Description

Technical Field

Background

An electrostatic hand ring is a device which is worn on the wrist of a human body and used for discharging the accumulated electrostatic charge of the human body. It can effectively protect the components from the interference of static electricity, and is used for discharging the static electricity of human body. The principle of the antistatic wired wrist strap is that the static electricity of a human body is conducted to the ground through the wrist strap and the grounding wire. When in use, the wrist strap is contacted with skin, and the grounding wire is directly grounded, so that the maximum effect can be exerted. When the antistatic wrist strap is worn, static electricity generated in a human body can be removed quickly and safely, and the grounding wrist strap is the most basic and most commonly used in antistatic equipment. With the gradual advancement of intelligent factories, it is also important to provide static electricity eliminating equipment on the production line stay wire. The electrostatic wrist strap is mainly divided into 2 types, namely a single-channel electrostatic wrist strap and a double-channel electrostatic wrist strap. The single-channel electrostatic bracelet mainly detects wearing conditions through detecting a capacitor. The dual-channel electrostatic bracelet detects wearing conditions mainly by detecting contact resistance.

After the dual channel electrostatic wristband is worn on the arm, the electrostatic alarm observes the resistance of the loop, which consists of one wire, one person, one wristband and the other wire. If any part of the loop is open (open or resistance exceeds a limit), the circuit will enter an alarm state.

It should also be appreciated that in some embodiments, the terminal device is not a portable communication device, but rather a desktop computer having a touch-sensitive surface (e.g., a touch screen display and/or a touch pad).

In addition, in the description of the present application, the terms "first," "second," and the like are used merely to distinguish between descriptions and are not to be construed as indicating or implying relative importance.

In order to more clearly illustrate the embodiments of the present application or the technical solutions in the prior art, the following description will explain the specific embodiments of the present application with reference to the accompanying drawings. It is evident that the drawings in the following description are only examples of the application, from which other drawings and other embodiments can be obtained by a person skilled in the art without inventive effort.

The static hand ring and the static alarm are arranged at the places where static is easy to generate and accumulate. For example, the industries of petrochemical, printing, coating, chemical, pharmaceutical and the like play an important role: the device to be detected is grounded by static electricity, and the quality of the static electricity introduced into the ground is detected. When the grounding is bad or disconnected, an audible and visual alarm is generated, and explosion danger caused by static accumulation is prevented. When the wrist strap fails, an audible and visual alarm is generated, and the occurrence of electrostatic accidents is prevented.

Under the normal operating state of the static bracelet, the static bracelet alarm can intelligently detect static electricity and resistance in a body, and when the accumulated charge in the body exceeds a certain value, the static bracelet alarm discharges. Specifically, after a dual channel electrostatic wristband is worn on an arm, the electrostatic alarm observes the resistance of a loop consisting of one wire, one person, one wristband and the other. If any part of the loop is open (open or resistance exceeds a limit), the circuit will enter an alarm state. However, in practical use, the electrostatic wristband alarm may be abnormally alarmed because the wearer temporarily does not use the electrostatic wristband, including when the wearer temporarily leaves the station, the electrical connection between the person (wristband) or ground (ground line) is opened (disconnected).

In the prior art, how to deal with this kind of situation. The following solutions exist:

the first is to turn off the power supply. And the second is to take down the electrostatic hand ring, and the default electrostatic alarm is started, and the electrostatic hand ring is not inserted for alarming.

The solution measures lead to the secondary use of the user, and the power supply is easy to be leaked or the electrostatic wristband is easy to be leaked and inserted, and a certain safety risk still exists.

In another solution, a human body detection module is added on the electrostatic alarm, the alarm starts to work when the existence of a human body is detected, and the alarm does not alarm when the existence of the human body is not detected. This solution, while solving most of the problems, also brings new problems. 1. When the user passes in front of the alarm, the alarm is misreported when the user is not wearing the alarm. 2. Most use distance detection, and false positives if there is an occlusion. 3. The electrostatic alarm has limited coverage, and when a user intentionally avoids the FOV (detection range) of the alarm, the alarm does not alarm. A more accurate detection method is needed to determine whether the human body is wearing an electrostatic wristband.

