Description

Technical Field

[0001] The present application relates to the field of testing technology, and in particular to a device and method for detecting the alarm response time of a perimeter intrusion alarm system. Background Art

[0002] The perimeter intrusion alarm system is one of the commonly used security systems in important places such as railways, airports, government agencies, protected areas, schools, hospitals, etc. The perimeter intrusion alarm system is a system that uses sensor technology and electronic information technology to detect illegal entry or attempted illegal entry into the defense area. It is used to prevent perimeter intrusion incidents. It is generally composed of front-end detection sensors, data transmission lines and back-end alarm system software. The front-end detection sensor is generally installed on the perimeter or at the edge of the perimeter, and the back-end alarm system software is generally installed on a computer in a monitoring room far away from the perimeter.

[0003] "Alarm response time" is one of the important indicators to measure the detection performance of perimeter intrusion alarm system. According to the requirements of "Technical Standards for Security Engineering" (GB50348), the alarm response time of perimeter intrusion alarm system with security level 4 should be no more than 2 seconds, and the alarm response time of perimeter intrusion alarm system with security levels 2 and 3 should be no more than 5 seconds, that is: when someone illegally enters or attempts to illegally enter the defense area, the perimeter intrusion alarm system should alarm within 2 seconds or 5 seconds.

[0004] For a long time, the detection of the "alarm response time" performance indicator of perimeter intrusion alarm systems has been unscientific and inaccurate. Summary of the invention

[0005] Embodiments of the present disclosure provide a device and method for detecting the alarm response time of a perimeter intrusion alarm system.

[0006] In the first aspect, an embodiment of the present disclosure provides a detection device for the alarm response time of a perimeter intrusion alarm system, comprising: a first timing component, a second timing component, a simulated intrusion component and a calculation component; the first timing component is used to receive and parse the radio signal output by the satellite navigation system, keep time for the obtained world standard time, and send the obtained first timing time to the calculation component; the second timing component is used to receive and parse the radio signal output by the satellite navigation system, keep time for the obtained world standard time, and compare the obtained second timing time with the preset start time, and in response to determining that the second timing time is consistent with the preset start time, send a control instruction to the simulated intrusion component; the simulated intrusion component is used to initiate a simulated intrusion behavior towards the perimeter when receiving the control instruction, so that the perimeter intrusion alarm system alarms based on the simulated intrusion behavior; the calculation component is used to determine the alarm time of the perimeter intrusion alarm system according to the first timing time; and determine the alarm response time of the perimeter intrusion alarm system according to the preset start time and the alarm time.

[0007] In a second aspect, an embodiment of the present disclosure provides a method for detecting the alarm response time of a perimeter intrusion alarm system, comprising: controlling a first timing component to receive and parse the radio signal output by a satellite navigation system, keeping time for the obtained world standard time, and obtaining a first timing time; controlling a second timing component to receive and parse the radio signal output by a satellite navigation system, keeping time for the obtained world standard time, and comparing the obtained second timing time with a preset start time, and in response to determining that the second timing time is consistent with the preset start time, sending a control instruction to a simulated intrusion component; controlling the simulated intrusion component to initiate a simulated intrusion behavior toward the perimeter when receiving the control instruction, so that the perimeter intrusion alarm system alarms based on the simulated intrusion behavior; controlling the calculation component to determine the alarm time of the perimeter intrusion alarm system according to the first timing time; and determining the alarm response time of the perimeter intrusion alarm system according to the preset start time and the alarm time.

[0008] By applying the technical solution disclosed in the present invention, the UTC time and nanosecond or picosecond pulse frequency signals output by the extremely accurate satellite navigation system's onboard atomic clock can be used for high-precision timekeeping, which greatly reduces the detection error of the alarm response time of the perimeter intrusion alarm system and improves the timekeeping accuracy. It solves the problem that the existing detection device does not support millisecond-level time synchronization detection, and improves the detection accuracy.

[0016] It should be noted that the following detailed descriptions are exemplary and are intended to provide further explanation of the present disclosure. Unless otherwise specified, all technical and scientific terms used herein have the same meanings as those commonly understood by those skilled in the art to which the present disclosure belongs.

[0017] It should be noted that the terms used herein are only for describing specific embodiments and are not intended to limit the exemplary embodiments according to the present disclosure. As used herein, unless the context clearly indicates otherwise, the singular form is also intended to include the plural form. In addition, it should be understood that when the terms "comprising" and / or "including" are used in this specification, it indicates the presence of features, steps, operations, devices, components and / or combinations thereof.

