Description

Technical Field

[0001] The invention relates to the field of monitoring, and in particular to a patrol system. Background Art

[0002] The patrol system is a system used to monitor whether patrol personnel perform their duties. The patrol system can record whether patrol personnel conduct patrol inspections at regular times and locations as required, making it easier for management personnel to manage patrol personnel.

[0003] The existing patrol system includes patrol sensors installed at the checkpoint, such as a time clock, and patrol devices carried by patrol personnel, such as patrol cards and patrol sticks. When the patrol personnel arrive at the checkpoint, they use the patrol device to approach the patrol sensor device for induction recognition. The patrol device records the time of induction and the identity code of the patrol sensor device to prove that the patrol personnel arrived at the checkpoint where the patrol sensor device is located at that time.

[0004] Since the existing patrol system requires the patrol personnel to manually bring the patroller close to the patrol sensor device for sensing after arriving at the checkpoint, that is, the existing patroller cannot automatically sense the patrol sensor device. Therefore, when the patrol personnel are busy patrolling or checking equipment and ignore using the patroller to sense the patrol sensor device, they are likely to miss the patrol time, resulting in erroneous absenteeism and lateness records, which seriously affects the enthusiasm of the patrol personnel.

Therefore, the features defined as "first" and "second" may explicitly or implicitly include at least one of the features.

[0054] The content of the present invention will be described in detail below in conjunction with the accompanying drawings so that those skilled in the art can understand the content of the present invention in more detail.

[0055] like Figures 1 to 5 As shown, the present invention provides a patrol system, including a patrol sensor device 1000 arranged at a checkpoint and a patrol device 2000 carried by a patrol inspector, wherein the patrol sensor device 1000 includes a lighting lamp 1010, an intermittent oscillator 1020, a position compiler 1030 and a lighting driver 1040; wherein,

[0056] The input end of the intermittent oscillator 1020 is connected to the power supply, and the output end of the intermittent oscillator 1020 outputs a pulse signal to the position compiler 1030;

[0057] The input end of the position compiler 1030 is in communication connection with the intermittent oscillator 1020, and the output end of the position compiler 1030 provides a driving voltage with checkpoint coding information to the lighting driver 1040;

[0058] The input end of the lighting driver 1040 is connected to the position compiler 1030 for communication, and the output end of the lighting driver 1040 is connected to the lighting lamp 1010;

[0059] The lighting lamp 1010 emits a light signal carrying the checkpoint coding information;

[0060] The patroller 2000 is used to receive the optical signal and record the checkpoint coding information corresponding to the optical signal.

[0061] Since the lighting lamp 1010 in the patrol sensor device 1000 continuously emits a light signal carrying the checkpoint coding information 24 hours a day, when the patrol personnel approach the checkpoint, the patrol personnel do not need to touch the patrol sensor device 1000, and the patrol device 2000 can automatically sense the light signal carrying the checkpoint coding information. When the patrol device 2000 senses the light signal carrying the checkpoint coding information, it can be proved that the patrol personnel arrived at the checkpoint where the patrol sensor device 1000 is located at that time. Even if the patrol personnel are busy patrolling or checking equipment, they will not miss the patrol time, which is conducive to reducing the incidence of erroneous absenteeism records and erroneous late records, and can improve the enthusiasm of patrol personnel.

[0062] Specifically, the input end of the intermittent oscillator 1020 is connected to the power supply, and the output end of the intermittent oscillator 1020 outputs a pulse signal to the position compiler 1030. The pulse signal may be a square wave, and the period may be 10 ms.

[0063] The input end of the position compiler 1030 is in communication with the intermittent oscillator 1020. The position compiler 1030 edits the pulse signal from the intermittent oscillator 1020 so that the pulse signal carries the checkpoint coding information. The output end of the position compiler 1030 provides the lighting driver 1040 with a driving voltage with the checkpoint coding information.

