本発明は車載用多重伝送装置のプロアモータ制御回路に
関する。DETAILED DESCRIPTION OF THE INVENTION (Technical Field) The present invention relates to a proar motor control circuit for a vehicle-mounted multiplex transmission device.
（従来技術） 第１図は従来のプロアモータ駆動回路図である。(Conventional technology) FIG. 1 is a conventional pro-ar motor drive circuit diagram.
同図において１はマイクロコンピュータ、２．３．４．
５はトランジスタ、６はプロアモータである。In the figure, 1 is a microcomputer, 2.3.4.
5 is a transistor, and 6 is a pro-a motor.

４段階に変化させることができる回路構成となっており
、トランジスタ５のＯＮ状態でプロアモータ６が最高回
転速度となり、トランジスタ２のＯＮ状態で最低回転速
度となる。The 5 drive circuit shown in FIG. 1 has a circuit configuration that can change the rotational speed of the proar motor 6 in four steps. When the transistor 5 is in the ON state, the proarmotor 6 reaches its maximum rotational speed, and when the transistor 2 is in the ON state, the proarmotor 6 reaches its maximum rotational speed. This is the minimum rotation speed.

路が必要となり、回路が複雑となる等の欠点かあった。While the pro motor 6 is operating with transistor 2 ON,
When there is a request to change the rotational speed of the pro-ar motor 6, the change request information is first received by the microcomputer (hereinafter referred to as the microcomputer), and the content of the request is determined. For example, transistor 3 is turned on and transistor 2 is turned off at the same time to obtain a predetermined rotational speed. In other words, the rotation speed was controlled by changing the current flowing through the pro-ammo clock by switching the resistance circuit. Therefore, as the number of control steps for controlling the rotational speed increases, transistor circuits corresponding to the number of control steps are required, resulting in disadvantages such as the complexity of the circuit.

1 is a switch for specifying the speed of the motor, 22 is a transmitting device, 23 is a transmission line, 24 is a receiving device, 25 is an input circuit, 26 is a microconbeater, 28 is a transistor, and 29 is a pro-a motor. The transmitting device 22 reads the state of each switch based on the voltage level of each input terminal 31 to 34, multiplexes the signals, and outputs the multiplexed signals from the transmission line 23. The output data is read into the microcomputer 26 via the input circuit 25 of the receiving device 24, decoded by the microcomputer 26, and stored in a memory within the microcomputer 26 as individual data before multiplexing. The microcomputer 26 constantly executes the process shown in the flowchart of FIG.
A control signal is output according to the data in the memory. Here, the processing procedure of the microcomputer 26 shown in FIG. 3 will be explained.

態を調べる。■ to θ in the figure indicate each step of the flowchart. Now, the counter in the microcomputer 26 is 0, and the switch 21 is set to S.
A case where W3 and 8w3 of the microcomputer 26 are ON will be explained. First, in step (2), 1 is added to the counter and the contents of the counter in (2) are rewritten to 1.The contents of the counter are checked in (2), and since it is 4 or less, the process moves to step (2). It is checked whether swl (2) is ON or not, and since SW1 is OFF, the process moves to the next step (2), and the state of SW2 is checked as before.
ＳＷ２もＯＦＦであるから■ステップの８ｗ３を調べ、

からＯステップでＯＮ信号を出力する。Since SW2 is also OFF, check step 8w3,
Since the SW3 is ON, (2) Check whether the counter contents are 3 or more at Stellaf 0. Since the content of the counter is l, an ON signal is output at O step.

でＯＮ信号が出力される。After the first process is completed, the process returns to the start and the second process starts again in the same manner as described above. In other words, the contents of the counter are added to 2 in ■, and after confirming the contents of the counter in ■, check ON and OFF in the order of SW1, SW2, and SW3, and since SW3 is ON, add the contents of the counter in ■. investigate. Again, the content of the counter is less than 3, so ■

速度で回転することができる。Next, in the third process, the content of the counter becomes 3, the content is confirmed in step ■, and the process moves to O step where it is turned off.
A signal is output and the machine returns to the start. In the fourth process, the content of the counter becomes 4 at ■, and when the counter number 4 is confirmed at O, the content of the counter is cleared and becomes O at ■. Thereafter, based on the determination in the GX ■ step, the process moves to the ■ step, where an ON signal is output. Thereafter, the above-described processing is repeated, and the output signal of the microcomputer 26 becomes the signal shown in FIG. 4(d). The output of the microcomputer 26 is sent to the pro-a motor 29.
It is applied as a 0 control signal to the base of the transistor 28 to control the energization of the blower motor 29 according to the timing shown in FIG. 4(d), so that the blower motor 29 can be rotated at a predetermined speed.

送線を用いたものに応用できる。In the above explanation, the case where SW3 of the switch 21 and the microcomputer 26 is ON is described, but by the same operation as described above, when SWl is ON, the control signal shown in FIG. 4(b) is generated, and when SW2 is ON, the control signal shown in FIG. (C) of the same figure, and when SW4 is ON, the control signal shown in (,) of the same figure is output. In addition, when all the switches 2 are OFF, the OFF signal shown in the figure (,) is generated, and the blower motor 29 is stopped. (Effects of the Invention) As explained above, according to the present invention, the blower motor is controlled by the energization time, so that the blower motor 29 is not driven. The circuit simply turns on and off the power to the motor. Therefore, regardless of the number of switching steps for the specified speed of the motor, only one system is required for the receiving (i) device.Also, changing the specified speed or the number of switching steps can be easily done without affecting the transmission signal. It can be applied to systems that use optical signals or systems that use multiple transmission lines without multiplexing transmission data.
