Detailed Description
Referring to fig. 1, fig. 1 is a block diagram of an electronic device according to an embodiment of the invention.
In this embodiment, the electronic device 10 of the present invention is suitable for a start control system, and the electronic device 10 includes: a storage unit 101, a control unit 102, an energy 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 energy consumption unit 104, the communication module 105, and the power supply 20, and the communication module 105 is communicatively connected to the external control terminal 30.
In this embodiment, the electronic device 10 has a device identifier, the delay unit 103 may be configured to provide a random delay time segment, the control unit 102 may enable the energy consumption unit 104 according to the random delay time segment, and the storage unit 101 may store data such as a random number table, a control program, and the device identifier. For example, when the electronic device 10 is connected to the power source 20 and turned on (i.e. the so-called power-on), the control unit 102 may detect the power source start, and the control unit 102 may calculate and simulate the random delay to provide the random delay time segment by running the control program to make the delay unit 103 implemented in software. The random delay time segment may be, for example, any time length selected from 0ms to 100ms, for example: any time length of 21ms, 30ms, 57ms, 100ms, etc., but it should be noted that, although the embodiment of the present invention is described above, the present invention is not limited to the time length described. Then, the control unit 102 may enable the energy consuming portion 104 after a random delay time according to the random delay time interval provided by the delay unit 103, and then the energy consuming portion 104 enters the start-up time interval and generates a first load (i.e. a so-called start-up load), and then the energy consuming portion 104 enters the stable operation interval and generates a second load after a period of time (e.g. 10 ms). The first load is greater than the second load, that is, the starting load of the electronic device is greater than the load generated during the stable operation. Therefore, when the start control system includes a plurality of electronic devices 10, even if the plurality of electronic devices 10 are started at one time, the start time of the plurality of electronic devices 10 can be respectively and independently dispersed in a random delay manner by the framework of the invention, so that the problem that the power supply 20 is overloaded due to the simultaneous start of a large number of electronic devices 10 is avoided.
In the present invention, the storage unit 101 refers to a device for storing data such as a random number table, a control program, and a device identification code, for example, the storage unit 101 may be a nonvolatile memory, a memory card, a buffer, or other devices having the same function, and the types of the storage devices listed are only examples, and the present invention is not limited thereto, and all storage devices having the same function may be used as the storage unit 101 of the present invention.
The control unit 102 refers to a device that is a processing core of the electronic device 10 and can be used to execute and access control programs and data stored in the storage unit 101. For example, the control Unit 102 may be a single chip microcomputer (MCU, microController Unit), a central processing Unit (CPU, central Processing Unit), a screen zoom controller (Scaler), or other devices with the same functions, and the types of the devices listed are only examples, and the invention is not limited thereto.
In the present invention, the energy dissipation portion 104 refers to an energy dissipation component that generates a high start load at the moment of starting as a part of the electronic device 10. For example, the energy consumption unit 104 may be, for example, a backlight module of a display device, or a motor device, and the listed energy consumption structure types are only examples, which are not limited in the present invention. The electronic device 10 may further include a control portion (the control unit 102 is one of embodiments), where the control portion may not enable the energy consumption portion 104 but only enable the control portion when the electronic device 10 is connected to a power source, and the control portion may be communicatively connected to the external control terminal 30, for example, by means of the communication module 105, the external control terminal 30 may transmit a control instruction to the control unit 102 through the communication module 105, and enable the energy consumption portion 104 according to the control instruction of the external control terminal 30, that is, the control unit 102 may enable the energy consumption portion 104 according to the control instruction when receiving the control instruction (that is, start the energy consumption portion 104 and make the energy consumption portion 104 enter the start time zone).
In this embodiment, the electronic device 10 of the present invention can provide a random delay time segment according to the random table by the delay unit 103. Further, when the delay unit 103 is implemented in software, a random number sequence needs to be generated in advance. For example, the control unit 102 may generate one or more random numbers in advance, use the device identification code and a value in an Electrically Erasable Programmable Read Only Memory (EEPROM)/Flash Memory (Flash Memory) as a seed code (seed) of the random numbers in the random numbers, and accumulate and store the value as a next calculated random number after each use, that is, the control unit 102 may update the first random number in the random numbers to the second random number according to the device identification code and the Memory data. In one embodiment, the storage unit 101 stores an algorithm, and the control unit 102 may dynamically generate the random number table according to the algorithm.
