[0034] The utility model provides a kind of intelligent pressure plate remote monitoring equipment based on double confirmation detection synchronization, such as Figure 1 And Figure 2As shown, the intelligent platen remote monitoring device based on double-confirmation detection synchronization includes:

[0035] The intelligent platen assembly includes a master control module, an optical detection assembly, and a platen body provided with a magnetic induction element and rotatingly arranged, the optical detection assembly switches the light path on and off through the transparent area and the shielding area of the light guide column to detect the platen on-off state signal;

[0036] The guide rail type sensor array is provided with a Hall element array magnetically coupled with the magnetic induction element, and detects the platen induction stroke through non-contact magnetic induction, the magnetic induction boundary of the Hall element is dynamically synchronized with the light path switching boundary of the light guide column;

[0037] The wireless collector is wirelessly connected with the guide rail type sensor array to collect the magnetic induction detection data in real time;

[0038] The platen control device is in communication connection with the intelligent platen assembly and the wireless collector, acquires the on-off state signal of the optical detection assembly and the magnetic induction data of the wireless collector, and is used for double-confirmation state determination;

[0039] The platen management system is in communication connection with the platen control device and is used for system data exchange.

[0040] Based on the above scheme, the on-off state of the platen is determined by the synchronous cooperation of optical detection and magnetic induction detection, that is, the state information of the platen detected by the optical detection assembly and the guide rail sensor array is compared, and double-channel synchronous detection and double-state verification are performed, which effectively avoids the problem that the platen state determination is abnormal and the system is misjudged due to the asynchronous induction signal when different sources are detected, greatly improves the accuracy of platen state determination, and greatly reduces system false alarms;

[0041] Moreover, the optical detection and magnetic induction detection processes are both non-contact, and wireless networking communication can also be achieved, the wireless communication is used to realize real-time acquisition and transmission of remote state information, manual on-site operation is not required, remote accurate control and real-time double-confirmation monitoring of the platen state are realized, manual missed detection and the risk of poor contact existing in traditional electrical contact type detection can be avoided, the double-confirmation detection induction signal is synchronous and cooperative, the detection means is effective and reliable, and the accuracy of platen state detection is greatly improved.

[0042] It should be noted that the guide rail type sensor array can be installed above or below the platen, the guide rail type sensor array is fixed on the protection control screen by double-sided adhesive tape or back adhesive, the installation method is convenient, easy to disassemble and self-adaptive adjustment, and the installation stability of the guide rail type sensor array can be ensured, which helps to improve the accuracy of magnetic induction detection of the platen.

[0043] The working process of the intelligent platen remote monitoring device based on double-confirmation detection synchronization is roughly as follows:

[0044] When the platen is remotely controlled to be put in or taken out by the platen management system, the optical detection assembly and the guide rail type sensor array synchronously and cooperatively detect the current state (put-in state / taken-out state) of the platen, the optical detection assembly transmits the detected current state of the platen to the platen control device, the wireless collector keeps wireless communication with the guide rail type sensor array, the wireless collector collects the current state information of the platen detected by the guide rail type sensor array, the wireless collector transmits the collected current state information of the platen to the platen control device, the current state information of the platen detected by the optical detection assembly is consistent with the current state information of the platen detected by the guide rail type sensor array, the platen control device is used for processing the critical state synchronization of the optical detection and the magnetic induction detection of the platen, and the comparison result is summarized to the platen management system for data interaction, the platen management system displays the current state information of the platen in real time, and the advanced application of the platen and the intelligent remote monitoring management of the platen are realized through the platen management system software.

