Detailed Description
The present invention will now be described more fully with reference to the accompanying drawings, in which exemplary embodiments of the invention are shown. This invention may, however, be embodied in many different forms and should not be construed as limited to the embodiments set forth herein. Rather, these embodiments are provided so that this disclosure will be thorough and complete, and will fully convey the concept of the invention to those skilled in the art.
Some of the block diagrams shown in the figures are functional entities and do not necessarily correspond to physically or logically separate entities. These functional entities may be implemented in software or in one or more hardware modules or integrated circuits or in different processing means and/or microcontroller means.
Fig. 1 is a schematic diagram of a system for determining physical location information of a field device in accordance with an embodiment of the present invention, the system 10 of which includes the field device 110 of the embodiment shown in fig. 2 and the mobile terminal 120 of the embodiment shown in fig. 3, and is further provided with a control center 130.
In this embodiment, the system 10 is specifically illustrated as a fire detection and alarm (D & a) system within a building, it being understood that the system 10 may also be embodied in other system configurations similar to the D & a system, for example, to systems requiring the installation of corresponding field terminals at a number of field physical location points and the ability of those terminals to interact with a control center; the particular application scenario of system 10 is also not limiting and may even be applied in an off-building environment, for example.
As shown in fig. 1, the control center 130 may be a center of the D & a system, which may be implemented by, for example, one or more computer servers, which may be centrally located at a location convenient for a manager to set up and operate, but, in still another embodiment, may be implemented by a plurality of computer devices to be located at a plurality of locations in a decentralized manner. Typically, the control center 130 may be located at a management center of a building (e.g., a building). The control center 130 has a communication module 132 for communication connection with each mobile terminal 120 to enable data transmission therebetween.
Continuing to refer to FIGS. 1 and 2, the field device 110 includes a field device 110 1 、110 2 、…、110 n N total, the specific number of field devices 110 is not limiting, D&The number is typically large in the a system; the field devices 110 are installed at various physical location points within the building to enable detection, monitoring, or otherwise enable feedback information to be entered from the various physical location points. The field devices 110 may be probes, manual alarms, etc. that may monitor various information acquired from physical location points of the field, and/or may transmit information to physical location points of the field, and/or may acquire manual input feedback from physical location points of the field, etc., the particular type of field device 110 is not limiting, and may choose to install different types of field devices 110 depending on the particular functional needs of the system 110, the requirements of the particular physical location points, etc. Also, at one physical location point, it is possible to provide a plurality of different kinds of field devices 110.
Each field device 110 is coupled to the control center 130, for example, by a wired connection to the control center 130 via a bus 131 or the like, and each field device 110 may be assigned a corresponding logical address by the control center 130 to facilitate management thereof, but the control center 130 also needs to obtain physical location information (i.e., a physical address) of each field device 110 to implement the corresponding function of the D & a system 10. Thus, during installation of each field device 110, the control center 130 is required to simultaneously prepare to determine the physical location information of the field device 110 so that control processing can be performed based on the physical location information during subsequent operations of the D & a system 10.
It should be understood that the physical location information may be actual planar location information reflecting the fixed installation of the field device 110, or may be actual spatial location information reflecting the fixed installation of the field device 110, in a form that can be identified by the control center 130, and the specific form of representation is not limited, and may be represented, for example, as "room×" or the like.
Each field device 110 typically has identification number (ID) information representing its uniqueness, e.g., each field device 110 is typically configured with a serial number at the factory, which can be used as its ID information in the system to determine the physical location information of the field device 110. In other embodiments, the user of field device 110 may additionally assign each field device corresponding ID information.
In this embodiment, during installation of each field device 110, the control center 130 may read the serial number stored in the field device 110 via the bus 131 and assign it a corresponding logical address, and thus, the control center 130 may have all the serial numbers of the field devices 110 coupled thereto, or have a logical address corresponding to the serial number of the field device 110.