[0064] The input end of the lighting driver 1040 is connected to the position compiler 1030 , and the lighting driver 1040 amplifies the driving voltage with the checkpoint coding information and converts it into the working voltage of the lighting lamp 1010 , and the working voltage carries the checkpoint coding information. The output end of the lighting driver 1040 is connected to the lighting lamp 1010 .

[0065] The lighting lamp 1010 emits a light signal carrying the checkpoint coding information. Since the intermittent oscillator 1020, the position compiler 1030 and the lighting driver 1040 can work 24 hours a day, the lighting lamp 1010 can continuously emit a light signal carrying the checkpoint coding information 24 hours a day. The period of the light signal is consistent with the period of the pulse signal output by the intermittent oscillator 1020, which can be 10ms, and the brightness of the light signal is low, which is not enough for the human eye to perceive the light.

[0066] The lighting lamp 1010 may be an LED lighting lamp 1010 , which is advantageous for the lighting driver 1040 to control the operating voltage of the lighting lamp 1010 so that the light signal emitted by the lighting lamp 1010 carries the checkpoint coding information.

[0067] The present technical solution adopts a patrol system including a patrol sensor device 1000 arranged at a checkpoint and a patroller 2000 carried by the patroller, wherein the patrol sensor device 1000 includes a lighting lamp 1010, an intermittent oscillator 1020, a position compiler 1030 and a lighting driver 1040; wherein the output end of the position compiler 1030 provides a driving voltage with checkpoint coding information to the lighting driver 1040, and the lighting lamp 1010 emits a light signal carrying the checkpoint coding information; the patroller 2000 is used to receive the light signal and record the checkpoint coding information corresponding to the light signal. Therefore, when the patroller approaches the checkpoint, the patroller 2000 can automatically sense the light signal carrying the checkpoint coding information without touching the patrol sensor device 1000. When the patroller 2000 senses the light signal carrying the checkpoint coding information, it can be proved that the patroller has arrived at the checkpoint where the patrol sensor device 1000 is located at that time. Even if the inspectors are busy patrolling or checking equipment, they will not miss the inspection time, which is conducive to reducing the incidence of erroneous absenteeism records and erroneous lateness records, and can improve the enthusiasm of inspectors.

[0068] like Figure 3 and Figure 4 As shown, optionally, the inspection sensing device 1000 of this embodiment further includes an oscillation controller 1050 , an input end of the oscillation controller 1050 is connected to a power source, and an output end of the oscillation controller 1050 is communicatively connected to the lighting driver 1040 .

[0069] The output end of the oscillation controller 1050 outputs a pulse signal to the lighting driver 1040. The pulse signal may be a square wave, and the period may be 10 ms, that is, the operating frequency of the oscillation controller 1050 may be 100 Hz. The pulse signal output by the intermittent oscillator 1020 to the lighting driver 1040 may cause the lighting lamp 1010 to emit a light signal that is imperceptible to the human eye, and the pulse signal output by the oscillation controller 1050 to the lighting driver 1040 may cause the lighting lamp 1010 to illuminate.

[0070] This technical solution is beneficial to the normal lighting of the lighting lamp 1010 because the inspection sensing device 1000 also includes an oscillation controller 1050, the input end of the oscillation controller 1050 is connected to the power supply, and the output end of the oscillation controller 1050 is communicatively connected to the lighting driver 1040.

[0071] like Figure 3 and Figure 4 As shown, optionally, a switch 1060 is connected between the oscillation controller 1050 and the lighting driver 1040 in this embodiment.

[0072] The switch 1060 is used to control the lighting function of the illuminating lamp 1010. When the environment is dim, the lighting function of the illuminating lamp 1010 can be turned on, and when the environment is bright, the lighting function of the illuminating lamp 1010 can be turned off, which is conducive to saving energy. Although the illuminating lamp 1010 of this embodiment emits a light signal carrying the checkpoint coding information 24 hours a day, the lighting function of the illuminating lamp 1010 can still be controlled by the switch 1060.

