detailed description

The preferred embodiments are described in detail below with reference to the accompanying drawings. It is to be understood that the following description is only illustrative, and is not intended to limit the scope of the invention.

Example 1

1 is a schematic view showing the connection of an electronic detonator connector provided by the present invention. As shown in Figure 1, the electronic detonator connector includes an upstream port and a downstream port. The upstream module and the downstream module are connected by the surface conductor 2, and the foot line of the electronic detonator 1 is connected in parallel with the surface conductor 2. In general, a control bank module is used to assemble an electronic detonator branch (referred to as a "link" in the present invention). Several electronic detonators are connected to each link.

In Figure 1, the upstream port of the electronic detonator connector is used to access the upstream device. If the electronic detonator connector is the first connector in the link, the upstream port of the first electronic detonator connector is used to access the control module, that is, the upstream device is the control module. If the electronic detonator connector is not the first connector in the link, the upstream port of the electronic detonator connector is used to access the last electronic detonator connector in the link, at which point the upstream device is the last link in the link. Electronic detonator connection. For example, in Figure 1, for the rightmost electronic detonator connector, the upstream device is the electronic detonator connector on the left side, so when the rightmost electronic detonator connector is connected to the link, its upstream port is connected to Electronic detonator connection on the left side.

In Figure 1, the downstream port of the electronic detonator connector is used to access the downstream device. For example, in FIG. 1, for the electronic detonator connector on the left side, the downstream device is the electronic detonator connector on the right side thereof, so the downstream port of the left electronic detonator connector is connected to the electronic detonator connector on the right side thereof. It should be noted that if the electronic detonator connector is the last electronic detonator connector in the link, the downstream port is left blank, that is, no device can be connected.

For easy connection, the upstream and downstream ports can use common standardized interface components such as USB-B or USB-A.

As can be seen from FIG. 1, the above-mentioned electronic detonator connector is used to implement an electronic detonator quick access link. In addition, the electronic detonator connector also implements the communication function between the control module and the electronic detonator. That is, the electronic detonator connector can forward the identification command, the registration command, the patrol command, the detonation command sent by the control platoon module to the electronic detonator, and can transmit the response signal sent by the electronic detonator to the control platoon module. This will be explained in detail in the description of the method embodiment that follows.

1 above shows only one control row module connecting two electronic detonator connectors, it should be clear that FIG. 1 is merely an example for explaining the present embodiment. The control panel module can connect more than two electronic detonator connections.

2 is a schematic view of the connection of an electronic detonator connector with an indicator module. Usually, during the construction process, after installing the electronic detonator connection connected with the structure of FIG. 1 above, the electronic connection is completed. The state of the detonator is unknown to the construction personnel. To overcome this problem, an indicator module indicating the operational status can be added to the electronic detonator connector. As shown in FIG. 2, the indication modules are respectively connected to the upstream port and the downstream port. In the present invention, the electronic detonator connector is passive, i.e., does not provide electrical energy. Because if the component directly connected to the electronic detonator has the ability to provide voltage, this itself is a challenge to the safety of the electronic detonator. And if the electronic detonator connector is passive, it is necessary to solve the power supply problem of the indicator module. In the present invention, the power provided by the control bank module is used to provide energy to the indicator module. The control module communicates with a communication voltage that ensures the intrinsic safety of the electronic detonator. Therefore, when the indication module is respectively connected to the upstream port and the downstream port, the power provided by the control row module can be obtained.

The indicator module is configured to issue a first indication signal after the electronic detonator connector is accessed. A second indication signal is issued after the electronic detonator connector is registered to the control bank module. A third indication signal is issued after the downstream device of the electronic detonator connector is connected to another electronic detonator connector. The indication signal can be any information that is visible, audible, or otherwise perceptible. Also, the indicator module can be a speaker, a vibrator, a light emitting diode, or an electronic display element. For example, when the indication signal is an optical signal and the indication module is a light emitting diode, the first indication signal may be long bright light, the second indication signal may be flashing light, and the third indication signal may be no bright light (diode does not emit light).