[0018] In the absence of conflict, the embodiments in the present disclosure and the features in the embodiments may be combined with each other.

[0019] In order to make the technical solutions and advantages of the present disclosure more clearly understood, the present disclosure is further described in detail below in conjunction with the accompanying drawings and specific embodiments.

[0020] Figure 1 An exemplary system architecture 100 is shown to which an embodiment of the apparatus for detecting alarm response time of a perimeter intrusion alarm system or a method for detecting alarm response time of a perimeter intrusion alarm system of the present disclosure can be applied.

[0021] like Figure 1As shown, the system architecture 100 may include a satellite navigation system 101 , a perimeter 102 , a perimeter intrusion alarm system 103 , and a detection device 104 for the alarm response time of the perimeter intrusion alarm system.

[0022] The satellite navigation system 101 and the detection device 104 may communicate via radio, the perimeter intrusion alarm system 103 may monitor the perimeter 102, and the perimeter intrusion alarm system 103 and the detection device 104 may communicate via wired or wireless means.

[0023] Specifically, the satellite navigation system 101 can send a GNSS (Global Navigation Satellite System) signal to the detection device 104. The GNSS signal includes 3D coordinates, speed, and time information. The detection device 104 can keep time according to the time information in the GNSS signal to obtain higher-precision millisecond-level time information.

[0024] The enclosure 102 can be a security defense net for important places such as railways, airports, government agencies, protection areas, schools, hospitals, etc. It can be composed of V-shaped bracket columns, reinforced welded sheet nets, security anti-theft connectors and hot-dip galvanized blade barbed wire cages, or it can be other forms of enclosures such as brick walls and steel plate nets.

[0025] The perimeter intrusion alarm system 103 may be an electronic system or network that utilizes sensor technology and electronic information technology to detect and indicate illegal entry or attempted illegal entry into a defense area, process alarm information, and send out alarm information.

[0026] The detection device 104 can record the alarm time of the perimeter intrusion alarm system 103. At the same time, the detection device 104 can also start a simulated intrusion behavior towards the perimeter 102, so that the perimeter intrusion alarm system 103 can alarm based on the simulated intrusion behavior. By comparing the start time of the simulated intrusion behavior and the recorded alarm time, the alarm response time of the perimeter intrusion alarm system 103 can be obtained.

[0027] Figure 2 FIG. 1 is a schematic diagram showing a structure of an embodiment of a detection device for alarm response time of a perimeter intrusion alarm system disclosed in the present invention. Figure 2 As shown, the detection device 200 of the alarm response time of the perimeter intrusion alarm system of this embodiment may include: a first timekeeping component 201, a second timekeeping component 202, an intrusion simulation component 203 and a calculation component 204.

[0028] The first timekeeping component 201 is used to keep time according to the received radio signal output by the satellite navigation system, and send the obtained first timekeeping time to the calculation component 204. Specifically, the first timekeeping component 201 and the calculation component 204 can be connected by wire or wireless. When the first timekeeping component 201 is set indoors, it can be connected to the calculation component 204 by wire. When the first timekeeping component 201 is set outdoors, it can be connected to the calculation component 204 by wireless.

[0029] In some specific practices, the satellite receiving antenna of the first timing component 201 is set outdoors. In order to reduce the delay of data transmission between the first timing component 201 and the computing component 204, the first timing component 201 and the computing component 204 preferably communicate via wired mode.

[0030] The second timekeeping component 202 is used to keep time according to the received radio signal output by the satellite navigation system, and compare the obtained second timekeeping time with the preset start time. When it is determined that the second timekeeping time is consistent with the preset start time, a control instruction is sent to the simulated intrusion component 203. Here, the preset start time is the start time of the simulated intrusion behavior. The above start time can be pre-set by a technician, or it can be generated by itself according to the actual application scenario. For example, the preset start time can be 5 minutes after power-on, or at a fixed time every day. Specifically, the second timekeeping component can have a device for receiving a set time, and the technician can set the start time through the device. Alternatively, the above start time can be sent to the second timekeeping component 202 by the calculation component 204.

[0031] In some specific practices, if the distance between the computing component 204 and the second timekeeping component 202 is relatively far, the computing component 204 and the second timekeeping component 202 may communicate with each other wirelessly.

[0032] The structures of the first timekeeping component 201 and the second timekeeping component 202 may be the same or different, but both can keep time according to the received world standard time of the satellite navigation system.