[0073] Since the present technical solution adopts the technical means of connecting the switch 1060 between the oscillation controller 1050 and the lighting driver 1040, the lighting function of the lighting lamp 1010 can be controlled to be turned on and off by the switch 1060, which is beneficial to saving electric energy.

[0074] like Figure 3 and Figure 4 As shown, optionally, a phase controller 1070 is provided between the oscillation controller 1050 and the intermittent oscillator 1020 of this embodiment.

[0075] Since the output frequencies of the oscillation controller 1050 and the intermittent oscillator 1020 are the same, both can be 100 Hz, it is only necessary to set a phase controller 1070 between the oscillation controller 1050 and the intermittent oscillator 1020 to ensure that the phases of the pulse signal output by the oscillation controller 1050 and the pulse signal output by the intermittent oscillator 1020 are different, thereby avoiding mutual interference between the light signal pulse signal received by the lighting driver 1040 and the lighting pulse signal.

[0076] Specifically, Figure 3 As shown, the phase controller 1070 receives the pulse signal from the oscillation controller 1050 and the pulse signal from the intermittent oscillator 1020, identifies the phase of the pulse signal from the oscillation controller 1050 and the phase of the pulse signal from the intermittent oscillator 1020, and can modulate the phase of the pulse signal from the intermittent oscillator 1020, thereby ensuring that there is a phase difference between the phase of the pulse signal from the oscillation controller 1050 and the phase of the pulse signal from the intermittent oscillator 1020.

[0077] Or, if Figure 4 As shown, the phase controller 1070 receives the pulse signal from the oscillation controller 1050 and the pulse signal from the intermittent oscillator 1020, identifies the phase of the pulse signal from the oscillation controller 1050 and the phase of the pulse signal from the intermittent oscillator 1020, and may also modulate the phase of the pulse signal from the oscillation controller 1050, thereby ensuring that there is a phase difference between the phase of the pulse signal from the oscillation controller 1050 and the phase of the pulse signal from the intermittent oscillator 1020.

[0078] Since the present technical solution adopts the technical means of providing a phase controller 1070 between the oscillation controller 1050 and the intermittent oscillator 1020, the phase of the pulse signal output by the oscillation controller 1050 can be different from that of the pulse signal output by the intermittent oscillator 1020, thereby avoiding mutual interference between the optical signal pulse signal and the lighting pulse signal received by the lighting driver 1040, which is beneficial for the lighting lamp 1010 to emit a light signal while lighting, thereby facilitating the normal operation of the patrol system.

[0079] like Figures 2 to 4 As shown, optionally, the inspection sensing device 1000 of this embodiment further includes a rectifier regulator 1080 , the input end of the rectifier regulator 1080 is connected to an AC power supply, and the rectifier regulator 1080 is used to supply power to the inspection sensing device 1000 .

[0080] Specifically, the rectifier regulator 1080 is directly connected to the 220V AC power supply, and can provide a 12V DC voltage for the inspection sensing device 1000. Through the electrical connection between the intermittent oscillator 1020, the position compiler 1030, and the lighting driver 1040 and the rectifier regulator 1080, the rectifier regulator 1080 will convert the 12V DC voltage to supply power to the intermittent oscillator 1020, the position compiler 1030, and the lighting driver 1040. Thus, it is conducive to the normal operation of the inspection sensing device 1000.

[0081] Since the present technical solution adopts the patrol sensing device 1000 which also includes a rectifier regulator 1080, the input end of the rectifier regulator 1080 is connected to the AC power supply. The rectifier regulator 1080 is a technical means for supplying power to the patrol sensing device 1000, providing a DC voltage for the patrol sensing device 1000, which is beneficial to the normal operation of the patrol sensing device 1000.