When the indication signal is an acoustic signal or an optical signal, it is preferable that the third indication signal is a signal that does not emit sound or does not emit light. This is because, in order to ensure the intrinsic safety of the electronic detonator, the control row module provides the link The communication voltage is relatively low. If each of the connected electronic detonator connections remains audible or illuminating, when there are too many electronic detonator connections in the link, the indicator module of each electronic detonator connection will be consumed. Large currents introduce large noise, which reduces the signal-to-noise ratio of the control panel module's acquisition of electronic detonator response signals. To this end, the indicator module of the previous electronic detonator connection should no longer sound or illuminate (ie, consume no current) when accessing the new electronic detonator connection.

The indication signal will be further described in conjunction with the description of the method below.

The electronic detonator connector provided by the present invention further includes a short circuit protection module connected to the electronic detonator foot line. The short circuit protection module is used to prevent other electronic detonators on the link from being short-circuited when the electronic detonator pin connected to the electronic detonator connector is short-circuited. Due to the structure of the electronic detonator connector, when the connector connected in parallel with the electronic detonator is short-circuited, other electronic detonators on the link may be short-circuited. To prevent this, the short-circuit protection module may be connected in series in the electronic detonator pin. Most simply, the short circuit protection module can be a current limiting resistor R1 (shown in Figure 3).

Figure 3 provides an electronic detonator connector of the present invention including a preferred circuit structure for a display module, and three electronic detonator connections that are ultimately interconnectable through ports are schematically depicted in Figure 3. As shown in FIG. 3, in the electronic detonator connector provided by the present invention, the upstream port includes a surface conductor first terminal S01 and a surface conductor second terminal S02. The downstream port includes a surface conductor third terminal X01 corresponding to the surface conductor first terminal S01 and a surface conductor fourth terminal X02 corresponding to the surface conductor second terminal S02. The first terminal of the surface conductor S01 and the surface conductor third connection The wire terminal X01 is connected by the first wire G01 of the surface wire, and the second wire terminal S01 of the surface wire and the fourth terminal X02 of the surface wire are connected by the second wire G02 of the surface wire.

Further, the upstream port further includes a display module first terminal S03 and a display module second terminal S04. The downstream port further includes a display module third terminal X03 corresponding to the display module first terminal S03 and a display module fourth terminal X04 corresponding to the display module second terminal S04. The display module includes a light emitting diode D, a transistor Q, and a balancing resistor R2. The first terminal S03 of the display module is connected to the second terminal S04 of the display module, the third terminal X03 of the display module is connected to the gate of the transistor Q, and the second terminal S04 of the display module and the fourth terminal of the display module X04 are passed through the surface conductor. The third connection line G03 is connected. One end of the light emitting diode is connected to the second connection line G02 of the surface conductor, and the other end is connected to the source stage of the transistor Q. The drain of the transistor Q is connected to the third connection line G03 of the surface conductor. One end of the balancing resistor R2 is connected to the second connection line G02 of the surface conductor, and the other end is connected to the gate of the transistor Q.

Referring to FIG. 3, the working principle of the display module is as follows: the terminals S03 and S04 of the electronic detonator connector are short-circuited, and when the electronic detonator connector is not connected to the next electronic detonator connector, the terminal S02 (DX-) is at a high level. The terminal S04 is at a low level, the gate voltage of the transistor Q is greater than the turn-on voltage, the transistor Q is turned on, and the light-emitting diode D is bright (corresponding to the first indication signal). When the electronic detonator connector is connected to the next connector, since the gate of the transistor Q5 is pulled low, the gate voltage is 0, the transistor is turned off, and the LED D is not lit (corresponding to the third indication signal). At this point, the newly connected electronic detonator connection The diode D of the piece lights up.