In order to avoid the technical problems, the application adds a sensor on the static hand ring to detect whether the human body is worn or not based on the prior alarm. The scheme of the application detects whether a human body wears the device or not through the proximity sensor.

Referring to fig. 1 of the specification, the dual-channel electrostatic wristband provided by the application comprises:

A bracelet body 1, a first metal contact 2, a second metal contact 3 and a sensor module 4;

And the sensor module sends a first control signal to the electrostatic alarm when detecting that the double-channel electrostatic bracelet is not worn by a wearer so as to control the electrostatic alarm to enter a standby state.

And when the sensor module detects that the double-channel electrostatic bracelet is worn by a wearer, sending a second control signal to the electrostatic alarm, and releasing the standby state of the electrostatic alarm.

The static bracelet is used as equipment worn on a human body, and the human body is connected with the ground through a conductive material, so that static electricity is discharged. When a human body moves, static electricity generated by friction and the like can be quickly conducted to the ground through the static hand ring, so that the accumulation of the static electricity is avoided. However, during actual use, the electrostatic wristband may also limit the wearer's range of motion to some extent. The user may leave the work area temporarily, such as going to a toilet, to another station, etc. In these cases, the user may take off the electrostatic wristband, causing the electrostatic alarm to sound an abnormal alarm. The two-channel electrostatic wristband provided by the embodiment fully considers the actual demands of users in design. Whether the bracelet is worn by a wearer is detected by designing a sensing module on the bracelet. When the user wears the static bracelet, the bracelet can automatically establish connection with the static alarm, and real-time monitoring of static is ensured. When the user removes the electrostatic hand ring, the electrostatic alarm can enter a standby state, so that false alarm is avoided. The design not only solves the problem when the user temporarily leaves the working area, but also greatly improves the accuracy and reliability of static monitoring.

Embodiment one of the present embodiment:

The sensor module is a proximity sensor, and specifically comprises: capacitive proximity sensors, ultrasonic proximity sensors, and photoelectric proximity sensors.

The proximity sensor is also used for generating any one of the following signal fluctuation when a target leaves or approaches. Comprising the following steps: capacitance change signal, acoustic wave reflection signal, optical reflection signal.

The proximity sensor is further used for outputting the first control signal or the second control signal after the signal fluctuation is generated and sending the first control signal or the second control signal to the electrostatic alarm.

Specifically, the capacitive proximity sensor principle: when the target enters the sensing region, the capacitance of the two plates increases, causing the oscillator amplitude to change, thereby changing the schmitt trigger state and producing an output signal.

Photoelectric proximity sensor principle: all photosensors are composed of several basic components: each sensor has an emitter light source (light emitting diode, laser diode), a photodiode or phototransistor receiver for detecting the emitted light, and auxiliary electronics for amplifying the receiver signal.

Photoelectric proximity sensors are mainly of three types: reflective, correlation, and diffuse. When light emitted from the sensor is reflected back at the photo receiver, the reflective proximity sensor detects the object. An object is detected by an correlation sensor when the object breaks the beam between the sensor's transmitter and receiver.

Ultrasonic proximity sensor principle: ultrasonic diffuse proximity sensors employ acoustic wave sensors that emit a series of acoustic wave pulses and then listen for their return sound from a reflecting target. Upon receipt of the reflected signal, the sensor sends an output signal to the control device.

Ultrasonic reflectance sensors can detect objects within a specified sensing distance by measuring travel time. The sensor emits a series of acoustic pulses that bounce off a fixed opposing reflector (any flat hard surface, a machine, a plate). The sound wave must return to the sensor within a user-adjusted time interval. If not, it is considered that there is an object blocking the sensing path and the sensor sends out an output signal accordingly.

Preferably, the sensor module is further configured to generate the signal fluctuation when it is detected that the dual-channel electrostatic wristband is not worn by the wearer (when the dual-channel electrostatic wristband is detached from the wrist), and send a first control signal to the electrostatic alarm so as to control the electrostatic alarm to enter a standby state.

