Abstract

The utility model discloses a manual control manipulator, relating to automatic control instrument for industry, which is especially applicable to manual and automatic switching operation control, the memory comprises a latch device used for realizing the undisturbed switch from the automatic operating state to the manual operating state for the operating result value. When the control needs to be modified, the operator can switch from the automatic working state to the manual working state by key broad, meanwhile the key broad and latch are connected, sending an instruction to enable the fixed pointer fix the address, realizing the original control outputs invariable when switching. The device has the advantages that the switch from the automatic operating state to the manual operating state or the switch from the manual operating state to the automatic operating state can be realized without changing the original control output, meanwhile the servo amplifier can be taken place by directly driving the valve.

Description

Manual control operation device

Technical field:

The utility model relates to industrial instrument for automatic control, is specially adapted to manual, blocked operation control automatically.

Background technology:

Present manual control operation device comprises: signal input part, A/D converter, CPU processor, storer, light-emitting diode display, keyboard, controllable silicon follower; Storer comprises: be used to have manual operation and the memory storage of operating two kinds of duty patterns automatically; Be used for signal is carried out the mode standard memory storage of computing.When needs are revised production control or when automatically wild effect appears in control, must control automatically and switch to manual control but can't keep former control output quantity constant.

The utility model content:

The purpose of this utility model is to overcome above-mentioned defective, and a kind of manual control operation device is provided.Its solution is: manual control operation device, comprise: linking to each other with A/D converter is used to import the signal input part of external control signal, be connected with signal input part and CPU processor and be used for signal is become by analog signal conversion the A/D converter of the discernible digital signal of CPU, with keyboard, A/D converter, displays etc. are connected and are used to instruct each equipment work to realize the CPU processor of no disturbance switching between hand automatically, be connected with CPU and be used to the light-emitting diode display that receives the CPU processor signal and show manual control operation device real-time measurement values, link to each other with CPU and to be used for the keyboard of input operation order, link to each other with CPU and to be used to control the controllable silicon controller of external unit, relay is used for the storer of storage signal and operation result.Storer comprises: be used to there is the memory storage that signal is carried out the mode standard of computing; It is characterized in that storer also comprises: being used to lock the operation result Numerical Implementation does not have the latch that disturbance is switched.

Advantage of the present utility model is to realize to operate automatically manual operation or manual operation to be switched and not to change the no disturbance handoff functionality of former control output quantity to automatic operation room, also can replace servoamplifier and directly drive valve.

Description of drawings: accompanying drawing is the utility model structure block diagram.

Embodiment:

Manual control operation device, comprise: linking to each other with A/D converter is used to import the signal input part of external control signal, be connected with signal input part and CPU processor and be used for signal is become by analog signal conversion the A/D converter of the discernible digital signal of CPU, with keyboard, A/D converter, displays etc. are connected and are used to instruct each equipment work to realize the CPU processor of no disturbance switching between hand automatically, be connected with CPU and be used to the light-emitting diode display that receives the CPU processor signal and show manual control operation device real-time measurement values, link to each other with CPU and to be used for the keyboard of input operation order, link to each other with CPU and to be used to control the controllable silicon controller of external unit, relay is used for the storer of storage signal and operation result; Storer comprises: be used to there is the memory storage that signal is carried out the mode standard of computing; It is characterized in that storer also comprises: being used to lock the operation result Numerical Implementation does not have the latch that disturbance is switched.The memory storage of mode standard is communicated with each other with latch means, and the operation result numerical value of mode standard deposits latch in, synchronously reading.When needs are revised production control or the needs correction is broken down in control automatically, operating personnel use keyboard by the CPU processor instruction automatic mode to be switched to the manual work state, connect the connection of keyboard and latch means simultaneously and send instruction, make latch means lock its interior operation result numerical value, thereby realize that former instantaneous output quantity remains unchanged when switching operation modes.During correction by keyboard to CPU processor and latch means input revision directive, this instruction unlocks device simultaneously to the locking of operation result numerical value, shows correction numerical value.

When production control is stablized, need return automatic operation element state, operating personnel use the keyboard inputting switching command that the manual work state is switched to automatic mode.

The utility model adopts the controllable silicon output signal, follow automatic signal or manually output valve directly replace servoamplifier valve controlled.

Claims