[0082] like Figure 5 As shown, optionally, the patrol device 2000 of this embodiment includes a photosensitive receiver 2010, a processor 2020 and an information storage 2030; wherein,

[0083] The input end of the processor 2020 is connected in communication with the photosensitive receiver 2010 , and the processor 2020 is used to process the optical signal with checkpoint coding information received by the photosensitive receiver 2010 ; the output end of the processor 2020 is connected in communication with the information storage 2030 .

[0084] When the inspector approaches the checkpoint, the patroller 2000 carried by him receives the light signal emitted by the illuminating lamp 1010. Since the illuminating lamp 1010 can emit light signals carrying the coded information of the checkpoint at all times, day and night, 24 hours a day, once the inspector approaches the checkpoint, the patroller 2000 carried by him can receive the light signal from the illuminating lamp 1010 through the photosensitive receiver 2010, without any other operation by the inspector, such as touching the clock in or pressing the switch. That is, the patroller 2000 can automatically sense the inspection sensing device 1000 set at the checkpoint. Even if the inspector is busy inspecting or checking equipment, he will not miss the inspection time, which reduces the incidence of false absenteeism and false late records, and is conducive to improving the enthusiasm of the inspectors.

[0085] Specifically, the photosensitive receiver 2010 can be used to receive the optical signal carrying the checkpoint coding information from the lighting lamp 1010, and the photosensitive receiver 2010 can filter out other optical signals that do not contain the checkpoint coding information.

[0086] The processor 2020 is connected to the photosensitive receiver 2010 in communication, and the processor 2020 can be used to process the optical signal carrying the checkpoint coding information received by the photosensitive receiver 2010, and extract the checkpoint coding information. In addition, the processor 2020 is connected to the information storage 2030 in communication, and the processor 2020 can transmit the collected checkpoint coding information and the collection time to the information storage 2030.

[0087] The information storage 2030 records the checkpoint encoding information and the collection time collected by the processor 2020.

[0088] The present technical solution adopts a patroller 2000 including a photosensitive receiver 2010, a processor 2020 and an information storage 2030; wherein, the input end of the processor 2020 is communicatively connected to the photosensitive receiver 2010, and the processor 2020 is used to process the optical signal with checkpoint coding information received by the photosensitive receiver 2010; and the output end of the processor 2020 is communicatively connected to the information storage 2030. Therefore, the patroller 2000 can automatically sense the patrol sensing device 1000 set at the checkpoint, and then the patroller 2000 can process and record the collected checkpoint coding information and the collection time. Even if the patrollers are busy patrolling or checking equipment, they will not miss the patrol time, thereby reducing the incidence of erroneous absenteeism and erroneous late records, which is conducive to improving the enthusiasm of the patrollers.

[0089] like Figure 5 As shown, optionally, the inspection device 2000 of this embodiment includes a buzzer 2040 and an indicator light 2050 , the buzzer 2040 is communicatively connected to the processor 2020 , and the indicator light 2050 is communicatively connected to the processor 2020 .

[0090] When the information storage 2030 receives new checkpoint coding information and the collection time corresponding to the checkpoint coding information, the information storage 2030 feeds back the information of successful collection to the processor 2020, and the processor 2020 commands the buzzer 2040 to make a buzzing sound. At the same time, the processor 2020 commands the indicator light 2050 to flash, so as to remind the inspection personnel that the new checkpoint coding information and the collection time corresponding to the checkpoint coding information have been successfully extracted.

[0091] Since the sound of the buzzer 2040 may be covered by the ambient noise, an indicator light 2050 is provided to help the inspector know that the new checkpoint code information and the collection time corresponding to the checkpoint code information have been successfully extracted. If the buzzer sound cannot be heard and the indicator light 2050 is not observed to flash, it means that the inspector 2000 may not have received the checkpoint code information of the inspector's checkpoint, and manual intervention is required, such as calling a maintenance phone or using other methods to record that the inspector has arrived at the inspection point.

