Detailed Description

In order to make the objects, technical solutions and advantages of the present invention more apparent, the present invention will be described in detail with reference to the accompanying drawings and specific embodiments.

As shown in fig. 1 to 3, the present invention discloses an indicating device, which is used to cooperate with a control terminal of a base station to display the position of the indicating device, wherein the indicating device comprises a housing, an LED indicator, a power module 4, a wireless communication module, a display screen 3 and a circuit board 6.

The shell is used for accommodating the circuit board 6, the LED indicator light, the display screen 3, the wireless communication module and the power module 4. Referring to fig. 2 and 3, specifically, the housing includes a first housing 1 and a second housing 2 connected to the first housing 1, an accommodating space for accommodating the circuit board 6, the power module 4 and the display screen 3 is formed between the first housing 1 and the second housing 2, and the power module 4, the LED indicator light, the display screen 3 and the wireless communication module are all integrated on the circuit board 6. The first housing 1 is provided with a buckle 10, and the second housing 2 is provided with a clamping groove 22, so that the buckle 10 of the first housing 1 can be inserted into the clamping groove 22 of the second housing 2 to assemble and fix the first housing 1 and the second housing 2. When the first housing 1 and the second housing 2 are assembled and fixed, the accommodating space may be formed inside the first housing 1 and the second housing 2.

The display screen 3 is arranged on the front surface of the second shell 2, is connected with the LED indicating lamp and is used for displaying corresponding text and/or digital prompt information when the LED indicating lamp is lightened; the wireless communication module is in wireless communication connection with the control end and the LED indicating lamp and is used for receiving control data sent by the control end and sending a control instruction to the LED indicating lamp according to the control data so as to light on/off the LED indicating lamp. That is to say, the control data that the control end sent is by wireless communication module conveying to the LED pilot lamp to make the LED pilot lamp show light, simultaneously, display screen 3 shows the prompt message.

The LED indicator light is a red, green and blue LED indicator light and is used for splicing and displaying light with different colors according to different control instructions sent by the control end. The control instruction can also control the brightness and the lighting time of the light and the interval time of the light extinction.

The indicating device is internally provided with an electronic tag, namely an RFID tag, and is used for writing in a Bluetooth MAC address to carry out address binding on the library position and the LED indicating lamp. Specifically, the RFID tag is disposed inside the first housing 1, and is disposed away from the display screen 3. The traditional indication reminding device adopts the traditional paper bar code for address binding, the number of the devices is extremely inconvenient to later modification, update or expansion after one-time deployment, the requirement on the skills of installation and deployment personnel is too high, and an ordinary user cannot directly change the address binding. The RFID tag is combined with the LED indicator lamp, and a conventional Bluetooth MAC paper binding bar code of the light bar is eliminated. Specifically, a read end of the RFID tag is added in the indicating device, and the Bluetooth MAC address is directly written into the content of the RFID tag. The setting ensures that the address binding has no redundant action, greatly improves the efficiency and saves the production cost.

The indicating device of the present invention is mostly applied in the industry of warehouse management, and the working principle and the working process of the indicating device will be described in detail below by taking warehouse management in a warehouse as an example.

Because the storeroom is provided with a plurality of goods shelves, the indicating device is a light bar consisting of a plurality of LED indicating lamps, and information is transmitted between the light bar and the control end through the wireless communication module. That is to say, wireless communication module is connected with control end and lamp strip wireless communication respectively. The power module 4 is integrated in the shell of the indicating device and used for supplying power to structures such as an LED indicating lamp, a circuit board 6 and a display screen 3 in the lamp strip.

Specifically, the LED indicator is a red, green and blue LED indicator, and a read end of the RFID tag is added inside the light bar (indicator), so as to directly write the bluetooth MAC address into the tag content. Specifically, the hardware address of the wireless communication module of the light bar is stored in the RFID tag, and when a user performs a binding operation between the light bar and an article, the hardware address of the wireless communication module of the light bar can be quickly obtained through the RFID card reader, and information of the bound article is uploaded to a base station or other hosts. That is to say, the RFID tag is added inside the light bar, so that the address on the shelf can be bound. The control data or the control instruction sent by the control end is wirelessly received by the wireless communication module and then wirelessly transmitted to the LED indicator lamp. The unbinding between the lamp strip and the object can input object information at the control end of the base station, and the binding relationship is directly released. Specifically, the binding state is set: bind command + status, bind command-0A; state-00: unbinding; 01: and (6) binding. For example, (0A, 00) indicates that the light bar is unbound, and (0A, 01) indicates that the light bar is bound.