Each field device 110 also has a status display light 111, and in the embodiment shown in fig. 2, the status display light 111 may be an LED status light, and the flashing process of turning on or off the status display light is controlled by a driving module 112, where the driving module 112 may be implemented, for example, but not limited to, by a chip (e.g., a CPU) or a circuit board, etc., which is mounted inside the field device 110 and may obtain at least a serial number of the field device 110, for example, status information, configuration information, etc. of the field device 110. The drive module 110 controls the blinking state 113 of its LED status light 111 based at least on the corresponding serial number of the field device 110, the specific control principle of which will be described in detail below. Accordingly, the flashing status 113 emitted by the LED status light 111 includes corresponding serial number information, and the serial number of the field device 110 is propagated by flashing the LED status light 111. In an embodiment, the control center 130 may also obtain the serial number, status information, configuration information, and/or the like from the drive module 112.
As further shown in fig. 1 and 3, the system 10 also includes a mobile terminal 120, which mobile terminal 120 may be one or more that are used by a worker during installation (or replacement installation) of the field device 110, the mobile terminal 120 being proximate to the field device 110 to be able to receive a blinking state of the LED status light 111, e.g., directly bringing the mobile terminal 120 proximate to the LED status light 111 of the field device 110. The mobile terminal 120 may be, for example, a smart phone terminal with mobile communication function, but may be any other type of handheld mobile smart terminal.
In an embodiment, the mobile terminal 120 first has a sensor 111 as shown in fig. 1 and 3, and the sensor 111 may be, for example, an image sensor of the smart phone terminal itself, which captures a blinking state 113 emitted by the LED status light 111 for a period of time. The scintillation status 113 (e.g., video information including the scintillation status 113) obtained by the sensor 111 is sent to the conversion module 122 of the mobile terminal 120, and the conversion module 122 analyzes the scintillation status 113 in the video information and converts to obtain serial number information corresponding to the scintillation status 113, so as to implement field interaction between the mobile terminal 120 and the field device 110, i.e., field reads the serial number of the field device 110.
In one embodiment, the mobile terminal 120 is further provided with an input module 124 for inputting physical location information of the field device 110 to which the mobile terminal 120 is currently corresponding, for example, the field device 110 installed in the room 3301, and after the mobile terminal 120 senses the blinking state 113 sent by the field device 110, the operator manually inputs the physical location information "room 3301" from the input module 124 of the mobile terminal 120. In other embodiments, if the mobile terminal 120 is capable of automatically acquiring physical location information of the current location (e.g., based on GPS pinpointing), the input of the physical location information may also be automatically implemented.
In an embodiment, the mobile terminal 120 is further provided with an association module 125, where the association module 125 associates the input physical location information with the corresponding acquired serial numbers of the field devices 110, for example, the association module 125 may store the serial numbers of the plurality of field devices 110 and the input plurality of physical location information, each serial number corresponding to a physical location information. The mobile terminal 120 is also provided with a communication module or port that can transmit the serial number stored by the association module 125 and its corresponding physical location information to the control center 130. When the mobile terminal 120 is a smart phone terminal with a mobile communication function, the communication module 132 of the control center 130 may also be a GPS communication module, and the mobile terminal 120 may send the associated serial number and its physical location information to the control center 130 in real time on site. In yet another alternative embodiment, the mobile terminal 120 may also send a plurality of already-associated serial numbers and their physical location information to the control center 130 at a time, for example, after each worker detects a plurality of field devices 110, the mobile terminal 120 is connected to the communication module 132 of the control center 130 by wire or wirelessly, and all the serial numbers and their physical location information are sent or uploaded to the control center 130.
In an embodiment, as shown in fig. 3, the mobile terminal 120 is further provided with a display module 123 for displaying at least identification number information obtained by conversion, for example, "serial number×", so as to facilitate the reading confirmation of the staff.
It should be noted that, the conversion module 122, the display module 123, the input module 124, the association module 125 and the like in the mobile terminal 120 in the above embodiment may be implemented by APP software, so that when the APP software is installed on, for example, a smart phone terminal carried by a worker, the smart phone terminal is implemented as the mobile terminal in the embodiment of the present invention, and no additional mobile terminal is required to be set in the system 10, so that the hardware cost of the system 10 is not increased, and the system is easy to be accepted by the worker, and the on-site operation of the worker is convenient and simple.
