Since the power for transmitting the notification signal should be large enough to ensure that the mobile receiving device 6 can reliably receive the notification signal, compared with the method of broadcasting the notification signal directly through the antenna by the smart chip 3, the relay transmitting device 5 is provided here for relaying the signal, the power requirement for the smart chip 3 is small, which is beneficial to the miniaturization and simplification of the smart chip 3, thereby being beneficial to reducing the price of the pipeline 2, and when a certain pipeline 2 is replaced after being deformed and broken, the cost is small (the relay transmitting device 5 does not need to be replaced together).
In practical applications, in order to facilitate maintenance of the pipe network, sand wells 90 are usually arranged at intervals (usually 25m to 50 m) along the extending direction of the pipe network; thus, in some preferred embodiments, the transshipment devices 5 are disposed in the sand wells 90 (as shown in fig. 1), one transshipment device 5 is disposed in each sand well 90, and the smart chip 3 is disposed in the portion of the pipe 2 extending into the sand well 90.

The intelligent chip 3 is in communication connection with the corresponding transfer transmitting device 5 in a wired mode or a wireless mode. For example, in fig. 1, the smart chip 3 is in communication connection with the corresponding relay sending device 5 in a wireless manner, so that the smart chip 3 and the relay sending device 5 both include wireless communication modules (such as WIFI communication modules, ZIFBEE communication modules, or other communication modules).

Therefore, the transfer device 5 in each sand well 90 corresponds to one pipeline 2, and the positioning of the deformed and broken pipelines is facilitated.
For example, in some embodiments, the detection signal sent by the smart chip 3 includes the positioning information of the smart chip 3 (the smart chip 3 includes a positioning module, such as a GPS positioning module, a beidou positioning module, etc.), so that the relay transmitter 5 adds the positioning information to the notification signal; so that the monitoring center 1 can quickly locate the deformed and broken pipeline. In other embodiments, the detection signal sent by the intelligent chip 3 contains the number information of the intelligent chip 3, so that the relay sending device 5 adds the number information to the notification signal; the monitoring center 1 can use the number information to inquire in a prestored position inquiry table to obtain the position information of the corresponding pipeline, thereby realizing the positioning of the deformed and cracked pipeline. In other embodiments, the notification signal broadcast by the relay transmitting device 5 includes the positioning information of the relay transmitting device 5 (the relay transmitting device 5 includes a positioning module, such as a GPS positioning module, a beidou positioning module, etc.), and since the relay transmitting device 5 is in one-to-one correspondence with the pipeline 2, the monitoring center 1 can quickly position the corresponding pipeline 2 by centering the positioning information of the relay transmitting device 5. In other embodiments, the notification signal broadcast by the relay sending device 5 includes the number information of the relay sending device 5, and the monitoring center 1 may query the pre-stored location lookup table by using the number information to obtain the location information of the relay sending device 5, and since the relay sending devices 5 are in one-to-one correspondence with the pipelines 2, the monitoring center 1 may quickly locate the corresponding pipelines 2 by using the location information of the relay sending devices 5.
In this embodiment, as shown in fig. 1-4, the detecting device 4 includes a metal wire, the metal wire is disposed in the pipe wall 2.1 of the pipe 2, one end of the metal wire is electrically connected to the intelligent chip 3, and the other end of the metal wire extends along the axial direction of the pipe 2 to the end of the pipe 2 away from the intelligent chip 3, and then turns around and returns along the axial direction of the pipe 2 to be electrically connected to the intelligent chip 3 (i.e. the metal wire extends along a U-shape, and both ends of the metal wire are electrically connected to the intelligent chip 3); the intelligent chip 3 detects the deformation and rupture conditions of the corresponding pipeline 2 by detecting the resistance of the metal wire. Specifically, intelligent chip 3 includes resistance detection circuit and microprocessor, this wire and resistance detection circuit connection, can make the wire tensile when 2 bending deformation of pipeline, thereby change the resistance of wire, resistance detection circuit detectable arrives the resistance change condition of wire, if pipeline 2 bending deformation is too big or the fracture, then can lead to the too big or fracture of wire tensile length, thereby make the resistance that detects too big, consequently, microprocessor accessible wire resistance's testing result judges whether pipeline 2 warp and breaks: and when the resistance of the metal wire is detected to be larger than a preset resistance threshold value, judging that the corresponding pipeline 2 is deformed and broken, otherwise, judging that the corresponding pipeline 2 is normal. Wherein, the resistance threshold value can be set according to actual needs.