Whether or not the light-emitting diode D is lit is also related to the level state of the terminal S04 and the terminal S02 (DX-). As described above, when the control row module is in the electronic detonator discovery state (the state in which the identification command is sent), the gate of the transistor Q of the current last electronic detonator connector is not short-circuited, and the light-emitting diode D of the last electronic detonator connector The state will be flashed according to the state of the control row module. When the control row module finds and registers the electronic detonator in parallel with the last electronic detonator connector, the LED flashes rapidly for a few seconds (corresponding to the second indication), thereby realizing the registered electronic detonator. Instructions.

In this example, the short circuit of the electronic detonator is not prevented, causing a short circuit of the entire link. The current limiting resistor R1 can also be connected in series in each electronic detonator pin (as shown in Figure 3).

The invention also provides an electronic detonator setting method based on an electronic detonator connector, by which the parameter setting of the electronic detonator can be quickly set. The parameters include an electronic detonator sequence number, an electronic detonator network address, an extension of an electronic detonator (absolute extension or relative delay), and the like.

Example 2

Figure 4 is a generalized step of an electronic detonator setting method based on an electronic detonator connector, comprising:

Step 11: The control row module periodically transmits an identification command.

Step 12: Access an electronic detonator connector and its connected electronic detonator.

Step 13: Determine whether the electronic detonator is registered to the control row module, and if the electronic detonator is not registered to the control row module, register the electronic detonator to the control row module.

Step 14: Repeat the above steps until all electronic detonator connections are accessed.

In the above step, the identification instruction sent by the control row module may include control row module attribute information, and the control row module attribute information is used to assist in determining whether the electronic detonator is registered to the control row module. The control row module attribute information may be a control row module ID (a host ID or a host ID of the control row module), which is a unique number for identifying the identity of the control row module.

Example 3

The specific implementation process of the method provided by the present invention is described below by taking the control row module attribute information as the control row module HostID as an example.

Figure 5 is an embodiment of an electronic detonator setting method based on an electronic detonator connector. As shown in FIG. 5, the method includes:

Step 101: The control row module periodically sends an identification instruction, where the identification instruction includes a control row module HostID.

Step 102: Access an electronic detonator connector.

Step 103: The electronic detonator connector forwards the identification command to the electronic detonator connected in parallel on the electronic detonator connector.

Step 104: If the electronic detonator does not store the control row module HostID, the electronic detonator is not registered to the control row module, and step 106 is performed; if the electronic detonator stores the control row module HostID, the control row module HostID in the identification instruction is extracted.

Step 105: Comparing the control queue module HostID of the electronic detonator storage with the control row module HostID in the extracted identification instruction, if the control array module HostID of the electronic detonator storage is inconsistent with the control row module HostID in the extracted identification instruction, the electronic detonator is not Registering to the control row module, performing step 106; otherwise, the electronic detonator has been registered to the control row module, step 107;

Step 106: Register the electronic detonator to the control row module.

Step 107: Return to step 101 and repeat the above steps until all electronic detonator connections are accessed.

In the above process, it is determined whether the electronic detonator connected to the electronic detonator connector in parallel is registered to the control row module by controlling the row module attribute information. The advantage is that the instruction sent by the control row module (including the identification instruction and the registration instruction described later) is sent in a broadcast manner, so all the electronic detonators of the link of the control control module are connected (via the electronic detonator connection) Incoming) will receive a broadcast command. In the present invention, the electronic detonators are connected to the link one by one through the electronic detonator connection. After the registered one electronic detonator is completed, the next electronic detonator is accessed, and the registered electronic components in the link are The detonator stores the control row module attribute information, which ensures that the electronic detonator that has accessed the link and successfully registered does not respond to the identification command, and only the newly accessed electronic detonator responds to the identification command. Avoid the problem that the control panel module can not interact with information when communicating with more than two electronic detonators. In addition, the new electronic detonator (factory setting) generally does not store the control panel module attribute information, but sometimes it encounters the electronic detonator registered to a control row module through the electronic detonator connector, and the chain of the control row module for various reasons. The path is removed, and the link to which other control row modules belong is accessed. At this time, the electronic detonator has After storing the previous control module attribute information, in order to successfully register to the new control row module, it is necessary to compare the control row module attribute information of the electronic detonator storage with the new control row module attribute information.