It should be noted that the number of mobile terminals 120 in the system 10 is not limited, and may be, for example, a plurality of mobile terminals 120, and each of a plurality of staff members may hold one mobile terminal 120.
As further shown in fig. 1, the control center 130 may obtain the serial number of each field device 110 from the bus 131, as described above, and may obtain the serial number of each field device 110 and its associated corresponding physical location information from the mobile terminal 120, so that in one embodiment, the control center 130 matches the physical location information of the field device 110 based on the serial number of the field device 110 and determines the physical location information as the physical location information of the field device 110, so that the control center 130 may determine the physical location information of each field device 110 and associate the physical location information of each field device 110 with a logical address, and may operate based on their physical location information during subsequent operation of the system 10, such as locating a fire alarm location, etc.
The principle of operation of the system 10 of an embodiment of the present invention is described in further detail below in conjunction with fig. 4.
In one embodiment, the serial number is generally comprised of multiple bits of data, and the drive module 112 of the field device 110 is configured to convert each bit of data of the serial number into a form of a Morse code to control the blinking of the status display light 111; for example, each bin in the time coordinates shown in fig. 4 represents a unit time (determined based on the sampling rate of the sensor, the blinking frequency of the status display lamp 111, etc.) at which the sensor 121 captures each frame of image; if the data of the serial number is "1", the Morse code is a short and three long (in unit time of each cell), the driving module 112 may output a corresponding code based on the Morse code principle to control the status display lamp 111 to flash in the form of "on-off-on, if the data of the serial number is" 2", the Morse code is two short and three long, and the driving module 112 can output a corresponding code based on the Morse code principle to control the status display lamp 111 to flash in the form of" on-off-on-off. In this way, the status display lamps 111 can sequentially emit the blinking status 113 for indicating the serial number.
Accordingly, at the mobile terminal 120, it also performs a decoding process based on the Morse code principle of the above field device 110. As shown in fig. 4, the sensor 121 performs shooting sampling based on a corresponding sampling rule, so as to obtain a flicker image as shown in fig. 4; then, the video image is analyzed and processed through the conversion module 122, so that the flicker state of the video image is obtained; the corresponding Morse code will further be read out, each Morse code being converted into data representing a serial number, thus enabling a decoded read of the serial number propagated by the field device 110.
It should be noted that in the above embodiment, the field device 110 and the mobile terminal 120 interact based on the Morse code, and it should be understood that other coding rules may be applied between the two to perform interaction by analogy, so that the mobile terminal 120 can obtain at least the serial number information of the field device 110.
In yet another embodiment, during maintenance, for example to facilitate reading status information of the field device 110, interaction between the field device 110 and the mobile terminal 120 based on the status information may be accomplished by configuring the two. The status information refers to environmental status information of the physical location where the field device 110 senses and knows, such as CO concentration, field temperature, etc., and may be uniformly encoded as a certain form of code, such as a Morse code. The driving module 112 of the field device 110 is capable of acquiring status information at a certain moment and encoding it into a Morse code, and the driving module 112 further controls the flashing of the status display lamp 111 based on the status information (i.e. the corresponding Morse code) to emit a flashing status 113. Likewise, the mobile terminal 120 is further configured to acquire the status information of the field devices 110 by sensing the blinking status 113 of the status display lamps 111, for example, the conversion module 122 is further configured to convert the blinking status 113 of the status display lamps 111 into a Morse code and further convert the Morse code into status information capable of being displayed and read on the mobile terminal 120, and the status information can be displayed on a display screen of the mobile terminal 120, so that a worker can simply and accurately read out the status information of each field device 110, and can greatly expand the variety of the status information that the field devices can output through the status display lamps 111, instead of being limited to outputting the current few simple status information, and can also reduce the dependence on the voice broadcast output function of the status information.
