Abstract
Description
Technical Field
[0001] This invention relates to the field of maintenance and testing technology, and more particularly to a cable testing device. Background Technology
[0002] Cable testing is a crucial step in ensuring the safe and reliable operation of proton therapy systems during installation and maintenance. Traditional testing relies on large, costly specialized instruments, requiring technicians to inspect each cable in complex wiring environments. Testing necessitates collaboration between personnel at both ends via wired communication devices (such as walkie-talkies), and existing instruments, due to their limited interface compatibility (typically supporting only a few connector types), are incompatible with the diverse connectors used in proton therapy systems (such as 23-pin / 12-pin circular connectors, DB9, BNC, etc.), leading to a cumbersome testing process.
[0003] Traditional methods require manual testing of each cable individually, and are limited by poor interface compatibility and reliance on manual communication, resulting in excessively long testing times per test.

The present invention can also be implemented or applied through other different specific embodiments. Various details in this specification can also be modified or changed based on different viewpoints and applications without departing from the spirit of the present invention. In the absence of conflict, the following embodiments and features in the embodiments can be combined with each other.
[0056] It should be noted that the illustrations provided in the following embodiments are only schematic representations of the basic concept of the present invention. The drawings only show the components related to the present invention and are not drawn according to the actual number, shape and size of the components in the actual implementation. In the actual implementation, the form, quantity and proportion of each component can be arbitrarily changed, and the layout of the components may also be more complex.
[0057] In the following description, numerous details are explored to provide a more thorough explanation of embodiments of the invention. However, it will be apparent to those skilled in the art that embodiments of the invention may be practiced without these specific details. In other embodiments, well-known structures and devices are shown in block diagram form rather than in detail to avoid obscuring embodiments of the invention.
[0058] It should be noted that the application scenario of this invention focuses on the testing of cables already laid in the proton therapy equipment site. These cables connect equipment in different rooms through pipes inside the walls and cable trays between rooms, resulting in complex paths. Traditional testing relies on large and expensive instruments, requiring technicians to coordinate operations at both ends via wired communication. Furthermore, due to poor interface compatibility, the process of testing each laid cable individually is extremely cumbersome and time-consuming, severely impacting equipment maintenance efficiency. Currently available testing devices are mainly designed for unlaid cables, lacking a solution specifically addressing the complex site environment and efficient testing of fixed cables.
[0059] Please see Figures 1-3This invention provides a cable testing device, which specifically includes a host 100 and a slave 200. The host 100 is equipped with various types of first connectors 130. The slave 200 is equipped with various types of second connectors 210 corresponding to the first connectors 130 and a prompter 220. The host 100 and the slave 200 are electrically connected via at least one cable under test 400. Both ends of the cable under test 400 are connected to the corresponding types of first connectors 130 and second connectors 210, respectively. The cable under test may include at least two wire cores. In this embodiment, firstly, the host 100 selects one wire core of the cable under test 400 as a common terminal wire core, and electrically connects this common terminal wire core and a non-common terminal wire core of the cable under test 400 to the prompter 220 via the second connector 210. Then, the host 100 applies a test voltage between the common terminal wire core and the selected non-common terminal wire core, thereby forming a test loop. The prompter 220 can issue a prompt signal when the test loop is completed.
[0060] Please see Figure 1 , Figure 3 In one embodiment of the present invention, the indicator 220 may include a plurality of indicator light arrays 221. The indicator light arrays 221 may include a plurality of LED indicators. For each second connector 210, the common terminal conductor of the cable under test 400 can be electrically connected to one end of all the indicator lights via the second connector 210, and multiple non-common terminal conductors can be electrically connected to the other end of their respective indicator lights via the second connector 210. In this embodiment, when the test loop is connected, the corresponding indicator light can be illuminated to provide an indication.
