Description

Technical Field

[0001] The present invention belongs to the technical field of walkie-talkie group team formation, and relates to a team management method and system for a team, in particular to a method and system that can realize fast and safe team formation and team walkie-talkie equipment collection and return management. Background Art

[0002] In the tourism industry or outdoor sports market, team members often need to talk to each other. However, each time they use the intercom, they need to reset the team after receiving the intercom equipment to ensure that team members can talk to each other after teaming and avoid frequency interference with other teams' intercom equipment.

[0003] Existing intercom teaming solutions are mostly divided into two types:

[0004] 1. If the walkie-talkie frequency is known, manually select the same frequency or set it to the same channel using a frequency programming cable and PC-side frequency programming software.

[0005] 2. Another method is to use a frequency reader to read the frequency of the walkie-talkie, manually select the same frequency or set it to the same channel through a frequency writing cable and PC-side frequency writing software.

[0006] The drawbacks of the above two methods are that manual configuration limits you to fixed channels, which are limited in number and prone to crosstalk or interference, resulting in low efficiency. Using a programming cable and PC programming software requires carrying the corresponding programming cable and PC, making operation cumbersome. Furthermore, group rental and return of walkie-talkie equipment is cumbersome and lacks team-based management. Summary of the Invention

[0007] In order to solve the technical problems of work efficiency and management efficiency in the overall rental and return of walkie-talkies by a team, the present invention designs a team management method and system for walkie-talkies. A team management terminal is added to the charging device to achieve fast and safe team formation and team walkie-talkie equipment collection / return management.

[0008] The technical solution adopted by the present invention is a team management method for walkie-talkies. The method is implemented on a charging system consisting of a charging device and a group of walkie-talkies. A team management terminal is added between the charging device and the walkie-talkies. The team management terminal stores the team ID code and the ID codes of all walkie-talkies. On this basis, the team management method is specifically as follows:

[0009] When using a walkie-talkie,

[0010] a. Enter the team ID code and the quantity required to be collected into the team management terminal;

[0011] b. Select the pre-rented intercom, the intercom sends a use request instruction containing the intercom ID code to the team management terminal;

[0012] c. The team management terminal sends the authorized configuration information to the pre-rented intercom according to the team ID code;

[0013] d. The pre-rented intercom sends confirmation information to the team management terminal to complete the rental process, and when returning the intercom,

[0014] e. After inserting the intercom to be returned into the charging interface, the intercom to be returned sends a request return instruction containing the intercom ID code to the team management terminal;

[0015] f. The team management terminal compares the intercom ID code to be returned with the authorized configuration information sent, and after successful comparison, the team management terminal sends confirmation information to the intercom to be returned to complete the return process, and simultaneously sends a charging instruction; if the comparison is unsuccessful, an alarm prompt is sent.

[0016] In step c, the authorized configuration information contains the intercom channel information and CTCSS sub-audio information.

[0017] The team management terminal defaults to start the charging instruction before the intercom is rented, and sends an exit charging instruction when the intercom is rented.

[0018] In step f, the team management terminal sends confirmation information to the intercom to be returned in the following manner: the team management terminal sends a verification request instruction containing a set of randomly generated 8-bit random numbers, the intercom to be returned calculates the plaintext according to its own key and the 8-bit random number, and simultaneously packs the plaintext and the intercom ID code into a return instruction and transmits it to the team management terminal, the team management terminal receives the plaintext sent by the intercom and performs verification, and simultaneously identifies the team ID number according to the intercom ID code, and the team management terminal sends confirmation information to the intercom to be returned.

[0019] The sub-audio monitoring module is provided in each intercom, and when the sub-audio monitoring module detects that there is a signal on the current channel, but there is no CTCSS sub-audio or the CTCSS sub-audio does not match the CTCSS sub-audio set by the intercom, the intercom device will automatically increase and switch to the second channel to work, taking the second channel as the main channel and the previous channel as the slave channel.

[0020] The way to switch to the second channel is to increase 1Mhz on the basis of the frequency of the current channel.

[0021] The present invention also relates to a team management system for walkie-talkies, which is used for the above-mentioned management method. The management system includes a charging device, a group of walkie-talkies, and a team management terminal connected between the charging device and the walkie-talkies. The team management terminal is provided with a power supply circuit, a group of charging interface circuits for the walkie-talkies, a central processing unit, a button circuit, an indicator light circuit, a display circuit and a speaker circuit.

