Abstract
The utility model discloses a kind of absolute value signal conversion equipment, including spot sensor（1）, absolute value block（2）, control unit（3）, described spot sensor（1）Output signal and absolute value block（2）Input signal connection；Absolute value block（2）Output signal and control unit（3）Input signal connection, the method for also disclosing absolute value signal conversion simultaneously, absolute value signal is provided by apparatus and method of the present utility model for each occasion of the production scene control unit without the function that takes absolute value to change, to ensure the production normal operation of production scene.
Description
Technical field
The utility model belongs to automatic field, is related to a kind of absolute value signal conversion equipment.
Background technology
Currently in each production scene, automatically control and be more and more applied among the production of reality, but due to
Investment and production such as need at the reason, and part producing scene is not controlled using programmable control system, some
Side, due to special requirement, it is necessary to be used after the collection signal at scene is negated, due to the controller that can not utilize directly
Signal negates function, and the hardware-in-the-loop for causing live many function needs complicated carries out signal conversion, because complex circuit is easy
Situations such as producing failure, makes troubles to production.
Utility model content
Purpose of utility model：A kind of absolute value signal conversion equipment is provided, it is exhausted without taking for each production scene control unit
A kind of absolute value signal conversion equipment and conversion method are provided to the occasion for being worth function, to ensure that the production of production scene is normally transported
OK.
The technical scheme of offer of the present utility model senses for a kind of absolute value signal conversion equipment of offer, including scene
The input signal connection of device, absolute value block, control unit, described spot sensor output signal and absolute value block；Absolutely
The input signal of output signal and control unit to being worth module connects.
Described absolute value block includes negating device and big value selector, and the described device output signal that negates selects with big value
Device input signal connects.
Described control unit is the control unit without the function that takes absolute value.
Described big value selector is also connected with spot sensor output signal.
Compared with the prior art, it is simple raw at some using a kind of absolute value signal conversion equipment of the present utility model
Production scene and less occasion is invested, can be with the case where controller does not possess absolute value algorithm in itself and absolute value negates
Power and energy is carried out using device of the present utility model and computational methods, so as to realize negating for on-site signal absolute value signal,
Invest that small, function is reliable, can be widely applied.
Brief description of the drawings
Fig. 1 is structure drawing of device of the present utility model;
Fig. 2 is absolute value block structure chart of the present utility model.
It is identified as in figure：1st, spot sensor, 2, absolute value block, 3, control unit, 21, negate device, 22, big value selection
Device.
Embodiment
Below in conjunction with the accompanying drawings and utility model is described further specific embodiment：
A kind of absolute value signal conversion equipment, including spot sensor 1, absolute value block 2, control unit 3, negate device
21st, big value selector 22, the output signal of spot sensor 1 are connected with the input signal of absolute value block 2；Absolute value block 2
Output signal is connected with the input signal of control unit 3.
Further absolute value block 2 includes negating device 21 and big value selector 22, it is described negate device output signal with
Big value selector input signal connection, the signal at scene can be negated and selected by negating device and big value selector,
Then qualified parameter is exported.
Further control unit 3 is the control unit without the function that takes absolute value, in the control for not possessing the function that takes absolute value
Unit processed, can solve the function that takes absolute value by device of the present utility model.
Further big value selector is also connected with the output signal of spot sensor 1, is believed by signed magnitude arithmetic(al) for input
Big value is carried out after number negating by big value selector and original signal to select, the absolute value of the output as signal of big value selector
Signal.
According to the technical solution of the utility model, after being attached all parts and module using wire, true
In the case of protection device normal operation, tested according to the following steps：
The first step, utilize the collection site data parameters of spot sensor 1；
Second step, the data parameters collected are input to absolute value block 2；
3rd step, absolute value block 2 carry out signed magnitude arithmetic(al) to the data parameters of input, and export absolute value parameter.
Described signed magnitude arithmetic(al) is to carry out big value by big value selector and original signal after input signal negates to select, greatly
The output of value selector is the absolute value signal of the signal.
It the above is only preferred embodiment of the present utility model, it should be pointed out that：For the ordinary skill people of the art
For member, on the premise of the utility model principle is not departed from, some improvements and modifications can also be made, these improvements and modifications
Also the scope of protection of the utility model should be considered as.