[0061] Please see Figure 1 , Figure 3 In one embodiment of the present invention, the indicator 220 may further include a speaker 222. For each second connector 210, the common terminal of the cable under test 400 can be electrically connected to one end of the speaker 222 through the second connector 210, and multiple non-common terminal terminals can be electrically connected to the other end of the speaker 222 through the second connector 210. In this embodiment, when the test loop is connected, the speaker 222 emits a beeping sound to provide an indication.
[0062] Please see Figure 1 , Figure 3 In one embodiment of the invention, the indicator 220 may further include a selection switch 223. The selection switch 223 may be electrically connected between the second connector 210 and the indicator array 221, and electrically connected between the second connector 210 and the speaker 222. By operating the selection switch 223, one can select either the indicator array 221 or the speaker 222 for prompting, or both can be selected for prompting simultaneously.
[0063] Please see Figure 1, Figure 2 In one embodiment of the present invention, the host 100 serves as the core control unit of the cable testing device, and may include a main controller 110, a power supply 120, and multiple first connectors 130. The main controller 110 may be an embedded microcontroller chip, such as an ATMEGA16L-8AU microcontroller chip. The output of the power supply 120 is electrically connected to the main controller 110, and it can be used to supply power to the main controller 110. Specifically, the power supply 120 may be a rechargeable lithium battery pack, with its positive output terminal directly connected to the power input pin of the main controller 110 via a wire, and its negative output terminal connected to the ground pin of the main controller 110, providing stable DC operating power to the main controller 110. After receiving power from the power supply 120, the main controller 110 can start its internal program and execute various logic control functions for cable testing. The input of each first connector 130 is electrically connected to the main controller 110.
[0064] In one embodiment of the present invention, the type of the first connector 130 may include, but is not limited to, a 23-pin circular connector, a 12-pin circular connector, a 4-pin circular connector, a DB9 rectangular connector, a BNC connector, an RJ45 connector, and a terminal block, and each type of connector is provided with a corresponding male and female socket, thereby covering common cable interfaces of proton therapy systems.
[0065] In this embodiment, each pin (or terminal) of each first connector 130 is connected to a different input / output port of the main controller 110 via wires on an internal printed circuit board. This connection method allows the main controller 110 to independently access and control each pin of each first connector through its ports.
[0066] When one end of the cable under test 400 is inserted into the first connector 130 on the host 100 that matches its interface type, all the wires of the cable under test 400 are electrically connected to the corresponding ports of the main controller 110 through the pins of the first connector 130. The main controller 110 can set the common terminal wires under the control of the test program. Specifically, the main controller 110 by default identifies the wire corresponding to the first pin on the first connector 130 to which the cable under test 400 is connected as the common terminal wire. For example, if the cable under test 400 is a 23-core control cable and is inserted into a 23-pin circular connector female on the host 100, the main controller 110 will set the wire connected to pin number 1 on that connector as the common terminal wire for this test.
[0067] In one embodiment of the present invention, an identification switch is provided next to each first connector 130, and the mechanical contacts of the identification switch are linked to the corresponding slot of the first connector 130. When the cable under test 400 is inserted into the first connector 130, the cable connector automatically presses down the corresponding identification switch. The output terminals of all identification switches are respectively connected to different input pins of the main controller 110. The main controller 110 outputs a 5V detection voltage to each identification switch and automatically determines the type of the currently connected cable by detecting changes in the level signal of the input pin.
[0068] In this embodiment, the main controller 110, through its program logic and hardware circuitry, can connect the common terminal wire core and all other wire cores of the cable under test 400 to the indicator 220 on the slave device 200. Specifically, the main controller 110 configures the output port corresponding to the selected common terminal wire core as a common reference point. Simultaneously, through its port control circuitry, it sets the port corresponding to each of the other non-common terminal wire cores of the cable under test 400 to a state where a test voltage can be applied. The internal circuitry design of the main controller 110 ensures that the signal path of the common terminal wire core ultimately connects to a common input terminal of the indicator 220, while the signal paths of each non-common terminal wire core under test are respectively connected to the other end of the corresponding indicator unit in the indicator.
