Description
Technical Field
The utility model relates to a sensor technical field especially relates to wireless monitor terminal of vibrating wire sensor intelligence and system, can realize ultralow power consumption control, long-time wireless detection to have according to the detection conditions automatic adjustment vibrating wire sensor signal acquisition frequency, automatic calling product basic parameter information of marking that dispatches from the factory, plug-and-play etc. function, thereby have implementation convenience, reliability height and advantage such as low cost.
Background
In the construction process of tunnel bridges and foundation pits in the construction field in the current traffic field, vibrating wire sensors are widely used for monitoring the monitoring of the axial force of an inner support, the stress of a supporting structure, the soil pressure and the like in the construction process. The vibrating wire sensor reading instrument, the detection terminal or the system is used for exciting the built-in vibrating wire of the vibrating wire sensor and reading the natural vibration frequency of the vibrating wire.
Depending on the work basis of earlier project teams and related teams inside and outside the industry, the developed vibrating wire sensor wireless monitoring terminal adopts a sleep technology, so that the standby power consumption in a sleep state is reduced, the test use time under the condition of rated energy supply is effectively prolonged, for example, the self-carried power supply can finish the automatic data acquisition of the vibrating wire sensor within 1 month to 1 year, and the corresponding vibrating wire sensor signal is output to the outside through a wireless communication module, so that the practical value is quite high, but the vibrating wire sensor wireless monitoring terminal can only acquire the vibrating wire sensor signal according to the set detection frequency, the service life of the vibrating wire sensor wireless monitoring terminal is obviously shortened when the daily detection frequency is higher, and the requirements of improving the detection data intensity and real-time when the output signal of the vibrating wire sensor exceeds the preset value when the detection frequency is lower can not be met, therefore, the contradiction that the daily test of the product requires low detection frequency due to long service time and the detection frequency is high due to real-time property in emergency occurs.
The traditional vibrating wire sensor detection terminal obtains an output signal of the vibrating wire sensor, and when data processing is carried out, basic parameters of the vibrating wire sensor, such as a sensor coefficient k value, a temperature compensation b value, a vibrating wire sensor measuring range, an initial frequency and the like, which are calibrated before leaving a factory are needed. At present, the parameters are generally registered on a paper parameter table when leaving a factory, are shipped together with a sensor and are frequently lost in real time when being used on site, so that data are difficult to accurately calculate and process; in contrast, patents CN 205449100U, CN 108534806 a and CN 206488790U all propose that memories storing the factory-calibrated basic parameters such as the sensor coefficient k value and the temperature compensation b value are embedded in the vibrating wire sensor, so as to avoid data loss, but also have the problems that the required memory space is large, the working efficiency and the intelligence degree of wireless transmission after data reading are required to be improved, and the implementation cost is required to be reduced.
When the traditional vibrating wire sensor detection terminal collects signals output by a vibrating wire sensor, at least after the traditional vibrating wire sensor detection terminal is physically connected with a vibrating wire sensor signal collection wire, the signal collection work of the vibrating wire sensor can be started only by operating a related button or switch, so that the arrangement of a starting button or switch on the vibrating wire sensor detection terminal is also considered, and meanwhile, if the traditional vibrating wire sensor detection terminal works under severe conditions such as water, high humidity, dust and the like for a long time, the cost for arranging the starting button or switch is required to be paid, and the problem of reliability reduction also exists.
The traditional vibrating wire sensor wireless monitoring system does not consider the situation of long-term use of wireless communication technology by means of power supply of the traditional vibrating wire sensor, and generally adopts an external power supply without considering the power consumption of the vibrating wire sensor wireless monitoring terminal and the system, so that the type of the adopted wireless communication technology which can be used for a long time by means of power supply of the traditional vibrating wire sensor is required to be further designed and determined. In addition, corresponding to a specific available technology, for example, patents such as CN 206472310U, CN204082132U propose to adopt the Zigbee technology, but none of them describes, analyzes and proposes that the technology currently does not have a time calibration function for each detection terminal, and therefore, the detection period of each vibrating wire sensor wireless monitoring terminal adopting the Zigbee technology will gradually become confused with the increase of the usage time, which finally results in the problem that the data acquisition period and time of each vibrating wire sensor are inconsistent, and a solution is proposed in a targeted manner. Similarly, after the vibrating wire sensor wireless monitoring system adopts the Zigbee technology, how to monitor the health condition of the Zigbee network, and how to ensure that each repeater with redundancy works normally in addition to determining that each vibrating wire sensor wireless monitoring terminal works normally, so that a faulty repeater can be found and maintained as soon as possible, and thus, the problem that the reliability of system operation is reduced and the like because maintenance is performed only when all redundant repeaters are faulty and signals cannot be output is avoided in a certain link. In addition, after the Zigbee technology is adopted, the wireless monitoring system of the vibrating wire sensor also relates to a repeater and a concentrator which need to be powered by an external power supply, but in the actual use process, the condition of external power supply interruption exists, so that the problems that the data of the vibrating wire sensor cannot be sent out and the like can be caused.
The existence of the various problems or the appearance of the wireless vibrating wire sensor monitoring terminal and system which can realize the long-term no need of external power supply to the vibrating wire sensor detection terminal, can acquire and transmit data wirelessly and do not need personnel to patrol and examine reading operation in the current domestic and foreign markets. Based on the above, the creative development work is carried out based on the above problems, and a solution is provided, so that the vibrating wire sensor wireless monitoring terminal and the system with practical values are developed, the use and verification work of first-batch delivered products is smoothly completed, the perfect unification of the test using duration and the test real-time performance under emergency conditions is realized by confirming the wireless monitoring terminal and the system compared with the existing products and patent technical schemes, the implementation convenience, the operation reliability and the intelligentization level are obviously improved, and the production and use cost is reduced.
