Detailed Description
The following is a further detailed description of the embodiments:
example 1
Substantially as shown in figure 1: the energy-saving device for monitoring the stress and strain of the concrete comprises a detection module and a control module, wherein the detection module is used for monitoring and obtaining the stress information of the concrete; in this embodiment, taking concrete of the bridge as an example, the detection module adopts a surface strain gauge.
The storage module is used for storing a detection frequency table, wherein the detection frequency table comprises preset conditions and detection frequencies corresponding to the preset conditions, and the detection frequency table comprises interval duration; in this embodiment, the detected frequency table is shown in table one, taking the traffic flow as an example.
List one
| Preset conditions | The traffic flow is less than X1 | X1 is less than or equal to the traffic flow and less than X2 | X2 is less than or equal to the traffic flow |
| Detecting frequency | f1 | f2 | f3 |
| Duration of interval | T 1 -1 | T 2 -1 | T 3 -1 |
Wherein f1 is less than f2 and less than f3, namely, when the traffic flow is large, the detection frequency is large, and when the traffic flow is small, the detection frequency is small.
The acquisition module is used for acquiring the condition factors of the concrete; taking traffic flow as an example, because the traffic conditions of the bridge are all detected by a special detection system, in the embodiment, after the authorization of a detection system mechanism is obtained, an acquisition module communicates with the detection system and acquires the condition factors of concrete, the acquisition comprises two modes of active acquisition and passive acquisition, wherein the active acquisition refers to the acquisition of the condition factors after the acquisition module is inquired from the detection system after the communication with the detection system, the passive acquisition refers to the transmission of the condition factors to the acquisition module by the detection system, and the acquisition module only needs to receive the condition factors. The collected traffic flow is set to be X, i.e., in this embodiment, the condition factor is X.
The matching module is used for comparing the acquired condition factors with the detection frequency table and matching the acquired condition factors with corresponding detection frequencies; and setting the acquired condition factor X > X2, and matching the detection frequency matched by the matching module from the detection frequency table to be f3.
And the control module is used for controlling the detection module to work according to the matched detection frequency and controlling the detection module to sleep in the period between two adjacent monitoring operations. Setting the matched detection frequency f3 to 0.1Hz, then T 3 The corresponding interval duration is 10s. That is, the detection module performs a monitoring operation every 10s, so the control module will control the detection module to sleep in a nine second period after monitoring and obtaining the concrete stress information in the first second in a period of 10s.
Specifically, in this embodiment, the control module includes a timing unit, a calculating unit, and a triggering unit, where the timing unit is configured to start timing to obtain a timing duration when the matching module matches the detection frequency, and the triggering unit triggers the detection module to work when the timing duration is equal to the interval duration, the calculating unit is configured to calculate the timing duration according to the interval duration, and when the calculating unit obtains that the timing duration is equal to the interval duration, the triggering unit is further configured to trigger the timing unit to restart timing. That is, if the detection frequency is set to be 0.1Hz, the interval duration is 10s, and when the timing duration is 10s, the timing duration calculated by the calculating unit is 10s, and at this time, the triggering unit triggers the timing unit to count again.
The input module is used for inputting the modification information; in this embodiment, the input module adopts a keyboard, and in other embodiments, the input module may be other input peripherals such as a handwriting board and a microphone.
And the correction module is used for modifying the preset detection frequency table according to the modification information.
Based on the above-mentioned energy-saving device for monitoring the stress strain of concrete, as shown in fig. 2, the embodiment also discloses an energy-saving method for monitoring the stress strain of concrete, which comprises the following steps:
the acquisition step: acquiring condition factors of concrete; in this embodiment, taking the condition factor as an example of the vehicle flow, the collected vehicle flow is set to be X, that is, the condition factor is set to be X.
Matching: matching corresponding detection frequencies from a preset detection frequency table according to the acquired condition factors; in this embodiment, as shown in table one, when the collected traffic flow X is less than X1, the matched detection frequency is f1, when the collected traffic flow X is greater than or equal to X1 and X is less than X2, the matched detection frequency is f2, and when the collected traffic flow X is greater than or equal to X2, the matched detection frequency is f3.
The detection step comprises: monitoring the concrete by adopting a detection module according to the matched detection frequency to obtain stress information; specifically, when the detection frequency is matched, starting to count to obtain a count time length, triggering the detection module to work when the count time length is equal to the interval time length, and restarting to count at the same time to obtain a new count time length; in this embodiment, the collected traffic flow X is set to be greater than or equal to X2, so that the matched detection frequency is f3, f3=0.1 Hz is set, that is, in the detection step, the detection module 10s performs a monitoring operation, specifically, starts timing when the detection frequency is matched, performs a monitoring operation when the timing duration of the timing is 10s, and simultaneously resumes the timing, and performs a monitoring operation again when the timing duration of the timing is 10s again.
Dormancy step: the detection module is controlled to sleep in the period between two adjacent monitoring operations, namely the detection module will sleep after completing one monitoring operation, and the detection module will sleep again after restarting the monitoring operation when the next monitoring operation.
And (3) correcting: and inputting modification information, and modifying a preset detection frequency table according to the input modification information.