In the standby state, the dual-channel electrostatic bracelet does not conduct static electricity and collect voltage data, and the electrostatic alarm does not send out an alarm.

The sensor module is further used for generating signal fluctuation when detecting that the double-channel electrostatic bracelet is being worn (re-worn), sending a second control signal to the electrostatic alarm and relieving the standby state of the electrostatic alarm.

Implementation manner of the second embodiment is as follows:

The sensor module is a PPG sensor. Specifically, PPG (photoplethysmographic, photoplethysmography) is based on an LED light source and detector to measure the attenuated light after reflection and absorption by the blood vessels and tissues of the human body, record the pulse condition of the blood vessels and measure the pulse wave.

The PPG sensor is also used for acquiring the heart rate of the wearer by using photoplethysmography technology. If the heart rate of the wearer is collected to disappear, judging that the double-channel electrostatic bracelet is not worn by the wearer; and if the heart rate of the wearer is acquired, judging that the double-channel electrostatic bracelet is being worn by the wearer. When the heart rate of the wearer disappears or the heart rate of the wearer appears, the first control signal or the second control signal is output and sent to the electrostatic alarm.

More preferably, the PPG sensor consists essentially of: LED, PD (photodiode) and AFE (analog front end). The devices that contact the skin are mainly LEDs and PDs. Under normal conditions, the alarm of the production line is always in a power-on state. And continuously detecting the grounding state, and alarming when the grounding is bad. The static bracelet also inserts in the alarm always, and when the user began wearing the static bracelet, PPG module detected the PPG signal and in synchronous the alarm through the connector this moment, the alarm began detecting human ground resistance this moment. And alarming if the threshold value is exceeded, and working normally if the threshold value is within the threshold value range. When the user leaves, the PPG module can not obtain a signal when detecting air, and the signal is synchronized into the alarm through the connector to inform the alarm that the alarm is not used, and the alarm does not detect and alarm the electrostatic ring resistor.

In other implementations of this embodiment, the sensor module is further configured to perform a heart rate health determination on the wearer, and send a prompt signal to the electrostatic alarm when it is determined that the heart rate of the wearer is abnormal. Specifically, the PPG signal may obtain a lot of information, for example, it is detected that the user tired causes abnormal heart rhythm, and at this time, the user may be reminded to rest. In addition, the current emotion of the user can be detected, and if the current emotion of the user is detected to be low, special attention is paid so as not to influence the yield and consistency of the production line.

Implementation III of this example: the sensor module is a multi-axis sensor, and specifically comprises: 3-axis sensor, 6-axis sensor, 9-axis sensor. In particular, so-called multi-axis sensors are generally referred to as: accelerometer (ACCELEROMETER), gyroscope (GYROSCOPE), electronic COMPASS (COMPASS), three types of sensors. The three types of sensor measurement data mentioned above are similar to the spatial force decomposition which is learned in middle school physics, and can be decomposed into a spatial coordinate system: x, Y, Z data for three axes (differing in direction, some radial to the axis, some rotational to the axis). Thus, these 3 types of sensors may also be referred to as: a 3-axis accelerometer, a 3-axis gyroscope and a 3-axis electronic compass. This is also known as a 3-axis sensor.

6-Axis sensor: is typically composed of multiple 3-axis sensors, with 2 combinations, 3-axis accelerometers+3-axis gyroscopes. The 3-axis accelerometer and the 3-axis electronic compass are also commonly used for somatosensory games, smart phones and the like.

The multi-axis sensor is also used for detecting the relative micro-movement amount between the wearer and the dual-channel electrostatic bracelet. And if the micro-movement amount is within the normal micro-movement threshold range, judging that the dual-channel electrostatic bracelet is being worn by the wearer. And if the micro-movement amount exceeds the normal micro-movement threshold range, judging that the dual-channel electrostatic bracelet is not worn by the wearer.

The sensor module is further used for outputting the first control signal or the second control signal and sending the first control signal or the second control signal to the electrostatic alarm when the micro-movement amount exceeds or returns to a normal micro-movement threshold range.

