Description
Technical Field
[0001] The present invention relates to the technical field of electronic equipment protection, and in particular to a control method for a station monitor of an adaptive channel. Background Art
[0002] In industrial production, workstation monitors are used to ensure operational safety and product quality. They primarily monitor grounding for wrist straps, table mats, machine equipment, and soldering irons. Existing monitors typically have a fixed number of channels, each dedicated to monitoring a specific type of grounding status. However, this fixed channel setup presents the following problems: First, at different production stages, the number of monitored objects may exceed others, resulting in insufficient channels for those with more objects to monitor, while channels with fewer objects may remain idle. Second, the fixed channel setup cannot be flexibly adjusted to meet actual needs, reducing monitoring efficiency. Two approaches are commonly used in the prior art to address these issues. The first approach allows certain channels to switch between different monitoring objects to improve channel utilization. The second approach implements multi-purpose monitoring by integrating different functional modules into the workstation monitor. The first approach has the disadvantage that switching between the designated monitoring objects can only be performed for certain channels; it cannot be performed for all channels. The second approach also suffers from complex on-site implementation and high replacement costs. Therefore, there is a need to improve the control methods of existing workstation monitors. Summary of the Invention

[0022] The technical solutions of the present invention are described clearly and completely below through examples. It is obvious that the examples described are only some examples of the present invention, not all examples. All other examples derived by persons of ordinary skill in the art based on the examples of the present invention without creative effort are within the scope of protection of the present invention.
[0023] The method for controlling a station monitor of an adaptive channel of the present invention comprises the following steps: S1. Set up a variety of different product external interfaces on each channel of the monitor for connecting different types of detection objects; the product external interfaces may include a wrist strap grounding module, a device grounding module, and a table mat grounding module; the corresponding hardware circuits are as follows: Figure 6-Figure 7 As shown, different interface circuits have different ground pins, such as Figure 6As shown in the figure, the grounding pin of the wrist strap grounding module is pin 7. Figure 7 As shown in the figure, the ground pin of the mat grounding module is pin 5, and a 10K resistor is connected to pin 5, as shown in the figure. Figure 8 As shown in FIG, the ground pin of the device ground module is pin 2, and a 10K resistor is connected to pin 2.
[0024] S2. The monitor has a built-in controller, which is used to automatically identify the interface type of the external product connected to each channel, automatically select the test module, and automatically record the data. The monitor has a built-in channel identification module. When a product is connected to the external interface, it automatically identifies the type of the connected product based on the interface signal. Specifically, the channel identification module can determine the type of product connected to the external interface based on the duration of the high and low levels of the interface signal. Figure 2 As shown in the figure, the duration of the high and low points of the signals input from the three write pins of Channel 1 (including the WR1_1 write pin, WR1_2 write pin, and WAG1 write pin), Channel 2 (including the WR2_1 write pin, WR2_2 write pin, and WAG2 write pin), Channel 3 (including the WR3_1 write pin, WR3_2 write pin, and WAG3 write pin), or Channel 4 (including the WR4_1 write pin, WR4_2 write pin, and WAG4 write pin) can be used to determine the type of product connected to the external interface and output the corresponding signal to the test channel circuit.
[0025] S3, integrate the high resistance test module and the low resistance test module inside the monitor, according to the product category detected by the channel identification module, Figure 3 The switching circuit shown automatically selects to use a high-resistance test module or a low-resistance test module to monitor the product. The circuit switching chip of the switching circuit decides to use a high-resistance test module or a low-resistance test module to detect the product based on the signal transmitted from the channel identification chip of the channel identification module received at the WR1, WR2, WR3 or WR4 pin, and causes S0, S1 and S2 of the circuit switching chip to output corresponding signals, so that the product connected to the product external interface is connected to the corresponding high-resistance test module or low-resistance test module.
[0026] The high resistance test module can be used as follows Figure 4 As shown in the circuit diagram, the low resistance test module can be used Figure 5 As shown in the circuit diagram, the high resistance test module is used to test the ground resistance of the wristband module and the table mat, and then monitor their electrostatic discharge performance. The low resistance test module is used to test the ground resistance of the equipment ground, and then monitor its electrostatic discharge performance. Figure 4 or Figure 5Detect the ground resistance of the product connected to the J1 interface. The controller can automatically read and store the test data.
[0027] like Figure 1 As shown, the adaptive channel workstation monitor of the present invention includes a body, a product external interface 2 is provided on the body, and a controller 1, a high resistance test module 5, a low resistance test module 6 and a switching circuit 4 are provided inside the body.
