[ detailed description ] embodiments
Fig. 1 is a schematic diagram of an environment monitoring system according to an embodiment. Referring to fig. 1, the environment monitoring system 10 includes one or more status sensors 120, a control device 140, and one or more portable information capturing devices 160. The control device 140 is coupled to each of the status sensors 120. For convenience of explanation, the following is an example of a portable information acquisition device 160, but this number is not a limitation of the present invention.
Fig. 2 is a functional block diagram of an example of the control device 140 of fig. 1. In some embodiments, referring to fig. 1 and 2, the control device 140 at least includes a processing unit 141, a storage unit 143, a wireless transmission module 145 and a signal input interface 147. The processing unit 141 is coupled to the storage unit 143, the wireless transmission module 144 and the signal input interface 147, and the signal input interface 147 is coupled to each of the status sensors 120. Here, the wireless transmission module 145 supports a short range wireless transmission technology.
Fig. 3 is a functional block diagram of an example of the portable information acquisition device 160 of fig. 1. In some embodiments, referring to fig. 1 and 3, the portable information capturing device 160 at least includes a processing unit 161, a storage unit 163, a wireless transmission module 165, and an information capturing module 167. The processing unit 161 is coupled to the storage unit 163, the wireless transmission module 165 and the information retrieving module 167. Here, the wireless transmission module 165 supports a short-range wireless transmission technology.
Fig. 4 is a schematic diagram of an implementation state of the environment monitoring system of fig. 1. In some embodiments, referring to fig. 1 and 4, each status sensor 120 and control device 140 are fixedly mounted on a mobile carrier 100. The portable information-capturing device 160 is movably disposed on a user of the mobile vehicle 100, such as a driver or a passenger. In some embodiments, the portable information-capturing device 160 can be worn on any part of the user (e.g., head, chest, etc.), and can be moved along with the user in a handheld manner, but the invention is not limited thereto.
Fig. 5 is a flowchart illustrating a driving method of the portable information acquisition device according to an embodiment. Referring to fig. 1 to 5, the state sensor 120 can sense an environmental state to generate at least one sensing signal (step S510). In some embodiments, each status sensor 120 can be an alarm device 102, an engine thermal sensing device connected to an engine of the mobile vehicle 100, an impact sensing device connected to the vehicle bodies 104, 106 of the mobile vehicle 100, an automobile burglar alarm of the mobile vehicle 100, or an emergency braking system of the mobile vehicle 100. For example, alarm device 102 activates its alarm to sound, and simultaneously generates a sensing signal to control device 140. Alternatively, when the engine thermal sensing device senses that the engine of the mobile vehicle 100 is overheated, the engine thermal sensing device not only sends an overheating alarm to the main control device of the mobile vehicle 100, but also generates a sensing signal to the control device 140. Alternatively, when the impact sensing device senses the impact of the mobile vehicle 100, it not only sends an impact warning to the main control device of the mobile vehicle 100, but also generates a sensing signal to the control device 140. Alternatively, when the car alarm senses an abnormal intrusion of the mobile vehicle 100, the car alarm activates the car alarm to sound, and simultaneously generates a sensing signal to the control device 140. Alternatively, the emergency braking system of mobile vehicle 100 generates a sensing signal to control device 140 when the emergency braking starts.
The processing unit 141 of the control device 140 receives the sensing signal through the signal input interface 147 and controls the wireless transmission module 145 to transmit a broadcast packet according to the sensing signal (step S520). Here, the wireless transmission module 145 sends out the broadcast packet in a broadcast manner. The broadcast packet includes broadcast data, and the broadcast data includes a start command. Here, the broadcast data may be preset and stored in the storage unit 143 of the control device 140.
The wireless transmission module 165 of the portable information acquisition device 160 scans/detects wireless signals within the effective service range. The portable information capturing device 160 is in the effective service range of the wireless transmission module 145, and the wireless transmission module 165 receives the broadcast packet from the control device 140 (step S530).
When the wireless transmission module 165 receives the broadcast packet from the control device 140, the processing unit 161 of the portable information capturing device 160 compares a matching data with the broadcast data in the received broadcast packet (step S540) to determine whether the matching data matches the broadcast data (step S542). Here, the matching data is preset and stored in the storage unit 163. After receiving the broadcast packet, the processing unit 161 reads the matching data from the storage unit 163 and compares the matching data.
In some embodiments, the broadcast data includes a basic data in addition to the start command. Here, the processing unit 161 compares the matching data with the basic data in the received broadcast packet to confirm whether the two match.
When the matching data matches the broadcast data (e.g., the basic data matches the matching data), the processing unit 161 of the portable information capturing device 160 starts the information capturing module 167 to execute the media capturing procedure based on the start instruction in the received broadcast packet (step S550). During the execution of the media capturing program, the information capturing module 167 records images and/or sounds of the surrounding environment to generate a media file, and the processing unit 161 stores the media file generated by the information capturing module 167 in the processing unit 161.
On the contrary, if the matching data does not match the broadcast data (e.g., the basic data does not match the matching data), the processing unit 161 of the portable information capturing device 160 does not start the information capturing module 167 to execute the media capturing procedure based on the start command in the received broadcast packet (step S560).
In one embodiment, the processing unit 141 of the control device 140 controls the wireless transmission module 145 to send the broadcast packet in response to the sensing signal after receiving the sensing signal.