[0033] The simulated intrusion component 203 is used to initiate a simulated intrusion behavior toward the enclosure when receiving the control instruction sent by the second timing component 202, so that the enclosure intrusion alarm system can alarm based on the simulated intrusion behavior. Specifically, the simulated intrusion component 203 can move toward the enclosure to hit the enclosure, or release an attacking object toward the enclosure to cover or collide with the enclosure, or move toward the enclosure and cross the electronic defense zone boundary of the enclosure intrusion alarm system, or release an object with a large area or strong infrared characteristics from the outside of the electronic defense zone boundary of the enclosure intrusion alarm system to the inside of the boundary, or create strong vibrations on the ground near the enclosure, etc. Correspondingly, the simulated intrusion component 203 can be provided with a moving device (such as a wheel), or an attacking device (such as a mechanical arm), or an infrared characteristic simulation device (such as a soft cloth or plastic plate with a heating resistor), or a vibration output device (such as an impact drill), etc. In this way, the enclosure intrusion alarm system can alarm after detecting the above-mentioned simulated intrusion behavior.

[0034] The calculation component 204 is used to determine the alarm time of the perimeter intrusion alarm system according to the first timekeeping time sent by the first timekeeping component 201. At the same time, the alarm response time of the perimeter intrusion alarm system is determined according to the preset start time and the above alarm time. Specifically, the calculation component 204 can be set in the same room as the perimeter intrusion alarm system, or receive the alarm information output by the perimeter intrusion alarm system through the communication port. The calculation component 204 can be implemented by a single-chip microcomputer, an ARM processor, an FPGA chip, etc.

[0035] The detection device for the alarm response time of the perimeter intrusion alarm system provided by the above-mentioned embodiments of the present disclosure can use the UTC time and nanosecond or picosecond pulse frequency signals output by the extremely accurate satellite navigation system onboard atomic clock for high-precision timekeeping, which greatly reduces the detection error of the alarm response time of the perimeter intrusion alarm system and improves the timekeeping accuracy, solves the problem that the existing detection device does not support millisecond-level time synchronization detection, and improves the detection accuracy.

[0036] Continue to see Figure 3 , which shows a structural schematic diagram of another embodiment of a detection device for alarm response time of a perimeter intrusion alarm system according to the present disclosure. Figure 3 As shown, the detection device 300 of the alarm response time of the perimeter intrusion alarm system may include a first timekeeping component 301, a second timekeeping component 302, an intrusion simulation component 303 and a calculation component 304.

[0037] The first timekeeping component 301 is used to receive and analyze the radio signal output by the satellite navigation system, keep time for the obtained world standard time, and send the obtained first timekeeping time to the calculation component 304.

[0038] The second timekeeping component 302 is used to keep time according to the received and analyzed radio signal output by the satellite navigation system, and compare the obtained second timekeeping time with the preset start time. When it is determined that the second timekeeping time is consistent with the preset start time, a control instruction is sent to the simulated intrusion component 303.

[0039] The simulated intrusion component 303 is used to initiate a simulated intrusion behavior toward the perimeter when receiving a control instruction, so that the perimeter intrusion alarm system issues an alarm based on the simulated intrusion behavior.

[0040] The calculation component 304 is used to determine the alarm time of the perimeter intrusion alarm system according to the first timekeeping time; and determine the alarm response time of the perimeter intrusion alarm system according to the preset start time and the alarm time. Specifically, the calculation component 304 can be implemented by a hardware chip installed on a computer, and the hardware chip is embedded with a specified software. Through the software, the preset start time can be set or displayed on the computer through a specified page, and the obtained first timekeeping time can also be displayed. The computer can be a computer with a perimeter intrusion alarm system installed, or it can be other electronic devices independent of the computer where the perimeter intrusion alarm system is located.

[0041] In some optional implementations of this embodiment, the first timekeeping component 301 may further include: a first satellite navigation data receiving module 3011, a first timekeeping module 3012, a first processor 3013 and a first communication port 3014.

[0042] The first satellite navigation data receiving module 3011 is used to receive the radio signal of the satellite navigation system, and output the second pulse signal and the first time message to the first processor 3013 according to the world standard time. Specifically, the first satellite navigation data receiving module 3011 can receive the GNSS signal of the satellite navigation system, and output the second pulse signal and the position and time message conforming to the NMEA0183 protocol to the first processor 3013.

