Quick boot method and electronic system

The invention relates to a booting method and an electronic system, in particular to a quick booting method and related electronic system applied to a public safety electronic system with intelligent functions.

In the Public Safety equipment market, traditional public safety equipment provides basic functions such as intercom function and anomaly detection warning function to assist in the handling of emergencies. However, public safety devices with only a single function are increasingly unable to meet the needs of today's complex environments. Just as traditional mobile phones with a single function have gradually been replaced by versatile, practical and scalable smart phones, The increase of smart platforms by traditional public safety equipment is the trend of the times.

When a public safety electronic system has a conventional public safety device and a smart device configured with one of the smart platforms, the public safety electronic system can also perform the functions of the traditional public safety device, and can also use the smart type. The device performs the related application services. However, when the power of the aforementioned public safety electronic system is turned on, it is usually necessary to wait until all the electronic devices integrated therein are turned on before entering the normal operation procedure. At this time, each electronic device in the public safety electronic system can be started. Perform related operations. In this case, since the boot time (about 20 seconds or more) of the smart device with the smart platform is usually much longer than the boot time of the conventional public safety device (within about 3 seconds). If the initialization is performed according to the traditional boot process to detect the settings of all peripheral devices of the electronic system, all peripheral devices need to wait until the entire electronic system is turned on, that is, each electronic in the aforementioned public safety electronic system. The device must wait until the electronic device with the slowest boot speed is turned on (ie, after 20 seconds) to perform related operation functions. In the case of public safety equipment that must respond quickly in an emergency, such a long boot time is completely unacceptable and does not meet the standards for the use of public safety equipment, so it is critical to speed up the startup.

Therefore, how to improve the lack of long-term boot time of the conventional dual system, so as to ensure that the public safety electronic system with intelligent platform can be quickly turned on (ie, equivalent to the boot speed of traditional public safety equipment) without sacrificing the wisdom platform. Its versatility, practicality and scalability have been one of the goals of the industry.

Therefore, the main object of the present invention is to provide a fast booting method and an electronic device, which can shorten the booting time of a public safety electronic system with a smart platform, and retain the smart platform without increasing the hardware cost. Versatility, practicality and scalability.

Please refer to FIG. 1. FIG. 1 is a schematic diagram of an electronic system 10 according to an embodiment of the present invention. The electronic system 10 is an electronic system in which a plurality of electronic devices are integrated. The electronic system 10 includes an electronic device 100 and an electronic device 102. The boot time of the electronic device 100 is less than the boot time of the electronic device 102. For example, the electronic device 100 can be a public safety device such as a public safety walkie-talkie, a fire-fighting device, or the like. The electronic device 102 can be a smart device with one of the smart platforms. When the power of one of the electronic systems 10 is turned on, the electronic device 100 and the electronic device 102 respectively start to be powered on, and after the electronic device 100 is powered on, the function of the electronic device 100 is executed according to a system main control authority MASTER. After the electronic device 102 is powered on, it enters a handover procedure to enter a normal operating procedure. In other words, the electronic device 100 that is turned on faster will be able to perform related operations according to the system main control authority MASTER immediately after the booting itself is completed, without waiting for all the electronic devices in the electronic system to complete the booting to perform the relevant operating functions.

Regarding the booting method of the electronic system 10, it can be summarized as a process 20, please continue to refer to the following description. 2 is a schematic diagram of a process 20 of an embodiment of the present invention. The process 20 is used to shorten the boot time of the electronic system 10 to achieve the effect of quickly providing an operational function of the electronic device. The process 20 includes the following steps: Step 200: Providing system main control authority to the first electronic device and providing the system The slave control authority is sent to the second electronic device. Step 202: When the power of the electronic system is turned on, the first electronic device and the second electronic device respectively start to be powered on, wherein the boot time of the first electronic device is less than that of the second electronic device. Time step 204: after the first electronic device is powered on, performing the function of the first electronic device according to the system main control authority; and step 206: after the second electronic device is powered on, entering the handover program, the first electronic device The system main control authority is transmitted to the second electronic device, and the second electronic device transmits the system slave control authority to the first electronic device to enter a normal operating procedure.

