Description

Technical Field

[0001] This invention relates to an electronic device and a startup control system, and more particularly to a startup control system that controls the startup time of an electronic device in a random manner, thereby preventing multiple electronic devices from starting simultaneously, wherein the startup load of the electronic device is greater than the stable load. Background Technology

[0002] For example, in a shopping mall or other business premises, multiple display devices (electronic devices) may be set up and need to be turned on before the start of business hours each day to carry out the business activities required for operation.

[0003] However, due to the large number of electronic devices, businesses often choose to connect these devices to a control center and start up a large number of electronic devices at the same time through the control center. Furthermore, since electronic devices such as display devices and motors generate a load (i.e., high starting current) that is much greater than that during stable operation when starting up, starting up a large number of electronic devices at the same time will cause an additional burden on the power supply system and potentially endanger the electrical safety of users.

[0004] To avoid electrical safety issues, power supply systems are forced to increase backup capacity, which leads to increased design costs. At the same time, excess backup capacity also causes unnecessary waste of resources. Summary of the Invention

[0018] Figure 3 This is a block diagram of a startup control system provided in an embodiment of the present invention. Detailed Implementation

[0019] Please refer to Figure 1 , Figure 1 This is a block diagram of an electronic device provided according to an embodiment of the present invention.

[0020] In this embodiment, the electronic device 10 of the present invention can be applied to a start control system. The electronic device 10 includes: a storage unit 101, a control unit 102, a power consumption unit 104, and a communication module 105. The control unit 102 includes a delay unit 103, and the control unit 102 is connected to the storage unit 101, the power consumption unit 104, the communication module 105, and the power supply 20. The communication module 105 is communicatively connected to an external control terminal 30.

[0021] In this embodiment, the electronic device 10 has a device identification code, the delay unit 103 can be used to provide a random delay time segment, the control unit 102 can enable the power consumption unit 104 according to the random delay time segment, and the storage unit 101 can store data such as a random number table, a control program, and the device identification code. For example, when the electronic device 10 is connected to and powered on by the power supply 20 (i.e., power-on), the control unit 102 can detect the power-on, and the control unit 102 can use the control program to make the delay unit 103 software-based, calculating and simulating a random delay to provide a random delay time segment. The random delay time segment can be any time length selected from 0ms to 100ms, such as 21ms, 30ms, 57ms, 100ms, etc. However, it should be noted that although the embodiments of the present invention are described above, the present invention is not limited to the time lengths mentioned. Next, the control unit 102 can enable the power consumption unit 104 after a random delay period, based on the random delay time range provided by the delay unit 103. The power consumption unit 104 then enters the startup time range and generates a first load (i.e., the startup load). After a period of time (e.g., 10ms), the power consumption unit 104 enters the stable operating range and generates a second load. The first load is greater than the second load; that is, the startup load of the electronic device is greater than the load generated during stable operation. Therefore, when the startup control system includes multiple electronic devices 10, even if multiple electronic devices 10 are started at once, the startup time of each electronic device 10 can be independently distributed through random delays using the architecture of this invention, avoiding the problem of power supply 20 overload caused by the simultaneous startup of a large number of electronic devices 10.

[0022] In this invention, storage unit 101 refers to a device for storing data such as a random number table, control program, and device identification code. For example, storage unit 101 can be non-volatile memory, memory card, cache, or other devices with the same function. The listed types of storage devices are only examples, and this invention is not limited thereto. All storage devices with the same function can be used as storage unit 101 of this invention.

[0023] In this invention, control unit 102 refers to a device that serves as the processing core of electronic device 10 and can be used to execute and access control programs and data stored in storage unit 101. For example, control unit 102 may be a microcontroller (MCU), a central processing unit (CPU), a screen scaling controller, or other devices with the same function. The listed device types are merely examples, and this invention is not intended to limit the scope of the invention.

[0024] In this invention, the energy-consuming part 104 refers to an energy-consuming component that generates a high startup load during the startup of the electronic device 10. For example, the energy-consuming part 104 may be a backlight module of a display device or a motor device, etc. The listed energy-consuming structures are merely examples, and this invention is not intended to limit the scope of the invention. The electronic device 10 may also include a control unit (control unit 102 is one embodiment). When the electronic device 10 is connected to a power source, the control unit may be enabled but not the energy-consuming part 104. The control unit may be connected to an external control terminal 30 via a communication module 105, for example. The external control terminal 30 may transmit control commands to the control unit 102 through the communication module 105 and enable the energy-consuming part 104 according to the control commands of the external control terminal 30. That is, the control unit 102 may enable the energy-consuming part 104 only when it receives the control command (that is, start the energy-consuming part 104 and put the energy-consuming part 104 into the startup time period).

