Background
The sewer is one of the urban public facilities, which has emerged in the ancient roman age. The collection mode of the sewer is two types, namely a confluence type sewer and a diversion type sewer. The mode that rain water and sewage of rainfall are collected by the same canal is called confluence sewer, and the canal is called confluence pipe. If the rainwater and the sewage are collected by respective pipes, they are called as a divided sewer, and the pipes are rainwater pipes and sewage pipes.
In Taiwan, due to the large rainfall, the inherent low flow of river and the lack of dilution capability, the adoption of a split-flow sewer is more commonly adopted. The sewer has the functions of collecting the sewage in bathrooms, toilets, kitchens and other places, conveying the sewage to water resource recovering center, eliminating pollutant and other pollutant, and releasing the sewage. With the construction and development of cities, the related sewer pipeline systems become more complex in the future, the management of pipeline data is more important, and the completed sewer system and sewage treatment plant also need to be properly operated and maintained to ensure the service level of the sewer system.
However, since the monitoring device in the sewer is in a closed and humid environment for a long time, it is often caused that when the monitoring device in the sewer transmits data to a remote system in a manner of penetrating the sewer, a transmission failure is easily caused due to poor signal quality.
Therefore, how to design a local traffic wireless data transmission method to improve the data transmission quality by using a unique local traffic wireless data transmission method is a major subject to be overcome and solved by those skilled in the art.

Detailed Description
In order to make the aforementioned features and effects of the present invention more comprehensible, embodiments accompanied with figures are described in detail below.
Fig. 1 is a schematic structural diagram of a local flow monitoring device according to the present invention. The regional flow monitoring device 1 is completely arranged in a pipeline 2, in particular an underground pipeline of the kind such as, but not limited to, a sewer. The local flow monitoring device 1 is used for monitoring and recording at least one physical parameter P in the pipeline 2. For example, but not limited to, monitoring and recording the flow of water in the pipe 2, and transmitting the physical parameter P to the remote system 3 in a manner penetrating the pipe 2. Specifically, in a conventional monitoring device, elements such as a transmission element and a battery are usually separated from the monitoring device, and the elements such as the transmission element and the battery are usually installed on the ground surface. However, if the transmission element or the battery is separately installed on the ground, it is necessary to search for a standing point such as a wall surface. When the wall is set in urban areas, most of the wall surfaces belong to private property, and when the wall surfaces are set in suburbs, the wall surfaces capable of standing are not easy to find. If the transmission device is directly installed on the ground, the transmission device and the battery may be damaged by the traffic of people and vehicles. Therefore, the main objective of the present invention is to arrange the regional flow monitoring device 1 in the pipeline 2 completely and waterproof, and to use a unique regional flow wireless data transmission method to achieve the monitoring purpose of intelligent city information bidirectional transmission.
It should be noted that in an embodiment of the present invention, the physical parameter P may include, but is not limited to, one or a combination of a flow parameter (including a forward flow parameter, a reverse flow parameter, a bidirectional flow parameter, etc.), a temperature parameter, a pressure parameter, a water quality parameter, an electric conductivity parameter, a PH parameter, or a turbidity parameter. In addition, the wireless data transmission method may use signaling protocols such as LoRa (Long Range) transmission, NB-IoT (narrowband Internet of things) transmission, Cat-M1 transmission, or 5G transmission.
Fig. 2A is a flowchart of the method for transmitting wireless data of local traffic in an unsatisfied counting period according to the present invention, and fig. 1 is combined therewith. Before the local flow monitoring device 1 monitors and records the physical parameter P in the pipe 2, the local flow monitoring device 1 sets a counting period (for example, but not limited to, 10 minutes), and sets at least one wake-up time (for example, but not limited to, 1 minute) in the counting period (S100). Then, it is determined whether or not the wake-up time is reached (S200). The local traffic monitoring device 1 includes a counting unit (not shown) for counting time, and the counting unit (not shown) continuously detects whether the counted time reaches the wake-up time. Then, when the wake-up time is reached, the local flow monitoring device 1 is woken up to enter the operating mode, and the physical parameter P of the pipeline 2 and at least one device parameter of the local flow monitoring device 1 are detected (S300). When the wake-up time (1 minute) is reached, the local traffic monitoring apparatus 1 is woken up by an internal counting unit (not shown) to enter an operating mode. At this time, the local flow rate monitoring device 1 detects physical parameters P of the pipe 2, such as, but not limited to, flow rate parameters, temperature parameters, and pressure parameters. Furthermore, the local flow monitoring device 1 may also detect its own device parameters, such as but not limited to, operating current, battery level, and operating temperature.