According to the process 20, in step 200, the initial state of the electronic system 10 is to first provide the system main control authority MASTER to the electronic device 100 and the system slave control authority SLAVE to the electronic device 102. In step 202, when one of the electronic systems 10 is powered on, the electronic device 100 and the electronic device 102 respectively start to boot, and each initializes their respective environments (ie, each detects its peripheral device and executes an initialization program). Since the boot time of the electronic device 100 is less than the boot time of the electronic device 102, in step 204, after the electronic device 100 is first turned on, the electronic device 100 can start executing its own related operational functions according to the system main control authority MASTER. In step 206, after the electronic device 102 is powered on, the electronic system 10 enters the handover procedure. At this time, the electronic device 100 transmits the system main control authority MASTER to the electronic device 102, and the electronic device 102 transmits the system slave control authority SLAVE to the electronic device 100, so that the electronic system 10 will enter a normal operation procedure.

Specifically, the electronic system 10 provides the system main control authority MASTER to the electronic device 100 that is turned on faster. In this way, in step 204, after the electronic device 100 is powered on, the electronic device 100 can be based on the system. The MASTER is controlled to perform its own operational functions without having to wait until all electronic devices in the electronic system are powered on to perform the relevant operational functions. For the entire electronic system 10, the electronic system 10 will It is not necessary to wait until all the electronic devices are turned on, and the function of the electronic device 100 can be started. In other words, after the electronic device 100 that is powered on is turned on, the electronic system 10 is equivalent to having completed the system booting process and can immediately provide the electronic device 100 to perform the corresponding function.

If the electronic device 100 does not need to perform its operation function after the startup is completed or has performed the required operation (for example, the electronic device 100 has performed the required operation function or the application scenario at the time does not need to use the function of the electronic device 100) The electronic device 100 enters an idle mode, waits for the demand of the next application scenario or waits to enter the handover procedure.

In step 206, after the electronic device 102 is powered on, the electronic device 102 can transmit a handover request signal to the electronic device 100 to instruct the electronic system 10 to enter the handover procedure. After the electronic system 10 enters the handover procedure, the electronic system 10 determines whether the electronic device 100 is in the idle mode. When the electronic device 100 is in the idle mode, the electronic system 10 instructs the electronic device 100 to transmit the system main control authority MASTER to the electronic device 102 according to the handover request signal, and instructs the electronic device 102 to transmit the system slave control authority SLAVE to the electronic device 100. As a result, the electronic system 10 enters a normal operating procedure. If the electronic system 10 determines that the electronic device 100 is not in the idle mode, that is, the electronic device 100 is providing a certain function to the current application scenario, then the electronic device 100 continues to perform the operation of the function until the electronic device 100 is in the idle mode, the electronic device The device 100 transmits the system main control authority MASTER to the electronic device 102, and the electronic device 102 transmits the system slave control authority SLAVE to the electronic device 100 to enter a normal operating procedure.

Further, the electronic device 100 can be a public safety device including a radio frequency module, a battery, and the like. The electronic device 102 can be a smart device with a smart platform, including a radio frequency transceiver, a wireless area module, a Bluetooth module, a liquid crystal display, a keyboard or a capacitive touch screen, a battery, and the like. The electronic system 10 can include devices commonly used in the electronic device 100 and the electronic device 102, such as a microphone, a speaker, an input device, and the like. The electronic system 10 further includes a dedicated communication interface UART for transferring data and control commands between the electronic device 100 and the electronic device 102. In this way, when the power of the electronic system 10 is turned on, the electronic device 100 And the electronic device 102 starts to boot respectively, and each of them initializes their respective environments, and only needs to prepare data and control commands required for the subsequent handover procedure. Since the boot time of the electronic device 100 is short (similar to the boot time of the conventional public safety device), when the electronic device 100 is powered on, the function is used according to the application scenario. The electronic device 102 has a long boot time. After the booting is completed, a handover request signal is transmitted to the electronic device 100 through the dedicated communication interface UART to instruct the electronic system 10 to enter the handover procedure. In the handover procedure, after the electronic device 100 is in the idle mode, the electronic device 100 transmits the system main control authority MASTER to the electronic device 102 according to the handover request signal, and the electronic device 102 also transmits the system slave control authority SLAVE to the electronic device. Device 100 to enter a normal operating procedure. In short, since the electronic device 100 has a short boot time, the electronic device 100 can perform its function after the booting is completed, so as to shorten the boot time of the entire electronic system 10.