[0025] In this embodiment, the electronic device 10 of the present invention can provide a random delay time segment based on a random number table via a delay unit 103. Furthermore, when the delay unit 103 is implemented in software, a sequence of random numbers needs to be generated in advance. For example, the control unit 102 can generate one or more random number tables in advance, using a device identification code and values ​​from an electronically erasable programmable read-only memory (EEPROM) / flash memory as the seed code for the random number table. After each use, the value is accumulated and stored for use in the next random number calculation. That is, the control unit 102 can update the first random number value in the random number table to a second random number value based on the device identification code and memory data. In one embodiment, the storage unit 101 stores an algorithm, and the control unit 102 can dynamically generate a random number table based on the algorithm.

[0026] Next, the distribution of random delay time segments will be explained. In this embodiment, delay unit 103 can provide multiple random delay time segments, and these random delay time segments exhibit a normal distribution. For example, delay unit 103 can limit the provided random delay time segments to a distribution interval. For instance, the lower limit of the distribution interval can be 0ms, and the upper limit can be 100ms. In this case, the length of the random delay time segments provided by delay unit 103 will be limited to any time length between 0ms and 100ms. Generally, unprocessed random numerical simulations exhibit a normal distribution. Even if 68% of the random delay times fall within a standard deviation, they will still be dispersed across multiple delay time intervals within that standard deviation time, reducing the possibility of collision (i.e., similarly long provided delay times). In one embodiment, to avoid collisions, delay unit 103 uses device identification codes and memory data to provide multiple random delay time segments, and these random delay time segments exhibit an even distribution, further reducing the possibility of collisions.

[0027] Next, please refer to Figure 2 , Figure 2 A block diagram of an electronic device provided in another embodiment of the present invention.

[0028] This invention provides various implementation methods. In the various embodiments of this invention, components / devices using the same symbols to represent the functions of the components / devices may also include the same functions as in other embodiments. Therefore, in the various embodiments of this invention, the descriptions will not be repeated, but only the differences from other embodiments will be described. The matters mentioned in the various embodiments can be rearranged and combined as long as they do not conflict, and applied to the various embodiments. This invention is not limited to the listed embodiments.

[0029] In this embodiment, the electronic device 10 of the present invention can be applied to a start control system. The electronic device 10 includes: a storage unit 101, a control unit 102, a delay unit 103, a power consumption unit 104, and a communication module 105. The control unit 102 is connected to the storage unit 101, the delay unit 103, the power consumption unit 104, the communication module 105, and the power supply 20. The communication module 105 is communicatively connected to an external control terminal 30.

[0030] In this embodiment, the delay unit 103 is implemented in hardware. The delay unit 103 includes a noise amplification circuit and an analog-to-digital conversion circuit, and is used to provide a random delay time segment based on the power supply noise of the power supply 20. In this embodiment, the delay unit 103 can be connected to the power supply 20 and utilize the power supply noise at the power input terminal to obtain a power supply noise signal with randomness relative to the DC level, thereby providing a random delay time segment. For example, the power supply 20 can be connected to a capacitor, the noise amplification circuit can be connected to the capacitor and the analog-to-digital conversion circuit, and the capacitor can be connected in series to the delay unit 103. The capacitor can filter the DC signal of the power supply 20 and retain the power supply noise. After the power supply noise is amplified by the noise amplification circuit, the analog-to-digital conversion circuit obtains a random DC level and provides a random delay time segment based on the random DC level.

[0031] Next, please refer to Figure 3 , Figure 3 This is a block diagram of a start-up control system 1 provided in an embodiment of the present invention.

[0032] In this embodiment, the start control system 1 includes multiple electronic devices 10, an external control terminal 30, and a common power supply 21, wherein the multiple electronic devices 10 are connected to the external control terminal 30 and the common power supply 21.

[0033] For example, the external control terminal 30 can be a control center, and the external control terminal 30 can simultaneously send control commands to each electronic device 10 and enable the power-consuming parts in each electronic device 10 in a random delay manner. In the architecture of a conventional system, if the power-consuming parts in each electronic device 10 are to be distributed by the control center, the control circuit of each electronic device 10 must be connected to the control center in advance. In addition, the control center must also pre-allocate the startup sequence / time of each electronic device. Compared with the conventional system, the startup control system 1 of the present invention eliminates the complicated circuit configuration and program design planning. The startup control system 1 does not need to pre-connect the control circuit of each electronic device 10 to the control center (or the control commands received by the control unit / control department do not include time parameters). When the electronic device 10 is started, the electronic device 10 enables the power-consuming parts according to the random delay time segment provided by the delay unit, thereby achieving the technical effect of reducing circuit configuration.

[0034] In summary, the startup control system of the present invention includes multiple electronic devices. The startup control system of the present invention can enable the power consumption unit in a random delay manner by means of a random delay time segment provided by the delay unit, thereby avoiding the overload problem caused by the simultaneous startup of multiple electronic devices, and thus achieving the technical effects of reducing the burden on the power supply system, simplifying the wiring configuration (for example, eliminating the need for connection with the control center), and reducing the backup capacity.

Any person skilled in the art can make some modifications or alterations to the methods and techniques disclosed above without departing from the scope of the present invention to create equivalent embodiments.