[0045] As shown in the figure b of the drawings in the Figure 4 , when the platen is converted between put-in and taken-out, the magnetic induction piece sweeps the sensing stroke S1 to trigger the sensing boundary of the magnetic induction switch and the guide light column rotates the angle θ1 to trigger the light path switching boundary synchronization, at this time, the linear mapping relationship S1=X·tanθ1 is met;

[0046] As shown in the figure c of the drawings in the Figure 4 , when the platen is completely converted to the taken-out state, the magnetic induction piece sweeps the sensing stroke S2 and the guide light column rotates the angle θ2, the magnetic induction switch cannot sense the magnetic signal, and the optical detection assembly cannot detect the light signal, at this time, the linear mapping relationship S2=X·tanθ2 is met;

[0047] Wherein, X is the vertical height of the magnetic induction piece to the magnetic induction switch (as shown in the figure b and the figure c of the drawings in the Figure 4 ), tanθ is the tangent value, corresponding to the ratio of the sensing stroke S to the vertical height X of the magnetic induction piece to the magnetic induction switch, when the platen is rotated to the critical position, the magnetic field sensing boundary of the magnetic induction switch and the light path switching boundary of the guide light column synchronously trigger the signal jump.

[0048] The optical detection process and the magnetic induction detection process detect the state of the pressing plate in a non-contact manner. The magnetic induction part includes a magnetic steel, and the magnetic induction switch includes a Hall element. In the input state, the magnetic steel is close to the Hall element and makes the Hall element in the on state under the action of the magnetic field. In the exit state, the magnetic steel is away from the Hall element, and the Hall element is in the off state. The optical detection assembly includes a light emitter and a light receiver. The pressing plate body includes a rotating light guide column. The light guide column is provided with a transparent area and a shielding area. The light path is switched and controlled to be on or off through the transparent area and the shielding area to identify the rotation angle of the pressing plate. That is, the light path between the light emitter and the light receiver is controlled to be on or off when the light guide column rotates, thereby realizing the identification of the rotation angle of the pressing plate.

[0049] The optical detection process and the magnetic induction detection process detect the state of the pressing plate in a non-contact manner. The magnetic induction part includes a magnetic steel, and the magnetic induction switch includes a Hall element. In the input state, the magnetic steel is close to the Hall element and makes the Hall element in the on state under the action of the magnetic field. In the exit state, the magnetic steel is away from the Hall element, and the Hall element is in the off state. The optical detection assembly includes a light emitter and a light receiver. The light emitter and the light receiver are arranged on both sides of the light guide column and are symmetrically distributed about the axis of the light guide column. The pressing plate body includes a rotating light guide column. The light guide column is provided with a transparent area and a shielding area. The transparent area and the shielding area of the light guide column switch and control the on or off of the light path to detect the input and exit state signal of the pressing plate.

[0050] The magnetic steel is installed on the handle of the pressing plate body through a structural accessory and rotates with the pressing plate body. Through the magnetic induction cooperation between the magnetic steel and the Hall element, the state of the pressing plate is detected in real time in the magnetic induction detection process, so that the pressing plate can be accurately detected when it is in the input and exit positions. The induction distance between the magnetic steel and the Hall element is D, and the range of D is 0<D≤2mm. That is, when the magnetic field induction between the magnetic steel and the Hall element is maximum, the magnetic steel can trigger the induction signal of the Hall element within a distance of ≤2mm, so as to ensure that the magnetic induction detection of the pressing plate can be effectively and stably performed. The value of the distance D can be set according to actual needs. For example, the distance D can be set to 0.25mm, 0.5mm, 0.75mm, 1mm, 1.25mm, 1.5mm, 1.75mm, 2mm, etc.

[0051] The light guide column is synchronous with the entering angle / exit angle of the pressing plate when the pressing plate body rotates, and the transparent area and the shielding area of the light guide column control the on-off of the light path between the light emitter and the light receiver, that is, the light path between the light emitter and the light receiver is disconnected or kept in communication through the transparent area and the shielding area when the light guide column rotates, so as to realize the optical detection of the exit state and the entering state of the pressing plate. The rotation of the light guide column is synchronous with the rotation of the magnetic steel along with the handle of the pressing plate body. When the pressing plate rotates to the entering state, the rotation angle information of the light guide column detected by the light emitter and the light receiver is synchronous with the magnetic induction signal of the magnetic steel detected by the Hall element, and the detection of different sources is synchronous through non-contact detection and under the judgment of double confirmation, so as to accurately determine the state of the pressing plate.