In the above method, the electronic detonator registration process of step 106 is actually a process of writing parameters related to the electronic detonator operation (electronic detonator setting parameters) into the electronic detonator. The electronic detonator setting parameters mainly include the electronic detonator sequence number / electronic detonator network address, electronic detonator extension (including absolute delay or relative delay).

Referring now to Figure 6, the electronic detonator sequence number is used as an electronic detonator setting parameter to illustrate the specific process of the method provided by the present invention.

Example 4

Step 201 - Step 204: The same as Step 101 - Step 104 of Embodiment 1 respectively.

Step 205: Comparing the control row module ID of the electronic detonator storage with the control row module ID in the extracted identification instruction. If the control row module ID stored in the electronic detonator is inconsistent with the control row module ID in the extracted identification command, the electronic detonator is not Registering to the control row module, performing step 206; otherwise, the electronic detonator has been registered to the control row module, and step 210 is performed.

Step 206: The electronic detonator sends an acknowledgement signal to the control bank module via the electronic detonator connector. The electronic detonator is an electronic detonator that is accessed through an electronic detonator connection in step 202 (same as step 102).

Step 207: After the control panel receives the signal sent by the electronic detonator, the electronic detonator is determined. The order in the link, the electronic detonator sequence number.

Since the electronic detonators are connected to the control row module one by one through the electronic detonator connector, a counter can be set in the control row module, the initial value is set to 0, and the control row module receives a response signal (representing one connection) The incoming electronic detonator needs to be registered), the counter is incremented by 1, and the counter value is used as the sequence number.

For example, when the control panel module is connected to the first electronic detonator, the counter is 1, the sequence number of the first electronic detonator is 1; when the control panel module is connected to the second electronic detonator, the counter is based on 1. Add 1 and the counter is 2, then the sequence number of the second electronic detonator is 2; and so on.

Step 208: The control row module sends a registration instruction including an electronic detonator sequence number to the electronic detonator via the electronic detonator connector.

Step 209: After receiving the registration instruction, the electronic detonator extracts the sequence number therein and stores it in the electronic detonator.

Step 210: Return to step 201 and repeat the above steps until all electronic detonator connections are accessed.

The above electronic detonator setting parameters may further include an electronic detonator delay. Since the deployment of the electronic detonator is pre-designed, each electronic detonator in each link should be pre-designed for which blasthole at the blasting site, and the blasthole delay is predicted, so the link can be The sequence number corresponds to the delay of the blasthole and is stored in advance in the control row module. In this way, after the electronic detonator is successfully registered and the sequence number is stored, the electronic detonator can be set for the electronic detonator according to the sequence number of the electronic detonator. It has been postponed.

Referring now to Figure 7, the electronic detonator setting parameters including the electronic detonator sequence number and the electronic detonator delay are illustrated to illustrate the specific process of the method provided by the present invention.

Example 5

Step 301 - Step 304: The same as Step 101 - Step 104 of Embodiment 1 respectively.

Step 305: Comparing the control row module ID of the electronic detonator storage with the control row module ID in the extracted identification instruction. If the control row module ID stored in the electronic detonator is inconsistent with the control row module ID in the extracted identification instruction, the electronic detonator is not Registering to the control row module, performing step 306; otherwise, the electronic detonator has been registered to the control row module, and step 309 is performed.

Step 306: The electronic detonator sends an acknowledgement signal to the control bank module via the electronic detonator connector.

