In monitoring scenes, such as outdoor monitoring scenes of a dam reservoir, the data acquisition device is connected with different kinds of sensor equipment and used for monitoring precipitation, flow, osmotic pressure, water level and the like of the dam reservoir.
In order to ensure that the data acquisition unit on the market can work normally under the abnormal condition of the external power supply system, a built-in battery is generally added as an emergency power supply to supply power under the abnormal condition of the external power supply system.
The inventor finds that most of data acquisition units are always in a working state for ensuring the optimal acquisition performance, however, the electric quantity of a rechargeable battery built in the data acquisition unit is limited, so that the built-in battery serving as an emergency power supply cannot work for a long time under the abnormal condition of an external power supply system (such as power supply line abnormality caused by a large amount of rainfall) and further the problem that the endurance time of the data acquisition unit is low under the abnormal condition of the external power supply system and further the reliability of data acquisition is low is caused.
For the problems, the inventor designs a data acquisition device and a data acquisition system, the data acquisition is realized by matching a logic main control unit and an acquisition main control unit, the logic main control unit can control the power supply of the acquisition main control unit, the power supply of the acquisition main control unit can be controlled to be turned on in a data acquisition time period, the power supply of the acquisition main control unit can be controlled to be turned off in a data acquisition non-time period, and the data acquisition non-time period is set to be in a sleep mode, so that the whole power consumption of the data acquisition unit is saved, and the endurance time and the reliability of the data acquisition can be improved under the abnormal condition of an external power supply system.
Based on the foregoing, the present application provides a data acquisition device, as shown in fig. 1, where the data acquisition device may include a logic main control unit 10 and an acquisition main control unit 20, and the logic main control unit 10 is electrically connected with the acquisition main control unit 20.
In the data acquisition device designed as above, the power supply of the acquisition main control unit 20 is controlled by the logic main control unit 10, and during the data acquisition period, the logic main control unit 10 can firstly control the power supply of the acquisition main control unit 20 to be turned on and send a data acquisition instruction to the acquisition main control unit 20, wherein the data acquisition instruction can include information such as the data type of the sensor to be acquired.
After the power is turned on, the acquisition main control unit 20 firstly completes initialization, acquires corresponding sensor data according to the received data acquisition instruction after the initialization operation is completed, obtains target data, and then transmits the target data back to the logic main control unit 10. The collection master control unit 20 may collect sensor data in any current collection mode. For example, as shown in fig. 1, the acquisition master unit 20 may be electrically connected to a plurality of sensors a, which are different types of sensors, so as to acquire sensor data of the plurality of sensors a. As another example, as shown in fig. 2, the data acquisition device is a multi-channel multi-sampling data acquisition device, each channel is correspondingly connected with one type of sensor a to perform data acquisition, on this basis, the data acquisition device may further include multiple types of sampling circuits, sampling selection circuits and channel selection circuits, the acquisition main control unit 20 is electrically connected with the multiple types of sampling circuits, sampling selection circuits and channel selection circuits, and after receiving an acquisition instruction, the acquisition main control unit 20 controls the sampling selection circuits and the channel selection circuits to conduct the target sampling circuits and the target acquisition channels, so that the data acquisition of the corresponding sensors is performed through the conducted target sampling circuits and the sensors connected with the target acquisition channels and the corresponding channels.
The logic main control unit 10 can receive the target data returned by the acquisition main control unit 20, the logic main control unit 10 can control the power supply of the acquisition main control unit 20 to be turned off after the acquisition main control unit 20 finishes transmitting the target data, the target data is uploaded to the cloud, and the logic main control unit 10 sets itself to be in a sleep mode after the uploading of the target data is completed. The sleep mode refers to a mode in which the logic main control unit 10 is in a standby state, and may be awakened by an external signal or automatically awakened by a preset time interval, etc.
The data acquisition device is designed by adopting two main control designs, namely a logic main control unit and an acquisition main control unit, the logic main control unit designed by the scheme can control the power state of the acquisition main control unit, control the power on of the acquisition main control unit in a data acquisition stage, and send a data acquisition instruction to the acquisition main control unit, so that the acquisition main control unit can acquire target data according to the data acquisition instruction after the power on and transmit the target data back, and the logic main control unit turns off the power of the acquisition main control unit after the target data back is finished, so that the acquisition main control unit does not work under the condition of not carrying out data acquisition, and further the power consumption of the data acquisition device is reduced; in addition, after the target data is uploaded to the cloud, the logic main control unit designed by the scheme can set the logic main control unit into a sleep mode, so that the power consumption brought by the logic main control unit is further reduced under the condition that data acquisition is not carried out, and the power consumption of the whole data acquisition device is further reduced, and the endurance time and the reliability of the data acquisition can be improved under the abnormal condition of an external power supply system.
In an alternative implementation manner of the present embodiment, as shown in fig. 3, the logic main control unit 10 further includes a communication module 110, the data collecting device further includes a power supply battery 30, the power supply battery 30 may be electrically connected with the logic main control unit 10, and on this basis, a manner in which the logic main control unit 10 uploads the target data to the cloud end may specifically use the communication module 110 to communicate with the cloud end, so that the communication module 110 uploads the target data to the cloud end.
