Description

Technical Field

[0001] This invention relates to the field of control technology, and in particular to a method, apparatus, and electronic device for preventing abnormal writing to storage media. Background Technology

[0002] Storage media refers to the carriers that store data. Currently, widely used storage media include NAND flash and EEPROM. Due to factors such as storage materials, the number of write cycles for storage media is limited. For example, NAND flash has a write cycle life of 1 million cycles, AT24C08 (EEROM) has a write cycle life of 1 million cycles, and the LPC1788's internal EEPROM has a lifespan of 100,000 cycles. If write operations are continuously performed on the storage media, it will quickly lose its memory function, resulting in a very short lifespan. Currently, storage media are widely used in equipment such as commercial air conditioners, and the lifespan of the storage media is a quality metric. Commercial air conditioners are typically connected to building control systems. The touchscreen of the commercial air conditioner receives certain control commands sent by the building control system and performs write operations on the storage media. The group control software of the building control system sometimes sends control commands periodically or frequently sends write operation control commands when the automatic control algorithm malfunctions. Frequent write operations on the storage media will affect its lifespan. Over time, this can damage the touchscreen's storage media, causing it to lose its memory function and even preventing the program from starting, thus affecting product quality. Summary of the Invention

[0030] The present invention will now be described more fully with reference to the accompanying drawings, which illustrate exemplary embodiments of the invention. The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention. The technical solutions of the present invention will be described in various aspects below with reference to the various figures and embodiments.

[0031] Figure 1 This is a flowchart illustrating an embodiment of the method for preventing abnormal writing to a storage medium according to the present invention, as shown below. Figure 1 As shown:

[0032] Step 101: Obtain the number of write operations performed on the storage medium per unit time.

[0033] There are several ways to obtain the number of write operations performed by the storage medium per unit time. For example, a variable can be set to record the number of write operations performed by the storage medium, and the variable value can be obtained periodically on a unit time basis. The number of write operations performed per unit time can be determined based on the change in the variable value.

[0034] There are various types of storage media, such as NAND Flash and EEPROM. NAND flash memory is a type of flash memory that uses a non-linear macrocell model internally, and has advantages such as large capacity and fast rewrite speed. EEPROM (Electrically Erasable Programmable Read-Only Memory) is a type of memory chip that does not lose data after power is lost.

[0035] Step 102: Determine whether the number of write operations performed exceeds the preset write count threshold.

[0036] The system allows setting a unit time and a write count threshold. The write count threshold represents the maximum number of times the device can access the storage medium within a given time period. These thresholds can be configured based on different devices, communication methods, user habits, and storage medium types. For example, the unit time can be set to 10-120 seconds (default is 60 seconds), and the write count threshold can be set to 5-60 times (default is 15 times). Both the unit time and write count thresholds can be set via the touchscreen module, a host computer system, or other devices.

[0037] Step 103: If the number of write operations performed exceeds a preset write count threshold, the received write data to the storage medium is written to the storage medium with a delay; if the number of write operations performed does not exceed the preset write count threshold, the received write data to the storage medium is written to the storage medium immediately.

[0038] In one embodiment, there are several ways to obtain the number of write operations performed by the storage medium within a unit of time. A detection period is set based on the unit of time, and the number of write operations performed by the storage medium within the detection period is periodically obtained. By determining whether the number of written operations exceeds a preset write count threshold, it is determined whether the write operations on the storage medium are normal. For example, if the unit of time is set to 60 seconds, the detection period is 60 seconds, and the number of write operations performed by the storage medium within this 60-second period is periodically obtained every 60 seconds.

[0039] If the number of write operations exceeds the preset write count threshold, an anomaly is detected, and the write operation is automatically delayed for a certain period. The delay time can be set, for example, from 3 to 60 minutes, with a default delay of 30 minutes. The delay time can be calculated based on the selected storage medium and its lifespan. If the number of write operations does not exceed the preset write count threshold, the write operation can be processed normally, and the data is immediately written to the storage medium. Read operations on the storage medium do not require control, as they do not damage the storage medium.

[0040] Instantaneous writing refers to writing data immediately upon receipt. Delayed writing can be achieved in several ways. For example, a delayed write period can be set according to a preset delay interval. The delay interval is the delay time, which can range from 3 to 60 minutes, with a default of 30 minutes. Data received within the delayed write period is periodically written to the storage medium according to the delayed write period. For example, with a 30-minute delayed write period, data received within each 30-minute interval is periodically written to the storage medium.

[0041] The data received during the delayed write cycle can be stored in the cache module. According to the delayed write cycle, the write data is periodically retrieved from the cache module and written to the storage medium. For example, if the delayed write interval is 30 minutes, and the number of write operations exceeds a preset write count threshold, a delayed write operation is initiated, and a timer starts. Three write data entries received at 5 minutes, 7 minutes, and 15 minutes are placed in the cache module. When the timer reaches 30 minutes, the three write data entries are read from the cache module and written to the storage medium. After the device is powered off and on again, the data is read from the storage medium and placed into the cache module. Data can then be read from the cache module for display and other operations.

[0042] If the number of write operations performed exceeds a preset write count threshold, an anomaly is detected, and the acquisition of the number of write operations performed on the storage medium within a unit of time is stopped. If a detection and recovery control command is received, the number of write operations performed on the storage medium within a unit of time is acquired again, and it is determined whether the number of write operations performed exceeds the preset write count threshold. If it does, the received write data to the storage medium is written to the storage medium with a delay; otherwise, the received write data to the storage medium is written to the storage medium immediately. In other words, upon receiving the detection and recovery control command, the normal processing flow is resumed. The detection and recovery control command can be sent by the host computer system or by the touchscreen module, etc.