Step 307: After receiving the signal sent by the electronic detonator, the control row module determines the order of the electronic detonator in the link, that is, the electronic detonator sequence number.

Then, the electronic detonator delay is determined according to the electronic detonator sequence number previously stored in the control row module and the electronic detonator delay correspondence table.

Figure 8 is a table corresponding to the electronic detonator sequence number and the electronic detonator delay. The electronic detonators in the corresponding order in the link are associated with the delay. When determining the extension, if the control row module determines that the sequence number of the currently accessed electronic detonator is 3, the deferred millisecond corresponding to the sequence number 3 is found from the table, and the sequence number 3 and its corresponding deferred millisecond are stored in the registration. In the instruction, and sent to the electronic detonator.

Step 308: The control bank module sends a registration instruction including the electronic detonator sequence number and the electronic detonator extension to the electronic detonator via the electronic detonator connector.

Step 309: After receiving the registration instruction, the electronic detonator extracts the electronic detonator sequence number and the electronic detonator extension therein and stores them in the electronic detonator.

Step 310: Return to step 301 and repeat the above steps until all electronic detonator connections are accessed.

In the above process, when the electronic detonator is connected to the link and registered, the extension of the electronic detonator can be stored. In fact, after all the electronic detonators are connected to the link, an extension can be set for each electronic detonator by issuing an extension setting command. The process is described with reference to Figure 9, as in Example 6 below.

Example 6

Steps 401 to 410: are the same as steps 201 to 210 of Embodiment 2, respectively.

Step 411: The control row module forms an extension setting instruction including the sequence number and the electronic detonator extension corresponding to the sequence number according to the correspondence relationship between the sequence number stored in advance and the electronic detonator extension.

Step 412: After receiving the electronic detonator extension instruction through the electronic detonator connection, the electronic detonator extracts the sequence number in the extension setting instruction and the electronic detonator extension corresponding to the sequence number;

Step 413: The electronic detonator determines whether the extracted sequence number is consistent with the sequence number stored by itself (stored in step 208 and step 308). If they are consistent, the electronic detonator delay corresponding to the sequence number is stored.

The difference between Embodiment 6 and Embodiment 5 is that in Embodiment 6, the extension of the electronic detonator is at all After the electronic detonator connection access link (ie, all electronic detonator access links) and registration, a deferral is set for each electronic detonator. In the fifth embodiment, each electronic detonator is deferred while registering.

As described above, the command sent by the control row module is a broadcast command, and each electronic detonator can receive the command. If in the above embodiment 6, the deferral setting instruction includes only the extension of the electronic detonator, the plurality of electronic detonators on the link do not know which of these extensions is their own extension. If the deferred setting instruction includes both the sequence number and the electronic detonator extension corresponding to the sequence number, each electronic detonator can accurately determine its own extension and store through the above steps 311 and 312. It should be noted that the extension of the electronic detonator can be either an absolute extension or a relative extension, wherein the relative extension also includes a reference value for the extension. The concept of absolute extension and relative extension is described in the PCT patent application (International Publication No. WO2015109417), and will not be repeated here.

In step 206, step 306 and step 406 of the above embodiments 4, 5 and 6, the response signal sent by the electronic detonator to the control panel module may include an electronic detonator preset ID. In this case, in step 207, step 307 and step 407, the control row module can store the electronic detonator preset ID and the electronic detonator sequence number corresponding to the electronic detonator to the electronic detonator preset ID and the electronic detonator sequence number. In the table.

In addition to the sequence number of the electronic detonator, alternatively, the electronic detonator setting parameter may also be an electronic detonator network address. The electronic detonator network address is the unique address of the electronic detonator in the detonating network (composed of multiple links) and is the unique identifier of the electronic detonator in the detonating network. Electronic detonator network address can for example It is in the form of "AA: BB". Where "AA" represents the order of the control row modules in the network, and "BB" represents the position of the electronic detonators registered to the control row modules in the link. For example, the network address of the fifth electronic detonator in the link of the second control panel module in the network may have the form of "02:05".