[0043] The first timekeeping module 3012 is used to generate a first frequency pulse signal with a period of a first preset duration, and send the first frequency pulse signal to the first processor 3013. Specifically, the first timekeeping module 3012 is used to generate a frequency pulse signal with a period of nanoseconds or picoseconds, that is, the first preset duration can be nanoseconds or picoseconds. In some specific practices, the first timekeeping module 3012 can be composed of a constant temperature active crystal oscillator, a phase-locked loop (PLL) circuit, a capacitor, a resistor, etc. The frequency accuracy and stability of the constant temperature active crystal oscillator are very high, and a stable frequency pulse signal output can be maintained for a long time. In actual use, a constant temperature active crystal oscillator with an output frequency of more than 150Mhz can be selected or a phase-locked loop (PLL) can be used to multiply the output frequency of the constant temperature active crystal oscillator to obtain a higher frequency, so that the pulse period reaches nanoseconds or picoseconds, thereby improving the timekeeping accuracy.

[0044] The first processor 3013 is used to determine the first punctual time according to the second pulse signal, the first time message and the first frequency pulse signal. In some specific practices, the first processor 3013 may be built with an embedded program for parsing the first time message to obtain the UTC time. Further, the first punctual time is obtained according to the UTC time, the second pulse signal and the first frequency pulse signal.

[0045] Since the UTC time output by the current satellite navigation systems such as Beidou, GPS, GLONASS, and Galileo is only accurate to seconds, in order to improve the detection accuracy of the perimeter intrusion alarm response time, the time accuracy needs to be increased to the millisecond level, so it is necessary to perform high-precision timekeeping on the UTC time output by the satellite navigation system. In this embodiment, the first processor 3013 can start counting the number of received first frequency pulse signals while receiving the rising edge of the second pulse signal. Then multiply the above number by the period of the first frequency pulse signal to obtain the duration of the first frequency pulse signal. Whenever the duration reaches 1 millisecond, the UTC time value is increased by 1 millisecond to obtain the first timekeeping time. It is understandable that when the first processor 3013 receives the second pulse signal sent by the first satellite navigation data receiving module 3011 again, the number of statistics previously counted can be cleared and statistics can be restarted.

[0046] The first processor 3013 can be implemented by a single-chip microcomputer, an ARM processor, an FPGA chip, etc.

[0047] The first communication port 3014 is used to send the first timekeeping time to the computing component 304. Specifically, the first communication port 3014 can be an RS232 serial port, an RJ45 network port, a USB port, or other interfaces on the computer motherboard. The first timekeeping component 301 can be connected to the computing component 304 by communication using an RS232 serial port cable, a network cable, a USB data cable, or the like.

[0048] Similarly, the second timing component 302 may further include: a second satellite navigation data receiving module 3021 , a second timing module 3022 , a second processor 3033 and a second communication port 3034 .

[0049] The second satellite navigation data receiving module 3021 is used to receive a radio signal from a satellite navigation system, and output a pulse per second signal and a second time message to the second processor 3033 according to the radio signal.

[0050] The second timing module 3022 is used to generate a second frequency pulse signal with a period of a second preset time length, and send the second frequency pulse signal to the second processor 3033.

[0051] The second processor 3033 is used to determine the second timekeeping time according to the second pulse signal, the second time message and the second frequency pulse signal; and generate a control instruction when the second timekeeping time is consistent with the preset start time.

[0052] The second communication port 3034 is used to send control instructions to the simulated intrusion component 303 .

[0053] The timekeeping principle of the second timekeeping component 302 can be the same as the timekeeping principle of the first timekeeping component 301, that is, the principle by which the second timekeeping component 302 obtains the second timekeeping time is the same as the principle by which the first timekeeping component 301 obtains the first timekeeping time, which will not be repeated here.

[0054] In some optional implementations of this embodiment, the first timekeeping component 301 and the second timekeeping component 302 may further include a battery. The battery may supply power to the first timekeeping component 301, the second timekeeping component 302, and the simulated intrusion component 303. Here, the battery may supply power to the simulated intrusion component 303 continuously or upon receiving an instruction.

[0055] In some specific practices, it takes a certain amount of time for the electronic device to stabilize from the beginning of power on to normal operation. In order to avoid the power supply stabilization time causing errors in the response time detection of the perimeter intrusion alarm system, the battery can be kept to continuously supply power to the simulated intrusion component 303.

[0056] In this way, when the control room of the enclosure intrusion alarm system is far away from the enclosure, there is no need to power the first timekeeping component 301 and the second timekeeping component 302 through a long-distance line, which is not only convenient for real-time implementation of the solution, but also convenient for carrying.