In another embodiment, when receiving a sensing signal, the processing unit 141 of the control device 140 may first determine whether the sensing signal corresponds to the constraint condition. When the sensing signal does not meet the corresponding limitation condition, the processing unit 141 controls the wireless transmission module 145 to transmit the broadcast packet. Otherwise, the processing unit 141 does not control the wireless transmission module 145 to send the broadcast packet. Here, for different state sensors 120, the storage unit 163 is preset and stores the restriction conditions corresponding to the sensing signals. For example, assuming the state sensor 120 is an engine thermal sensor, the engine thermal sensor transmits the current temperature (sensing signal) of the engine to the processing unit 141 of the control device 140. The processing unit 141 reads out a temperature threshold (limiting condition) corresponding to the current temperature of the engine from the storage unit 163, and confirms whether the current temperature is lower than the temperature threshold (limiting condition). When the current temperature is not lower than the temperature threshold (not meeting the limit condition), the processing unit 141 controls the wireless transmission module 145 to transmit the broadcast packet.
Fig. 6 is a flowchart illustrating a driving method of a portable information acquisition device according to another embodiment. In some embodiments, the portable information capturing device 160 can be in a low power consumption state such as an off state or a sleep state. For example, in a normal state, most components of the portable information acquisition device 160 are powered off, and only the power required for the operation of the wireless transmission module 165 is supplied. Referring to fig. 1 to 4 and fig. 6, before sending the broadcast packet, the processing unit 141 controls the wireless transmission module 145 to send a wake-up signal (step S522) to wake up the portable information acquisition device 160 in the sleep state. After sending the wake-up signal (step S522), the processing unit 141 controls the wireless transmission module 145 to send the broadcast packet (step S524). In other words, after the wireless transmission module 165 of the portable information acquisition device 160 receives the wake-up signal, it responds to the wake-up signal to wake up the entire portable information acquisition device 160.
In an embodiment, the processing unit 141 of the control device 140 controls the wireless transmission module 145 to send the wake-up signal in response to the sensing signal after receiving the sensing signal. After the wake-up signal is sent, the processing unit 141 controls the wireless transmission module 145 to send the broadcast packet.
In another embodiment, when receiving a sensing signal, the processing unit 141 of the control device 140 may first determine whether the sensing signal corresponds to the constraint condition. When the sensing signal does not meet the corresponding limit condition, the processing unit 141 controls the wireless transmission module 145 to send a wake-up signal. After the wake-up signal is sent, the processing unit 141 controls the wireless transmission module 145 to send the broadcast packet. Otherwise, the processing unit 141 does not control the wireless transmission module 145 to send the wake-up signal and the broadcast packet. Alternatively, when receiving the sensing signal, the processing unit 141 first controls the wireless transmission module 145 to send the wake-up signal and determines whether the corresponding limitation condition is satisfied. If the determination is positive, the processing unit 141 controls the wireless transmission module 145 to send the broadcast packet. If the determination is not satisfied, the processing unit 141 does not control the wireless transmission module 145 to send the broadcast packet. Here, for different state sensors 120, the storage unit 163 is preset and stores the restriction conditions corresponding to the sensing signals.
In some embodiments, the control device 140 and the portable information-capturing device 160 may respectively have another wireless transmission module (not shown) for supporting large data transmission. The other wireless transmission module of the control device 140 can establish a communication link with the other wireless transmission module of the portable information acquisition device 160, so that the portable information acquisition device 160 can upload the stored media file to the control device 140 or to a server (not shown) via the control device 140. Here, the other wireless transmission module of the control device 140 can also support the long-range wireless transmission technology, so that the control device 140 can establish a communication link with the server by using the other wireless transmission module. Alternatively, the control device 140 may further have a communication module, and the control device 140 establishes a communication link with the server by using the communication module.
In some embodiments, the portable information capturing device 160 can be a multimedia capturing device such as a camcorder (body word camera), a walkman, a recording pen, or a driving recorder.
In some embodiments, each processing unit (141 or 161) may be implemented by one or more processing elements. The Processing elements may be soc (system on a chip) chips, Central Processing Units (CPUs), Microcontrollers (MCUs), etc., but the invention is not limited thereto.
In some embodiments, each storage unit (143 or 163) may be implemented by one or more storage elements. Each storage element may be a non-volatile memory, such as a Read Only Memory (ROM) or a Flash memory, or a volatile memory, such as a Random Access Memory (RAM).
In some embodiments, the wireless transmission module 145 and the wireless transmission module 165 may be Bluetooth transmission modules that use Bluetooth (Bluetooth) communication protocols, such as Bluetooth High Speed (Bluetooth High Speed) or Bluetooth Low Energy (BLE), for data transmission. Here, the broadcast packet may be a bluetooth broadcast packet. The wake-up signal may also be a bluetooth broadcast packet.
In some embodiments, the signal input interface 147 may be a signal connection port.
In some embodiments, the media file includes multimedia data recorded with images and/or sounds. In another embodiment, the media file includes the data name, data type, data setting information, etc. of the multimedia data in addition to the multimedia data recorded with image and/or sound.
In some embodiments, the mobile vehicle 100 may be a vehicle such as a locomotive, an automobile, a truck, or a bus.
In some embodiments, the server may include one or more hosts, and each host may be an information processing device such as a computer or a server.
In summary, the environment monitoring system and the driving method of the portable information capturing device according to the present invention are suitable for immediately starting the portable information capturing device to capture media when the state occurs, and do not need to wait for manual start, so as to immediately and automatically record the environmental image and/or sound when the state occurs.