Preferably, the 3-axis sensor is preferred, and the cost is low. The acceleration values in the X, Y and Z,3 directions can be detected. The acceleration values in the three directions of rest X Y Z are almost unchanged and the number is low. When a user wears the three-axis sensor, a mems process is adopted in the sensor, so that micro-movement can be detected, and whether the user uses the sensor can be fed back quickly. On the basis, whether the user wears the electrostatic bracelet or not is judged by setting a threshold value.

In addition, since the current universal plug is 4-wire, no redundant PIN is given to the I2C, so that the alarm can be notified only through an interrupt signal.

The 3-axis or 6-axis sensor supplies power, and electricity is taken from the alarm through the electrostatic bracelet plug, so that the cost and the size are reduced. Or, the battery is arranged in the static bracelet and can independently supply power for detecting the wearing of a user and transmitting the signal to the alarm through a wire or a wireless.

The 3-axis sensor is further used for sending a first control signal to the electrostatic alarm when receiving the interrupt signal so as to control the electrostatic alarm to enter a standby state.

And the 3-axis sensor is also used for sending a second control signal to the electrostatic alarm when the receiving of the interrupt signal is stopped, and releasing the standby state of the electrostatic alarm.

Preferably, the first metal contact and the second metal contact further comprise a current limiting resistor with a certain size, so as to protect the safety of a wearer.

A fixing member. The conductive component is used for contacting the conductive component with a wearer so that the conductive component conducts static electricity and collects voltage data for the wearer.

Wherein, R2 is a dual-channel electrostatic bracelet, and the circuit shown in FIG. 2 calculates the resistance R2 connected with the dual-channel electrostatic bracelet, namely the skin impedance of the human body by measuring the value of the voltage U1 and the value of the reference resistance R1.

Preferably, the bracelet body 1, i.e. the fixing part, is generally a wristband, comprising parts such as conductive elastic bands, movable snap fasteners, spring PU wires, protection resistors and the like. The type is divided into a rope wrist strap, a cordless wrist strap and an intelligent anti-static wrist strap, a single-loop wrist strap is used by matching with a single-channel static wrist strap, a double-loop wrist strap is used by matching with a double-channel static wrist strap, the inner layer of the elastic band is woven by conductive yarns, and the outer layer of the elastic band is woven by common yarns. The principle of the wrist strap is to conduct the static electricity of the human body to the ground through the wrist strap and the grounding wire. When in use, the wrist strap is contacted with skin, and the grounding wire is ensured to be directly grounded.

The connecting assembly comprises a connecting wire, a plug, crocodile clips and the like, and is connected with the double-channel electrostatic bracelet and the electrostatic alarm. The two connector lugs of connecting wire subassembly are connected two metal contacts of binary channels static bracelet respectively. The plug of the connecting component is used for being inserted into the connecting socket of the electrostatic alarm. Specifically, the definition of the dual-channel electrostatic bracelet plug is shown in fig. 3.

The electrostatic alarm specifically comprises: the alarm comprises an alarm host, a power adapter, a ground wire and an electrostatic bracelet jack. When the electrostatic alarm works normally, workers can be reminded to check and improve the electrostatic grounding condition in time, accidents caused by static electricity are prevented, and accidents such as fire and explosion are avoided.

Another embodiment of the dual-channel electrostatic wristband alarm system of the application is based on the above embodiment:

The electrostatic alarm is also used for receiving the control signal sent by the sensor module and realizing the switching between the working state and the standby state.

More preferably, the sensor module is further configured to send a first control signal to the electrostatic alarm to control the electrostatic alarm to enter a standby state when it is detected that the dual-channel electrostatic wristband is not worn by the wearer.

And in the standby state, the two-channel electrostatic bracelet does not collect voltage data, and the electrostatic alarm does not give an alarm.

The sensor module is further used for sending a second control signal to the electrostatic alarm when the dual-channel electrostatic bracelet is detected to be worn by a wearer, and releasing the standby state of the electrostatic alarm.

And S200, when the dual-channel electrostatic bracelet is detected not to be worn by a wearer, a first control signal is sent to the electrostatic alarm so as to control the electrostatic alarm to enter a standby state.
