Description

Technical Field
The utility model relates to the technical field of wireless communication network equipment for collecting sensor information, in particular to a slope monitoring device based on an NB-IOT module.
Background
The highway high slope monitoring has the characteristics of complex equipment installation environment and long monitoring period, so that the monitoring device can be adapted to the monitoring of the highway high slope, and the power consumption of the monitoring device can be reduced as much as possible, so that the battery can be used for supplying power to the monitoring device for a long time. The prior patent with the publication number of CN215116260U discloses a passive wake-up system for detecting landslide based on the Internet of things, and landslide data can be acquired by waking up a monitor in a dormant state when a side slope slides through a set passive wake-up module.
Although the power consumption of the monitor can be reduced by the technical scheme, the monitor can only collect data when the slope slides, and cannot monitor the slope under normal conditions, so that the monitor has certain limitation. And moreover, the monitor adopts the LoRa communication equipment to communicate, so that a base station is additionally built in a monitoring area, the energy consumption of the LoRa communication equipment is high, and if long-time monitoring is to be realized, a cable is paved to supply power to the LoRa communication equipment.
In order to power the communication device without wiring, a communication module with low power consumption may be used for communication. For example, patent publication number CN212785868U discloses a battery-powered all-in-one sensor collector based on NBIOT transmission, and the sensor collector adopts a low-power NB-IOT module for communication, so that the battery can be directly used for long-time power supply, and no additional cable is required to be laid for power supply of communication equipment. The method is suitable for the monitoring conditions of complex installation environment and long monitoring period.
Although the NB-IOT module has the characteristics of low power consumption, the NB-IOT module can directly use a battery for long-time power supply. However, the NB-IOT module has a small amount of data to transmit, and can only transmit a small amount of data to the remote end per unit time. If the slope landslide is met, a large amount of real-time data needs to be collected for analysis, and the NB-IOT module cannot meet the data transmission requirement.

Detailed Description
Embodiments of the technical scheme of the present utility model will be described in detail below with reference to the accompanying drawings. The following examples are only for more clearly illustrating the technical aspects of the present utility model, and thus are merely examples, and are not intended to limit the scope of the present utility model.
The slope monitoring device schematic diagram based on NB-IOT module as shown in FIG. 1, the monitoring device comprises a monitoring sensor and a data acquisition terminal, the data acquisition terminal is in signal connection with the monitoring sensor, and the slope monitoring device further comprises:
the NB-IOT module and the high-speed wireless communication module are in communication connection with the data acquisition terminal;
the communication module change-over switch is connected in series in the power supply loops of the NB-IOT module and the high-speed wireless communication module, and is configured to disconnect the power supply loop of the NB-IOT module and switch on the power supply loop of the high-speed wireless communication module when the slope slides.
Specifically, the monitoring device comprises a monitoring sensor, a data acquisition terminal, an NB-IOT module, a high-speed wireless communication module and a communication module change-over switch. The data acquisition terminal is provided with a signal interface, such as an RS232 interface, a USB interface and the like, and the monitoring sensor for monitoring the slope can be connected with the data acquisition terminal through the signal interface so as to send the data detected in real time to the data acquisition terminal. The data acquisition terminal is also provided with a communication interface, such as an RS485 interface, and the NB-IOT module and the high-speed wireless communication module used for the communication connection between the data acquisition terminal and the remote terminal can be in communication connection with the data acquisition terminal through the communication interface, and the data acquisition terminal can send stored data to the remote terminal through the NB-IOT module or the high-speed wireless communication module through the Internet of things or the Internet so as to realize monitoring of the slope.
The power supply ends of the NB-IOT module and the high-speed wireless communication module can be connected with a power supply through a communication module change-over switch, and the power supply can be a battery, so that additional wiring is not needed for supplying power to the NB-IOT module and the high-speed wireless communication module so as to install the monitoring device.
Normally, the data acquisition terminal transmits less data to the remote terminal because less data is required for monitoring. The communication module change-over switch can conduct a power supply loop between the power supply and the NB-IOT module and cut off the power supply loop between the high-speed wireless communication module and the power supply. Thus, the data acquisition terminal can send data to the remote terminal through the NB-IOT module. Because NB-IOT module has the characteristics of low-power consumption, so can reduce battery power consumption to the power supply time of extension battery.
When landslide occurs on a slope, the data acquisition terminal needs to transmit a large amount of data to the remote terminal because the remote terminal needs a large amount of data for real-time analysis. The communication module change-over switch can conduct a power supply loop between the high-speed wireless communication module and the power supply, and cut off the power supply loop between the power supply and the NB-IOT module. Therefore, the data acquisition terminal can send a large amount of data to the remote terminal in real time through the high-speed wireless communication module so as to meet the data requirement of real-time analysis of the remote terminal.
After the landslide is finished, the communication module change-over switch can automatically restore to be conducted with a power supply loop between the power supply and the NB-IOT module, and the power supply loop between the high-speed wireless communication module and the power supply is cut off so as to prolong the power supply time of the battery.
