Technical Field

Background
In recent years, with the development of industrial automation, it has been a mainstream trend for industrial automation equipment to replace conventional manual work. Therefore, the requirements for the clamp position sensor are also increasing, and the clamp position sensor is mainly applied to an automobile production line for detecting the position of a mechanical arm. Because the clamp position sensor has a certain service life, the reliability of the clamp position sensor is reduced once the service life is exceeded. If the sensor fails, an error signal is sent, and the control terminal sends out an error operation instruction. If the mechanical arm is transferring at this time, the workpiece can drop in the transferring process, thus causing unnecessary property loss. And secondly, the failure of the sensor can also lead to the failure of normal circulation of the whole production line, and once the shutdown is caused, the economic loss is huge.

Detailed Description
At present, the traditional clamp position sensor has low intelligent degree and cannot feed back the conditions of action times, fault information, service life conditions and the like. For example, an existing clamp position sensor adopts an inductance type detection principle to realize in-place detection of an electric clamp. The device is in a switching value type output mode, has single function and only judges whether a target object enters a detection area. The object here is the work object of the clamp.
Summarizing the drawbacks of existing products, include:
1. the counting function is not available, and the action times of the product cannot be obtained, so that the service life of the product is judged.
2. The communication function is not available, and the fault information and the action condition of the product can not be known.
3. For solution integrators and automakers in the automobile industry, robot arm manufacturers and electric clamp manufacturers, once the sensor is installed, the running condition cannot be known remotely, so that the maintenance cost is high.
According to one or more embodiments, a clamp position sensor, as shown in fig. 1, the sensor circuit comprises an LED indication module, an MCU controller, a communication module, an output circuit, a power supply circuit, a detection circuit, and a high frequency oscillation circuit 7. Wherein,,

A power supply circuit: and power is supplied to modules such as an MCU controller, a high-frequency oscillating circuit and the like.
The detection circuit: and detecting the high-frequency oscillation signal, and giving the detected signal to the MCU controller for processing.
High-frequency oscillation circuit: generating high-frequency magnetic field to detect the target object in a non-contact way. When the target object approaches the detection head, the magnetic field energy is attenuated, the magnetic field signal is converted into an electric signal, then detection is carried out, and AD acquisition and action judgment are carried out on the detection head and the MCU controller. Here, the combination of the high-frequency oscillation circuit and the detection circuit realizes the judgment of the clamp action, thereby enabling the MCU to realize the counting operation of the clamp action.
Meanwhile, in order to meet the refreshing and storage of 3,000,000 groups of data, the cost is reduced, and FLASH is adopted to simulate EEPROM for storage. In order to ensure the accuracy of data storage, a sectional storage mode is adopted by analyzing the data characteristics, an address mark is used as a data index, and a multi-point data backup technology is applied to realize reliable data storage and refreshing.
Furthermore, the embodiment of the disclosure can adopt an EEPROM (electrically erasable programmable read-Only memory) or an external EEPROM chip which is built in an MCU (micro control Unit), the EEPROM has high reliability, and can be rewritten for 1,000,000 times at most, each group of data occupies 3 byte addresses, and millions or even tens of thousands of times of data storage can be realized by only traversing the data in an address space of more than ten bytes.
When the MCU detects that the power supply voltage is lower than a certain threshold value, the RC circuit is adopted to reduce the power-down speed of the power supply for storage. Each data refresh storage is not performed.
The communication of the communication circuit is not limited to a single implementation, and may be accessed to the server by a wired or wireless method. Realizing the communication function of the product.
The embodiment of the disclosure has the beneficial effects that the intelligent design is adopted to store and update the real-time action times of the clamp, so that the three-million times of data refreshing storage requirement is met. The clamp position sensor has a communication function, and can upload data such as fault information, action times and the like of the clamp in real time. Thereby judging the running condition and the service life information of the product.

The control terminal sends related instructions to the server and obtains related product information. When the control terminal sends related instructions to the server, the server transmits the instructions to the communication module, and the communication module transmits the instructions to the controller of the product. The controller processes the instruction signal and sends the instruction signal to the communication module, the communication module uploads the related information to the server, and the server sends the related information to the control terminal for display.