[0043] If the number of write operations exceeds a preset write count threshold, an alarm message is generated and a notification is issued. The alarm message can be in various formats, including text and audio-visual alerts. For example, the alarm message could be the text "Please check if the host computer communication write operation is abnormal." This message can be displayed on a screen or sent to a host computer system (such as a building control system or other devices). It can remind the user to check if the building monitoring communication data is normal and to avoid frequent write operations.

[0044] The communication module can receive write data, detect and recover control commands, or send alarm messages to the host computer system. Communication modules include bus modules, Bluetooth modules, and Wi-Fi communication modules. The communication module can receive or send data wirelessly or via wired connections. Bus modules can include RS485 bus modules and CAN bus modules. The touchscreen module can display alarm messages or receive configuration commands and detect and recover control commands. Configuration commands can be user-inputted settings for unit time, write count thresholds, and delayed write intervals.

[0045] In one embodiment, such as Figure 2 As shown, the device for preventing abnormal writing to storage media provided by the present invention includes a detection module 11 and a control module 12. The detection module 11 and the control module 12 can be implemented as a microcontroller, a single-board computer, a PLC, an integrated circuit module, etc.

[0046] The detection module 11 acquires the number of write operations performed by the storage medium 13 within a unit time. The control module 12 is electrically connected to both the detection module 11 and the storage medium 13, and determines whether the number of write operations performed exceeds a preset write count threshold. If so, the control module 12 writes the received write data to the storage medium 13 with a delay; otherwise, the control module 12 writes the received write data to the storage medium 13 immediately.

[0047] In one embodiment, such as Figure 3 As shown, the device for preventing abnormal writing to the storage medium also includes: a delay timer module 14, a cache module 15, a communication module 16, a touch screen module 17, and a detection timer module 18.

[0048] The delay timer module 14 is electrically connected to the control module 12 and sets the delay write period according to a preset delay write time interval. The control module 12 triggers the delay timer module 14 to start timing. When the duration of the delay timer module 14 reaches the delay write time interval, the delay timer module 14 sends an execution signal to the control module 12, so that the control module 12 periodically writes the write data received within the delay write period to the storage medium 13 according to the delay write period.

[0049] The cache module 15 is electrically connected to the control module 12. The control module 12 stores the write data received during the delayed write cycle in the cache module 15. The control module 12 periodically retrieves write data from the cache module 15 and writes it to the storage medium according to the delayed write cycle.

[0050] The detection timer module 18 is electrically connected to the detection module 11, and the detection period is set according to the unit time. The detection module 11 triggers the detection timer module 18 to start timing. When the timing duration of the detection timer module 18 reaches the unit time, the detection timer module 18 sends a detection signal to the detection module 11, so that the detection module 11 periodically obtains the number of write operations performed on the storage medium within the detection period according to the detection period.

[0051] When the number of write operations performed exceeds a preset write count threshold, the control module 12 controls the detection module 11 to stop acquiring the number of write operations performed on the storage medium within a unit time. If the control module 12 receives a detection recovery control command, it controls the detection module 11 to reacquire the number of write operations performed on the storage medium within a unit time and determines whether the number of write operations performed exceeds the preset write count threshold. If the control module 12 determines that the number of write operations performed exceeds the preset write count threshold, it generates an alarm message and provides a reminder based on the alarm message.

[0052] The communication module 16 is electrically connected to the control module 12. The control module 12 receives write data, detection and recovery control commands, or sends alarm messages to the host computer system via the communication module 16. The communication module 16 includes a bus module, a Bluetooth module, and a WIFI communication module. The touchscreen module 17 is electrically connected to the control module 12, displaying alarm messages sent by the control module 12 or receiving setting commands and detection and recovery control commands.

[0053] According to another aspect of the present invention, an electronic device is provided, comprising: a storage device and means for preventing abnormal writing to the storage medium as in any of the preceding embodiments. The electronic device may be a touchscreen device in an air conditioning unit, etc.

[0054] In one embodiment, multiple large air conditioning units on a subway line are connected to the same building monitoring system. The original building monitoring system uses a timed write operation every 300ms to control the chilled water outlet temperature. Using the method, apparatus, and electronic equipment of this invention to prevent abnormal writes to the storage medium, problems with the building monitoring system's own program can be quickly identified during debugging, preventing serious losses and protecting the storage medium and the air conditioning units.

[0055] The method, apparatus, and electronic device for preventing abnormal writing to the storage medium in the above embodiments determine whether the number of write operations performed on the storage medium within a unit time exceeds a preset write count threshold. If so, the received write data to the storage medium is written to the storage medium with a delay; otherwise, the received write data to the storage medium is written to the storage medium immediately. This allows for flexible write operations based on the current write status of the storage medium, protecting the storage medium with a delay, and reminding users to check for any abnormalities. This improves the lifespan of the storage medium and the quality of the product, enhances product intelligence, and improves the user experience.

[0056] The methods and systems of the present invention may be implemented in many ways. For example, they may be implemented by software, hardware, firmware, or any combination of software, hardware, and firmware. The above-described order of steps for the method is for illustrative purposes only, and the steps of the method of the present invention are not limited to the order specifically described above unless otherwise specifically stated. Furthermore, in some embodiments, the present invention may also be implemented as a program recorded on a recording medium, the program comprising machine-readable instructions for implementing the method according to the present invention. Thus, the present invention also covers recording media storing programs for performing the method according to the present invention.

[0057] The description of this invention is given for illustrative and descriptive purposes only and is not intended to be exhaustive or to limit the invention to the forms disclosed. Many modifications and variations will be apparent to those skilled in the art.