[0092] This technical solution uses a patroller 2000 including a buzzer 2040 and an indicator light 2050, wherein the buzzer 2040 is communicatively connected to the processor 2020, and the indicator light 2050 is communicatively connected to the processor 2020. This facilitates patrollers to learn about new checkpoint coding information and the successful extraction of the collection time corresponding to the checkpoint coding information.

[0093] like Figure 5 As shown, optionally, the patroller 2000 of this embodiment includes a power supply system, and the power supply system includes a solar cell group 2060 .

[0094] The power supply system of the patroller 2000 includes a solar cell group 2060. The solar cell group 2060 can convert the received optical signal into electrical energy to supply power for the normal use of the patroller 2000. The light source for power generation can be an optical signal carrying the checkpoint coding information from the lighting lamp 1010, although the optical signal cannot be detected by the human eye. Therefore, there is no need to use the lighting function of the lighting lamp 1010. The lighting lamp 1010 that constantly emits optical signals carrying the checkpoint coding information can provide a light source for the solar cell group 2060, and the solar cell group 2060 can supply power to the patroller 2000 to ensure the normal use of the patroller 2000. The solar cell group 2060 can be a thin-film solar cell group 2060. The use of the solar cell group 2060 is not only beneficial to environmental protection, but also eliminates the need for patrol personnel to frequently replace batteries, which is beneficial to simplifying the maintenance of the patroller 2000. Furthermore, since the solar cell group 2060 can generate electricity using the optical signal carrying the checkpoint coding information, the power outage of the patroller 2000 can be basically avoided, which is beneficial to improving the reliability of the patroller 2000.

[0095] The power supply system of the patroller 2000 may also include a backup battery, which can continue to provide power for the normal use of the patroller 2000 when the solar cell group 2060 fails, thereby helping to improve the stability of the power supply system of the patroller 2000.

[0096] Since this technical solution adopts the technical means that the patrol device 2000 includes a power supply system, and the power supply system includes a solar cell group 2060, it is beneficial to environmental protection, simplifies the maintenance of the patrol device 2000, and improves the reliability of the patrol device 2000.

[0097] like Figure 5 As shown, optionally, the patroller 2000 of this embodiment includes a USB interface 2070 .

[0098] The USB interface 2070 can facilitate the management personnel to extract the inspection information in the information storage 2030 of the patrol inspector 2000. The USB interface 2070 is connected to the output end of the processor 2020, and the processor 2020 is connected to the information storage 2030. Through the USB interface 2070, the management personnel can quickly retrieve the inspection information in the information storage 2030 with the help of the processor 2020. The inspection information records when the patrol inspector arrives at a certain inspection point, which is helpful for the management personnel to manage the patrol inspectors.

[0099] Since the technical solution adopts the technical means that the patrol device 2000 includes the USB interface 2070, it is helpful for the management personnel to quickly obtain the patrol information in the patrol device 2000, and it is helpful for the management personnel to manage the patrol personnel.

[0100] Optionally, the inspection device 2000 of this embodiment is installed on a safety helmet.

[0101] Since inspectors are required to wear safety helmets when inspecting checkpoints at various factories, oil fields or construction sites, the inspector 2000 equipped on the safety helmet does not need to be carried separately by the inspectors, which reduces the extra burden on the inspectors and the probability of forgetting to carry the inspector 2000, providing convenience for the inspectors.

[0102] In addition, the indicator light 2050 can be installed on the inside of the brim, which is conducive to the inspection personnel to perceive the flashing of the indicator light 2050. The photosensitive receiver 2010 and the thin-film solar cell group 2060 can be installed on the outside of the helmet, which is conducive to the photosensitive receiver 2010 and the thin-film solar cell group 2060 receiving light signals.

[0103] Since this technical solution adopts the technical means of installing the inspection device 2000 on the safety helmet, it is helpful to reduce the extra burden of the inspection personnel, and also reduces the probability of the inspection personnel forgetting to carry the inspection device 2000, which provides convenience for the inspection personnel.

