boxes with four colors of black, cyan and red and yellow) need to be loaded simultaneously when the printing equipment prints files, corresponding printing chips are arranged on each consumable box, and the printing equipment is communicated with four printing chips (KCMY), authenticated and the like simultaneously during working. In the prior art, in the communication process between the printing device and the four printing chips, after a power supply Voltage (VCC) is powered on, the four printing chips all receive an electric signal and are started basically at the same time, and printing is completed. However, in the prior art, since the four printing chips are started up basically at the same time, power consumption is superposed and the output voltage of the printing device is pulled down, so that loading failure of the printing chips is caused, and further printing failure is caused.

The application provides a chip start control method, a control circuit, a chip set, an imaging box set and a device, and aims to solve the technical problems in the prior art.

The following describes the technical solution of the present application and how to solve the above technical problems in detail by specific embodiments. These several specific embodiments may be combined with each other below, and details of the same or similar concepts or processes may not be repeated in some embodiments. Embodiments of the present application will be described below with reference to the accompanying drawings.

Fig. 1 is a schematic flowchart of a chip start control method provided in an embodiment of the present application, and is applied to a print chip in a printing apparatus, where the print chip is provided with a memory, and the printing apparatus has at least two print chips and at least two memories; as shown in fig. 1, the method includes:

step 101, if a preset electric signal is received, initializing a memory in a current printing chip, and determining the operation mode of the current printing chip; wherein the operation mode characterizes an operation step of the print chip.

For example, the execution main body of this embodiment may be a print chip in the printing apparatus, each print chip is provided with a memory, the number of the memories on the print chip is at least 1, may be one, or may be multiple, the memory type may be a volatile memory, or may be a non-volatile memory, without limitation, and the printing apparatus has at least two print chips and at least two memories. Preferably, when the number of the memories on the print chip is 1, the Memory may be a MRAM Memory (magnetic Random Access Memory) for storing the chip configuration information and the first delay time period; when the number of the memories on the printing chip is 2, the memory chip configuration information and the first delay time period may be stored separately, and the types of the two memories may be the same or different, and preferably, the two memories may be an MRAM memory and a fuse memory.

The MRAM memory is used for storing chip configuration information, and the fuse memory is used for storing a first delay time period.

It should be noted that the MRAM memory is a nonvolatile memory, has a high-speed read/write capability, can repeatedly write a plurality of times, can rewrite a specific value of a first delay time period when the first delay time period is stored in the MRAM, and can dynamically adjust the start delay time period of each print chip in an application of starting a group of print chips (i.e., a group of ink cartridges), control the start interval of each print chip, and determine an optimal start configuration.

The fuse in the fuse memory is generally very thin metal or polysilicon, and the fuse will be blown when a large current flows through the fuse, and the fuse can be programmed only once through whether the fuse is programmed or not, so the fuse memory is a one-time programmable memory, and after the optimal starting configuration time is determined in the test stage, the optimal first delay time can be stored in the single fuse memory, that is, before the ink cartridge is used, the fuse is blown in advance, the delay data written in each ink cartridge, that is, the delay time period, so as to realize the time-sharing starting of a group of printing chips (that is, a group of ink cartridges). Storing the delay data in a separate fuse memory may prevent the print chip or the ink cartridge from being repeatedly used multiple times, which may degrade the print quality, relative to storing the first delay time period in the MRAM memory.

In this step, if the print chip receives a preset electrical signal, the memory in the current print chip is initialized, so that the memory enters an accessible state, and the operating mode of the current print chip is determined. The operation mode represents the operation steps of the printing chip, the operation steps comprise determining the execution sequence of the first delay time period and the like, and the preset electric signal is an electric signal when the power supply voltage 0V rises to the chip reset working voltage in the communication process of the printing device.

Step 102, determining a first delay time period prestored in a memory in a current printing chip according to an operation mode; and a preset time interval exists between the first delay time period in the current printing chip and the second delay time period of another printing chip in the at least two printing chips.

Illustratively, different delay data is stored in advance in the memory of each printing chip, and the delay data may be a delay time period used for delaying the loading start time of the printing chip for loading the printing logic information. A first delay time period is stored in a memory in the current printing chip in advance, a second delay time period is stored in a memory in another printing chip in at least two printing chips in advance, and a preset time interval exists between the first delay time period and the second delay time period. The preset time interval is less than or equal to the complete time length required by the current printing chip for loading the printing logic information, and the preset time interval is equal to the complete time length required by the current printing chip for loading the printing logic information, namely the loading start time of the next printing chip is equal to the loading end time of the previous printing chip, namely the delay time periods of all the printing chips cannot be crossed; the preset time interval is smaller than the complete time length required by the current printing chip for loading the printing logic information, namely the loading start time of the next printing chip is earlier than the loading end time of the previous printing chip, namely the delay time periods of all the printing chips can be crossed.

In the step, the printing chip determines a first delay time period prestored in a memory in the current printing chip according to the operation step indicated by the operation mode, and meanwhile, because the printing device comprises at least two printing chips, another printing chip in the at least two printing chips also determines a second delay time period prestored in the memory in another printing chip according to the operation step indicated by the operation mode. Specifically, the first delay time period is determined as follows.