Example two
The first difference from the embodiment is that in this embodiment, the control module includes a timing unit, a calculating unit, and a triggering unit, where the timing unit is configured to start timing to obtain a timing duration when the matching module matches the detection frequency, the calculating unit is configured to calculate the timing duration according to the interval duration, and when the calculating result shows that the timing duration is multiple of the interval duration, the triggering unit triggers the detection module to work.
In this embodiment, f3=0.1 Hz is also set for example with the matched detection frequency being f3, and the interval duration is 10s, so when the detection frequency is matched, the timing unit starts to count to obtain the timing duration, the calculating unit calculates the timing duration, and when the timing duration is calculated to be equal to the multiple of the interval duration, that is, when the timing duration is 10s, 20s, 30s, etc., the triggering unit triggers the detection module to work.
Example III
The difference from the first and second embodiments is that in this embodiment, the power supply module further includes a detection module;
the electric quantity detection module is used for detecting the residual electric quantity of the power supply module;
the communication module is used for communicating with the monitoring center;
the detection module comprises a detection unit and a processing unit, wherein the detection unit is used for acquiring stress parameters, and the processing unit is used for processing the acquired stress parameters to obtain stress information;
the storage module is further preset with power consumption of the detection module in a normal state, a communication state and a storage state, wherein the normal state refers to the power consumption when the detection module collects stress parameters and processes the stress parameters to obtain stress information, the communication state refers to the power consumption when the detection module collects the stress parameters and transmits the stress parameters back to the communication module, in the process, in order to ensure that the stress parameters meet the information transmission requirement, format processing is further needed on the stress parameters so that the stress parameters can meet the information transmission format requirement, the storage state refers to the power consumption when the stress parameters are collected and stored in the operation flow, and other processing operations on the stress parameters are not involved in the process, wherein the power consumption in the normal state is greater than the power consumption in the communication state and greater than the power consumption in the storage state.
The storage module is also preset with a monitoring level table, wherein the monitoring level table comprises a monitoring period and a monitored importance level, as shown in a second table.
Watch II
| Monitoring period of time | T1-T2 | T2-T3 | T3-T4 |
| Importance level | Third class | First class | Second class |
Of these, one is an important class, two is a secondary class, and three is a non-important class.
And the analysis module is used for analyzing whether the residual electric quantity can meet the electric quantity requirement of the detection module in the residual period according to the residual electric quantity detected by the electric quantity detection module.
And the control module is also used for adjusting and controlling the working state of the detection module according to the residual electric quantity detected by the electric quantity detection module and the monitoring grade table.
T1-T4 are described as a cycle. In order to ensure that the power supply module can maintain the operation of the detection module in one period, in this embodiment, the working state of the detection module is also adjusted according to the importance level of the monitoring period; setting the power in the normal state as P1, the power in the communication state as P2, the power in the storage state as P3, and the power consumption in the sleep mode as P4, wherein P1 is more than P2 and more than P3 is more than P4.
Setting the residual electric quantity detected by the electric quantity detection module as X and the residual time in the period as t, then the electric quantity required by the detection module working in a normal working state in the period residual time as P1t, analyzing the residual electric quantity X and the required electric quantity P1t by the analysis module at the moment, if the residual electric quantity X is smaller than the required electric quantity P1t, indicating that the residual electric quantity can not meet the electric quantity requirement of the detection module in the residual period, and therefore, adjusting the working state of the detection module to ensure that the power supply module can maintain the electric quantity requirement of the detection module in the residual period.
In addition, the importance degree of the monitoring operation in different monitoring periods in the same period is considered to be different, for example, the stress strain condition of the concrete needs to be focused during the peak period of the traffic flow, namely the monitoring result is needed, and the monitoring result does not need to be focused at the late night time when the traffic flow is small or the vehicle does not pass for a long time.
Therefore, in the scheme, the importance levels of the monitoring operations in different monitoring periods are also divided according to the different monitoring periods, and for the monitoring period with the importance level equal to the first importance level, namely, a complete monitoring process needs to be completed in the monitoring period, namely, the detection module needs to work normally; for the monitoring period with the importance level of second class, the importance is reduced compared with first class, so that the detection module can work in a mode in a communication state, namely, after the stress parameter is acquired by the detection module, the stress parameter is transmitted back to the monitoring center through the communication module, and the corresponding stress information is obtained by processing the stress parameter by the monitoring center, and in the state, the power consumption of the detection module is reduced because the processing operation is not performed; for the monitoring period with three importance levels, the importance is lowest, so that the detection module can work in a mode in a storage state, namely, after the stress parameters are collected by the detection module, the stress parameters are not subjected to any processing operation, but are directly stored, and the stress parameters are not required to be transmitted back to the monitoring center, and the power consumption of the detection module in the state is further reduced. The processing of the stress parameters can be performed after the stored stress parameters are read in the subsequent time.
The foregoing is merely an embodiment of the present invention, and a specific structure and characteristics of common knowledge in the art, which are well known in the scheme, are not described herein, so that a person of ordinary skill in the art knows all the prior art in the application day or before the priority date of the present invention, and can know all the prior art in the field, and have the capability of applying the conventional experimental means before the date, so that a person of ordinary skill in the art can complete and implement the present embodiment in combination with his own capability in the light of the present application, and some typical known structures or known methods should not be an obstacle for a person of ordinary skill in the art to implement the present application.
