[0036] Figure 1 This is one of the structural schematic diagrams of the explosion-proof controller provided by the utility model; Figure 2 This is the second structural diagram of the explosion-proof controller provided by the utility model; Figure 3 This is the third structural diagram of the explosion-proof controller provided by the utility model; Figure 4 This is the fourth structural diagram of the explosion-proof controller provided by the utility model, please refer to Figures 1 to 4 The utility model provides an explosion-proof controller, which includes: a housing 10, a display panel 20 and a control unit.

[0037] The housing 10 is used to protect the display panel 20 and the control unit. Specifically, an opening 11 is provided on the end surface of the housing 10, and a plurality of interfaces are provided on the side surface of the housing 10. That is, the opening 11 and the interface are on different surfaces, the opening 11 is used to plug in the display panel 20, and the interface is used to connect other devices.

[0038] The control unit is used for communication connection with other devices, and the cables between the control unit and other devices pass through the above-mentioned interface. In addition, the control unit is connected to the display panel 20 for communication, and the display panel 20 is used for displaying the content transmitted by the control unit.

[0039] The display panel 20 is plugged into the opening 11 of the housing 10 to display the content transmitted by the control unit. In addition, an indicator light 21 is provided on the display panel 20. Based on the instruction sent by the control unit, the indicator light 21 can light up to provide instructions to the staff.

[0040] The explosion-proof controller provided by the utility model can display the content transmitted by the control unit by inserting the display panel 20 into the opening 11 of the housing 10 and making the control unit communicate with the display panel 20. In addition, an indicator light 21 is provided on the display panel 20, and the indicator light 21 can light up based on the instruction sent by the control unit, thereby enhancing the function of the explosion-proof controller and being able to display more content, thereby providing instructions for the staff.

[0041] Specifically, this explosion-proof controller can be used for on-site maintenance, calibration, and viewing of gas detectors that are inconvenient for personnel to reach or maintain during gas monitoring. In the monitoring of flammable and toxic gases, in some applications, it is inconvenient or impossible for operating and maintenance personnel to reach the vicinity of the gas detector - for example, when the gas detector is installed too high or above the liquid storage tank, it is difficult to perform normal maintenance, calibration, and viewing of the instrument. Under such conditions, other solutions may pose a safety hazard to maintenance operators.

[0042] The explosion-proof controller can remotely set, display, alarm and calibrate the gas detector, which can effectively avoid the danger of human operation and the difficulty of operating the gas detector. These remote setting, display and alarm functions are completely synchronized with the gas detector, so it can work safely in dangerous areas.

[0043] The above explosion-proof controller can be installed on-site to centrally manage the on-site gas detectors. Through the control unit, the gas detectors can be operated and set through the explosion-proof controller. Specifically, the gas detectors can be remotely calibrated.

[0044] The concentration information of the gas detector can be remotely displayed through the display panel 20. Specifically, it can be a self-luminous OLED. The display screen of the self-luminous OLED is convenient for full-angle viewing in a high-brightness environment. Based on the accident information and event information sent by the control unit, the display panel 20 can also display it, so that the explosion-proof controller has accident display function and event recording function.

[0045] At the same time, the indicator light 21 on the display panel 20 can display the signal sent by the controller, such as an alarm signal. The indicator light 21 is an automatic high-brightness LED. When an alarm or other information appears, the high-brightness LED flashes to alarm based on the control of the control unit. Specifically, the indicator light 21 can indicate different contents by lighting up in different ways, for example, it can flash or stay on.

[0046] Furthermore, the explosion-proof controller and explosion-proof flammable and toxic gas controller have high limit and high-high limit alarm functions, and can be used in conjunction with the sound and light alarm to complete the on-site sound and light alarm function.

[0047] The control unit is used to communicate with other devices. For example, the explosion-proof controller is also connected to the relay. By sending alarm and fault information to the relay, the relay can be controlled to automatically disconnect to avoid operating failures and reduce losses.

[0048] The explosion-proof controller is designed and manufactured based on the internationally advanced modular technology, and is used to continuously monitor the combustible gas, oxygen or toxic gas in industrial hazardous areas. It adopts advanced microcomputers and mature and reliable circuit design, is fully digital, and has a highly intelligent operation mode. It has functions such as self-test, alarm, and information storage.

[0049] The explosion-proof controller is used to connect a certain number of gas detection instruments around the site to centrally manage the on-site gas detectors. This explosion-proof controller connects to the surrounding gas detectors through HABUS. By operating the explosion-proof controller, the concentration display, setting, calibration and other operations of the detectors can be completed, which is convenient for users to understand the working conditions of the on-site gas detectors.

[0050] The communication between the explosion-proof controller and the gas detector is completed by the HABUS bus digital communication protocol. The explosion-proof controller completes the communication between the controlled gas detectors at most once every 5 seconds. The explosion-proof controller sends a query command to the controlled gas detector. After receiving the query command, the gas detector will feed back the parameters of the instrument to the explosion-proof controller, and complete a round of communication after sending a group of query commands to the controlled gas detector in turn. The HABUS communication protocol is selected because this protocol has high stability, and the communication rate reaches a baud rate of 9600bps, which can fully meet the communication requirements between devices. The requirements for anti-interference and reduced bit error rate in device communication are guaranteed.

[0051] In an embodiment provided by the present invention, the plurality of interfaces include: a gland interface 12, which is detachably connected to the side of the housing.

[0056] It should be noted that the explosion-proof controller can provide 1 to 16 channels. This explosion-proof remote controller adopts a flexible channel configuration mode to adapt to field applications of different scales. For each additional channel, you only need to connect the corresponding gas detector to the bus.

[0057] Furthermore, in an embodiment provided by the present utility model, the control unit has at least one channel, and each channel corresponds to an explosion-proof junction box.

[0058] Specifically, the explosion-proof controller, explosion-proof combustible and toxic gas controller and gas detector communicate via the HABUS bus digital communication protocol, and one controller can control up to 16 gas detectors. The explosion-proof controller and gas detector use digital communication, and only need to add communication cables between the junction box and the gas detector, such as positive and negative poles, S_O signal lines, I_O signal lines, etc., to add the explosion-proof controller to the gas detector and gas alarm controller network without affecting the normal operation of the network, and can achieve the above-mentioned monitoring, calibration and other functions.