[0069] In this embodiment, the main controller 110 performs cable testing by applying a test voltage. When a specific non-common terminal conductor needs to be tested, the main controller 110 generates a 5V DC test voltage relative to the common terminal conductor at its output port corresponding to the selected non-common terminal conductor. For example, to test conductor 2, the main controller outputs a +5V voltage at its control port for conductor 2, while the port for the common terminal conductor remains at a reference level. This voltage difference is transmitted to the slave device 200 through conductors 2 and 1 of the cable under test.
[0070] In slave device 200, since the common terminal wire core is already connected to the common terminal of the indicator (such as the cathode of all indicator lights or one end of the speaker), and the non-common terminal wire core to be tested (wire core 2) is connected to the other end of the specific indicator unit corresponding to its number in indicator device 220 (such as the anode of indicator light 2 or the other end of the speaker), when the master controller 110 applies a 5V test voltage between the common terminal wire core and the selected non-common terminal wire core (wire core 2), and wire core 2 itself and the connections at both ends are intact and conductive, a complete current loop is formed. This current loop starts from the voltage output port of the master controller 110, flows through wire core 2 of the cable under test 400, reaches the corresponding indicator unit (such as indicator light 2) of indicator device 220, then flows through the common connection point of indicator device 220, through the common terminal wire core (wire core 1) of cable under test 400, and finally returns to the common terminal reference point of master controller 110, thus forming a closed test loop. The continuity of the test loop directly drives the indicator 200 to generate a corresponding light or sound signal to indicate the continuity status of the tested wire core.
[0071] Please see Figure 1 , Figure 2 In one embodiment of the present invention, the host 100 may further include a first mode switch 140 and a switching switch 150. The first mode switch 140 is a three-position rotary switch, and its output is connected to the mode signal input pin of the main controller 110 via a wire. The first mode switch 140 can be used to generate a first mode switching signal, with the three positions corresponding to switching commands for a first automatic mode, a second automatic mode, and a manual mode, respectively. The switching switch 150 can be electrically connected between the power supply 120 and the first connector 130. The switching switch 150 is a manually operated multiplexer, and its input is directly connected to the output of the power supply 120 via a wire, receiving a 5V DC voltage provided by the power supply 120. The switching switch 150 has multiple outputs, each of which is connected to an independent pin drive circuit of the first connector 130 via printed circuit board wiring. The switching switch 150 responds to external rotation operations, directly corresponding to the selection state of the internal channel of the switching switch.
[0072] In this embodiment, the main controller 110 can enter the first automatic mode, the second automatic mode, or the manual mode according to the first mode switching signal.
[0073] In the first automatic mode, the main controller 110 can select different non-common terminal cores to conduct according to a preset sequence and time interval, thereby performing cable testing on each non-common terminal core in a time interval and sequence. For example, for a 23-core cable, the main controller 110 starts with core 2 and sequentially tests cores 2 and 3 in a loop. The main controller 110 can apply a 5V DC test voltage between the common terminal core and the currently selected single non-common terminal core at a fixed time interval of 1 second. Voltage is applied to only one non-common terminal core at a time, thus forming an independent first test loop. If the core is conducting, current flows through the corresponding indicator light on the indicator 220, illuminating it for 1 second. The operator can observe the indicator light array 221 flashing sequentially in a loop.
[0074] In the second automatic mode, the main controller 110 can simultaneously connect multiple non-common terminal cores in parallel to perform cable testing on multiple non-common terminal cores at the same time. In this mode, the main controller 110 adopts a group testing strategy. First, the non-common terminal cores of the cable under test are divided into two groups: the first group contains all even-numbered cores, and the second group contains all odd-numbered cores. The main controller 110 simultaneously applies a 5V test voltage between the common terminal core and all cores in the first group. At this time, all indicator light arrays 221 connected to even-numbered cores in the indicator 220 light up simultaneously. After completing the first group test, the main controller 110 automatically applies voltage simultaneously between the common terminal core and all cores in the second group. At this time, the indicator light arrays 221 corresponding to the odd-numbered cores light up simultaneously. Thus, it can be seen that the rapid testing of all cores can be completed by a maximum of two simultaneous voltage application operations.