[0057] In some optional implementations of this embodiment, the second processor 3033 can control the battery to supply power to the simulated intrusion component 303 while generating the control instruction. This avoids setting up an additional power supply for the simulated intrusion component 303, and does not need to connect any external power cables, thereby solving the problem of difficulty in obtaining power during on-site detection, facilitating use and transportation, and improving the convenience of implementing this solution.

[0058] In some optional implementations of this embodiment, the simulated intrusion component 303 may include a control component and a mechanical arm. The control component is used to control the mechanical arm to hit the enclosure when receiving a control instruction. In some specific practices, the simulated intrusion component 303 may be a pop-up device controlled by an electromagnetic switch.

[0059] In some optional implementations of this embodiment, the computing component 304 can communicate with the first timekeeping component 301 and the second timekeeping component 302 in a wireless manner. Specifically, the computing component 304, the first timekeeping component 301, and the second timekeeping component 302 can be provided with a wireless communication module to implement wireless communication. The wireless method can be 4G wireless communication.

[0060] In some optional implementations of this embodiment, the start time of the simulated intrusion behavior can also be set by the user through the interface. In the present disclosure, the start time set by the user can be recorded as the target start time. In this case, the calculation component 304 can directly send the above target start time to the second timekeeping component 302, or forward the above target start time to the second timekeeping component 302 through the first timekeeping component 301.

[0061] In some optional implementations of this embodiment, the frequency pulse signals generated by the first timekeeping module 3012 and the second timekeeping module 3022 have the same period, which is nanoseconds or picoseconds, that is, the first preset duration is equal to the second preset duration.

[0062] See also Figure 4 , which shows an application scenario of the detection device of the alarm response time of the perimeter intrusion alarm system disclosed in the present invention. In this application scenario, the computing component of the detection device is set in a computer device and exists in the form of detection software. The perimeter intrusion alarm system can also be installed in the computer device, and a communication interface for communicating with the first timekeeping component can also be set.

[0063] The first timekeeping component of the detection device may include a battery, a first processor, a first satellite navigation data receiving module, a first timekeeping module, a communication interface for wired communication with the computing component, and a wireless communication module. The first timekeeping component may be arranged outdoors.

[0064] The second timekeeping component of the detection device may include a battery, a second processor, a second satellite navigation data receiving module, a second timekeeping module, a wireless communication module for wirelessly communicating with the wireless communication module in the first timekeeping component, and a communication interface for wired communication with the simulated intrusion component. The second timekeeping component may be arranged in an area close to the simulated intrusion component.

[0065] Place the simulated intrusion component near the perimeter, and ensure that its mechanical arm can hit the perimeter after being released. Then connect the second timing component to the simulated intrusion component and to the battery of the second timing component. Connect the first timing component to the computing component and the software of the perimeter intrusion alarm system through the communication interface. Here, the computing component is embodied as the detection and recording software installed on the computer.

[0066] Connect the battery of the first timekeeping component. Set the output pulse frequency of the first timekeeping module and the second timekeeping module, and also set the clock frequency of the first processor and the second processor. Here, the output pulse frequency of the first timekeeping module and the second timekeeping module can be set to the same frequency, and the clock frequency of the first processor and the second processor can be set to the same frequency. Then, set the start time of the simulated intrusion behavior. Specifically, the start time can be set through the operation interface of the detection and recording software. The start time is recorded as t0, and the time format is: year: month: day: hour: minute: second: millisecond. Then, the start time is sent to the second timekeeping component through the first timekeeping component via 4G wireless transmission.

[0067] The first timekeeping component and the second timekeeping component can receive the GNSS signal of the satellite navigation system, and parse it to obtain the UTC time. The UTC time is timed to obtain the first timekeeping time and the second timekeeping time. When the second timekeeping component determines that the second timekeeping time it obtains is consistent with the start time, it sends a control instruction to the simulated intrusion component, and the simulated intrusion component releases the mechanical arm to hit the perimeter. The perimeter intrusion alarm system outputs an alarm message. The detection and recording software records the first timekeeping time when the alarm message is output, recorded as t1, and the time format is: year: month: day: hour: minute: second: millisecond. Calculate the alarm response time Δt=t1-t0, the time format is: year: month: day: hour: minute: second: millisecond.