Because the LED pilot lamp is red yellow blue tristimulus LED pilot lamp, so red yellow blue tristimulus LED pilot lamp can piece out different colours according to receiving different control command or data. Such as: the commodities of all the living goods in the warehouse need to be sorted out for re-management and monitoring, managers can set the commodities of all the living goods in the warehouse as yellow control instructions in the control end, and due to the fact that address binding is carried out on the light bar of the shelf in advance, each red, green and blue LED indicator light on the light bar corresponds to various commodities. When the control end sends out a yellow control instruction or data, the light bars (LED indicating lamps) on the commodities of all the daily necessities on the goods shelf can display yellow light. Therefore, all the commodities of the daily use articles on the shelf are sorted out. By the arrangement, the working efficiency is greatly improved, and time and labor are saved. The mode of wireless communication reduces the complexity of the connection of the indicating device. As another example, different colors may also represent different states in a particular scene: in the logistics picking link, a picking position can be delivered to the employee A when a green light is turned on; and a bright blue light indicates employee B's delivery location.

In addition, the control end is also used for controlling the brightness, the lighting time and the light-out interval time of the red, green and blue LED indicator lights. That is to say, the base station is connected with the lamp strip through the wireless communication module, not only can send the colour control command of light, can also send control commands such as the luminance that light was lighted, the time of lighting and the interval time that light goes out. For example, the time length of lighting the color lamps, the time length of turning off the lamps, the number of cycles of lighting and turning off the lamps, and the like are set. Since the goods in the warehouse need to be updated frequently, including the number and the variety of the goods, the user can set the brightness of the light emitted by the LED indicator lamp at the control end to be related to the number or the variety of the corresponding goods. For example: when the red, green and blue LED indicator lights corresponding to the commodities, if the brightness of the lights emitted by the LED indicator lights is dark, the quantity of the commodities is small, and the commodities need to be replenished by workers, otherwise, the commodities are opposite.

The user can also set the control end according to the actual requirements in the warehouse for the lighting time or the lighting interval time. The arrangement is favorable for the flexible application of the indicating device according to the actual situation and the development of the subjective activity of managers or users.

The control of the control end of the base station on the parameters of the LED indicator lights in the indicating device (light bar) will be exemplified below. Setting a control instruction format:

LED pilot lamp: lamp color + cycle times + lighting time + lamp-out time;

color of the lamp: 0-off; 1-red color; 2-green; 3-yellow; 4-blue; 5-purple; 6-cyan; 7-white;

cycle number: 0 to 255;

lighting time: 0 to 255 (unit: 100 msec);

and (3) light-out time: 0 to 255 (unit: 100 msec);

examples are: (00, 05, 03, 03) indicates that the light is turned off and the latter parameter is invalid;

(01, 05, 03, 03) showing that the red light is turned on, the red light is turned on for 300 milliseconds first and then turned off for 300 milliseconds, the operation is repeated for 5 times, the total light control time is 5 x (300+300) to 3000 milliseconds, the visual effect is that the red light flickers for 5 times, all the LED indicating lamps are turned off after the circulation is finished, and the light bar enters a low power consumption state to save the electric quantity;

(02, 05, 03, 03) showing that the lamp is on green, the lamp is firstly on for 300 milliseconds, then is off for 300 milliseconds, the operation is repeated for 5 times, the total lamp control time is 5 x (300+300) to 3000 milliseconds, the visual effect is that the lamp flashes for 5 times, all the LED lamps are turned off after the circulation is finished, and the lamp bar enters a low power consumption state to save the electric quantity;

(03, 05, 07, 00) shows that the yellow light is turned on, the total light control duration is 5 x (700+0) ═ 3500 milliseconds, the visual effect is that the yellow light is kept on for 3500 milliseconds, all the LED lights are turned off after the circulation is finished, and the light bar enters a low power consumption state to save the electric quantity.