Specifically, since the local flow rate monitoring device 1 is externally connected to any external power source, the power consumption of the operation of the local flow rate monitoring device 1 depends only on the internal battery power of the local flow rate monitoring device 1. Therefore, when the wake-up time (1 minute) is reached, the local traffic monitoring device 1 will also detect its own device parameters to grasp its own operation capability at any time. It should be noted that in an embodiment of the present invention, the device parameters include, but are not limited to, device parameters such as operating current, battery level, operating temperature, setting of counting period and wake-up time, and whether the internal components of the local flow monitoring device 1 are operating normally.
Then, the local flow rate monitoring device 1 stores the physical parameter P and the device parameter in the storage unit (S400). Specifically, the local traffic monitoring device 1 includes a storage unit (not shown), and when the local traffic monitoring device 1 detects the physical parameter P and the device parameter, the physical parameter P and the device parameter are temporarily stored in the storage unit, so as to be taken out and transmitted to the remote system 3 during the counting period. Then, it is determined whether the count period is satisfied (S500). The local traffic monitoring device 1 includes a counting unit (not shown) for continuously detecting whether the counted time satisfies the counting period. When the counting period is not satisfied, the regional flow rate monitoring device 1 enters the sleep mode (S600) after the above steps (S100) to (S500) are performed, and returns to the step (S200).
Fig. 2B is a flow chart of data transmission and transmission in a counting period according to the method for transmitting wireless data of local traffic, which is combined with fig. 1-2A. In step (S500) of fig. 2A, if the counting unit (not shown) determines that the counting time period is satisfied, the local traffic monitoring apparatus 1 is awakened to enter the operating mode. At this time, the local traffic monitoring device 1 extracts the physical parameter P and the device parameter of the storage unit (not shown), and creates transmission data according to the physical parameter and the device parameter (S700). Then, after the transmission data is generated, before the local traffic monitoring apparatus 1 intends to transmit the transmission data to the remote system 3, the local traffic monitoring apparatus 1 determines whether there is queue data that has not been successfully transmitted (S710). When there is no queue data that has not been successfully transmitted, the local traffic monitoring device 1 transmits the transmission data to the remote system 3 by penetrating the pipe 2 (S720), and waits for the remote system 3 to respond. Specifically, when the remote system 3 receives the transmission data, the remote system 3 returns the system response to the local traffic monitoring device 1. Therefore, after the local flow monitoring device 1 transmits the transmission data to the remote system 3 by penetrating the pipe 2, it is determined whether a system response is received within the delay time (S730).
When the local traffic monitoring device 1 receives the system response within the delay time, the local traffic monitoring device 1 determines whether there is transmitted data that has not been transmitted (S740). If there is not yet transmitted transmission data, the process returns to step (S720). If there is no data to be transmitted, the local traffic monitoring apparatus 1 enters the sleep mode (S750), and waits for the next wake-up time to be started again. When the local traffic monitoring device 1 does not receive the system response within the delay time, the local traffic monitoring device 1 changes the transmission data to be transmitted at the next time into queue data, and stores the queue data in a storage unit (not shown) (S760). Finally, the procedure returns to step (S740). In particular, since a complex wake-up time may be included in the counting period. Taking the counting period of 10 minutes and the wake-up time of 1 minute as an example, the counting period includes 10 wake-up times, which means that the local traffic monitoring device 1 detects the physical parameter P and the device parameter 10 times, and then when the counting period is satisfied, the 10 parameters are converted into 10 transmission data, so that the steps (S720) to (S740) are executed 10 times before the step (S750) is performed. Therefore, the situation that the local traffic monitoring device 1 finds that the transmission of a plurality of data is not successful after continuously transmitting a plurality of data can be avoided.
Fig. 2C is a flow chart of transmission queue data in a counting period according to the method for transmitting local traffic wireless data of the present invention, and fig. 1-2B are combined. In step (S710) of fig. 2B, if there is queue data that has not been successfully transmitted previously, the local traffic monitoring device 1 preferentially transmits the queue data to the remote system 3 by penetrating the pipe 2 (S800), and waits for the remote system 3 to respond. Specifically, when the remote system 3 receives the queue data, the remote system 3 also sends back a system response to the local traffic monitoring device 1. Therefore, after the local traffic monitoring apparatus 1 transmits the queue data to the remote system 3 by penetrating the pipe 2, it is determined whether the system response is received within the delay time (S810).
When the local traffic monitoring apparatus 1 receives the system response within the delay time, it is determined whether queue data that has not been transmitted is present (S820). If there is queue data not transmitted, the process returns to step (S800). If there is no queue data that is not transmitted, the process returns to step (S720), and the local traffic monitoring apparatus 1 transmits the transmission data again. When the local traffic monitoring device 1 does not receive the system response within the delay time, the local traffic monitoring device 1 changes the transmission data to be transmitted next time into queue data (S750) and stores the queue data in a storage unit (not shown). That is, the queue data not transmitted last time plus the transmission data not transmitted this time becomes new queue data. Finally, the procedure returns to step (S740). It should be noted that in an embodiment of the present invention, the queue data may be a single data or a plurality of data, and the maximum number of data transmitted in the present invention is, for example, but not limited to 600 data, but the limit of the number of data transmitted is only to avoid the power consumption of the local traffic monitoring apparatus 1 being too large in a single data transmission. Therefore, in practical applications, the number of transmission strokes can be set by the user.
