Description

The invention relates to instrumentation and can be used in hydrographic studies. A recording device is known with simultaneous recording of several parameters 1. However, this device cannot be used to register diverse information. The closest in technical essence to the present invention is a recording device containing a recorder of input signals with a mechanism for moving the writing element along the axis of ordinates and the commutator of G2. However, the known device is not. It allows transmitting different signals by one channel and therefore cannot be used for simultaneous recording of speed and depth information on one medium. The purpose of the invention is simultaneous recording of information about the speed and depth of flow on a common carrier. The goal is to achieve that the device is equipped with a position sensor for a squeaking element, a pulse converter and a pulse distributor, and the TOD is made in the form of two keys and an OR element whose inputs are connected to the outputs keys, with the sensor position of the writing element soy; Dinen with echo sounder inputs and pulse distributor, the outputs of which are connected to control inputs of the pulse converter and keys, the information input of the first key is connected to the output of the echo sounder, the second key - with the output of the pulse converter whose input is connected to the output of the velocity meter, and the output OR connected to the recorder input. Figure 1 shows the block diagram of the device for registration; Fig.2time diagrams illustrating the operation of the device. The device. Contains a recorder 1 with independent rt values of input,. parameters by periodically moving the writing element 2 along the ordinate axis, the sensor 3 position of the writing element, switch 4, consisting of keys 5,6 and the element OR 7, the distributor 8 pulses and the time pulse converter 9. The output of the sensor 3 position of the writing element

connected to the inputs of the echo sounder 10 and the distributor 8 pulses. The output of the echo sounder 10 is connected to the information input of the key 5, and the output of the flow rate meter 11 is connected to the time input of the pulse converter 9 (the OUTPUT of which is connected to the key input B. The outputs of the keys are connected through the OR 7 element to the input of the recorder 1. Control inputs of the keys 5 and b and the converters 9 are connected to the corresponding outputs of the distributor 8 pulses.

The device operates as follows. The pulse signal from the sensor 3 of the position of the writing element (Fig. 2a) is fed to the echo sounder 10 and to the distributor 8 pulses.

The pulse distributor converts the input pulse into signals (FIG. 2d, e |), which arrive at the keys and time of the pulse converter. From the speed meter, the signal in the form of a voltage arrives at the time of the pulse converter (Fig. 2d). The time pulse converter converts these two signals into the signals shown in FIG. sends them to the information input of the key 6. The information input of the key 5 receives a signal from the echo sounder in the form (FIG. 2e).

Thus, the signals supplied to the recorder's input consist of a series of consecutive pulses (zero marks and current depth and velocity parameters, which are recorded on 1 | information chip in the form of points using writing element 2. The recording depth and velocity lines represent a number of points whose frequency corresponds to the frequency of rotation of the writing element or a given number of inclusions specified by the pulse distributor.

The proposed device allows the recording of depths and speeds in open streams as a function of time as temporal information for depths and analog information for velocities transmitted over a single channel.

The use of simultaneous recording of two variable parameters, depths and velocities across the channel section allows one to find the elementary flow rate at any measurement point, facilitates the technology of working with hydrological measurements, improves productivity and improves working conditions.
