Description
Technical Field
The invention relates to the technical field of communication signal equipment, in particular to a mining digital leakage communication signal implementation technology.
Background
The existing mining leakage communication signal system is a communication signal system based on analog signal transmission, and is mainly used for transportation scenes such as mining winch transportation, monorail crane transportation, belt transportation and the like. In the mining leakage communication signal system, before a winch, a monorail crane or a belt and the like run, a signaler communicates dotting signals with a base station where a winch driver is located through a hand-held machine, and after receiving a dotting instruction, the winch driver can control driving according to the dotting instruction. Therefore, the signal reliability of the dotting instruction is the fundamental guarantee of the safe operation of equipment such as a winch, a monorail crane, a belt and the like.
Under the severe and special electromagnetic environment in the underground of a coal mine, when the conventional communication signal system performs dotting signal operation based on analog signal transmission, the link detection between the handset and the base station cannot be performed, so that the reliability of dotting signals at each time cannot be ensured, the handset and the base station of the signaler can be in a state of sporadic disconnection or even long-term disconnection, and thus, the winch operation has a large potential safety hazard. In addition to the signer's handset, there are other handset users (e.g., plumbers, etc.) within the system that cannot issue accurate and efficient dotting instructions when communicating voice over the same channel. Other handset users may also misissue the dotting instruction. These conditions can affect the winch driver to receive the correct dotting instruction and to drive correctly. That is, the current mining leakage communication signal system is limited by a communication system, so that signal engineering signal disconnection cannot be effectively solved, effective signal dotting is performed during multi-user voice communication, confusion is caused by signal dotting possibly performed by multiple people, and further potential safety hazards are brought to winch operation, and the problems are technical problems to be solved urgently.
Disclosure of Invention
Aiming at the defects of the existing mining leakage communication signal system, the invention provides a mining digital leakage communication signal implementation method and system. The realization method and the realization system can effectively solve the problems that the system automatically detects the disconnection signal and outputs a parking instruction in the state of disconnection of the signal engineering signal; when multi-person voice communication exists, data signals (i.e. dotting instructions) can be transmitted in an operation mode at the same time; the master control handset confirmed in the base station can send data signals to perform signal dotting operation, so that operation safety of equipment such as winches is ensured. The realization method and the realization system provided by the invention can be widely applied to mining transportation scenes such as winches, monorail cranes, belts and the like. The implementation method and the implementation system provided by the invention are specifically realized by the following technology.
A mining digital leakage communication signal implementation method comprises the following steps:
Transmitting a network access broadcast, starting a competition master control authority mode, and verifying and judging master control authority and non-master control authority of each handset which is accessed to the network; the number of the handsets with the master control authority is 1, and the handsets with the non-master control authority are shielded from false data signals except for the emergency stop signals;
Monitoring and judging the real-time state of each handset, detecting the out-of-connection handset, and judging the master control/non-master control authority of the out-of-connection handset; if the mobile phone is not connected with the master control authority, immediately sending a parking instruction, canceling the master control authority of the mobile phone, and automatically restarting the competitive master control authority mode; receiving and processing an emergency stop signal of the hand-held machine or a stop signal of the main control hand-held machine, and automatically restarting the competitive main control permission mode;
Based on data time slot and voice time slot allocation transmitted by the same digital phone, synchronizing the system and the handset; transmitting data signals and voice signals between the system and the handsets, and completing data transmission of the handsets with main control authorities while the handsets with non-main control authorities transmit voice signals;
and checking and judging whether the signal sent by the handset is correct.
Taking a specific mining transportation scene of a winch as an example (the working flows of the mining transportation scenes such as a monorail crane, a belt and the like are basically the same), under the scene, a signal worker is generally positioned near a route passed by the winch by holding a hand-held machine, the action of the signal worker is to observe the running condition of the winch and the environmental condition near the route in real time, and a data signal (i.e. a dotting instruction) and voice information are sent by using the hand-held machine; the base station processes and verifies the information after receiving the data signal and the voice signal, then transmits the information to a winch driver, and then the winch driver sends corresponding instructions (uplink, downlink, parking, acceleration, deceleration and the like) to control the winch to operate. The winch driver must carry out corresponding correct operation to the winch according to the data signals sent by the signaler and the base station, and the winch cannot be operated without permission. The winch driver is typically located in front of the base station; the winch is generally controlled to operate by a motor and endless ropes. The control command sent by the winch driver directly acts on the operation of the motor.