In yet another embodiment, during maintenance testing, to facilitate obtaining configuration information of the field device 110 (e.g., the current power configuration information "high", "medium", "low" of the battery of the field device 110), interaction between the field device 110 and the mobile terminal 120 based on the configuration information may be implemented. The configuration information is physical configuration information reflecting the field device 110 itself, such as, for example, the power of a battery, whether a certain component is operating normally, the parameter configuration of a certain component, etc., and may be uniformly encoded into a certain form of code, such as, for example, a Morse code. Under trigger conditions, the driver module 112 of the field device 110 can acquire configuration information at a certain moment and encode the configuration information into a Morse code, and the driver module 112 further controls the flashing of the status display lamp 111 based on the configuration information (i.e., the corresponding Morse code) to emit the flashing status 113. Likewise, the mobile terminal 120 is further configured to obtain the configuration information of the field devices 110 by sensing the blinking state 113 of the status display lamp 111, for example, the conversion module 122 is further configured to convert the blinking state 113 of the status display lamp 111 into a Morse code and further into configuration information that can be read by the mobile terminal 120, and the configuration information can be displayed on the display screen of the mobile terminal 120, so that a worker can simply and accurately read the configuration information of each field device 110, for example, can know the battery status information of the field device 110 and whether the key components are normal, thereby greatly improving the maintenance detection efficiency of the field device.
When the field devices 110 implement a capability to communicate at least two of the serial number, status information, configuration information via the status display lights 111, they may be uniformly encoded to enable them to be uniformly identified and read at the mobile terminal.
It should be understood that the field device 110 and the mobile terminal 120 of the above embodiments are not limited to the Morse encoding or Morse decoding based on the Morse protocol illustrated in fig. 4, that is, are not limited to the transmission of the serial number information, the status information and/or the configuration information based on the Morse code, and may be encoded or decoded based on other protocols, such as a custom encoding protocol.
It should be noted that, in the system 10 of the above embodiment, the function of the driving module 112 of the field device 110 may also be implemented by software programming, and the LED status light 111 is usually already set in the field device 110, so that the hardware cost of the field device 110 may also be avoided from being increased. For the system 10, the field devices 110 and the mobile terminals 120 may be implemented by software configuration through existing field devices and smart phone terminals, respectively (but not limited to), without increasing the cost of the system 10, which may significantly reduce the cost of determining the physical location information of the field devices, especially in very large numbers of field devices, compared to existing systems requiring RFID, proprietary handheld terminals.
Fig. 5 is a flow chart of a method for determining physical location information of a field device in accordance with an embodiment of the present invention. The following is a description of the principles of operation of the system 10 and specific method processes for determining physical location information according to embodiments of the present invention, with reference to fig. 1-5.
First, in step S510, the status display lamp 111 of the field device 110 is driven by the driving module 112 to flash for a certain period of time, and the flash status 113 contains the corresponding ID information, so that the ID information of the field device 110 is transmitted through the flash of the status display lamp 111. This step may be accomplished during installation of field device 110 and the display of status display lamp 111 may be drive controlled based on the Morse code principle, for example, to operate in the display manner shown in fig. 4.
In step S520, the worker holds the mobile terminal 120 (e.g., the smart phone terminal of the worker) as shown in fig. 3, and causes the sensor 121 of the mobile terminal 120 to be aligned with the status display lamp 111 of the field device 110 to sense the blinking status 113 of the status display lamp 111 for a period of time. In this step, the mobile terminal 120 may perform image acquisition on the status display lamp 111 based on the corresponding sampling rule.
In step S530, the mobile terminal 120 performs analysis conversion based on the acquired image, and acquires corresponding ID information. Specifically, the scintillation state 113 shown in fig. 4 is sensed; then, the video image is analyzed and processed by the conversion module 122, so that the Morse code (as shown in fig. 4) corresponding to the flicker state 113 is read out, and each Morse code is converted into data representing the serial number, so that decoding and reading of the ID information propagated by the field device 110 are realized.
In this step S530, the acquired ID information may also be displayed on the mobile terminal 120 in real time, for example, "serial number×" so as to facilitate the reading confirmation of the staff.
In step S540, the physical location information is input from the mobile terminal 120. Specifically, the worker manually inputs the physical location of the field device 110 currently installed, e.g., the worker manually inputs the physical location information "room 3301" from the input module 124 of the mobile terminal 120.