[0104] Embodiment 1

[0105] like Figure 2 As shown, in order to make the lighting lamp 1010 set up near the checkpoint continuously emit the light signal with the checkpoint coding information for 24 hours, the inspection sensor device 1000 includes the lighting lamp 1010, a rectifier regulator 1080, an intermittent oscillator 1020, a position compiler 1030 and a lighting driver 1040.

[0106] The rectifier regulator 1080 is directly connected to a 220V AC power source, and can provide a 12V DC voltage for the inspection sensor device 1000. Through the electrical connection between the intermittent oscillator 1020, the position compiler 1030, and the lighting driver 1040 and the rectifier regulator 1080, the rectifier regulator 1080 converts the 12V DC voltage to supply power to the intermittent oscillator 1020, the position compiler 1030, and the lighting driver 1040, respectively.

[0107] The input end of the intermittent oscillator 1020 is connected to the rectifier regulator 1080, and the output end of the intermittent oscillator 1020 outputs a pulse signal to the position compiler 1030. The pulse signal may be a square wave, and the period may be 10 ms.

[0108] The input end of the position compiler 1030 is in communication with the intermittent oscillator 1020. The position compiler 1030 edits the pulse signal from the intermittent oscillator 1020 so that the pulse signal carries the checkpoint coding information. The output end of the position compiler 1030 provides the lighting driver 1040 with a driving voltage with the checkpoint coding information.

[0109] The input end of the lighting driver 1040 is connected to the position compiler 1030 , and the lighting driver 1040 amplifies the driving voltage with the checkpoint coding information and converts it into the working voltage of the lighting lamp 1010 , and the working voltage carries the checkpoint coding information. The output end of the lighting driver 1040 is connected to the lighting lamp 1010 .

[0110] The lighting lamp 1010 emits a light signal carrying the checkpoint coding information. Since the electrical connection between the intermittent oscillator 1020, the position compiler 1030, and the lighting driver 1040 and the rectifier regulator 1080 is uninterrupted, and the connection between the rectifier regulator 1080 and the 220V AC power supply is also uninterrupted, the lighting lamp 1010 can emit a light signal carrying the checkpoint coding information 24 hours a day. The period of the light signal is consistent with the period of the pulse signal output by the intermittent oscillator 1020, which can be 10ms, and the brightness of the light signal is low, which is not enough for the human eye to perceive the light. Figure 7 The voltage waveform provided by the lighting driver 1040 to the lighting lamp 1010 is shown. At this time, the lighting function of the lighting lamp 1010 is turned off, only the intermittent oscillator 1020 is working, the oscillation controller 1050 is not working, and the pulse signal emitted by the intermittent oscillator 1020 corresponds to the first voltage waveform 3100.

[0111] The lighting lamp 1010 may be an LED lighting lamp 1010 , which is advantageous for the lighting driver 1040 to control the operating voltage of the lighting lamp 1010 so that the light signal emitted by the lighting lamp 1010 carries the checkpoint coding information.

[0112] When the inspector approaches the checkpoint, the patrol device 2000 carried by him receives the light signal emitted by the lighting lamp 1010. Since the lighting lamp 1010 can emit light signals carrying the checkpoint coding information at all times, day and night, 24 hours a day, once the inspector approaches the checkpoint, the patrol device 2000 carried by him can receive the light signal from the lighting lamp 1010 without any other operation by the inspector, such as touching the clock in or pressing the switch. That is, the patrol device 2000 can automatically sense the inspection sensing device 1000 set at the checkpoint. Even if the inspector is busy inspecting or checking equipment, he will not miss the inspection time, reducing the incidence of false absenteeism and false late records, which is conducive to improving the enthusiasm of the inspectors.