According to the mining digital leaky communication signal implementation method provided by the invention, through the integral design of the working flows of the base station and the handset, the authority confirmation of the handset is realized, the automatic monitoring and emergency treatment of the handset disconnection signal are realized, the simultaneous transmission time slot allocation of digital speech is completed, the simultaneous transmission of the digital speech of the data signal and the voice signal is realized, and finally, the timely and accurate transmission of the data signal is ensured without the interference of the voice signal.
In order to avoid the interference of error instructions or other signals sent by different handsets to the receiving of instructions by winch drivers and the safe operation of the winch, the implementation method adopts a mode of competing for the master control authority, namely, all the handsets accessing the network acquire the master control authority in a competing mode. The handset which sends the master control authority application can obtain the master control authority after checking and confirming. The implementation method only confirms that 1 handheld machine has master control authority; once any 1 handset confirms the master control authority, other handsets automatically default to obtain non-master control authority, and simultaneously send relevant notification information to all the handsets accessing the network. When the master control authority of the original master control authority is required to be canceled, any handset which is accessed to the network only needs to send out an emergency stop instruction to enable equipment such as a winch to automatically stop running, or the handset of the master control authority sends out a stop signal to enable the equipment such as the winch to stop running; the system then automatically restarts the competing master authority mode. Only the handset with master control authority can send data signals (i.e. dotting instructions) to control the winch to operate, and the handset without master control authority can only send scram signals and voice signals (i.e. voice call information). If a person holding a handset with non-master authority mistakenly touches a button on the handset for sending a data signal, the button is directly shielded and refused, and no signal is sent.
To realize simultaneous transmission of data signals and voice signals in the same channel without collision, firstly, ensuring the real-time performance of voice needs to be considered, and on the basis, distributing the data signals to be transmitted into specific time slots to be sent out, thereby realizing simultaneous transmission of the data signals and voice data in one channel. Specifically, the time slots are divided into data time slots and voice time slots, and the synchronization of the data time slots and the voice time slots of the system and the handset is completed when the system and the handset are started. The system only transmits data signals in the data time slot, and transmits voice signals in the voice time slot; in contrast, the handset transmits only voice signals in the data slots, and transmits data signals in the voice slots.
The emergency stop signal sent by the system is also sent from the data time slot.
According to the mining digital leakage communication signal implementation method, in order to ensure the accuracy of data signal and voice signal transmission, the state of the handset is required to be monitored in real time, so that the handset in the disconnection state can be detected rapidly.
It should be noted that, the signal sent by the mobile phone may be checked by using CRC16 check (the most commonly used error checking technique in the field of data communication).
Further, if the handset in the disconnection state is a handset with master control authority, immediately sending out a parking instruction, canceling the master control authority, and then restarting the competitive master control authority mode to enable other handsets on the network to obtain the master control authority.
Further, when the real-time state of each handset is monitored and judged, a state inquiry request is sent to each handset which accesses the network periodically, and each handset sends current state information feedback after receiving the state inquiry request;
if the base station does not receive the feedback of the state information, the corresponding handset and the corresponding signaller are subjected to the disconnection recording processing.
Alternatively, the time interval for sending the status query request may be 30ms, or any other time period may be set according to the actual situation.
Further, when the real-time state of each handset is monitored and judged, if the state information feedback of the handset is not received, registering that the corresponding handset and the signal person are in an 'unresponsive' state for 1 time;
if the number of times of the 'unresponsive' state of the handset reaches the preset number of times, the corresponding handset and the signal person are marked as the 'disconnection' state.
Further, sending a network access broadcast, after starting a competition master control authority mode, if a network access request of the handset is received, verifying, registering and updating information of the handset and corresponding signalers, and confirming whether the handset is registered to the network;
If the master control authority application of the handset is received, corresponding handset information and signaller information are registered, and master control authority is granted; once the handset with the master control authority is confirmed, the unique confirmation of the master control authority is completed, and the master control authority notification is issued to the handset in a broadcasting way.