In a first implementation of determining the first delay time period, there are 1 MRAM memory on the print chip, and the MRAM memory is used to store chip configuration information and the first delay time period. If the operation mode is determined to be the loading-first delay mode, the chip configuration information prestored in the MRAM memory in the current printing chip is loaded and obtained firstly, and then the first delay time period is read, so that the first delay time period prestored in the memory in the current printing chip can be determined.

Or, in a second implementation manner of determining the first delay time period, 1 MRAM memory and 1 fuse memory are present on the print chip, where the MRAM memory is used to store chip configuration information, and the fuse memory is used to store the first delay time period. If the operation mode is determined to be the mode of delaying time first and then loading, a first delay time period prestored in a fuse memory in the current printing chip is read first. Then, chip configuration information prestored in an MRAM memory in the current printing chip is loaded and obtained. The chip configuration information includes basic configuration information of the print chip, for example, the chip configuration information includes a clock (OSC), a voltage (LDO), an operation mode, and the like.

For example, the first delay condition is that the delay time periods for starting loading of any two print chips do not intersect. For example, the time for loading printing logic information (loading for short) by one print chip is 50 milliseconds (ms), the first delay time period T1 pre-stored in the memory of the print chip 1 is 0ms, the second delay time period T2 pre-stored in the memory of the print chip 2 is 50ms, the third delay time period T3 pre-stored in the memory of the print chip 3 is 100 ms, and the fourth delay time period T4 pre-stored in the memory of the print chip 4 is 150 ms, that is, only one print chip is loaded at any time, the overall power consumption for starting a group of chips is the lowest, or the total time of the delay starting time periods of a group of chips can be shortened, and the second delay condition is that the delay time periods for starting loading of at least two print chips can be crossed on the premise that the power consumption is not overloaded. The time for loading the printing logic information by one printing chip is 50 milliseconds (ms), the first delay time period T1 of the printing chip 1 is set to be 0ms (ms), the second delay time period T2 of the printing chip 2 is set to be 20ms (ms), the third delay time period T3 of the printing chip 3 is set to be 40ms (ms), the fourth delay time period T4 of the printing chip 4 is set to be 60ms (ms), that is, between 0ms and 50ms, the printing chip 1, the printing chip 2 and the printing chip 3 all have coincident loading time.

103, loading printing logic information corresponding to the current printing chip according to the first delay time period to finish the printing processing of the printing equipment; wherein the printing logic information is used for indicating the printing rule information of the printing device in the printing process.

Illustratively, the printing logic information is printing rule information of the printing apparatus during printing, which is stored in advance. And the printing chips load the printing logic information corresponding to the current printing chip according to the first delay time period, and meanwhile, the other printing chip in the at least two printing chips loads the printing logic information corresponding to the other printing chip according to the second delay time period. Because the preset time interval exists between the first delay time period and the second delay time period, the loading starting time for loading the corresponding printing logic information by each printing chip is inconsistent, and then each printing chip can load the printing logic information in a staggered mode so as to finish the printing processing of the printing equipment and prevent overload caused by simultaneous loading.

For example, under the first delay condition, the four printing chips respectively load the printing logic information occupying more power consumption after respective delay time periods, and it is assumed that the printing logic information of the printing chips can be completely loaded within 50ms, that is, after the first printing chip 1 finishes loading the printing logic information, the second printing chip 2 starts to be loaded, and so on until the fourth printing chip 4 is loaded, so that the lowest startup power consumption can be ensured. Or, in the second delay condition, on the premise that power supply startup power consumption is satisfied, it is not necessary to start up loading of a subsequent print chip after a previous print chip is completely loaded, there may be temporal crossing in startup between two adjacent print chips, 20ms after print chip 1 is started up and loaded, print chip 2 is started up and loaded, 40ms after print chip 3 is started up and loaded, 50ms after print chip 1 is started up and loaded, 60ms after print chip 4 is started up and loaded, so that three print chips can be allowed to be started up simultaneously in one loading period (50 ms). Other delay time periods can also be set, for example, when the delay time period is 30ms, after the print chip 1 is started and loaded for 30ms, the print chip 2 is started and loaded, after 50ms, the print chip 1 is started and loaded, after 60ms, the print chip 3 is started and loaded, and after 90ms, the print chip 4 is started and loaded, so that 2 print chips can be started simultaneously in one loading cycle (50 ms), and the starting time of one group of chips can be reduced.

It should be noted that, the printing apparatus is exemplified by a printer, each ink cartridge in the printer is correspondingly provided with a printing chip, the printing chip records consumption information of ink or ink allowance information, if the ink in the ink cartridge is completely consumed, the ink cartridge needs to be manually replaced and the ink amount information stored in the printing chip needs to be reset, in addition, the printing chip also stores printing logic information, the printing logic information is usually set by an Original Equipment Manufacturer (OEM), and therefore, the printing logic information may also be called OEM logic. The printing logic information comprises key information, serial numbers, colors, encryption algorithm information, verification information, algorithms for communicating with the printer, information passwords, production dates and other information.

The key information provided by the embodiment of the application comprises two types, one type is the key information which is provided by an original equipment manufacturer and used for authenticating consumable materials (ink boxes) and printing equipment, and the other type is the encryption key information (chip key) of the printing chip provided by a compatible equipment manufacturer, so that the circuit in the printing chip can be prevented from being cracked by other third parties except the compatible equipment manufacturer, wherein the chip key can be arranged in the same memory together with other printing logic information, and can also be arranged in a separate memory.