[0075] In manual mode, the main controller 110 disconnects the voltage output path between itself and the pins of the first connector 130. The switch 150 controls the power supply 120 to apply test voltages between the common terminal core and different non-common terminal cores. Specifically, the operator manually rotates the switch 150 to a specific position, such as the position marked with core 3. This mechanical action drives the multiplexer inside the switch 150, physically connecting its input (positive power supply) to the output corresponding to the pin of core 3. Obviously, the 5V output voltage of the power supply 120 is directly applied to the pin of the corresponding core 3 in the first connector 130 through the selected channel of the switch 150. Since the common terminal core (default core 1) always maintains electrical connection to the power supply 120 reference ground (negative), a voltage difference is formed between the common terminal core and core 3. This voltage is transmitted to the slave device 200 through the cable under test. Core 3 carries a positive voltage to the corresponding pin of the second connector 210, while the common terminal core (core 1) provides a return to the negative terminal of the power supply 120.
[0076] On the slave side 200, wire core 3 is connected to the positive terminal of the corresponding numbered indicator array 221 in the indicator 220 and the signal input terminal of the speaker 222. The common terminal wire core is connected to the negative terminal of all indicator arrays 221 and the ground terminal of the speaker 222. When the switch 150 conducts the wire core 3 path, the current flows sequentially from the positive terminal of the power supply 120, the switch 150, the wire core 3 pin of the first connector 130, the wire core 3 of the cable under test 400, the wire core 3 pin of the second connector 210, the indicator 220, the common terminal wire core of the cable under test 400, the wire core 1 pin of the first connector 130, and the negative terminal of the power supply 120, forming a complete third test loop.
[0077] After confirming the on / off status of the current wire core by observing the feedback from the indicator 220, the operator manually rotates the switch 150 to the next target position (e.g., wire core 4). Based on the external rotation, the switch 150 switches the internal path, disconnecting from wire core 3 and connecting the power supply 120 to the corresponding pin channel of wire core 4. This cycle is repeated, with the operator fully manually controlling the test sequence and pace, applying voltage to each wire core and observing the feedback until all non-common terminal wire cores are tested. Throughout the manual mode test, the main controller 110 does not participate in voltage application control.
[0078] Please see Figure 1 In one embodiment of the present invention, the cable testing device may further include a remote control 300. The remote control 300 is independent of the host 100 and may be handheld. The remote control 300 is communicatively connected to the host 100 and can be used to send a second mode switching signal to the host 100. In this embodiment, the host 100 may enter a first automatic mode, a second automatic mode, or a manual mode according to the second mode switching signal. In some embodiments, the remote control 300 may also communicate with the host 100 via a wired connection.
[0079] Please see Figure 1 In one embodiment of the present invention, the remote control 300 may include a second mode switch 310 and a wireless signal transmitter 320. The second mode switch 310 can generate a second mode switching signal in response to external operation. Specifically, the second mode switch 310 is a three-position toggle switch, with the three positions corresponding to a first automatic mode, a second automatic mode, and a manual mode, respectively. The input terminal of the wireless signal transmitter 320 can be electrically connected to the second mode switch 310, and it can be used to transmit the second mode switching signal. Specifically, the output terminal of the second mode switch 310 is directly connected to the digital signal input pin of the wireless signal transmitter 320 via a wire. When the operator toggles the second mode switch 310 to select a mode position, the switch generates a corresponding level signal (e.g., high, medium, and low levels), which is directly sent to the wireless signal transmitter 320 as the second mode switching signal.