Further, the duration of a data time slot and a voice time slot is set, the data time slot and the voice time slot are transmitted in a circulating way in sequence, so that a base station and a handset are synchronous, and a circulating task is processed; after synchronization, the data time slot of the handset corresponds to the voice time slot of the base station, and the voice time slot of the handset corresponds to the data time slot of the base station; the base station transmits data signals in its data time slots and voice signals in its voice time slots;
the base station receives the data signal or voice signal; if the data signal is the data signal, the data signal is processed and then sent to the handset in the data time slot; if the voice signal is not the data signal, the voice signal is processed and then is sent to the handset in a voice time slot;
when the handset transmits a data signal or a voice signal, if the data signal is the data signal, the data signal of the handset is transmitted in a data time slot, and if the data signal is the voice signal, the voice signal of the handset is transmitted in a voice time slot; and after the transmission is finished, entering a signal receiving state to continuously process the circulating task.
Furthermore, the method for realizing the mining digital leakage communication signal also comprises a system initialization and a system self-checking process. After the initialization and self-checking processes are completed, the system starts the competitive master control authority mode to carry out corresponding subsequent processes.
The invention also provides a mining digital leakage communication signal implementation system, which comprises a base station, a handset, a repeater and a leakage cable;
The base station is a base station in a full duplex mode and is used for sending network access broadcast and executing a competition master control authority mode; monitoring and judging the real-time state of each handset, and sending a parking instruction; processing, receiving and transmitting data signals and voice signals;
the handset is a half duplex mode handset for receiving and transmitting data signals and voice signals;
The repeater and leaky cable are link devices of the system for transmission of data signals and voice signals.
It should be noted that, in the above-mentioned mining digital leaky communication signal implementing system, the base station is a common core device for implementing the whole digital leaky communication signal control in full duplex mode.
Generally, the base station provided by the present invention is in full duplex mode, and the handset is in half duplex mode. The base station is operative to process (including decode) the received data signals (i.e., dotting instructions) and voice signals and to transmit the processed data signals and voice signals, as well as other information, to other handsets and winch drivers.
Compared with the prior art, the invention has the following advantages: the method and the system for realizing the digital leakage communication signals for the mines provided by the invention are specially used for realizing automatic disconnection monitoring and corresponding emergency treatment (namely sending out a parking instruction) of a mobile phone aiming at mining transportation scenes such as a winch, a monorail crane, a belt and the like; the simultaneous transmission of the digital speech is realized, and the data signal (dotting instruction) is not interfered by other signals; the master control and non-master control authority management of the handheld machine are realized, the signal false sending is prevented, and the master control handheld machine is ensured to perform signal dotting operation on equipment such as a winch, a monorail crane, a belt and the like.

Based on the mining digital leakage communication signal implementation system, the mining digital leakage communication signal implementation method provided by the invention specifically comprises the following steps:
The base station sends network access broadcast, starts a competition master control authority mode, and verifies and judges master control authority and non-master control authority of each handset which is accessed to the network; the number of the handsets with the master control authority is 1, and the data signals wrongly sent by the handsets with the non-master control authority are shielded;
The base station monitors and judges the real-time state of each handset, detects the out-of-connection handset and judges the master control/non-master control authority of the out-of-connection handset; if the mobile phone is not connected with the master control authority, the base station immediately sends a parking instruction, cancels the master control authority of the mobile phone and automatically restarts the competitive master control authority mode; the base station receives and processes the emergency stop signal of the handset or the stop signal of the handset of the master control authority, and automatically restarts the competition master control authority mode;
Based on data time slot and voice time slot allocation transmitted by the same data phone, synchronizing base station system and handset; transmitting data signals and voice signals between a base station system and a handset, and completing data transmission of the handset with main control authority when the handset with non-main control authority transmits the voice signals;
And the base station checks and judges whether the signal sent by the handset is correct.
