Embodiment approach 1

[0019] Implementation mode 1: the following combination Figure 1-6 This embodiment will be described. Such as Figure 1-6 As shown, the circuit of the electronic multifunctional monitoring described in this embodiment is composed of three parts: a measurement circuit, a storage circuit, and a playback circuit. The measurement circuit includes pressure, vibration, attitude and temperature detection circuits. It is mainly composed of power converter, excitation source, pressure, vibration, temperature sensor, amplifier circuit, A / D converter, single chip microcomputer, memory, clock and so on. The single-chip microcomputer is the core part of the system, which controls the data acquisition, data access, and clock parameter setting of the system. The clock is the heart of the system, and it wakes up the dormant microcontroller regularly to make it work. The storage and playback route is coordinated by the single-chip microcomputer to coordinate the work of each part, perform...

Abstract

The invention discloses an electronic multifunctional monitor, and belongs to the field of oil field measurement. According to the electronic multifunctional monitor, a lower connecting buckle is arranged in the left side of an outer main body sleeve, an inner main body support is fixed in the right side of the outer main body sleeve, the inner main body support is connected with the left side ofa circuit assembly through a cable, and the left side of the inner main body support in the outer main body sleeve is sealed and isolated through a sensor baffle; and the right side of the inner mainbody support is connected with a communication link socket through a cable and inserted into the left side of a battery sealing sleeve, the right side of the battery sealing sleeve is sealed, and an upper link buckle is arranged outside the battery sealing sleeve. The electronic multifunctional monitor is controlled by one same main control circuit, two paths of pressure signals before and after sand blasting, the vibration quantity of a fracturing tool at the moment of fracturing and the change of the temperature in the whole monitoring period can be synchronously collected at the same time during pressure measurement and fracturing, and data can be played back to the same interface through special playback software; and the corresponding relationship among the parameters is visually seen.