The following further exemplifies an electronic system 10 that integrates a public safety device and a smart device having a smart platform, and assumes that the boot time of the public safety device is less than the boot time of the smart device. Public safety equipment can provide operational functions such as public safety walkie-talkies, fire-fighting equipment, and smart devices can provide relevant intelligent application services. Please refer to FIG. 3, which is a schematic diagram of the operation process of the public safety electronic system of the present invention. First, the electronic system 10 provides the system main control authority MASTER to the public safety device and the system slave control authority SLAVE to the smart device in advance. When the power of the electronic system 10 is turned on (step 300), the public safety device and the smart device respectively start to power on (steps 302, 304). Since the boot time of the public safety device is less than the boot time of the smart device, when the public safety device is first turned on, the public safety device can start executing its own related operational function according to the system main control authority MASTER (step 306). For example, according to the application scenario at the time, public safety equipment can provide functions such as intercom and fire report to achieve rapid rescue. If the public safety device does not need to perform its operational functions after the boot is completed, it will enter an idle mode, wait for the next application scenario or wait for the handover procedure.

When the smart device is powered on (step 308), the smart device transmits a handover request signal SIG to the public safety device to instruct the electronic system 10 to enter the handover procedure (step 310). After the electronic system 10 enters the handover procedure, at this time, the electronic system 10 determines whether the public safety device is in the idle mode (step 312). If so, the electronic system 10 instructs the public safety device to initiate the handover. At this time, the public safety device transmits the system main control authority MASTER to the smart device according to the handover request signal SIG (step 314). At the same time, the electronic system 10 also instructs the smart device to initiate the transfer, and the smart device transmits the system slave control authority SLAVE to the public safety device (step 318). If the public safety device is not in idle mode, the public safety device will continue to perform the current work (step 316). When the public safety device transmits the system master control authority MASTER to the smart device and receives the system slave control authority SLAVE transmitted by the smart device, the public safety device switches to a slave mode (step 322). After the smart device transmits the system slave control authority SLAVE to the public safety device and receives the system master control authority MASTER from the public safety device, the smart device switches to a master mode (step 324). At the same time, the electronic system 10 enters a normal operating procedure.

In addition, the electronic system 10 detects whether the public safety device has transmitted the system master control authority MASTER to the smart device and whether the smart device has transmitted the system slave control authority SLAVE to the public safety device to determine whether the handover procedure is completed ( Step 320). If so, it indicates that the electronic system 10 has entered a normal operating procedure. If not, step 310 is executed to perform the handover process again. Therefore, the electronic system 10 can provide the public safety device to perform the corresponding function immediately after the startup of the public safety device with the quick start, and after the smart device is powered on, the master control authority MASTER is given to the wisdom through the handover process. Type device.

In summary, in the prior art, the electronic devices in the dual system need to wait until all the electronic devices of the entire electronic system are turned on, which is so long for public safety devices that require rapid response in an emergency. The boot time is completely unacceptable. In contrast, the present invention can perform related operations according to the main control authority of the system immediately after the electronic device itself is turned on, and does not need to wait until all the electronic devices in the electronic system are turned on to perform related operation functions. In this way, the waiting time when the electronic system is turned on can be greatly shortened.

The above are only the preferred embodiments of the present invention, and all changes and modifications made to the scope of the present invention should be within the scope of the present invention.
