The usual test method is to use a computer to test the driller reader. During the test, the serial port of the computer is connected to the data interface of the driller reader, and the driller reader is tested through a special test program. Since only one reader can be tested at a time during the test Taiwan driller reader, work efficiency is relatively low

Embodiment Construction
[0007] The present invention will be described further in conjunction with accompanying drawing now.
[0008] figure 1 It is a schematic circuit diagram of an embodiment of the present invention. exist figure 1 Among them, 1 is MPU, 2 is RS232, and 3 is a multi-channel analog switch. It can be seen from the drawings in the manual that this multi-channel analog switch is actually a dual 4-channel analog switch, and R1 and R2 are resistors. The P1.0 and P1.1 terminals of MPU 1 are respectively connected to the A0 and A1 terminals of the multi-channel analog switch 3 through resistors R1 and R2, and its TXD and RXD terminals are respectively connected to the T1IN and R1OUT terminals of RS2322, and the T1OUT and R1IN terminals of RS2322 The terminal is connected to the Da and Db terminals of the multi-channel analog switch 3, and the C1+ pin is connected to the C1- pin, C2+ pin and C2-, V+ pin and VCC, and the ground and V- are respectively connected to capacitors, and C1+, C2+,...

A driller reader test device applied for petroleum drilling while-drilling measurement system comprises an MPU, an RS232 and a multi-path analogue switch, wherein the P1.0 and the P1.1 ends of the MPU are respectively connected with the A0 end and the A1 end of the multi-path analogue switch via resistors, while the TXD end and the RXD end are respetively connected with the T1IN end and the R1OUTend of the RS232; the T1OUT end and the R1IN end of the RS232 are connected with the Da end and the Db end of the multi-path analogue switch; the EN end of the multi-path analogue switch is connectedwith +5V, the V+ end is connected with +15V and the V- end is connected with -15V; four port groups of the multi-path analogue switch are respectively connected with a driller reader in test; the MPUprocesses circular tests on the multiple driller readers connected with the multi-path analogue switch. The driller reader test device can test multiple machines synchronously, to improve working efficiency.
Description
technical field [0001] The invention relates to a test device for a driller reader, in particular to a test device for a driller reader used in an oil drilling measurement system while drilling. Background technique [0002] In the measurement-while-drilling system, the driller's reader needs to be tested and maintained. The usual test method is to use a computer to test the driller reader. During the test, the serial port of the computer is connected to the data interface of the driller reader, and the driller reader is tested through a special test program. Since only one reader can be tested at a time during the test Taiwan driller reader, the work efficiency is relatively low. Contents of the invention [0003] In the testing and maintenance of the driller reader, the computer is usually used to test the driller reader. Since only one driller reader can be tested at a time during the test, the work efficiency is relatively low. The purpose of the present invention is ...
