Description
Technical Field
The invention belongs to the field of data acquisition, and particularly relates to an acquisition device and an acquisition method for reducing the number of constant flow experiment data acquisition systems.
Background
In a constant-flow hydraulic experiment, data acquisition is mainly completed by a sensor and a data acquisition system together. The sensor is used for acquiring information, converting the information into an electric quantity signal according to a certain rule, and then sending the electric quantity signal to a data acquisition system for analysis and processing. In the experimental process, a single sensor cannot meet the requirement generally, and a plurality of sensors are required to operate simultaneously to meet the information acquisition requirement. Because a single data acquisition system has a limited number of sensors that can be connected, multiple data acquisition systems are sometimes required to operate simultaneously, which is expensive and not an economical solution to purchase multiple data acquisition systems.

The invention also provides an operation method for increasing the number of the sensors connected with the data acquisition system to 2N times by using the acquisition device, which comprises the following steps:
for a single acquisition system channel, N switches are required, numbered i (i ═ 1,2, … … N); connecting a certain channel of the acquisition system with adjacent switch off gears, and sequentially connecting all the switch off gears according to the serial number sequence; connecting 2N sensors to two stages of a switch, wherein the number j (i is 1,2, … … 2N) of the sensors is connected with a left on stage of the switch when j is an odd number, and is connected with a right on stage of the switch when j is an even number; when the jth sensor is collected, the int (j/2) switch is shifted, if j is an odd number, the switch shifts left on gear, if j is an even number, the switch shifts right on gear, and the rest switches are all arranged at off positions, and all sensors can be collected after 2N times of collection in sequence.
Compared with the prior art, the invention has the following advantages:
(1) the operation is simple. Under the condition of small quantity of data acquisition systems, the invention avoids the frequent disassembly and reconnection process between the sensor and the data acquisition system, and can complete the switching of the sensor only by toggling the switch;
(2) is economical and cheap. The invention reduces the number of data acquisition systems, can complete the work of a plurality of data acquisition systems only by a small number of data acquisition systems, and reduces the cost for purchasing the data acquisition systems.