[0028] The product external interface 2 may include a wrist strap grounding module, a device grounding module, and a table mat grounding module; the corresponding hardware circuits are as follows: Figure 5-Figure 7 As shown, different interface circuits have different ground pins, such as Figure 5 As shown in the figure, the grounding pin of the wrist strap grounding module is pin 7. Figure 6 As shown in the figure, the ground pin of the mat grounding module is pin 5, and a 10K resistor is connected to pin 5, as shown in the figure. Figure 7 As shown in FIG, the ground pin of the device ground module is pin 2, and a 10K resistor is connected to pin 2.
[0029] The controller 1 is used to realize automatic identification of the interface type of the external product connected to each channel, automatic selection of the test module and automatic recording of data.
[0030] Controller 1 is provided with a channel identification module 3, which is used to identify the type of product connected to the product's external interface. Channel identification module 3 includes multiple groups of channel connection ports provided on controller 1. Each group of channel connection ports includes three write pins. The controller determines the type of product connected to the external interface based on the signals input by each write pin.
[0031] Controller 1 can use Figure 1 The control chip shown in the figure has 64 pins. Controller 1 is connected to four channels, each with three write pins. Channel 1 includes WR1_1, WR1_2, and WAG1; Channel 2 includes WR2_1, WR2_2, and WAG2; Channel 3 includes WR3_1, WR3_2, and WAG3; and Channel 4 includes WR4_1, WR4_2, and WAG4. Each channel's corresponding pins also have power and ground terminals. The controller determines the product type connected to the external interface based on the duration of the high and low levels of the signals input to the three write pins of the four channels.
[0032] The switching circuit 4 includes a circuit switching chip, which is electrically connected to the controller 1. The circuit switching chip is provided with signal input interfaces corresponding to different channels, for example, Figure 2The WR1, WR2, WR3, WR4 and OP1 pins shown are input interfaces, and the S0, S1 and S2 pins are output interfaces. The signals output by the S0, S1 and S2 pins are switched between the high and low levels of the three pins and the existing switch circuit to achieve switching between the high resistance test module and the low resistance test module. Figure 4 and Figure 5 The switching circuit is not shown, but it does not affect the understanding of the solution of the present invention by technical personnel.
[0033] The high resistance test module 5 and the low resistance test module 6 are used to monitor the ground resistance of the connected product. The high resistance test module 5 and the low resistance test module 6 can use existing test circuits or can use Figure 3 The high resistance test module shown and Figure 4 The low resistance test module shown.
[0034] Application Example 1 If a wrist strap is connected to a certain channel, the wrist strap grounding module interface is used. After the wrist strap is connected, the monitor obtains a low-level signal from the product interface. The channel identification module analyzes the signal and determines that the connected product is a wrist strap based on the duration of the low level. Because wrist strap monitoring requires the use of a high-resistance test module, the automatic control software in the monitor selects the corresponding test module to test the wrist strap, obtains the resistance parameters of the wrist strap, and automatically saves the parameters.
[0035] Application Example 2 If a machine device is connected to a certain channel, the device grounding module interface is used. After the machine device is connected, the monitor obtains a low-level signal from the product interface. The channel identification module analyzes the signal and determines that the connected product is a machine device based on the duration of the low level. Because the machine device monitoring requires the use of a low-resistance test module, the automatic control software in the monitor selects the corresponding test module to test the machine device, obtains the resistance parameters of the machine device, and automatically saves the parameters.
[0036] Application Example 3 If a table pad is connected to a certain channel, the table pad grounding module interface is used. After the table pad is connected, the monitor obtains a low-level signal from the product interface. The channel identification module analyzes the signal and determines that the connected product is a table pad based on the duration of the low level. Because the table pad monitoring requires the use of a high-resistance test module, the automatic control software in the monitor selects the corresponding test module to test the table pad, obtains the resistance parameters of the table pad, and automatically saves the parameters.
[0037] Application Example 4 If a soldering iron batch machine is connected to a certain channel, the device grounding module interface is used. After the soldering iron batch machine is connected, the monitor obtains a low-level signal from the product interface. The channel identification module analyzes the signal and determines that the connected product is a soldering iron batch machine based on the duration of the low level. Because the soldering iron batch machine monitoring requires the use of a low-resistance test module, the automatic control software in the monitor selects the corresponding test module to test the soldering iron batch machine, obtains the soldering iron batch machine's resistance to ground parameter, and automatically saves the parameter.
[0038] Through the above four application examples, it can be seen that the adaptive channel workstation monitor control method of the present invention can automatically identify the interface category used by the product connected to the channel, automatically identify the product type, and use a high-resistance test module or a low-resistance test module to adaptively monitor the product, which can effectively avoid channel idleness and improve monitoring efficiency; there is no need to frequently replace hardware modules, which can reduce the complexity and cost of on-site implementation; the monitor can flexibly adjust the monitoring object according to actual production needs and adapt to a changing production environment.