[0022] The present invention provides the following advantages: through the management of walkie-talkie groups by the team management terminal, teams can be quickly formed in batches. Channels can be allocated through the team management terminal as a whole, preventing interference with the channels of borrowed walkie-talkies. The walkie-talkie equipment also implements channel monitoring, automatically switching channels if the current channel is occupied. The overall management of the team management terminal can monitor the borrowing and return of walkie-talkies by the team, effectively managing the usage of walkie-talkies.

DETAILED DESCRIPTION

[0026] In a specific implementation of the present invention, before the intercom 2 is borrowed, the team management terminal 3 controls the charging device 1 to charge the intercom 2 by default. When a team rents and uses it, the tour guide or team leader enters the team's ID code and the number of intercoms to be used. The intercom 2 receives the required equipment according to the instructions. The intercom 2 receives a request instruction containing the intercom's ID code. The team management terminal 3 allocates configuration information such as the intercom channel and CTCSS sub-audio frequency according to the team ID number. The allocation method is shown in the channel and sub-audio frequency allocation method. The team management terminal 3 sends a configuration information instruction to the intercom 2. After receiving the configuration information instruction, the intercom 2 sends an ACK signal. At this time, the intercom is borrowed and can be used for intercom communication directly.

[0027] When the team uses the intercom and needs to return it, the intercom 2 is inserted into the charging slot, the team management terminal 3 detects the intercom access, sends a verification REQ request instruction, the request instruction contains a set of randomly generated 8-bit random numbers, the intercom 2 calculates the plaintext according to the formula after substituting the random numbers according to its own key, and sends the plaintext and the intercom ID code combination to the team management terminal 3. The team management terminal 3 receives the plaintext sent by the intercom 2 and checks it, and identifies the team ID code according to the current intercom ID code. The team management terminal 3 sends an ACK signal to the intercom 2, and the return is successful. At the same time, the charging function is started. At this time, the team management terminal 3 can view the team ID code of the returned intercom 2 and the remaining unreturned intercom equipment of the team.

[0028] During team intercom use, if the sub-audio monitoring module detects that there is a signal on the current channel, but there is no CTCSS sub-audio or the CTCSS sub-audio does not match the CTCSS sub-audio set by the local machine, it is considered to be other team signals or other interference signals. At this time, the team intercom device will increase and switch to the second channel for work. The CTCSS sub-audio is an audio signal with a frequency of 60HZ-280HZ.

[0029] The intercom standby adopts a double standby module, and can accept signals of two channels at the same time. If the signal of the second channel is detected, the second channel is taken as the main channel and the first channel is taken as the slave channel. If the signal of the first channel is detected, the first channel is taken as the main channel and the second channel is taken as the slave channel. The difference between the main channel and the slave channel lies in the different allocation time sequence ratio, so that the response speed of the main channel and the slave channel is different. The main channel responds quickly. The search time sequence of the main channel and the slave channel is in the proportion of 3:1, that is, the main channel is searched for 3 times and the slave channel is searched for 1 time. For example: the first search period: main channel search 100ms+ standby 300ms, the second search period: main channel search 100ms+ standby 300ms, the third search period: main channel search 100ms+ slave channel search 100ms+ standby 300ms.

[0030] Channel and CTCSS sub-audio allocation method:

[0031] Intercom device working frequency: 400Mhz-420Mhz, channel interval 12.5Khz, total channel capacity: 20*80=1600, each team uses the corresponding team ID code.

[0032] First channel allocation:

[0033] Corresponding formula ID number is odd: FREQ=400Mhz+(1600-2*(ID%800)-1)*12.5Khz,

[0034] The corresponding formula ID number is an even number: FREQ = 400Mhz + (2*(ID%800))*12.5Khz,

[0035] Second channel = second channel + 1Mhz, sub-audio frequency range: 60HZ ~ 280HZ, interval 5hz, a total of 44 groups of sub-audio can be set,

[0036] The corresponding formula ID number is an odd number: FREQ = 60hz + (44-2*(ID%22)-1)*5hz,

[0037] The corresponding formula ID number is an even number: FREQ=60hz+(2*(ID%22))*5hz.

[0038] To implement the aforementioned management method, the present invention also provides a management system comprising a charging device 1, a group of intercoms 2, and a team management terminal 3 connected between the charging device 1 and the intercoms 2. The team management terminal 3 includes a power supply circuit 3-1, a charging interface circuit 3-2 for the intercoms 2, a central processing unit 3-3, a key circuit 3-4, an indicator light circuit 3-5, a display circuit 3-6, and a speaker circuit 3-7. The sub-audio monitoring module detects interference on the current channel when the intercom is in standby mode, and the display circuit 3-6 displays the current usage status of all managed intercoms, including idle and unrented, rented, and rented but not returned. The key circuit 3-4 is used to input commands for receiving or returning intercoms.