[0080] In this embodiment, the wireless signal transmitter 320 internally includes an encoding circuit and a radio frequency (RF) transmission circuit. When the state of the second mode switch 310 changes, the wireless signal transmitter 320 immediately reads the level signal of the input pin and identifies it as a specific mode switching command. The encoding circuit within the wireless signal transmitter 320 converts the level signal into a binary data packet conforming to the communication protocol. This data packet includes an information code that clearly identifies the target mode (first automatic mode, second automatic mode, or manual mode). Subsequently, the RF transmission circuit of the wireless signal transmitter 320 modulates the encapsulated data packet onto a 2.4 GHz carrier frequency and transmits the modulated wireless signal through its built-in antenna.
[0081] Please see Figure 1 In one embodiment of the present invention, the host 100 may further include a wireless signal receiver 160. The wireless signal receiver 160 is communicatively connected to the wireless signal transmitter 320 and can be used to receive the aforementioned second mode switching signal. Specifically, the wireless signal receiver 160 may be designed based on a 2.4GHz communication protocol, and its antenna continuously receives wireless signals in space. When the wireless signal transmitted by the remote control 300 reaches the host 100, the antenna of the wireless signal receiver 160 captures the signal, and its internal radio frequency receiving circuit amplifies, filters, and demodulates the signal to reconstruct the original binary data packet. The decoding circuit of the wireless signal receiver 160 parses the information code in the data packet to identify the specific target mode command corresponding to the second mode switching signal sent by the remote control.
[0082] The data output terminal of the wireless signal receiver 160 is connected to the serial data input pin of the main controller 110 via a serial communication interface (such as UART). The wireless signal receiver 160 transmits the decoded mode command data to the main controller in real time. The main controller continuously monitors the status of the serial data input pin in its firmware. When a valid mode command data packet is received from the wireless signal receiver, the main controller immediately parses the content of the data packet. According to the parsed command content, the main controller 110 performs the corresponding mode switching operation. If the command requires entering the first automatic mode, the main controller 110 will terminate any other mode operations that may be in progress and immediately start the control program of the first automatic mode, beginning to apply test voltages one by one between the common terminal core and the non-common terminal cores in a preset order and time interval (such as 1 second). If the command requires entering the second automatic mode, the main controller 110 starts the control program of the second automatic mode, executes a grouping strategy, and simultaneously applies test voltages between the common terminal core and a group of non-common terminal cores. If the instruction requires entering manual mode, the main controller 110 executes the manual mode initialization program, disconnects its own voltage output control, and allows the operator to manually select the wire core to which voltage is applied via the switch 150.
[0083] Understandably, the entire wireless control process allows operators to remotely switch operating modes from a location far from the host 100 (such as within the same room or an adjacent room) by operating the second mode switch on the remote control panel 300, without needing to directly touch the first mode switch on the host 100. This remote control function based on 2.4GHz wireless communication is suitable for single-person operation scenarios or environments where equipment installation space is limited and the host 100 is inconvenient to directly access, improving the flexibility and convenience of testing operations.
[0084] In summary, this invention provides a cable testing device. By setting up a host unit equipped with multiple types of first connectors and corresponding second connectors and a slave unit with an indicator, it can be compatible with diverse interfaces in proton therapy systems, eliminating the manual adaptation process caused by the single interface in traditional testing. This invention, through the host unit's design of selecting common-end wire cores and forming a test loop with other wire cores, combined with the audible and visual feedback mechanism of the indicator, allows operators to quickly determine the continuity status of wire cores without relying on wired communication equipment, significantly reducing communication costs and operational complexity for both ends. Simultaneously, the host unit achieves batch wire core testing by centrally applying test voltage, effectively solving the problem of low efficiency in traditional manual testing, significantly shortening cable testing time in complex wiring environments, and improving equipment installation and maintenance efficiency.