It should be understood that the present embodiment is illustrated with only a single monitoring sensor, but the application is not limited to the number and type of monitoring sensors. The monitoring device can be provided with a plurality of different signal interfaces so as to be connected with a plurality of different monitoring sensors, such as a displacement sensor, a stress meter and the like, thereby realizing the omnibearing monitoring of the side slope.
In this embodiment, optionally, as shown in fig. 2, the communication module change-over switch includes:
the landslide monitor is configured to monitor the stable state of the side slope in real time, and continuously sends out a trigger signal when the side slope slides;
the module change-over switch is connected in series in the power supply loop of the NB-IOT module and the high-speed wireless communication module and is connected with the landslide monitor in a signal mode, and when a trigger signal is received, the module change-over switch cuts off the power supply loop of the NB-IOT module and switches on the power supply loop of the high-speed wireless communication module.
Specifically, the communication module change-over switch is composed of a landslide monitor and a module change-over switch. The landslide monitor can detect the state of the side slope, and can immediately send out a trigger signal when the side slope slides. The signal output end of the landslide monitor can be in signal connection with the trigger signal end of the module change-over switch, when the trigger signal end receives the trigger signal, the module change-over switch can immediately disconnect the power supply loop of the NB-IOT module and conduct the power supply loop of the high-speed wireless communication module, so that a power supply supplies power to the high-speed wireless communication module, and the communication equipment between the data acquisition terminal and the remote terminal is switched.
In this embodiment, optionally, the landslide monitor includes a displacement sensor in signal connection with the module switch. Specifically, the displacement sensor can be arranged on the side slope to detect whether the side slope of the spoil field moves, and when the side slope is detected to move, the displacement sensor immediately outputs a trigger signal. It should be understood that the displacement sensor is only used for illustration, but the present application is not limited thereto, and the landslide monitor may be any other device that can be used to monitor whether a landslide occurs on a slope, for example, a stress meter may be disposed on a fixed anchor cable of the slope to detect whether the stress of the fixed anchor cable exceeds a threshold value, and the stress meter outputs a trigger signal immediately when detecting that the stress of the fixed anchor cable exceeds the threshold value.
In this embodiment, optionally, as shown in fig. 3, the module change-over switch includes:
the non-inverting input end of the voltage comparator is connected with the landslide monitor in a signal manner, and the inverting input end of the voltage comparator is connected with a reference voltage source;
the base electrode of the triode is electrically connected with the output end of the voltage comparator, and the collector electrode of the triode is connected with a power supply;
and one end of the coil of the relay is connected with the emitter of the triode, the other end of the coil of the relay is grounded, the normally closed switch is connected in series with the power supply loop of the NB-IOT module, and the normally open switch is connected in series with the power supply loop of the high-speed wireless communication module.
Specifically, the module change-over switch comprises a voltage comparator, a triode and a relay. The communication input end of the voltage comparator can be electrically connected with the output end of the displacement sensor, the inverting input end of the voltage comparator can be connected with a low-level reference voltage source, and erroneous judgment of the displacement sensor due to a trigger signal output by micro movement is avoided. The reference voltage source may be provided by a battery. The output end of the voltage comparator can be electrically connected with the base electrode of the triode, the collector electrode of the triode can be electrically connected with the battery, and the emitter electrode can be grounded through the coil of the relay.
Therefore, when the slope slides, the displacement sensor outputs a high-level trigger signal, and the voltage comparator outputs a high-level signal to trigger the conduction between the collector and the emitter of the triode as the level of the non-inverting input end of the voltage comparator is higher than that of the inverting input end, so that the battery-driven relay is attracted to the normally-open switch, and the normally-closed switch is disconnected. The normally open switch of the relay is connected in series in a power supply loop between the high-speed wireless communication module and the battery, and the normally closed switch is connected in series in the power supply loop between the NB-IOT module and the battery, so that the power supply loop of the NB-IOT module can be disconnected and the power supply loop of the high-speed wireless communication module can be conducted.
In this embodiment, optionally, the power supply circuit further comprises a timing switch, and the timing switch is connected in series with the power supply circuit of the NB-IOT module. Specifically, under normal conditions, the slope does not need to be monitored in real time, so the data acquisition terminal does not need to acquire data in real time. In order to further reduce the power consumption of the monitoring device, most slope monitoring devices are currently set to collect data at regular time. Therefore, the timing switch can be connected in series with the power supply loop of the NB-IOT module, and the timing switch can be set to be opened for a long time and closed only when the data acquisition terminal acquires data, so that the battery power consumption is further reduced.
In this embodiment, optionally, the high-speed wireless communication module is a 5G module. Specifically, the 5G module has the characteristics of high transmission rate, long transmission distance and the like, and can meet the real-time data transmission requirement when the side slope slides. In addition, the network can be accessed by relying on the existing telecommunication base station, other base stations are not required to be installed, and the monitoring device is convenient to install.
The above embodiments are only for illustrating the technical solution of the present utility model, and are not limiting; although the utility model has been described in detail with reference to the foregoing embodiments, it will be understood by those of ordinary skill in the art that: the technical scheme described in the foregoing embodiments can be modified or some or all of the technical features thereof can be replaced by equivalents; such modifications and substitutions do not depart from the spirit of the utility model, and are intended to be included within the scope of the appended claims and description.