The number of the detection devices 4 can be set according to actual needs; in some preferred embodiments, the detection device 4 is provided in plurality, and the plurality of detection devices 4 are uniformly arranged along the circumferential direction of the pipe 2. Therefore, when the intelligent chip 3 detects that the pipeline 2 is deformed and broken through the at least one detection device 4, the pipeline 2 is judged to be deformed and broken, and the reliability of the detection result is improved. For example, in fig. 3, four detection devices 4 are provided, and the four detection devices 4 are uniformly arranged along the circumferential direction of the pipe 2 so as to be able to be detected regardless of the direction in which the pipe 2 is deformed and broken.
It should be noted that, when the detecting device 4 is provided with a plurality of detecting devices 4 and the detecting device 4 includes a metal wire, because the intelligent chip 3 is provided with only one detecting device, a part or all of the metal wires include a connecting section extending along the circumferential direction of the pipeline 2 and a main body section extending along the axial direction of the pipeline 2, and the main body section is electrically connected with the intelligent chip 3 through the connecting section.
In some embodiments, as shown in fig. 2, each tube 2 is a full tube, such that the wires in the tubes 2 are continuous.
In other embodiments, as shown in fig. 4 and 5, the pipe 2 is formed by connecting a plurality of sections of sub-pipes 2.2, one of two abutting end surfaces of two adjacent sections of sub-pipes 2.2 is provided with a terminal pin 2.3, the other abutting end surface is provided with a corresponding terminal jack (not shown in the figure), and the terminal pin 2.3 and the corresponding terminal jack are inserted to connect the wires in the two sections of sub-pipes 2.2 (because the pipe 2 is segmented, the inner wires are correspondingly segmented). The adjacent two segments of subducting 2.2 can be connected by a connecting collar 2.4, but is not limited to the above. Generally, when the length of each pipe 2 is long, such a segmented structure can be adopted to reduce the difficulty of production and transportation.

Wherein, the length of post 2.5 is inserted to the location is longer than terminal contact pin 2.3 to the location is inserted post 2.5 and is docked the back with the location jack earlier, and terminal contact pin 2.3 reinserts in the terminal jack that corresponds.
Wherein, the quantity and the position of post 2.5 are inserted in the location can set up as required, for example in fig. 5, the post 2.5 is inserted in the location is provided with four to evenly arrange along the circumference of butt joint terminal surface.
In order to realize the patrol movement of the mobile receiving device 6, the mobile receiving device 6 can be arranged on a mobile carrier 7, which is a vehicle or an unmanned aerial vehicle. The mobile carrier 7 is, for example, a special vehicle which patrols along a preset route. For example, the mobile carrier 7 is a public transportation means such as a bus or a taxi, and the configuration and operation costs can be reduced by installing the mobile receiving apparatus 6 on an existing public transportation means.
In practical use, the intelligent chip 3 may periodically send the detection signal according to a preset period, and the relay sending device 5 may periodically broadcast the first notification signal according to a first preset period under normal conditions (the first preset period may be the same as or different from the sending period of the intelligent chip 3), and when the deformation and rupture of the pipeline 2 are detected, the relay sending device 5 periodically broadcasts the second notification signal according to a second preset period, and the second preset period is shorter than the first preset period (i.e. the emission frequency of the second notification signal is higher than the emission frequency of the first notification signal); therefore, under normal conditions, the frequency for transmitting the notification signal can be set to be lower so as to reduce energy consumption, and when the deformation and the breakage of the pipeline 2 are detected, the notification signal is transmitted at a higher frequency, so that the mobile receiving device 6 can receive the notification signal in time, and the monitoring center 1 can find the deformation and the breakage of the pipeline in time.
In practical use, the mobile receiving device 6 is further configured to send a response signal back to the relay transmitting device 5 after receiving the notification signal, so that the relay transmitting device 5 knows whether any mobile receiving device 6 receives the notification signal. Thus, the relay transmitter 5 is also used to receive the response signal sent back by the mobile receiver 6.
In practical use, the relay transmitter 5 is further configured to shorten the second preset period (i.e. increase the transmission frequency of the second notification signal) if the response signal sent back by the mobile receiver 6 is not received within the first preset time from the time of broadcasting the second notification signal for the first time. To improve the probability that the mobile receiving device 6 receives the second notification signal in time.