[0113] like Figure 5 As shown, the patrol device 2000 carried by the patrol personnel includes a photosensitive receiver 2010, a processor 2020, an information storage 2030, a buzzer 2040, an indicator light 2050, a power system and a USB interface 2070.

[0114] The photosensitive receiver 2010 can be used to receive the optical signal carrying the checkpoint coding information from the lighting lamp 1010, and the photosensitive receiver 2010 can filter other optical signals that do not contain the checkpoint coding information.

[0115] The processor 2020 is connected to the photosensitive receiver 2010 in communication, and the processor 2020 can be used to process the optical signal carrying the checkpoint coding information received by the photosensitive receiver 2010, and extract the checkpoint coding information. In addition, the processor 2020 is connected to the information storage 2030 in communication, and the processor 2020 can transmit the collected checkpoint coding information and the collection time to the information storage 2030.

[0116] The information storage 2030 records the checkpoint encoding information and the collection time collected by the processor 2020.

[0117] When the information storage 2030 receives new checkpoint coding information and the collection time corresponding to the checkpoint coding information, the information storage 2030 feeds back the information of successful collection to the processor 2020, and the processor 2020 commands the buzzer 2040 to make a buzzing sound. At the same time, the processor 2020 commands the indicator light 2050 to flash, so as to remind the inspection personnel that the new checkpoint coding information and the collection time corresponding to the checkpoint coding information have been successfully extracted.

[0118] Since the sound of the buzzer 2040 may be covered by the ambient noise, an indicator light 2050 is provided to help the inspector know that the new checkpoint code information and the collection time corresponding to the checkpoint code information have been successfully extracted. If the buzzer sound cannot be heard and the indicator light 2050 is not observed to flash, it means that the inspector 2000 may not have received the checkpoint code information of the inspector's checkpoint, and manual intervention is required, such as calling a maintenance phone or using other methods to record that the inspector has arrived at the inspection point.

[0119] The power supply system of the patroller 2000 includes a solar cell group 2060. The solar cell group 2060 can convert the received optical signal into electrical energy to provide power for the normal use of the patroller 2000. The optical signal for power generation can be an optical signal carrying the checkpoint coding information from the lighting lamp 1010, although the optical signal cannot be detected by the human eye. Therefore, there is no need to use the lighting function of the lighting lamp 1010. The lighting lamp 1010 that constantly emits optical signals carrying the checkpoint coding information can provide a light source for the solar cell group 2060, and the solar cell group 2060 can supply power to the patroller 2000 to ensure the normal use of the patroller 2000. The solar cell group 2060 can be a thin-film solar cell group 2060.

[0120] The power supply system of the patroller 2000 may also include a backup battery, which can continue to provide power for the normal use of the patroller 2000 when the solar cell group 2060 fails, thereby helping to improve the stability of the power supply system of the patroller 2000.

[0121] The patroller 2000 also includes a USB interface 2070, which can facilitate the management personnel to extract the patrol information in the information storage 2030 of the patroller 2000. The USB interface 2070 is connected to the output end of the processor 2020, and the processor 2020 is connected to the information storage 2030. Through the USB interface 2070, the management personnel can retrieve the patrol information in the information storage 2030 with the help of the processor 2020. The patrol information records when the patrol personnel arrives at a certain inspection point, which is helpful for the management personnel to manage the patrol personnel.

[0122] The above-mentioned patrol device 2000 can be installed on a safety helmet. Since patrol personnel are required to wear safety helmets when inspecting checkpoints in various factories, oil fields or construction sites, the patrol device 2000 equipped on the safety helmet does not need to be carried separately by the patrol personnel, which reduces the extra burden on the patrol personnel and the probability of forgetting to carry the patrol device 2000, providing convenience for the patrol personnel.

[0123] The indicator light 2050 can be installed on the inside of the brim, which is beneficial for the inspector to perceive the flashing of the indicator light 2050. The photosensitive receiver 2010 and the thin-film solar cell group 2060 can be installed on the outside of the helmet, which is beneficial for the photosensitive receiver 2010 and the thin-film solar cell group 2060 to receive light signals.