After all the electronic detonators are connected to the link through the electronic detonator connector, the present invention may further include an electronic detonator inspection step. During the process of registering and registering each electronic detonator, the detection process of the electronic detonator has actually been completed. This is because if the electronic detonator cannot communicate, the electronic detonator cannot send an acknowledgement signal to the control bank module. However, after the electronic detonator is connected to the link and registered, even after the extension has been set, for various reasons, the explosion command will not be initiated immediately. During this time, electronic detonators will be affected by a variety of human or environmental factors. For example, the impact of the impact includes that during the construction process, the electronic detonator of the access link may be unintentionally pulled by the construction personnel or the connecting line may be unintentionally pulled; environmental factors include the flooding of the electronic detonator caused by rain. Therefore, the most prudent method is to issue a patrol instruction to the electronic detonator before initiating an explosion command under the electronic detonator. The process is as in Example 7 below.

Example 7

After the

step

107, 210, 310 or 413, the control row module sends a patrol instruction to the electronic detonator in the link. If the control row module stores the electronic detonator preset ID, the inspection command includes an electronic detonator preset ID.

The electronic detonator receives the inspection instruction and extracts the electronic detonator preset ID therein. Then the electronic detonator compares the stored electronic detonator preset ID and the extracted electronic detonator preset ID, if the two are consistent, then Returns a patrol feedback signal including the electronic detonator preset ID.

The control row module collects the patrol feedback signal. If the feedback signal of all the electronic detonators is received, the electronic detonator in the link has no problem, and the subsequent detonation command sending process can be continued. If the feedback signal of all electronic detonators is not received, the electronic detonator preset ID of the feedback signal is determined, and the electronic detonator of the problem is determined by the electronic detonator preset ID and the electronic detonator sequence number/electronic detonator network address correspondence table. And replace it.

Example 8

The invention also includes a detonation command transmission process. After all the electronic detonators are connected to the link and set a delay, or after the inspection, the initiator sends a detonation command to the control module, and the control module forwards the detonation command to the electronic detonator, and the electronic detonator detonates after reaching the set delay. .

Example 9

In the above embodiments, for the convenience of implementation, when the electronic detonator connector is connected to the link and judges that it is not registered, the first indicator signal may also be sent to indicate the registration process. That is, after step 105 and before step 106, after step 205 and before step 206, after step 305 and before step 306 and after step 405 and before step 406, the electronic detonator connector can issue a first indication signal.

Similarly, after the registration is completed, the electronic detonator connector can also issue a second indication signal indicating that the registration process is complete. That is, after step 106 and before step 107, after step 209, and step 210 Prior to, after step 309 and before step 310 and after step 409 and before step 410, the electronic detonator connector may issue a second indication signal.

In addition, when accessing a new electronic detonator connector, ie, the first step (

steps

101, 201, 301, and 401) of Embodiment 3-6, if a new electronic detonator connector is not connected in the link The first electronic detonator connection (ie the second electronic detonator connection, the third electronic detonator connection, ...), the third electronic detonator connection gives a third indication when the new electronic detonator connection is accessed signal.

In the present invention, since the control row module presets the electronic detonator parameters, and in combination with the above state indicating module, the electronic detonator can be quickly connected, and the detonator delay setting is completed at the same time. The function of rapid deferral setting of the detonator is realized, which greatly reduces the labor intensity and technical complexity, and makes the electronic detonator have the connection fastness of the non-electric detonator, and at the same time has the high precision and high reliability of the electronic detonator.

The above is only a preferred embodiment of the present invention, but the scope of the present invention is not limited thereto, and any person skilled in the art can easily think of changes or within the technical scope disclosed by the present invention. Alternatives are intended to be covered by the scope of the present invention. Therefore, the scope of protection of the present invention should be determined by the scope of the claims.