[0052] In order to conveniently control the on-off of the light path between the light emitter and the light receiver, the structure of the light guide column is divided into transparent and opaque, so that the on-off of the optical signal can be realized through the structure of the light guide column itself, without additional structure, which is convenient for saving materials and structural design. The light guide column is divided into a transparent area on one side and a shielding area on the other side along the rotation axis, the shielding area is provided with a clamping groove type light shield, and the light emitter and the light receiver are arranged on the two sides of the light guide column.

[0053] In this way, when the light guide column rotates, the on-off of the light path between the light emitter and the light receiver is realized through the transparent area and the shielding area. The optical axis of the light path between the light emitter and the light receiver is arranged in a vertical state with the axis of the light guide column, so that when the pressing plate body rotates to the entering or exiting position, the detection accuracy of the rotation angle of the light guide column by the light emitter and the light receiver can be improved, and then the entering state and the exiting state of the pressing plate can be accurately detected.

[0054] The light guide column can be made of transparent material, and a clamping groove is arranged on the other side opposite to the transparent area and a light shield is arranged in the clamping groove, so as to form the shielding area. The light shield can disconnect the light emitted by the light emitter, so that the light receiver cannot receive the optical signal. The shielding area can also be formed by a light shielding patch pasted on the other side opposite to the transparent area, and the sensing boundary of the light shielding patch corresponds to the sensing boundary of the magnetic steel, so as to realize synchronous and cooperative detection.

[0055] The light emitter and the light receiver can adopt an infrared light emitter and an infrared light receiver, or a laser receiver; and the optical detection assembly can also adopt other photoelectric detection devices.

[0056] Specifically, the angle range corresponding to the arc length of the shielding area is θ2-θ1<α<180°-θ1. When the light guide column rotates by an angle θ1, the boundary of the shielding area coincides with the light path between the light emitter and the light receiver. The arc length of the shielding area is greater than the arc length corresponding to the angle θ2 minus the arc length corresponding to the angle θ1, which ensures that the light guide column triggers the light signal boundary synchronously when the magnetic steel triggers the magnetic induction boundary. When the boundary of the shielding area triggers the light signal between the infrared light emitter and the infrared light receiver, the angle α corresponding to the arc length of the shielding area is less than 180°-θ1. When the shielding area blocks the light path between the infrared light emitter and the infrared light receiver, the arc length of the shielding area can be as long as possible, which ensures the reliability of the shielding area.

[0057] As shown in Figure 3 and Figure 4 The induction stroke of the magnetic steel and the rotation angle of the light guide column are synchronized in the following manner:

[0058] When switching from the input state to the exit state, the magnetic steel sweeps the induction stroke S1 to trigger the induction boundary of the Hall element to make the Hall element in an open state, and the light guide column rotates by an angle θ1 to trigger the induction boundaries of the light emitter and the light receiver. The light receiver breaks the light signal of the light emitter, wherein the induction stroke S1 corresponds to the rotation angle θ1.

[0059] The magnetic steel sweeps the induction stroke S2, and the light guide column rotates by an angle θ2, so that the pressing plate rotates to the exit state position. The induction stroke S2 corresponds to the rotation angle θ2.

[0060] The optical detection and the magnetic induction detection remain synchronized in the state switching critical point.

[0061] In this way, the correspondence between the rotation angle and the induction stroke ensures the synchronization of the state double confirmation of the magnetic induction detection and the optical detection, and ensures the synchronization and cooperation of the optical detection and the magnetic induction detection of the pressing plate. The state of the pressing plate is double confirmed and determined, which greatly improves the determination accuracy of the state detection of the pressing plate. When the magnetic steel sweeps the induction stroke S1 and the light guide column rotates by an angle θ1, the pressing plate has not yet completely rotated to the exit state position. Therefore, the pressing plate body needs to rotate by a certain stroke until the magnetic steel sweeps the induction stroke S2 and the light guide column rotates by an angle θ2, and then the pressing plate completely rotates to the exit state position. At this time, the Hall element cannot completely sense the magnetic steel signal, and the light emitter cannot completely detect the light signal.