In the case that the logic main control unit 10 includes the communication module 110, the present solution may further control the operation state of the communication module according to the battery voltage of the power supply battery 30 and the power supply state of the external power source. Specifically, since the logic main control unit 10 is electrically connected to the power supply battery 30, the logic main control unit 10 may obtain battery information of the power supply battery 30, for example, obtain information such as an electric quantity or a battery voltage of the power supply battery 30, and the logic main control unit 10 may obtain a power supply state of the external power supply, then determine whether the power supply state of the external power supply is a power-off state, if the power supply state of the external power supply is the power-off state, further determine whether the battery voltage of the power supply battery 30 is greater than a preset voltage threshold, and if it is determined that the battery voltage of the power supply battery 30 is greater than the preset voltage threshold, it is indicated that the current remaining electric quantity of the power supply battery 30 is greater, and on this basis, after the logic main control unit 10 uploads the target data to the cloud, the communication module 110 may be set to a sleep state.
If the logic main control unit determines that the power supply state of the external power supply is the power-off state and the battery voltage of the power supply battery is not greater than the preset voltage threshold, it indicates that the residual electric quantity of the power supply battery 30 is small, and for this purpose, after the logic main control unit 10 uploads the target data to the cloud, the communication module 110 can be controlled to stop working, so that the power consumption of the data acquisition device is further reduced and the endurance of the data acquisition device is improved.
It should be noted that, after the communication module 110 is controlled to stop working, the logic main control unit 10 may assume that the data acquisition is performed subsequently, and then the target data obtained by the subsequent data acquisition may be stored in the memory or the cache of the logic main control unit 10, so that after the external power supply of the data acquisition device is restored, the logic main control unit 10 may control the communication module 110 to work again, so that the target data stored in the memory or the cache is uploaded to the cloud through the communication module 110.
In addition, in the case that the logic main control unit 10 and the communication module 110 are in the sleep state, the communication module 110 and the logic main control unit 10 can be awakened by sending the awakening information through the cloud, or an interval time is set, and the communication module and the logic main control unit 10 are automatically awakened after the interval time.
In an alternative implementation manner of this embodiment, after the logic master control unit 10 controls the power of the acquisition master control unit 20 to be turned on, in addition to sending a data acquisition instruction, in order to ensure that the acquisition master control unit 20 completes the initialization operation, the logic master control unit 10 may also send a heartbeat data packet to the acquisition master control unit 20, and after completing the initialization operation, the acquisition master control unit 20 may reply a reply instruction corresponding to the heartbeat data packet, for example, an ACK instruction corresponding to the heartbeat data packet, to the logic master control unit 10, so that the logic master control unit 10 knows that the acquisition master control unit 20 has completed the initialization operation at this time, that is, the acquisition master control unit 20 is ready for sensor data acquisition.
In an alternative implementation manner of this embodiment, the logic main control unit 10 designed in this embodiment may take the sending data acquisition instruction as a timing start point, and after a preset time interval, may control the power supply of the acquisition main control unit 20 to turn on again, and send the second data acquisition instruction to the acquisition main control unit 20.
As another possible implementation manner, the present solution may take, in addition to the data acquisition instruction as a timing start point, a time point for controlling the acquisition main control unit 20 to turn on a power supply as a timing start point, and a time point for sending the heartbeat data packet as a timing start point, which is not limited in this application, and the specific manner may be adaptively adjusted according to actual situations.
In an alternative implementation of the present embodiment, as shown in fig. 4, the data acquisition device may further include a display unit 40, where the display unit 40 may specifically include a power lamp that indicates a power state, a status lamp that indicates an operating state, and a network lamp that indicates a communication state, etc.
The logic main control unit 10 may receive first mode switching information, where the first mode switching information includes switching the data acquisition device to a debug mode, and on the basis of this, the logic main control unit 10 controls the display unit 40 to operate according to the first mode switching information, and opens a debug serial port, so as to switch the data acquisition device to the debug mode. The data acquisition device can output debugging data in the debugging process through the opened debugging serial port, so that a worker can debug the data acquisition device according to the debugging data output by the debugging serial port.
As a possible implementation, in the debug mode, the logic master control unit 10 may turn on peripherals including: debug serial ports, communication serial ports, network communications, display unit control, data storage, external interrupts, and the like.
In an alternative implementation manner of this embodiment, the logic main control unit may further receive second mode switching information, where the second mode switching information includes switching the data acquisition device to the field mode, and on this basis, the logic main control unit 10 controls the display unit 40 to stop working according to the second mode switching information, and closes the debug serial port, so that the data acquisition device is switched to the field mode. The difference between the field mode and the debug mode is that the debug serial port is turned off and the display unit stops working, and then, based on the foregoing example, in the field mode, the logic main control unit 10 may turn on the following peripherals, including: debug serial port, communication serial port, network communication, data storage, external interrupt.
In an optional implementation manner of this embodiment, the first mode switching information and the second mode switching information described above may be obtained through external device transmission, and specifically may be sent through the cloud server to enable the data acquisition device to perform mode switching; the mode switching of the data acquisition device can be realized by stirring the mode switching button on the data acquisition device on site, so that the first mode switching information or the second mode switching information is sent to the logic main control unit 10.