Next, the distribution of the random delay time zone is explained below. In this embodiment, the delay unit 103 may provide a plurality of random delay time segments, and the random delay time segments are distributed in a normal state. For example, the delay unit 103 may limit the provided random delay time section within a distribution interval, for example, the distribution interval may have a distribution lower limit of 0ms and a distribution upper limit of 100ms, in which case the random delay time section length provided by the delay unit 103 may be limited to any time length from 0ms to 100 ms. While a typical untreated stochastic numerical computational simulation will exhibit a normal distribution, even if 68% of the stochastic delay time falls within a standard deviation time, it will be dispersed over multiple delay time intervals within the standard deviation time, reducing the likelihood of collisions (i.e., providing similar delay time lengths). In one embodiment, to avoid collision, the delay unit 103 provides a plurality of random delay time segments using the device id and the memory data, and the random delay time segments are distributed in an average manner, so as to further reduce the possibility of collision.
Next, referring to fig. 2, fig. 2 is a block diagram of an electronic device according to another embodiment of the invention.
The present invention provides various embodiments. In the embodiments of the present invention, the components/devices denoted by the same reference numerals may also include the same functions as those of other embodiments, so that detailed description thereof will not be repeated in the embodiments of the present invention, and only the differences from the other embodiments are described, so that the matters mentioned in the embodiments may be rearranged and combined as long as no conflict arises, and the present invention is not limited to the enumerated embodiments.
In this embodiment, the electronic device 10 of the present invention is suitable for a start control system, and the electronic device 10 includes: a storage unit 101, a control unit 102, a delay unit 103, an energy consumption unit 104, and a communication module 105. The control unit 102 is connected to the storage unit 101, the delay unit 103, the energy consumption unit 104, the communication module 105, and the power supply 20, and the communication module 105 is communicatively connected to the external control terminal 30.
In the present embodiment, the delay unit 103 is implemented in hardware, and the delay unit 103 includes: noise amplification circuitry, and analog to digital conversion circuitry, and is configured to provide a random delay time segment based on the supply noise of the power supply 20. In this embodiment, the delay unit 103 may be connected to the power supply 20 and obtain a power noise signal having randomness with respect to the dc level by using the power noise of the power supply input terminal, thereby providing a random delay time section. For example, the power supply 20 may be connected to a capacitor, the noise amplifying circuit is connected to the capacitor and the adc circuit, and the capacitor is connected in series to the delay unit 103, wherein the capacitor may filter the dc signal of the power supply 20 and leave the power supply noise, and the noise amplifying circuit amplifies the power supply noise to obtain a random dc level, and the adc circuit provides a random delay time section according to the random dc level.
Next, referring to fig. 3, fig. 3 is a block diagram of a start control system 1 according to an embodiment of the invention.
In the present embodiment, the start control system 1 includes a plurality of electronic devices 10, an external control terminal 30, and a common power source 21, wherein the plurality of electronic devices 10 are connected to the external control terminal 30 and the common power source 21.
For example, the external control terminal 30 may be a control center, and the external control terminal 30 may send control instructions to each electronic device 10 simultaneously and enable the power consumption units in each electronic device 10 with random delay. Under the conventional system architecture, if the control center is used to disperse the enabling time (start-up time) of the energy consumption part in each electronic device 10, the control circuit of each electronic device 10 must be connected to the control center in advance, and in addition, the control center must also allocate the start-up sequence/time of each electronic device in advance. Compared with the conventional system, the start control system 1 of the present invention omits complicated circuit configuration and programming, the start control system 1 does not need to connect the control circuit of each electronic device 10 to the control center in advance (or the control command received by the control unit/control portion does not include the time parameter), and when the electronic device 10 is started, the electronic device 10 enables the energy consumption portion according to the random delay time section provided by the delay unit, thereby achieving the technical effect of reducing the circuit configuration.
In summary, the start-up control system of the present invention includes a plurality of electronic devices, and the start-up control system of the present invention can enable the energy consumption portion in a random delay manner by means of the random delay time section provided by the delay unit, thereby avoiding overload problems caused by simultaneous start-up of the plurality of electronic devices, and further achieving the technical effects of reducing the load of the power supply system, reducing the circuit configuration (e.g. omitting the connection with the control center), reducing the load capacity, etc.
While the invention has been described with respect to preferred embodiments, it will be understood by those skilled in the art that various changes and modifications may be made without departing from the spirit and scope of the invention, and that any such changes and modifications as described in the above embodiments are intended to be within the scope of the invention.