Further, in order to realize the above functions:
(1) After a competition master control authority mode is started, if a network access request of the handset is received, verifying, registering and updating information of the handset and corresponding signalers, and confirming whether the handset is registered to access the network;
If the master control authority application of the handset is received, corresponding handset information and signaller information are registered, and master control authority is granted; once the handset with the master control authority is confirmed, the unique confirmation of the master control authority is finished, and a master control authority notification is issued to the handset in a broadcasting way;
(2) When monitoring and judging the real-time state of each handset, the base station periodically transmits a state inquiry request to each handset which accesses the network, and each handset transmits current state information feedback after receiving the state inquiry request; if the base station does not receive the feedback of the state information, performing the disconnection recording processing on the corresponding handset and the corresponding signaller;
Specifically, if the state information feedback of the handset is not received, registering that the corresponding handset and the signal person are in an 'unresponsive' state for 1 time;
if the number of times of the "unresponsive" state of the handset reaches a predetermined number of times (e.g., 3 times or 5 times), then the corresponding handset and the signal are marked as "out-of-connection" states;
Alternatively, the time interval for sending the status query request may be 30ms, or may be arbitrarily adjusted according to the actual situation.
(3) In order to realize simultaneous transmission of data and voice, the time length of data time slot and voice time slot are set, and the data time slot and voice time slot are transmitted circularly according to sequence, so that the base station and the handset are synchronous, and the circulation task is processed; the synchronized handset data time slots correspond to the base station voice time slots, and the handset voice time slots correspond to the base station data time slots. Namely, the base station transmits data signals in the data time slot of the base station and transmits voice signals in the voice time slot of the base station; correspondingly, the handset transmits the voice signal in the data time slot of the base station and transmits the data signal in the voice time slot of the base station;

In some embodiments, the implementation method further comprises a system initialization and system self-checking process.
For further explanation of the specific functions and purposes of the base station and handset described above, the basic operation of the base station is shown in fig. 1. As can be seen from fig. 1, after the base station system is powered on and started, the conventional initialization and self-checking processes are performed successively, then the network access verification process of all the handsets is completed, and the master control/non-master control authority of each handset is confirmed; then, the allocation confirmation of the data time slot and the voice time slot is carried out, and the synchronization of the data time slot and the voice time slot of the base station and the handset is completed; then, the loop task can be started to be executed, and when the data signal and the voice signal are received, whether the data signal is the data signal or not is judged; if the data signal is processed, the system state is sent to the handset in the data time slot, and if the data signal is the voice signal, the system state is sent to the handset in the voice time slot.
The basic operation of the base station is shown in fig. 2. As can be seen from fig. 2, the handset also performs the process of power-up start-up and initialization; then entering an accepting state, sending a network access application to a base station, completing synchronization after receiving a time slot synchronization signal of the base station, setting a local state as an upper state, entering a formal working state, and starting to process a circulation task; the application and confirmation of the master control/non-master control authority of the handset are completed, for the handset with the master control authority, firstly, whether the handset is in a disconnection state is continuously verified according to the requirement of a base station, and if the handset is in the disconnection state, the process is required to be carried out again; if the signal is normally on-line and when the signal transmission task is received, judging whether the signal is a voice signal or not, if the signal is the voice signal, transmitting the voice signal in a voice time slot, and if the signal is a data signal, transmitting the data signal in a data time slot; and then re-enter the normal loop task state.
The operation of the bs system for the contention master authority mode is shown in fig. 3. A signaler with a mobile phone uses the mobile phone to send registration information and identity information of the signaler to a base station, and the base station verifies and registers relevant verification information of the mobile phone and the identity information of the signaler; the signaller then uses the handset to send a data signal (dotting signal) to the base station, i.e. a master authority application is sent; the base station confirms and registers the master control authority of the handset, and broadcasts and transmits the master control authority notice of the handset, and updates other handsets to be non-master control authorities. One and only one handset has master control authority, and once other handsets have acquired the master control authority, the other handsets cannot issue a master control authority application. The non-master authority handset can only send a scram instruction or send a voice signal or voice call. All non-master handsets will also be informed of the current state of the base station system, but only the master authority handsets will send out data signals (i.e. dotting instructions for controlling the operation of the winch etc. devices).