[0124] Embodiment 2

[0125] like Figure 3 and Figure 4As shown, in order to enable the lighting lamp 1010 installed near the checkpoint to continuously emit the light signal carrying the checkpoint coding information without affecting the normal lighting function of the lighting lamp 1010, an oscillation controller 1050, a phase controller 1070 and a switch 1060 are also provided in the inspection sensing device 1000.

[0126] The input end of the oscillation controller 1050 is connected to the rectifier regulator 1080, and the output end of the oscillation controller 1050 outputs a pulse signal to the lighting driver 1040. The pulse signal may be a square wave with a period of 10 ms, that is, the operating frequency of the oscillation controller 1050 is 100 Hz.

[0127] Since the output frequency of the oscillation controller 1050 and the intermittent oscillator 1020 is the same, in order to ensure that the phase of the pulse signal output by the oscillation controller 1050 is different from that of the pulse signal output by the intermittent oscillator 1020, it is only necessary to set a phase controller 1070 between the oscillation controller 1050 and the intermittent oscillator 1020.

[0128] like Figure 3 As shown, the phase controller 1070 receives the pulse signal from the oscillation controller 1050 and the pulse signal from the intermittent oscillator 1020, identifies the phase of the pulse signal from the oscillation controller 1050 and the phase of the pulse signal from the intermittent oscillator 1020, and can modulate the phase of the pulse signal from the intermittent oscillator 1020, thereby ensuring that there is a phase difference between the phase of the pulse signal from the oscillation controller 1050 and the phase of the pulse signal from the intermittent oscillator 1020.

[0129] Or, if Figure 4 As shown, the phase controller 1070 receives the pulse signal from the oscillation controller 1050 and the pulse signal from the intermittent oscillator 1020, identifies the phase of the pulse signal from the oscillation controller 1050 and the phase of the pulse signal from the intermittent oscillator 1020, and may also modulate the phase of the pulse signal from the oscillation controller 1050, thereby ensuring that there is a phase difference between the phase of the pulse signal from the oscillation controller 1050 and the phase of the pulse signal from the intermittent oscillator 1020.

[0130] In order to control the on and off of the lighting function of the lighting lamp 1010, a switch 1060 is provided between the oscillation controller 1050 and the lighting driver 1040. By closing or opening the switch 1060, the output end of the oscillation controller 1050 is connected or disconnected with the lighting driver 1040.

[0131] The switch 1060 can be installed on a wall near a checkpoint, which helps inspection personnel to quickly locate the switch 1060 in a dark environment.

[0132] When the inspector arrives at the inspection point, if the environment is dark and needs to use the illuminating lamp 1010 for lighting, the inspector only needs to press the switch 1060, and the illuminating lamp 1010 can play its lighting function. Figure 6 The voltage waveform provided by the lighting driver to the lighting lamp is shown. The intermittent oscillator 1020 and the oscillation controller 1050 work simultaneously. The pulse signal emitted by the intermittent oscillator 1020 corresponds to the first voltage waveform 3100 , and the pulse signal emitted by the oscillation controller 1050 corresponds to the second voltage waveform 3200 .

[0133] And, if Figure 6 As shown, the lighting lamp 1010 can emit a light signal carrying the checkpoint coding information while illuminating normally. Figure 6 As shown, the illumination light and the optical signal of the same frequency maintain a phase difference, that is, the second voltage waveform 3200 maintains a phase difference with the first voltage waveform 3100. Since the second voltage waveform 3200 corresponds to the illumination light and the first voltage waveform 3100 corresponds to the optical signal, the illumination light and the optical signal do not interfere with each other.

[0134] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the aforementioned embodiments, or replace some or all of the technical features therein with equivalents. However, these modifications or replacements do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of the present invention.