[0062] wherein, Figure 3 a in the above formula is that the pressing plate is in the input state position, the magnetic steel keeps triggering the Hall element, and the Hall element keeps in the on state. Figure 3b is a schematic diagram of the magnetic steel sweeping the sensing stroke S1 when the pressure plate is converted between the put-in state and the exit state. The pressure plate drives the magnetic steel to rotate, and the magnetic steel sweeps the sensing stroke S1. Figure 3 c is a schematic diagram of the pressure plate in the exit state. When the pressure plate is completely rotated to the exit state, the total stroke swept by the magnetic steel is the sensing stroke S2. If the pressure plate is rotated from the exit state to the put-in state, the pressure plate drives the magnetic steel to rotate, and the stroke swept by the magnetic steel is the sensing stroke S2 minus the sensing stroke S1, which triggers the sensing boundary of the Hall element.

[0063] Figure 4 a is a schematic diagram of the pressure plate in the put-in state. The infrared light signal emitted by the light emitter passes through the light guide column, and the light receiver receives the infrared light signal emitted by the light emitter. Figure 4 b is a schematic diagram of the magnetic steel sweeping the sensing stroke S1 corresponding to the rotation angle θ1 of the light guide column when the pressure plate is converted between the put-in state and the exit state. The magnetic steel sweeps the sensing stroke S1 and the light guide column rotates the angle θ1 synchronously. Figure 4 c is a schematic diagram of the magnetic steel sweeping the sensing stroke S2 corresponding to the rotation angle θ2 of the light guide column when the pressure plate is rotated to the exit state. The magnetic steel sweeps the sensing stroke S2 and the light guide column rotates the angle θ2 synchronously.

[0064] It can be understood that when the pressure plate is rotated from the exit state to the put-in state, the magnetic steel needs to be rotated from the exit state. The magnetic steel needs to sweep a stroke of the sensing stroke S2 minus the sensing stroke S1, and then the magnetic steel triggers the sensing boundary of the Hall element. The Hall element is about to sense the magnetic signal of the magnetic steel. The magnetic steel then sweeps the sensing stroke S1, and the pressure plate is rotated to the put-in state. Similarly, the light guide column needs to rotate an angle of the rotation angle θ2 minus the magnetic rotation angle θ1, and then the sensing boundary of the light emitter and the light receiver is triggered. The light emitter emits and the light receiver is about to sense the light signal. The light guide column then rotates the magnetic rotation angle θ1, and the pressure plate is rotated to the put-in state.

[0068] The pressure plate control device executes the following logic:

[0069] When the pressure plate operation is authorized and the magnetic induction detection is consistent with the optical detection, the put-in state / exit state is output.

[0070] When the pressure plate operation is not authorized and the magnetic induction detection is inconsistent with the optical detection, the abnormal state is output and an alarm is given.

[0071] When the pressboard operation is unauthorized and the magnetic induction detection is consistent with the optical detection, the input state / exit state is output and the operation is recorded.

[0072] The state comparison is performed by the pressboard control device to perform double confirmation determination on the state of the pressboard, which greatly improves the detection accuracy of the state of the pressboard.

[0073] The communication between the wireless collector and the pressboard control device adopts a point-to-point short-range wireless communication mode and supports data encryption transmission. The wireless collector is fixed on the side of the protection and control screen in a pasting manner, facilitating centralized collection on the side of the protection and control screen pressboard.

[0075] The non-electric quantity induction principle is adopted, which is not affected by the number and spacing of the pressboard, and realizes online real-time monitoring of the pressboard. The non-contact magnetic induction principle is adopted to realize the collection of the state of the pressboard, and there is no electrical connection with the secondary circuit of the pressboard. The guide rail type sensor adopts a guide rail design, and the sensor can slide left and right on the guide rail body, which is suitable for different pressboard spacing and number and has high applicability.

[0080] A self-checking program is started to be executed in the order of hardware state detection, communication detection and system reset.

[0081] By setting the abnormality processing mechanism, measures can be taken quickly when inconsistency is found, potential accidents are prevented, and the occurrence of safety accidents is reduced.