Furthermore, the indicating device also comprises a buzzer matched with the LED indicating lamp, and when the LED indicating lamp displays corresponding light, the buzzer can synchronously send corresponding prompt sounds. In reality, the warehouse is big or small, and if the warehouse meets a large-scale warehouse, the position of user materials is prompted only by light emitted by the red, green and blue LED indicator lamps, and the workload can be increased to a certain extent. That is, the buzzer serves as a guide for the general range, lighting an indication of a particular location/cargo. In some scenes, due to the reason of layout blocking, each light bar cannot be directly visible, and at the moment, a buzzer buzzing mode can be used for guiding a user to an approximate position, and then a specific target can be found according to light-on indication. The indicating device is additionally provided with the buzzer matched with the LED indicating lamp, and the purpose of the arrangement is as follows: the position of the goods and materials on the goods shelf can be positioned more quickly by a user.

Furthermore, the buzzer can also receive and process the control instruction or data sent by the control end independently, and send out corresponding prompt sound according to the control instruction sent by the control end. The control end can also control the characteristics of the sound emitted by the buzzer, the sounding time, the pause time, the cycle times and the like. The LED pilot lamp on the lamp strip can hardly damage the situation, the buzzer can receive and process control data sent by the control end independently, and the goods can be positioned quickly even if the LED pilot lamp is damaged and light cannot be sent. That is to say, when the control end sends control command and passes through wireless communication module and transmit to the red green blue tristimulus LED pilot lamp that corresponds with commodity on, and red green blue tristimulus LED pilot lamp does not send light because of damaging, and at this moment, the buzzer that corresponds sends suggestion sound to inform user's position of commodity and locate.

In addition, according to the actual condition requirement of the warehouse, the user can control or set parameters such as the size of the prompting sound sent by the buzzer, the sounding time, the pause time, the cycle number and the like. Such as: the control end carries out corresponding light control to red, green and blue three-colour LED pilot lamp through wireless communication module, also can control the suggestion sound that buzzer sent simultaneously. For example, the user may set different prompting sounds at the control end, specify a certain prompting sound to indicate the variety or quantity range of the commodity, and quickly locate the position of the commodity according to the emitted light and the prompting sound, and quickly judge the specific situation of the commodity, for example, if the quantity range of the commodity is lower than a specified value, judge that the commodity needs to be restocked. The purpose of this is to: the indicating device can be flexibly applied according to actual requirements, a user can quickly locate the position of the commodity, and the specific situation of the commodity can be roughly judged in a very short time.

The control of the control end of the base station on the parameter of the buzzer in the indicating device (light bar) will be exemplified below. Setting a control instruction format:

a buzzer: buzzer switch + cycle number + turn-on time + turn-off time;

a buzzer switch: 08-turn off the buzzer; 09-turn on the buzzer;

cycle number: 0 to 255;

opening time: 0 to 255 (unit: 100 msec);

closing time: 0 to 255 (unit: 100 msec);

examples are: (08, 06, 03, 02) indicates that the buzzer is turned off and the latter parameter is invalid;

(09, 06, 03, 02) indicates that the buzzer is turned on, the buzzer is turned on for 300 milliseconds first, then turned off for 200ms, and the above steps are repeated for 6 times, the total control time length is 6 x (300+200) ═ 3000 milliseconds, the effect is that the buzzer drips and rings for 6 times, the buzzer is turned off after the circulation is finished, and the light bar enters a low power consumption state to save the electric quantity;

(09, 06, 04, 00) indicates that the buzzer is turned on, the total control time length is 6 x (400+0) ═ 2400 milliseconds, the effect is that the buzzer sounds for 2400 milliseconds, the buzzer is turned off after the cycle is finished, and the light bar enters a low power consumption state to save the electric quantity.

According to the utility model, the control of the LED indicator light and the control of the buzzer are completely independent in time and do not conflict with each other, the control instruction of the buzzer can be sent when the LED indicator light is in control, one instruction can also simultaneously contain the LED indicator light, the buzzer and the control information bound in state, and the light bar does not enter the low power consumption mode until the last control is finished.

Of course, in the application, the user may perform the combined setting control on the parameters or the characteristics of the LED indicator and/or the buzzer according to the actual requirements, or may perform the combined setting control on the usage of the LED indicator and the buzzer, which is not limited to this.