Step S550, the physical location information is associated with the corresponding ID information and transmitted to the control center together. In this step, specifically, the association module 125 at the mobile terminal 120 associates the input (input in step S540) physical location information with the ID information of the field device 110 (acquired in step S530) that is correspondingly acquired, for example, the association module 125 may store the ID information of the plurality of field devices 110 and the input plurality of physical location information, each of which corresponds to one physical location information. After the mobile terminal 120 and the control center 130 are communicatively connected together, the stored ID information and its corresponding physical location information may be transmitted together to the control center 130.
In this step S550, the mobile terminal 120 may record and count the number of the corresponding field devices of the above steps S520 to S540 that have been completed, preventing missing confirmation of the physical location information of a certain field device 110.
In step S560, the control center 130 determines the physical location information of the field device 110. In this step, the control center 130 has ID information of each field device 110 acquired from the bus 131 on the one hand, and on the other hand, after acquiring ID information of each field device 110 and its associated corresponding physical location information sent from the mobile terminal 120, the control center 130 matches the physical location information of the field device 110 based on the ID information of the field device 110 and determines the physical location information as the physical location information of the field device 110, so that the control center 130 can determine the physical location information of each field device 110 and associate the physical location information and the logical address of each field device 110.
To this end, confirmation is effected with respect to the physical location information of one of the field devices 110. Repeating the above process may enable verification of the physical location information of each field device of system 10, and thus, control center 130 has physical location information of field device 110 corresponding to each logical address, and during subsequent operational operation of system 10, may perform operations based on their physical location information, such as locating physical location points of the field fire alarm input information and controlling other field device operations (e.g., sprinkler operations) of the corresponding physical location points, etc.
The above process of confirming the physical location information of the field device 110 is simple to operate, does not require the introduction of other expensive special equipment, and is easy to implement at low cost.
Fig. 6 is a flow chart of a method for reading status information/configuration information of a field device by a mobile terminal according to an embodiment of the invention. In this embodiment, after the field device 110 is installed and its physical location information is determined, status information, configuration information, etc. of the field device may also be read by the mobile terminal, as described below in connection with fig. 1-4 and 6.
Step S610, under a certain triggering condition, enabling the status display lamp 111 of the field device 110 to operate under the driving of the driving module 112 and flash for a certain time; the status of the status indicator 113 includes corresponding status information/configuration information, so that the status information/configuration information of the field device 110 is propagated out through the flashing of the status indicator light 111. This step may be accomplished during maintenance and inspection of field device 110, and the display of status indicator light 111 may be driven based on the Morse code principle, for example, to operate in the display manner shown in fig. 4.
In step S620, the worker holds the mobile terminal 120 (e.g., the smart phone terminal of the worker) as shown in fig. 3, and causes the sensor 121 of the mobile terminal 120 to be aligned with the status display lamp 111 of the field device 110 to sense, thereby sensing the blinking status of the status display lamp 111 for a period of time. In this step, the mobile terminal 120 may perform image acquisition on the status display lamp 111 based on the corresponding sampling rule.
In step S630, the mobile terminal 120 performs analysis conversion based on the acquired image, and obtains corresponding status information/configuration information. Specifically, the scintillation state 113 shown in fig. 4 is sensed; then, the video image is analyzed and processed by the conversion module 122, so that the corresponding Morse codes (as shown in fig. 4) are read out, and each Morse code is converted into data representing the status information/configuration information, thereby implementing decoding and reading of the status information/configuration information propagated by the field device 110.
It should be noted that, the status information refers to environmental status information of the field device 110 sensed and learned corresponding physical location thereof, such as CO concentration, field temperature, and the like; such status information may be uniformly encoded as some form of code, such as a Morse code. The configuration information is physical configuration information reflecting the field device 110 itself, such as the amount of power of a battery, whether a certain component is operating normally, the parameter configuration of a certain component, and the like; the configuration information may also be uniformly encoded as some form of code, such as a Morse code.
The obtained status information/configuration information and the like read in the above step S630 may be displayed on the mobile terminal 120, so that a worker may simply and accurately read the status information/configuration information of each field device 110, and may greatly expand the kinds of information that the field device may output through the status display lamp 111, instead of being limited to output the current few simple status information, so as to facilitate maintenance and detection of the field device.