By the method shown in fig. 3, the base station gives different authorities to the main control handset and other handsets, ensures that the data signals are not interfered, ensures reliable signal dotting and ensures the safety of driving signals.
The process of monitoring the real-time status of each handset and determining the loss of handset by the base station system is shown in fig. 4. To perform the function of monitoring each handset, especially the master authority handset, the base station sends a status information inquiry request to each handset in a loop at specific intervals (e.g., 30ms or other time intervals) according to all handset ID information registered for network access. After each handset receives the request, the handset automatically sends its own status information feedback to the voice signal unit, so that the base station system can receive all the status information of handsets registered in the system in real time.
If a handset cannot receive the status information inquiry request sent by the voice signal unit or cannot feed back the status information of the handset for some reason (such as damage to the handset, unsmooth signal, temporary separation of an annunciator, etc.), the voice signal unit cannot receive the status information feedback of the handset, and the system determines that the handset confirms "disconnection" (and loss of connection of the system) at this time. If the master control handset is in the 'disconnection', the system immediately sends out a control instruction for stopping the operation of the winch immediately.
All network-connected handsets, whether having master control authority or not, can send out emergency stop signals to control equipment such as winches to stop suddenly. And once the base station receives the emergency stop signal sent by the handset, the base station processes the signal preferentially and controls equipment such as a winch to be in emergency stop, and simultaneously restarts the competition master control authority mode.
In some embodiments, as shown in fig. 4, the above procedure can be further subdivided into specific steps for further flexible control of the handset:
(1) If the handset that is transmitting the command signal fails for unknown reasons, it cannot receive the inquiry signal of the base station system or transmit its own status information to the base station. Then the base station cannot receive the status information of the handset currently transmitting the command signal. At this point, the system will record the number of times the handset information was not received ("unresponsive" status);
(2) The number of "unresponsive" times is accumulated more than n times (n is a parameter that can be adjusted according to the needs of the system, typically 3 or 5 times is chosen), and the system determines that the handset is in a "disconnected" state (i.e., disconnected from the base station system); if the 'out-of-connection' handset is a handset with master control authority, the system can immediately output a parking control signal, ensure the operation safety of a winch and the like, cancel the master control authority of the handset and restart a 'competing master control authority mode'; if the handset is a handset with the authority of 'non-master control', the handset is used as a common handset to carry out corresponding control treatment in a disconnection mode;
if the number of times of the 'unresponsive' state is not N, the system carries out warning processing and circularly carries out the next state information inquiry request.
The basic flow of processing of data signals (dotting signals) and voice signals for two slots (data slots and voice slots) of a handset with master authority is shown in fig. 5. In fig. 5, the base station first confirms the duration of the data slot and the voice slot, and the base station and the handset complete double slot synchronization; the handset processes and plays the voice if receiving the voice signal, and judges whether the handset is a handset with master control authority if needing to send the data signal; if yes, the data signal is sent in the data time slot, if not, whether the data signal is an emergency stop instruction is judged, if yes, the data signal is sent in the data time slot, and if not, no data signal is sent.
The wireless data protocol in this embodiment is shown in tables 1-4 below.

To realize simultaneous transmission of data and voice in the same channel without collision, firstly, it is considered to ensure the real-time performance of voice, and on the basis, the information of the data signal (control data) to be transmitted is distributed into the time slot of the system to be sent out, so that the simultaneous transmission of the data signal and the voice signal (voice data) in one channel is realized. Therefore, for voice real-time performance, the present embodiment designs a voice packet, the transmission interval is 30ms, a single time slot length is 30ms, and the voice time slot and the data time slot are transmitted in a cyclic manner in sequence. A diagram of slot allocation for both base station and handset data transmission is shown in fig. 6.
In fig. 6, the horizontal axis is time, and 60ms is a time period, and the base station distributes time slots, i.e., data time slots and voice time slots. The base station can receive at any time without time division. Assuming that handset MS1 starts transmitting voice at t=60, MS3 transmits data at t=90 MS, MS5 transmits data at t=150 MS, and all other handsets are in the receive voice and data states, the transmit state and receive state slot assignments are shown in fig. 6.