Fig. 3A is a schematic diagram of a transmission data transmission format of the local traffic wireless data transmission method according to the present invention, and refer to fig. 1 to 2C. The transmission data 100 includes time data 10, physical parameter data 20, and device data 30. Each time the counting period is satisfied, the device time (i.e. the current standard time) counted by the counting unit (not shown) of the regional flow monitoring device 1 is used as the time data 10 (taking fig. 3A as an example, the date and the time are included). Meanwhile, the local flow monitoring device 1 also retrieves the stored physical parameters from a storage unit (not shown) to generate physical parameter data 20 (fig. 3A includes a flow parameter, a total forward flow parameter, a total reverse flow parameter, a total bidirectional flow parameter, and a pressure parameter). Furthermore, the local flow monitoring device 1 also retrieves the stored device parameter generating device data 30 (fig. 3A includes the operating current and the battery level) from a storage unit (not shown).
The transmission data 100 also includes device encoding data 40 and transmission quality data 50. Specifically, in the smart city, a plurality of regional traffic monitoring devices 1 may be provided, each of the regional traffic monitoring devices 1 has a number, and the device encoding data 40 represents the number of the regional traffic monitoring device 1, so that the remote system 3 can distinguish which group of regional traffic monitoring devices 1 the received transmission data 100 belongs to. The transmission quality data 50 is a radio transmission quality indicator (RSSI) which represents the quality of the signal transmitted to the remote system 3. When the counting time period is satisfied, the local traffic monitoring apparatus 1 detects the transmission quality of the local traffic monitoring apparatus 1 and the remote system 3, and transmits the transmission quality as the transmission quality data 50 to the remote system 3, so that the remote system 3 can know the transmission quality with the local traffic monitoring apparatus 1 through the transmission data 100. When the remote system 3 receives the transmission data 100, the remote system may adjust its own antenna amplification power according to the transmission data 100 to improve the transmission quality, and then the transmission system responds to the local traffic monitoring apparatus 1.
Referring to fig. 3A, the transmission data 100 further includes a command header a and a command trailer B, the command header a is disposed at the beginning of the transmission data 100, and the command trailer B is disposed at the tail end of the transmission data 100. The command header a to the command trailer B represent a complete transmission data 100, and the local traffic monitoring apparatus 1 determines whether to provide the complete transmission data 100 according to the command header a and the command trailer B. When the transmission data 100 is transmitted to the remote system 3, the remote system 3 can determine whether the transmission data 100 is completely received according to whether the transmission data 100 includes the command header a and the command trailer B.
Fig. 3B is a schematic diagram of a system response sending format of the local traffic wireless data transmission method according to the present invention, and refer to fig. 1 to 3A. The system response sent by the remote system 3 is mainly that the remote system 3 receives the transmission data 100 transmitted by the local traffic monitoring apparatus 1 and responds with the system response 200 representing the reception of the transmission data 100. The head and tail of the system response 200 also include a command header a and a command tail B, so that the local traffic monitoring apparatus 1 can determine whether the complete system response 200 is received according to whether the system response 200 includes the command header a and the command tail B.
Fig. 3C is a schematic diagram of a set data transmission format of the local traffic wireless data transmission method according to the present invention, and refer to fig. 1 to 3B. The remote system 3 can transmit the setting data 300 to the local flow rate monitoring device 1 to remotely set the operating parameters of the local flow rate monitoring device 1. The head and tail of the configuration data 300 also include a command header a and a command tail B, so that the local traffic monitoring apparatus 1 can determine whether the complete system response 200 is received according to whether the configuration data 300 includes the command header a and the command tail B. Specifically, the remote system 3 may also transmit the setting data 300 to the local traffic monitoring device 1 when receiving the transmission data 100 or not receiving the transmission data 100 (i.e. at any time), and the local traffic monitoring device 1 may provide the parameters set by the remote system 3, such as, but not limited to, parameters including an antenna (not shown) amplification power 302, an antenna (not shown) direction 304, a counting period setting 306 (i.e. a frequency for sending the transmission data 100), a wake-up time setting 306 (i.e. a frequency for detecting the physical parameter P) and the like of the local traffic monitoring device 1.
Although the present invention has been described with reference to the above embodiments, the embodiments are merely illustrative and not restrictive, and various changes and modifications may be made by those skilled in the art without departing from the spirit and scope of the invention.