[0068] Since the onboard atomic clock of the satellite navigation system is extremely accurate, such as the onboard hydrogen atomic clock of my country's Beidou-3 global satellite navigation system, which has a daily stability of the E-15 order and a timing accuracy better than 20 nanoseconds, the first timekeeping component and the second timekeeping component of this embodiment both use satellite time as a reference for timekeeping, and the period of each timekeeping is controlled within 1 second. The frequency pulse signals used for timekeeping by the two have the same frequency, the period of the frequency pulse signal is in the nanosecond or picosecond level, and the main frequency of the first processor and the second processor is the same (that is, the single instruction cycle is the same), so the clock synchronization error of the first timekeeping component and the second timekeeping component is greatly reduced, and the timekeeping accuracy is improved.

[0069] The above-mentioned embodiments of the present disclosure provide a detection device for the alarm response time of a perimeter intrusion alarm system, which improves the timekeeping accuracy, greatly reduces the error of the alarm response time of the perimeter intrusion alarm system, and can realize long-distance and wireless detection.

[0070] Continue to see Figure 5 , which shows a flow chart of an embodiment of a method for detecting alarm response time of a perimeter intrusion alarm system according to the present disclosure. Figure 5 As shown, the method in this embodiment may include the following steps:

[0071] Step 501, control the first timekeeping component to receive and analyze the radio signal output by the satellite navigation system, and keep time for the obtained world standard time to obtain a first timekeeping time.

[0072] Step 502, control the second timing component to receive and parse the radio signal output by the satellite navigation system, and keep time for the obtained world standard time, and compare the obtained second timing time with the preset start time. In response to determining that the second timing time is consistent with the preset start time, send a control instruction to the simulated intrusion component.

[0073] Step 503, when receiving the control instruction, the simulated intrusion component is controlled to initiate a simulated intrusion behavior toward the perimeter, so that the perimeter intrusion alarm system issues an alarm based on the simulated intrusion behavior.

[0074] Step 504, the control calculation component determines the alarm time of the perimeter intrusion alarm system according to the first timekeeping time; and determines the alarm response time of the perimeter intrusion alarm system according to the preset start time and the alarm time.

[0075] The method for outputting information provided by the above-mentioned embodiments of the present disclosure can respectively perform high-precision timekeeping at the perimeter end and the alarm end of the perimeter intrusion alarm system by using the UTC time and nanosecond or picosecond pulse frequency signals output by the highly accurate satellite navigation system onboard atomic clock, thereby greatly reducing the detection error of the alarm response time of the perimeter intrusion alarm system, improving the accuracy of the detection time, and realizing long-distance, wireless detection.

[0076] In some optional implementations of this embodiment, the first timekeeping component includes: a first satellite navigation data receiving module, a first timekeeping module, a first processor and a first communication port. The above step 501 can be specifically implemented by the following steps:

[0077] Step 5011, control the first satellite navigation data receiving module to receive the radio signal of the satellite navigation system, and output a second pulse signal and a first time message to the first processor according to the radio signal.

[0078] Step 5012: Control the first timekeeping module to generate a first frequency pulse signal with a period of a first preset time length, and send the first frequency pulse signal to the first processor.

[0079] Step 5013, controlling the first processor to determine the first punctual time according to the second pulse signal, the first time message and the first frequency pulse signal.

[0080] Step 5014, controlling the first communication port to send the first timekeeping time to the computing component.

[0081] In some optional implementations of this embodiment, the above-mentioned step 5013 can be further implemented through the following steps: controlling the first processor to parse the first time message at the rising edge of the second pulse signal to determine the world standard time; determining the first punctual time according to the world standard time and the first frequency pulse signal.

[0082] In some optional implementations of this embodiment, the above-mentioned step 5013 can be further implemented by the following steps: at the rising edge of the first frequency pulse signal, continuously counting the number of received first frequency pulses; determining the first punctual time based on the number, the first preset period and the world standard time.

[0083] In some optional implementations of this embodiment, the second timekeeping component includes: a second satellite navigation data receiving module, a second timekeeping module, a second processor and a second communication port. The above step 502 can be implemented by the following steps:

[0084] Step 5021, controlling the second satellite navigation data receiving module to receive the radio signal of the satellite navigation system, and outputting a second pulse signal and a second time message to the second processor according to the radio signal.

[0085] Step 5022: Control the second timekeeping module to generate a second frequency pulse signal with a period of a second preset time length, and send the second frequency pulse signal to the second processor.

[0086] Step 5023, control the second processor to determine the second timekeeping time according to the second pulse signal, the second time message and the second frequency pulse signal; and generate a control instruction when the second timekeeping time is consistent with the preset start time.