In practical use, the relay transmitter 5 is further configured to broadcast a relay command to enable the other relay transmitters 5 to start a relay function to relay the second notification signal if the response signal sent back by the mobile receiver 6 is not received within a second preset time period from the time when the second notification signal is broadcast for the first time. When the relay function is started by other relay sending devices 5, the second notification signal is received and then broadcasted in a broadcasting manner, so that the coverage area of the second notification signal is greatly increased, and the probability that the mobile receiving device 6 receives the second notification signal in time is further improved.
Based on the above intelligent pipe network detection system, the embodiment of the present application further provides an exemplary intelligent pipe network detection method, where the method is applied to the transfer transmitting device 5 of the intelligent pipe network detection system, and includes the steps of:
A1. receiving a detection signal periodically sent by an intelligent chip;
A2. judging whether the corresponding pipeline deforms and breaks according to the detection signal;
A3. if not, generating a first notification signal, and periodically broadcasting the first notification signal according to a first preset period;
A4. if so, generating a second notification signal, and periodically broadcasting the second notification signal according to a second preset period; the second preset period is shorter than the first preset period.
The intelligent chip sends out a first detection signal indicating that the pipeline is normal when the pipeline is normal, and sends out a second detection signal indicating that the pipeline is deformed and broken when the pipeline is deformed and broken. Therefore, in step a2, if the detection signal is the first detection signal, it is determined that the corresponding pipe is normal, and if the detection signal is the second detection signal, it is determined that the corresponding pipe is deformed and broken. For example, the data frame of the detection signal includes a status bit, which is 0 in the first detection signal and 1 in the second detection signal, so that in step a2, whether the detection signal is the first detection signal or the second detection signal is determined by detecting whether the status bit in the data frame of the detection signal is 0 or 1.
In some preferred embodiments, after step a4, the method further comprises:
A5. if the response signal sent back from the mobile receiving device is not received within the first preset time from the time of broadcasting the second notification signal for the first time, the second preset period is shortened (i.e. the frequency of sending the second notification signal is increased).
Thereby increasing the probability that the mobile receiving device 6 will receive the second notification signal in time.
In some preferred embodiments, after step a4, the method further comprises:
A6. if the response signal sent back by the mobile receiving device is not received within the second preset time from the time of broadcasting the second notification signal for the first time, a relay instruction is broadcasted, so that other relay sending devices start a relay function to relay the second notification signal.
Therefore, the coverage area of the second notification signal is greatly increased, and the probability that the mobile receiving device 6 receives the second notification signal in time is further improved.
In some preferred embodiments, after step a4, the method further comprises:
A7. if N response signals sent back by different mobile receiving devices are received from the time when the second notification signal is broadcast for the first time, the second preset period is increased (i.e. the frequency of sending the second notification signal is decreased), where N is a preset threshold of times and is a positive integer.
In practical application, after receiving the second notification signal, the mobile receiving device 6 may not be able to forward the second notification signal to the monitoring center 1 in time due to abnormal network connection or other faults, but the probability that none of the N mobile receiving devices 6 can forward is small, so when there are N mobile receiving devices 6 receiving the second notification signal and sending back an acknowledgement signal, the probability that the monitoring center 1 receives the second notification signal is high, and at this time, the sending frequency can be reduced to reduce energy consumption. The second predetermined period may be returned to the initial value or increased to be the same as the first predetermined period. Where N may be set according to actual needs, e.g. N = 6.
In some embodiments, the first notification signal and the second notification signal each include positioning information of the corresponding smart chip. The positioning information is extracted from the detection signal sent by the intelligent chip.
In some embodiments, the first notification signal and the second notification signal each include number information of the corresponding smart chip. The number information of the intelligent chip is extracted from the detection signal sent by the intelligent chip.
In some embodiments, the first notification signal and the second notification signal each include the positioning information of the relay transmitter 5.
In some embodiments, the first notification signal and the second notification signal each include the number information of the relay transmission device 5.
In summary, although the present invention has been described with reference to the preferred embodiments, the above-described preferred embodiments are not intended to limit the present invention, and those skilled in the art can make various changes and modifications without departing from the spirit and scope of the present invention, which are substantially the same as the present invention.
